Abstract:
Disclosed herein are magnet systems that may include a vacuum container for containing a vacuum; a supplied magnetic field (SMF) producer configured for creating a supplied magnetic field and a supplied alternating electric field (SAEF) producer configured for creating a supplied alternating electric field; and an electron source positioned so as to release electrons in the vacuum container into the SMF and the SAEF such that the electrons form an electron coil in the vacuum, wherein the electron coil creates a self-generated magnetic field (SGMF) that may be used as an electromagnet without wires.
Abstract:
An electron emitting device includes a lower electrode, a surface electrode, an electron acceleration layer between the lower electrode and the surface electrode, and an electrode selecting unit. The electron acceleration layer is made of at least an insulating material. At least one of the lower electrode and the surface electrode is a stripe-pattern electrode including a plurality of unit electrodes that are regularly arranged. The electrode selecting unit sequentially selects, from among the plurality of unit electrodes, a unit electrode to which a voltage is to be applied. A voltage is applied between the lower electrode and the surface electrode to accelerate electrons between the lower electrode and the surface electrode, so that the electrons are emitted from the surface electrode.
Abstract:
A method for fabricating a semiconductor-based planar micro-tube discharger structure is provided, including the steps of forming on a substrate two patterned electrodes separated by a gap and at least one separating block arranged in the gap, forming an insulating layer over the patterned electrodes and the separating block, and filling the insulating layer into the gap. At least two discharge paths are formed. The method can fabricate a plurality of discharge paths in a semiconductor structure, the structure having very high reliability and reusability.
Abstract:
An arc tube light source supported by a discontinuous two-part (top and bottom) frame inside a bulb of an HID lamp is ruggedized to reduce weld breakage under vibration and shock. Each of the top and bottom frames is substantially U-shaped, with the open end of the U-shape being attached by a strap to a pinch of the arc tube. For ruggedization a bracing strap is fixed to, and extends between, two sides of the frame and is welded to a lead wire extending from the pinch. Strength is enhanced if two lead wires extend from the pinch, and the bracing strap is welded to both. Advantageously the two lead wires are sides of a U-shaped wire such as a “U-pin”. Further stabilization may be achieved by using braces attached to both of the top and bottom frames and extended out against surrounding parts of the bulb.
Abstract:
A method is provided for producing a wire or tape, especially for use as an electrode or electrode tip in spark plugs. The method includes the following steps: (a) producing an intermetallic compound having a melting point above 1700° C.; (b) grinding the intermetallic compound; (c) mixing the intermetallic compound with metal powder; (d) introducing the mixture obtained in step (c) in a tube produced from ductile material; and (e) shaping the tube filled in step (d) to give a wire or tape. Also provided are a wrapped wire or wrapped tape, especially a semifinished product for producing electrodes or electrode tips of spark plugs.
Abstract:
The filament clamp assembly has a pair of bifurcated clamps to hold the connecting leads of a filament within a cavity of a cathode of a separate cathode assembly. The filament clamp assembly is mounted on the insulator block in self-aligning relation. The cathode assembly has a tungsten cathode with an internal cavity to receive the filament that is secured within a retainer shield made of one of tungsten, molybdenum and graphite by a threaded graphite cylindrical collar.
Abstract:
A fluorescent display tube, which has short-length filaments, can be driven by applied voltage of 3-8V to be used for a general fluorescent display tube. The fluorescent display tube can emit sufficient thermal electrons even if the number of filament cathodes is decreased to reduce power consumption of the filaments. The filament cathode is arranged between a first and third supporting plates by one end thereof fixed to the first supporting plate and the other end thereof fixed to the third supporting plate, and the filament cathode having an equal length with the filament cathode extended between the first and third supporting plates is arranged between the second and third supporting plates.
Abstract:
The invention relates to a discharge lamp, in particular a high-pressure discharge lamp, having a discharge vessel (1) which has two diametrically opposite necks (2, 3) into each of which a holding rod (5, 10) is fused at least in places, with an electrode (4, 9) which extends into the discharge vessel (1) being arranged on each holding rod (5, 10), and with in each case at least one annular plate (7, 12) at least partially clasping a holding rod (5, 10), with at least one of the annular plates (7, 12) being arranged in the discharge vessel (1).
Abstract:
A fluorescent lamp includes an external electrode and an internal electrode provided at opposite ends of a fluorescent tube. A power conductor may connect to the internal electrode extend outside the tube to provide a connection point for the internal electrode. The tube may include an internal support element at a first end of the tube and a substantially self supporting second end of the tube. A method for assembling a backlight includes obtaining a fluorescent lamp with an external electrode at a first end of a tube, an internal electrode at a second end of the tube opposite the first end, and an internal support element at the second end of the tube. The first end of the tube may be substantially self supporting. The method also connects first and second drive connectors to the first and second ends of the tube.
