Abstract: An improved design for maintaining separation between electrodes in tunneling, resonant tunneling, diode, thermionic, thermo-photovoltaic and other devices is disclosed. At least one electrode 1 is made from flexible material. A magnetic field B is present to combine with the current flowing in the flexible electrode 1 and generate a force or a thermal expansion force combined with a temperature distribution that counterbalances the electrostatic force or other attracting forces between the electrodes. The balancing of forces allows the separation and parallelism between the electrodes to be maintained at a very small spacing without requiring the use of multiple control systems, actuators, or other manipulating means, or spacers. The shape of one or both electrodes 1 is designed to maintain a constant separation over the entire overlapping area of the electrodes, or to minimize a central contact area. The end result is an electronic device that maintains two closely spaced parallel electrodes in stable equilibrium with a uniform gap therebetween over a large area in a simple configuration for simplified manufacturability and use to convert heat to electricity or electricity to cooling.

Abstract: The present invention relates to an electrode device (1, 2) for gas discharge sources and to a gas discharge source having one or two of said electrode devices (1, 2). The electrode device (1, 2) comprises an electrode wheel (7) rotatable in a rotational direction around a rotational axis (22), said electrode wheel (7) having an outer circumferential surface (24) between two side surfaces (25). An electrode wheel cover (8) is provided which covers a portion of the outer circumferential surface (24) and the side surfaces (25) of the electrode wheel (24). The cover (8) is designed to form a cooling channel (12) in the circumferential direction between the cover (8), the outer circumferential surface (24) and radially outer portions part of the side surfaces (25), and to form a gap (23) between the cover (8) and the outer circumferential surface (24) in extension of the cooling channel (12) in the circumferential direction. The gap (23) has a smaller flow cross section than the cooling channel (12) and limits a thickness of the liquid material film formed on the outer circumferential surface (24) during rotation of the electrode wheel (7). Alternatively to the gap (23) the cover (8) may be designed to inhibit the formation of such a film from the liquid material flowing through the cooling channel (12). The cooling channel (12) allows at the same time cooling of the electrode wheel (7) by the liquid material circulating through the cooling channel (12). With the proposed design of the cover (8), an efficient cooling of the electrode wheel (7) is achieved, allowing high electrical powers for operating gas discharge sources with such an electrode device.

Abstract: An arc lamp construction wherein a pair of metallic electrodes defining an arc gap are mounted within a quartz envelope and are secured within said envelope by shrinking the same into engagement with a foot portion of each electrode. The foot portions of the electrodes are tapered and include certain surface irregularities large enough to allow the quartz envelope, when shrunk thereabout, to be deformed into or around the irregularities to provide an interlocking mechanical mating therebetween to prevent longitudinal displacement of the electrodes within the envelope.
