Abstract: A SOLID STATE ELECTRICAL DEVICE WHICH EXHIBITS THE PROPERTY OF HAVING DIFFERENT AND SUSTAINED STATES OF ELECTRICAL CONDUCTIVITY AND METHOD FOR MAKING SAME IS DISCLOSED. MORE PARTICULARLY, A METHOD IS DISCLOSED FOR FABRICATING AN IMPROVED SOLID STATE THIN FILM ELCTRONIC STORAGE MEDIUM WHICH CAN RETAIN BY CONDUCTIVITY MODULATION A HIGH RESOLUTION IMAGE MOMENTARILY IMPRESSED THEREUPON BY MEANS OF EITHER OPTICAL OR ELECTRON BEAM INPUTS FOR AN EXTENDED PERIOD OF TIME (SEVERAL TENS OF SECONDS) PROVIDED THAT AN APPLIED ELECTRIC FIELD IS MAINTAINED ACROSS THE SOLID STATE ELEMENT. THIS PHENOMENNON IS HEREINAFTER REFERRED TO AS "FIELD SUSTAINED CONDUCTIVITY." REMOVAL OR REVERSAL TO
OF THE APPLIED ELECTRICAL FIELD RESTORES THE SOLID STATE ELEMENT TO ITS NORMALLY INSULATING CONDITION.

Abstract: The liquid crystal device comprises a liquid crystal layer, a thin photoconductor layer, and a thin insulator layer sandwiched between the transparent supporting covers having a transparent electrically-conductive layer thereon. The photoconductor layer is cadmium sulphide (CdS) and the insulator layer is zinc sulphide (ZnS).

Abstract: The process for producing the liquid crystal device includes the steps of coating a high impedance material, such as evaporated zinc sulfide, onto a conductive coating supported upon the glass cover plate of the liquid crystal device. Next, the photoconductor layer of e.g. cadmium sulfide is vacuum-deposited. These layers are subjected to post-deposition thermal processing in the form of heat-treating in a substantially hydrogen sulfide atmosphere. Following thermal processing, the liquid crystal layer and the second cover plate are installed to complete the device.

Abstract: A solid state electrical device which exhibits the property of having different and sustained states of electrical conductivity and method for making same is disclosed. More particularly, a method is disclosed for fabricating an improved solid state thin film electronic storage medium which can retain by conductivity modulation a high resolution image momentarily impressed thereupon by means of either optical or electron beam inputs for an extended period of time (several tens of seconds) provided that an applied electric field is maintained across the solid state element. This phenomenon is hereinafter referred to as ''''field sustained conductivity.'''' Removal or reversal of the applied electrical field restores the solid state element to its normally insulating condition.

Abstract: The optical processor employs a photoconductor-activated liquid crystal as a spatial filter to control transmissivity of coherent light through the processor. The liquid crystal filter pattern determines the pattern input to Fourier transform and can optionally also define the transmissivity of a Fourier processing filter. This permits near real time transform.
