  • Plasma display device
    Patent number: 8400443
    Abstract: A plasma display device is provided. The plasma display device can prevent the generation of complementary bright spots or the occurrence of voltage peaking by adjusting the time to apply a bias voltage during a reset period. Thus, it is possible to improve the discharge properties and picture quality of a PDP.
    Type: Grant

  • Bearing support for cylindrical rotating shaft bearing
    Patent number: 5821654
    Abstract: A brushless motor having a plurality of weight reducing holes is disclosed. The weight reducing holes are formed in the thick parts of the stator housing of the motor to prevent shrinkage of the thick parts of the housing when forming the housing through injection molding. The weight reducing holes are formed in the housing by appropriately positioning cores in the mold before injecting melted resin into the mold. The weight reducing holes are formed in a bearing seat mouth of the housing as well as in an outer portion of the mouth.
