Kazumasa Nishiwaki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9555607
    Abstract: A tape sticking apparatus includes a rubber sheet that partitions an airtight space formed above a chamber into first and second airtight spaces and, a tape frame that holds a tape above the rubber sheet, and a supply/exhaust mechanism that switches between pressurizing and depressurizing by supplying gas to or sucking gas from the first and second airtight spaces. The gas supply/exhaust mechanism includes a first flow-rate control valve that controls the flow rate of sucked gas when the first airtight space is depressurized, and a second flow-rate control valve that controls the flow rate of supplied when the first airtight space is pressurized.
    Type: Grant
    Filed: June 28, 2012

  • Publication number: 20090028419
    Abstract: A phosphor paste is applied to inner surfaces of a cell. Then, a conveyer moves a substrate relative to a CCD camera at a constant speed. Simultaneously, two LEDs radiate visible light onto a portion, to be inspected, of the substrate. The visible light is light configured to have a wavelength so as to be able to prevent the phosphor of the phosphor paste from being excited and emitting light and reflected by a liquid surface of the phosphor paste to produce reflected light. Thereafter, the CCD camera captures an image of the phosphor paste and a data processor processes the received image data, and determines whether a phosphor layer formed by drying the phosphor paste will normally be formed, prior to formation of phosphor layer.
