Abstract: An x-ray photoreceptor for use in a xerographic system having a high arsenic layer 5 to 40 microns in thickness between the substrate and the selenium layer for trapping positive charge injected from the interface. Since this positive charge otherwise tends to discharge a negatively charged plate, the provision of this trapping layer will allow the plate to be used for either positive or negative charging.

Abstract: Asynchronous high-speed film transport apparatus wherein supply and take-up reels have opposite ends of an elongated film wound thereupon. A pair of drive motors one for each reel is selectively operable to rotate the reels respectively to move film along a path from one reel to the other. First and second film vacuum chambers are associated respectively with the supply and take-up reels, each chamber being arranged to hold a loop of film, the chambers being positioned adjacent the film path between the reels. Means are connected to the drive motors for producing movement of the film and sensing means are provided for maintaining a predetermined loop of film in each of the chambers during film movement. Between the first vacuum chamber and a read/record station is a first clamp for the film and a storage device for controlling the film advance, the storage device including a movable member for controlling the length of a frame. A second film clamp is positioned opposite the read/record station. Before frame advance, the second film clamp is closed and the first clamp is opened. Film is then pulled from the film loop formed in the supply reel vacuum chamber by applying air pressure and/or vacuum to the film in the storage device. At the same time, the movable member in the storage device, or film advance cavity, is positioned to provide the desired film advance distance. During film advance, the first clamp is closed and the second clamp is opened. Film is then pulled from the film advance cavity into the take-up free film loop by vacuum in the take-up film loop cavity and/or applied pressure.

Abstract: In a xerographic image, where a darker area is separated by a lighter area across a sharp boundary, there is an edge enhancement effect where there will be a black outline around the darker area and a white outline around the lighter area. In x-ray mammography, the effect is that the skin line will be darkened for a positive image and lightened for a negative image, and a loss of detail at the skin line will result. To increase visible detail at the skin line without increasing the radiation, a recharging scorotron can be used between the imaging and toner stations to recharge back to a low level of charge only those areas of the latent image that have been fully discharged. All other areas are allowed to remain unchanged. The result is a reduction of skin line deletions at a reduced x-ray exposure. Such a scorotron, in the shape of a box around the corona wires, can be constructed using a conductive top, insulative sides and a screen bottom. The top is held at approximately 200 volts, and the screen, made of fine wire, closely spaced, is held at about 40 volts. The distance from screen to photoreceptor is about 0.06 inches.

Abstract: A selenium alloy electrophotographic imaging member having an optically transparent NESA coated substrate. An x-ray image is formed from the side of the photoreceptor opposite the transparent substrate and then is scanned from the back side through the transparent substrate with a fine beam of light, the position of which is precisely monitored. The ensuing discharge from the light beam is detected by a non-contacting x-ray transparent electrode located on the outer side of the photoreceptor, away from the substrate, which reads the discharge signal through capacitive coupling, pixel by pixel, according to the position of the light beam, to form a high resolution raster pattern digital readout of the image.

Abstract: A process modification for the development of x-ray electrophotographic images with selenium photoreceptors wherein the occurrence of a catastrophic spot producing artifact called fatigue is eliminated. The process change consists of the addition of a photoreceptor pre-charging step immediately after thermal relaxation and before insertion of the photoreceptor in the elevator where it may be subsequently discharged by a suitable light source within thirty seconds of the pre-charging step. The effectiveness of the pre-charging step is achieved through field assisted detrapping of interference defect site injected holes which would otherwise detrap in the image charging step, thereby producing the fatigue artifact.
