Patent number: 9850963Abstract: A coil housing has an inner ring, which is shaped into an annular form and is placed on an inner side of an electromagnetic coil in a radial direction of a rotational axis. A thermal fuse is placed on an inner side of a coil inner peripheral end of the electromagnetic coil in the radial direction, so that the thermal fuse can be placed in such a manner that the thermal fuse does not limit a length of the electromagnetic coil in a direction of the rotational axis by using a radial thickness of the inner ring that is indispensable as a part of a structure of a magnetic circuit. Thus, it is possible to sufficiently limit occurrence of limiting of a size of the electromagnetic coil that is caused by the placement of the thermal fuse.Type: GrantFiled: February 20, 2015Date of Patent: December 26, 2017Assignee: DENSO CORPORATIONInventors: Toshihiro Konishi, Yoshinori Fukumura, Yasuo Tabuchi

Publication number: 20060245936Abstract: Vulcanizing-bonding is carried out using at least a phenolic resin-based vulcanized adhesive F and a silicon compound-based vulcanized adhesive C. Based on an idea of making a penetration of water through a portion bonded with metal difficult, decreasing the adhesion with metal is prevented by utilizing the phenolic resin-based vulcanized adhesive F through which less water can penetrate than the silicon compound-based vulcanized adhesive C, and can increases a thickness of a membrane. Thereby, EPDM or AEM vulcanizable with a peroxide can be strongly bonded to metal, by forming a two-layered structure of the phenolic resin-based vulcanized adhesive F and the silicon compound-based vulcanized adhesive C. Further, a range of selecting a rubber material as an elastic member to be utilized by bonding to metal can be broadened.Type: ApplicationFiled: March 21, 2006Publication date: November 2, 2006Applicant: DENSO CORPORATIONInventors: Haruhisa Shibata, Yasuo Tabuchi, Michiyasu Nosaka, Toshihiro Konishi, Yoshiki Tada

Publication number: 20030217698Abstract: A reactor for generating plasma is provided in a vacuum chamber. The reactor has an opening in the direction of a supporting portion for a deposition base material, and the reactor includes an outer housing and a cylindrical inner wall structure that is inserted in the outer housing and is freely attachable and detachable to and from the outer housing. The cleaning of the reactor is performed with respect to the cylindrical inner wall structure that is simpler in structure than the outer housing, and hence the reactor can be cleaned reliably and with ease, thereby making it possible to improve the operational efficiency and the yield rate. The problem of prolonged operation time resulting from the cleaning of the reactor in a plasma chemical vapor deposition apparatus is thus resolved.Type: ApplicationFiled: May 14, 2003Publication date: November 27, 2003Inventors: Ryoichi Hiratsuka, Taketoshi Sato, Takashi Watanabe, Toshihiro Konishi
