 Firstly, I would like to highly appreciate the chance of an internship in Kyocera Company, which is one of the most developing companies in Japan with the long history. Kyocera’s global operations deliver a diverse range of products, including advanced materials, components, devices, equipment, network engineering and other services. Therefore, I believe the position in Kyocera internship summer is excellent chance to supplement and develop my technically skills which I have learned from the university. Additionally, I was very curious the working style in Japanese companies and their successes. As the expected things, I was highly motivated to join the summer internship in such a company, like Kyocera.

 After 10days of the internship, “More than expected things” was only the expression which I could say. In Kyocera, I worked in R&D Center-Keihana under the elaborate and patient guidance of the great leader with his perfect team. The working time at the company is from 08:45 to 17:30, everyone work hard, strictly, and efficiently. Especially, I was really impressed because all staff always gave me their warm smiles with the expression “otsukaresama desu”. It was great because I felt recognized as a part of the company, even I just stayed in Kyocera Company only 10days. In R&D Center-Keihana, I had many opportunities to learn a lot with the help of all lab members, and present my opinions for developing the project which I joined. On the other hand, all the staff always supported me not only in the work but also in the day life. After working time, everybody usually encouraged me to speak Japanese language and we enjoyed the traditional dishes and visited the best sightseeing spots in Kyoto and Nara including the Kinkakuji Temple, Nara Park, Todaiji Temple and more.

 The internship time, 10 days, passed much faster than thought. The final day of my internship has been coming, I shown a presentation in front of the members of the group. In spite of short internship time, I hope that my researching results would positively contribute to the project of Kyocera Company

 A message to the other student, I think that Kyocera company is one of the best companies to pursue the further research of young researchers after graduating because of their professional and favorable atmosphere of research in the hands-on facilities. Finally, I would like to send my deeply thanks to Kyocera company for offering this great internship and warmly appreciate Prof. Tanaka, and Assoc. Prof. Yoshida for strongly supporting my internship. I wish that Kyocera Company will become more and more development and success in the future.

 Below are some nice pictures during my internship in Kyocera Company.

Review of kiso zemi

Written by Liu Cong of D1
In past 10 weeks, if you asked me what I would do on Monday, my answer would be the kiso zemi. Yes, as teaching assistant (TA), I joined in this class given by Prof. Tanaka.
It is my first experience of being TA, so actually I was a little nervous before the first lesson. I don’t know what I should do for the lesson. Fortunately Prof. Tanaka explained patiently to students and me about the aims of the lesson so that all of us have a clear goal in my mind. The 6 students were also kind and friendly. To my surprise, most of them had the experience living abroad (it is a little strange for me to say the word “abroad”, www. Here I mean the countries outside Japan). So we were able to develop dialogue in extensive perspective.
What was much more important was the active participation of every speakers of our lab. The first speech lesson was given by Neelam san, Chand san and Salman san. They brought elaborate slides and opened a brand-new world to the students and me. For me, the diverse islands in Indonesia and also the diverse culture in India impressed me most. It made me feeling they are great countries because of the inclusivity. These speakers gave good starting point of kiso zemi.
Subsequently Froemel sensei, Tanaka san and Kaneko san gave the second lesson. Of course the theme was Germany. The German education system introduced by Froemel sensei made me think a lot, especially when I compared it with Chinese current one. I really think it may be better idea for China inducing some kind of German education rules. However, perhaps for the students, the Japanese views about Germany from Tanaka san and Kaneko san were more practical. These advices were really important for the B1 students for them planning their life.
The third lesson was given by Wang san, Zhou san, Sun san and me. We introduced again China to Japanese students. I say “again”, because as we know, the Japanese and Chinese cultures share too many common points. But we tried show some new things presently happening in China. I didn’t know whether speech information was enough but I was sure that it helped Japanese students recognize a developing China.
At the beginning of the fourth lesson, Hayasaka san joined our zemi via Skype from UC Berkeley. He gave a nice speech about his life course and his present life in America. His tortuous and excellent life impressed everyone in the classroom. Hayasaka san overcame all of any difficulties and his valued experiences inspired all of us.
After Hayasaka san’s speech, we had the “ladies’ meeting”. Three excellent female speechers, Nguyen san, Assila san and Thao san, gave enthusiastic reports about their own countries. Vietnamese delicious food and Moroccan beautiful sceneries gave me a great impression. After their introduction, I really begin to plan the tour to these countries.
Not only I but also all the students absorbed massive knowledge and broadened the view. At the last lesson, students shared their gains through presentations. Everyone thought highly of these experiences.
During the whole above process, Tanaka sensei provided elaborate and patient guidance. Here I appreciate for Tanaka sensei’s giving me such a chance as TA. I also must say thanks to every speaker for their perfect work. Thank you very much. Below are some pictures during the zemi and I am sorry for only few pictures (not including all speakers).


IFCS 2016 held in New Orleans

    The story began few billion years ago, two black holes orbiting around each other started converging till they finally merged together, creating a unique black hole. The difference in energy between the prior and post-merger states created a ripple in the space-time frame that propagated in space as a gravitational wave (GW). In the meantime, following the theoretical prediction of GWs, scientists all over the world were enticed to design systems that could detect them. One of the detecting facilities was almost completely built by 1997: the laser interferometer gravitational wave observatory (LIGO). It has an L-shaped interferometer, with 4 km arms connecting the beam splitter to the mirrors maintained in constant vacuum. While for years, no acquired measurements led to the detection of GWs, improvements were introduced to the system in order to improve its sensitivity, that now is in the order of 1/10 000th the proton diameter.
    On the second half of last year, only three days prior to the switch of the LIGO from the engineering mode to the research mode, a chirp signal of 0.2 seconds has been detected. Further analysis proved that this signal was in fact created by the previously mentioned GW. However, from now on, detecting GWs won’t the social phenomenon it was the first time anymore. For indeed, the next detected GW on December 26 went almost invisible. While the detection of the first GW proved the existence of GWs, this isn’t the only reason it was grand at least not for the people involved in the LIGO team. It is impressive for being the fruit of years of small improvements in various fields (mechanics, optics, electronics, …) done by a number of people at a time when a finish line wasn’t visible yet.
    Previously this year, I had the chance to join the International Frequency Control Symposium in New Orleans, visiting the LIGO facilities nearby and assist to the talks of some of the people involved in the LIGO project. The scope of the conference was quite large, for it dealt with theoretical aspects as well as practical ones and from the nanoscale to the light-years scale. This year happened to be also the 50th anniversary of the Allan variance, so special sessions regarding the subjects were held. The host city was a very stimulating one from a cultural point of view, with its historical heritage as well as the heavy presence of museums, galleries and artistic venues.
    However, while the city of New Orleans is quite interesting and the different given lectures during the symposium were thought provoking, the most inspiring part was seeing how long can collaborative work spiced up with tenacity and perseverance go.
