摘要:
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.

An air conditioner includes a compressor, first and second heat exchangers connected with high pressure piping, low pressure piping connecting the second heat exchanger to a compressor suction port, a pressure reducing mechanism arranged to reduce pressure in the high pressure piping, a bypass passageway, a vessel connected to the bypass passageway, and first and second opening/closing mechanisms. The first heat exchanger is connected to a compressor discharge port. The bypass passageway is arranged to divert refrigerant from the high pressure piping to the low pressure piping without passing through the second heat exchanger. The first opening/closing mechanism is arranged to open/close a first portion of the bypass passageway that connects the high pressure piping to the vessel. The second opening/closing mechanism is arranged to open/close a second portion of the bypass passageway that connects an upper part of the vessel to the low pressure piping.

An air-conditioning apparatus includes first and second outdoor units having first and second outdoor heat exchangers and first and second heat source-side degree of subcooling adjustment devices configured to adjust first and second degrees of subcooling in outlet sides of the first and second outdoor heat exchangers, respectively. First and second outdoor-side determination units are configured to determine first and second degrees of subcooling, respectively. A controller is configured to control the first and second heat source-side degree of subcooling adjustment devices, respectively, such that a difference between the first degree of subcooling and the second degree of subcooling is reduced when refrigerant is charged into a refrigerant circuit having the first outdoor heat exchanger and the second outdoor heat exchanger.

A plating film is provided with enough hardness before anodic oxidation, which is hard to be damaged during handling, and also the production method of the plating film. This problem can be solved by an aluminum plating film with aluminum concentration of 98 wt. % or lower, and with a Vickers hardness of 250 or higher. Here, by containing oxygen, carbon, sulfur, and a halogen element as impurities, the hardness becomes higher. The impurity concentration is controlled by adjusting the current density, the plating temperature, or the plating bath composition.

A brush device having the longitudinal direction of a coil shaped coil spring aligned with the face of a brush holder, in which one end of a support post at the surface of a brush base is formed as a hollow cylinder and a projection at the other end is insert molded into the brush holder. There is a step on the support post. The step and the brush holder receive a cover plate which, when viewed from a direction perpendicular to the face of the brush holder, covers a winding of the coil shaped coil spring. One end of the support post is fixed to the surface of the cover plate by spreading the end of the hollow cylinder of the support post.

The present invention aims at making a motor with a brush in the direction of its motor shaft small by providing a thin brush device and at preventing deterioration of functions thereof. A guide portion is provided at a brush base portion and a recess portion is provided at the a brush holder. In the recess, an end portion of a winding portion of a coil-shape spring is held at the brush base portion, and the other end portion is held at the brush holder. Further, the longitudinal direction of the coil-shape spring is set so as to conform to the direction of face of the brush holder, and thereby the coil-shape spring and the brush are disposed on a substantially identical plane, having a state where the winding portion is placed along the guide and recess portion.

The present invention relates to a reproduction device of a holographic memory capable of precisely reproducing multi-value phase information without being influenced by noise. This holographic memory reproduction device comprises: a hologram diffraction ray generation unit which irradiates a first reference ray to the holographic memory and generates a diffraction ray of the first hologram; a hologram generation unit which changes the phase of a second reference ray which may interfere with the diffraction ray of the first hologram and generates a second hologram from the diffraction ray of the first hologram and the second reference ray to which the phase has been changed; a detection unit which detects the intensity distribution of the second hologram; and a processing unit which demodulates the phase modulation signal or the space quadrature amplitude modulation signal on the basis of the intensity distribution.
