Abstract: A powdered wheat protein that can achieve both a high dough-formation speed and a high bulk density is obtained by drying a pasty raw material formed by kneading a wheat protein, an acid, and water, by flash drying or freeze drying.

Abstract: A connector (50) includes a tubular member (52) and a base tube (58). A light-guiding tube (60) is drawn out from the base tube (58) toward the opposite side to the tubular member (52). An adapter (1) includes: a first connecting portion (10) that can be connected to and disconnected from a light source device (70); a second connecting portion (20) that can be connected to and disconnected from the connector (50); and a light-guiding member (30) that guides light emitted from the light source device (70) to a proximal end surface (61) of the tube (60).

Abstract: A heat receiving jacket in a liquid cooling device for electronic equipment, for transferring a heat from a heating portion in the electronic equipment to liquid refrigerant, is composed of a fin piece having a base portion formed thereon with thin fins which rise up from one surface of the base portion, being curved, and a casing accommodating therein the fin piece in its center part so as to cause the liquid refrigerant to flow between the thin fins. Further, the cooling device includes a plurality of heat receiving jackets and a plurality of heat radiating portions which are alternately connected so as to constitute a passage for the liquid refrigerant, a part of the passage being connected with a circulation pump so as to constitute a closed circulation passage for the liquid refrigerant. With this configuration, it is possible to provide a liquid cooling device capable of decreasing the temperature rise of a heating element such as a CPU, having a high performance and being excellent in costs.

Abstract: A flame retardant epoxy resin composition comprises a phosphorus atom-containing flame retardant polyester resin in addition to essential components of an epoxy resin and a curing agent. The phosphorus atom-containing flame retardant polyester resin is obtained by a condensation reaction or a polycondensation reaction of a reactive phosphorus-containing compound represented by the structural formula (I). By use of the phosphorus atom-containing flame retardant polyester resin as a halogen-free flame retardant, it is possible to achieve flame retardancy, reduce an amount of poisonous gas emitted when ignited, and improve moldability. In addition, a cured product of this epoxy resin composition is excellent in heat resistance, water resistance, chemical resistance, solder resistance, moisture resistance and tracking resistance as well as the flame retardancy.
