  • Patent number: 5686178
    Abstract: An article comprising a non-conductive substrate, preferably of an environmentally degradeable character, having a thickness of an oxidizable metal coating thereon, and optionally an oxidation enhancingly effective amount of a salt, e.g., from about 0.005 to about 25% by weight of salt, based on the weight of oxidizable metal, present on the oxidizable metal coating. Also disclosed is a related method of forming such article, comprising chemical vapor depositing the oxidizable metal coating on the substrate. When utilized in a form comprising fine-diameter substrate elements such as filaments, the resulting product may be usefully employed as an "evanescent" chaff.

  • Patent number: 5672414
    Abstract: A metallic printed board is formed by laminating an insulation layer on the surface of a metallic sheet as a base, and then electronic parts are mounted on the conductor pattern formed on the surface of the insulation layer. A double-sided printed board mounted thereon electronic parts is placed in parallel. Both the printed boards are supported and fixed monolithically by filling the space between the printed boards with an insulation resin and curing the resin. Furthermore, an insulation resin is laminated on the surface of the printed board in such a manner that the resin may cover the mounted electronic parts, and cured. The heat generated from the electronic parts can be efficiently transmitted to the insulation resins by using a resin having a high thermal conductivity for both of the insulation resins, and the heat is then emitted from the surfaces of the metallic sheet or the insulation resin.
