Patent number: 6777453Abstract: The object of the present invention is to provide a method of reclaiming crosslinked rubber wherein a reduction of qualities due to generation of decomposed products hardly occurs, and a molding of reclaimed rubber. In a reclamation step of reclaiming crosslinked rubber 10 by applying shear stress thereto and/or in a subsequent step in the present invention, a degasification carrier is introduced and decomposed products in the crosslinked rubber 10 are removed together with the degasification carrier. Also the disclosed is a molding of reclaimed rubber prepared by re-crosslinking reclaimed rubber obtained by this method.Type: GrantFiled: May 3, 2002Date of Patent: August 17, 2004Assignees: Kabushiki Kaisha Toyota Chuo Kenyusho, Toyoda Gosei Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Mitsumasa Matsushita, Makoto Mouri, Hirotaka Okamoto, Kenzo Fukumori, Norio Sato, Toru Yoshida, Masahito Fukuta, Hidenobu Honda, Katsumi Nakashima, Tamotsu Watanabe, Yasuyuki Suzuki, Masao Owaki

Patent number: 5245346Abstract: An interrogation responder system composed of a transmitter stationarily mounted in a certain fixed place and a receiver mounted on a mobile object. The receiver on the mobile side starts the operation when a power is supplied to the entire circuit in accordance with a wake-up signal from the transmitter on the fixed side so as to modulate the electromagnetic signal emitted from the transmitter on the fixed side in accordance with a predetermined code and reflect a response. This enables continuing bilateral communication of a command, data and so forth. By starting communication between the transmitter and the receiver by a direct wave of a carrier signal in a microwave band after sensing that the receiver on the mobile side has entered a good communication zone, secure communication is enabled at a sufficient electric field strength.Type: GrantFiled: August 28, 1991Date of Patent: September 14, 1993Assignees: Kabushiki Kaisha Toyota Chuo Kenyusho, Toyota Jidosha Kabushiki KaishaInventors: Yoshihiro Nishimura, Kazuhiro Kozuka, Hidehiro Tomioka, Shin Yamamoto, Norikazu Ohta, Yoshihisa Harata, Souichi Isikawa, Takehiko Okuda
