摘要： A field emission device is configured with a grid that includes nanotubes or nanowires. In one embodiment a cathode, an anode, and a nanotube or nanowire grid are responsive to inputs to produce a potential barrier between the grid and at least one of the cathode and the anode such that a set of electrons from the cathode can tunnel through the potential barrier to produce a net current at the anode.

摘要： A gridded convergent flow electron gun employs a dimpled oxide coated thermionic cathode emitter facing a centrally apertured accelerating anode. A multiapertured control grid is interposed in the space between the dimpled oxide coated cathode and the anode for pulsing the electron beam. A multiapertured shadow grid is disposed overlaying the emitting surface of the cathode emitter with the apertures of the shadow grid being in alignment and in registration with the respective dimpled areas of the emitter and the corresponding apertures in the control grid for projecting a multiplicity of non-intercepting convergent flow beamlets through the individual holes in the control grid. The shadow grid is placed in nominal contact with the cathode emitter and is made of a material having essentially the same coefficient of thermal expansion as the cathode. In a preferred embodiment, the cathode includes a nickel base member and the shadow grid is made of nickel.

摘要： An incandescent lamp having a filament made of tungsten wire containing between 1-2 percent by weight thoria has greatly improved resistance to fracture caused by shock and vibration thereby increasing the service life of the lamp. The thoriated tungsten filament has a recrystallized grain structure which is characterized by approximately equiaxed crystals of tungsten of a smaller and more uniform size and thoria particles which are more uniformly distributed throughout the tungsten matrix than can be obtained by conventional powder metallurgy.

摘要： A ceramic electrode for a gliding electric arc system. The ceramic electrode includes a ceramic fin defining a spine, a heel, and a tip. A discharge edge of the ceramic fin defines a diverging profile approximately from the heel of the ceramic fin to the tip of the ceramic fin. A mounting surface coupled to the ceramic fin facilitates mounting the ceramic fin within the gliding electric arc system. One or more ceramic electrodes may be used in the gliding electric arc system or other systems which at least partially oxidize a combustible material.
