  • Electromagnetic wave-absorption multilayer substrate
    Patent number: 8043727
    Abstract: An electromagnetic wave-absorption multilayer substrate has an electromagnetic wave-absorption sheet which includes a soft magnetic alloy powder and a binding agent and two insulating substrates which have facing surfaces facing the electromagnetic wave-absorption sheet and which are pressure-bonded thereto. In addition, one of the insulating substrates has a plurality of holes formed in the facing surface.

  • Anti-plating agent for one-side hot-dip plating process
    Patent number: 4404030
    Abstract: Disclosed is an anti-plating agent for use in hot-dip plating process, having the following two kinds of composition. The composition of the first kind includes an alkali silicate; boric acid, and alkali hydroxide, magnesia and/or magnesium hydroxide, titania and/or titanium hydroxide, and at least one compound selected from a group consisting of alumina, aluminium hydroxide and alumina zol. The composition of the second kind includes an alkali silicate, boric acid, alkali hydroxide, magnesia and/or magnesium hydroxide, alumina and/or aluminium hydroxide, and at least one kind of titanium oxide and titanium complex oxide and/or at least one kind of zirconium oxide and zirconium complex oxide. These anti-plating agents have a good anti-plating effect and permit an easy separation of the coating film and, hence, can suitably be used in one-side hot-dip plating of steel sheets.

  • Method of producing one-side plated steel sheets or strips
    Patent number: 4125647
    Abstract: Anti-plating agents which form, after heated, compounds having a composition of(0.5-9.0)M.sub.2 O.SiO.sub. 2.(0.1- 7.2)B.sub.2 O.sub.3.(1.0- 34.5)MgOwherein M represents an alkali metal, are disclosed. An anti-plating film formed on the surface of a steel sheet by the use of the agent is excellent in the property for preventing the sheet from being plated and in the peeling property from the sheet, and the agents are suitable for production of one-side hot-dip plated steel sheets.
