  • Patent number: 9095890
    Abstract: A metallic glass fastening screw that is not susceptible to loosening, and is capable of implementing fastening with high strength and reliability. In processing a screw thread and a screw groove of a screw, amorphous bulk metallic glass is form-rolled at glass transition temperature or less of the bulk metallic glass serving as a member to be processed. The bulk metallic glass has a plastic strain property introduced by plastic working such as form rolling, to improve ductility. A relationship of d>0.022×D is set so that a depth from a bottom of the screw groove in the region where the plastic strain is introduced is d and an outside diameter of the screw is D, to relax stress concentration of tensile stress generated in a region at the bottom of the screw groove due to tension (axial force) applied to the screw in fastening.

  • Patent number: 8330700
    Abstract: In an active matrix display device, one source line is arranged for every two pixels arranged along a gate line direction, and each two pixels which are adjacent to each other along the gate line direction across one of the source lines share the source line and are each connected to different gate lines. A gate driver block performs a first driving control which sequentially selects, in a first order, the gate lines in a pair of two gate lines corresponding to two pixels which are adjacent to each other along the gate line direction and are connected to different source lines. The gate driver block also performs a second driving control which sequentially selects, in a second order which is opposite to the first order, the gate lines in such a pair of two gate lines.

  • Publication number: 20080031557
    Abstract: A rolling guide device 160 is provided with a track rail 161 as a track member and a movable member 163 mounted to the track rail 161 to be movable through balls 162. A solid lubricant film is formed to the ball 162 by using a closed magnetic field unbalanced magnetron spattering apparatus (CUMS apparatus). The solid lubricant film has a low friction coefficient at the outermost surface of the film, withstands an inner repeated stress, and has a high adhesion performance. Such solid lubricant film has never been from its inside or boundary portion and wears at the minimum speed from the film surface, so that a reliable and highly ideal solid lubricating function can be attained, and by applying the solid lubricant film having improved adhesion performance and abrasion resistance to the rolling guide device, there can be provided a rolling guide device usable in a specific environmental condition such as an undesirable lubricating environment, high temperature vacuum condition, or an oil-free condition.

  • Publication number: 20040150702
    Abstract: A decoloring ink for ink jet printing containing an Monascus pigment. An inclusion of an Monascus pigment enables printed characters and/or images to be preserved as long as they are kept in the dark, but they are quickly decolored on exposure to visible light and/or ultraviolet light when they are no longer needed.
