  • Patent number: 11774462
    Abstract: In a pre-processing system, a state in which a sample dispensing probe 20a and a syringe pump 81 communicate with each other through a channel 91 and a state in which the sample dispensing probe 20a and a culture tank 301 communicate with each other through the channels 91, 93, and 94 can be switched by operation of the three-way valves 82 and 83. For this reason, the liquid sample in the culture tank 301 can be automatically discharged from the sample dispensing probe 20a without requiring the user to directly sample the liquid sample. As a result, in the pre-processing system, the user's manual sampling work can be omitted, and the user's work can be simplified.

  • Publication number: 20230306663
    Abstract: Provided is a data processing device for processing data acquired by an electrophoretic analysis. A graph creator (31, 33) creates an electropherogram and/or a separation image of peaks on an electrophoretic channel. A display processor (37) displays a graph showing the electropherogram and/or the separation image on which a boundary line is drawn to define the inside and the outside of an analysis target range extending along an axis of a separation direction, with the inside and the outside being shown in different visual modes. An analysis condition setter (34) receives an operation by a user for moving the boundary line on the graph displayed and sets the analysis target range whose position and size on the axis are changed according to the received operation. A data-analysis processor (35, 36) carries out a predetermined computation using all or some of peaks included in the analysis target range.

  • Publication number: 20230304787
    Abstract: In a defect detection device (10), an exciter (11) gives a test object (S) a vibration with a variable frequency. A vibration state measurer (15, 163) performs a measurement of the vibration state of the surface of the test object by an optical means while the vibration is given to the test object, and determines, for each position on the surface, a numerical value representing the vibration state based on a result of the measurement. A judgment-index-value determiner (164) determines a judgment index value by Fourier transform based on the numerical value representing the vibration state at each position, where the judgment index value is a numerical value representing a strength of the vibration for each wavenumber. A wavenumber-wavelength determiner (165) determines, based on the judgment index value determined for each wavenumber, a wavenumber or wavelength of an elastic wave induced in the test object by the vibration.

  • Patent number: 11766672
    Abstract: An apparatus for manipulating magnetic particles includes a latch mechanism. The latch mechanism has a pivoting part provided on a door and an engaging part provided on a main body. In the apparatus for manipulating magnetic particles, a first contact portion of a latch engages with the engaging part at a contact point in a state that the door is closed. The contact point is located more outside of the main body than the pivot axis. Accordingly, in a case where an external force is applied to the door in a direction to open the door in a state that the door is closed, a force is applied from the engaging part to the first contact portion, thereby generating a rotational force in a C direction to the pivoting part. As a result, in the state that the door is closed, it is possible to suppress the door from being opened without a manipulation by the user.
