ILLIFWK R m KEN ETTORNEY United States Patent CATHODE RAY TUBE William Ross Aiken, Berkeley, Calif., assignor, by mesne assignments, to Kaiser Aircraft & Electronics Corporation, a corporation of New York Application December 4, 1953, Serial No. 396,120

147 Claims. (Cl. 315-41) The present invention generally relates to electric space discharge devices and more particularly relates to cathode ray tubes and beam deflection systems therefor. Certain features of the present invention relate primarily to cathode ray tubes for use in the fields of monochrome and polychrome television image presentation and control components therefor.

Heretofore, cathode ray tubes of general application, and particularly cathode ray tubes adapted for use in monochrome and polychrome image presentation, primarily have been of types wherein the electron source or sources and associated deflection systems are arranged to deliver the beam substantially perpendicular to or at substantial angles on the order of 45 or more with respect to the viewing screen.

Commercially practicable cathode ray tubes for presentation of color video signals and capable of use with dot-sequential or simultaneous color systems, such as the system recently developed by the NTSC, as heretofore proposed have all required use of dissimilar phosphor areas of line or elemental dimension, and further require complex grid or masking structures of fine constructional detail. Such presentation systems are necessarily diflicult to produce because of such fine constructional detail, and are complicated to maintain in proper operating condition because of inherent critical alignment of the scan pattern of the electron beam or beams with the grid or masking structures throughout the raster area.

It is an object of this invention to present cathode ray tubes of simplified design.

It is another object of this invention to present cathode ray tubes of lesser volume and greater compactness than found in conventional cathode ray devices of comparable viewing area.

It is also an object of this invention to present cathode ray tubes which are extremely shallow in depth.

It is another object of this invention to present cathode ray tubes of design capable of ease of manufacture in large quantities.

It is another object of this invention to present cathode ray tubes of improved design adaptable for polychrome image presentation of either additive or subtractive type.

It is another object of this invention to present cathode ray tubes of simplified design suitable for polychrome image presentation capable of use with either simultaneous or sequential televsion video signal systems.

It is a further object of this invention to present cathode ray tubes of improved design suitable for polychrome image presentation and not requiring use of dissimilar phosphor areas of line or elemental dimension or use of fine detail grid or masking structures associated with a viewing screen.

It is a further object of this invention to present color image presentation systems which may be arranged to inherently provide superposed color images and image raster linearity.

It is a further object of this invention to present cathode 2,795,731 Patented June 11, 1957 ray tubes of improved design suitable for three dimensional image presentation.

It is an additional object of this invention to present cathode ray tubes of improved design suitable for polychrome radar signal presentation.

It is an additional object of this invention to present television camera image tubes of improved design, suitable for either monochrome or polychrome video signal generation.

It is an additional object of this invention to present control components particularly adapted for control of deflection of one or more electron beams in cathode ray scanning systems of the types presented.

It is yet another object of this invention to present multi-anode space discharge switching devices, particularly adapted for use with cathode ray scanning systems in accordance with the present invention and of wide application in electronic control circuits.

These and other objects of the invention will be apparent from the following description and accompanying drawings which serve to illustrate various exemplary embodiments thereof.

Fig. 1 is a diagrammatic presentation in block form of the general arrangement of a cathode ray tube and control components therefor as contemplated by the present invention, wherein an electron beam from a suitable electron source is delivered throughout the horizontal dimension of an image screen by a deflection system comprising at least one deflection element arranged to accomplish such deflection in a plane substantially parallel and adjacent to the image screen, and wherein the electron beam is further delivered throughout the vertical dimension of the image screen by a deflection system comprising at least one deflection element arranged to deflect said beam toward said image screen.

Fig. 2 is a schematic exploded perspective view of a monochrome cathode ray tube and associated components embodying certain features of the present invention, wherein the electron source is arranged to provide an electron beam in substantially parallel proximity with the viewing screen, wherein the horizontal sweep deflection system comprises a plurality of electrostatic deflection plates, the deflection control voltage to each of which is provided from a lineally arranged triode control tube comprising a variably spaced control grid, and wherein the vertical sweep deflection system comprises a plurality of electrostatic elongated plates arranged in a plane substantially parallel and slightly spaced from the viewing screen, the control voltages for said plurality of vertical sweep deflection plates being provided from a lineally arranged triode control tube comprising a variably spaced control grid.

Fig. 3 is a schematic exploded perspective view of a further embodiment of the present invention as applied to a monochrome cathode ray tube and associated components, wherein the electron source is arranged to provide an electron beam in substantially parallel proximity with the viewing screen, wherein the horizontal sweep deflection system comprises a plurality of electrostatic deflection elements, the deflection voltages being provided from a radially arranged pentode control tube comprising two inversely variably spaced control grids, the resulting initial deflection of the beam being at acute angles, and wherein the vertical sweep deflection system comprises a plurality of elongated plates arranged in a plane substantially parallel and adjacent to the viewing screen, the control voltages for said plurality of vertical sweep deflection plates being provided by scanning a plurality of collector plates respectively associated therewith by an electron beam.

Fig. 4 is a schematic exploded perspective view of a further embodiment of the present invention as applied
