  • Patent number: 10961360
    Abstract: A fiber-reinforced resin material includes a thermoplastic resin and a bundle of reinforced fibers arranged in one direction, the thermoplastic resin being a reactive resin. The thermoplastic resin may be an epoxy resin. The reinforced fibers may be carbon fibers. A molded fiber-reinforced resin body is obtained using the fiber-reinforced resin material. The molded fiber-reinforced resin body may be formed by the application of heat and pressure.
    Type: Grant

  • Patent number: 8421351
    Abstract: The present invention provides a thin organic EL element that can maintain stable emission characteristics for a long time without being affected by water or oxygen. Specifically, the present invention provides an organic EL display panel having a substrate (1), an organic EL element (2) formed on the substrate; and a case (3) encapsulating the organic EL element, wherein a specific hot melt-type member is arranged between the organic EL element and the case.
