Abstract: The white light emitting diode comprising a light emitting component using a semiconductor as a light emitting layer and a phosphor which absorbs a part of light emitted by the light emitting component and emits light of wavelength different from that of the absorbed light, wherein the light emitting layer of the light emitting component is a nitride compound semiconductor and the phosphor contains garnet fluorescent material activated with cerium which contains at least one element selected from the group consisting of Y, Lu, Sc, La, Gd and Sm, and at least one element selected from the group consisting of Al, Ga and In and, and is subject to less deterioration of emission characteristic even when used with high luminance for a long period of time.

Abstract: A moisture-curable, hot melt composition comprising a graft polyurethane prepolymer made by reacting a macromonomer, polyol, polyisocyanate and optional silane reagent is provided. The composition advantageously provides adhesives having initial creep resistance, short set times, and long open times.

Abstract: There are provided moisture-curable hot-melt compositions comprising a polyurethane prepolymer and a crystalline polymer obtained from monomer(s) containing at least one crystalline ethylenically unsaturated monomer with no active hydrogen, which have low melt viscosities and high initial impact strength and final strength. The monomers may also contain amorphous ethylenically unsaturated monomers with no active hydrogen, in addition to the crystalline monomer. Typical crystalline monomers are (meth)acrylate esters of non-tertiary alcohols, the alkyl portions of which comprise 16 or more carbon atoms. Typical amorphous monomers are (meth)acrylate esters of non-tertiary alcohols, the alkyl portions of which comprise no more than 15 carbon atoms. Use of an alkyl acrylamide as one of the amorphous monomers is advantageous for improving the performance of the moisture-curable hot-melt adhesive.

Abstract: A method and apparatus for reproducing data compressed in accordance with a motion picture experts group (MPEG) standard and recorded on a recording medium. The data represents a plurality of frames which correspond to a plurality of groups of pictures (GOPs), in which each of the GOPs includes different types of pictures including intraframe predictively (I) encoded and interframe predictively (P) encoded pictures. The compressed data is read from the recording medium, and the type of pictures corresponding to the read data is determined. The read image data is decoded and supplied to a display device. When special processing (such as, random accessing) is performed, image data may not be properly decoded during an initial period. During this time period, an auxiliary signal may be supplied to the display device.
