  • Publication number: 20190145434
    Abstract: A hydraulic actuator includes a switching part that is provided with an oil passage for sending pressurized oil generated by a hydraulic pump to a tool and returning return oil from the tool to the hydraulic pump. The switching part switches a route of at least one of the pressurized oil and the return oil. The switching part includes an operating portion (for example, an operation knob) and an axis portion (for example, a spool) that advances or retreats when the operating portion is turned. When the operating portion is turned, the axis portion advances or retreats in a direction orthogonal to a direction of turning the operating portion, whereby the route of the oil passage is switched.

  • Patent number: 10144282
    Abstract: A shift position switching device for shifting gears in association with a shift position. The device includes a shift mechanism switching between shift positions using a drive power of a motor, an encoder outputting pulse signals in sync with a rotation of the motor, and a controller rotating the motor to a target rotation position corresponding to an intended gear. The controller rotates the motor toward a dead-end on a first shift position side of the shift mechanism while observing a motor rotation speed or an acceleration of rotation of the motor based on the outputted pulse signals of the encoder. Also, the controller learns, as a reference position on the first shift position side, a first rotation position of the motor.

  • Patent number: 9584053
    Abstract: A SBW-ECU prohibits driving of an electric motor by turning off power supply to the motor by a drive prohibition device, when a diagnosis part of a by-wire control circuit determines that a shift-by-wire system is abnormal or a monitor circuit determines that the by-wire control circuit is abnormal. In this case, the motor is stopped from rotating by execution of power supply phase fixation processing, by which a power supply phase of the motor is fixed without switchover, when the motor is driven to rotate at the time of determination of abnormality of the shift-by-wire system. Then the prohibition device prohibits driving of the motor by stopping the power supply to the motor.
