  • Publication number: 20040026803
    Abstract: A process for producing a polymer optical waveguide, including the steps of: preparing a mold comprising a concave portion for forming a core; bringing a cladding film substrate, having good adhesiveness to the mold, into close contact with the mold; rotating the mold with which the cladding film substrate is brought into close contact and with one end of which an ultraviolet ray-curable resin or a thermosetting resin to serve as a core is brought into contact, so that a centrifugal force acts in a direction to move the ultraviolet ray-curable resin or the thermosetting resin into the mold, to fill the concave portion of the mold with the ultraviolet ray-curable resin or the thermosetting resin; and curing the ultraviolet ray-curable resin or the thermosetting resin.

  • Publication number: 20040027614
    Abstract: In a system, such as in a digital copier, for classifying image data derived from an original image, the image data is enhanced before submission to a classification analysis. In the enhancement, portions of the image having a measured roughness (degree of gray level discontinuity) within a certain range are artificially increased in roughness. This increased roughness in the enhanced image data serves to increase confidence of the classification analysis for detecting low-frequency halftone screens, so that such low-frequency halftone areas are not misclassified as contone or high-frequency halftone areas.

  • Publication number: 20040031042
    Abstract: Software in a computer which accesses one or more software-intensive devices, such as a digital copier or printer, is organized in a set of layers. A device-dependent layer converts data transferred over various means, such as a modem or network, to a uniform data format. A protocol layer converts data from a particular accessed machine to a set of function calls. A system interface associated with the computer restricts a user of the computer to seeing only a subset of function calls, depending permissions granted to a particular user. The modular architecture of the software enables a system administrator to restrict a user to viewing machine status for a specific set of machines on a network, or limits the user to viewing only a certain set of functionalities from a particular machine.

  • Publication number: 20040026010
    Abstract: A method of manufacturing on a continuous basis quantities of seamed belts with imageable seams for printing systems from a continuous supply web of belt material, which seamed belts need to be manufactured to a desired circumference and width. In the disclosed embodiment the sides of the incoming supply web are cut in seam-forming mating edges and the web is fed in at an angle to a pair of rollers, at least one of which is tapered, to spirally wrap the web into a cylinder of the desired circumference of the seamed belts and providing mating engagement and gluing of the seam-forming edges. Then by sequentially transversely cutting off cylindrical segments of that spirally formed cylinder into the desired width, multiple seamed belts are formed with both the desired circumference and width.

  • Publication number: 20040027607
    Abstract: When a communication control section of an image forming apparatus receives image information, an administration information acquiring section detects administration information from GPS information or the like received through an antenna. An administration information generating section generates the detected administration information in the form of an image. An administration information adding section adds the image indicating the administration information to the image information. An image forming section forms an image added with the administration information.

  • Patent number: 6690366
    Abstract: There is provided a display apparatus utilizing a display unit having memory properties, which notifies a user of the facts that the batteries have become low, that the batteries have been removed, that a normal voltage has been recovered as a result of reloading of batteries and the like. A display unit has memory properties and displays images under control of a display control unit. A power supply unit may be constituted by, for example, batteries and supplies power to each part of the apparatus. The power supply unit transmits a voltage drop signal to a central processing unit when the voltage of the batteries falls below a predetermined voltage. Upon receipt of the voltage drop signal, the central processing unit causes a part or the whole of a display area of the display unit to display the fact that the batteries are dead. It performs control to prevent a display from being changed even if an operating unit is operated or display information is received thereafter.

  • Patent number: 6690471
    Abstract: An improved and lower cost color spectrophotometer, especially suitable for on-line color printer color control systems, incorporating a low cost commercial imaging chip, which normally only forms part of a three row, three color, document imaging bar used for imaging documents in scanners, digital copiers, or multifunction products, having multiple photo-sites with at least three different color filters in three rows. This multiple photo-sites chip may be modified to also provide unfiltered photo-sites. This spectrophotometer may have a substantially reduced number of different LED or other spectral illumination sources, one of which may be for white light, yet provide multiple spectral data outputs from the differently filtered photo-sites being simultaneous illuminated by the light reflected from a color test target area which is being sequentially illuminated by the respective limited number of LEDs, enabling broad spectrum information and color control.
