Abstract: A blood pressure measuring apparatus includes a pressure control unit that controls an applied pressure applied to a region of a living body in which a vein and artery exist by a cuff mountable to the region, a detection unit that detects pressure waveforms in which pulse wave components from the region overlap with the applied pressure, and an analysis unit that obtains a respiratory variation on the waveform of artery and a venous pressure based on the pressure waveforms detected by the detection unit through one-time blood pressure measurement. The analysis unit obtains the respiratory variation on the waveform of artery based on data of a first pressure waveform in a first process, and the venous pressure based on data of a second pressure waveform in a second process and the data of the first pressure waveform.

Abstract: The amount and area of irradiation of excited species to the surface of a workpiece can be increased, the irradiation can be uniformly performed on the whole surface, and the loss of effective excited species is suppressed, so that the treating performance and efficiency can be remarkably improved. A pulse voltage is applied between discharge electrodes (4) which are opposingly positioned, to produce a corona discharge between pointed ends of the discharge electrodes, and the surface of a workpiece is irradiated with excited species including plasma produced by the corona discharge, thereby treating the surface. Plural discharging units are prepared in each of which a first electrode (11) and a second electrode (12) are opposingly placed. One of the secondary terminals of a transformer (15) is connected to each of the first electrodes (11) of plural discharging units (13).

Abstract: A high frequency detection circuit detects information about a first high frequency power in a high frequency power source device supplying the first high frequency power having a first frequency and a second high frequency power having a second frequency lower than the first frequency to a load. A third high frequency signal that is a mixed signal of a first high frequency signal having the first frequency and a second high frequency signal having the second frequency is detected by a directional coupler. The third high frequency signal is converted to a fourth high frequency signal having a third frequency between the first and second frequencies using a heterodyne system. A progressive wave power of the first frequency is detected based on the fourth high frequency signal.
