  • Optical rotary encoder and manufacturing method thereof
    Patent number: 8704157
    Abstract: A rotating shaft; a boss that has a fitting hole formed in a center portion thereof, has a clean adhering surface at an end thereof, and is configured so that the rotating shaft is fitted into the fitting hole while the boss is fixed to the rotating shaft by a fixing member; a pulse disk that has an interference-fit hole formed in a center portion thereof for the rotating shaft, has a clean adhesion-receiving surface in a surrounding of the interference-fit hole, is configured so that the rotating shaft is pressed into the interference-fit hole and so that the adhesion-receiving surface is adhered to the adhering surface of the boss by an adhesive agent, and has a position detecting pattern formed thereon; a light emitting element that radiates light; and a light receiving element that receives the light from the light emitting element via the position detecting pattern are included.
    Type: Grant

  • Synchronous controller
    Patent number: 6316903
    Abstract: A synchronous controller that can perform high-speed, high-accuracy torque constant control even in applications wherein rapid load variation exists. The torque amount used for a control purpose of pressing a workpiece, etc., can be set as a torque offset correction amount and the torque offset correction amount is added to a torque command generated based on a speed command and speed feedback generated based on a position command and positions feedback.
