Abstract: A cold cathode electronic device capable of removing pollution of emitter electrodes occurring during manufacturing of the device, to thereby enhance emission characteristics of the emitter electrodes and luminous efficiency of a phosphor layer. The cold cathode electronic device includes hydrogen occlusion metal incorporated in a gate electrode and/or an anode electrode. A field emission luminous device and a cold cathode luminous device each including such a cold cathode electronic device are disclosed.

Abstract: 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.

Abstract: 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.

Abstract: 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).
