Patent number: 8904999Abstract: A resin gear has a concave portion formed on a gear body at a position radially inward of a boundary region between a toothed portion and a non-toothed portion. During a molding process, a welded portion is formed at the non-toothed portion by merger of flow of the molten resin along a first path and flow of the molten resin along a second path. The first path detours the concave portion and passes through the side of the toothed portion, and the second path detours the concave portion and passes through the side of the non-toothed portion.Type: GrantFiled: September 3, 2010Date of Patent: December 9, 2014Assignee: Aisan Kogyo Kabushiki KaishaInventors: Masanobu Kondo, Hiroki Shimoto, Hiroshi Tanimura

Patent number: 8448627Abstract: An electronically-controlled throttle valve control device may include a coil spring that is engaged with a throttle body and a rotating body to bias a throttle valve in a fully opening direction and a fully closing direction, a spring guide that is provided to the rotating body and is capable of supporting the coil spring from inside, and an opener member that is provided to the rotating body and is biased by the coil spring in the fully opening direction or the fully closing direction. The coil spring includes a first coiled portion that is capable of biasing the throttle valve in a first direction, a second coiled portion that is capable of biasing the throttle valve in a second direction, and an intermediate coiled portion that is positioned between the first and second coiled portions. The coil spring is formed such that a central axis of the intermediate coiled portion is displaced radially outwardly relative to a central axis of the first coiled portion.Type: GrantFiled: September 3, 2010Date of Patent: May 28, 2013Assignee: Aisan Kogyo Kabushiki KaishaInventors: Masanobu Kondo, Toru Sakurai, Atsushi Tanaka

Patent number: 7472681Abstract: A throttle valve unit is disclosed that includes a main body having a cylinder portion defining a fluid passage. The main body also includes a fastening portion projecting from an outer peripheral surface of the cylinder portion for fastening to a separate member. The cylinder portion defines an axis. The throttle valve unit also includes a throttle valve that is rotatably supported by the cylinder portion for opening and closing the fluid passage. The throttle valve is supported by the cylinder portion at a support area. The fastening portion is provided at approximately the same axial position relative to the axis as the support area of the throttle valve and includes a plurality of mounting portions for coupling to the separate member and a plurality of connecting portions extending between the mounting portions.Type: GrantFiled: April 16, 2007Date of Patent: January 6, 2009Assignees: Denso Corporation, Aisan Kogyo Kabushiki KaishaInventors: Hiroshi Tanimura, Atsushi Tanaka, Masanobu Kondo

Publication number: 20080053401Abstract: A throttle device includes a resin throttle body having a bore and a throttle valve placed in the throttle body to open and close the bore. The throttle body is formed of a valve part that includes the throttle valve and a duct part that does not include the throttle valve. The valve part and the duct part are formed separately and coupled to each other. A heater and a metal collar are attached to the valve part and the duct part.Type: ApplicationFiled: August 29, 2007Publication date: March 6, 2008Applicants: AISAN KOGYO KABUSHIKI KAISHA, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masanobu Kondo, Akihiro Kamiya, Tsutomu Miyazaki
