    摘要： An electronic image device in which an electron beam is generated within an envelope and caused to scan a target in a predetermined linear manner, and in which a mesh electrode is positioned between said electron gun and the target or between a photocathode and the target to cause a linear charge pattern. The mesh electrode is comprised of a first set of parallel equally spaced wires positioned at a positive angle of 50* to 70* to the linear scan of the beam and a second set of parallel equally spaced wires positioned at a positive angle of 110* to 130* to the linear scan.

    摘要： A multimode oscillator is disclosed, comprising an array of interconnected oscillator elements distributed over at least two dimensions. The oscillator elements include a grid or network of impedance elements. Three or more inductive (capacitive) elements may radiate from each junction point in the grid, and a capacitive (inductive) element may be shunted to ground from each junction point. Other arrangements of impedance elements are also possible. For pattern recognition, the oscillator elements may also include radiation sensitive elements for selectively controlling the activation of the oscillator elements. Thus, the incident pattern of light, infrared, ultraviolet, X-ray, sound or other radiation controls the number and selection of the simultaneous modes of oscillation in the multimode oscillator. The radiation sensitive elements may be shunted across the capacitive, inductive or other impedance elements and may take the form of radiation sensitive transistors, diodes, resistors, thermistors, switches, microphones or other devices. The multimode oscillator may be either passive or active. Sustained oscillations may be produced in a passive multimode oscillator by providing feedback means between the output and input of the oscillator. An active multimode oscillator employs active elements capable of sustaining the oscillations in the oscillator. Such active elements may include various negative resistance elements such as tunnel diodes. For pattern recognition, active elements may be employed which are also radiation sensitive. Alternatively, the multimode oscillator elements may include both active elements and radiation sensitive elements arranged to control the activation of the active elements. The multimode oscillator may utilize superconductive elements which may be arranged to form a superconductive grid or network to provide an array of inductive elements. The capacitive elements may be provided by the distributed capacitance between the superconductive grid and a superconductive ground plate or surface.

    摘要： Image intensifier device and method for image intensification in which a bundle of ionizing radiation containing an intelligence pattern impinges upon a fluorescent layer of an anode luminary structure to produce fluorescence and whose fluorescent output excites the further emission of photons from an adjacent image intensifier structure of the solid state type, the latter being connected in series with a unipotential source of high voltage and high frequency and said high voltage effecting further light emission from said intensifier structure, said unipotential source being further connected to a conducting layer of said fluorescent anode and to an actuating relay in a series arrangement such that said unipotential of high frequency is released to said image intensifier in an instantaneous ''''surge flow'''' concurrent with the transmission of the ionizing bundle through the face of an evacuated tube containing said fluorescing anode luminary unit and said image intensifier structure in cascade arrangement and further; said image intensifier being connected to a source of high alternating field frequency to further activate said image intensifier to produce light emission and an intensified image therefrom; the said activation being due to excitation of a dielectric layer so that the ionizing bundle evokes ''''charge transport'''' therethrough to an adjoining radiation-transparent opaque layer, and a photoelectroluminescent phosphor layer, said activation being reinforced by the concurrently applied high voltage potentials to the conductor boundary layers of said intensifier structure, to produce a stored conductivity pattern upon an image target having a longtime storage function for scansion by a cathode-ray beam of electrons, said pattern being a replica of the original image inherent in the ionizing bundle of rays.

    摘要： A stripe-shaped color separation filter for use with an image pickup tube is disclosed which is covered at its one surface with a layer of transparent material such as glass or SiO.sub.2 having a surface thereof which is flat enough to be practical for use with the image pickup tube. The layer of glass or SiO.sub.2 is formed on the filter by directly applying melted materials thereon, melting down (sintering) powdered materials, chemical vapor deposition, sputtering, or vacuum deposition.
