摘要： In a power converting apparatus having a plurality of phases on an AC side and configured to perform conversion between DC power and AC power, a current detector detects currents flowing through a DC source line through which a plurality of phase currents commonly flow. A control unit sets a current detection period and a succeeding current control period in each successive control cycle. Using first gate signals based on reference gate signals for PWM control, the control unit calculates values of the individual phase currents from the first gate signals and the detected currents during the current detection period. Then, during the current control period, the control unit performs PWM control using phase voltage commands generated by correcting phase voltage target values so as to cancel out voltage errors that occur during the current detection period.

摘要： A liquid crystal shutter includes a first support substrate having a first electrode and a second support substrate having a second electrode opposite to the first electrode. A liquid crystal layer is sandwiched between the first and second electrodes so as to have a switching region. The switching region becomes a bend alignment state from a splay alignment state when a voltage is applied to the liquid crystal layer. A nucleus region formation portion is arranged on the first support substrate to form a nucleus region in the switching region corresponding to the nucleus region formation portion in the liquid crystal layer, in which the splay alignment is more stable than in the switching region.

摘要： A radiation conversion panel allows recorded radiation image information to be read therefrom with high accuracy while reliably avoiding adverse effects of residual past radiation image information that remains in the radiation conversion panel. When a radiation conversion panel storing radiation image information therein is scanned by reading light from a reading light source, the radiation image information is read from first linear electrode layers, and scanned position information is read from a first linear electrode layer of a marker. A corrector corrects presently read radiation image information based on past radiation image information and scanned position information to acquire radiation image information free from the effect of a residue of the past radiation image information.
