Patent number: 7399171Abstract: The curvature of a circular arc constituted by a side of a suction groove is made larger than that of a circular arc constituted by a side of a discharge groove. Thus, when the suction groove and the discharge groove are viewed in the axial direction of a drive shaft, the distance between the suction groove and the discharge groove in the radial direction of a rotary portion is short in a region intersecting with a line W perpendicular to a centerline, and increases in accordance with a decrease in distance from containment portions. It is therefore possible to ensure a sufficient distance between the discharge and suction grooves and enhance a total fluid pressure generated therebetween, and the contact surface pressure that is necessitated by a second side plate to obtain a press-back force when being in contact with an outer rotor and an inner rotor is reduced.Type: GrantFiled: October 27, 2005Date of Patent: July 15, 2008Assignees: Advics Co., Ltd., DENSO CORPORATION, Nippon Soken, Inc.Inventors: Takahiro Yamaguchi, Takashi Satou, Shigeki Torii, Toshiya Hayashi, Akihiro Yada, Hitoshi Mizutani, Takuya Fukitsuke, Kazunori Uchiyama, Naoki Hakamada

Patent number: 7123049Abstract: In this invention, a control circuit (111) controls both the power supply voltage (VDDQ) and the transistor size of the external output buffer to thereby select the lowest supply voltage that achieves the impedance matching with the transmission line (100), to thereby save bus termination by a resistor, thus consequently achieving both the lowering of the power consumption and the speeding-up in the data transmission. The power consumption during the data transmission is proportional to the square of the supply voltage. If the operational supply voltage of the external output buffer is lowered, the power consumption will be reduced accordingly. If the operational supply voltage of the external output buffer is lowered, the impedance thereof will be increased apparently; and at the same time, if the transistor size of the external output buffer is increased, the increased impedance will be decreased.Type: GrantFiled: July 26, 2005Date of Patent: October 17, 2006Assignee: Renesas Technology CorporationInventors: Takashi Satou, Shigezumi Matsui, Peter Lee, Gouichi Yokomizo
