  • Publication number: 20200111882
    Abstract: A semiconductor device includes a semiconductor layer including first and second electrode forming surfaces and side surface, an anode electrode formed on the first electrode forming surface, a cathode electrode formed on the second electrode forming surface; an insulating film continuously formed from the first electrode forming surface to the side surface so as to cover the first edge. The side surface of the semiconductor layer is covered with the insulating film, so that a leak current flowing along the side surface is reduced. Further, the side surface is protected by the insulating film, making cracking, chipping, cleavage, and the like less likely to occur.

  • Publication number: 20200023760
    Abstract: A seat cushion part includes a base fabric extending between and looped around a front edge frame and a rear edge frame, and having an upper layer part and a lower layer part which are provided apart from each other in an up-down direction. Wire members of metal are provided respectively on side edge portions of the base fabric, and coil springs are spring members each extending between an end portion of the wire member and the front edge frame or the rear edge frame. A load further applied due to vibration, impact, and so on causes the upper layer part to come into contact with the lower layer part to also displace the lower layer part in the up-down direction. Consequently, the coil springs connected through the wire members extend/contract, and their elastic force acts.

  • Publication number: 20140038324
    Abstract: In a manufacturing method of a light emitting apparatus, an array of light emitting elements is formed on a substrate. A first lens-pillar-material layer is formed on the array, and first lens pillars are formed on the light emitting elements of the array by performing a photolithographic process on the first lens-pillar-material layer. A lens-portion-material layer is laminated on the first lens pillar using a dry film resist so that gaps are left between the first lens pillars. A plurality of lens portions that correspond to the first lens pillars are formed by performing a heat treatment on the first lens-portion-material layer so that it is softened and enters the gaps. The first lens pillars and the lens portions constitute a lens array that focuses light emitted by the light emitting elements.

  • Patent number: 7829267
    Abstract: A stamper is formed so that a thickness between a concave/convex pattern formation surface, where a concave/convex pattern is formed, and a rear surface gradually decreases in a predetermined area of the stamper. The predetermined area corresponds to an area where pressure is likely to be concentrated when the concave/convex pattern of the stamper is used to form a concave/convex pattern on a substrate. A method of forming a concave/convex pattern uses such stamper, and a method of manufacturing an information recording medium uses a concave/convex pattern formed by such method.
