摘要： Electrophotographic medium which comprises a transparent substrate, ohmic layer and coating of photoconductive material, all of which form a modulating structure for the radiant energy that is adapted to be projected through the substrate; a dielectric layer (storage medium) intimately bonded to the surface of the photoconductive coating and a conductive electrode in intimate contact with the dielectric layer. The structure is used by connecting a d.c. voltage across the outer electrode and the ohmic layer and projecting the image onto the electrophotographic medium from the bottom surface of the substrate. The charge image appears on the dielectric layer. The charge image is read out with an electronic beam or toned and fixed or transferred. During use the electrode is brought into intimate contact with the dielectric layer and removed after forming the charge image in order to enable the medium to be processed further without the electrode. The interface between the dielectric layer and electrode preferably is liquid, at least when originally formed, and may comprise a conductive fluid or organic or inorganic material or a low melting point metal that is easily stripped off the dielectric surface.

摘要： Method and apparatus for sputter coating of printing or similar type cylinders by means of r.f. sputtering in which each of the cylinders being coated comprises a thin, metal sleeve of cylindrical configuration mounted on a mandrel. A plurality of mandrels is mounted in a sputtering chamber on a spider which is rotated coaxially with a cylindrical target, the target being stationary. A fixed ring gear cooperates with pinions on each of the mandrels to impart an epicyclic movement to the mandrels, each of which mounts a sleeve.
