    Abstract: The present invention relates to a method of and a vertical pumping device (1) for internally distributing Hg in a fluorescent tube body (3). The bottom (7) of the fluorescent tube body (3) is closed. The device (1) arranges, in a first position, a first solid body (9?) comprising a predetermined first amount of bound Hg. The device (1) arranges, in a second position, a second solid body (9?) comprising a predetermined second amount of bound Hg. A first release (E1) of the first amount of Hg is achieved in the fluorescent tube body (3) by gasification with heat and under pressure for purification of contaminant particles in the fluorescent tube body. A second release (E2) of the second amount of Hg is achieved in the fluorescent tube body (3) by gasification attained for the occluded mercury vapour of the fluorescent tube body (3).

  • Publication number: 20130307404
    Abstract: With respect to a vacuum tube having a reduced pressure vessel containing an electric discharge gas sealed therein, problems such as the lowering of discharge efficiency owing to an organic material, moisture or oxygen remaining in the reduced pressure vessel have taken place conventionally. It has been now found that the selection of the number of water molecules, the number of molecules of an organic gas and the number of oxygen molecules remaining in the reduced pressure vessel, in a relation with the number of molecules of a gas contributing the electric discharge allows the reduction of the adverse effect by the above-mentioned remaining gas. Specifically, the selection of the number of molecules of the above electric discharge gas being about ten times that of the above-mentioned remaining gas or more can reduce the adverse effect by the above-mentioned remaining gas.

  • Publication number: 20030087579
    Abstract: A suction device used in aging process of a microwave tube includes an ion pump and a suction unit respectively connected to an electron gun and a collector located in two opposite ends of the microwave tube. The suction unit includes a barrel communicated with the microwave tube and a getter disposed in the barrel. An electric power source is electrically connected to the getter. Before operation, the microwave tube along with the suction device undergo exhaust process on a heating exhaust station. After that, the electric power source supplies an electric current to electrify and heat the getter to its activation condition. Therefore, the suction device can greatly save the vacuum suction time of the aging process and the cost associated with the production of the microwave tube.

  • Publication number: 20020187713
    Abstract: During the manufacture of CRT's a manufacturing step requires that a vacuum be drawn on all CRT's while baking in an exhaust oven. This process is usually performed simultaneously on a plurality of CRT's connected to an exhaust cart by a manifold. The present invention provides a method and apparatus to reduce processing times by utilizing a roughing pump and diffusion pump to alternately evacuate a CRT being processed while isolated from one another. The methodology allows the diffusion pump to remain at a high vacuum level at all times therefore eliminating the need for lengthy warm up of the diffusion pump each time a CRT is processed.

  • Patent number: 6443789
    Abstract: A device (10) for introducing hydrogen into a flat display (14) of the field emission or plasma addressed liquid crystal type is described, formed of a reservoir (11) containing a hydrogen accumulator material (21) connected to the internal space (13) of the display by means of a wall (15) permeable to the passage of hydrogen gas as a function of the temperature. The device comprises a heater (19) and a heater (22) for bringing respectively the wall and the accumulator material to the desired temperatures, or a single heater which carries out both cited functions. There is also described a method by which the device is activated whenever the flat display is working, the switching on of said heater being arranged in order to bring the wall itself to a previously calculated temperature.

  • Patent number: 6304029
    Abstract: A method of manufacturing a low-pressure mercury vapor discharge lamp starting from a discharge vessel (10) wherein a closed holder (22) is placed which is provided with a quantity of one or more substances to be introduced in the discharge vessel (10). Subsequently, a desired gas atmosphere is brought about in the discharge vessel (10) and the discharge vessel is closed. Finally, the holder (22) is opened. According to the invention, the holder (22) is made from a leadoxide containing glass, which leadoxide is partly reduced and in which the amount of reduction is a measure of the mercury content of the holder (22). Due to the reduction process holders (22) with different mercury contents have a different color.
