Abstract: PURPOSE: To prevent the deterioration in the quality of a film in flatness, smoothness, etc., even when a filler is added by cutting off a part of the filler whose average particle size is greater than that of the filler added to a thermoplastic resin by specified physical conditions. CONSTITUTION: A thermoplastic resin containing a filler of an average particle size of δ and of a standard deviation of 0.1δ or more is melted with an extruder. In this process, the molten resin, the filler, and media having properties in which the filtration precision η meets 2.5

Abstract: PURPOSE: To obtain a structure of a wire electrode having a high flexibility and hardly kinking with enhancement of a directivity and a tensile strength at break as well as increase of an electrode surface area. CONSTITUTION: In an electrostatic application casting device provided with a cooling roll 3 on which a plastic sheet material 2 in a molten state is casted and a wire electrode 4 to which a high voltage is applied, the wire electrode 4 is formed by weaving a plurality of metallic wires of 2-100μm wire diameter into one wire electrode 4 of 30-300μm outer diameter.

Abstract: PURPOSE:The amount of coating solution that is excessively applied onto thermoplastic resin sheets is measured with a metering bar that is revolving at a specific peripheral speed by contacting with the sheets, thus preventing the breakage of wire and the formation of scratch on the sheets. CONSTITUTION:A coating liquid of 0.2-100 cp viscosity is coated on one or both surfaces of undrawn or monoaxially stretched thermoplastic resin sheets with a thickness of over 150 microns excessively, then the amount is measured with a metering bar that is revolving under contact with the sheet at a peripheral speed of -10 to +10% higher than the running speed of the sheet. EFFECT:Bubbles in the coating liquid move along the metering bar to both edges of the sheet, thus preventing the occurence of defects due to voids at the center part.
