Abstract: A persistent internal polarization (PIP) electrophotography printing or copying system wherein a pair of opposite polarity electrodes, each including a plurality of elements disposed in spaced array alternating with each other in the same plane, are utilized in combination with a PIP layer such that an electric field may be simultaneously applied to the PIP layer while permitting light radiation to reach the PIP layer. In the specific practice, the pair of electrodes are positioned on top of or embedded in the surface of the PIP layer which is to be toned; that is, the top surface.

Abstract: Gas discharge panel conductor configuration and conductor system to increase efficiency of light output conductor configuration which is substantially more likely to be electrically continuous. The conductors of a conductor array on a plate forming the viewing side of the panel are formed by sets of coplanar conductor elements spaced apart so that when a discharge occurs, an observer sees more of the center of the discharge which would ordinarily be partially hidden by a solid conductive line on the viewing side of the panel. The conductor elements of a set may be connected at regular intervals to provide a plurality of electrically parallel routes for conduction in case a section of a conductor element of a set is discontinuous. The gas discharge is more visible since the applied field between selected conductor elements is across two conductors which are not congruent as seen by the observer. Moreover, since the conductor elements are relatively narrow fringe light produced at a discharge site is better seen as to further enhance the delivery of light from the panel. Consult the specification for other features and details.
