  • Patent number: 6245249
    Abstract: A substrate on which a plurality of thin films having a plurality of cross-sections corresponding to the cross-section of a micro-structure are formed is placed on a substrate holder. The substrate holder is elevated to bond a thin film formed on the substrate to the surface of a stage, and by lowering the substrate holder, the thin film is separated from the substrate and transferred to the stage side. The transfer process is repeated to laminate a plurality of thin films on the stage and to form the micro-structure. Accordingly, there are provided a micro-structure having high dimensional precision, especially high resolution in the lamination direction, which can be manufactured from a metal or an insulator such as ceramics and can be manufactured in the combined form of structural elements together, and a manufacturing method and an apparatus thereof.

  • Patent number: 6246850
    Abstract: A light source within a photocopy machine continuously shines high level, wide band fluorescent light on the photoreceptor to maintain the photoreceptor in a uniformly light-shocked condition. This constant level of light shock has no adverse effects on either the life or performance of the photoreceptor in normal operation. Thus, the photoreceptor becomes less sensitive to unintentional, uneven ambient room light and random, long lasting delta voltages within the print area are reduced so that print quality defects are minimized.

  • Patent number: 6245402
    Abstract: An intermediate transfer belt with a mechanically and electrically invisible seam formed by joining two ends of the belt at a seam. Two regions of the belt are thus formed, a seam region at and around the seam and a far region away from the seam. An overcoat is then placed over the seamed substrate such that an outer surface of the overcoat forms a toner-bearing surface. The seam region has good electrical property correspondence (as explained in the patent) with the far region and a lateral resistivity greater than 108 ohms/square. The joining of the belt can occur along a kerf.

  • Patent number: 6246419
    Abstract: A method and apparatus for overloading operators in Page Description Language (PDL) defined graphics adjusts widths of lines in a manner that yields preferred line widths, such as to compensate for certain undesirable line growth characteristics of a target printer or display device. Line width can be controlled based on various attributes, such as color, size, width, pattern or orientation. Line width can be redefined to be wider, narrower or of a differing color to achieve a desired printed graphic. The method, performed within a decomposer, examines individual lines of a PDL defined graphic, determines if compensation is needed to achieve a desired printed output, and redefines a modification attribute to achieve the compensation.

  • Patent number: 6246781
    Abstract: A system and method which enables the location and orientation of an image to be determined without introducing scanning artifacts into the rendered image. The system utilizes a separate set of sensors on a scanning bar that are sensitive to a wavelength of light outside the range of wavelengths of the typical sensors found on the scanning bar, such as red, green, or blue. Moreover, the system includes a light source which is capable of emitting the wavelength of light that is outside this range of wavelength of light. Thus, whenever the additional set of sensors detect light, the system would determine that the light was due to a scanning artifact, such as a hole, rip, or dog ear in the original document being scanned.

  • Patent number: 6245475
    Abstract: A method of forming one or more polymer containing layers on a substrate using ink jet nozzles. The method is particularly suited to forming one or more polymer containing layers of a photoreceptor. The polymer containing layers may be formed by moving a substrate, in particular a cylindrical substrate, past the ink jet nozzles, by moving the ink jet nozzles over the substrate, or both. The ink jet nozzles are capable of being independently controlled in order to permit precise location of the coating on the substrate.

  • Patent number: 6243662
    Abstract: Information consisting of a plurality of pieces of data can be reproduced in the same state it was browsed previously. On receiving a data acquisition request from a data use unit, a request analysis unit analyzes whether the data acquisition request is a data relay request or a history information acquisition request. As a result of the analysis, if the data acquisition request is a history information acquisition request, the request analysis unit extracts a data name, time, and a search method from the data acquisition request. If the data acquisition request is a history information acquisition request, a history management unit uses a data name and time extracted by the request analysis unit to search a history memory for appropriate history information by a search method extracted by the request analysis unit and outputs data contained in the detected history information.

  • Patent number: 6241245
    Abstract: Apparatus for transporting sheets in a longitudinal direction includes an improvement for reducing the imparting to the sheet material of friction, static charge, and foreign deleterious material while substantially minimizing the burnishing of the surface of the sheets. To this end, a plurality of elongated sheet supporting rib members project outwardly from a guide surface, extend diagonally relative to the longitudinal direction, are all of uniform height above the sheet guide surface, and are of uniform cross section. The sheet supporting rib members are so dimensioned and positioned that any random element of a sheet being fed in the longitudinal direction through the apparatus crosses only one of the sheet supporting rib members. Actually, a plurality of first sheet supporting rib members extend diagonally in a first direction and another plurality of elongated second sheet supporting rib members extend diagonally in a second direction which is transverse of the first direction.

  • Patent number: 6243740
    Abstract: The present invention provides a method and system of publicly co-creating a narrative document by parallel and on-going communication of a plurality of signals comprising public reactions to portions of the document, the signals being generated via one or more repurposed signaling devices. A display illustrates an introductory portion of the document intended to engender a public interest in the document and an emotive or intellectual reaction thereto. The document can comprise a dependent set of associated document elements which are sequentially variable for variation of document content to evolve different document narratives. The public viewing the display communicates, via the device or devices, a signal indicative of their reactions and for effecting a prospective scene selection in the document content that, in turn will vary the narrative.
