  • Publication number: 20050255472
    Abstract: A novel method for analyzing a specimen molecule with high accuracy through a simple operation by forming a laminar flow of a specimen molecule containing solution and a complex forming molecule containing solution in a microchannel and measuring the variation of the degree of diffusion of complexes each composed of a specimen molecule and a complex forming molecule in the laminar flow. The complex forming molecule is fluorescent, and the variation of the degree of diffusion of the formed complexes is measured from the distribution of intensity of fluorescence. The degree of diffusion of the formed complexes can be quantitatively determined by comparing it with a calibration curve preliminarily defined.

  • Patent number: 6824447
    Abstract: The method forms a transparent polishing pad by first step forming a plurality of openings through a disk-shaped pad body. The plurality of openings is distributed about the disk-shaped pad body and a transparent window within a portion of the pad body and the transparent window. Then sealing the openings in the transparent window with a transparent material allows transport of polishing fluids through the openings in the disk-shaped pad body and prevents transport of the polishing fluids through the transparent window.

  • Patent number: 6786412
    Abstract: Coordinate positions of four points are detected from a captured two-dimensional code image. The two-dimensional code size and coefficients of equations are determined for coordinate positions corresponding to center positions of respective cells compensated for inclination of the image by adding depth information. The coordinate positions of respective cell center positions are determined according to the calculation equations by applying the determined coefficients. Brightness/darkness is discriminated from image data corresponding to the respective cell center positions and binary data (0 or 1) for respective cells are generated. Two-dimensional code information is reproduced based on the binary data. The equations are expressed by recurrence formulas. The coefficients determined from the coordinate positions are divided by the same constant to make them integers.

  • Patent number: 6700559
    Abstract: Eight-bit digital image data of R, G and B output from an image data memory are corrected by conversion controllers to meet characteristics of a liquid crystal panel. The corrected data are input to a liquid crystal drive circuit as digital image data, and an image is displayed on the liquid crystal panel. A LUT stored in a LUT reference processor stores data (addresses) by a number that makes it possible to refer to input image digital data at one to one. A random number generator is for generating random numbers and supplying the random numbers to a round-to-integer processor as threshold value data. The round-to-integer processor compares the data referred to by the LUT reference processor with the threshold data, and carries out a round-to-integer processing.
