Abstract:
A discharge lamp comprising an elongated bulb shaped so that the ends thereof are substantially closer together than if the bulb were straight and containing electrodes respectively near said ends thereof, and a starting air comprising conductive members respectively adjacent to said bulb behind the plane of each of said electrodes, and means electrically interconnecting said conductive members.
Abstract:
The indicia display device of the present invention comprises a sealed compartment having a dielectric substrate therein with anodes and cathode segments imprinted therein. The anodes are imprinted on the dielectric substrate and a layer of dielectric material is imprinted over the anodes. The cathode segments are then imprinted over the layer of dielectric material. An ionizable gas is within the compartment, and produces a cathode glow adjacent the cathode segments whenever an electric potential of a predetermined magnitude is imposed between the cathodes and anodes.
Abstract:
A significant increase in brightness of the arc and a more focusable light-emitting region are provided in compact arc lamps by causing magnetic lines of force to diverge from the cathode tip from magnetic field producing means disposed within the cathode structure.
Abstract:
The present invention relates to a plasma display panel comprising two substrates defining a gap in which an ionizable gas is disposed. On at least one of the substrates there are a plurality of electrodes disposed on the side thereof closer to said gap. Covering said electrodes are dielectric means which contact said gap. The dielectric means comprises a first portion having a high secondary electron emissivity and a second portion having a secondary electron emissivity lower than said first portion. The plasma display panel according to the present invention can be used to improve the definition of a displayed pattern in the plasma display panel, or as a self shift plasma display panel, and or as a pattern generator in an information processing system.
Abstract:
A light source which includes, generally, an evacuated lighttransmitting envelope, the interior surface of which is coated with phosphors of the type which are excited by ''''active'''' (dissociated) gases to produce visible light. The envelope further includes a gas-fired high temperature energy source of radiant energy, and a gas which dissociated in the presence of this energy source of radiant energy.
