  • Publication number: 20190170755
    Abstract: The present invention provides a method for detecting circulating tumor cells, comprising steps of: capturing cells in a blood sample on a filter; contacting an antibody that is labeled with a first fluorescent dye and recognizes a leukocyte marker protein with the cell-captured filter; contacting an animal serum, a surfactant and an antibody that is labeled with a second fluorescent dye and recognizes an epithelial cell marker protein with the cell-captured filter; contacting a third fluorescent dye that stains nucleic acids with the cell-captured filter; and detecting fluorescences emitted from each cell captured on the filter.

  • Patent number: 10048335
    Abstract: A specially shaped coil assembly for accurate adjustment of the magic angle is provided to permit accurate adjustment of an angle made between the direction of a static magnetic field and the axis of sample spinning without impairing the resolution of NMR signals. The sample is placed within the external static magnetic field B0. The coil assembly is for use in a solid-state NMR apparatus that performs NMR detection while spinning the sample about an axis tilted at the magic angle relative to the external static magnetic field B0. The coil assembly comprises a pair of arcuate conductor lines and a pair of straight conductor lines. Each of the arcuate lines has a diameter of 2a. Each of the straight lines has a length of 2L. The diameter 2a and the length 2L are so selected as to satisfy the relationship: 1.91?2L/2a?2.15.

  • Patent number: 7663759
    Abstract: An image taken by an imaging device is displayed on a display unit. When a confirmation instruction is inputted through an input unit, image teaching is performed while the image displayed on the display unit is set to a setting object image. A measurement item which is of a candidate of a measurement process including specification of a reference position is displayed as the measurement process to accept selection. Specification of cutout area which constitutes one measurement target region is accepted, a measurement point including a local region or a feature point which is used for the measurement is automatically set in the measurement target region based on pieces of information on the set measurement process and reference position.

  • Patent number: 6839144
    Abstract: An optical displacement sensor takes in a plurality of images of a target object by projecting a slit beam of light and using a two-dimensional image taking element by changing the image taking conditions each time. Parameters defining these conditions affecting the brightness of the obtained image are varied. From each of these images including an image of a portion of the sectional contour line of the target object, a segmented image satisfying a specified maximum brightness condition is extracted and a synthesized image is generated by gathering such segmented images. The target object is inspected from such synthesized image.
