  • Method for manufacturing touch panel and molded article
    Patent number: 9597858
    Abstract: An object of the present invention is to provide a method for manufacturing a touch panel. A laminated film is used. The laminated film comprises a resin layer, a protection film-constituent material layer provided on a surface of the resin layer, and a releasing layer provided on a surface of the protection film-constituent material layer. The protection film-constituent material layer is a layer containing fluorine-based substances. The releasing layer is a layer made by using a fluorine-based resin. The method comprises a molding process, a hardening treatment process for providing hardening treatment to the protection film-constituent material layer after the molding process, and a removal process for removing the releasing layer after the molding process. The protection film-constituent material layer is an uncured layer in the course of a molding process.

  • Method of disposing of combustible materials
    Patent number: 6745707
    Abstract: A method of disposing of combustible materials. The method includes the steps of: providing a heating space; providing a first source to generate heat to a first predetermined level at a first location in the heating space sufficient to reconstitute the combustible materials to a molten slag at the first location and so that heat generated by the first source elevates the temperature at a second location within the heating space to a second predetermined heat level that is below the predetermined heat level and high enough to cause combustion of the combustible materials; directing combustible materials to the second location at which the combustible materials are combusted to produce ash; and causing the ash to be directed to the first location to be reconstituted as molten slag.
