  • Patent number: 4778713
    Abstract: A wrapping paper thermosensitive recording materials comprising a light-reflecting paper layer which is located as the outer surface layer and a light-shielding paper layer which is located on the inside therefrom and which is integrally combined with said light-reflecting paper layer.The wrapping paper of the invention shields from the external heat and light. When internal humidity is increased such as by heating of the package such as at higher than 50.degree. C., moisture passes through the wrapping paper to the outside. Accordingly, fogging by precoupling of the wrapped thermosensitive recording materials remarkably decreased, and quality of the recording material could be maintained for a long period during storage.

  • Patent number: 4759977
    Abstract: A flexible carbon material is produced by carbonizing a composite material comprising carbon fibers having an average length of 6 to 50 mm and a binding agent. Carbon lumps are derived from the binding agent and are dispersed in a matrix of the carbon fibers so as to restrain a plurality of the carbon fibers while yet permitting relative slippage to occur as between the carbon fibers and carbon lumps such that the carbon fiber material exhibits a flexibility ratio D/d of not greater than 200 (where D is the diameter of curvature of the carbon material, when bent, just before breakage, and d is the thickness of the carbon material). The carbon fibers and lumps are preferrably present in an amount of from 5 to 50%, and 5 to 70% by volume, respectively, based upon the total volume of the carbon material.
