  • Patent number: 9062757
    Abstract: An automotive transmission is provided that includes a shift lever configured to move in a first direction to select a gear shifting position and a moving member that is configured to move in a second direction along a guide groove formed in the shift lever. A movement blocker is configured to selectively block the movement of the shift lever based on a position of the moving member. The movement blocker includes a rotating member configured to rotate in one direction by the moving member positioned at one side of the guide groove and block the movement of the moving member in the first direction. In addition, a support member to which the rotating member is rotatably connected moves in the second direction by the moving member positioned at the other side of the guide groove.

  • Patent number: 8172633
    Abstract: The present invention relates to a field emission display and a manufacturing method of the same having selective positioning of electron field emitters. More specifically, the present invention provides a field emission display and a manufacturing method of the same having selective positioning of electron field emitters which can prevent a cross-talk that is a mutual interference phenomenon between pixels and improve uniformity of pixels based on uniform electron emission by deciding positions of carbon nano-tubes which are sources of electron emission and growing carbon nano-tubes before the structure of electrodes is formed, and forming spacers directly on electrodes such that the spacers divide carbon nano-tubes formed uniformly and selectively into pixel units.

  • Patent number: 5839292
    Abstract: A defroster for a heat pump to remove frost which falls on an evaporator during a heating operation of the heat pump. The defroster includes a condenser, compressor, and a cylindrical converting valve. A by-pass tube branches off at an outlet of the compressor to induce refrigerant and an on-off valve selectively induces the refrigerant into the bypass tube. A first inlet tube is formed at an upper portion of the cylindrical converting valve for receiving refrigerant drawn by the bypass tube and a first outlet tube emits the refrigerant into an upper portion of the evaporator. A second inlet tube is formed at a lower portion of cylindrical converting valve for receiving refrigerant coming from the condenser and a second outlet tube emits the refrigerant into a lower portion of the evaporator. A converting plate, rotating in the cylindrical converting valve, connects the first inlet tube with the first outlet tube, while connecting the second inlet tube with a second outlet tube.
