  • Publication number: 20200010971
    Abstract: A plating is formed on one side of a cathode by applying a paste composed of particles mixed with a plating liquid to one side of the cathode, disposing a liquid holding member impregnated with the plating liquid on one side of an anode, opposing the cathode and the anode face, and then bringing the liquid holding member and the paste into contact with each other, and applying a voltage between the cathode and the anode.

  • Publication number: 20170263393
    Abstract: A limit switch device is placed at an intended stop position, without the need to move the actuator additionally from the position at which the on/off state is switched. A first movable portion (211) causes a first contact to slide on a second contact in a switch mechanism (103) included in a microswitch by applying a force (F?) via an actuator (102a) and a plunger (102b).

  • Publication number: 20120089858
    Abstract: A content processing apparatus includes a plurality of takers. Each of a plurality of takers runs with reference to any one of N (N: an integer of two or more) of clocks, and the plurality of takers respectively take a plurality of contents. A mixer mixes the plurality of contents respectively taken by the plurality of takers so as to create equal to or less than N of output contents. A changer changes the clock referred to by each of the plurality of takers corresponding to a mode switching. An adjuster adjusts a mixing manner of the mixer in association with a change process of the changer so that a mixing process is executed for every contents corresponding to a common clock.

  • Publication number: 20090039545
    Abstract: The present invention intends to provide a sealing structure of a terminal that is low in a processing temperature for sealing, easy in sealing operation and high in the productivity. In the invention, the thermal expansion coefficient of a sealing material is made equivalent to or more than the linear expansion coefficient of a metallic sealing case block by adding inorganic filler to a liquid thermosetting polymer.

  • Patent number: 7187631
    Abstract: A disc apparatus (10) includes an optical lens (14). A laser beam is irradiated onto a recording surface of the magneto-optical disc (68) through the optical lens (14), and a TE signal or an RF signal is detected on the basis of the laser beam reflected by the recording surface. Herein, an MPU (50) replaces the optical lens (14) in an optical axis direction, and a TE signal detection circuit (42) or an RF signal detection circuit (60) detects the TE signal or the RF signal at each of lens positions. A laser power is adjusted by the MPU (50) such that amplitude of each of the TE signal or the RF signal detected is below a saturation value. When a parameter is adjusted, a position of the optical lens (14) is controlled such that the amplitude of the TE signal or the RF signal detected thereafter is maximized.
