Abstract: An optical connector ferrule is a member in which an optical fiber is fixed inside a body section, and the distal-end side thereof forms a connection end surface for the optical fiber. An internal space in which the optical fiber is accommodated is formed inside the body section. The internal space runs through from the rear end to the distal end of the body section. An adhesive injection window that is open to the outside is formed in the upper surface of the body section. The adhesive injection window and the internal space are communicated inside the body section via a reduced-diameter section. In plan view, the area (area of the smallest section) of the reduced-diameter section is smaller than the open area of the adhesive injection window.

Abstract: A rubber modified styrene-based resin is provided that is excellent in oil resistance, folding endurance, and tear strength and that is preferably used for a food container and a food container lid member not cracking by repeated fitting. According to the present invention, a rubber modified styrene-based resin is provided that contains rubbery dispersed particles, having a volume median particle diameter from 4.0 to 10 ?m and a gel component from 22.0 to 35.0 mass %; a matrix phase having a weight average molecular weight (Mw) from 150 thousand to 300 thousand; and a methanol soluble component from 1.5% to 4.0%.

Abstract: A process for producing a sintered thermoelectric semiconductor includes a first step of forming bulk crystals of a thermoelectric semiconductor and a second step of hot extrusion. The second step includes substeps of placing the bulk crystals in the cavity of a heated extrusion die, pushing the ram into the cavity, thereby compressing and crushing the bulk crystals and turning them into a molten or semi-molten state, and finally extruding the molten or semi-molten crystals, thereby sintering them and forming a sintered thermoelectric semiconductor.
