  • Patent number: 4572842
    Abstract: Method for reactive vapor deposition of compounds of metals and semi-conductors on at least one substrate by glow discharge. Into a space between a magnetron cathode (1) with a target (5) and the substrate (11) an inert gas and a reaction gas for the formation of the desired compound with the target material are separately introduced. Two solve the problem of making it possible to maintain the vapor deposition process stable over long time periods, according to the invention, a flow restriction is introduced between the target (5) and the substrate (11) by a diaphragm (20), which amounts to at least 40% of the cross-section of the space. Further, the inert gas is fed between target (5) and aperture (20) at the periphery of the target.

  • Patent number: 4548691
    Abstract: A method of producing glass sheets having good transmission behavior in the visible spectrum range and having good reflection behavior as regards heat radiation. A transparent substrate S is coated by cathodic atomization with, successively, a first oxide layer 1 comprising indium oxide, tin oxide or mixtures thereof, a layer 2 consisting of silver in a thickness of 5 to 50 n, a metallic layer 3 selected from aluminium, titanium, tantalum, chromium, manganese and zirconium in a thickness ranging from 1 to 5 nm and applied directly to the silver layer 2 for the purpose of maintaining the condition thereof, and a final protective oxide layer 4 of indium oxide, tin oxide or mixtures thereof.

  • Patent number: 4534841
    Abstract: Solar-controlled glazing having a transmission of between 5 and 40% in the visible spectrum range and having heat-reflection properties is produced by applying an oxide layer having an optical thickness of between 20 and 280 nm directly to a transparent substrate by cathodic evaporation in an oxygen-containing atmosphere to form a first layer. A chromium nitride layer having a geometric thickness of between 10 and 40 nm is then applied in an atmosphere consisting of inert gas and nitrogen to provide a second layer. An optical third dielectric layer may be applied to the second layer. The oxide layer is selected from oxides of tin, titanium and aluminium.
