Abstract

889,313. Cathode-ray storage tubes. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 15, 1959 [Dec. 22, 1958], No. 42529/59. Class 39(1) [Also in Group XXXVI] In a cathode-ray storage tube with a photoconductive target and a low velocity read out scanning beam and capable of storing half tones the charge image is retained e.g. for 1 to 10 minutes with conventional television scan rate, by providing the photo-conductive layer 15 of antimony trisulphide on a layer 13 comprising a mixture of arsenic and selenium. Layer 16 is a transparent conductive layer, e.g. stannic oxide. The ratio by weight of selenium to arsenic may be 2 : 1 or 1 : 1 and the layer 13 is at least 5 microns thick. An homogeneous arsenic-selenium mixture is first evaporated on to the target, the target taking on a deep amber or slightly red colour. The antimony trisulphide is then evaporated on to a similar thickness, a deeper amber colour being obtained. The charge image may be laid down by a light signal or, if a conversion phosphor layer is added, by X-rays, or by the electron beam.
