Abstract:
A plasma display panel includes: a transparent first substrate and a second substrate. A plasma discharge space is sealed between the first substrate and the second substrate. A first dielectric layer is formed on a discharge side of the first substrate. At least one pair of striped-shaped transparent first discharge maintaining electrodes are formed between the first substrate and the first dielectric layer. A second dielectric layer is formed on a discharge side of the first dielectric layer. At least one pair of stripe-shaped second discharge maintaining electrodes are formed between the second dielectric layer and the first dielectric layer so as to correspond to the first discharge maintaining electrodes. The second discharge maintaining electrodes have an electric resistance lower than that of the first discharge maintaining electrodes. At least one pair of bus electrodes are overlapped to the second discharge maintaining electrodes along a direction of length of two edges adjacent to each other of the pair of first discharge maintaining electrodes.

Abstract:
A plurality of scanning electrodes and a plurality of sustaining electrodes parallel to each other are located on an inner face of a first glass substrate. Each of the scanning electrodes and each of the sustaining electrodes form a pair. A dielectric layer and a protection layer are formed on the first glass substrate in this order, covering the electrodes. A plurality of data electrodes perpendicular to the scanning electrodes and the sustaining electrodes are located on an inner face of a second glass substrate which is located opposed to the first glass substrate with a discharge space interposed therebetween. In an AC-type PDP having such a structure, at least one of the plurality of scanning electrodes and the plurality of sustaining electrodes are divided into a plurality of groups, and pulses having different phases are applied to the electrodes in different groups, thereby causing sustaining discharge. The scanning electrodes and the sustaining electrodes may be comb-like with teeth. The comb-like scanning electrodes and the comb-like sustaining electrodes are opposed to each other with a small gap interposed therebetween in the manner that the teeth thereof are in engagement with each other. In such a case, the data electrodes are located opposed to and in a longitudinal direction of the teeth of the scanning electrodes.
Abstract:
Flash tubes for photographic use, in particular a flash tube is adapted to provide a light output adapted to FP-sync, Flat Peak. The flash tube includes a length of glass tubing enclosing a gas for use in the flash tube, a cathode inside a first end part of glass tubing and an anode inside a second end part of glass tubing. The cathode includes an element that helps to ionize the gas that is wound around the cathode, such that a spark stream starts from the upper part of the cathode and is prevented from spreading down wards on the cathode and changing the arc length during the light output adapted to FP-sync.
Abstract:
An arc chamber has a liner operably coupled to body. The liner has a second surface recessed from a first surface and a hole having a first diameter. The liner has a liner lip extending upwardly from the second surface toward the first surface that surrounds the hole and has a second diameter. An electrode has a shaft and head. The shaft has a third diameter that is less than the first diameter and passes through the body and hole and is electrically isolated from the liner by an annular gap. The head has a fourth diameter and a third surface having an electrode lip extending downwardly from the third surface toward the second surface. The electrode lip has a fifth diameter that is between the second and fourth diameters. A spacing between the liner lip and electrode lip defines a labyrinth seal and generally prevents contaminants from entering the annular gap. The shaft has an annular groove configured to accept a boron nitride seal.

A rear substrate of plasma display panel comprises a substrate, a plurality of address electrodes, a plurality of auxiliary address electrodes, a rib and a fluorescent layer. The rib is disposed on the substrate to define a plurality of discharge spaces. Each of the address electrodes is disposed in each of the discharge spaces. The auxiliary address electrodes are disposed between the substrate and the rib. When an address signal is inputted to the address electrodes, the auxiliary address electrodes are grounded for reducing the probability of error discharge. During sustain period, the auxiliary address electrodes are coupled to a positive voltage for preventing ion bombardment of phosphors layer.
