Abstract
Abstract A Two Directional Plasma Charge Transfer Device utilizing an ionizable gas in an enclosure having a primary channel and a plurality of secondary channels extending laterally therefrom, an input electrode which can be directly or capacitively coupled to the gas, a plurality of transfer electrodes coated with a dielectrical material on opposite internal walls of the enclosure offset from one another throughout the length of the channels and arranged so that upon application of input signals, the gaseous discharge transfers successively between subsequently offset transfer electrode pairs by the transfer of the electric charge on the wall coating of the electrode which results from the gaseous discharge, first along the primary channel and subsequently laterally from the direction of its original travel so that the device may be used preferably as a graph display or as a two directional shift register.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
191 words
A Two Directional Plasma Charge Transfer Device comprising: an enclosure hAving a primary channel containing an ionizable medium: a plurality of secondary channels extending laterally therefrom and connecting therewith: an input electrode means within said primary channel; a plurality of transfer electrode means arranged in alternating sequence and offset one from another on opposite sides of the inside walls of the primary channel and the secondary channels and capacitively coupled to said medium, the transfer electrode means in the primary channel arranged and coupled in groups of two pairs and with the last two electrode means of each of the group of pairs extending into the secondary channels; said input electrode means and said transfer electrode means arranged so that once the medium discharges between the input electrode and the nearest transfer electrode means by the application of electrical energy to the said electrode means, the application of sequentially applied electrical energy to said transfer electrode means will cause a plasma discharge between certain of said transfer electrode means and shift said plasma discharging along the length of said primary channel and then subsequently along the length of the secondary channels.
