  • Patent number: 10345917
    Abstract: An operation device includes a motor capable of forward and reverse rotation, a transmission mechanism configured to convert forward and reverse rotation of the motor into linear ascending and descending motion and to provide tactile stimulation on an operation unit, and a controller configured to control switching of an energizing direction of the motor. The controller is configured to control acceleration such that an amount of ascending movement of the operation unit is increased by increasing driving power in a forward rotation direction of the motor, and to control deceleration such that the ascending movement of the operation unit decelerates by supplying driving power in a reverse rotation direction of the motor, in a predetermined time from when the operation unit starts the ascending movement via the transmission mechanism until a target displacement amount is reached.

  • Patent number: 10014809
    Abstract: A motor driving apparatus includes a driving circuit that drives a motor based on a driving instruction signal at a first state of the first state and a second state which are binarized, a current feedback circuit including a latch circuit, and a controller that outputs the driving instruction signal and a current command signal. The latch circuit latches a third state of the third state and a fourth state which are binarized if a motor current value exceeds a current command value. When the driving instruction signal becomes the second state, the latch circuit releases the latching of the third state and outputs a signal of the fourth state. The controller outputs the driving instruction signal of the second state along with the current command signal so as to release the latching of the latch circuit when outputting the current command signal with the current command value changed.

  • Patent number: 9777757
    Abstract: A fixture includes a base portion and a pair of holding portions on the base portion. Each holding portion include a clamping portion for clamping an object, and a head portion on the clamping portion side opposite to the base portion side. Each head portion includes a through-hole for a fastening member for adjusting a gap between the holding portions. The rigidity of the clamping portions is smaller than the rigidity of the head portions, with respect to deformation caused by the fastening member. The distance from the base portion to end portions of the holding portions in a plane orthogonal to the axial direction of the object is determined according to the tolerance prescribed for the object. The gap when external force is not being applied by the fastening member is determined according to an allowable amount of stress to be applied to the object.

  • Patent number: 9454232
    Abstract: An operating device includes a push operation mechanism including an operating portion to be push-operated, a tactile presenting means that drives the operating portion, a detecting portion for detecting movement of the operating portion, and a drive control unit that drives the driving portion by a drive control signal and a main vibration pulse signal output after outputting the drive control signal, the drive control signal being generated based on a start pulse signal and a pre-vibration pulse signal. The drive control unit sets a mask time to invalidate a detection signal of the detecting portion in a certain period when the drive control signal is output and switches from the output of the drive control signal to the output of the main vibration pulse signal based on a detection signal of the detecting portion after an elapse of the mask time.
