    摘要： An x-ray generator includes a voltage source and a voltage divider network coupled thereto, a housing, and an insulator carried within the housing. An emitter cathode is carried within the housing and emits electrons and undesirable conductive particles. In addition, there is a shielding electrode carried within the housing downstream of the emitter cathode and coupled to the voltage divider network. A target is carried within the housing downstream of the at least one shielding electrode. The voltage divider is configured so that the emitter cathode and the shielding electrode have a voltage difference therebetween such that an electric field generated in the housing accelerates electrons emitted by the emitter cathode to toward the target. The shielding electrode is shaped to capture the undesirable conductive particles emitted by the emitter cathode that would otherwise strike the insulator.

    摘要： 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 from the initial sintering temperature to 1,000*C or more so as to cause a portion of the sodium halide in the sodalite to be evaporated therefrom thereby resulting in an non-stoichiometric crystal having vacancies in the positions which sodium and halide ions normally occupy in the crystal.

    摘要： A beam addressable display and storage tube having pointwise erase capability. Each localized storage element has associated therewith an erase element which is energized by a writing beam or another beam to provide output energy for erasing the information contained in the associated storage element. In addition to storage and display, memory applications exist. Any beam addressable storage element can be used including those which form color centers or which have their color centers altered upon impact of a beam of energy.

    摘要： This disclosure is directed to articles of manufacture, chiefly display devices, containing minute ''''naked'''' droplets or inclusions of cholesteric liquid crystal material in a substantially continuous polymeric matrix, said liquid crystal material changing color or shade of color not only upon application of an electric potential but also upon removal of the field. The image produced has a comparable outline to that of the path of the electric field. Three chromatic states are evident, the normal color (before the electric potential is applied), the color given off when the electric field is applied, and the color observed when the electric field is removed. All three chromatic states are readily discernible from one another. The polymer matrix protects the cholesteric liquid crystal droplets from aging and enhances electric field behavior because the third chromatic state (electric potential removed) has a greater longevity with the matrix-bound material versus unprotected material of identical composition but no polymeric matrix. Other advantages are also discussed.

    摘要： A cathode ray tube is described comprising a target screen including a transparent conductive layer, a scotophor layer, and a luminescent layer. A first electron beam is directed at the target screen with sufficient energy to darken preselected areas of the scotophor layer. Such areas are made visible by flooding the luminescent layer with a second electron beam of lower energy. Selected areas also may be further brightened by selectively operating the first beam at an energy level insufficient to darken the scotophor.
