Abstract: PROBLEM TO BE SOLVED: To make the temperature of a mouthpiece in its width direction uniform by inserting at least one heat pipe in the width direction of a mouthpiece in which a thermoplastic resin is molded in a sheet or film shape. SOLUTION: At least one heat pipe is inserted in the width direction of a mouthpiece at a land part molded to be a sheet shape after a resin is expanded in the width direction. The insertion of the heat pipe into the mouthpiece makes the temperature of the mouthpiece uniform. The insertion direction is fitted with the width direction of the mouthpiece, thereby reducing the temperature difference between the central portion and the edge portion of the mouthpiece. It is desired the number of the inserted pipe be generally about 2-20, since more pipes increase the effect of uniform temperature. The resin transferred to the mouthpiece is molded to be a sheet shape through the mouthpiece in which the heat pipe is inserted, and discharged. Use of the mouthpiece achieves the smaller temperature range in the width direction and the excellent thick controlling property in the width direction, so as to obtain a film with smaller thickness uniformity in the width direction.

Abstract: PROBLEM TO BE SOLVED: To provide a melt extrusion method capable of producing a sheet, a film, fibers, a molded product of a clean molten thermoplastic resin not containing thermally decomposed matter, gelled matter or foreign matter. SOLUTION: In a melt extrusion method supplying a thermoplastic resin to a melt extruder to melt and filter the same and extruding the filtered molten resin from a molding cap, the thermoplastic resin is molded while vibration is applied to the resin in the process from the melting process to the filtering process. The pressure of the molten resin in a vibration applying process is pref. set to a high pressure of 5 MPa or more. The thermoplastic resin is selected from a polyester, a polyolefin, polyphenylene sulfide and a polyamide.

Abstract: PROBLEM TO BE SOLVED: To provide a polyester film for capacitor dielectric by which the variation in the insulation resistance of capacitor can be reduced and the produc tion yield thereof be improved, by eliminating deterioration of insulation resis tance due to film, and a highly safety capacitor can be formed. SOLUTION: A film is made mainly of polyethylene terephthalate and is oriented biaxially. Its thermal deformation S90 at 90 deg.C in the lengthwise direction is represented by a formula, S90 =(L90 -L40 )/L40 ×100(%) (L90 : length of a film sample at 90 deg.C; L40 : length of film sample at 40 deg.C). In the this case, the thermal deformation S90 is 0 to 0.5.

SOLUTION: A molding cap 1 cools a thermoplastic resin of which the temp. is higher than melting completion temp. Tme to temp. below Tme and higher than temp. drop crystallizing start temp. Tcb in a land part 4 to mold the same. In this case, the thermoplastic resin is cooled by circulating a heating medium having temp. equal to or lower than the cooling temp. of the thermoplastic resin into the mouthpiece 1.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyester film for capacitor excellent in withstand voltage characteristic in high-temperature and long time load, hardly causing lowering of insulation resistance and excellent in productivity by specifying between residual amount of metal and phosphorus of the polyester film. SOLUTION: This polyester film has 0.8-4M/P [M and P each represent a residual amount (equivalent) of a metal (except antimony metal) and phosphorus in polymer], 0.1-2μm maximum roughness and 0.003-0.8-μm surface roughness Ra. Furthermore, the polyester film has a polyester (urethane)-based or an acrylic resin coating film on at least one side and uses a metal layer, especially a metallized polyester film on at leas one side.
