Title: Method for producing images
IPC: G03C1/705
Filed: 1972-05-16
Abstract: 1397567 Photographic processes ENERGY CONVERSION DEVICES Inc 16 May 1972 [17 May 1971] 23006/72 Heading G2C A method of producing a relief image which comprises imagewise exposing a material comprising an inorganic layer on a support which is chemically inert with the layer which alters the adhesion of the layer for the support and physically removing the less adhesive areas to leave a relief image. Physical removal may be accomplished by (1) applying an adhesive tape, (2) an air blast, (3) bending the material or running the material over a small roller or (4) brushing, wiping, or abrading the material. The inorganic layer may be a Ge and/or Te composition or Se/S as disclosed in Specifications 1070411, 1070412 and 1283542 or Pb/Sn alloys; the compositions may be admixed with promoters e.g. metal halides, which promote the conversion of the layer from the amorphous to crystalline form which also generally occurs on exposure as disclosed in Specification 1364288. In the examples Te compositions containing Ge, S or As or Se/Ag are thermally evaporated on a glass or a polymeric support, imagewise exposed to flash or a laser beam and then an adhesive tape is applied to transfer the exposed areas thereto if a glass or rigid support is used but if a thermoplastic support is used, the unexposed areas are transferred. Alternatively, the material may be flexed over the sharp edge of a table to remove the unexposed areas. If a polymeric support is used, the bared areas of the support may be dissolved to produce a stencil (c.f. Example 5). The image on the adhesive tape may be made more visible by adhering it to an Al plate (Example 2) or applying it to a C paper, the C adhering to the adhesive areas (Example 7). Lithographic plates can be produced if an adhesive is sprayed on the exposed material, a hydrophilic plate adhered thereto and removed with the unexposed oleophilic areas adhering to the plate (c.f. Example 6). The relief images may be used as originals or electrical components as well as lithographic plates. If desired, the relief image may be rendered hydrophilic by application of AgNO 3 , SnCl 2  or nickel salts and both the relief image and transferred image may be used. A backing layer may be applied to the support and the bared support may be etched after formation of the relief image. The relief image may be produced by imagewise exposing the material to produce a latent image and then uniformly exposing (generally heating) to produce the change in adhesion and then physically removing the less adhesive areas.

The excitation of Ward- Leonard generator 2 supplying motor 1 is regulated in accordance with the difference between the output voltage of a tachometer generator 10 driven by the motor 1 and a reference voltage obtained from a potentiometer 9 connected across a constant voltage source and operated -directly or through a servo-device-by cam 4 driven at constant speed by an independent motor 5. Thus the motor 1 operates on a speed/time cycle determined by the shape of cam 4. The difference between the voltages is applied to the field winding 11 of an excitere.g., an amplidyne-for generator 2. The exciter may have an anti-hunting field winding. An electronic amplifier 12 may be used additionally or alternatively to the amplidyne and the amplifier or the amplidyne may be arranged to limit the motor speed, current, or applied voltage. In place of field winding 11 there may be two opposing fields, one supplied by potentiometer 9 and the other by generator 10. Motor 5 and cam 4 may be reversible, and they may be periodically stopped and re-started ; a circular part of the cam periphery may have notches or projections for operating pilot switches to stop the cam and to put the cam under the control of a timing device by which the cam is later re-started.
