  • Patent number: 5702810
    Abstract: The present invention relates to a cushioning composite molded article obtained by forming a cushioning material having a surface material on a rigid substrate integrally, and a process for producing the composite molded article by a simple procedure involving a small number of steps for production, andwhen a rigid-resin molded product is set in a mold and an expandable elastomer is injected, after which the inside of the mold is enlarged to expand the substance,the expanded elastomer becomes a cushioning material and its skin layer becomes a surface material, and the formation of them and the union in a body of them and the rigid substrate, i.e., the rigid-resin molded product can be carried out in one mold in succession, so that the production is easy and that labor and the production cost are saved.

  • Patent number: 4814227
    Abstract: To prevent the growth of aquatic animals and plants on the surfaces of underwater structures, the surfaces are covered with a protective adhesive sheet comprised of a copper-nickel alloy plate having a weight ratio of copper:nickel in the range of 100:0 to 80:20, a primer layer formed on the alloy plate, and a pressure-sensitive adhesive layer formed on the primer layer. Prior to applied the adhesive sheet, the surface to be protected is preferably cleaned and coated with a primer of the same composition as that of the primer layer of the adhesive sheet.
