Patent number: 7307407Abstract: In a power supply apparatus, in a standby mode, control signals for controlling a first MOSFET of a power supply apparatus to be turned on and a second MOSFET to be turned off are supplied to the gates of the first and second MOSFETs from a control circuit, respectively. The emitter of a PNP transistor is connected to the gate of the second MOSFET through a diode of a switch circuit and the collector is connected to the ground. A power supply operation control signal is input to the base of the PNP transistor. When a power supply operation control signal in a Low state is input to the base in a standby mode, the emitter and the collector are connected to each other. Accordingly, the gate of the second MOSFET has a potential substantially the same as a ground potential and the second MOSFET is turned off irrespective of the control signal.Type: GrantFiled: January 19, 2007Date of Patent: December 11, 2007Assignee: Murata Manufacturing Co., Ltd.Inventors: Koji Nishi, Soichi Watanabe, Takashi Kurokawa

Publication number: 20060108026Abstract: A power transmission shaft which can be evaluated on torsional fatigue strength based on a management indicator different from compressive residual stress in an outer surface. In a power transmission shaft having outer circumferential serrations 1a, 1b, torsional fatigue strength is evaluated by using compressive residual stress at a depth of 30 ?m (and 50 ?m) from an outer surface of a rising portion of each concave of the outer circumferential serrations 1a, 1b as a management indicator. A high torsional fatigue strength can be secured by having a compressive residual stress of 1150 MPa or more at a depth of 30 ?m (and 50 ?m) from the outer surface.Type: ApplicationFiled: November 18, 2005Publication date: May 25, 2006Applicant: TOYODA KOKI KABUSHIKI KAISHAInventors: Kazuyuki Ichikawa, Isashi Kashiwagi, Miwa Hokii, Koji Nishi, Toshiyuki Saito
