Abstract: A planar electron emitter, based on the existence of quasi-ballistic transport of electrons is disclosed. In its preferred embodiment the planar electron emitter structure consists of a body of finite gap pure semiconductor or insulator, the said body of macroscopic thickness (~1 mm) being terminated by two parallel surfaces and of a set of two electrodes deposited/grown on the said two free surfaces such that when a low external electrical field (~100 V/cm) is applied to this structure, consisting of two electrodes and the said semiconductor or insulating body sandwiched between them, a large fraction of electrons injected into the said semiconductor or insulator body from the negatively charged electrode (cathode) is quasi-ballistic in nature, that is this fraction of injected electrons is accelerated within the said semiconductor or insulator body without suffering any appreciable inelastic energy losses, thereby achieving sufficient energy and appropriate momentum at the positively charged electrode (anode) to be able to traverse through the said anode and to escape from the said structure into empty space (vacuum), said semiconductor or insulator body comprises a material or material system having a predetermined crystal orientation.

Abstract: In a gas discharge tube 1 in accordance with the present invention, a side tube 22 is formed from a metal, the outer periphery of the stem 4 is provided with a joint portion 15b made of a metal, and the latter is joined to a metal-made joint portion 16 of the side tube 22 by welding, whereby the assembling is made easier by welding, while the gas discharge tube 1 itself can attain smaller dimensions. Also, since the side tube 22 is small and made of a metal, its handling improves greatly. Further, since side tube 22 is formed from a metal, the gas discharge tube 1 is encouraged to have a wider range of processed forms and attains a prospect for mass production.

Abstract: An improved lighting system (10) which in the preferred embodiment includes a cathode (12) having an external surface (34) being coated with a cathode outside film (40) for emitting electrons therefrom. A first anode (14) extends internal to the cathode (12) for heating the cathode (12) to thereby emit electrons from the external surface (34). A second anode (16) is positionally located external to the enclosed cathode (12) for accelerating the electrons emitted from the cathode external surface (34). A bulb member (18) encompasses the cathode (12), the first anode (14), and the second anode (16) in a hermetic type seal. The bulb member (18) has a predetermined gas composition contained therein with the gas composition atoms being ionized by the cathode emitted electrons. The gas composition ionized atoms radiate in the ultraviolet bandwidth of the electromagnetic spectrum. The bulb member (18) is coated with a fluorescent material (20) for intercepting the ultraviolet energy responsive to the ionization of the gas composition atoms. The fluorescent material (20) radiates in the visible bandwidth of the electromagnetic spectrum to give a visible light output.

Abstract: A plasma is produced by applying a voltage to points, which are separated from one another, of a microporous body. This can be done, for example, by applying a voltage of between 50 and 100 V across a microporous layer of a silicon wafer.
