  • Patent number: 6836568
    Abstract: An object of the present invention is to provide an image processing apparatus which allows a user to execute image processing, such as extraction and elimination of a portion common to a plurality of images therefrom, with a simple operation. An image of a document is read by a scanner, and when the document is a first one, the image of the document is stored from input means into storing means. When an image of a second document is read, comparing means compares the read image with the image stored in the storing means to judge whether or not a difference in pixel values between the first document image and the second document image is smaller than a threshold value set through setting means.

  • Patent number: 6836269
    Abstract: A precharge control circuit constituted by (1) a latch circuit mounted in a precharge circuit and (2) a level shifter circuit of a current drive type controlled through an output of the latch circuit is included. The precharge control circuit changes the latch circuit to an active state to cause the level shifter circuit of a current drive type to operate only during a precharge period and also during immediately preceding and succeeding periods, and outside these periods, changes the latch circuit in a non-active state and the level shifter circuit of a current drive type in an operating state to save power consumption in the level shifter circuit. This enables a low-power-consuming precharge circuit, as well as a low-power-consuming image display device with a high quality display capability, to be offered.

  • Patent number: 6825849
    Abstract: In an information presentation apparatus, a documents parser reads out and analyzes desired document data from a documents storage unit to obtain attributes data of the document data, which is stored in a document attributes storage uni. A displaying attributes setting unit uses the document attribute information, or attributes data, stored in the document attributes storage unit to retrieve data from tables of document attributes and displaying attributes, and, based on the retrieval result, sets a displaying attribute for the relevant document data. A displaying data generator determines a displaying manner of the document data according to the displaying attribute thus set, and the document data is displayed on a displaying unit in the determined manner. Accordingly, a user can quickly estimate a document attribute suggested by the content of the document data, not by reading the document data, but only at a glance of the manner in which the document data is being displayed.

  • Patent number: 6824861
    Abstract: A composite-based rim and methods for manufacturing such a rim are provided. The rim includes multiple fiber-based, co-mingled layers, wherein the strength and/or stiffness of the layers increases from the innermost layer of the rim to the outermost layer of the rim, but where the radial stress and strain generated in the rim decreases from the innermost layer to the outermost layer. Incorporation of this rim into a high stress and strain usage environment, such as a flywheel system, allows the rim to be spun at high speeds in order to generate high levels of kinetic energy while beneficially managing the amount of strain and radial stresses generated within the rim, and, in turn, minimizing or at least controlling the formation and propagation of cracks within the rim.

  • Patent number: 6822630
    Abstract: A liquid crystal display device is arranged so that an effective value of an OFF voltage and an effective value of an ON voltage applied to a liquid crystal layer at a whole screen display time and at a partial screen display time substantially coincide with each other. More specifically, a bias ratio (a′) at a partial screen display time is set not higher than an optimal bias value, and a maximum amplitude value of an applied voltage waveform (driving voltage) at the partial screen display time (driving voltage=a′V0′) is smaller than that at the whole screen display time (driving voltage=aV0). By so doing, a pulse-like voltage load applied to liquid crystal molecules during ON time is reduced, and a display defect level during ON time can be improved to a level equal to or above that at the whole screen display level.

  • Patent number: 6822799
    Abstract: An exposing apparatus for a microlens array allows for easy alignment and attains high accuracy. An exposing method for a microlens array attains high accuracy and high light efficiency. The exposing apparatus for a microlens array includes a micro fly-eye lens for converting a light beam from a light source into a secondary point light source, a transmittance distribution mask for adjusting the luminance of the light of the secondary point light source, and a collimator lens for converting the light of adjusted luminance into a parallel light beam and for guiding the parallel light beam, via a first microlens array which is formed in advance, to a photosensitive resin layer to be a second microlens array. The light emitted from the light source is transmitted through the micro fly-eye lens, the transmittance distribution mask, and the collimator lens. The light is then adjusted to a desired luminance to expose the photosensitive resin of a microlens substrate.

  • Patent number: 6822752
    Abstract: In a copier, a specific pattern being hardly recognizable by human eyes but recognizable by a recognizing means is added onto a color image to be printed on a recording medium in order to clearly indicate that the printed image is a copy image. RGB-color image data is converted by a post processing portion of an image processing unit into YMCK color image data. An additional color forming unit calculates color data YaMaCaKa of a specific pattern received from a specific pattern generating unit based on the RGB-color image data. A combining unit generates output Y′M′C′K′-color image data including the specific pattern color image data by combining YMCK color data with the specific pattern data of YaMaCaKa. An image output unit adds the specific pattern on the color image according to the Y′M′C′K′ color image data.

  • Patent number: 6822209
    Abstract: The focal point detection method detects focal point dislocation of a coupling objective lens in accordance with a light beam passing a 60% to 80% region of a light beam effective diameter, which is centered with respect to an optical axis OZ of a light beam passing through the coupling objective lens, and which is regulated by a numerical aperture of the coupling objective lens. In this manner, focal point dislocation of a converging optical system can be performed without an offset, thereby accurately forming a focal point of the converging optical system on an information recording layer of an optical recording medium.

  • Patent number: 6817266
    Abstract: Several embodiments of a stiff, metallic hub for an energy storage devices are disclosed in the present invention. The stiff hub produces a critical velocity that is significantly greater than the design operating speed of the flywheel assembly so that resonant frequency is never reached during normal operation of the energy storage device's flywheel assembly. The stiff hub comprises a central core section that maintains a tight interference fit with the rotating shaft; an outer rim section that maintains a tight interference with the high-strength, low-density composite fiber rim, in which energy primarily is stored; and a web section that is situated therebetween, extending radially from the rotary shaft. At high operating speeds, the outer rim of the hub expands radially commensurate with expansion of the composite fiber rim so that enough of the outer rim remains in tight interference fit with the composite fiber rim to substantially minimize vibrations.
