  • Publication number: 20200248783
    Abstract: A vehicle power transmission device includes: an input shaft; an output shaft; a first power transmission path configured to transmit power between the input shaft and the output shaft; and a second power transmission path configured to transmit power between the input shaft and the output shaft. The first power transmission path includes a mode-switching clutch configured to be switched between a one-way mode and a free mode, the one-way mode being a mode in which power acting in a forward rotation direction is transmitted while power acting in a reverse rotation direction is interrupted, and the free mode being a mode in which power acting in the forward rotation direction and power acting in the reverse rotation direction are interrupted. The second power transmission path includes a control clutch configured such that a torque capacity of the control clutch is controllable.

  • Publication number: 20070060807
    Abstract: A pair of light-receiving sections are placed at positions symmetric to a light-emitting axis of a light-emitting section on the inner circumferential surface in close contact with a finger, and each light-receiving section is composed of a plurality of light receiving regions so that by selecting a signal of the light receiving region which maximizes a reception signal, the propriety and the correction direction of a wearing position are displayed. According to the ring sensor, it becomes possible to enhance light-receiving efficiency of the light-receiving section and to increase a signal-noise ratio. It also becomes possible to facilitate wearing of the ring sensor at an optimum position.

  • Patent number: 5078003
    Abstract: An overload protector for press machine protects a press machine from a damage when the press machine receives an overload in operation. It is applicable to a two-point type press machine with two connecting rods between a crank shaft and a slide. A pressurized oil supply means comprising a pressure generator and pressure oil supply line delivers pressurized oil to two hydraulic pressure chambers of two overload-protections means. The pressurized oil supply line has two relief valves connected thereto in hydraulic parallel to each other. Each of the relief valves receives the hydraulic pressure from one of the hydraulic pressure chambers reduced by an occurrence of a localized load and releases the hydraulic pressure contained in the other hydraulic pressure chamber so as to nullify the localized load.

  • Patent number: 4982751
    Abstract: A compact case designed with a technique of enabling a cosmetic material to be discharged always smoothly while maintaining the desired performance of sealing the cosmetic material to prevent the same from hardening. A flat plate is disposed movably in a case body, and a sealed sack to be filled with the cosmetic material is disposed under this flat plate. A pump capable of being driven by the flat plate to discharge the cosmetic material is provided in the sealed sack. The pump has a discharge hole formed in the flat plate. A cover is stretched over the upper surface of the flat plate to cover the discharge hole. A slit is formed in the cover so as to communicate with the discharge hole.
