Patent number: 8716427Abstract: A two-component curable solventless adhesive which enables a laminated composite film comprising a barrier layer and a plastic film laminated with each other to maintain excellent appearance and adhesive strength for a long period even after a sterilization treatment at high temperature, and to appropriately adjust a reaction between a base resin and a curing agent during a production of the laminated composite film. The two-component curable solventless adhesive comprises a base resin and a curing agent, wherein the base resin contains a polyol having an acid group and a secondary or tertiary terminal hydroxyl group accounting for 30% or more of the entire terminal hydroxyl groups of the polyol, and the curing agent contains an isocyanate group-terminated urethane prepolymer containing at least an aralkyl polyisocyanate and/or a modified substance thereof as a raw polyisocyanate, and a content of a low molecular weight polyisocyanate is defined.Type: GrantFiled: February 4, 2005Date of Patent: May 6, 2014Assignee: Mitsui Chemicals, Inc.Inventors: Akihiro Imai, Kazuaki Imamura, Taiji Morimoto, Hiroshi Kawasaki, Mikio Matsufuji

Patent number: 8604506Abstract: This invention provides a surface mounting type light emitting diode excellent in heat radiation performance, reliability and productivity. The surface mounting type light emitting diode includes a metallic base member, a semiconductor light emitting element having a bottom face fixedly bonded to a top face of the base member, and a metallic reflector joined to the top face of the base member with a heat conduction type adhesive sheet interposed therebetween, to surround the semiconductor light emitting element. Heat generated from the semiconductor light emitting element is transferred to the reflector via the base member and the heat conduction type adhesive sheet, and then is radiated to the outside. The metallic reflector can efficiently radiate the heat to the outside. The cutting margin provided for the reflector facilitates a dicing process, which improves productivity.Type: GrantFiled: February 21, 2008Date of Patent: December 10, 2013Assignee: Sharp Kabushiki KaishaInventors: Masahiro Konishi, Toshio Hata, Taiji Morimoto

Patent number: 8358388Abstract: Light-emitting elements are divided into chromaticity groups on the basis of their chromaticity. In a planar light source, light-emitting elements selected from two of the chromaticity groups are alternately provided in a longitudinal direction and in a transverse direction, respectively. The two chromaticity groups are substantially equally away from a target chromaticity in directions reverse to each other. Further, pairs of two of the light-emitting elements belonging to the two chromaticity groups which are separated from each other, are provided so that distances d2 at which two of the light-emitting elements in each of the pairs are provided are less than distances d1 at which the pairs are provided.Type: GrantFiled: May 5, 2011Date of Patent: January 22, 2013Assignee: Sharp Kabushiki KaishaInventors: Osamu Kawasaki, Taiji Morimoto, Masanori Watanabe

Patent number: 7700964Abstract: In a light emitting apparatus using LEDs, luminance and chromaticity of the LED changes largely due to a temperature change. Meanwhile, by using phosphors, it is possible to improve the stability of the luminance and chromaticity against the temperature change. However, color reproducibility of the light emitting apparatus decreases. Therefore, the light emitting apparatus includes a first LED, a second LED, a first phosphor which is excited by the second LED and emits light whose color is the same as or similar to a color of light emitted from the first LED, and a control circuit which controls a ratio between an emission intensity of the first LED and an emission intensity of the second LED.Type: GrantFiled: May 29, 2007Date of Patent: April 20, 2010Assignee: Sharp Kabushiki KaishaInventors: Taiji Morimoto, Masanori Watanabe
