  • Patent number: 11638349
    Abstract: A metal-clad laminate includes: an insulating layer; and a metal layer stacked on the insulating layer. The insulating layer includes: a first layer; and a second layer interposed between the first layer and the metal layer. The first layer contains a cured product of a first resin composition containing composite particles. The second layer contains a cured product of a second resin composition. The first resin composition contains composite particles, each having a core containing a fluororesin and a shell containing a silicon oxide that coats the core at least partially. The second resin composition may or may not contain composite particles. When the second resin composition contains the composite particles, a ratio of the composite particles in the second resin composition to solid content of the second resin composition is lower than a ratio of the composite particles in the first resin composition to solid content of the first resin composition.

  • Patent number: 11452216
    Abstract: A first stack is formed by stacking a first sheet of metal foil, a first prepreg, and a second sheet of metal foil, one on top of another. The first prepreg is thermally cured by thermally pressing these members to make a double-sided metal-clad laminate. Conductor wiring is formed by partially removing the first sheet of metal foil from the double-sided metal-clad laminate to make a printed wiring board. After a third sheet of metal foil has been preheated, the conductor wiring of the printed wiring board, a second prepreg, and the third sheet of metal foil are stacked one on top of another and thermally pressed together. The first insulating layer has a lower linear expansion coefficient than any of the first sheet of metal foil or the second sheet of metal foil does.

  • Patent number: 10825963
    Abstract: Provided is a light-emitting device and a method for manufacturing the same which avoid a distinct color unevenness during the light emission even if variations are present among the light-emitting elements in the concentration of the phosphor that precipitates in the resin for sealing the light-emitting elements. The light-emitting device includes a substrate, a plurality of light-emitting elements that are mounted on the substrate, a first resin layer that integrally seals the light-emitting elements and includes a first phosphor that is excited by light from the light-emitting elements at a concentration that is high as it goes to a lower end near the substrate from an upper end distant from the substrate, and a second resin layer that is provided at an upper side of the first resin layer and includes a second phosphor that is excited by light from the light-emitting elements at a uniform concentration.

  • Patent number: 10181553
    Abstract: A semiconductor device directly joins electrodes of a semiconductor element to electrodes of a metal substrate and has good yield, connection reliability, good mass productivity, and superior heat dissipation efficiency. A method for producing the semiconductor device that directly joins the electrodes of the metal substrate to the electrodes of the semiconductor element includes forming an electrode separating groove in an element mounting position on a main surface of the metal substrate at a predetermined depth. The semiconductor element is mounted to extend over the electrode separating groove. The metal substrate is ground from a surface reverse to the main surface of the metal substrate up to a position reaching the electrode separating groove.

  • Publication number: 20180211477
    Abstract: When a stopped symbol group satisfies a winning combination establishment condition, a video slot machine sets a stopping order of at least one reel having stopped symbols including a symbol required for the winning combination to be the last. When the stopped symbol group is one short of the symbol to satisfy the winning combination establishment condition, the stopping order of a reel involving the missing symbol is set to be the last. Display control is performed in such a manner that the reels that are spinning displayed stop spinning in accordance with the stopping orders thus set.

  • Publication number: 20180040780
    Abstract: A light-emitting device includes a metal substrate, insulative portions, a plurality of LEDs, a support frame, and a light-transmissive encapsulation resin. The metal substrate includes electrode portions. The insulative portions separate the electrode portions from each other so that one serves as an anode and another serves as a cathode. The LEDs are positioned at a surface of the metal substrate. The LEDs each lie over a corresponding one of the insulative portions and are each electrically coupled to corresponding ones of the electrode portions. The support frame surrounds an outer perimeter of the metal substrate, and includes inner and outer wall portions. The inner wall portion is formed within a recessed groove along the outer perimeter of the metal substrate. The outer wall portion covers an outer perimeter surface of the metal substrate. The light-transmissive encapsulation resin encapsulates at least partially the LEDs.
