Patent number: 8721855Abstract: A crimp contact, a gas sensor including the crimp contact for outputting a signal from a sensing portion of a sensor element to an external device, and a method for manufacturing the crimp contact. The crimp contact includes a barrel portion crimped so as to fix a plurality of lead core wires (16) of an electrical lead connected to the external device. A hold portion constituting the barrel portion is formed such that the lead core wires 16 of the electrical lead are disposed in an U-shaped hold portion 77 so as to be crimped between an anvil 120 and a crimper 121. An outer surface of the U-shaped hold portion 77 has a plating layer 85 thereon to thereby constantly secure slidability between a sliding face of the crimper 121 and the outer surface of the U-shaped hold portion 77.Type: GrantFiled: November 29, 2006Date of Patent: May 13, 2014Assignee: NGK Spark Plug Co.

Patent number: 8715135Abstract: A control device for a hybrid vehicle automatic transmission. A friction engagement element control unit includes a first play elimination control unit that sets a first pressure as the pressure for a first set time where the predetermined friction engagement element is engaged using a hydraulic pressure from the electric oil pump in a travel state in which only the rotary electric machine serves as a drive source. The first play elimination pressure is lower than a play elimination pressure for use in the case where the predetermined friction engagement element is engaged using a hydraulic pressure from the mechanical oil pump in a travel state in which the internal combustion engine serves as a drive source.Type: GrantFiled: March 18, 2013Date of Patent: May 6, 2014Assignee: Aisin Aw Co., Ltd.Inventors: Yosuke Ueda, Masahiro Asai, Kazuhiko Motodohi, Yoichi Tajima

Publication number: 20130260955Abstract: A control device of a hybrid vehicle including an engine; an automatic transmission placed on a power transmission path between the engine and wheels, having a first friction engagement element engaged in a forward range and a second engagement element engaged in a reverse range based on a hydraulic pressure generated while the engine is stopped; and a rotary electric machine capable of driving the wheels without using the power transmission path. The rotary electric machine is driven when a shift range is the forward range or the reverse range while the internal combustion engine is stopped, and the driving of the rotary electric machine is restrained for a set time after the shift range is changed from the forward range to the reverse range or vice versa while the engine is stopped.Type: ApplicationFiled: February 26, 2013Publication date: October 3, 2013Inventors: Kenta KIMATA, Masahiro ASAI, Kazuhiko MOTODOHI, Shinichiro IGA

Publication number: 20100082208Abstract: An automatic transmission control system calculates a sustention output, needed to sustain a vehicle speed, based on the running resistance, calculates a request output based on, for example, an accelerator pedal angle, calculates a current gear ratio maximum output, which is a maximum output of a vehicle at the current gear ratio, based on the maximum output performance of the engine, and also calculates a post-upshift maximum output that is the maximum output of the vehicle at a gear ratio resulting from an upshift. When a first value based on the sustention output, request output, and a reserve output becomes larger than a second value based on the current gear ratio maximum output, a downshift is decided. When a third value based on the sustention output, request output, and reserve output becomes smaller than a fourth value based on a post-upshift maximum output, upshift is decided.Type: ApplicationFiled: September 16, 2009Publication date: April 1, 2010Applicant: AISIN AW CO., LTD.Inventors: Masahiro ASAI, Keiichirou KUSABE
