  • Publication number: 20180133870
    Abstract: A screwdriver tool contains: an operation rod and a magnetic attraction assembly. The operation rod includes a tool segment, a neck section, a first stop face, and a second stop face. The magnetic attraction assembly includes a slidable sleeve having an accommodation section, a magnetic attracting loop, an extension piece, and a covering piece. A diameter of the neck section is less than that of the tool segment, and an inner diameter of the accommodation section is more than an outer diameter of the tool segment. The extension piece and the covering piece of the slidable sleeve have at least one flange extending to the neck section and limited between the first stop face and the second stop face, hence the at least one flange of the extension piece and the covering piece slides on the neck section between the first stop face and the second stop face.

  • Patent number: 9916796
    Abstract: The present examples relate to a liquid crystal display device with a repair function. The present examples repair a defect of a line or a defect of a pixel, using a specialized data signal structure, wherein the data signal structure integrates channel data, which is required for channel driving of a liquid crystal display element, and repair amplifier data, which is used for repairing a defect of a line and/or a pixel. Thus, examples have a better repair function than an alternative liquid crystal display device.

  • Patent number: 9905185
    Abstract: A column driver of a display device provides a high slew rate with lowered power requirements by using external switches connected to upper and bottom output buffers. The upper output buffer is driven between a first voltage rail and a second voltage rail, and outputs a first output signal in response to a first input signal and a second input signal. The bottom output buffer is driven between the second voltage rail and a third voltage rail, and outputs a second output signal in response to a third input signal and a fourth input signal. A first switch group selectively provides input for the upper output buffer and the bottom output buffer. A second switch group feeds back the first and the second output signals to the first or the second input terminal of each of the upper output buffer and the bottom output buffer.

  • Patent number: 9506686
    Abstract: Disclosed herein is a refrigerator in which a level difference between an inner cabinet and an outer cabinet is improved in coupling the inner cabinet with the outer cabinet by forming a corner of the inner cabinet located at a portion coupled with the outer cabinet to have a smaller radius. The refrigerator includes an inner cabinet in which a storage chamber is formed. The refrigerator also includes an outer cabinet coupled with an outside of the inner cabinet and configured to form an exterior. The refrigerator further includes an insulating material filling between the inner cabinet and the outer cabinet. The inner cabinet includes a storage portion configured to form the storage chamber. The inner cabinet also includes an edge portion configured to extend in a vertical direction toward the outside of the storage portion from a front surface edge of the storage portion and exposed to the outside.
