摘要： Electrophotographic medium which comprises a multilayer structure of materials for imaging radiant energy patterns at high speed comprising a transparent substrate, ohmic layer and coating of photoconductive material, which form a modulating structure for the radiant energy projected through the substrate; a dielectric layer intimately bonded to the surface of the photoconductive coating and a conductive electrode in intimate contact with the dielectric layer. The dielectric layer constitutes the storage medium for the image which is produced in electrostatic charge form and, the medium is capable of retaining latent images for a very substantial length of time.The use of the electrophotographic medium does not require initial charging; hence no means for effecting this are required. Further, the speed of the medium is so high compared with all other media that extremely low energy levels can provide sufficient contrast to produce images.The structure as described is used by connecting a d.c. voltage across the outer electrode and the ohmic layer and projecting the image onto the medium from what would be considered the bottom surface of the substrate. The charge image appears on the dielectric layer. The information represented by the latent charge image is utilized by reading the same out with an electron beam or by toning and/or fixing and transfer.

摘要： A method for charging an electrophotographic member which includes rotating a number of elongate corona electrodes, which are positioned parallel to and a predetermined distance from a central axis, about the central axis while simultaneously applying a corona voltage to each of the electrodes whereby each develops a corona, so that a substantially uniform corona charge is applied to the entire electrophotographic member. An additional step, performed simultaneously with production of the corona and rotation of the electrodes, can be the movement of one of the rotating electrodes and the electrophotographic member relative to the other with a predetermined distance being maintained between the member and central axis. Apparatus employed to perform this method also is disclosed.

摘要： In a sputtering chamber where there is at least one target of some material comprising at least two elements which are to be sputtered as a compound onto a substrate within the chamber, a target having a plurality of edges is framed by a metallic shield to confine the sputtering to a forward direction and the background gas needed for maintaining stoichiometry of the sputtered material is injected directly inside of the shield so that immediately upon entry into the chamber a substantial portion thereof flows over the target. A perforated manifold running the length of an edge of the target releases the background gas to the target along its length.

摘要： Apparatus in which the photographic images on a strip roll of silver halide film are duplicated upon a strip roll of electrophotographic film. The apparatus feeds the strips of the two rolls into contact with one another, emulsion side of the photographic film against the coating side of the electrophotographic film. At the projection station there is a projected light beam passing through the contacting films. A charging station is provided for charging the electrophotographic film just before it contacts the photographic film and a toning station and a fixing station respectively are located to act upon the electrophotographic film after exposure.Alternatively, the toned image may be transferred to a strip of clear base film from the coated surface of the electrophotographic film followed by fixing of the transferred image. The electrophotographic film then is reused while the clear base film becomes the duplicate of the original.The method involves the use of an electrophotographic film which will not lose charge by virtue of contact or by static electricity because of the separation of the films after contact. The electrophotographic film is coated with a very thin layer of insulating hydrocarbon before the contact occurs to prevent static discharge when the films separate and for other reasons.Background density of the original film is measured by photometric means and compared with preset density standards or used to adjust the sensitivity of the electrophotographic film through charging to provide optimum duplicated quality.

摘要： A system for impressing images on electrophotographic film provides apparatus for charging each film frame rapidly to a peak voltage determined by the prevailing light conditions of the image to be produced or recorded. After charging, means are provided for immediately exposing the frame to an image. In the preferred apparatus, means are provided for adjusting the time of exposure to a fixed period which is predetermined. Means are provided for applying toner to the exposed frame immediately after exposure in the presence of a bias field which propels the toner particles toward the film. Thereafter excess toner is removed from the film or leaves the frame and the remaining toner is fused to the surface of the film to form a permanent visible image on the film frame. An alternate form of the invention provides means for transferring the toned image to an acceptor member where it is fixed.The apparatus includes structure which enables the processes above described to be carried out along a line or in a rotary arrangement. Electronic and electrical circuitry are provided for accomplishing the various functions in proper sequence and timing.The apparatus is arranged to carry out the processes at points on the dark decay portion of the characteristic discharge curve for the particular film so that the resultant image has high resolution, optimum contrast and a substantially continuous gray scale. The quality is as good as if not better than photographic quality. The sensitivity of the film is controlled by the level to which it is charged and circuitry provided enables this to be automatically accomplished. The level in turn is chosen on the basis of the average light of the image or scene to be recorded and means are provided to accomplish this automatically or manually.

摘要： An electrophotographic film member is exposed to an image source, such as a cathode ray tube display unit, and the latent image toned to form a temporary visible image on said film member at a first station. The film member carrying the temporary visible image is stepwise translated to a projection station where it is projected in an enlarged display upon a suitable receptor surface. Thereafter, the film member is stepwise translated to an erase station where the toner is removed and the film member made ready for reuse to receive another image. The first station includes suitable structure for charging the film member, a selectively operable blind or shutter for exposing the charged film member to the image source and an applicator for applying suitable toner from a toner source to the exposed film member. The toner particles adhere tenaceously but removably to the exposed film member without any fixing or fusing process and hence, the toner can be removed from the film member afer projection. During charging and toning, the film member is maintained in darkness.The electrophotographic film member is mounted in a window formed in a disc arranged for stepwise rotary translation from station to station. The electrophotographic film member comprises a thin film coating of an inorganic, photoconductive, electronically anisotropic material, one example of which is a specially sputtered cadmium sulfide bonded to a thin film layer of ohmic material which in turn is bonded to a thin stable substrate member preferably formed of plastic sheeting. The total thickness of the photoconductive coating is about 3,000 Angstroms and the ohmic layer is about 500 Angstroms. The film is durable with a hard abrasive resistant surface, is highly transparent and has high photoelectric gain. Its speed and sensitivity are such that a projectable transparency is formed almost immediately to enable projection of the received image almost as soon as it is received from the image source. The speed of the stepwise translation preferably is sufficient to provide successive projectable transparencies to the projection station fast enough to fall within the image retention capabilities of the human eye, thereby effecting a cinematographiclike display.

摘要： A method of and apparatus for toning an exposed electrophotographic member in a camera or other electrostatic imaging device which uses liquid toner comprising toner particles suspended in a dispersant.The method contemplates running the liquid toner into a chamber containing the photoconductive surface of the electrophotographic member and a metal plate parallel with one another and spaced apart as two boundaries of the chamber. During the toning operation, a low d.c. bias is applied across the chamber between the photoconductive surface and the plate of a polarity opposite to that characterizing the latent image such as to repel toner particles from the photoconductive surface, but the voltage of the bias is low enough not to affect increments of the surface which have substantial charge on them. The result is that said increments with very little charge are left with practically no adhering particles. When the toning is completed, the bias is substantially increased to cause strong attraction to the plate so that any particles floating in the liquid toner which have not adhered to the photoconductive surface tend to collect on the plate. Since the other particles have adhered to the latent image on the photoconductive surface, the toner is cleared of floating particles and can be run out of the chamber leaving the toned image clean of particles in the untoned so called background areas.

摘要： Method and apparatus for coating a thin film upon substrate means in a pressure vessel using the plasma vapor deposition technique known as sputtering. The substrate means are arranged on the exterior of a cylindrical drum for rotation and have the convex surface thereof exposed to the plasma vapor during rotation. An assembly of a plurality of circumferentially spaced arcuate target segments forming generally a cylinder is arranged coaxially and telescopically with respect to the drum whereby to form an annular belt of plasma vapor cloud segments occupying the gap exterior of the drum between the target means and the drum. The target means comprise the cathode of the high voltage electrical circuit and the drum comprises the anode.The projecting unit target area is larger than the unit exposed substrate area enabling radially converging plasma vapor and hence high rates of uniform coating.The drum may rotate the substrate means in the belt repeatedly or serve as transport means to bring the substrate means through the belt on one pass. The cylindrical belt is not closed but has a discontinuance which is somewhat greater than the distance between target segments. The substrate means are led onto the drum from the exterior of the assembly of target segments and likewise led off the drum and conveyed to the exterior of the assembly of target segments by way of such discontinuance.
