  • Patent number: 10678306
    Abstract: A viewing angle changing film capable of changing the viewing angle of a display panel is provided. The viewing angle changing film includes a base film opposed to a display panel, and an attachment having a thickness smaller than a thickness of the base film. The base film can change the viewing angle of the display panel. The attachment is inserted into air gap defined between the display panel and a bezel. The attachment is a separate member from the base film, and is fixed to the base film.

  • Publication number: 20190326054
    Abstract: A method for producing a rare earth magnet includes a molding step of supplying a metal powder including a rare earth element into a mold 2 to form a green compact 10; an orientation step of applying a pulse magnetic field H to the green compact 10 held in the mold 2 to orient the metal powder included in the green compact 10; and a sintering step of sintering the green compact 10 separated from the mold 2 after the orientation step. At least one part of the mold 2 is formed from a resin, and the green compact having a density adjusted to 3.0 g/cm3 or more and 4.4 g/cm3 or less is sintered.

  • Publication number: 20190056764
    Abstract: A connector?substrate assembly can be disposed at a position where a tip portion of the connector is inserted into a connector hole simply and at a low cost without using an additional small substrate, an additional relay cable, and the like; an electronic device; and a method for assembling the same are provided. A connector is supported so as to be slidable with respect to a substrate, from a preparation position to a mounting position, and the tip of the connector projects outwardly from a right side of an end portion of the substrate at least at the mounting position. A chassis has a connector hole in the side surface. The connector does not interfere with a frame portion of the connector hole at the preparation position and the substrate can be properly attached to the chassis. The tip of the connector enters the connector hole at the mounting position.

  • Patent number: 5285354
    Abstract: A controller base unit for a DIN-standard installation wherein a molded base is provided with an internal chassis for support and a contour that permits the direct and releasable attachment of the unit to a DIN rail via a plurality of hooks that are simultaneously moveable between an engaged and non-engaged position. The base is provided with a recess in a planar face thereof for accommodating a printed circuit board and has fixed tabs along the periphery of the recess. The circuit board has cut-outs that mate with the tabs for insertion of the board into the recess and is slidable laterally into a position where the tabs secure the board against the surface of the recess and a screw or the like can secure the board against further lateral movement. The board has at both ends thereof a pair of connectors that are connectable with either end of a separate similarly designed board via a cable.
