  • Patent number: 9856851
    Abstract: An opposed swash plate type fluid pressure rotating machine in which a first piston and a second piston projecting from opposite ends of a cylinder block reciprocate in a cylinder, respectively following a first swash plate and a second swash plate includes a center spring for biasing the cylinder block toward the second swash plate. A housing hole (biasing force receiving part) for receiving a biasing force of the center spring is formed on one end part of the cylinder block. The tip of a second neck (reaction force receiving part) for receiving a reaction force from the second swash plate is formed on the other end part of the cylinder block. The cylinder block is biased only toward the second swash plate by the center spring.

  • Patent number: 9806573
    Abstract: A stator for a rotary electric machine has a tooth whose width in a circumferential direction is substantially constant in a radial direction of the stator, and a concentrated winding coil including winding conducting wires around the tooth. A height of a first conducting wire of the sixth turn at a tooth's top end side measured from a surface of the tooth is lower than a height of a conducting wire adjacent to a tooth's root end side of the conducting wire measured from the tooth surface. Conducting wires of the first to fifth turns, that is, second conducting wires, have the same height from the surface of the tooth.

  • Patent number: 9308938
    Abstract: There is provided a vehicle power steering control apparatus. A steering control unit sets a base assist torque Tb based upon a vehicle speed and a steering torque. When an obstacle ahead is detected by an image recognition device, the steering control unit calculates an overlapping ratio between the obstacle and the vehicle in the widthwise direction. When an absolute value of the overlapping ratio is larger than a predetermined threshold value, the steering control unit increases the base assist torque for correction, and when the absolute value is equal to or smaller than the predetermined threshold value, it decreases the base assist torque for correction. The steering control unit outputs the calculated value to a motor drive unit as a control quantity (assist torque).
