摘要： A scroll compressor includes a crankshaft, a suction chamber, a back pressure chamber, a communication path, a back pressure control means, and a base plate. The base plate intermittently connects the communication path by opening and closing an opening on a back pressure chamber side of the communication path. The crankshaft drives an orbiting scroll, and mutually engages a stationary scroll having a whirlpool shape and the orbiting scroll.

摘要： A scroll compressor contains a suction chamber and a compression chamber formed between the orbiting scroll and stationary scroll; and the rear surface of the orbiting scroll includes a back pressure chamber to apply a pressing force for pressing the stationary scroll to the orbiting scroll by the pressure higher than the pressure in the suction chamber. The stationary scroll contains the communication paths 200, 201 to connect the suction chamber or the compression chamber and the back pressure chamber; and a back pressure control means for opening and closing the communication paths by way of the pressure differential along the communication paths. The inlet communication path 200 that extends from the back pressure control means to the back pressure chamber includes at least two or more path cross-sectional areas. The cross-sectional area of an inlet communication path 301 on the back pressure chamber side of this inlet communication path is formed larger than the cross-sectional area of an inlet communication path 302 on the back pressure control means side. Moreover, the opening surface area of the back pressure chamber side of the communication path 301 is configured so as to be constantly equal to or smaller than the cross-sectional area of the communication path 302 so that a section of the back pressure chamber side opening 300 of the communication path 301 is constantly blocked by the base plate of the orbiting scroll, and in this way a highly efficient and highly reliable scroll compressor is achieved.

摘要： Method for producing a synthetic fiber substantially comprising dissolving a composition consisting essentially of:A. 5-40 percent by weight of a copolymer consisting ofA. 20-80 percent by weight of polyvinyl alcohol, andB. 80-20 percent by weight of acrylonitrile, andB. 60-95 percent by weight of a copolymer consisting ofC. 55-95 percent by weight of styrene, andD. 5-45 percent by weight of acrylonitrile, in dimethyl sulfoxide or dimethyl acetamide as a solvent, and wet-spinningThis fiber is used for producing paper and has a potentially fibrillar texture. When beaten, it forms a synthetic pulp having stalk fibrils and micro fibrils extending from the stalk fibrils.High-tenacity synthetic paper can be made because this synthetic pulp is self-adhesive.

摘要： The electrostatic recording material comprises an electroconductive transparentized base sheet having a dielectric layer thereon. The transparentized base sheet is obtained by subjecting to a transparentizing treatment with moisture, heat and pressure a fibrous matrix sheet of a mixture of natural pulp with synthetic pulp formed of a blended polymer system consisting essentially of polyvinyl alcohol-acrylonitrile copolymer and acrylonitrile-styrene copolymer.
