I was super excited and told him that we have to do it but! It has to be a real surprise. Tanaka sensei shouldn’t feel any thing suspicious going on or that someone tells him about it. So we agreed to keep it a secret. (this was one week before our sensei’s birthday), only I, him and Nguyen knew about it. The problem though was that our sensei on his birthday had a business trip and he wasn’t going to be in the lab. Our plan was about to fail! We thought about it then we came up with a new plan. We decided to organizing it on the day of Danwakai (our Lab meeting); in the same week of his birthday. Mostly every body then would be there and it wouldn’t interrupt any body’s work because it was weekend. We knew it was going to be a little bit delayed from the actual date but from an other perspective it was the perfect day. Now to keep things secretive, we had to keep quite and not tell any body in our lab about it till the day of the party. We had to prepare everything beforehand because on the day of party we had Danwakai, a meeting that we couldn’t skip). So we decide to go shopping from Costco (a big supermarket, that sells a lot of goods at reasonable prices especially pastries, 20km from Sendai).
We wanted to go on Friday night, the night before the party but the problem was that how were we going to store the cake that night as the cake would be big. So we went shopping that night at around 7pm and bought the cake and some drinks (we also had pizza and some ice cream as we wanted to have fun that night). When we returned to Sendai afterward and measured the size of the cake, it seemed it wouldn’t fit neither in my fridge nor the Khan’s, so we called a friend who had a bigger fridge. We went to his place, tried to fit cake in his fridge but that didn’t work either . It was a big problem for us, the cake would get ruined if we didn’t cool it during the night. The only solution we could think of so far was to buy some ice and put the cake in a box filled with ice during the night so the cake would stay intact so that’s what we did. I took the cake with me that night, put some ice cubes in the kitchen sink, lay the cake there (the cake was already covered with plastic) and covered the sink. I slept that night well, woke up in the morning, loaded the car with drinks and cake and drove to our university. The plan that morning was to let every body go upstairs to the meeting room and before the end of the meeting we were to unload the car and prepare the party. We attended the meeting that morning as usual and acted that nothing was going on. Before the last presentation (we usually have 4 presentations in each Donwakai), we went downstairs to our lab and tried to act fast. We set the table and the chairs. We put the cake in the middle with some candles (we had only 7 candles so we decorated them on the cake but it didn’t make sense!! everybody later asked what did seven signify?). Then we surrounded the table with coke cans ( the drinks we actually bought were coke cans and green tea), small paper plates and spoons. The room at that moment was missing the surprise element; it was the birthday message that we wanted our sensei to see first when he entered the room. We had printed “Happy birthday Tanaka sensei” on 4 A4 papers and had hanged them on a movable white board. We gave a final check to everything and we went back to the meeting.
Now before the final task we had to inform everybody in the room about the party without letting Tanaka sensei finding out. I had an idea. I asked Fromel sensei for a piece of paper (as he was taking some notes during the meeting using a note book), I wrote a small message telling everybody that today we are celebrating our sensei’s birthday after the meeting but they have to keep quite and try to surprise Tanaka sensei afterwards. Each one read the paper and passed it to the person next to him. All of them read the paper secretly but our sensei. (I was wondering if he had seen some people reading the paper or had sensed something going on especially when the paper reached the first row where he was sitting with rest of the sensei). After the meeting we all packed, set the meeting room back as it was before our meeting and went downstairs, trying to beat Tanaka sensei to the Lab and arrive before him.
We arrived in our lab, turned off the light and started waiting.
Tanka sensei took some time to arrive actually so Khan went out to check on him. He immediately returned in hurry and said ‘’he’s coming, he’s coming. The moment Tanaka sensei opened the door and entered we turned the lights on and everyone said “Surprise!!!”. He really got surprised, then laughed. He was so happy to see that. He didn’t expect it at all (we were also so happy to see him getting surprised). We sang the birthday song for him and he came up to blow off the candles and as expected he asked about the candles’ number. He said that it wasn’t related to his age or something else.
We explained to him that they were all what we had so we used them. He blew over the candles and every body clapped. The cake was big and it wasn’t obvious how to cut it. So the girls Nguyen and Thao helped him for that.
We were supper hungry; by then it was almost 1 pm and no body had taken his lunch. They cut us big pieces, I was glad they did that and almost all of us finished the cake, it was delicious. Our sensei gave us a small speech afterwards. He said he was really surprised by the party and was very happy. He thanked everybody for the day and said he appreciated everything. We had so much fun that day. Members of our lab were hanging out, every body was happy for Tanaka sensei.
I admit that we have attended other parties before in our lab as we usually celebrate different occasions like welcoming new members to our lab or at the graduation of other member but this one was special. This one was the first time that we celebrated something that concerns our sensei. So it felt special. The thing that we didn’t prepare thought was the presents but we decided that next time we would try to make a better plan because there will be a next time for sure. We have already decided to redo it next year hopefully on the exact date of our sensei’s birthday and also have to think about an element of surprise because we know that next time our sensei will suspect things and when he reads my blog he will definitely know (Let’s see how it goes next year!).
Hello. This is Satoru Akita, M1 student.
I report about "science cafe" held at Sendai Media Work on August 25th last month.
Science cafe is a lecture sponsored by Tohoku University to "make learning more familiar and more fun". Every month the university researchers talk about their research to the general public, the science café in the science field, and the liberal arts field as the liberal arts salon. (Some past lectures are posted on Youtube.)
Last month Professor Tanaka, who is our laboratory leader gave a lecture.
The theme is "Small sensor to feel the shake of the smartphone,which greatly change society～MEMS and IoT～.
・Introduction of MEMS sensor in smartphone
・Measurement principle of MEMS
・How to make MEMS on silicon wafer
・Importance of microfabrication technology
・Application to VR · AR, voice assistant, automatic driving etc
these are abstract content.I also learned a lot :)
In the lecture of the day, more than 100 people including elementary school students and elderly people, including related researchers, visited us and each table became full.
After the lecture, there was an event to think about applications using sensors on each table. Various ideas such as pen to measure concentration of study, eyeglasses corresponding to various degrees, machine to calculate automatically, etc. came out.
Finally We took a group photo with Tohoku University Public Relations staff, media work staff and facilitators. Thank you for the day! !
Dear Tanaka Lab’s student blog reader,
This is Salman, an M2 student who have stayed at Fraunhofer ENAS in Germany for the past 5 months. Here I would like to report about the so called Chemnitzer Seminar 2017, which was held just before my departure back to Japan.
On 13-14 June 2017, I had a chance to attend the Chemnitzer Seminar in Fraunhofer ENAS, Chemnitz, Germany. This seminar is held annually as an exchange meeting between Fraunhofer ENAS, or in particular its Department System Packaging, and its collaborators. This year, Tanaka-sensei is one of the speakers, as the collaboration between Fraunhofer ENAS and Tohoku University has a long history.
The seminar starts at noon on 13th. It was opened by an opening speech by Dr. Maik Wiemer, the head of the Department System Packaging. He introduced the activities in the department, highlighting the achievement in during the past one year. He also introduced the Fraunhofer Project Center, which is a group within our laboratory under Froemel-sensei, in Sendai and its activities.
Chemnitzer Seminar 2017 opening remarks by Dr. Maik Wiemer.
The second speech was from Tanaka-sensei. He introduced research activities in our laboratory, highlighting the MEMS application for robotics development. Tactile sensor system and its large scale integration (LSI) sensor platform is offered as a solution for a high density sensor distribution for robots, which potentially leads to the higher level of human-robot interaction. A high performance whole angle gyroscope is also offered as a solution for the stability of robot movement.
Tanaka-sensei introduced our lab at the end of his presentation.
The focus of the Chemnitzer Seminar is in the current development of packaging technologies. It covers a wide area from the development of functional materials, deposition technologies, additive manufacturings, bonding technologies, trough silicon vias (TSV) and their applications for various purpose. From this seminar, I could get many insights, not only about the development of the technologies, but also some technical knowledge.
For instance, in a presentation by Dr. Anke Sanz-Velasco, IMT AG (Switzerland), I got to know about advanced glass processing techniques, especially glass patterning using oxygen rich Cr and HF dry etching. In another presentation by Mr. Hubner from Leibniz-institut (Germany), a technology to reduce the electron beam writing time with variable shaped beam is proposed. In his proposal, his team has demonstrated a time reduction from several years to several hours in an attempt to pattern a complicated design.
A trend of smart system for agricultural sector is also proposed by Dr. Woodhead from Lincoln Agritech (New Zealand). His proposal also included a call for collaboration to commercialize their work. It was very interesting to know that it is also possible to monitor the amount of N2 fertilized as well as soil moisture level to achieve a smarter irrigation system. These functions are realized by microwave sensor they developed.
There was also a presentation from Mr. Frank Roscher. He is one of two group leaders in the Department System Packaging of Fraunhofer ENAS who has received the Fraunhofer awards for his achievement in research as well as customer relation. I am actually working under his group during my stay. His main research interest is about the development of functional materials for microsystem packaging. And in this seminar, he introduced his work on the development of an aerosol jet printing technology to realize a 3D film membrane package. The package has a function as a security protection. When something penetrates the membrane, the security system will work, that the confidential data are kept safe.
Finally, the first day was closed by the presentation from Prof. Schulz about ongoing project in ENAS. The project is about a transportation card, which now is normally using the tap in tap out method. A new system which does not require tapping is proposed. The challenges are that everything, including sensors, actuators and power supply, have to be placed in a thin chip.
The second day starts from the morning with several presentations on the biomedical appications of smart systems. Biomedical equipments are often bulky and expensive, thus, only good hospitals have such facility. However, the idea of smart system using microsensors has fostered the idea of the development of wearables, or even implantable equipments. To realize that purpose, many researchers are working together. Of the devices developed are ultrasound assisted micro-endoscopy for diagnostic and therapeutics inside the human body by Fraunhofer ENAS, a wearable electroencephalogram (EEG) device developed by eemagine (Germany), and an optical sensor developed by Shinko (Japan).
There is coffee break for the participants and presenters to exchange ideas or build a network in the middle of each session.
Overall, I think it was a good opportunity for exchanging results, as well as opening new collaborations between institutes from various countries. For me, it was also another exposure to new technologies being developed around the world. The seminar has given me a new perspective of what kind of world that we are going to realize with the development of technology, in particular the smart systems’ approach.

On March 14, 2017, I went to Toyama University to join the IEEJ 2017 conference. After about 4 hours’ trip by Shinkansen, I arrived at my hotel near Toyama station at 5 pm.
At 5 pm, the sky was still bright and the weather was good. So, I took out my sport clothing and went jogging. My plan was running to the Gofuku Campus of Toyama University, checking the conference place and running back to my hotel. I am always afraid of getting lost in a university.
Along the way, I saw a lot of scenery,
beautiful Toyama Castle beside a lake,
and Toyama bridge.
I also saw the streetcar which is one of the characteristics of Toyama.
After a while, I reached the Gofuku Campus and saw the guide board for IEEJ 2017.
After checking the conference place, fortunately, it was easy to find, I run back to my hotel. Took a shower, ate noodles, watched TV, prepared my presentation and then went to bed.
Nice view, tired trip and good sleep.
The first day of the conference was nothing special. I listened to many presentations. Most of presentations were in Japanese. Thanks to my CASIO electronic dictionary, I can understand part of the contents.
On the second day, there were some special speeches including a speech about PlayStation VR. Although I forgot what the speaker talked about PlayStation VR, after listening to this speech, I planned to buy one. The following shows some pictures near the special speech place.
(Toyama Castle again)
On the evening of the second day, we had a social gathering meeting (懇親会). In this meeting, I met Muroyama-sensei and Nonomura-sensei, saw some wonderful Toyama special programs and ate a lot. The next day was my turn to make a presentation, so I needed a good sleep, but it was hard (I was nervous).
At 4: 30 pm the third day, finally, I finished my presentation. The speaking time was OK. I answered two questions, one from Nonomura-sensei and one from a person of Tohoku Electric Power. Thanks to the translation of Muroyama-sensei, I think the question session was also OK.
At 5 pm, the IEEJ 2017 conference ended. Then I went to eat the famous black ramen (noodles). It was delicious, but salty. I doubt the black soup was soy sauce.
After eating, I took the Shinkansen to go back. When I arrived at Sendai, it was almost 11 pm. That night I slept very well.
This three days’ conference gave me a wide view about electrical researches. And Toyama is a beautiful place to visit. If you have time, I suggest you to taste the black ramen of Toyama.
