Abstract:
A plasma display panel (PDP) is made of front panel (2) and rear panel (10). The front panel includes display electrodes (6), dielectric layer (8), and protective layer (8) that are formed on glass substrate (3). The rear panel includes address electrodes (12), barrier ribs (14), and phosphor layers (15) that are formed on rear glass substrate (11). The front panel and the rear panel are faced with each other, and the peripheries thereof are sealed to form discharge space (16) therebetween. Primary dielectric layer (13) is provided to cover address electrodes (12), and barrier ribs (14) are formed on primary dielectric layer (13). Primary dielectric layer (13) is made of dielectric glass containing at least bismuth oxide and having a softening point exceeding 550° C.
Abstract:
A device for remediation of gaseous or aerosol streams includes an elongated duct, at least one high potential electrode and at least one low potential electrode. The elongated duct defines a bore through which axially flows a gaseous or aerosol stream which is treated by the device to remove pollutants or particulates therefrom. A shaft rotatable within the bore of the duct includes a plurality of pins extending radially therefrom, the shaft and the pins constituting the high potential electrode. The duct may similarly include a plurality of pins extending radially into the interior bore of the duct, whereby the duct and the pins constitute the low potential electrode. The shaft is rotated by a motor relative to the duct, or the duct and shaft may be rotated together by the motor. The high and low potential electrodes are connected to a high voltage power source to effect a corona discharge between the high and low potential electrodes.
Abstract:
Color plasma display panel filled with a mixture of three gases, is disclosed, the PDP having a space for filling a discharge gas formed by sealing around first and second substrates fitted parallel to each other, electrodes for use in discharge of the discharge gas on an inside surface of at least one of the substrates, and fluorescent layers for being excited by ultraviolet rays from the gas discharge, wherein the discharge gas is a mixture of three gases of xenon, helium and neon, with concentrations of the xenon and helium being the same, whereby obtaining a long lifetime, a stable operation voltage and an appropriate luminance.
Abstract:
A gas discharge device includes an anode, an enclosure member having an aperture therein and substantially enclosing a volume of a gas filling, and a mechanism for injecting electrons into the volume of gas filling to produce ionization of the gas filling within the volume so that during operation of the device, the enclosure member and the ionization within the enclosure member constitute a cathode, and a conduction path is established between the interior of such cathode and the anode through the aperture of the enclosure member.
Abstract:
A thyratron includes an envelope containing a gas filling, an anode, an intermediate grid, control grids and a cylindrical structure which acts as a cathode heat shield in a conventional thyratron. In operation the intermediate grid is maintained at cathode potential and, when triggering pulses are applied to the control grids, the gas filling ionizes and the thyratron becomes conducting. The main part of the current comes from the intermediate grid which acts as a "hollow" cathode, and enables the thermionic cathode conventionally used to be dispensed with if desired.
