    摘要： To improve dust removing performance and to prevent re-adhesion of dust in dust cleaner for removing dust adhering to the surface of an object such as a timepiece component by effecting blow-off dust removal and charge elimination by the use of a clean compressible fluid and an electric static ion eliminator. A clean compressible fluid is discharged from a clean compressible fluid nozzle to an object. When the object is an electro-statically charged article, an electric static ion mix clean compressible fluid containing electric static ions generated from an electric static ion eliminator is discharged to the object. It is possible to employ the structure wherein the object is set into a blow washing tray, and is moved up and down by the emission of the clean compressible fluid.

    摘要： Method for producing a gas separation membrane comprising a microporous support having provided thereon a non-porous coating layer. The method comprises melt extruding a thermoplastic crystalline polymer under particular melt-extrusion conditions to form a precursor in the form of a hollow fiber or flat film, coating the precursor as a support with a coating substance composed of a natural or synthetic substance capable of forming a polymeric layer which does not form pinholes upon subsequent drawing after solidification to form a coating layer on the surface of the support, and solidifying the coating layer. The support is annealed either before or after the cooling process, and this is followed by cold drawing and heat setting the support to form the gas separation membrane.
