摘要： PROBLEM TO BE SOLVED: To enable a laminated organic capacitor to obtain a stable withstand voltage and a stable insulation resistance by denaturalizing inward vacuum- deposited aluminum films constituting electrodes into an aluminum oxide over a specific thickness. SOLUTION: A rectangular parallelepiped body is formed by alternately laminating areas composed of electrodes formed of dielectric layers 1 consisting of organic films having thicknesses of 0.05-3.5 μm and areas composed of margin sections formed of vacuum-deposited aluminum or aluminum alloy films 3 having thicknesses of 10-32 nm. The metal of the electrodes are denaturalized inward into an aluminum oxide or aluminum alloy oxide from two electrode leading-out layers connected to the electrode faces of the four laminated surfaces of the rectangular parallelepiped body and the other two laminated surfaces over a thickness of 0.5-200 μm. In denaturalization, a mixed gas which has a partial pressure ratio of 1/20 to 3/4, is composed of steam and air, and is maintained at >=100 deg.C is brought into contact with the laminated surface on which the aluminum is exposed for 5 seconds to 120 minutes.

摘要： PURPOSE:To prevent blocking by blowing an oxidizing gas into a film winding booth in a vacuum chamber when a metal such as Zn is vacuum-deposited on a synthetic resin film. CONSTITUTION:When a metal such as Zn or Al is vacuum-deposited on both the front and rear sides of a substrate (a) having >=45dyn/cm tension in a wet state, e.g. a synthetic resin film to produce a double vacuum-deposited film, a vacuum chamber 1 is divided into a vacuum deposition booth and a winding booth with partition walls 6, 7, and an oxidizing gas such as air is fed into the winding booth to oxidize only the metal vacuum-deposited on the film (a). By this method, the abnormal oxidation of the vacuum-deposited film and the shortening of the service life of crucibles for melting the metal for vacuum deposition can be prevented.

摘要： PURPOSE:To miniaturize a film capacitor, and to simplify a manufacturing process by using an electrode leading-out section formed through metallic spraying as an external electrode, thermally treating the surface of the external electrode at a high temperature and polishing the surface of the external electrode. CONSTITUTION:A capacitor element is thermally treated, and the surface of an external electrode is polished. That is, Al is vacuum-deposited on a PPS film and an electrode is formed, the electrode is slitted in width of approximately 5mm, the electrodes are laminated and a long sized element 4 is prepared, and solder is flame-sprayed onto both end faces of the element 4, thus shaping electrode leading-out sections. The whole is thermally treated for approximately five hr at 200 deg.C, and unpolished surfaces 7 in the electrode leading-out sections 2 are removed by a grinder 5, and novel surfaces 6 are obtained. The long sized element 4 is cut by a milling cutter, and a capacitor element 1 with cut surfaces 3 is shaped. When a capacitor acquired in this manner is dipped into a solder tank, the whole surfaces of the electrode surfaces 6 are coated with nevel solder, thus obtaining the electrodes having excellent solderability.

摘要： PURPOSE:To increase breakdown strength by executing heat treatment through which polyphenylene oxide (PPO) is crosslinked with a film capacitor element. CONSTITUTION:Evaporated electrodes composed of aluminum are formed onto both surfaces of a dielectric film consisting of PPS, and coating dielectrics made up of PPO are shaped onto the electrodes. A double-side evaporated double-side coated film is prepared. The double-side evaporated double-side coated films are laminated, and metallicon layers composed of zinc, etc., are shaped onto both end faces of the films, thus manufacturing a mother capacitor. The mother capacitor is heated, the temperature of the motor capacitor is elevated, a residual solvent for the coating dielectric is removed, and PPO is crosslinked through heat treatment. The mother capacitor is aged, and milling- cut, thus manufacturing a capacitor element. A comb lead is welded, molding sheathing is executed by using an epoxy resin, and the comb lead is worked, thus acquiring a capacitor as an external electrode.

摘要： PURPOSE:To improve heat-insulating properties by executing pressure heat treatment through which a capacitor element is pressed at a high temperature. CONSTITUTION:Aluminum is vacuum-deposited onto both surfaces of a polyphenylene sulfide (PPS) film and an electrode is formed, and polyphenylene oxide films are shaped onto both surfaces of the electrode through coating, thus preparing a long-sized double-side evaporated and double-side coated film in 5mm width. The films are laminated, and zinc is flame-sprayed onto both end faces of the laminated films and an electrode leading-out section is shaped. A temperature is elevated and the whole is heated, and pressure heat treatment for thirty min at a temperature of 230 deg.C or more is executed under the state is which pressure of 300g/cm or more is applied. A capacitor element is prepared through milling cutting from a mother capacitor under the state, and molded and sheathed, thus preparing a chip type film capacitor.

摘要： PROBLEM TO BE SOLVED: To maintain the effect of preventing the deposition of a vapor depositing material on masking tape over the long length by retaining the distribution of the molecular weight of oil for preventing vapor deposition in the longitudinal direction. SOLUTION: As oil for preventing vapor deposition, liq. paraffin with molecular weight in the range of 194 to 562 is used. In the case the oil is evaporated by an evaporator, there is a tendency that the evaporation occurs from the low molecular part at first, and it deposits on masking tape, and by the deposition of the one with molecular weight part from 194 to 392 suitable for application on the tape, the effect of screening a vapor depositing material can be obtd. Oil on the high molecular side from 392 not only has the effect less, but also has the tendency to remain in the evaporator and cause sudden evaporation. Thus, fresh oil is fed by the amt. to be required, an oil exhausting mechanism is added on a space between the oil evaporator and an exhausting tank, and the amt. same as that to be fed is exhausted, by which the oil in the molecular weight part (from 194 to 392) in the range effective for screening the vapor depositing material can easily be maintained in the longitudinal direction.
