  • Patent number: 11952398
    Abstract: A chromatographic method for collecting blood coagulation factor VII (Factor VII) and/or activated blood coagulation factor VII (activated Factor VII) from plasma-derived fractions with high yield is provided. In accordance with the method of the present invention, Factor VII and/or activated Factor VII of interest can be collected with a recovery rate of as high as 90% or more by letting Factor VII and/or activated Factor VII which fails to be adsorbed to a first anion exchange resin and remains in a non-adsorption fraction be adsorbed in a second anion exchange resin.
    Type: Grant

  • Publication number: 20240097595
    Abstract: To provide a power conversion device that is effective for improving controllability of power in power conversion for multilevel voltage output. A power conversion device includes a switching circuit configured to supply a current to a motor by connecting and disconnecting a first point having a first potential, a second point having a second potential greater than the first potential, and a neutral point having a neutral potential between the first potential and the second potential to and from the motor, a neutral potential control unit configured to control the switching circuit in a manner to maintain the neutral potential within a target range, and a current control unit configured to increase a supply current to the motor without affecting a driving force generated by the motor at least when controlling the switching circuit 16 by the neutral potential control unit.
