    • A flat type indicator tube is provided with a box-like cover glass on a substrate. The cover glass forms an air tight space together with the substrate. In the space, there are provided display sections each consisting of a plurality of anode segments disposed on the substrate, grid and cathode electrodes provided above the display sections. The cover glass is comprised of a flat major section, a side wall and a flange section. The flange section comprises a flat flange contacting the substrate through glass frit and a coupling portion so shaped as to receive one end portion of the exhaust tube therein. A projection is formed on and substantially perpendicular to the inner wall of the coupling portion of the flange section. The projection is contacted and serves to restrict undesired excessive insertion of the exhaust tube into the coupling portion. The exhaust tube is hermetically fixed between the coupling portion and the substrate through glass frit.
    • 扁平型指示管在基板上设置有盒状的盖玻片。 覆盖玻璃与基底一起形成气密的空间。 在该空间中,设置有显示部分,每个显示部分包括设置在基板上的多个阳极部分,设置在显示部分上方的栅极和阴极电极。 盖玻璃由平坦的主要部分,侧壁和凸缘部分组成。 凸缘部分包括通过玻璃料接触基板的平坦凸缘和成形为在其中容纳排气管的一个端部的联接部分。 凸缘形成在凸缘部分的联接部分的内壁上并且基本上垂直于凸缘部分的联接部分的内壁。 突起接触并且用于限制排气管不期望地过度插入联接部分中。 排气管通过玻璃料气密地固定在连接部分和基底之间。

    • An amalgam is accurately placed and retained in an optimized location in the exhaust tube of an electrodeless SEF lamp for operation at a mercury vapor pressure in the optimum range from approximately four to seven millitorr by forming a dimple in the exhaust tube and using a dose locating member to locate and retain the amalgam on the side of the dimple away from the core of the lamp after filling the lamp. As an alternative, two dimples may be situated on opposite sides of the exhaust tube for performing the same function as, but with less depth than, the single dimple. In another alternative embodiment, first and second dimple configurations are formed in the exhaust tube after tip-off thereof, each dimple configuration including either one or two dimples. The second dimple configuration is spaced apart from the first dimple configuration along the length of the exhaust tube. In this way, the amalgam may be initially positioned farther from the tip-off region, thereby avoiding problems during tipping off of the exhaust tube, such as loss of mercury from the lamp, or quenching of the tip which could cause stress cracks. After tip-off, the second dimple configuration allows for placement of the amalgam closer to, or preferably in contact with, the tip of the sealed exhaust tube, i.e., the coolest location in the exhaust tube.
    • 汞齐被精确地放置并保持在无电极SEF灯的排气管中的优化位置,以在约4至7毫托的最佳范围内的汞蒸汽压力下操作,通过在排气管中形成凹坑并使用剂量定位 成员在填充灯泡之后,将灯泡的灯头侧面的汞齐定位并保持在远离灯芯的位置。 作为替代方案,两个凹坑可以位于排气管的相对侧上,用于执行与单个凹坑相同的功能,但具有较小的深度。 在另一替代实施例中,第一和第二凹坑配置在其脱开之后形成在排气管中,每个凹坑配置包括一个或两个凹坑。 第二凹坑配置沿着排气管的长度与第一凹坑配置间隔开。 以这种方式,汞齐可以最初位于距脱落区域更远的地方,从而避免了在排出管的脱落过程中的问题,例如灯的汞损失,或尖端的淬火,这可能引起应力裂纹。 在脱落之后,第二凹坑配置允许将汞合金放置在密封排气管的末端(即排气管中的最冷的位置)上,或优选地与其接触。
