  • Patent number: 8112872
    Abstract: A coil component having an easily discernible orientation, and a method of producing such a coil component that facilitates the injection of resin. A coil component includes a core with a winding portion, first and second flanges disposed on either end of the winding portion, and a winding accommodating region defined by the winding portion and the first and second flanges, terminal electrodes disposed on the second flange and a winding wound about the winding portion and connected to the terminal electrodes. An insulating resin is formed over the winding at the winding accommodating region. A marker made from a material the same as the insulating resin is provided at outer peripheral surface of the flanges.

  • Patent number: 7515028
    Abstract: A coil component having a low profile and being conducive to high-density mounting. The coil component includes a core 2 having a coil winding portion, and first and second flanges disposed on either end of the coil winding portion. The second flange is adapted to be mounted on a circuit board, and is configured of a substantially octagonal bottom surface having first and second peripheral surfaces and first through fourth omitted peripheral surfaces. The first terminal electrode is disposed across the first omitted peripheral surface and a part of the bottom surface, and the second terminal electrode is disposed across the second omitted peripheral surface and part of the bottom surface separated from the first terminal electrode. A winding is wound over the coil winding portion and has a first end electrically connected to the first terminal electrode at the first omitted peripheral surface, and a second end electrically connected to the second terminal electrode at the second omitted peripheral surface.

  • Patent number: 4845452
    Abstract: A composite bead element comprises a chip-like magnetic body in a shape of a nearly rectangular parellelepiped in which a recess is provided, at least one feed-through holes formed in said body and an electronic component inserted in said recess. Bead inductors are formed by conductors provided in said feed-through holes, and said electronic component and said conductors are connected by predetermined conductors on a surface of said body.

  • Patent number: 4841267
    Abstract: A deflection apparatus for cathode ray tube is provided, which comprises deflection yoke with guide grooves, deflection windings for scanning in one direction in said grooves, deflection windings for scanning in the other direction and an insulator between both types of windings. It attains high accuracy deflection with less distortion without any induced heating problem due to protuberances made relatively between grooves.

  • Patent number: 4501781
    Abstract: A hollow blow-molded bottle-shaped container of biaxially oriented resin mixture material comprising a polyethylene terephthalate resin and a xylylene group-containing polyamide resin, wherein the resin mixture material contains 5 to 30% of the xylylene group-containing polyamide resin to the polyethylene terephthalate resin. In this container, inner and outer surface layers of the container are formed of the polyethylene terephthalate resin, and the intermediate layer of the container is formed of the mixture resin material. In this manner, the gas barrier properties of the container can be enhanced.
