    摘要: There is provided a plasma display device capable of high luminous efficacy and stable driving for displaying images at various image display load factors. The plasma display device performs the sustain discharge for a light-emission display, and is configured to apply a sustain pulse voltage between a sustain electrode pair in a respective one of the plural discharge cells to generate a sustain discharge in a respective one of the following operating modes selected based upon use of the plasma display device: (a) generating a pre-discharge and then a main discharge; (b) generating a main discharge without a pre-discharge preceding the main discharge; and (c) switching between the mode (a) and the mode (b). The sustain voltage waveforms are used which compensate for an increase in voltage drop due to an increase in discharge current when the image display load factor is excessively increased.

    摘要: A method of displaying a dynamic halftone image on a display panel made of pixels divides each frame of the image into subframes and turns on and off the subframes. The method includes the steps of finding a line of pixels that simultaneously display a specific intensity level in a frame and another specific intensity level in the next frame, counting the number of pixels in the line, selecting corrective pulses, which turn on/off corresponding subframes to enable/disable corresponding intensity levels, according to the counted number and a change in the specific intensity levels between the frames, and adjusting original display signals for the pixels in the line according to the corrective pulses, respectively. The method eliminates halftone disturbance and false color contours from the image even if the moving speed of the image on the display panel is high.

    摘要: A cesium beam tube for use as a frequency standard, wherein the beam path from the cesium beam source unit to the detector is hermetically sealed.This cesium beam tube includes a rigid high frequency transition part composed of a metallic block which is used as the basic support of the tube. A first state selection magnet part and the cesium beam generator are coaxially coupled to the one end of the rigid cavity, while the second state selection magnet part and detector are coaxially connected to the other end of the rigid cavity. The rigid cavity, first and second magnet poles, cesium beam generator and the detector form the vacuum envelope by themselves, and the permanent magnets and other related parts are not in a vacuum.
