81	Corona-shield for an image-tube photocathode	US810122	1977-06-27	US4115722A	1978-09-19	Charles Bruce Johnson
A hollow cylindrical member composed of a high-voltage potting material is secured adjacent the photocathode to the high-voltage potting material encircling the image-tube. The hollow member is concentric with the axis of the tube and extends away from the photocathode. A plurality of equally spaced metallic discs are embedded in the potting material of the corona-shield interconnected by a plurality of resistors. A high-voltage is coupled to one of the metallic discs adjacent the photocathode and a ground is coupled to another of the metallic discs most remote from the photocathode.
82	Implosion-resistant cathode ray tube with protective assembly for its face plate	US635240	1975-11-25	US4031553A	1977-06-21	Hiroji Sumiyoshi; Tomosuke Chiba
A cathode ray tube having a metal reinforcing band girdling its envelope adjacent the face plate is provided with a transparent protective panel which covers the face plate and is affixed to the latter by a transparent conductive layer of an adhesive resin filling a space therebetween, and one or more conductive connecting elements providing an electrically conductive connection between the transparent conductive layer and the reinforcing band which is grounded. The transparent panel and the transparent conductive layer cooperate to protect the face plate from damage that might cause implosion of the tube envelope, and the connection of the transparent conductive layer to ground ensures that the protective panel will not be electrified, whereby to eliminate any shock hazard from contact therewith.
83	Mobile ion film memory	US643399	1975-12-22	US3995190A	1976-11-30	Francis John Salgo
A memory device and method is disclosed wherein positions of ions associated with a film are varied locally with respect to the film's surface by an electric field. A writing and erasing field is created by voltage modulating the film's conducting substrate in syncronization with low intensity electron bombardment of a local area of the film's surface by a scanning electron beam.The ion's position in the film varies the film's surface potential and alters the angular distribution imparted by its surface to primary diffracted and secondary emitted electrons. In the invention's read mode a scanning electron beam, combined with a detector discriminator, analyzes these emitted electrons to determine the surface potential at each address on the film thus reading out data stored in the film. A second means of reading out stored information utilizing detection of low energy electrons selectively diffracted by ions near the film's surface is disclosed.
84	Beam-index color television displays	US472154	1974-05-22	US3967315A	1976-06-29	David M. Goodman
Beam-index line-screen television display systems are disclosed for generating multi-color images throughout the size range from small direct view cathode ray tubes to projection type wall screen configurations. The image in the small screen display is generated by a scanning electron beam whereas the image generated in the large screen configuration is developed bY a scanning optical beam. In both cases the excitation of the image producing target screen is synchronized by beam-indexing features which utilize optical index signals transmitted across the target screen.
