IPC: H05B41/24
Filed: 1988-05-17
Abstract: PURPOSE:To prevent excess power impression onto a high-frequency generating apparatus by stopping/reducing supply of lighting electric power to an electric discharge lamp when each filamentary coil output voltage, in a condition established after the lapse of time necessary until the electric discharge lamp is lit during the starting phase of the electric discharge lamp, exceeds each specified value. CONSTITUTION:When a DC voltage is fed from a DC power supply 13 to a high-frequency generating apparatus 1, a transistor 2 therein is turned on and off by means of a switching controller 4 to output a high-frequency voltage ranging from 20 to 100kHz. The resulting high-frequency voltage is fed through an output coil 3b and filamentary coils 3c, 3d to an electric discharge lamp 6 so as to cause lighting of the lamp 6. Respective output voltages generated from the output coil 3b and the filamentary coils 3c, 3d are all no-load ones and also relatively high in their power levels prior to lighting of the electric discharge lamp 6, while the voltage in the output coil 3b drops to the lamp voltage and then proportionally so do the voltages in the coils 3c, 3d posterior to the lighting. When the electric discharge lamp 6 is not lit up and the output voltage from the coil 3d is not reduced even after the lapse of a specified time, the level of power outputting from the high-frequency generating apparatus 1 is reduced so that the continuous generation of high voltages in no-load condition can be prevented.

Title: Luminous radiation electron tube
Inventor: TOHO MAKOTO
IPC: H01J63/08
Filed: 1986-05-26
Abstract: PURPOSE:To obtain a luminous radiation electron tube of a better luminous efficiency, by furnishing static magnetic field generating sources at specific positions. CONSTITUTION:The distance between an anode and a cathode is made less than the mean free path of electrons, the distance between the anode and the tube wall sufficiently larger than the mean free path of electrons, and static magnetic field generating sources are furnished near the tube wall close to the cathode and near the tube wall at the opposite side of the anode. By applying a DC voltage between the cathode 2 and the anode 3, electrons flying out of the cathode 2 are injected in a luminous space 4 at the rear space of the anode 3 while winding over the lines of magnetic force between the static field generating sources 6 and 6, repeating a reciplocation movement along the lines of magnetic force until they strike the luminous radiation gas sealed in the tube. Therefore, by converting the positions of the static magnetic field generating sources 6 and 6, the distribution of the lines of magnetic force can be converted within the luminous area. When the electrons flying out of the cathode pass on a locus l to penetrate the enclosed plane of the ring-form anode 3, for example, the energy is made fairly lower than the anode potential Va, resulting in an increased luminous efficiency making an even radiation in a desired form of tube body 1.

A lever 41 moves down in accordance with the movement of the movable iron core 2, and a projection 42a of a push button 42 is depressed by the pressing part 41a of the lever 41. When the electromagnetic coil 4 is deexcited, it returns to an original condition.
