That is, in the usual mode of operation, each element of a total electron image is transferred through a single one of the energy-conducting wires and'the wire sizes are selected to be such as to produce an acceptable allover close relation thereof or picture-high grain effect. It can be seen from the above that a greater concentration of energy in each of the wires could be accomplished if less of an electron charge which is imposed upon a face plate was allowed to strike the insulation around the wires and more of the charge was caused to be gathered by the wires.
That is, if a minimum area of insulation was exposed to the electron beam adjacent the energy-receiving side of a face plate with the energyreceiving end faces of the'wires enlarged to accomplish this. In this way, substantially the full electron output of a cathode ray device could be utilized. Accordingly, it is a principal object of this invention to improve the energycolle'cting capabilities and cmciencies of face plates of the above general character by providing said face plates with improved energy-collecting and transferring elements and method of making the same.
Another object is to accomplish the above by minimizing the exposed areas of insulation on at least one of the face portions of plate-like devices. A further object is to provide face plates having energyconducting elements with enlarged closclyrelated head portions more specifically for the purpose of collecting and transferring the major portion of all image information initiated and emitted as an electron beam within conventional cathode ray tubes or like devices so as to permit utilization of substantially the full electron output capabilities of such devices.
In accordance with the above, it is a still further object to provide devices of the above character for producing clearer, more intensified and detailed reproductions of electron information produced by electron-emitting devices. Other objects and advantages of the invention will become apparent from the following description when taken in conjunction with the accompanying drawings in which:.
FIG; 11 is a diagrammatic cross-sectional view of the device of the invention illustrated in a position of use as coupling meansfor transferring energy from one section of an electron device into another section thereof;. Referring more particularly to the drawings wherein like characters of reference designate like parts throughout the several views, it will be seen that the device of the invention, as shown more particularly in FIGS. The face plate 20 may be edge-sealed as illustrated in FIGS.
In the case of an electron tube, such as illustrated in FIG. By modulation of the flow of electrons through the use of conventional cathode ray tube operating circuits, image information is applied. In the case of the present invention, the inner face portion of the'plate 2t embodies a closely knit side-by-side arrangement of the headed parts 34 of the energy-conducting elements It will become readily apparent hereinafter that the headed parts 34 of the elements 30, being larger in size than the ad oining body portions of said elements and arranged in unconnected but in close side-by-side relation with each other will function individually as collecting means for the elements 30 and, in effect, cause'electrons impingmg thereon to be funnelled into the body parts of the respective elements With a construction of this character, it can be seen that all but a negligible amount of electrons fired from the gun 36 will engage and be picked up by the headed parts 34 of the elements 30, there being a minimum of spacing between said headed 'parts through which electrons may pass and strike the insulating material 32 of the face plate The structure of FIG.
In view of the fact that the elements 30 may be required to be as small as one thousandth of an inch in diameter or less in some cases and must be relatively closely spaced from each other in the assembly of FIG. The glass cladding is applied to the wires 42 in conventional manner such,'as by shrinking a tubular glass part onto each of the wires or by dipping the wires into molten glass.
A preferred selection of materials for subsequent'use in devices such as electron tubes or the like'would consist of stainless steel wires 42 clad with soda-lime glass or other metal and glass combinations having similar expansion and heat-softening characteristics.
Since most cathode ray tubes are provided with envelope parts formed of glasses with expansion coefficients similar to soda-lime glass and the face plate 29 is usually secured thereto by fusion, it should be apparent that the use of soda-lime glass or glasses having similar heat-softening and expansion characteristics are preferred in the constructionof theface plates By matching the characteristics of the insulating glass in the face plates to those of the glasses of the articles to receive the face plates, problems of subsequent assembly of the parts are minimized and fused joinders can be made without excessivelydistorting one or the other of said turing thereof.
Other combinations of materials which may be used in the fabrication of the glass clad wires 40 would be tungsten and Pyrex glass for the respective wire part 42 and cladding Further, by way of example, other metals which mightbe used along with known compatible crownparts or causing fractype or soda-lime cladding glasses would be the following:.
Once having formed a plurality of glass-clad wires 40, the assembly of FIG. The wires may be of shapes other than the circular shapes shown. For example, square or hexagonal wires 40 would inherently intcrfit Cir In fusing an assembly such as FIG. Also, an array of wires may be glass-insulated by placing a frit between each 'of the wires and firing the assembly to fuse the frit and wires together into a solid mass. In place of the frit, molten glass may be poured over the wires.
Once having formed the structure of FIG. Next, the structure of FIG. Commercial concentrated hydrofluoric acid is used forthis operation and the time period of immersion therein is controlled in 'accordance with the depth of etching desired. Hydrofluoric acid will not appreciably attack the steel elements 30 but will produce the desired removal of the glass insulation Iron fluoride formed on elements 30 during the etching of glass 32 in hydrofluoric acid is removed subsequent to the glass etching operation.
Being readily soluble in either sul phuric acid or water, the iron fluoride is removed by immersion of the face plate structure in concentrated sulphuric acid or, alternatively, in water, preferably hot water. The resultant protrusion of the elements 30 at one side 48 for example of the structure shown in-FIG. This protrusion ofthe elements 30 at the side 46 FIG. Olt inch for elements 30 which are spaced apart in the insulation 32 a distance of approximately. These dimensions are all given by way of example.
