Abstract: A method of manufacturing a both-side metallized insulation film comprises steps of: depositing zinc or a blend of zinc and aluminum onto both sides of an insulation film; and winding this metallized film into a product roll. The method is characterized in spraying an oxidizing gas onto a deposited layer on an inner side of the insulation film to be wound, during the winding step. During a vacuum deposition step, an oil layer is formed on at least one side of the metallized film. In addition, an oxide layer is formed by exposing a deposited layer on at least one side to oxygen, or by spraying an oxygen-containing gas onto the deposited layer on at least one side during the winding of the metallized film into the product roll.

Abstract: A metallized film capacitor formed from a pair of metallized films. Each of the metallized films includes a dielectric film with a metal evaporated electrode formed thereon. One electrode has longitudinal electrode partitioning lines and a plurality of small blocks separated by fuse areas, while the other electrode does not. Each metallized film is formed by moving the film over a screen cylinder having a side wall with openings formed therein. A nozzle is disposed inside the screen cylinder, adjacent to the side wall. Oil is ejected from the nozzle, while the screen cylinder is rotated. The oil passes through the side wall and is deposited on the film to form a pattern thereon. Subsequently, evaporated metal is deposited on the film.
