    Abstract: PROBLEM TO BE SOLVED: To reduce a friction coefficient of a sliding part having high possibility of causing abrasion among a connecting rod, a main shaft, and a piston pin due to an increase in friction coefficient. SOLUTION: This hermetic compressor is provided with the connecting rod 58 transmitting the rotation of a crankshaft 54 to a piston 57, and the piston pin 59 connecting the connecting rod 58 to the piston 57. The friction of the sliding part can be reduced by disposing a coating material 1 having a low friction coefficient in the crankshaft 54 and the sliding part of the connecting rod facing the piston pin 59.

    Abstract: PROBLEM TO BE SOLVED: To achieve a protection of a conducting material by coating the surface of the conducting material with a rustproof material to an insulated part from a sealed part in a radiation type tube heater to be carried on a refrigerator, in which both end parts of a glass tube are sealed up to inject a waterproof and moisture-proof material to the end of an insulating member from the end of the glass tube. SOLUTION: A sealed part 6 is provided at both ends of a glass tube 2 and a molybdenum foil 7 is arranged in the sealed part 6. A tungsten wire as heater wire, an external heater wire and a molybdenum wire 8 with the same thermal expansion coefficient are welded on the foil. The molybdenum wire 8 is welded on an external lead-in wire 10 through a nickel wire 9. Paraffin is injected into the part of the molybdenum wire 8 as waterproof material 11, silicon 12a and 12b are injected into the glass tube and a rubber cap and the surface of the conducting material is coated with a rustproof material to an insulated part from the sealed part.

    Abstract: PURPOSE:To form an oil basin, and suppress the abrasion between a vane and a vane groove by forming a recessed part in the vane groove making contact with the vane constituting a compression element in a compressor having an electric element, the compression element, and an oil feeder housed 4n a sealed vessel. CONSTITUTION:An electric element 4 consisting of a stator 2 and a rotor 3 and a compression element 5 driven thereby are housed in a sealed vessel 1, and an oil 6 is also stored in the bottom part. When a crank shaft 14 is rotated according to the rotation of the rotor 3, a coil spring housed in a feed oil pipe 18 is rotated to feed the oil 6. On the other hand, a vane 12 is housed in a vane groove 12A formed on a cylinder 7, and pressed onto a roller 11 by a spring 13 to partition a compression chamber 10 into high and low pressure sides. In this case, the vane groove 12a making contact with the vane 12 has a recessed part 27 formed thereon. An oil basin is formed by utilizing the recessed part 27 to suppress the abrasion between the vane 12 and the vane groove 12A.

    Abstract: PURPOSE:To well lubricate a compressor mechanism by winding a part of a precooling pipe over the outer circumference of a refrigerant intake pipe so as to cover the outer surface of the refrigerant intake pipe, and thereby preventing high pressure refrigerant at the surface of the refrigerant intake pipe from being condensed so as to be liquefied. CONSTITUTION:In the inside of the sealed container 4 of a compressor 1, a part of a precooling pipe 14 is winded over the surface of a refrigerant intake pipe 11. In this case, a refrigerating cycle is made up of a circulating cycle composed of the delivery pipe 12 of the compressor 1, a precooling heat exchanger, a precooling pipe 14, a condensor, a capillary tube, an evaporator and the intake pipe 11 of the compressor 1. In this constitution, the intake pipe 11 is covered by the precooling pipe 14, so that heat excahnge is also performed. This constitution thereby allows low pressure refrigerant to be heated at the joint section 20, temperature is raised in a range from the intake pipe 11 out of the joint section 20 over to a compression mechanism 2, therefore high pressure refrigerant will never be condensed.

    Abstract: PURPOSE:To prevent the condensation of high pressure refrigerant through the rise of inlet pipe surface temperature and low pressure refrigerant temperature by providing a part of a precooling pipe with an expansion chamber for lowering the mass speed of circulating refrigerant, and forming this expansion chamber into a double pipe. CONSTITUTION:A refrigerating cycle is formed into a circulating cycle of the discharge pipe 12 of a compressor 1 a precooling heat exchanger 15 a precooling pipe 14 condenser 16 a capillary tube 17 an evaporator 18 a compressor 1. In such constitution, the precooling pipe 14 is partially expanded, and an inlet pipe 11 is passed therein to form an expansion chamber 20 of double pipe structure for lowering the mass speed of circulating refrigerant. The precooling pipe 14 therefore covers the inlet pipe 11 and performs heat exchange, so that low pressure refrigerant is heated at the double pipe 20 part, and its temperature rises in the inlet pipe 11 from the time of coming out of the double pipe 20 until reaching compression mechanism 2. High pressure refrigerant is thereby prevented from being condensed.

    Abstract: PURPOSE:To use ice for excellent drink by superposing an icemaking tray in a heat insulation tank in which a high frequency wave generating coil is arranged in an inner bottom. CONSTITUTION:An icemaking tray 29 is superposed in a heat insulation tank 24 in which a coil 28 for generating a high frequency wave is arranged in an inner bottom by opening an upper surface of one partition of a cooling chamber. When a predetermined quantity of water in a feed water tank is supplied into the tray 29 through a feed water tube 39, the water is frozen on one direction from a surface of the water downward with chilled gas in the cooling chamber by heat insulation of the tank 24 and heating of the high frequency wave from the coil 28 of the lower surface, and ice crystal is generated while discharging gas component and impurities in the water downward in the water. The component and the impurities are collected in the bottom of the tray 29 and frozen. Accordingly, an opaque part is concentrated at a small position, and transparency is increased as an entire ice. Thus, ice being excellently functional for drink can be used.
