Abstract: The present invention aims to provide a resin composition capable of providing a molded article that has high slidability and high impact resistance, as well as excellent tensile strength. The present invention relates to a resin composition containing an aromatic polyether ketone resin (I) and a fluororesin (II). The composition preferably has a sodium content of 120 ppm or less relative to the composition or a calcium content of 15 ppm or less relative to the composition.

Abstract: A semiconductor light emitting device includes: a wiring substrate on which a p-electrode and an n-electrode are provided on a substrate; a light-emitting functional layer including a p-type semiconductor layer and an n-type semiconductor layer connected to the p-electrode and the n-electrode, respectively, and bonded onto the wiring substrate; a light-transmitting optical element having a light shielding film provided on a side surface of a plate-shaped light-transmitting optical body and which has an annular frame portion that covers a peripheral edge portion of a back surface of the light-transmitting optical body and formed on the peripheral edge portion; and an adhesive layer configured to adhere the light-transmitting optical element to an upper surface of the wiring substrate such that the light-emitting functional layer is inserted into a recessed portion inside the frame portion. The recessed portion is filled with the adhesive layer.

Abstract: Novel coating compositions for architectural use are provided, which include a quaternary ammonium silicate having a silica content of 10 to 60% by weight and a liquid epoxide resin, besides the conventional ingredients, such as pigments, fillers, aggregates and water, and which are particularly capable of producing films having excellent adherency to mortar or concrete surfaces. If a stabilized silica sol is added to the compositions, films produced therefrom have much improved resistance to water at low temperatures as well as freeze-thaw stability.
