Patent number: 7350499Abstract: A control device for cylinder reducing operation of a multi-cylinder engine for a vehicle controls the number of working cylinders in the engine more appropriately for fuel economy while ensuring the operational stability of the engine and comfortable drivability of the vehicle. The control device comprises a detector detecting engine output torque and judges if cylinder reducing operation is to be executed while referring to the engine output torque. Because of the detection of engine output torque, cylinder reducing operation will be executed as long as torque requested of the engine is available from the reduced number of working cylinders, thereby ensuring the generation of torque required in operating the engine while saving fuel as much as possible. Through a learning process, criteria for the judgment of execution of cylinder reducing operation are modified to be adapted for any variation of engine output performances.Type: GrantFiled: November 5, 2004Date of Patent: April 1, 2008Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshifumi Takaoka, Tadashi Akiyama, Takashi Suzuki, Toshio Inoue

Patent number: 7230598Abstract: An electrical dimmer device and its driving method applicable to, for example, an image pickup unit and a display unit operate so that when a control signal for stop adjustment is changed from its current value of stop adjustment to a larger value, which occurs when the light transmissivity of a positive type liquid crystal is raised, or when the light transmissivity of a negative type liquid crystal is lowered, the control signal is temporarily varied to an intermediate value that is larger than the larger value. The energy of the varied larger value and a time during which that varied value is applied are determined in accordance with predetermined values. By doing so, it is possible to make a response speed when changing the light transmissivity extremely faster and thus attain a response time, of for example, one field period of time or less required for a stop mechanism of a video camera.Type: GrantFiled: April 19, 2002Date of Patent: June 12, 2007Assignee: Sony CorporationInventors: Masaru Kawabata, Toru Udaka, Toshiharu Yanagida, Toshifumi Takaoka, Kazuhiro Tanaka

Patent number: 6867509Abstract: The priority sequence in a control of adjusting the drive power with respect to a vehicle drive power request is set in the sequence of: (1) an engine output increase, (2) a motor output increase, and (3) a gear speed change in a gear ratio increasing direction. More specifically, a gear speed of a least gear ratio is selected within such a range that an engine revolution speed higher than or equal to a predetermined lower limit revolution speed is attainable. A requested drive power is achieved singly by an engine output with the gear speed selected. When the requested drive power is not achievable singly by the engine output, the requested drive power is achieved by the engine output and a motor output. When the requested drive power is not achievable by the engine output and the motor output, the gear speed is changed in a gear ratio increasing direction.Type: GrantFiled: October 23, 2000Date of Patent: March 15, 2005Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshifumi Takaoka, Naoto Suzuki, Takashi Suzuki, Daimon Okada
