摘要： A switching element operates to be turned on or off at a frequency in the order of megahertz. A reactor supplies a resonance current generated by resonance of the reactor with a floating capacitance between electrodes to between the electrodes. The resonance current does not flow in a direct-current power supply. By turning a capacitor and a floating inductance into a serial resonant state, the reactor ideally supplies the resonance current to between the electrodes without influence of the floating inductance. A high-frequency voltage asymmetric in positive and negative polarities is applied to between the electrodes and a current pulse can be made into a short pulse. Therefore, finish machining with high surface roughness can be performed.

摘要： In a reset period, through applying a rectangular pulse (Pya) of positive polarity to an electrode (Y) and applying a CR pulse (Pxa) of negative polarity to an electrode X, a full lighting pulse is applied between the electrodes (X and Y). The application of the voltage is stopped before a CR pulse (Pxc) reaches a final potential, to generate the pulse (Pxa). A full erase pulse (Pxb) made of a CR pulse having a polarity reverse to that of the pulse (Pxa) is applied to the electrode (X). An erase operation reverses the polarity of wall charges accumulated by a full lighting to effectively perform a potential control operation. The potential control pulse (Pxc) is applied to the electrode (X) to generate a discharge, and the state of the wall charges in a discharge cell is controlled by the discharge to generate an optimal amount of wall charges for a subsequent addressing discharge. The final voltage of the pulse (Pxc) is set equal to a voltage (−Vxg) of an address pulse (Pa). Thus, it is possible to generate a plurality of pulses and stabilize an operation of a PDP with a simple constitution.

摘要： A projection display uses a light modulating device to modulate, in accordance with image data, light radiated from a light source, project the modulated light onto a screen, and display an image. The projection display separates a unit of time configuring the image data into an effective light time when the light modulating device can express the light as an image on the screen and an ineffective light time when the light modulating device cannot express the light as an image on the screen. The projection display increases the power supplied to the light source during the effective light time over the power supplied to the light source during the ineffective light time.

摘要： A plasma display device which is capable of solving the problem of a trade-off between the increase in recovery efficiency of reactive power resulting from charging and discharging of a plasma display panel serving as a capacitive load and the adverse effects upon a gas discharge characteristic in the plasma display panel is provided. First and second sustain pulses are applied respectively to first and second electrodes (X, Y1-Yn) arranged in parallel in pairs for respective display lines so that the output time periods of the first and second sustain pulses partially overlap each other on the time axis. One of the first and second sustain pulses which rises earlier has a higher rate of voltage change at the rising and falling edges than does the other.

摘要： A 3-electrode, surface-discharge type plasma display is capable of offsetting a radiation fields which is generated at the time of displaying, to reduce radiation noises. To drive the plasma display, an X-electrode and a Y-electrode are separated to an even number (2m) and an odd number (2m-1), respectively. During a resetting period and an addressing period, pulse voltage is applied to the even-numbered and odd-numbered electrodes at the same time, whereas in a sustained discharge period, the phase of the pulse voltage applied to the even-numbered electrode is delayed by 180 degrees from that applied to the odd-numbered electrode.
