Abstract: The present invention is intended to lessen the noises made in the motor-driven hermetic compressor adapted to be installed in an electric refrigerator. The refrigerating machine oil held on the upper surface of the cylinder block by an effect of the drip-preventing wall flows out of the oil discharge portion regularly. Thereby, it is possible to control the returning route of the refrigerating machine oil to the bottom portion of the hermetic enclosure. The dripping of the oil droplets from the edge portion of the cylinder block is prevented to avoid the generation of the collision sound generated by the colliding of the droplets against the splashes of the oil splashed by the revolving of the oil feed pipe.

Abstract: A sealed compressor for use in a refrigerator includes a sealed housing having an interior communicated to the outside of the sealed housing through a discharge tube, a compressor element accommodated within the sealed housing, an electric element accommodated within the sealed housing for driving the compressor element, and a coupling tube fluid-connecting the compressor element and the discharge tube within the sealed housing. To avoid a resonant motion of the coupling tube which would otherwise generate obnoxious noise, an inverter controller is employed to allow the electric element to be operated at one of a plurality of frequencies other than the resonance frequency of the coupling tube.

Abstract: When a lock detecting means (17) detects a locked state of a DC motor (4) in a starting stage, a torque increasing means (18, 27, 29 or 31) immediately selects a starting sequence pattern of an output torque that is greater by one step, and outputs the same to a starting sequence control means (13), so that a compressor (5) can be restarted speedily without repeating starting failures. A compressor (41), driven by a DC motor (43), has a shell of an internal pressure approximately equal to the pressure of an inhalation gas. An inverter (53) is provided to make the speed of the DC motor (43) variable. A rotational frequency setting circuit (56) sets the rotational frequency of the DC motor (43) to a frequency that is not greater than the frequency of a commercial power source when the internal temperature of a refrigerator is stabilized.

Abstract: An insulated structure is produced by mixing a starting material of a foamed thermal insulating material comprising a polyol, a foam stabilizer, a blowing agent containing at least a hydrocarbon as one component, and an organic polyisocyanate with a halogen-free hydroxylated organophosphorus compound having a molecular weight of at least 150 as an additive, foaming the resultant mixture into a foamed thermal insulating material (4), and cast molding the material (4) in the space between a plastic facing (2) and an iron plate (3) provided with a copper pipe (5). The use of the above-specified organophosphorus compound serves to achieve a burning velocity equivalent to that attained by the use of the conventional blowing agent CFC11, to exclude the possibility of the corrosion of the pipe (5) in the structure caused by the dissociation of the phosphorus compound, to prevent the phosphorus from migrating into the facing (2), and to get rid of the fear of food staining.

Abstract: This invention relates to an expanded heat-insulating material containing a reduced amount of a fluorocarbon blowing agent for use in a freezer, refrigerator or the like. It is produced by stirring a mixture of a carbon dioxide adsorbent having a hydrophobic surface, a premix component containing water, and an isocyanate component. According to the expanded heat-insulating material thus produced, the amount of the fluorocarbon blowing agent to be used can be reduced since water is used as the blowing agent, while carbon dioxide generated by the reaction of the isocyanate with the water can be removed after foaming by adsorption with the carbon dioxide adsorbent, and the gas present in the bubbles becomes enriched with the fluorocarbon gas.
