  • Patent number: 9683617
    Abstract: A self-locking mechanism has a driving member, a driven member, a stationary member, a lock holder and a number of lock elements. The lock holder encircles the driving member and the driven member. The lock holder has a support base and ribs extending from the support base. A lock element is coupled to the axial end portion of each rib. The lock elements are radially positioned between a radially outer surface of the driven member and the inner wall of the stationary member. The distance between the radially outer surface and the inner wall gradually decreases from a center to opposite circumferential sides. The maximum distance between the radially outer surface and the inner wall is greater than the diameter of the lock element, and the minimum distance is less than the diameter of the lock element.

  • Publication number: 20160223040
    Abstract: An actuator for an electric parking brake system includes a motor, an output member, and a speed reduction device. The speed reduction device includes a transmission mechanism and a self-locking mechanism. The self-locking mechanism includes a fixed member, first and second rotating bodies, and a spring. The second rotating body transmits torque to the output member via a planetary gear mechanism. The spring prevents the brake from driving the motor.

  • Publication number: 20160201745
    Abstract: An actuator of an electric parking brake system includes a motor, an output member, and a transmission device. The transmission device includes a housing, a self-locking unit and a transmission unit. The self-locking unit includes a fixed sleeve, and a driving member, a driven member and a lock holder that are rotatable with respect to the sleeve. The lock holder supports lock elements arranged to prevent the driven member from turning unless it is driven by the driving member. A planetary gear unit may be provided as part of the transmission device.

  • Publication number: 20160190757
    Abstract: A brush for an electric motor has a brush body having a front end surface configured to make sliding electrical contact with a commutator of the motor. First and second side surfaces are connected to the front end surface. The first side surface and the second side surface are positioned on opposite sides of the brush body in a rotational direction of the commutator. The front end surface has a first contact surface and a second contact surface that contact the commutator earlier than other regions of the front end surface, and are respectively positioned on diametrically opposed corners of the front end surface. In an initial state, the width of the contact area between the brush and the commutator is increased to extend the commutation time.

  • Publication number: 20150335661
    Abstract: The present invention refers to a medicament which activates gastrointestinal movement. The medicament consists essentially of Cucurbitacin D and one or more substances form the group including Cucurbitacin A, Cucurbitacin B, Cucurbitacin E, Isocucurbitacin B and Isocucurbitacin D. The medicament is made from an extract obtained from Muskmelon Base, the fruit stem of Cucumis melo L. The medicament can promote enterokinesia in both normal animals and in animal models where gastrointestinal movement is inhibited. It has also been demonstrated to activate the movements of the stomach, small and large intestines. The extract may be used alone or in combination with the other botanical ingredients or chemical substances to form the pharmaceutical preparation.

  • Patent number: 8202565
    Abstract: A flux spraying system controls a flux sprayer to selectively spray soldering flux onto a printed circuit board (PCB) by a fixture. The fixture is disposed between the PCB and the flux sprayer, and comprises a plurality of openings corresponding to target areas of the PCB. The flux spraying system comprises a statistic module, a calculation module, and a control module. The statistic module records attributes of the fixture to determine spraying areas on the fixture. The calculation module calculates movement parameters of the flux sprayer, a movement length during a movement period and spraying segments of the flux sprayer, and spray duration of the flux sprayer based on the movement length during one movement period and the spraying segments of the flux sprayer. The control module directs the flux sprayer to coat the target areas of the PCB through the openings of the fixture.
