JSSE holds the 1st International Conference on Spring Technologies
Dec. 11, 2015
As a local committee of International Committee for International Conference on Spring Technologies,
Japan Society of Spring Engineers (JSSE) held the 1st International Conference on Spring Technologies(ICST-1), including a welcome reception, a poster session and an exhibition at Meiji University andAkihabara UDX in Tokyo on November 16th through 18th.
Welcome Reception
Welcome Reception was held at Miyagi Kozo Hallin Liberty Tower on the Surugadai Campus of Meiji
University on Nov. 16. The opening speech waspresented by Mr. Mark Hayes, the proprietor ofSpring Expert in U.K. Mr. Isao Kato, a member ofthe local committee and working for Japan Spring
Manufacturers Association (JSMA), performed
Rakugo, Japanese traditional comic storytelling,and magic to entertain 73 attendees.

Oral Session
On Nov. 17, fifteen general lectures and one special
topic lecture were presented to 161 attendees from 7
