Abstract: A cathode for an electron gun in which a lanthanum hexaboride cap has an internal recess which accommodates a pyrolytic graphite heater element. The cap is cup-shaped, while the heater element is in the form of a frustum of a cone and is resiliently maintained in abutting relationship with the cap by a corrugated tubular member and an assembly of rigid tubes. A cylindrical shell surrounds the periphery of the cap, and a pair of generally conical shielding elements are located in position to intercept stray thermal radiation from the heater element. All of these cathode components are supported in coaxial relationship with each other within the electron gun.

Abstract: There is disclosed a support structure for a directly-heated cathode in a cathode ray tube, for supporting the cathode by fastening the strip leads of the cathode to support rods piercing and rigidly fixed to a base of insulating material through resistance welding. The support rods are provided in their proper positions respectively with protrusions having top plane areas to be contacted with the surfaces of the strip leads and the cathode is supported by fastening the strip leads to the protrusions through resistance welding. The length of the top plane area of the protrusion extending in the direction along the width of the strip lead is 30 to 80% of the size of the width of the strip lead.

Abstract: A cathode for an electron source according to this invention comprises an emitter tip made of an electron emissive material, a filament for holding the emitter tip, and a binder for binding the emitter tip and the filament, the filament and the binder being made of glassy carbon. The binder can have a carbide or boride powder incorporated therein. The cathode according to this invention can be produced by using a thermosetting resin of predetermined shape as the starting material of the filament, fixing the emitter tip to a predetermined position of the thermosetting resin with the adhesive agent made of the raw thermosetting resin, and heating the resultant assembly in a non-oxidizing atmosphere to carbonize the resinous portions. This cathode is structurally very simple. Moreover, the adhesion between the filament and the emitter tip is excellent, and the emitter tip can be heated to high temperatures above 2,000.degree. C. by causing current to flow through the cathode.

Abstract: A grid-controlled electron tube is constructed with a common anode and an array of individual cathode-grid modules. The simple modules can be built with greater accuracy than large, complex electrodes. The modules can be individually tested before final assembly, and can be individually replaced in case of a failure during construction or later operation. In a preferred embodiment, the cathode is a cylindrical filament surrounded by a coaxial grid, each grid turn being mounted to a common support on the side opposite the anode. In a tetrode embodiment, additional focusing bars at the sides of the grid direct electrons into beams which pass between large screen-grid wires.

Abstract: Incandescent source of visible radiations comprises a refractory support member having a thin, refractory material layer thereover, with both the support and the thin layer adapted to be heated to high temperatures. The material comprising the thin layer is highly absorptive for visible radiations and thus is a correspondingly good emitter for such visible radiations, and the material comprising the thin layer is highly transmissive for infrared radiations and a correspondingly poor emitter for such infrared radiations. Minute optical discontinuities in the thin layer act to scatter infrared radiations and the infrared radiations which are generated in the support member are scattered back to the support member in order to contribute to the heating of same. Visible radiations, in contrast, are absorbed and emitted by the thin layer so that this layer is a very selective radiator. In this manner, infrared radiations generated in the support member are selectively scattered to contribute to the heating of the support member and thus the generation of more visible radiations which the thin layer emits.
