  • Pyrolytic process for producing a band-shaped metal layer on a substrate
    Patent number: 4042006
    Abstract: A band-shaped metal layer useful as a resistance layer and/or a contact layer is pyrolytically deposited onto a cylindrical substrate by surrounding the surface of the substrate with a mixture of a thermally decomposable metal compound and a carrier therefor and substantially simultaneously heating only precise surface areas of the substrate, as by a laser beam, to a temperature slightly above the thermal decomposition temperature of the metal compound and moving the substrate in a rotational and/or axial manner so that a band-shaped metal layer forms only at the heated surface areas of the substrate.
