Abstract: A raw material supplier manufactures raw material for a plastic substrate by means of a raw material manufacturing device. A disk presser manufactures a substrate from the raw material by means of an optical disk manufacturing device, manufactures an optical disk by laminating the substrate sequentially with the recording layer and the reflecting layer, and records predetermined information on the disk by means of an information recording device. The disk presser recovers a pure and lucent plastic substrate from a disk fallen into disuse, so as to supply the substrate to the raw material supplier.

Abstract: A device for wrapping an object of substantially cuboid shape with predetermined width, length and thickness having top and bottom faces opposed in a thickness direction, front and rear end faces opposed in a longitudinal direction, and right and left side faces opposed in a width direction, in a wrapping material fusible by heating.

Thus, the print will not disappeared even if a hands touches or water is adhered, and no bad influence will be given to the substrate material since the protective agent is excellent in quick-drying property.

Abstract: A transparent and conductive laminate that is substantially decreased in reactive defects, and a display filter, a heat-ray reflecting film and an electromagnetic wave-shielding film comprising the laminate are provided. The laminate includes a transparent substrate, a transparent conductive thin-film layer containing silver, and a protective layer containing a binder material and inorganic fine particles, wherein the transparent conductive thin-film layer is in contact with the protective layer. The generation of reflective defects can be outstandingly reduced. Therefore, a laminate superior in electromagnetic wave-shielding ability, heat-ray reflecting ability and visibility for a long period of time and products comprising the laminate can be obtained.
