摘要： PROBLEM TO BE SOLVED: To provide a fin having an ultra hydrophilic surface or an ultra water repellent surface, its manufacturing method and a heat exchanger in which frosting is suppressed by providing that fin. SOLUTION: An ultra hydrophilic fin surface or an ultra water repellent fin surface can be obtained by forming fine irregularities in a hydrophilic or water repellent coating layer 2 on the surface of a basic material 1 by plasma irradiation. In a heat exchanger provided with such fins, frosting on the surface of fins is prevented as much as possible and in an air conditioner comprising such a heat exchanger, interruption of heating operation incident to defrost operation is substantially eliminated and comfortable heating operation can be realized. An ultra hydrophilic fin or an ultra water repellent fin can be produced inexpensively by a method comprising a first step for cleaning the surface of the basic material 1 by plasma irradiation, a second step for performing undercoating/corrosion proofing on the surface of the basic material 1, a third step for forming a hydrophilic or water repellent coating layer 2, and a fourth step for forming fine irregularities in the coating layer 2 by plasma irradiation.

摘要： PROBLEM TO BE SOLVED: To simplify the structure of a cam motor device in a cam motor device which does not require a variable speed. SOLUTION: A cam ring 3 and a cylinder block 2 are provided on the same axis and an output shaft 10 engages with the cylinder block 2. Eight radial cylinders 5 are formed in the cylinder block 2. A piston 6 is slideably provided in each cylinder 5. A working chamber 51 is formed in the cylinders 5. An end cap 4 is provided above the cylinder block 2. In this end cap 4, first and second supply and exhaust routes 43, 44 through which hydraulic fluid flows are formed. The hydraulic fluid is supplied and exhausted to the working chamber 51 through first and second distribution ports 41, 42. Also, the hydraulic fluid which is supplied to the working chamber 51 also flows in to a pressure concave portion 71a of a pressure plate 71. The pressure plate then presses down on the cylinder block 2 from the pressure of this hydraulic fluid, thereby controlling leakage of the hydraulic fluid.

摘要： PURPOSE:To keep off the worsening of sealability and prolong the life-time by installing a U-shaped seal ring in contact with an outer circumferential surface of a sliding member and an inner circumferential surface of a fixed member at the outside of this sliding member, and fitting a ring elastic sealing member in the inner part. CONSTITUTION:A sectional U-shaped seal ring 11 is interposed between a cylinder 1 as a cylindrical fixed member and a plunger 2 as a sliding member slidingly inserted to the cylinder 1 via a spacer 3, and a ring elastic sealing member 12 is fitted in this seal ring 11, thereby sealing up a superhigh pressure fluid. This seal ring is made up of a wear resistant material such as tungsten carbide or the like. With this constitution, this superhigh pressure water penetrated into the seal ring 11, pressing the elastic sealing member 12 under pressure, getting it elastically deformed in the radial direction, and thereby the seal ring 11 is forcibly pressed to the cylinder 1 and the plunger 2, thus sealability is secured.

摘要： PROBLEM TO BE SOLVED: To improve COP while maintaining a cooling capacity in an air conditioner using an air cycle. SOLUTION: A cycle side system 20 is formed by sequentially connecting a compressor 21, a heat exchanger 30, a water remover 22 and an expander 23 through a duct. The compressor 21 sucks indoor air and ventilating supply air and compresses them. The compressed air is heat-exchanged for ventilating exhaust air in the heat exchanger 30 and cooled. The moisture in the cooled compressed air is removed by the water remover 22. The water remover 22 is provided with a separate film to separate moisture in the compressed air without condensing it. Then, the compressed air is expanded by the expander 23 to become low temperature air and the low temperature air is supplied to a room. The exhaust air cooled in a humidifying cooler 41 is supplied tpo the heat exchanger 30. In the heat exchanger 30, the evaporative latent heat of water supplied in a humidifying part 42 is employed to cool the compressed air.

CONSTITUTION: In a rotary pump for a freezer wherein HFC fluorocarbon is used as a refrigerant and fluorocarbon oil is used as lubricating oil, powder high-speed steel (SKH-51) is employed as the body 24a of a vane 24 as a slide member and after the powder high-speed steel is sintered and molded in the shape of the vane of a rotary compressor, the surface of a slide part 24b on the tip side of the body part 24a is coated with a chrome nitride layer. Further, instead of the chrome nitride layer, a vanadium carbide layer, an acid nitride- oxide layer, a chrome oxide layer, and a teflon-contained chrome layer may be used. A substance prepared by fluorocarbon oil having a fluorine-containing aromatic compound or a fluorine-containing aliphatic compound is used as fluorine-based lubrication oil.

摘要： PROBLEM TO BE SOLVED: To ensure a sufficient heating capacity in an air conditioner for heating by using an air cycle. SOLUTION: A heat source side system 20 is formed by sequentially connecting a compressor 21, a heat exchanger 30, a water remover 22 and an expander 23 through a duct. The compressor 21 sucks outdoor air and ventilating exhaust air and compresses them. The compressed air is heat-exchanged for conditioning air in the heat exchanger 30. The moisture in the compressed air is removed by the water remover 22. Then, the compressed air is expanded by the expander 23 to have low temperature air and the low temperature air is exhausted outside a room. Conditioning air is supplied to the heat exchanger 30 through an inlet duct 43. This conditioning air is obtained by mixing ventilating supply air with indoor air.
