Abstract: The present invention is to provide a gas discharge tube which is properly lighted to improve the reproducibility of a satisfactory light emission state. The gas discharge tube includes an envelop (11) for accommodating a hot cathode (25) for emitting thermoelectrons, an anode (24) for receiving the thermoelectrons, a focusing electrode (26) having a focusing opening for converging paths of the thermoelectrons, and a discharge shielding member (21) supporting the focusing electrode and the anode, the discharge shielding member further supporting a cathode box for surrounding the hot cathode while electrically insulated from the focusing electrode. And since a lighting device for the gas discharge tube sets the focusing electrode a zero or negative potential while an electric field generated between the hot cathode and the anode, the lighting device will be certainly turn on.

Abstract: In the gas discharge tube of the present invention, for elongating the life of the discharge tube 1 itself while lowering the assembling temperature, a side tube 14 itself is formed from glass, and a metal is employed in a joint between a stem 4 and the side tube 14. Namely, a metal-made first peripheral portion 15 provided in the stem 4 and a metal-made second peripheral portion 16 provided in the side tube 14 are utilized in the joint. As a result, the discharge tube 1 itself can be made smaller.

Abstract: In a gas discharge tube 1 in accordance with the present invention, one or both of the inner wall face 22A and outer wall face 22B of a side tube body 22 are provided with a coating 21 made of a glass material or ceramics. As a result, the side tube body 22 can be made of various materials regardless of properties of the gas filling the inside, whereby the gas discharge tube 1 can have a wider range of processed forms and smaller dimensions at the same time, and its mass production can freely be carried out.

Abstract: A gas discharge tube comprises an envelope (11) for sealing a gas, lead pins (13-16) and a light-emitting assembly (20). The light-emitting assembly includes: a focusing electrode support member (21) of a conductive material; a hot cathode (31) for emitting thermoelectrons; an anode (24) for receiving thermoelectrons; a focusing electrode (29) for converging paths of thermoelectrons; a first spacer (50a) of an insulator being arranged between the focusing electrode support member and the anode; a second spacer (50b) of an insulator being arranged at an opposite side to the first spacer through the anode; and an anode support member (22) of a conductive material for pushing the anode onto the focusing electrode support member through the first and second spacers. A gas discharge tube having a long service life and capable of improving the operational stability during long-time continuous light emission can be provided.

Abstract: A gas discharge tube of the present invention comprises a light-emitting section (2) in an envelope (1) sealing a gas therein, positioned at distal ends of lead pins (4a to 4e) and supported by the lead pins while spaced from an inner side wall of the envelope. The light-emitting section includes a hot cathode (7), an anode (8), a focusing electrode (13), and a discharge shielding member (6) having a front surface which faces to the hot cathode. The front surface of the discharge shielding member is defined by a first surface being in directly contact with the focusing electrode, for defining a position of said focusing electrode, a second surface continued from the first surface, for defining a distance between the focusing electrode and the anode, and a third surface continued from the second surface and being in directly contact with the anode, for defining a position of the anode.

Abstract: In a gas discharge tube 1 in accordance with the present invention, a side tube 22 is formed from a metal, the outer periphery of the stem 4 is provided with a joint portion 15b made of a metal, and the latter is joined to a metal-made joint portion 16 of the side tube 22 by welding, whereby the assembling is made easier by welding, while the gas discharge tube 1 itself can attain smaller dimensions. Also, since the side tube 22 is small and made of a metal, its handling improves greatly. Further, since side tube 22 is formed from a metal, the gas discharge tube 1 is encouraged to have a wider range of processed forms and attains a prospect for mass production.
