    Abstract: A high pressure discharge lamp comprises a vessel made of a non-conductive material which forms an inner space filled with an ionizable light-emitting material and a starting gas. The vessel has an opening portion at one end thereof. A tubular member is arranged at the opening portion of the vessel and has an outer diameter which is substantially the same as an inner diameter of the first opening portion. An electrode unit is inserted into the tubular member and has an outer diameter which is smaller than an inner diameter of the tubular member. A stopper is arranged between the tubular member and the electrode unit and has an outer diameter which is substantially the same as the inner diameter of the tubular member. The stopper has a hole into which the electrode unit is inserted. A frit seal is filled in a gap which is formed by the tubular member, the stopper and the electrode unit. The stopper defines an inner end position of the frit seal in the tubular member.

    Abstract: A light emitting element comprises a housing (34) formed by allowing respective first principal surfaces of a rectangular upper housing member (12) made of glass material and having a recess at a central portion on its first principal surface and a rectangular lower housing member (14) made of glass material and having a recess at a central portion on its first principal surface as well to make contact with each other so that they are thermally glued by press under a pressure in a predetermined atmosphere; a cavity (16) formed by the respective recesses (30, 32) in the housing (34) and enclosed with at least one of a gas and a light emitting substance; and two lead wires (18, 20) confronted with each other with the cavity (16) interposed therebetween. Accordingly, it is possible to simultaneously realize the integration and the miniaturization of the electronic tube and present the display expression for information transmission at a high brightness.

    Abstract: A process to produce a ceramic tube for a metallic halide lamp, comprising the steps of forming an integrally molded body (1) composed of an electrode member-inserting portion (1a) and an annular portion (1b) located around an outer periphery of the electrode member-inserting portion, inserting the annular portion of the integrally molded body into an open end portion of a molded cylindrical tubular body (3) in a state that each of the integrally molded body and the molded tubular body is used as molded or after being calcined, thereby forming an assembled body, and firing the assembled body, thereby forming an integrally fired body composed of the electrode member-inserting portion and the annular portion. The annular portion and the tubular body are sintered to each other by firing in a state that radial press fitting forces act between the annular portion and the tubular body.

    Abstract: To prevent occurrence of cracks without employing such a method as the precision control of sealing frit or the increase of capillary thickness. As a means for solution, about 20 times as much magnesium oxide as for a barrel portion (2) having an arcing space was added to form a capillary (3), followed by calcination at 1,200 DEG C. And after it had been connected to the separately formed barrel portion (2), the assembly was calcined again at 1,200 DEG C, and fired in a hydrogen atmosphere at 1,850 DEG C for 3 hours, with the result that whereas the mean alumina particle size for the barrel portion (2) was 32 mu m, the mean particle size for the capillary (3) was 19 mu m, giving an increase in strength.

    Abstract translation: 本发明的目的是防止在玻璃料封口机上产生裂纹，而不需要确定玻璃料密封剂的精确量并增加每个毛细管的壁厚。 为了实现该目的，毛细管3由掺杂有一定数量的氧化镁的材料形成，该氧化镁比其中设置有发光空间的中心体2的材料大20倍，然后在1200℃预烘烤。 毛细管3连接到主体2，并且都在1200℃再次烘烤。最后，两者都在氢气气氛下在1850℃下烘烤3小时。 结果，毛细管3中的氧化铝颗粒的平均直径为19微米，小于中心体2的32微米，因此增加毛细管3的体力。
