Abstract: The present invention is an ink jet printer utilized to enlarge color images. Signals from a scanned image are converted by a color correction computer into control signals representing the density of the individual pixels of that scanned image. The color density signals are used to control the application of ink from ink jet spray nozzles located on a pair of printheads. Thus, the ink jet printer of the present invention reproduces the image on both sides of a translucent substrate to enhance the quality of the viewed image. The present invention is further provided with dual air sources to apply the ink. A first air source is pulse width modulated to control the amount of ink sprayed onto the substrate. A second air pressure source is continuously applied to the ink jet spray nozzles to remove the excess ink that accumulates about the nozzles during print operations.

Abstract: Holes are drilled in the flexure regions of a parallel beam load cell (14), the flexure regions defined by two cut-out portions (26 and 28) which extend between the longitudinal side surfaces (36 and 38) of the load cell (14). The holes extend inwardly of the load cell in the longitudinal side surfaces thereof. The location and depth of the holes are dependent upon the moment balance correction necessary.

Abstract: A magnetic recording medium having a triple layered structure including a substrate, a first layer or a soft magnetic thin film of high permeability piled on the substrate, a second layer or a vertical magnetization film piled on the first layer, a third layer or a soft magnetic film of high permeability piled on the second layer. A magnetic recording apparatus alternately switches the magnetization orientations of the second layer or the vertical magnetization film at a recording location where a latent image is to be formed. The first and third layer or the soft magnetic thin films can improve recording efficiency. The field produced by the second layer or the vertical magnetization film causes the third layer or the soft magnetic thin film to be magnetized along the surface of the magnetic recording medium, and this results in the concentration of the flux owing to switching of the magnetization directions. This enables high density recording and improves recording sensitivity and reproducing sensitivity.

Abstract: Multiple part documents in which each part has common non-variable information and variable information are produced at high speed with a minimum amount of equipment. Utilizing either sequential press technology or large diameter plates, the multiple parts of the document are sequentially printed on a single web with the non-variable information. The variable information is sequentially printed on the same web in a procedure distinct from the printing of the non-variable information, typically utilizing a single ion deposition printer for each face of the web. The parts are separated and intelligently gathered and then the parts are sealed together to form a document, along one edge, by applying glue, or pressure seal adhesive. After sealing the documents may be rotated and delivered to a carrier web. Alternatively, an outer wrapper or envelope, variably imaged by another ion deposition print engine, may be provided around the multiple part documents after sealing.

Abstract: The present invention concerns a process and a device for carrying out the process for weight determination of the contents of containers (5), for example for garbage. Two swivel arms (2) that are lifted by hydraulic devices (3) are mounted on a garbage collecting vehicle (1). The container (5) is carried by a fork (4). Integrated into the swivel arm (2) is a force measuring apparatus that comprises two flexural members (7) supporting the main load, two spring tongues (8), and a force transducer (11) that is installed between two stilts (12) between the spring tongues (8). The flexural members (7) and the spring tongues together form an elastic stepdown; the force transducer (11) thus only measures that part of the total load flowing through it as given by the stepdown. Further, a gradient meter (16) is mounted on the swivel arm (2), that has the same action line W as the force measurement device integrated in the swivel arm (2).

Abstract: An electronic printing apparatus employs a digitally controlled toner conveyor and large scale integrated circuits (ICs) controlling write electrodes to print monocomponent toners on plain paper in a single pass. The ICs convert high level image information into toner controlling pulses. Pixel intensity is programmed by associating a counted number of packets of toner with each level of pixel depth.

Abstract: An outer peripheral length of an intermediate transfer drum of a color laser beam printer is constituted in which a number of a beam detection signal obtained by one rotation of the transfer drum is formed as an integral number of a face number of a polygon mirror. A passing-through detection means detects the passing-through of a specified position mark on a photosensitive body belt and is provided on the photosensitive body drum at predetermined position. An image data requirement signal generating means controls a generating timing of an image data requirement signal for forming a toner image by the passing-through detection signal. A scanning line at a raster direction based on the beam detection signal after the transfer drum has rotated at one rotation returns and overlapped on a scanning line position formed on the first beam detection signal as a standard. A plural toner images having a different color each are formed on the transfer drum without color offset.

Abstract: A hydraulic by-pass control system is provided in the hydraulically operated lift assembly of a loader which uses double-acting hydraulic cylinders. The by-pass control system provides a low-resistance alternative pathway between the lowering circuit of the lift assembly and the hydraulic fluid tank. Accurate weighing measurement of the load on the lifting arms of the loader may be achieved by temporarily opening the alternative low-resistance pathway, thereby effectively converting the hydraulic circuit to a single-acting configuration during the taking of load cell signal measurements of back-pressure in the lift circuit.

Abstract: A single pass tandem color printer is disclosed which utilizes a plurality of Raster Output Scan (ROS) systems mounted within a common housing. The ROS systems produce a plurality of scanning beams which emerge from the housing along parallel paths. Each scanning beam is incident on the surface of an associated photoreceptor drum at a non-normal angle of incidence greater than zero to eliminate the reflections back along the optical path which may be present in conventional tandem scanning systems.

Abstract: The present invention is directed to a precise method of registering plurality of imaging stations, so as to form sequential images on a photoreceptor belt in a single pass. A belt hole is formed in the photoreceptor belt, outside the image area, but within the scan of the imager scan line. The scan line is sequentially swept in a transverse direction across the width of the belt. As the leading edge of the belt hole advances into the sweeping beam, a plurality of beam sweeps will occur while the leading edge is moving through the sweep area. Due to the gaussian illumination of the scanning beam, the exposure at the belt edge gradually increases to a maximum point coinciding with the maximum illumination of the scanning beam. A detector is placed beneath the belt to provide a signal representing the exposure level of each scanning beam which crosses the leading edge of the advancing belt hole. The detectors produce a current output representative of the exposure level.

Abstract: An electrographic printhead is operated to focus charged particles on a print member. In one embodiment successive electrodes are maintained at potentials that define increasing electric field strengths in the successive regions along the particle trajectory. In another embodiment, a thick electrode face defines equipotential lines that shape a sharply focusing electrostatic field that penetrates the projection apertures of the printhead. Improved focusing diminishes charge spreading effects, and allows effective positioning of the printhead at greater spacings to reduce the risk of arcing without loss of print resolution.
