Abstract: No studies have been made regarding what kinds of refrigerants should be used in a refrigeration cycle device for a vehicle. An air conditioner (1) for a vehicle includes a refrigerant circuit (10) and a refrigerant that is sealed in the refrigerant circuit (10). The refrigerant circuit (10) includes a compressor (80), a first heat exchanger (85), which serves as a heat dissipater in a dehumidifying heating mode, an outside-air heat exchanger (82), a cooling control valve (87), and a second heat exchanger (86), which serves as an evaporator in the dehumidifying heating mode. The refrigerant is a refrigerant having a low GWP.

Abstract: A showcase includes a refrigerant circuit and a refrigerant enclosed in the refrigerant circuit. The refrigerant circuit includes a compressor (121), a radiator (122), an expansion valve (123), and an evaporator (124). The refrigerant is a low-GWP refrigerant.

Abstract: Disclosed is a resin composition containing lignin and a phenol resin, the lignin being one resulting from separation of a cellulose component and a hemicellulose component from a decomposition product obtained by subjecting a plant raw material to a decomposition treatment, and the lignin and the phenol resin being mixed in a solvent. It is possible to provide a resin composition capable of being melt kneaded at low temperatures and having excellent processability and moldability, a production method for the same, and a molded product using the same.

Abstract: In accordance with the present invention, by using a resin composition including lignin and a curing agent in which the lignin is soluble in an organic solvent and contained in the resin composition in an amount of from 10 to 90% by mass, there are provided a molded product and a composite molded product which are obtained from plant resources as a main raw material and to which a good flame retardance and a good antibacterial property are imparted.

Abstract: A brazing sheet for flux-free brazing, comprising a core material, a brazing material disposed on at least one surface of the core material, and a thin skin material disposed on the brazing material, wherein the core material is made of an aluminum alloy having a higher melting point than that of the brazing material; the brazing material is made of an Al—Si—Mg based alloy and has a thickness of 25 to 250 ?m; the thin skin material is made of an aluminum alloy having a higher melting initiation temperature than the brazing material and containing substantially no Mg, and has a thickness of 5 to 30 ?m; and a content of an oxide existing at an interface between the brazing material and the thin skin material is 0.1 ppm or less in weight ratio with respect to the entire clad material. The present invention provides a brazing sheet for flux-free brazing, which has a thin skin material, with uniform brazing characteristics, and enables stable joining.
