Abstract: A photographic film printer that forms an image on film based upon received or stored digital information is provided. While maintained in a stationary position, the film is exposed in a sequence of raster scans by a rotating disk traversing the photographic film surface. At least one optical film is attached to the rotating disk in a manner that transmits optical energy directed towards the center of the disk to a peripheral location on the disk. Exposure of the film occurs by controlling the emission of optical energy by the fiber in accordance with the received or stored digital information as the peripheral edge of the disk rotates past the film surface.

Abstract: A photosensor (20a) has a pair of n-type semiconductor layers (21U, 21D) formed on the major surface of a p-type semiconductor substrate (31). A light-shielding pattern (24) comprised of unit light-shielding layers (33) is formed on the major surface of the substrate. When the major surface is scanned by a light beam in the direction (D X ) in which the unit light-shielding layers are aligned, a couple of photo-conversion signals indicating a current position of the light beam on the photosensor are generated in the photosensor. Since the light-shielding pattern is directly provided on the sensor body, no grating glass is required other than the photosensor.

Abstract: Apparatus for reading out individual x-ray images recorded on a double-emulsion radiographic film or on separate films that were coincident when exposed simultaneously to a polyenergetic or broad x-ray photon energy spectrum beam emergent from a body and where an image corresponding to one obtained with a low energy part of the spectrum is formed on one film and an Image corresponding to a higher energy part of the spectrum is formed on the other. One readout apparatus ia for the case of two separate films which, after development, are illuminated from the back and optically scanned to derive analog signals representative of the intensities of spatially corresponding picture elements on each film. Another apparatus is for the case where the two images are on opposite sides of a film and are represented by alternate fine image information lines obtained by interposing a grid during the x-ray exposure. Another is for the case where a reflective layer is disposed between the film images during readout. In all cases the films are optically scanned and the resulting analog signals are digitized and variously processed to yield an image representative of that which is different between the two original different energy images.

Abstract: A picture information input apparatus has a leading and trailing end detecting circuit (42) for detecting the leading and trailing ends of a document to produce read out signals of "1" and "0". The leading and trailing end detecting circuit (42) starts a first count by a document presence detecting signal of "0" from a detecting unit (54) which detects the transfer of the document. When a hole of the document is smaller than an allowable hole diameter, it clears the counting. Only when the hole is larger than the allowable hole diameter, it starts a second count. After the second count ends, it produces a read out signal of "0" indicating that the trailing edge of the document is detected. A picture bus control circuit (44) receives the read out signal of "1" to transmit a picture data signal to a picture transceiver (48), and receives the read out signal of "0" to stop the transmission of the picture data signal.

Abstract: A cylindrical engraving system selectively able to engrave either in a helical or circumferential format. An encoder scans index markings on the surface of a cylinder being engraved and generates timing pulses for selective application to one or the other of a helical drive unit or a circumferential drive unit incorporated within the system controller, Engraving is performed by an engraving head which is stepped in the axial direction along the workpiece in response to step pulses generated by the selected drive unit. The step pulses may be generated in spaced bursts or at a regular frequency depending upon whether circumferential or helical driving has been selected.
