| abstract | 1366839 Image pick-up tubes MATSUSHITA ELECTRONICS CORP 20 March 1973 [24 March 1972] 13398/73 Heading H1D A method of manufacturing a colour TV camera tube comprises forming a transparent conductive film and a photoresist film 15 successively on a fibre type face plate 11, which may have a concave inner surface, corresponding to the focal surface of the electron beam, selectively exposing the resist to light transmitted through the faceplate and an optical mask 16 on the outer surface of the faceplate and developing the resist to form narrow apertures in the resist, etching the conductive film to form stripe-shaped narrow apertures, removing the resist, superimposing a photoconductive film and disposing an optical filter having stripes for generating an indexing signal corresponding to the narrow apertures on the outer surface of the faceplate. Alternatively after development of the resist, a photoconductive film may be superimposed without removal of the resist, and an optical filter having stripes for generating an indexing signal corresponding to the stripeshaped resist, disposed on the outer surface of the faceplate. The conductive film may be tin oxide, resists are referred to by trade names, light 17 may be <3500 Š and via a collimator, and the photoconductive material of antimony sulphide or lead monoxide for example. The process, in which light is passed through the faceplate, is stated to overcome the effects of fibre plate shear distortions of 10 to 30Á and optical filter stripes of 20Á require overall high resolution. |
