  • MAGNETIC ELEMENT AND MANUFACTURING METHOD THEREOF
    Publication number: 20100050420
    Abstract: A manufacturing method of a magnetic element includes the steps of providing a first magnetic material, a second magnetic material, and at least one coil; disposing the coil in a mold; applying the first magnetic material in the coil to form a winding magnetic core; and applying the second magnetic material in the mold to form a magnetic body for covering the winding magnetic core.

  • Protection circuit
    Patent number: 7397643
    Abstract: A protection circuit is coupled between a secondary winding of a transformer and a load. When voltage at the secondary winding of the transformer becomes abnormal, the protection circuit disconnects the power connection to the load so as to protect the load from damage. When the voltage at the secondary winding of the transformer returns normal, the protection circuit restores power to the load.

  • Connector having lighting apparatus
    Publication number: 20070059974
    Abstract: A connector having at least one lighting apparatus is disclosed. The lighting apparatus, such as an LED, includes a lighting portion and two pins. Each of the two pins comprises at least one bent portion. The two pins project from the same surface of the lighting portion. At least one of the pins further comprises an inclined portion for preventing pins contact in the connector.

  • Holographic diffuser
    Patent number: 6285503
    Abstract: Method for the preparation of holographic diffusers where the holographic diffuser is designed through iterative calculations according to the Fraunhofer theory of diffraction and some constrain conditions. In the iterative calculation some constrain conditions that can change the magnitude of the light passing through the diffuser are used to design the diffuser. A novel iterative calculation is disclosed such that uniformed mixing of colors and high light utilization efficiency of the diffuser may be provided.
