Program of IS-EMD 2002


International Session on Electro-mechanical Devices 2002 (IS-EMD 2002)

(Program)

November 14-15, 2002

Yagami Campus, Keio University, Yokohama Japan

Dear participants

It is our great pleasure to have the second IS-EMD with eight invited lecturers this year.

Last year the first conference was successfully held at Akita, organized by Prof. Inoue, which was a good opportunity to exchange updated information among participants including five invited lecturers, three from oversea and two from domestic in the EMD field.

Our economical and industrial situations have been dramatically changing. Under such circumstances Japan more and more needs to be globalized in economical and industrial systems, no exception for our EMD filed. Fortunately we have the IEEE Holm conference and ICEC (International Conference on Electrical Contacts) from international viewpoints.

We hope that the IS-EMD2002 will contribute to promote the exchange of international information in this field, especially for Asian and domestic researchers.
