Patent number: 7611068Abstract: A device is provided to prevent the autorotation of the temperature adjustment handle in an automatic hot and cold water mixing valve. A member is prevented from moving in the circumferential direction of the body and is pressed in the radial direction by a spring against the periphery of an adjusting screw receiver, which forms the rotation shaft of the temperature adjustment handle incorporated in the body. Alternatively, the member is dressed against a connecting sleeve connected to the adjusting screw receiver and the temperature adjustment handle. The member is pressed with sufficient force to oppose autorotation in the temperature adjusting handle when the temperature is set.Type: GrantFiled: July 13, 2006Date of Patent: November 3, 2009Assignee: Nippon Thermostat Co., Ltd.Inventors: Shigeru Iwai, Takeshi Hagiwara

Publication number: 20080318824Abstract: It is an object of the invention to provide a hair cleanser that has a high cleansing effect on hairdressing preparation and can provide smoothness to the hair. A hairdressing preparation cleanser comprising: (a) a component with the IOB value of 0.6 to 1.5; (b) a cationic polymer; and (c) a sequestering agent. It is preferable that said component with the IOB value of 0.6 to 1.5 is one or a combination of more than one selected from the group consisting of random alkylene oxide derivatives, and said cationic polymer is one or a combination of more than one selected from the group of starch hydroxypropyltrimonium chloride, cationized hydroxyethyl cellulose-2, polyquaternium-39, and polyquaternium-7. It is preferable that citric acid and triethanolamine are additionally contained.Type: ApplicationFiled: June 14, 2005Publication date: December 25, 2008Inventors: Shigeru Iwai, Keiichi Uchikawa

Patent number: 5743463Abstract: The body of an automatic water combination faucet has, as separate parts, an outer cylinder with the cylindrical wall thereof having assembling hole portions for assembling connectors connected to the hot water, water and combination water lines and an inner cylinder housing accommodating a mixing valve unit. The inner cylinder housing is formed by casting or the like, and has, as integral and continuous parts, a main portion accommodating the mixing valve unit, a passage-defining portion in the form of a line for leading hot water to the main portion, and a passage-defining portion in the form of a duct line for leading out combination water. A separate cap which surrounds an adjustment screw unit of the mixing valve unit is engagedly coupled to the main portion.Type: GrantFiled: February 3, 1997Date of Patent: April 28, 1998Assignee: NTC Kogyo Kabushiki KaishaInventors: Yuseki Ueno, Shigeru Iwai, Katsumi Matsuzawa

Patent number: 4570078Abstract: A switch assembly for an electric system for a motor vehicle such as a motorcycle including an ignition circuit and a starting motor circuit. A first switching member is disposed in the ignition circuit for controlling an operation of a ignition system. A second switching member is disposed in the starting motor circuit, for controlling a current for a starting motor. An interrelating member is provided between the first and second switching members so that the first switching member is necessarily switched to a switch position for actuating the ignition system when the second switching member is operated to actuate the starting motor.Type: GrantFiled: May 26, 1983Date of Patent: February 11, 1986Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Michio Yashima, Shigeru Iwai, Masashi Hirose
