摘要:
A method for manufacturing a glass container and an apparatus therefor capable of providing the container by pressing of a glass substrate using a die while keeping the glass substrate uniformly heated and softened. The glass substrate is heated while being kept lifted from a lower mold of a forming die and then subject to integral forming by the forming die. This permits the glass substrate to be integrally formed into the glass container in the form of a finished product, resulting in the number of steps and time required for processing being reduced.

A fluorescent display device (1) includes an air tight envelope (2) having a cathode substrate (3), an anode substrate (4) with a phosphor layer arranged to provide a luminous display, a seal member (5), an evacuation hole (9) formed at a side of the envelope (2), and a getter chamber (10) in communication with the hole (9). The getter chamber (10) is disposed on the outside of the envelope (2) and includes a chamber body (12), and an evacuation tube (13). The getter chamber (10) eliminates the independent formation of an evacuation hole in the cathode substrate (3), and thereby prevents damage and contamination of the cathode substrate (3).
摘要:
A fluorescent display device capable of being sealed while being evacuated to a high vacuum without independently forming any evacuation hole at an electrode formation section of a substrate of an envelope. A cathode substrate is sealedly formed of an electrode formation section of a large plate-like shape provided thereon with a field emission cathode, an evacuation section of a small plate-like shape formed with a cutout, and a seal member. An anode substrate on which a display section is spacedly arranged oppositely to the cathode substrate. A getter chamber including an evacuation tube is connected to the evacuation hole. Thus, the present invention eliminate independent formation of any specific evacuation at the electrode formation section, to thereby prevent damage and contamination of the substrates.

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 vacuum container capable of arranging a getter member therein while preventing an increase in overall height of an envelope and therefore the vacuum container. An anode substrate on which anode electrodes providing a display section are formed and a cathode substrate on which field emission cathodes are formed are arranged opposite to each other and sealedly joined to each other through an outer periphery thereof, to thereby provide an envelope. The cathode substrate is formed with a through-hole communicating with an interior of the envelope. The through-hole has a getter member received therein. The cathode substrate is provided on a portion of an outer surface thereof at which the through-hole is formed with an evacuation pipe through which the envelope is evacuated.
摘要:
A getter support capable of permitting a getter to be compactly arranged in a vacuum envelope while keeping a space for the getter minimized. The getter support includes holders for vertically interposedly holding a getter, first support legs formed integrally with the holders so as to downwardly extend therefrom, and second support legs formed integrally with the holders so as to upwardly extend therefrom. The getter support is fixedly arranged in a getter chamber while being pressed by elasticity of the second support legs. The second support legs are varied in deflection depending on contact thereof with a second substrate of an envelope. This permits a distance between an upper surface of the getter and the second substrate of the envelope to be constantly kept at a desired value.

A casing for a display device of the tipless type is disclosed which is capable of being readily manufactured, and allowing a display device to have a good space factor and exhibit excellent display characteristics. The casing comprises a casing body formed with an evacuation hole and a planar plate lid member arranged to sealingly close the evacuation hole by means of a sealer when the casing is evacuated.
摘要:
An X-ray generator comprises a container (1) for maintaining a high vacuum or low pressure gas atmosphere internally, a hemimorphic crystal (4), temperature raising/lowering means (3, 5-7), and a metal target (8) for generating X-rays. In this X-ray generator the metal target (8) has a pointed protrusion protruding toward the hemimorphic crystal (4). When X-rays are generated by raising/lowering the temperature of the hemimorphic crystal (4) by using the temperature raising/lowering means (3, 5-7), the intensity of an electric field formed between the hemimorphic crystal (4) and the metal target (8) increases at the pointed end of the protrusion and thus the intensity of X-rays generated through collision of electrons against the metal target (8) increases. Consequently, an X-ray generator employing a hemimorphic crystal, which is capable of generating X-rays with practically sufficient intensity can be provided.
摘要:
Electron excited luminous element capable of ensuring satisfactory emission characteristics of emitters for an extended period of time. A hydrophobic insulating film is formed on a glass anode substrate so as to cover an exposed portion thereof between anode electrodes. This keeps the glass anode substrate from being directly attacked by electrons, to thereby prevent decomposition of water and the like contained in a surface of the glass, resulting in oxygen which causes deterioration in emission characteristics of emitter cones being kept from being released from the glass.
