  • Patent number: 5944544
    Abstract: A rotary connector including a fixed housing 1 equipped with an outer cylindrical wall 6, a movable housing 2 provided with an inner cylindrical wall 7, and two flat cables 3, 4 housed in a storage section 8 defined between the fixed housing 1 and the movable housing 2 and wound in a manner of inverting their winding direction halfway. Both end portions of each of the flat cables 3, 4 are fixed to the circumferential surfaces of the outer cylindrical wall 6 and the inner cylindrical wall 7. Cable fetching sections 7a, 7b for taking out the flat cables 3, 4 from the inner cylindrical wall 7 are disposed in substantially 180-degree opposed relation to each other, and a movable side joint section 12 is provided in the movable housing 2 to gather up the separated flat cables 3, 4 in one place. One end portions of the flat cables 3, 4 are led out through the movable side joint section 12 to the exterior of the movable housing 2.
    Type: Grant

  • Patent number: 4750084
    Abstract: A ceramic laminated capacitor having an approximately cylindrical external configuration. Dielectric layers and inner electrode layers are laminated, and the inner electrode layers are connected to outer electrodes to unite them into one body. A pair of insulators having a vertical section of a segment are bonded to the opposing end surfaces of the dielectric layers such that the convex surfaces of the insulators face outward.

  • Patent number: 4529960
    Abstract: A chip resistor provided with a thin-film resistor has lateral electrodes formed at both sides of the substrate of the chip resistor. The lateral electrodes are formed by printing and firing conductive paste of a silver resin, not by thin-film technology. Electrode layers are formed on the lateral electrodes and on the thin-film electrode by plating. The chip resistor is thus constructed so as to be readily connectable to a motherboard by dip soldering or reflow soldering.
