The electron beam device further comprises a cathode housing having an elongate shape and comprising a free end and an attachment end remote to the free end, and the attachment end comprises an outwardly extending flange (116) provided with threaded openings for set screws (124) and non-threaded openings for attachment bolts (122), for attaching the attachment end to a corresponding socket (118) of the tubular body, wherein means (120) configured to bias the attachment end away from the socket are arranged in the tubular body.
Abstract:
An improved design for maintaining separation between electrodes in tunneling, diode, thermionic, thermophotovoltaic and other devices is disclosed. At least one electrode is made from flexible material. A magnetic field is present to combine with the current flowing in the flexible electrode and generate a force 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 is designed to maintain a constant separation over the entire overlapping area of the electrodes. 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:
Each of the electrodes (5), (6), (7), differing from each other in their degree of rigidity is provided between a cathode (2) and a fluorescent material surface (1) through a connecting spacer (3), and the electrodes (5), (6), (7), are joined and secured together by firing. In this case, a plurality of kinds of connecting spacers (3) (spacers (3'), (3''), (3''')), are prepared which differ from each other in the thickness ratio between constituent members, i.e., a ground metal (12), an insulating layer (13) and glass frit (14) within such a range that the quality of each of the constituent members is not changed and there is no change in the distance between the electrodes (5), (6), (7), different in rigidity from each other. Each of the plurality of kinds of connecting spacers (3) is employed, and the electrodes (5), (6), (7), and the connecting spacers (3) are joined and secured together by firing in a state wherein the turning moment is cancelled about the neutral axis of an electrode block constituted by the electrodes (5), (6), (7), different in ridigity from each other, thereby forming an electrode structure for a display device. It is possible to increase the assembling accurancy of the electrode block. The electrode structure is extremely advantageous from the viewpoint of the accuracy of positioning of the electrode block in relation to the fluorescent material surface (1).

PROBLEM TO BE SOLVED: To provide an electron gun capable of positioning a cathode in relation to a Wehnelt electrode with high positional precision.SOLUTION: The electron gun comprises: a cathode 29 that emits electrons; a first Wehnelt electrode 16 provided with a first hole 22 for transmitting the electrons; and a second Wehnelt electrode 23 having a second hole 42 positioned at a prescribed position in relation to the cathode 29 and the first hole 22, and provided closer to the cathode 29 than the first Wehnelt electrode 16. The cathode 29 and the second Wehnelt electrode 23 are integrated into a cathode unit 17 which is an assembly, and the cathode unit 17 is detachable from the first Wehnelt electrode 16. The cathode 29 can be replaced by taking the cathode unit 17 off the first Wehnelt electrode 16 and taking the cathode unit 17 out of a Wehnelt cover 13. As a result, an emitter 37 of the cathode 29 can be accurately positioned in relation to the second hole 42.
