  • Patent number: 11215970
    Abstract: A processing control device controls a tool for processing a first workpiece. The processing control device includes a driving unit to drive the tool, an output unit, and a control unit to control the driving unit and the output unit. Processing information obtained by performing preliminary processing on a second workpiece before performing first processing on the first workpiece is transmitted by the control unit to the output unit and accordingly the processing information is outputted from the output unit. The control unit generates a control command for performing second processing that is performed on the first workpiece after the first processing. The control unit controls the driving unit according to the control command.

  • Patent number: 9334845
    Abstract: The engine starting device includes a pinion unit which is spline-coupled to an output shaft side of a starter motor to slide in an axial direction, the pinion unit including a one-way clutch which spins for rotation in the same direction as that of rotation of the engine, and a pushing mechanism for moving the pinion unit to a position in which the pinion unit comes into meshing engagement with a ring gear. A pinion gear of the pinion unit is movable in the axial direction as a single body, and includes a chamfered portion having a curved surface along a tooth surface on a non-torque transmitting surface side and a large length in the axial direction, the chamfered portion being provided to a ring-gear side distal end portion of the tooth surface on the non-torque transmitting surface side.
