Patent number: 7199710Abstract: A controller enabling switching between a smart function and an immobilizer function without using a key cylinder or a slot. The controller includes a verification ECU for transmitting a request signal to a first area and transmitting a transponder drive radio wave to a second area. The portable device transmits an ID code signal in response to the request signal or the transponder drive radio wave. The verification ECU enables the starting of an engine when the ID code transmitted from the portable device matches an ID code of the controller. The verification ECU transmits the drive radio wave when a driver operates a switch in a state in which the starting of the engine is not enabled after the request signal is transmitted.Type: GrantFiled: June 2, 2004Date of Patent: April 3, 2007Assignees: Kabushiki Kaisha Tokai Rika Denki, Seisakusho & Toyota Jidosha KabushikiInventors: Takayuki Hiramitsu, Masayuki Kawamura, Kiyokazu Ohtaki, Yoshihito Mizuno, Hiroyasu Hasegawa, Daisuke Kawamura, Toshikazu Mizutani, Tomoyuki Funayama, Teruya Tomiyasu, Koji Iwamoto, Noriyasu Onishi

Patent number: 5985181Abstract: There is provided a semiconductive resin composition comprising the following components (A), (B), (D) and (E):(A) 5 to 100 parts by weight of a modified ethylene copolymer obtainable by subjecting an ethylene copolymer (a1) and a vinyl monomer (a2) to graft polymerization conditions,(B) 0.5 to 15 parts by weight of an unsaturated silane compound,(D) 10 to 110 parts by weight of carbon black, and(E) 0 to 95 parts by weight of an ethylene copolymer, provided that the amounts of the components shown above are based on 100 parts by weight in total of the components (A) and (E),wherein the component (B) is incorporated into the composition by subjecting the component (B) to melt graft reaction together with the component (A) and/or component (E) in the presence of 0.Type: GrantFiled: February 9, 1998Date of Patent: November 16, 1999Assignee: Mitsubishi Chemical CorporationInventors: Yoshie Yoshida, Toshikazu Mizutani, Masaki Kitagawa, Jichio Deguchi

Patent number: 5975963Abstract: A female terminal has a structure that does not allow molten solder to close a pipe section into which male terminal is inserted. Notched recessed sections (9) are oppositely formed at the lower ends of the side faces (3a and 3a) of a female terminal (1). The female terminal (1) is locked by horizontally opening locking legs (7) protruded from the rear surface of a printed wiring board (11) from an inserting hole (12). In such a state, the rear surface of the board is dipped in molten solder (21). When the board (11), is pulled up from the molten solder (12), the solder (21) closing the pipe section (2) in a bridge-like form is turned to droplets and drops from the recessed section (9), because the wettability of the pipe section (2) with the solder (21) is lowered and the adhesion is weakened due to the recessed sections (9). The remaining molten solder (21) attaches to the peripheral edge of the end of the pipe section (2) other than the recessed sections (9) due to the surface tension and solidifies.Type: GrantFiled: June 26, 1998Date of Patent: November 2, 1999Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Mitsutoshi Higuchi, Toshikazu Mizutani, Satoru Imaeda, Yasuo Miyake, Takehiko Niwa, Haruo Shimura
