[ President's Message: ]

Masao Hayakawa   The Japan Society of Spring Engineers (JSSE) is an academic society consisting of corporate members such as spring manufacturers, spring material manufacturers, spring-related equipment manufacturers, spring users etc. and individual engineers working for those companies and researchers interested in spring technologies. The number of members is about 500, including over 100 corporate members and overseas members residing in three different regions in the world: Asia, EU and North America.
  JSSE started its activities in 1947 and has been contributing to the improvement and development of spring technologies in Japan since then, having a close cooperative relationship with the Japan Spring Manufacturers Association (JSMA). JSSE mainly contributes to academic matters, whereas JSMA contributes to industrial matters.
  We have three activity policies as follows:
(1) To afford our members assistance with their R&D activities
(2) To provide even better services to our members
(3) To promote the internationalization of the members' activities
 We have steadily implemented these policies and contributed to the improvement of spring technologies in Japan and will continue them in order to assist our members in improving their spring technologies.
 In addition to these policies, we added the following new policy in order to transmit knowledge and technologies to the next generation of young and high-caliber human resources for the sustainability of the growth of spring and spring-related industries:
(4)To provide practical training to young engineers/ technicians (individuals or teams)
 In concrete terms, we hold technology exchange meetings for young engineers where they can accumulate and apply fundamental knowledge about spring and spring-related technologies. We also hold seminars where young engineers and researchers or students can exchange technological information with retired engineers who have a lot of experience and knowledge so that they can inherit core technologies and recognize important issues that need to be solved.
 We hope that companies engaged in spring and spring-related industries, universities, institutes and individual researchers or students who are researching spring or spring-related technologies join our society and participate in the improvement of spring technologies.
 We are looking forward to seeing you in our activities.

[ Proposition of establishment and brief history: ]

The study of springs in Japan had been done by related companies and research organizations since the pre-world war II. However, after the war, the time became ripe to promote cooperative research for the purpose of comprehensive advance in spring technology. JSSE was established on September 27, 1947 with the help of JSMA (Japan Spring Manufacturers Association), JASO (Japan Automobile Society), and JRIA (Japan Railroad Industry Organization). Since its establishment, JSSE has been working to promote research study of spring technology and the standardization of research results. In 1985, individual membership was introduced to cope with more demanding tasks of new material developments, new manufacturing technology and other related projects. Recently, change and evolution in the spring industry has become so aggressive that JSSE has come to the conclusion that the definition of spring in studies shall be expanded to "a machine element which utilizes restorable force against deformation regardless of material or shape." On the other hand, a corporate membership was introduced in 1997 to become independent from JSMA, which had been helping JSSE in financial affairs. Under this new system, JSSE would endeavor to be an organization to promote engineering and academic research in springs and peripheral issues accepting membership widely from companies both domestic and international.

[ Purpose and business: ]

The purpose of JSSE is dedication to the development of academic research and industrial research for springs. To achieve this goal, JSSE provides the forum for discussion and exchange of opinions through gatherings of scholars, engineers, manufacturers and users. In addition, benefits associated with membership will be fulfilled by providing the opportunity for these gatherings. The annual event plan is as follows:

JSSE monthly bulletin
Starting in October 1971, the Monthly Bulletin Committee has published a small newsletter style bulletin. The JSSE bulletin plays an important role in keeping members up to date. It covers event schedule, committee activities, a summary of seminar papers, member news, informative tips as well as patent information for its member engineers.
The JSSE bulletin is distributed electronically to all members who have an e-mail address and is also sent by mail to members who prefer paper.
JSSE Transactions
JSSE Transactions is published annually and is circulated to members as well as overseas to affiliated organizations. It includes papers from members, collaborative research reports as well as papers from its fellow organization like SMI (Spring Manufacturers Institute) in the U.S. for example. In return, some of JSSE articles are translated and appear in their magazine.
Specialty books on springs have been published since the1960s.JSSE is an innovator among spring research groups throughout the world in this type of activity. Books including articles on spring-type and application, spring materials, design methods and manufacturing process written by engineers active in the spring industry have been published. Booklets which provide a brief introduction to the key points in manufacturing springs, the types of springs by use, etc. have also been published.
Event planning
Conferences and workshops are being held on a regular basis for the benefit of individual and corporate JSSE members. A liaison officer for international affairs monitors recent globalization trends. The Event Planning Committee is developing an annual schedule of events and there are five other committees coordinating related JSSE activities.
*Hosting conference:
Researchers from spring manufacturers as well as universities participate in the JSSE semiannual Conference on Springs and the Application of Restoring Force Mechanisms. Certificates are awarded for outstanding work in a ceremony at the fall conference. An exhibition on spring technology and a social gathering are being held simultaneously.
*Sponsoring workshops:
An informative gathering is being held in order for engineers and researchers to improve their skills. Overseas events are being planned as well.
*Sponsoring seminars:
Seminars for advanced technology and/or fundamental skills are being offered to foster young engineers in JSSE member companies.
*International affairs:
A team has been appointed to handle incoming correspondences from fellow organizations in overseas countries. The team is also in charge of public relations in foreign countries.
*Study meetings:
JSSE provides members who have an interest in the same research theme a gathering place to study the theme freely and also gives opportunities to members for addressing various challenges on their own initiative.
Designated research committee
There are standing research committees and special research committees (normally biennial) in the JSSE organization. The Research Planning Committees is always active in seeking new research subjects. Special research committees including Research on Delayed Crack of Springs and Research on Sag of Compression Springs under Elevated Temperature are active.
Collaboration research
Since JSSE members consist of customers, manufacturers, design engineers, and material suppliers, wide-ranging cooperative studies from advanced technologies to the fundamental themes desired by smaller enterprises are being provided. Executing tasks requested by JSMA (Japan Spring Manufacturers Association) serves the entire spring sector including small spring businesses.
Subcommittee meeting
A subcommittee meeting, the application of restoring force mechanism, has been established for spring engineers, researchers, and users to cover springs and their associated technologies. Sharing a broad range of knowledge, the group gathering provides a common ground to seek new application technologies.
Paper award and Meritorious award
Our award will be given to those who contributed in developing spring technology and devoting themselves to JSSE activities. The award presentation started in 1968 in commemoration of the 20th anniversary. Since then, the Ronbun-syo (Supreme paper award) and the Gijyutsu-syo (Excellent paper award) are presented to the superior work at our fall conference every year. Starting from 1990, the Koseki-syo (meritorious award) was established for members that made outstanding contributions to JSSE.
International communication
JSSE welcomes foreign members. In 2007, the JSSE 60th Anniversary International symposium was held in Nagoya Japan. JSSE papers have been published in SPRINGS, the SMI Magazine. These are some examples of our international activity.
