  • Apparatus for controlling the degree of paper fiber variation
    Patent number: 5622602
    Abstract: An apparatus for controlling the degree of fiber variations in paper sheet has a formation meter for receiving an image of transmitted light on one side of an area of paper from a light source located on the other side of the area of paper, an image processing computing element for introducing the image from said formation meter for image processing and a fuzzy control unit for calculating and outputting optimum J/W ratio, optimum foil angle, and optimum deflector pushing degree and angle on the basis of results of image processing from said image processing computing element.

  • Method for measuring and controlling fiber variations in paper sheet
    Patent number: 5393378
    Abstract: A formation control method and apparatus in which an image is emitted from a light source and transmitted through a predetermined area of paper an captured by a camera to be displayed as transmitted light image on a display of an image processing computing element, the transmitted light image displayed on the display being image-analyzed to obtain formation factor for quantification of the formation, J/W ratio and the like being optimized by fuzzy control using membership functions based on said formation factor so as to improve the formation.

  • Cancer therapy system
    Patent number: 5243612
    Abstract: In a solid-state laser, a YAG laser generates laser beam with a predetermined wavelength in response to which a titanium-sapphire laser is pumped to generate laser beam with a predetermined wavelength which is administered through a fiberscope to irradiate focuses, treating or destroying the same.

  • Liquid leakage detection system
    Patent number: 4270049
    Abstract: Leakage of a liquid may be detected in terms of the drop in intensity of light rays traveling through a light guide core or optical fiber made of glass or synthetic resins due to the adhesion of the leaked liquid to the light guide.
