  • Patent number: 10814499
    Abstract: A piston accommodated in an internal space of a cylinder and forming a pair of pressure chambers together with the cylinder, the piston being configured to move relative to the cylinder; a first actuator connected to one pair of pressure chambers; a second actuator connected to the other of the pair of pressure chambers; a position detector configured to detect a position of the piston relative to the cylinder; a pressure detector configured to detect a pressure of one pair of pressure chambers; and a controller configured to control the first actuator and the second actuator. The controller controls one of the first actuator and the second actuator that the position detected by the position detector is made close to a target position and controls the other of the first actuator and the second actuator that the pressure detected by the pressure detector is made close to a target pressure.

  • Publication number: 20200248719
    Abstract: A hydraulic drive apparatus includes: an electric motor; a variable displacement pump driven by the electric motor, the pump including a pair of pump ports whose delivery side and suction side are switched with each other in accordance with a rotation direction of the electric motor; a hydraulic actuator connected to the pair of pump ports by a first supply/discharge line and a second supply/discharge line; and a control device that controls the electric motor based on an actuator position command value for the hydraulic actuator. The pump is configured such that a volume of the pump decreases in accordance with increase in a pressure difference between the first supply/discharge line and the second supply/discharge line.

  • Publication number: 20200129943
    Abstract: Provided is an explosive body X, i.e., an explosive body for nanodiamond synthesis, includes at least an explosive main body (10) that includes a frustum part (11) and a columnar part (12). The frustum part (11) includes an upper bottom surface (11a) including an open end of a hole (H), in which a triggering unit is received, and an angled side surface (11b) forming an imaginary apex angle ? on the upper bottom surface (11a) side. The columnar part (12) is formed contiguous with the frustum part (11) on an opposite side of the frustum part (11) to the upper bottom surface (11a) of the frustum part (11) and extends in a direction away from the upper bottom surface (11a). The explosive body for nanodiamond synthesis is suitable for improving the yield in nanodiamond synthesis by a detonation method.

  • Patent number: 9821782
    Abstract: A motor pump includes a base body, a pump, and a motor. The motor includes a tubular yoke having a bottom and an opening on a base body side, a bearing, a rotation shaft, a rotor, a commutator, a brush and a brush shaft. The bearing is fitted to an inside of a bearing hole of the base body. The brush holder is fitted to an inside of the yoke and engages with an outer peripheral surface of the bearing. The brush holder and the bearing are disposed so as to be spaced from the base body in an axial direction of the rotation shaft. The motor-side seal member is provided between the yoke and the base body. The base body constitutes a stopper that prevents the brush holder from being extracted from the yoke.
