  • Patent number: 9916658
    Abstract: An image acquisition unit (2020) acquires an analysis image. The analysis image is an image in which a plurality of cell nuclei in a lesion of a target person are captured. A feature-value calculation unit (2040) calculates the feature-value relating to the cell nuclei from the analysis image. An evaluation function acquisition unit (2060) acquires an evaluation function from an evaluation function storage unit (10). The evaluation function is a function with which prediction information is calculated based on the feature-value. The prediction information generation unit (2080) generates prediction information relating to a target person based on a feature-value, which has been calculated from an analysis image, and an evaluation function which has been acquired by the evaluation function acquisition unit (2060). The prediction information is information indicating a prediction of a prognosis of a disease of the target person or a prediction of malignancy of a disease of the target person.

  • Patent number: 8344047
    Abstract: A dispersing agent characterized in that said dispersing agent is prepared by reacting primary and/or secondary amino groups of an amine compound comprising a polyamine (C) with isocyanate groups of a urethane prepolymer (E) having two isocyanate groups in one terminal region, wherein said urethane prepolymer (E) has been prepared by reacting hydroxyl groups in a vinyl polymer (A) having two hydroxyl groups in one terminal region with isocyanate groups in diisocyanates (B), and in that an amine number of said dispersing agent is 1 to 100 mgKOH/g is disclosed. The dispersing agent of the present invention has excellent dispersibility, flowability, and storage stability when used in small quantities. A pigment-dispersed product can be prepared therefrom, independently of the kinds of binder resin or solvent used. Further, the present invention is suitable for offset ink, gravure ink, resist ink for a color filter, inkjet ink, coating composition, and colored resin composition.

  • Patent number: 8100911
    Abstract: An apparatus for treating a bone fracture comprises an intramedullary rod extending through a first bone segment of a fractured bone. A lag screw assembly extends through a first transverse aperture in the rod, while a control member extends through a second transverse aperture longitudinally offset from the first aperture. The lag screw assembly includes a lag screw engaged to the second bone segment and a locking sleeve mounted over a proximal portion of the lag screw. The locking sleeve defines a groove aligned with the second aperture. The control member includes a distal portion penetrating the bone segments, an intermediate portion configured to engage the second aperture. and an enlarged head configured to slidably engage the groove. The groove includes a terminus that contacts the head of the control member after a predetermined amount of lateral migration of the lag screw as the fracture collapses.

  • Patent number: 5927302
    Abstract: A plate-shaped article is immersed in a cleaning liquid filling a cleaning bath having an overflowing surface through which the cleaning liquid flows out, and is rinsed out. In the cleaning bath, streams mostly being directed away from a predetermined plane approximately perpendicular to the overflowing surface are formed. The plate-shaped article is then brought into the cleaning liquid having the stream maintaining a state where the plate-shaped article intersects the predetermined plane and the surfaces of the plate-shaped article are in approximately parallel to the streams mostly being directed away from the predetermined plane on the surface of the cleaning liquid.

  • Patent number: 5395452
    Abstract: In a apparatus made of silica such as a heating furnace, a wafer basket, stick or the like used for semiconductor device fabrication, a first silica layer on the side faced to a semiconductor wafer contains a large amount of the OH group, and a second silica layer on the opposed side contains a small amount of the OH group. With this structure, it is possible to reduce the amount of impurities released through the first silica layer, and to suppress the deformation of the apparatus by the second silica layer. Also, by holding a third silica layer between the first and second silica layers, it is possible to further reduce the amount of impurities released from the first silica layer.
