An electric valve is provided in a supply pipe. A flow rate control unit controls the degree of opening of the electric valve such that the flow rate in the supply pipe lies within a predetermined range, on the basis of a pressure difference between pressure of refrigerant supplied to the supply pipe and the pressure of refrigerant on the suction side of a compressor. An outdoor air temperature sensor detects outdoor air temperature; and a low-pressure side pressure sensor detects refrigerant pressure on the suction side of the compressor. The pressure difference is a difference between a saturation pressure corresponding to the outdoor air temperature detected by the outdoor air temperature sensor and refrigerant pressure detected by the low-pressure side pressure sensor.

An object of the present invention is to provide a method for producing a high-ductility, high-purity aluminum foil at a high film formation rate by electrolysis using a plating solution having a low chlorine concentration. A method for producing an aluminum foil of the present invention as a means for achieving the object is characterized in that an aluminum film is formed on a surface of a substrate by electrolysis using a plating solution at least containing (1) a dialkyl sulfone, (2) an aluminum halide, and (3) at least one nitrogen-containing compound selected from the group consisting of an ammonium halide, a hydrogen halide salt of a primary amine, a hydrogen halide salt of a secondary amine, a hydrogen halide salt of a tertiary amine, and a quaternary ammonium salt represented by a general formula: R1R2R3R4N.X (wherein R1 to R4 independently represent an alkyl group and X represents a counteranion for the quaternary ammonium cation), and then the film is removed from the substrate.

The present invention causes spatial-mode light emitted from an optical fiber (11), which is a multimode fiber, to pass through a photorefractive medium (13). The photorefractive medium (13) includes holograms for signal separation that are written by irradiation of the photorefractive medium with (i) guide light having a wave front identical to the wave front of signal light having a particular spatial mode and (ii) control light. The photorefractive medium includes holograms recorded in a multiplex manner with use of control light having different incidence angles in correspondence with respective spatial modes. For signal separation, irradiating the photorefractive medium (13) with control light (15) having a particular angle separates signal light having a spatial mode corresponding to the incidence angle of the control light (15).

An object of the present invention is to provide a catalyst exhibiting excellent performance particularly in partial oxidation reaction. Another object is to provide a method for efficiently producing carboxylic acid or carboxylic anhydride through vapor-phase partial oxidation of an organic compound by use of an oxygen-containing gas in the presence of the catalyst. The catalyst contains (1) diamond; (2) at least one species selected from among Group 5 transition element oxides, collectively called oxide A; and (3) at least one species selected from among Group 4 transition element oxides, collectively called oxide B. The method for producing a carboxylic acid or a carboxylic anhydride includes subjecting an organic compound to vapor phase partial oxidation by use of an oxygen-containing gas in the presence of the catalyst, wherein the organic compound is an aromatic compound having one or more substituents in a molecule thereof, the substituents each including a carbon atom bonded to an aromatic ring.
