Abstract

1448596 Colour television tubes SONY CORP 14 Nov 1973 [17 Nov 1972 (2)] 52811/73 Heading H1D In the photographic production of a phosphor pattern on the face plate 20<SP>1</SP> of a colour picture tube having an apertured mask 21<SP>1</SP> by projecting light from a source 24<SP>1</SP> on to the face plate first through correcting lens means 29 and then through the mask, the light source and mask apertures are rectilinear and the correcting lens means has a plurality of refractory surface sections having discontinuous (i.e. stepped) border lines each at an angle to the linear light source, the border lines may be at right angles to the light source, Fig. 7, or at an angle. In the latter case, they may be a single set, Fig. 11, or two sets, Fig. 13, of parallel lines.
