Abstract:

1. A television camera tube comprising an elongated envelope, an electron gun in one end of said envelope for producing an electron beam, a target electrode in the other end of said envelope and in the path of said beam, said target electrode comprising a transparent conductive coating, a N-type photoconductor on said coating, a P-type photoconductor on said N-type photoconductor, another N-type photoconductor on said P-type photoconductor, a rectifying junction formed between each adjacent pair of said photoconductors and means for applying a reverse bias across at least one of said junctions.

International Classification:

G03G 1300

US Classification:

317262A

Abstract:

An original electrostatic charge pattern on an electrically insulating image-bearing surface is reproduced, on an electrically insulating film, in an intensified form by the steps of: A. placing one surface of the film in contact with the original charge pattern on the image-bearing surface, B. wiping, with a grounded wetted sponge, the other surface of the film to induce thereon a monopolar charge pattern of opposite polarity to that of the original charge pattern, C. separating the film from the image-bearing surface and wiping, with a grounded wetted sponge, said one surface, whereby to induce a bipolar charge pattern on the film, D. disposing said one surface of the film in contact with the image-bearing surface so that the electrostatic charge patterns of the same polarities contact each other and are in register with each other, E. wiping, with a grounded wetted sponge, said other surface of the film to induce thereon a monopolar electrostatic charge pattern superimposed on the bipolar charge pattern, and F. repeating the steps (c), (d), and (e), if necessary, until the reproduced electrostatic charge pattern on the film is of a desired intensity.

Appl. No.:

5/661614

Inventors:

Albert Rose - Princeton NJ

Assignee:

RCA Corporation - New York NY

International Classification:

H01J 2945
H01J 3138

US Classification:

313385

Abstract:

A substantially flat body of a photoconductive semiconductor material is coated on one surface with an electrically conductive layer. A layer of a solid insulator material is on another surface of the semiconductor material. The insulator material is of the type having mobile deep lying carriers and forms a blocking junction with the semiconductor material. The insulator material may be an electronically conductive glass, an ionically conductive glass, or a cermet composition. The photoconductor can be used as a target for a camera tube, or as an electrophotographic plate.

International Classification:

H01L 3106

US Classification:

136250

Abstract:

A semiconductor device in which particles of semiconductive material extend as separate chains from respective first and second contacts. When one of the contacts is of p-type material, the conductive materials that extend from it are of likewise p-material. Similarly, when the contact is of n-type material, the chain that extends from it is also of n-material. In any case the particles can include both p-type and n-type. One of the contacts can have a prescribed work function and the other contact have a lower work function in order to produce a prescribed junction between the two contacts. In addition the contacts may be polymeric. The particulate bodies may range in size from 10 to about 3000 angstroms in diameter. The n-type particles provide a continuous path for electrons and the p-type particles provide a continuous path for holes. The particles are adhered to one another by an inorganic or organic binder, pressure, heat treatment or thermal fusion.
