  • Patent number: 6293541
    Abstract: Featured is a sheet feed unit including a first transport path in which is transported a first sheet, a second transport path and a protrusion. A second sheet is transported in the second transport path and guided at a prescribed angle relative to the first transport path. The protrusion is located or fixed at a confluence of the first transport path and the second transport path. The protrusion also has a guide surface that is placed to allow the second sheet to be guided along the first transport path.

  • Patent number: 6290358
    Abstract: A polarized-light converting elemental device which can produce an accurately unidirectionally and circularly polarized light with a minimized loss of light and a projection-type display device using said unidirectionally-polarized-light converting elemental device are provided. A polarized-light converting elemental device comprises a mirror glass portion consisting of an array of mirror glass blocks each having a first reflecting optical element and a second reflecting optical element and a cholesteric-liquid-crystal glass portion including a cholesteric liquid crystal layer for reflecting either clockwise circularly polarized component or anticlockwise circularly polarized component and transmitting the other.

  • Patent number: 6272261
    Abstract: The present invention provides an image processing device capable of performing high-resolution conversion, enlargement processing, etc. which, even with images including both text images and photographic images, satisfies both sharpness of text areas and smoothness of photograph areas. The image processing device according to the present invention performs frequency conversion, using a frequency conversion device, of partial images which are the objects of processing, resulting in a matrix of frequency-converted coefficients; divides into a plurality of domains, using a plurality of patterns, the matrix of frequency-converted coefficients; and quantifies each such domain by finding a mean value of the coefficients of that domain as a feature quantity for that domain.

  • Patent number: 6262505
    Abstract: A power supply device for providing uninterrupted power for a period of time is disclosed. The power supply device has a controller and a flywheel device. The flywheel device has a housing that contains a flywheel rotor and a motor/generator rotor. The flywheel rotor and the motor/generator rotor are mounted on a common shaft. An active axial magnetic bearing is located to support the shaft for frictionless rotation. The bearing provides support for the shaft, the flywheel rotor and motor/generator rotor. The axial magnetic bearing is attached to the housing and provides, in combination with the motor/generator rotor, a flux path and magnetic field to exert a magnetic force to lift the motor/generator rotor and the shaft on which it is mounted.

  • Patent number: 6239855
    Abstract: A method for producing a liquid crystal display panel of the present invention includes the steps of: forming a plurality of injection seals on at least one of a pair of substrates, the injection seals defining a liquid crystal injection area; forming a dummy seal of dispersed sealant particles outside the liquid crystal injection area; attaching the substrates to each other thereby sandwiching the injection seal and the dummy seal therebetween; and injecting a liquid crystal material into the liquid crystal injection area formed between the pair of substrates.
