  • Patent number: 11952647
    Abstract: There is provided a ferritic lightweight steel which contains 2.0 to 3.0 wt % manganese (Mn), 5.0 to 6.0 wt % aluminum (Al) and 0.1 to 0.3 wt % carbon (C) and has a tensile strength of 900 MPa to 1,108 MPa. The lightweight steel includes ferrite-austenite dual grains as a result of performing low-temperature tempering-induced partitioning (LTP) at 300° C. for 10 minutes after isothermal annealing.

  • Patent number: 8896794
    Abstract: A liquid crystal display device and a fabrication method thereof, are discussed. According to an embodiment, the liquid crystal display device includes gate lines on a substrate; data lines on the substrate; common lines disposed substantially in parallel to the gate lines; TFTs formed at intersections between the gate and data lines, each of the TFTs including a gate electrode extending from the corresponding gate line, a gate insulation layer, an active layer, an ohmic contact layer, a source electrode extending from the corresponding data line and a drain electrode spaced apart from the source electrode; passivation layers, each formed on the TFT and having a contact hole for exposing a part of the corresponding drain electrode; and pixel electrodes, each composed of a conductive layer and an insulation layer formed on the corresponding passivation layer and electrically connected to the corresponding drain electrode via the corresponding contact hole.

  • Patent number: 7938353
    Abstract: Disclosed herein is a brake system for a fishing reel. The brake system includes a spool cover which is provided between a spool and a left cover, and a brake assembly which is provided between the spool and the spool cover. The spool cover has a cylindrical inner sidewall, a first brake collar which is provided on the inner surface of the sidewall, a circular protrusion which is provided on the central portion of the spool cover, and a second brake collar or one way ring which is provided on the circular protrusion. The brake assembly includes a brake housing, brake shoes, expansion springs, and a housing cover. The brake housing has inner seating depressions and outer seating depressions therein. The brake shoes are inserted into the inner seating depressions. The expansion springs are inserted into the inner seating depressions to elastically support the brake shoes.
