Multibeam cathode ray tube having a common beam limiting aperture therein

阅读：359发布：2022-01-10

专利汇可以提供Multibeam cathode ray tube having a common beam limiting aperture therein专利检索，专利查询，专利分析的服务。并且An improved multibeam cathode ray tube electron gun is provided wherein a plurality of similar electron beams forming an array pattern are directed to crossover at a common point within the plural beam gun structure. Positioned at the point of crossover is an electrode member having a single aperture therein which uniformly and simultaneously sizes or areally limits each of the individual beams passing therethrough. This reduction in crosssectional area of each beam comprising the pattern array results in a screen pattern array exhibiting markedly improved spot quality and resolution.，下面是Multibeam cathode ray tube having a common beam limiting aperture therein专利的具体信息内容。

权利要求

1. An improvement in a cathode ray tube multibeam electron gun having therein a common emission plane, a parallelly related planar arrangement of separate control electrode members defining an array of individual electron beams, at least one acceleratingcollimating electrode plane, a plurality of substantially cylindrical electron lens-forming electrodes, and a terminally oriented spiral accelErator sequentially positioned forward thereof to effect a plurality of sequentially spaced common crossovers of the beams in directing the array of beams to impinge and focus on the cathodoluminescent screen of said tube in a controlled predetermined manner, said electron gun improvement including means for discretely controlling the sizes of the individual beams comprising: a planar beam-limiting electrode member positioned at the area of the first crossover of said plural beams within one of said cylindrical lens-forming electrodes, said beam-limiting electrode having a single aperture oriented substantially axially therein at substantially a point of crossover of the plural beams in said lensing electrodes to uniformly and simultaneously limit the cross-areal size of each beam passing therethrough.

2. The improvement in the multibeam electron gun according to claim 1 wherein said beam-limiting aperture has a peripheral edge of substantially minimum annular area free of protuberances.

3. The improvement in the multibeam electron gun according to claim 1 wherein said beam-limiting aperture is substantially round.

4. The improvement in the multibeam electron gun according to claim 1 wherein said beam-limiting aperture is substantially infundibular in shape with the larger diameter of said shaping being oriented toward said screen. structure,

5. An improvement in a cathode ray tube multibeam electron gun having an axis therethrough and a terminally oriented electron beam acceleration means wherein said plural beams emanate from similar emission areas and have separate control electrode members defining an array of individual electron beams and a common accelerating electrode member with separate apertures therein, said plurality of beams having a common crossover point within the gun structue, said improvement comprising: a beam-limiting electrode member positioned in a lens forming electrode forward of said common accelerating electrode, said beam-limiting electrode having a single aperture oriented relative to said tube axis at substantially the first point of crossover of said array of plural beams to uniformly and simultaneously limit the cross-areal size of each beam passing therethrough.

6. An improvement in a cathode ray tube multibeam electron gun according to claim 5 wherein said beam-limiting aperture is substantially round and infundibular in shape.
