  • Patent number: 4090109
    Abstract: A gas discharge display/memory device in which the driving circuitry is coupled to the panel electrodes through a plurality of gas discharge cells. Along one edge of each of the panel electrode arrays, there are formed a plurality of gas discharge shift cells each defined by a pair of crosspoints, one crosspoint formed by one of a plurality of shift electrodes and a common electrode means and the other crosspoint formed by the common electrode means and one of the panel electrodes. The shift electrodes associated with each electrode array are connected to individual shift voltage generators which generate phased shift voltages to shift a discharge along the common electrode. The discharge associated with each electrode array can be transferred to a selected panel electrode by applying a transfer pulse voltage to the electrodes forming the second crosspoint such that a discharge is initiated in the panel cell defined by the crosspoint of the selected panel electrodes.

  • Patent number: 4056806
    Abstract: An interface circuit and method for multiple discharge gaseous display and/or memory panels utilizing the slope characteristics of individual discharge units in a multiple discharge panel to control the status of individual units without effecting the status of other individual discharge units.

  • Patent number: 4025669
    Abstract: Multiple pass method of applying printing paste upon a substrate wherein the method includes the application upon a substrate of a printing paste composition containing an inorganic particulate material, a pyrolyzable organic binder and a solvent system for the organic binder which comprises a low boiling temperature solvent and a high boiling temperature solvent. The method includes the steps of applying a first layer of the printing paste composition and the thermal removal of substantially all of the low boiling temperature solvent, but not the high boiling temperature solvent or binder, prior to superimposing the next pass or layer of printing paste having the same characteristics as the first layer thereover. Following the application of the desired number of layers and removal of low boiling temperature solvent in this manner, the high boiling temperature solvent and the binder are thermally removed and the inorganic particulate material is fused to the substrate.
