Patent number: 10173257Abstract: A method of machining a screw is provided that is capable of preventing formation of a protruding section at a thread tip section. A thread is formed by cutting on a cylindrical body, and a surface of the thread is plastically deformed by rolling. Because of the cutting, a width between-side surfaces of a thread tip section is in a narrowed state as compared to a normal width. This width is narrowed toward a tip of the thread while a thread body section has a width expanded as compared to a normal width. Consequently, the side surfaces are formed to bulge by an excess thickness portion as compared to normal side surfaces. The rolling plastically deforms both side surfaces to cause the excess thickness portion to plastically flow toward the side surfaces.Type: GrantFiled: January 28, 2016Date of Patent: January 8, 2019Assignee: NITTAN VALVE CO., LTD.Inventors: Michihiro Kameda, Masaaki Inoue

A rim portion in a flush toilet includes a slit opening portion formed between an upper edge portion of the waste receiving surface formed to be left-right asymmetrical and a rim inside wall formed to be left-right symmetrical. The slit opening portion is formed such that a slit gap on one side, to which a connecting water conduit is directed, is smaller than a slit gap on the other side. A circulating flow is formed on the waste-receiving surface by flush water spouted from the slit opening portion having the different slit gaps.Type: GrantFiled: July 27, 2016Date of Patent: June 12, 2018Assignee: TOTO LTD.Inventors: Naoto Matsuo, Eiji Shiohara, Masaki Kitamura, Masaaki Inoue

Patent number: 9790822Abstract: With a poppet valve using a coolant, maximum combustion efficiency is realized by adjusting relative values of a heat insulation effect and a heat dissipation effect. From the inside of a head portion (14) to a stem portion (12) of a hollow poppet valve (10) a heat insulating space (S1) and a cooling portion (S2) loaded with a coolant (19), separated from each other by a partition (15), are formed. By properly setting an installation position and a vertical length of the partition (15) according to a type of vehicle for which the valve is used, appropriate heat insulation effect and heat dissipation effect are obtained. Further, by the partition (15), mechanical or thermal strength of the poppet valve in which the heat insulating space (S1) and the cooling portion (S2) are formed is increased.Type: GrantFiled: February 10, 2014Date of Patent: October 17, 2017Assignee: NITTAN VALVE CO., LTD.Inventors: Osamu Tsuneishi, Masaaki Inoue

Patent number: 9215829Abstract: In an electronic device, when a 48 V feed system is shifted to a 12 V feed system, in order to supply the same electric power, a current of fourth times needs to flow into a backplane. Also, in an anteroposterior intake and exhaust system, there is a need to form a ventilator through which a cooling air passes in the backplane. Further, there arises a problem that a mechanical strength is deteriorated by provision of the ventilator in the backplane. There is provided a structure in which a pinnate projection is provided on a feed bus bar, and a cooling air is applied to the feed bus bar. Also, the feed bus bar is brought into close contact with an overall surface of the backplane, and electrically and mechanically connected thereto at multiple points, to thereby perform both of cooling and the suppression of stiffness deterioration.Type: GrantFiled: October 26, 2011Date of Patent: December 15, 2015Assignee: Alaxala Networks CorporationInventors: Junji Baba, Masaaki Inoue, Shuuji Kameno, Toru Sasaki
