芋煮会 2016

 こんにちは、B4の寺西です。2016年も残り1月半となり青葉山の空気もすっかり冷え込んで参りました。今回は10月に開催された芋煮会の様子について報告させて頂きます。

 今年の芋煮会はシーズンとしてはやや遅めの10月28日に開催されました。直前まで雨が心配されていましたが、当日は曇りで少し肌寒く、鍋物を食べるには丁度良い気候の下で始めることができました。ここで、初耳の方のために簡単に説明させていただきますと、芋煮会とは河原で鍋料理を楽しむイベントの事で、主に東北地方で秋の風物詩とされています。仙台でもこの時期になると牛越橋の近くで鍋を囲むグループをちらほらと見かけるようになります。

 鍋は山形風(醤油ベースで牛肉入り)と仙台風(味噌ベースで豚肉入り)、野菜オンリーの三種を用意しました。ここに里芋が共通して入っているのも芋煮の特徴の一つです。これらの準備をB4の学生が行い、田中秀治先生の挨拶から芋煮会を始めるまでがイベントの恒例になっています。

河原での調理なので窯には河原の石を使います。このシーズンだと他のグループさんの作ったものがそのまま残っていたりします。

芋煮会③
普段話す機会が少ないメンバーと交流を深めることができるのもイベントの魅力の一つです。
野菜オンリーの鍋も好評の様でした。

芋煮会①
B4の大柴さんからマシュマロが提供されたので石窯の余熱で炙りながらいただきました。
一部が焦げるとあっという間に広がるのでやってみるとなかなかに難しかったです。

芋煮会②
他のグループの方にお願いして集合写真を撮影していただきました。
こうしてみると様々な国籍のメンバーが一堂に会していることがわかりますね。

 今回のイベントでも沢山のメンバーから助力をいただきました。食材と鍋の運搬を引き受けてくれた森村君と大柴さん、準備と後片付けに協力して下さった先輩方にはこの場を借りてお礼申し上げます。どうもありがとうございました。

最後に、来年も良き芋煮日和に恵まれることを願います。

ジャパネットたかた・前社長・高田明さんの講演

第33回「センサ・マイクロマシンと応用システム」シンポジウムと第8回「集積化MEMSシンポジウム」が,2016年10月24~26日に長崎県平戸市で開催されました。初日の基調講演は,平戸市出身の株式会社ジャパネットたかた・前社長・高田明さんによる「夢持ち続け日々精進」というお話でした。時折,おなじみのフレーズを挟みながら,聴衆を魅了する素晴らしいお話をされました。要旨は以下の通りです。
The 33th Sensor Symposium and The 8th Symposium on Integrated MEMS Symposium were held in Hirado, Nagasaki. Keynote speech in the first day was given by Mr. Akira Takata, Founder of Japanet TAKATA, which is a TV shopping company familiar to all Japanese people. Hirado is his hometown. The title of his speech is “Always Have a Dream and Make the Best Effort”. The audience was strongly attracted by his talk and humor. The summary is as follows.

*****
いつも夢を持とう。私は67歳になっても,あと50年生きなければ思う程,夢がある。そして,今を一生懸命生きる。過去の失敗にくよくよせず,未来の不安に過度に気を揉まない。今が未来に繋がっていて,今が変われば,未来も変わる。今の努力がいつ結果に繋がるかはわからないが,決して無駄にはならない。
自分のやっていることを,他の人に伝えることが大切。伝わらなければ,努力は実らないし,社会に還元されない。たとえば,良い製品ができても,良さが伝わらなければ売れず,使ってもらえない。伝わるプレゼンテーションには技術が必要。話の間,手振り,視線が大切。
We should always have a dream. I am 67 years old but have dreams, which motivate me to live 50 years more. It is important to do the best at every moment. It is not productive to repeatedly regret the past fails and to be too much anxious about the future uncertainness. The present is connecting to the future, and thus you can change the future by changing the present. Your current effort eventually helps yourself, although no one knows when it comes.
It is important to let other people know what you are doing. Without it, your effort would yield nothing in the society. For instance, your good product is never purchased or used, if its benefit is not well explained. Effective presentation needs skill. Pause, gesture and eyeline are keys.

講演の後,当研究室の展示ブースの前で,高田さんとお話しする機会がありました(田中)。
After the session, I (Tanaka) had a chance to talk with Mr. Takata in front of the booth of our laboratory.

Future Technologies from Hirado

From Thao Pham, D1 student

33rd Sensor Symposium this year was chosen to hold in Hirado island where a beautiful and historic location full of interesting museums, Christian churches, white sandy beaches and an imposing castle in Nagasaki prefecture from 24th to 26th October.
Sensor Symposium has been the leading conference for the researchers in sensors, MEMS and their application systems in Japan with the long development since 1981. With the academic supports from Tanaka sensei and Yoshida sensei, I highly appreciated a great chance to attend this conference. Actually, it was more difficult to reveal how eager I was because it was the great opportunity not only to approach the other researches in the Japanese universities and Taiwan universities, but also to understand Japanese history.
The conference activity was started with the invited talks from the important professors, and welcome party. Introductions of young researchers from various universities was also interesting part in this party. In additional, follow the schedule of the conference, Japan and Taiwan International Exchange Symposium was also held with the attendance of famous professors in Japan and Taiwan. Key information for connecting and collaborating between Japan and Taiwan, in general, and between the particular laboratories also shared in this forum.
My presentation was on the first day of the conference, and I felt slightly nervous at the previous time before it happened. However, according on the tips and strongly encouragements from all sensei, Tanaka sensei, Yoshida sensei, and Suzuki sensei, I gave my presentation quite well.
On the last day, Awards in 33rd Sensor Symposium was announced. Yukio Suzuki sensei and coauthors was honored with Outstanding Technical Paper Award for "Fabrication of Deep TSV in Laser-Erased CMOS LSI Multi-Project Wafer for Surface Mountable Integrated MEMS" presented in IEEJ 33rd Sensor Symposium. The paper "Fabrication and Verification of a Stacked-Assembled Device with Seesaw-Electrode Type Tactile Sensor and Sensor Platform LSI" coauthored by Toyota Central R&D Labs, Toyota Motor and us was selected for Outstanding Poster Award in IEEJ 33rd Sensor Symposium. The top author was Hata-san at Toyota Central R&D Labs.

Beside on the conference time, I also had time for investigating the history and travelling to some famous places in Hirado. As searching before, the first place which I was chosen for visiting is Hirado Dutch Trading Post (平戸オランダ商館, Hirado Oranda Shōkan). This trading post was set up as the base of operations of Dutch East India Company in Japan in 1609 after De Liefde (charity), the first Dutch ship, to reach Japan in 1600. This trading post was reconstructed in 2011, and inside it is an excellent museum that chronicles the history of Japanese-Dutch relations and explains how international trade and commerce was conducted at that time. I also found a Dutch-Japanese lady there. And the second place, St.Francis Xavier Memorial Church was the next spot where I decided to visit. It is home to some interesting Christian churches dating back one hundred years or so. Anyway, I believe that you will find out another interesting thing on this beautiful island when you come there.
Once again, I would like to send my highly appreciation to the great supports from Tanaka sensei and Yoshida sensei for my opportunity to attend this conference. I think that I received many things from 33rd Sensor Symposium, such as new connections with other younger researchers from various universities, Tokyo university, Ritsumeikan university, etc.

金沢村田製作所仙台工場 見学会

D1の金子です。
10月17日に、研究室で金沢村田製作所仙台工場を見学してきました。
金沢村田製作所では、スマートフォンにも搭載されている弾性表面波(SAW)フィルタなどの高周波デバイスを中心に製造しています。SAWフィルタとは、通信時に受信信号から必要な信号だけを取り出す素子で、1台のスマートフォンに複数個搭載されています。村田製作所はSAWフィルタで世界No.1のシェアを誇っています。田中研究室でも、門田先生のグループが高速通信用素子を研究されており、非常になじみの深い技術です。今回の金沢村田製作所仙台工場の見学も、門田先生のご尽力により実現しました。

見学では、はじめに村田製作所の紹介があり、続いてSAWフィルタの製造プロセスの説明がありました。私も修士の時に弾性波共振子デバイスを作製していたので、なじみのあるプロセスでした。研究室では2センチ角のチップ上に、一から自分でデバイスを作製していましたが、SAWフィルタがどのように量産されているのかを見るのはとても興味がありました。

今回の見学では、金沢村田製作所仙台工場のご厚意で前工程プロセス(フォトリソ、蒸着、リフトオフなど)と、後工程プロセス(ダイシング、樹脂封止、検査など)を実際にクリーンルームに入り見せていただきました。ほとんどすべての工程でプロセスが自動化されており、ウェハ(またはデバイス)を装置に導入すればロボットハンドにより次々とプロセスが進んでいきました。検査工程も非常に高速で行われていました。装置の数も多かったですが、さらに装置の稼働率も非常に高い印象を受けました。ウェハロットごとに工程が管理されており、各プロセスの進捗具合が常時モニタリングされていました。

量産工程以外にも興味深いところがいくつかありました。作業中のヒヤリハットの共有は田中研究室でも行っていますが、仙台工場では見つけた人に表彰が送られていました。作業する人全員で問題を見つけていくことができる良いシステムだと感じました。また、従業員によるセミナーも積極的に開催されているようで、ポスターが貼ってありました。世界シェアNo.1の活気を感じました。こうした活動は研究室でも取り入れたいですね。

今回の工場見学では実際のSAWデバイスの量産工程を間近で見学することができ、とても勉強になりました。金沢村田製作所仙台工場の皆様、どうもありがとうございました。

Aloha-hello from Hawaii

The native language means “hello” and maybe it was the most commonly heard word in these days. When you speak out this word, if you put in the best enthusiasm, you will get the most correct way to pronounce it.
The ECS PRiME conference was held from 2nd to 7th, Oct. Fortunately I was given the chance to fly here and joined in. Froemel sensei also joined the meeting and really helped a lot not only on presentation but also the living and traveling.
I arrived in Honolulu, Hawaii, on 3rd Oct. It is interesting experience to fly across the International Date Line because it feels like time travel: I departed from Tokyo at 20:00 in 3rd, but after 7-hour fight the arrival time was 8:00 in 3rd. So it seems that I traveled to the past…www!
Leaving the airport to my surprise every signs I saw were written in both English and Japanese. Actually from airport to hotel, I didn’t speak one word of English and all I spoke was Japanese. The climate was also like Japan. So I understand why Hawaii is popular resort for Japanese people, and in fact it really is nice place. Beautiful beach, nice climate and enthusiastic people, all of these make it one of the best travelling choices.
Actually it was my first experience of joining academic conference. Everything was fresh to me. After the registration, I joined in the symposium. But then a problem bothered me: the time difference. I was so sleepy that once I just fell asleep as soon as I touched the chair! After several struggles, I gave up and paid $ 4 for a big cup of coffee. With the help of coffee, everything turned normal again….www.
My presentation was on 5th. I spent the whole 4th to practice. Fortunately before my departure from Japan, Hirano sensei and Froemel sensei gave me a lot of advice and we also prepared some questions that might be asked. Moreover the chairman of our symposium, Suga sensei was also a kind professor. So I could prepare well in advance. However, when the formal speech began, I was still so nervous. The more I felt nervous, the faster I spoke. And because I remembered everything fluently, I finished my presentation in just 8 minutes, comparing with the designated time of 15 minutes…囧. As Froemel sensei said every slide just flew by. And the questions raised by audience were not beyond my expectations so I could answer without pause.
Another surprise was the award for my presentation. Tell the truth, I didn’t expect for such award at all. Hereby I really appreciate Froemel sensei’s help about the award ceremony. I also thanked Prof. Suga for giving such award to me. The most important thing is the support from our teachers and lab members, Tanaka sensei, Hirano sensei, Froemel sensei and Kojima san, Salman san, Aihara san, Zhou san and everyone who helped in my project
As a whole, it was really nice experience to attend such nice conference. On the conference, I met some undergraduate students from China. It was surprised to me that they could have the chance at such young age. And I think that must be one of the best treasures in their future life. Many things can only be taught when you really have the experience. Only after you get the experience can you feel easy and mature for future academic communication. So everyone should work hard and communicate a lot with others as young as possible. That’s one of the things I learnt.
At last, I want to share some pictures with you, especially the sunset in Honolulu. Here I will thank Froemel sensei again, because he reminded me of the wonder sunset.
