Study of auto-disassembly system using shape memory materials

In the fiscal year of 2000 through 2002, we were engaged in the study of auto-disassembly systems using shape memory materials as a theme of study commissioned by MSTC (Manufacturing Science and Technology Center), one of the extra-governmental organizations of MITI (Ministry of Economy, Trade and Industry). The goal of the theme was to report the results of the study to MITI (MSTC) and release developed technologies to the public. In February 2003, we made a demonstration of aggressive disassembly models for disassembly by heating in the factory of Riken Hatsujo Kogyo Co., Ltd. (a spring manufacturer in Osaka), inviting representatives of other companies and university personnel concerned. In this paper, we introduce the results of the study along with our outlook for the future.
