Abstract: A field emission element including an electrode structure made of a thin film exhibiting increased adhesive strength. A thin film of niobium nitride (NbN) is formed on a glass substrate by sputtering or the like. The NbN film exhibits increased adhesive strength to a degree sufficient to prevent etching for formation of the film into electrodes from causing peeling of the film.

Abstract: A large area directly heated lanthanum hexaboride (LaB.sub.6) cathode system (10) is disclosed. The system comprises a LaB.sub.6 cathode element (11) generally circular in shape about a central axis. The cathode element (11) has a head (21) with an upper substantially planar emission surface (23), and a lower downwardly and an intermediate body portion (26) which diminishes in cross-section from the head (21) towards the base (22) of the cathode element (11). A central rod (14) is connected to the base (22) of the cathode element (11) and extends along the central axis. Plural upstanding spring fingers (37) are urged against an outer peripheral contact surface (24) of the head end (21) to provide a mechanical and electrical connection to the cathode element (11).

Abstract: This invention provides for an improved reflector-type lamp having reduced focus loss and exhibiting an increase in reflector collection efficiency. Stray light from the lamp's light source is reduced and channeled into the central angular region of the reflector where it can be more easily controlled and increase the in candle power of the lamp. A shorter, more compact filament design, wound with larger mandrel ratios, is positioned within the reflector to evenly disperse the light energy throughout the central angular region.

Abstract: A tungsten filament intended as a thermionic source, made from a wire of which the zone defining the point is of a diameter smaller than that of the basal zone and where the diameter of the transitory part of the wire changes progressively. This filament is contained in the same plane and its lower legs are welded to rigid posts in a ceramic base. A novel electrolytic sharpening process is used for the reduction of the diameter of the filament wire, and this process, which permits the progressive reduction of the dimension of a workpiece, can be used in other applications. An apparatus is used for the manufacturing of such a filament by cyclic electrolytic sharpening, as well as means enabling the bending of the wire and its positioning during the welding operation.

Abstract: Disclosed is an electron-beam cathode which emits electrons in a cone-shaped pattern whose electron density is substantially uniform throughout the cone. The cathode is comprised of a needle-shaped piece of single crystal tungsten having dopant atoms of zirconium and oxygen in the bulk thereof, and having only a single (100) surface on the needle's tip. This cathode is formed by the steps providing a needle-shaped piece of single crystal tungsten having dopant atoms of zirconium and oxygen in the bulk thereof, and having a plurality of ring-shaped (100) surfaces on the needle's tip; and subsequently transforming those surfaces into diagonally oriented planar surfaces by heating the needle in an atmosphere of oxygen to diffuse tungsten atoms from the needle's tip to its sides.

Abstract: A field emission tip on which a metal adsorbate has been selectively deposited, and a method by which it may be manufactured. In a vacuum, a clean field emission tip is subjected to heating pulses in the presence of an electrostatic field to create thermal field buildup of a selected plane. Emission patterns from the selected plane are observed, and the process of heating the tip within the electrostatic field is repeated until emission is observed from the desired plane. The adsorbate is then evaporated onto the tip. The tip constructed by this process is selectively faceted, with the emitting planar surface having a reduced work function and the non-emitting planar surfaces having an increased work function. A metal adsorbate deposited on the tip so prepared results in a field emitter tip having substantially improved emission characteristics.

Abstract: A cathode heater element is coated with a dark colored heat radiating porous layer of insulating material such as aluminum oxide and a refractory metal such as tungsten. The aluminum oxide is applied in an electrolytic bath, dried and impregnated with a tungstate solution. The layer is heated and sintered in a nitrogen hydrogen atmosphere. The heater element has improved heat transfer characteristics.
