  • Publication number: 20240085687
    Abstract: A guidance method guides a camera held by a holder holding the camera that captures a field of view of a microscope through an eyepiece lens of the microscope to an appropriate holding position with respect to an optical axis of the eyepiece lens. The guidance method comprises a computer executes: acquiring, from the camera, an image of the field of view captured by the camera held by the holder; specifying a visual field area in the image corresponding to the field of view; obtaining a center of gravity coordinate of the visual field area; and creating guidance information to the holding position based on a comparison between the center of gravity coordinate and a reference coordinate corresponding to a center of gravity of the visual field area obtained from an image captured by the camera held at the holding position.

  • Patent number: 11366098
    Abstract: A method for recovering a metal that uses a reduced amount of a chelating agent is described, where the method includes a complex forming step of forming, in a mixture, a complex between a metal in a sample and a chelating agent; a complex depositing step of depositing the complex in the mixture; and a metal recovering step of recovering the deposited complex from the mixture, thereby recovering the metal in the sample.

  • Patent number: 11237153
    Abstract: A method predicts an amount of an analyte in a urine specimen collected in a target time zone. The method includes measuring an amount of an analyte in a urine specimen collected in a predetermined time zone after an administration of a chelating agent and b) predicting, from the measured amount of the analyte in the urine specimen collected in the predetermined time zone, the amount of the analyte in the urine specimen collected in the target time zone on the basis of a correlation between amounts of analyte in urine specimens in the predetermined time zone and amounts of analyte in urine specimens in the target time zone. The amounts of the analyte in the urine specimens in the predetermined time and the target time zone are measured before predicting the amount of the analyte in the urine specimen collected in the target time zone.

  • Patent number: 10175217
    Abstract: A method for recovering a metal, capable of suppressing variations in complex recovery yields among samples is described, wherein the method comprises: forming a complex between a metal in a sample and a chelating agent for metal in a mixture containing the sample and the chelating agent; and filtering the mixture in the presence of an inorganic salt to recover the complex, thereby recovering the metal in the sample.
