  • Patent number: 7283306
    Abstract: A confocal optical scanner of Nipkow disk type for measuring a sample, in which each component of two or more color pigments, has a high reflection mirror for separating an excited light to be radiated onto the sample and a fluorescence emitted from the sample, wherein a reflectance of the high reflection mirror is from 80% to 100% in a measured wavelength region including at least an excited light wavelength region and a fluorescence wavelength region. Thereby, the confocal optical scanner capable of measuring a polychromatic fluorescent image at the same time is realized with the enhanced light receiving efficiency of fluorescence, using one high reflection mirror without using a plurality of dichroic mirrors by exchange.

  • Patent number: 6828141
    Abstract: A method for purifying matter contaminated with a halogenated organic compound is disclosed. The method includes the step of adding a reducing agent and a nutritional source for a heterotrophic anaerobic microorganism to the contaminated matter. The reducing agent is reduced iron, cast iron, iron-silicon alloy and so on, or a water soluble compound. A combination of chemical reactions with microorganisms allows to decompose the halogenated organic compound. The nutritional source including an organic carbon and 20 to 50 percent by weight of an oxidized form of nitrogen is added, thereby preventing by products of the decomposition such as generation of noxious gases and decoloration of soil. A method includes the steps of mixing a reducing agent and a nutritional liquid with the contaminated matter, wherein the mixing step including a step of adjusting the contaminated matter at pH ranging from 4.5 to 9.

  • Patent number: 4319489
    Abstract: An ultrasonic diagnostic method and apparatus are provided for probing the condition in a tissue of a living body by projecting an ultrasonic beam onto the living body from a vibrator array transducer probe consisting of a plurality of tiny ultrasonic vibrators. The apparatus executes two scanning actions, of which one is a normal linear scanning that drives the ultrasonic vibrators sequentially in the manner to cause a sequential parallel shift of the ultrasonic beam substantially perpendicular to the vibrator array, and the other of which is an inclined linear scanning that drives the ultrasonic vibrators at individually different timings while sequentially shifting the driven vibrators in the manner to cause sequential parallel shift of the ultrasonic beam having an angle of inclination against the vibrator array. The images obtained through the normal linear scanning and the inclined linear scanning are combined to form a composite high-resolution image.
