Patent number: 6681620Abstract: A method and apparatus for conducting a vehicle performance evaluation test by automatically depressing a control member of the vehicle to be depressed by a vehicle operator uses an actuator of a vehicle performance evaluation test apparatus. The actuator depresses the control member, the actuator having a first end and a second end. The first end of the actuator is fixed to a seat of the vehicle. The second end of the actuator is engaged with the control member of the vehicle. The actuator is caused to exert a depressing force to depress the control member relative to the seat so as to automatically depress the control member.Type: GrantFiled: March 11, 2002Date of Patent: January 27, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shigeru Sakamoto, Junichi Takeda, Norihiko Okochi, Tetsuya Ogawa, Osamu Takenaka

Patent number: 5221125Abstract: A fluid leakage preventing device incorporated in a hydraulically-operated system which includes an accumulator for storing a working fluid under pressure, an actuator operated by the fluid supplied from the accumulator, and a control valve having an open position and a closed position for fluid communication and disconnection between the accumulator and the actuator, respectively. The fluid leakage preventing device includes a fluid leakage detector for generating an output signal indicative of the leakage flow of the fluid from said accumulator through the control valve placed in the closed position. The device further includes a valve reciprocating arrangement responsive to the output signal of said fluid leakage detector, for effecting at least one reciprocating movement of a valving member of the control valve.Type: GrantFiled: June 6, 1991Date of Patent: June 22, 1993Assignee: Toyota Jidosha Kabushiki KaishaInventors: Norihiko Okochi, Yoshihisa Nomura, Susumu Masutomi
