Abstract

1374124 Lamps MITSUBISHLDENKI KK 18 Oct 1971 [17 Oct 1970 21 Oct 1970 27 Oct 1970] 48414/71 Heading F4R [Also in Divisions F2 and H1] A light exposure apparatus for forming a fluorescent screen of a colour TV picture tube by exposure of a phosphor and photosensitive material comprises means for mounting a shadow mask, a point source of light 30, means defining an elongate slit 24 between source and mask, means for reciprocating the slit in a direction parallel to the face-plate for moving the exposed region of the faceplate progressively over the surface and means for moving the light source in a closed curve in synchronism with the slit movement. Figure 7 (not shown) includes cams 70, 72 effecting X-Y movement respectively of the source via rightangle member 56 and rods 62, 64 held in engagement by spring 74, the shaft 44 pivoting about bearing 46. Synchronized reciprocation of the slit is effected by a third cam 94 on the common shaft 44, via members 98 and 86. Pin 54 in slot 50 inhibits rotation of source 30 about shaft 44.
