    摘要: In an electromagnetic clutch having a rotating component, groove portions (21a, 21b) are made on a surface of the rotating component to induce air flow during rotation of the rotating component. The air flow enhances radiation of heat from the electromagnetic clutch. It is preferable that the groove portion is formed at each of axial ends of a driving rotor or pulley (12) included as the rotating component in the electromagnetic clutch.

    摘要: A scroll-type refrigerant fluid compressor includes a fixed scroll having a first circular end plate from which a first spiral wrap extends, and an orbiting scroll having a second circular end plate from which a second spiral wrap extends. The spiral wraps interfit each other at an angular and radial offset to form line contacts defining a pair of sealed-off fluid pockets. An anti-wear plate is disposed on one end surface of the second circular end plate of the orbiting scroll that engages with the second spiral element of the orbiting scroll. An annular boss is formed at a central portion of the other end surface of the second circular end plate of the orbiting scroll. An inner end of a drive shaft is operatively connected to the orbiting scroll through a bushing which is rotatably disposed within the boss. An axial hole is centrally formed through the second circular end plate of the orbiting scroll. Mists of the lubricating oil suspended in the refrigerant gas in a central fluid pocket are conducted to an inner space of the boss via an air gap between the second spiral wrap and the anti-wear plate, fine reticular paths at the second circular end plate of the orbiting scroll beneath the anti-wear plate, and the axial hole.

    摘要: A porous membrane of vinylidene fluoride resin, including a 10 μm-thick portion contiguous to one surface thereof which comprises network resin fibers having an average diameter of at most 100 nm and shows a porosity A1 of at least 60% as measured by a focused ion beam-scanning electron microscope, and showing a surface pore size of at most 0.3 μm on said one surface thereof. The porous membrane has a treated water side surface layer showing a small surface pore size suitable for water filtration treatment and formed of extremely thin network resin fibers giving an extremely high porosity, thus showing an excellent minute particle-blocking performance and also extremely good anti-soiling resistance and regeneratability. The porous membrane is produced by a process including: melt-extrusion of a composition obtained by adding to vinylidene fluoride resin of a large molecular weight a relatively large amount of a polyester plasticizer which is mutually soluble with the resin and provides the resultant mixture with a crystallization temperature that is substantially identical to that of the vinylidene fluoride resin alone to form film, followed by cooling from one side of the film to solidify the film, extracting the plasticizer and stretching the membrane after the extraction while partially wetting a surface portion thereof.

    摘要: A porous membrane for water treatment of the present invention is made of a resin composition containing 100 parts by weight of a polyvinylidene fluoride based resin, and 5 to 13 parts by weight of a polyvinyl alcohol based polymer having a degree of saponification of 10 to 80 mol %. The porous membrane has a permeation wetting tension of 38 to 72 mN/m, and a tensile strength of 7 to 20 MPa, and thus is characterized by having the excellent mechanical strength and wettability. This is a porous membrane for water treatment essentially containing the polyvinylidene fluoride based resin, which allows water treatment to be highly efficiently performed on raw water (river water, industrial waste water, and the like), in particular. The porous membrane is manufactured, firstly, by melt-extruding a mixture composition containing a polyvinylidene fluoride based resin, a polyvinyl alcohol based polymer, a plasticizer, and a solvent, and then by extracting the plasticizer and the solvent from the substance thus extruded.
