Patent number: 5968435Abstract: In a step of spinning a molten mesophase pitch in a process for manufacturing a pitch-type carbon fiber, the pitch is allowed to pass through an orifice and to be contracted once, is then expanded in an introduction port with a diameter greater than that of the orifice, and is then allowed to pass through an outlet pore formed at a collecting portion to spin the pitch. The pitch-type carbon fiber has a high elastic modulus in tension and high compressive strength.Type: GrantFiled: April 23, 1998Date of Patent: October 19, 1999Assignees: Nippon Steel Corporation, Nippon Steel Chemical Co., Ltd, Nippon Graphite Fiber CorporationInventors: Osamu Kato, Yoshio Kishimoto, Yutaka Arai, Hajime Nakajima, Masatoshi Furuyama, Tsutomu Kihara, Michiharu Harakawa, Shigeo Hara, Ken Kobayashi, Yoshiyuki Doken, Tsutomu Nakamura

Patent number: 5357069Abstract: A sliding switch having a tandem-type contact structure in which a first and a second insulation portion are disposed in a first and a second negative fixed contact, respectively, of a first and a second group of fixed contacts. When a first and a second movable contact slide between a neutral position and a first operating position, an arc is produced between the first movable contact and the first negative fixed contact in which the first insulation portion is disposed. When the first and the second movable contact slide between the neutral position and a second operating position, an arc is produced between the second movable contact and the second negative fixed contact in which the second insulation portion is disposed. A decline in the insulation performance between the fixed contacts of different polarities is prevented.Type: GrantFiled: November 2, 1992Date of Patent: October 18, 1994Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Minoru Nishio, Shigeo Hara, Masaru Suzuki, Kazuhisa Kubota

Patent number: 4264885Abstract: An electromagnetic relay which is so arranged that a plate spring having a movable contact and a fixed contact plate having a fixed contact are secured to a stopper member fixed to a heel piece for the electromagnet, with a lift pin of the plate spring being adapted to contact the moving iron, so that the pressure at the contacts and the gap between the contacts as well as the lowest working voltage are readily adjusted as desired by merely transforming the stopper member. Furthermore, since the movable contact is free from positional deviation, mutual erosion or cutting between the contacts due to uneveness of the contact surfaces arising from sparks and the like has been eliminated for positive closing or opening of the contacts.Type: GrantFiled: March 20, 1979Date of Patent: April 28, 1981Assignee: Kabushiki Kaisha Tokai Rika Deuki SeisakushoInventors: Shigeo Mizuno, Shigeo Hara, Kaneyasu Arakawa, Minoru Kondo
