  • Patent number: 7182438
    Abstract: The electrostatic ink jet head includes a head substrate, a first drive electrode and a second drive electrode which are formed as a double-layer electrode structure for each of the individual electrode units, an ink guide and an insulating substrate in which a through-hole is formed at a position corresponding to the ink guide. In this electrostatic ink jet head, ejection/non-ejection of the ink is controlled according to a superposed voltage obtained by applying voltages of the same polarity to the first drive electrode and the second drive electrode according to image data.

  • Publication number: 20050161426
    Abstract: An image-recording apparatus and image-recording process capable of suppressing mispositioning of recording of an image from an ideal position while correcting for mispositioning of the recording of the image in a case in which a recording medium is deformed to an arbitrary shape. When a wiring pattern is to be recorded on a PWB (printed wiring board) using raster data, deformation information representing a state of deformation of the PWB is acquired beforehand. On the basis of this deformation information, the raster data is converted such that the wiring pattern that is recorded will, after the deformation, have the same shape as the wiring pattern represented by the unconverted raster data. On the basis of the converted raster data, the wiring pattern is recorded at the PWB before the deformation.

  • Patent number: 6908177
    Abstract: An electrostatic ejection type ink jet head according to an embodiment of the present invention includes: first drive electrodes that are respectively provided for individual electrodes and are arranged closer to an insulating substrate side than an ink flow path; and a second drive electrode that is provided commonly among all of the individual electrodes and is arranged closer to a head substrate side than the first drive electrodes. At the time of recording of an image, ink ejection/non-ejection is controlled by biasing the second drive electrode to a predetermined voltage level having the same polarity as a fine particle component contained in ink and switching the first drive electrodes between a high-impedance state and a ground level in accordance with image data.

  • Patent number: 6882357
    Abstract: An image is accurately recorded by a light beam on a PS plate wound on a drum which is rotating at a constant speed. A rotary encoder detects information of a recording position in a main scanning direction by the light beam that is emitted from an optical unit to the PS plate. Based on the detected information, a PLL circuit of a recording synchronizing signal generating unit generates an original clock. Pulses of the original clock are counted by a decimating counter, which outputs a decimating instruction to decimate a pulse from the original clock each time the count reaches a preset count. Based on the decimating instruction, a pulse is decimated from the original clock, and a decimated clock is frequency-divided at a fixed frequency-dividing ratio by a frequency divider, which outputs a pixel clock for recording the image.

  • Publication number: 20050036783
    Abstract: In a pattern production system, resist coated on copper foil on the substrate is exposed to light, by direct drawing, on the basis of a width of a line forming a pattern designated by processing pattern data at a predetermined exposure, the exposed resist is developed to form a resist pattern, and the copper foil is etched to form an etched pattern. An image of the etched pattern is scanned and image information of the etched pattern is obtained. The width of the line forming the pattern represented by the image information and the width of the line forming the pattern of the target etched pattern are compared, and the width of the line forming the pattern designated by the processing pattern data is adjusted on the basis of the result of comparison. The resist is exposed to light, by direct drawing, with the adjusted line width on the basis of the result of comparison.

  • Patent number: 6819346
    Abstract: An image recording apparatus records an image on a printing plate wound around a rotating drum with a light beam emitted from an exposure head. In the image recording apparatus, an actual drum rotational speed Nx is recognized, and the image is recorded on the printing plate in an accelerating period in which the actual drum rotational speed Nx is equal to or higher than a predetermined rotational speed, a constant-rotational-speed period, and a decelerating period. An exposure beam position, an exposure beam output, and an auxiliary scanning speed of the exposure head are corrected dependent on the peripheral speed of the drum in the accelerating period and the decelerating period.

  • Patent number: 6744491
    Abstract: For dividing an image and recording divided images on a photosensitive film with a plurality of laser beams, an auxiliary scanning speed is reduced in the vicinity of junctions between adjacent ones of the divided images to adjust the intervals between main scanning lines, and each of the main scanning lines is divided into divided main scanning lines in a main scanning direction, and the divided main scanning lines are formed separately in an auxiliary scanning direction. With such a correcting process, a high-quality image free of striped artifacts and inclination differences of main scanning lines can be recorded on the photosensitive film.

  • Patent number: 6144469
    Abstract: Corrective line quantities for compensating for differences between reading positions in an auxiliary scanning direction of linear image sensors of a 3-line image sensor are determined, and the determined corrective line quantities are divided into integer-part corrective line quantities and decimal-part corrective line quantities. The decimal-part corrective line quantities are interpolated in real-time by a hardware arrangement from preceding image data and presently read image data, using line buffer memories. The integer-part corrective line quantities are changed in addresses when they are stored as a file in a hard disk or the like, thus providing image data which are equalized in reading positions.

  • Patent number: 6034794
    Abstract: Light which bears image information carried by a subject is two-dimensionally read through tricolor separating optical systems with linear image sensors for the three colors R, G, B. Odd- and even-numbered pixel signals outputted from the linear image sensors 1 are alternately read to produce an image signal which comprises a series of pixel signals. The image signal is corrected successively by an offset level corrector, a sensitivity variation corrector, an auxiliary scanning curvature/odd- and even-numbered pixel level difference corrector, a main scanning aberration/magnification corrector, and a luminance-to-density conversion corrector, thereby producing an image signal for producing a high-quality reproduced image.
