  • Patent number: 7898612
    Abstract: A liquid crystal display panel is placed on an upper mold, and a liquid crystal shutter is stored in a lower mold. Fluorescent lamps serving as a light source are disposed along the internal surface of the lower mold. A display object is disposed on the back of the lower mold. Display images can be changed by switching signals to be applied to the liquid crystal shutter or liquid crystal display panel. The cables for the fluorescent lamps are laid in a groove-like concave section formed in the upper part of the lower mold. A flexible cable extended from the liquid crystal shutter is bonded to a notched portion of the upper part of the lower mold, and coupled to a printed circuit board disposed on the flank of the lower mold.

  • Patent number: 7146597
    Abstract: A design method encompasses: determining a direction of a subject wiring level in a multi-level interconnection of semiconductor integrated circuit as a subject-level priority direction; designing a layout of the subject wiring level, by placing a subject-level strip extending along the subject-level priority; generating a subject-level extension extending in a different direction of the subject-level priority direction, from a termination of the subject-level strip; allocating via-holes in the subject-level extension; and designing a layout of a neighboring wiring level of the subject wiring level, by placing a neighboring-level strip extending along the same direction as the subject-level extension extends, so that a termination of the neighboring-level strip can include the via-holes.

  • Patent number: 6073327
    Abstract: A reusable plug device for providing sealing of an opening of a rim of a wheel for leak testing has a simple structure and facilitates installation/removal of the plug device using a simple insertion tool and a removal tool. The plug body has an axially extending cavity for receiving the insertion tool to enable the plug body to be inserted until a flange section of the plug body abuts the surface of the workpiece. The flange section serves as a stopper to indicate the stop position and ensures a uniform installation of the plug device in each workpiece. For removal of the plug body, the removal tool is inserted into the cavity and the removal tool is pushed in the insertion direction, so that the plug body and the flange section both collapse inward into the cavity to enable the plug device to be simply pushed out through the opening section.
