  • Patent number: 10705544
    Abstract: In order to restrain generation of a peak in the measured flow rate, a fluid control unit measures a flow rate of a fluid in a channel and outputs a signal indicating a valve operation amount of a fluid control valve obtained based on a deviation between a preset flow rate and a measured flow rate and a control coefficient, and the control coefficient for a stable state and the control coefficient for a transitional state are so set to moderate fluctuation of the valve operation amount to the deviation more in the transitional state than in the stable state. At or shortly after a timing when the stable state is switched to the transitional state, a signal is output that indicates an operation amount for a switching time calculated based on each of the operation amounts output at a plurality of timings in the stable state.

  • Publication number: 20200199689
    Abstract: The purpose of the present invention is to provide a method for predicting the effectiveness of an angiogenesis inhibitor in a subject suffering from a tumor. Provided is a method comprising a step of testing for the presence or absence of an a mutation or loss of expression of B-Raf and PTEN in a sample of tumor tissue from the subject. By using the presence or absence of or a mutation or loss of expression of B-Raf and PTEN as an indicator, this method enables the antitumor effectiveness of the angiogenesis inhibitor to be predicted without administering the angiogenesis inhibitor to the subject.
