  • Patent number: 10041491
    Abstract: In a vane pump, a communication groove that provides communication between a communication hole and a discharge port is formed in an outer side face of a rear housing. An opening of the communication groove is blocked by a fitting face of a control valve case. A back-pressure introduction passage that provides communication between the communication hole and an outlet is formed by the communication groove and the fitting face of the control valve case. The back-pressure introduction passage is formed between the rear housing and the control valve case, that is, on the outer side of the housing.

  • Patent number: 10018689
    Abstract: We describe a method of detecting a voltage from a spin-current, the spin-current comprising a current having a spin predominantly aligned in a spin direction, the method comprising: flowing the spin current through a layer of organic material in a vertical direction through the layer; and detecting an electric field in a lateral direction in the layer of organic material. In a preferred embodiment the organic layer is anisotropic and has a higher electrical conductivity in the lateral direction than in the vertical direction.

  • Publication number: 20130075219
    Abstract: An electromagnetic clutch includes: a first cam member having a first cam surface; a second cam member having a second cam surface facing the first cam surface; a coned disc spring that urges the second cam member such that the first and second cam surfaces are separated from each other; a clutch plate that contacts the second cam member due to urging force of the urging member, and generates friction force between the clutch plate and the second cam member; and an electromagnetic coil that generates magnetic force with which the second cam member is separated from the clutch plate against the urging force of the urging member. The first cam surface and the second cam surface generate thrust force by which the second cam member is pushed against the friction member, through relative rotation between the first cam member and the second cam member due to the friction force.

  • Patent number: 6216815
    Abstract: A power steering apparatus, including a pump, a power cylinder, a control valve and a switching valve. The switching valve is for connecting the cylinder chambers in accordance with pressure change of the operating fluid responsive to operation of the control valve in order to return the steering wheel toward a neutral position. When the rotation of the steering wheel is substantially stopped, the switching valve reacts to the pressure change in order to connect the cylinder chambers, so as that the higher hydraulic pressure of one of the cylinder chamber releases to the other. This hydraulic pressure releasing of the operating fluid returns the power piston toward the neural position, smoothly. The steering wheel also returns toward the neutral position in accordance with the return of the cylinder piston, so as that restoring force of the steering wheel is enhanced.
