摘要： An electron feeder for a flat-type luminous device capable of providing electrons sufficient to ensure the uniform luminance of a whole display section irrespective of a distance from an electron source. A plurality of front electrodes and a plurality of rear electrodes constituting an electron beam guide are arranged separate from one another in the direction of traveling of the electrons, respectively, and the front electrode and rear electrode corresponding to each other constitute each guide electrode section. The so-constructed guide electrode sections are alternately applied thereto two different voltages, resulting in the electron beam guide exhibiting the function of focusing electrons.

摘要： An electron feed structure for a flat-type luminous device capable of permitting electron emitted from an electrons source to be uniformly fed throughout a display section. The electron feed structure includes an electron flow guide constituted by an inner guide electrode of a high voltage and an outer guide electrode of a low voltage, so that an electric field of a high voltage and that of a low voltage may be alternately formed to form electrostatic lenses in the guide, to thereby effectively prevent the function of the electron flow guide from being deteriorated. A guide voltage applied to each of the electrode segments of the inner guide electrode is rendered constant and a guide voltage applied to each of the electrode segments of the outer guide electrode is likewise rendered constant, to thereby cause the correlation between the guide voltage and a deflection voltage applied to the electron flow guide to be uniform irrespective of a position within the electron flow guide, resulting in electrons emitted from the electron source being drawn out under the same conditions.

摘要： A field emission cathode capable of reducing an operation voltage and substantially preventing damage of an emitter. An emitter is provided on a substrate. The emitter includes a base and a plurality of rectangular tips projecting from the base. A gate is arranged in a recess formed on the substrate so as to be in proximity to the emitter. A width a of the tips of the emitter and an interval b between the tips are defined to satisfy a relationship of b/a=2. This permits an electric field strength applied to the tips of the emitter to be substantially increased as compared in a conventional field emission cathode of b/a.ltoreq.1, resulting in an operation voltage being reduced and a sufficient amount of emitter current being produced.

摘要： A vacuum envelope that can improve the vacuum degree in a field emission device is provided. The vacuum envelope includes the cathode side substrate 2 on which field emission elements are formed and the anode substrate 1 spaced by a predetermined distance in the electron emission direction. At least two openings are formed before sealing the vacuum envelope. The remaining gas is ousted from the vacuum envelope by introducing a high temperature gas inside the vacuum envelope for a predetermined period of time. Thereafter, one of the openings is sealed while the envelope is being evacuated to a vacuum state through the remaining openings.

摘要： A method for manufacturing a display device is available that is capable of remarkably improving life characteristics of a display device. A display device placed in a chamber is evacuated to about 10.sup.-7 Torr. Then, reducing gas is introduced into the display device and held therein for several minutes, followed by evacuation of the display device to about 10.sup.-5 Torr. The reducing gas introducing and discharge steps are repeated several times. Thereafter, evacuation of the display device is carried out while keeping the chamber at about 300.degree. C., followed by sealing of the display device.

摘要： An evacuation apparatus is capable of evacuating an envelope to a high vacuum without evacuating a whole room or chamber to a high vacuum. An evacuation pipe is connected at a distal end thereof to an evacuation head and a vacuum pump is actuated to evacuate an evacuation chamber to a high vacuum, to thereby evacuate an envelope to a high vacuum. Then, a motor is driven to rotate ball screws, to thereby upwardly move the envelope mounted on the evacuation head. The evacuation pipe is fused at an intermediate portion thereof by a gas burner, to thereby be sealed. Then, the evacuation pipe is cut to disconnect the envelope from the evacuation head.
