Patent number: 4698122Abstract: A method for selectively diffusing impurities such as zinc into the substrate of a compound semiconductor such as gallium arsenide (GaAs). The method makes use of a diffusion mask in such a manner that the thickness of the oxygen-containing layer at the interface between the diffusion mask and the semiconductor substrate is less than 20.ANG. so that the abnormal transverse diffusion that would otherwise occur at the interface in the vicinity of the opening of the diffusion mask on the semiconductor surface is suppressed. The result is an increased accuracy in the diffusion pattern of the impurities.Type: GrantFiled: November 27, 1985Date of Patent: October 6, 1987Assignee: Sony CorporationInventors: Masaru Wada, Yoji Kato

Patent number: 4417550Abstract: An engine preheating apparatus in which an actuation circuit for a glow plug mounted in the engine is provided with a starting resistor of barium titanate of which the resistance value abruptly increases at a specific temperature, and a normal-operation resistor connected in parallel to the starting resistor. When the starting resistor is low in temperature and hence has a small resistance value, a large current is supplied to the glow plug, whereas when the starting resistor is high in temperature and therefore has a high resistance, a comparatively small current is supplied to the glow plug through the normal-operation resistor. The starting resistor is comprised of plural resistor elements of barium titanate as a main component and plural electrode plates alternately pressed one on each other. Each of the electrode plates is in pressure contact with each of heat radiators, so that the heat generated by the resistor elements is radiated from the radiators through the electrode plates.Type: GrantFiled: August 21, 1981Date of Patent: November 29, 1983Assignee: Nippon Soken, Inc.Inventors: Akihiro Kobayashi, Masashi Kida, Novuei Ito, Yoji Kato

Patent number: 4363958Abstract: A parallel circuit of an ordinary resistor exhibiting an ordinary resistance characteristic and a starting resistor abruptly increasing its resistance at a certain temperature is inserted between glow plugs in a Diesel engine and a battery. The resistance of the starting resistor is smaller than that of the ordinary resistor at a normal temperature. The resistance of the starting resistor becomes larger than that of the ordinary resistor when a large amount of current flows through the starting resistor. Therefore, current flows from the battery to the glow plugs mainly through the starting resistor at first, and then it flows mainly through the ordinary resistor. The ordinary resistor is disposed in an intake air passage of the engine.Type: GrantFiled: January 26, 1981Date of Patent: December 14, 1982Assignee: Nippon Soken, Inc.Inventors: Akihiro Kobayashi, Masashi Kida, Yoji Kato

The resistance of the starting resistor is smaller than that of the ordinary resistor at a normal temperature. The resistance of the starting resistor becomes larger than that of the ordinary resistor when a large amount of current flows through the starting resistor. Therefore, current flows from the battery to the glow plugs mainly through the starting resistor at first, and then it flows mainly through the ordinary resistor. A voltage drop of the battery due to engine starting is prevented by bypassing the parallel circuit by a resistor. Preferably, the starting resistor is of honeycomb shape.Type: GrantFiled: October 9, 1980Date of Patent: March 2, 1982Assignee: Nippon Soken, Inc.Inventor: Yoji Kato

Patent number: 4287862Abstract: In the ignition system of the internal combustion engine, a preignition control circuit is further provided. The preignition control circuit includes a high voltage generator which supplies a high voltage to the spark plug to produce a preignition spark between the electrodes of the spark plug. The preignition spark is timed to appear as the engine nearly concludes its suction stroke so that radicals are produced from the air-fuel mixture around the electrodes thereby to ensure reliable ignition and complete burning of the air-fuel mixture.Type: GrantFiled: September 29, 1978Date of Patent: September 8, 1981Assignee: Nippon Soken, Inc.Inventors: Masaaki Noguchi, Taro Tanaka, Yoji Kato
