  • Patent number: 6325188
    Abstract: A linear motion damping device comprises a cylindrical body having a receiving compartment and an axial hole, in which a dragging rod is slidably disposed such that the threaded portion of the dragging rod is engaged with a fastening member which is confined to turn around the dragging rod at such time when the dragging rod is exerted on by an external force along the axial direction of the dragging rod. The fastening member acts to provide the dragging rod with a damping force at the time when the dragging rod is engaged in a displacement along the axial direction thereof.

  • Patent number: 6229702
    Abstract: A ball grid array semiconductor package includes a substrate, a die mounted on the substrate and electrically connected to the substrate by bonding wires, a heat ring mounted on the substrate to surround the die and the bonding wires, and a heat slug mounted on the heat ring to entirely cover the die and the bonding wires thereby providing improved heat dissipation efficiency and overall electrical performance. Encapsulation material is filled into an inner space surrounded by the heat ring, heat slug and substrate to form an encapsulant for protecting the die and bonding wires. The heat ring and heat slug has at least a portion of surface area sequentially coated with a metal medium layer and an insulation layer to enhance the bonding degree between the encapsulant and the heat ring and heat slug.

  • Patent number: 6029551
    Abstract: A screwdriver is composed of a handle, a magnetic member, a shank, and an adjusting device. The handle is provided with an axial hole in which the magnetic member is disposed. The shank is pivotally disposed in the axial hole such that the shank is fastened at one end thereof with a blade, and that another end of the shank is capable of a mutual attraction with the magnetic member. The magnitude of the mutual attraction is adjusted by the adjusting device to determine a pre-set desired torsional moment. The handle and the shank are capable of turning relative to each other at the time when a torsional moment exerting on the screwdriver is greater than the pre-set desired torsional moment.

  • Patent number: 5421680
    Abstract: A method and a device for preventing a drilling chip from winding around a drill bit and for removing the drilling chip deposited in flutes of the drill bit comprising a drill bit acting as a driving member and a driven gear having at least one tooth engageable with flutes of the drill bit. As the drill bit is turned to drill a hole, the driven gear is actuated to turn such that the tooth of the driven gear engages the flute of the drill bit so as to scrape off any drilling chip deposited in the flute of the drill bit and to prevent the drilling chip from winding around the drill bit in action. The driven gear is rotatably and movably fastened to a support rod which is in turn fastened to a drill press.
