  • One side surface molten metallic coating apparatus
    Patent number: 4246865
    Abstract: One side surface of a strip of metal is contacted with a surface of a molten metal bath which is locally raised under ultrasonic vibration whereby a continuous coating is attained on one side only.A tool for imparting the ultrasonic vibration to a bath is immersed near the bath surface and the ultrasonic vibrator connected to the tool is contained in hollow holding means dipped in the bath.In accordance with the apparatus of the present invention, the worn tool can be exchanged for a short time and the molten metallic coating on one side only of the strip of metal can be attained for a long time.

  • Method of forming patterned transparent electro-conductive film on the substrate of liquid crystal display
    Patent number: 4187340
    Abstract: A paste comprising particles of an inorganic oxide and a vehicle is printed on portions of a substrate which are not to be coated with a transparent electro-conductive film. A low valence oxide film of an electro-conductive metal oxide is deposited on the printed substrate by a vacuum deposition process. The resulting substrate is heated in an atmosphere containing oxygen, whereby the film is oxidized to form a transparent, highly electro-conductive film and the vehicle present in the paste is decomposed to yield a patterned, transparent electro-conductive film on the substrate.
