  • Publication number: 20090226035
    Abstract: A three-dimensional-object can be effectively detected. A pair of image capture devices capture a three-dimensional-object and calculate disparity component data of subdivided-image regions, respectively. On a basis of the disparity component data, gray scale values indicative of distances from the image capture device are calculated and a gray scale image in which each region has its corresponding gray scale value is generated. A model of the three-dimensional-object is defined and correlation values is calculated to show the degree of a similarity between the model and the image subdivided regions in the gray scale image. The model is a two-dimensional image with a shaping characteristic when the three-dimensional object is viewed from positions of the image capture devices while each subdivided region of the two-dimensional image has a gray scale value indicative of a distance from the image capture device at a portion corresponding to the three-dimensional object.

  • Patent number: 7563580
    Abstract: A nucleic acid adsorbent in which a polymer having a constitutional unit represented by the following formula (I) is immobilized on a water-insoluble carrier is used as a nucleic acid adsorbent capable of selectively and efficiently adsorbing nucleic acids from complex mixtures, such as cell extract, wherein R1 represents hydrogen, fluoride, or methyl; R2 and R3 each independently represent alkyl of 1 to 6 carbon atoms; A is —NH— or —O—; and B represents alkylene of 2 to 18 carbon atoms. Nucleic acids are recovered from cell extract by allowing them to be adsorbed to the nucleic acid adsorbent by mixing this nucleic acid adsorbent with cell extract, removing the nucleic acids from the cell extract by separating the adsorbent therefrom, and dissociating the nucleic acids from the nucleic acid adsorbent by treating the separated nucleic acid adsorbent with alkali.

  • Publication number: 20090111122
    Abstract: It is found that blood cytochrome c levels quantified for non-alcoholic steatohepatitis patients are higher than those for healthy persons, and that the quantified blood cytochrome c values correlated with fat deposition rates in hepatocytes. It is possible to test non-alcoholic steatohepatitis by quantifying cytochrome c in serum. A test method and a test kit for the test are provided.

  • Publication number: 20090056837
    Abstract: The present invention provides a magnesium alloy material excellent in high mechanical characteristics without using special manufacturing facilities or processes and a method for manufacturing the magnesium alloy material. The magnesium alloy material is an Mg—Zn—RE alloy containing Zn as an essential component, at least one of Gd, Tb, and Tm as RE, and the rest including Mg and unavoidable impurities and contains a needle-like precipitate or a board-like precipitate (lengthy precipitate: X-phase=?-phase, ??-phase, and ?1-phase).

  • Publication number: 20080152532
    Abstract: The present invention provides a magnesium alloy material, having superior mechanical properties without using special production equipment or processes, and a production process thereof. The magnesium alloy material of the present invention composed of an Mg—Zn-RE alloy comprises essential components in the form of 0.5 to 3 atomic percent of Zn and 1 to 5 atomic percent of RE, with the remainder comprising Mg and unavoidable impurities. The Mg—Zn-RE alloy has a lamellar phase formed from a long period stacking ordered structure and ?-Mg in the alloy structure thereof. The long period stacking ordered structure has at least one of a curved portion and a bent portion and has a divided portion in at least a portion thereof. Finely granulated ?-Mg having a mean particle diameter of 2 ?m or less is formed in the divided portion.
