Abstract: A projection television tube includes a spherically curved electronic beam target surface spaced away from the neck of the tube, a larger reflective surface spherically curved concentrically with the target surface on an end plate located close to the tube neck, a target support that preferably constitutes a face plate for the envelope, and a hollow cylindrical spacer member for closing the side of the tube envelope and for holding the target support accurately spaced from the reflective surface. The ends of the cylindrical member and the abutting surfaces of the end plate and target support are all configured to provide joint interfaces between the elements that lie in spherical planes that are concentric with the target and reflective surfaces, so that slight lateral motion of the parts during assembly and handling will not affect tube projection optics, while the spacing between the target and reflective surfaces is precisely maintained in concentric relationship.

Abstract: A color projection television receiver and projector having three color tubes mounted in fixed relation and in predetermined location relative to a screen for projecting three color pictures in registration thereon. Accurate registration of the pictures results from a projection tube structure adapted for accurate reproducability in production, whereby field adjustment is minimized. The tube structure employs a mounting barrel accurately suspended within the evacuated envelope and supporting a phosphorcoated target and a projection mirror. A Schmidt correction lens is mounted externally to the envelope of each tube.

Abstract: Apparatus for detecting any signal occurring within a wide bandwidth and playing it with a signal-to-noise performance substantially equal to that of a receiver of optimum bandwidth for that signal. The apparatus essentially comprises a special purpose cathode ray tube that functions as a plurality of different detectors that can self-optimize to detect any signal within a wide bandwidth by means of the interactions between the received signals and an electron beam having a wide range of electron velocities and traveling in a zig-zag path in the cathode ray tube.

Abstract: A CATHODOCHROMIC CATHODE RAY TUBE COMPRISES AN IMAGE SCREEN EMPLOYING IMPROVED CATHODOCHROMIC SODALITE. THE CATHODOCHROMIC SODALITE IS PREPARED BY FORMING AN AMORPHOUS MASS FROM A MIXTURE OF A SODIUM HALIDE, SODIUM HYDROXIDE, ALUMINUM OXIDE AND SILICON DIOXIDE. THE MASS IS CALCINED AT AN ELEVATED TEMPERATURE SO AS TO DRIVE OUT HYDRATED WATER FROM THE MASS. THE CALCINED MASS IS CRUSHED TO A POWDER AND THEN SINTERED SO AS TO FORM CRYSTALLINE SODALITE. THE TEMPERATURE IS RAISED SO AS TO CAUSE SINTERING TEMPERATURE TO 100* C. OR MORE SO AS TO CAUSE A PORTION OF THE SODIUM HALIDE IN THE SODALITE TO BE EVAPORATED THEREFROM THEREBY RESULTING IN A NON-STOICHIOMETRIC CRYSTAL HAVING VACANCIES IN THE POSITIONS WHICH SODIUM AND HALIDE IONS NORMALLY OCCUPY IN THE CRYSTAL.

Abstract: A Laser-CRT is described in which the laser faceplate is at high potential and the cathode is above ground. The cathodes can be modulated in a dual-drive or push-pull mode in which each of the dual video amplifiers is required to swing only half of the total required voltage, thereby writing smaller pixels faster and achieving higher resolution. Another described embodiment provides a substantially constant laser output over time, and an approximately uniform output intensity over an area. A constant-output Laser-CRT can be used to illuminate a spatial light modulator (SLM) in a projection system, and since video modulation is not required in that embodiment, neither are costly electronics and merely a voltage bias need be applied to the electron gun (e.g., the K electrode) to turn on the electron beam.

Abstract: A semiconductor laser CRT for driving at room temperature, whose target is pumped by an electron beam, in which a laser target is fixed to a beaker-shaped transparent glass support plate, and the glass support plate is sealed with a glass bulb using fused frit glass. Accordingly, there is no cracking of the glass bulb due to a difference in thermal expansion or destroying of a sustained airtight vacuum.
