A continuous network of lines of a metal or alloy with electrical conductivity at least 5·106 S·m?1 is on a substrate surface. The metal lines have an average width between 0.05 and 3 ?m. These metal lines delimit non-metalized fields of average equivalent diameter between 0.1 and 7.0 ?m. At least 20% of the metal lines' surface has a tangent forming an angle between 15 and 75° relative to a substrate-electrode plane. A transparent or translucent layer completely covers the metal lines and non-metalized fields. The layer has refractive index between 1.6 and 2.4 and resistivity greater than that of the metal lines and less than 104 ?·cm. The metal lines and the transparent or translucent layer form a composite layer called an electrode layer.

Abstract: A method for coating a substrate, preferably of glass, with a pyrolyzed transparent, electroconductive layer. The coating is comprised of indium formate, optionally mixed with a powdered or gaseous tin compound or a gaseous organotin compound. The coating layer is deposited upon a hot substrate whereupon it pyrolytically decomposes, forming a layer which is subsequently heat treated in a reducing or an oxidizing atmosphere to optionally enhance the low emissivity and low resistivity of the coating or reduce said low emissivity and low resistivity properties.

Abstract: A plurality of injector elements are mounted on a frame and within a nozzle above a subjacent support for depositing a layer of pulverulent product on the support. In order to change the predetermined spacing of the injectors, they are selectively connected to a shuttle which is moved by a digitally controlled stepping motor to a predetermined position, after which they are separated from the shuttle. A solenoid mounted on each of the injectors can be activated to frictionally hold the injector at its predetermined position.
