Abstract
Abstract There is disclosed a gas discharge device gas mixture consisting essentially of about 20 to 35 percent atoms of argon and about 80 to 65 percent atoms of a xenon-based composition. The mixture is especially beneficial for use in a color phosphor gas discharge display/memory device because the mixture substantially lowers peak gas discharge currents while providing phosphor stimulation. The xenon-based composition consists essentially of about 95 to 100 percent atoms of xenon and about 5 to 0 percent atoms of another component, particularly one or more selected from neon, krypton, nitrogen, helium, and mercury.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
60 words
IN AN ARTICLE OF MANUFACTURE COMPRISING AN AC MULTIPLE GAS DISCHARGE PHOSPHOR DISPLAY DEVICE CONTAINING AN IONIZABLE GASEOUS MEDIUM, THE IMPROVEMENT WHEREIN THE GASEOUS MEDIUM CONSISTS ESSENTIALLY OF 20 TO 35 PERCENT ATOMS OF ARGON AND 80 TO 65 PERCENT ATOMS OF A XENON-BASED COMPOSITION, WHEREBY THE PEAK GAS DISCHARGE CURRENTS ARE DECREASED AND THE MEAN MEMORY MARGIN IS INCREASED.
Claim 2
Dependent Claim
