Abstract: Provided is a method for assisting in grasping the status of platelet activation, by developing a biomarker that more accurately reflects platelet activation in vivo, said method being usable in testing for thrombotic hemostatic diseases. The method for assisting in grasping the status of platelet activation comprises (1) measuring the concentration of soluble CLEC-2 and a platelet count in a sample obtained from a subject, and (2) calculating a value of [soluble CLEC-2 concentration]/[platelet count] by dividing the soluble CLEC-2 concentration by the platelet count. If desired, the method may further comprise (3) comparing the value with a value of [soluble CLEC-2 concentration]/[platelet count] obtained by using samples from healthy persons.

The apparatus controls the first power converter based on an output from the first current command value calculator.

Abstract: The present invention provides an electric power converting unit that does not require a change in a control method in, for example, system interconnection by calculating a target value of an output current of an electric power converter from an internal phase angle calculated from an active electric power control loop and an internal electromotive voltage calculated from a reactive electric power control loop. Thus, a stand-alone power supply system that is easy to handle can be configured.

Abstract: A turbine generating apparatus includes a control unit which controls the turbine generating apparatus as follows. During a system connection running mode, a fuel is fed to the gas turbine at a fuel flow rate corresponding to a preset load. The converter prepares a pseudo-system in which a frequency conforms to a set rotational speed of the gas turbine at the preset load, and converts an output of the generator to a direct current in a state that a number of revolutions of the gas turbine is specified by operating the generator synchronously with the pseudo-system. A power to be taken out is controlled depending on a magnitude of a turbine output. The inverter converts a DC voltage output from the converter to an AC voltage by a pulse width modulation at a system voltage and a system frequency so as to keep the DC voltage output from the converter at a predetermined voltage.
