摘要： A method of manufacturing an arc tube having a light emitting tube portion, a first pinch seal portion, and a second pinch seal portion, all formed on a quartz glass tube. The first and second pinch seal portions are disposed on both sides of the light emitting tube portion. The quartz glass is provided almost vertically with the first pinch seal portion down. A thermal insulating plate is provided in a boundary position between the light emitting tube portion and a portion to be pinch-sealed in an outer peripheral space of the quartz glass tube. Liquid nitrogen is jetted from a cooling nozzle provided obliquely below the light emitting tube portion toward the same, thereby cooling the light emitting tube portion. The portion to be pinch-sealed is heated with a burner, and pinch-sealed with a pincher immediately thereafter.

摘要： An arc tube provided with a central sealed chamber 12, in which light-emitting substances are enclosed, having a pair of electrode assemblies disposed opposite to each other. The electrode assemblies are sealed in pinch seal portions 13. The arc tube incorporates a residual-compressive-stress layer 16 formed on a surface of the glass layer 15 in each of the pinch seal portions 13 that contacts the electrode rod 6 included in each electrode assembly. The residual-compressive-stress layer has a length greater than or equal to 30% of the axial length of a glass layer region that only contacts the electrode rod 6 and/or an angular range greater than or equal to 180° in a circumferential direction of the electrode rod. Thermal stress (tensile stress) produced in the boundary between the glass layer 15 and the electrode rods 6 after the arc tube 10 has been turned on is absorbed and dispersed by the residual-compressive-stress layer 16 surrounding the electrode rods 6. Thus, any vertical crack that would result in the light-emitting substances leaking from the sealed chamber does not form in the glass layer 15 of the pinch seal portions 13.

摘要： A method of manufacturing an arc tube for a discharge lamp unit, incorporating a primary pinch-sealing step for mounting an electrode assembly in an open end of a glass tube W with a chamber portion 12. The electrode assembly comprises an electrode rod 6, a connecting foil 7 and a lead wire 8 integrally connected in series. The electrode assembly is inserted into an open end of the glass tube W such that a leading end of the electrode rod projects into the chamber portion 12. A temporary pinch seal region L1 of the glass tube W is pinch-sealed such that a portion of the connecting foil that is connected to the lead wire is contacted by the glass tube W. A vacuum is maintained inside the glass tube and a main pinch seal region L2 of the glass tube is pinch-sealed such that a portion of the connecting foil connected to the electrode rod is contacted by the glass tube. When the main pinch seal region L2 of glass tube W is pinch-sealed, the negative pressure in the glass tube W is exerted on the softened sealed chamber portion 12 owing to supplied heat as well as the pressure exerted from the pincher 26b. Thus, the glass layer 15 is pressed against the surface of the molybdenum foil 7 so that hermetic contact is realized.

摘要： The pinch-sealing for the first one of a pair of molybdenum foils is not performed by flowing inactive gas within a quartz glass tube like the prior art but performed in a manner that the lower end portion of the quartz glass tube 4 is sealed, and then and a pinch seal estimation portion 4b is squeezed by a pincher while air within the quartz glass tube is exhausted from the upper end portion thereof so that pressure within the quartz glass tube becomes in a negative pressure state of 100 torr or less and while heating the pinch seal estimation portion 4b. Accordingly, at the time of the squeezing, the inner wall surface 4c of the pinch seal estimation portion 4b thus heated is attracted to the molybdenum foil 12 side thereby to form fine concave and convex portions on the interfaces between the molybdenum foil 12 and the quartz glass tube 4, so that the molybdenum foil and the quartz glass tube are placed in an engaged state and the contact area therebetween is increased.
摘要翻译：一对钼箔中的第一个的夹紧不是通过在现有技术的石英玻璃管内流动惰性气体而是以石英玻璃管4的下端密封的方式进行的，然后通过夹持器挤压密封估计部分4b，同时石英玻璃管内的空气从其上端部排出，使得石英玻璃管内的压力变为100托或更低的负压状态夹紧密封估计部分4b。因此，在挤压时，如此加热的夹送密封估计部4b的内壁面4c被吸引到钼箔12侧，从而在钼箔12和石英之间的界面上形成微细的凹凸部玻璃管4，使得钼箔和石英玻璃管处于接合状态，并且其间的接触面积增加。

摘要： An arc tube that effectively prevents a metal halide from being deposited in a light emitting tube portion, causing the change of a light emitting color or the generation of lighting failures in an arc tube. An axial distance L1 from a neck portion 20C of an arc tube body formed between a light emitting tube portion 20A and a pinch seal portion 24B of the arc tube body to a step-down plane portion 20Ba2 of each pinch seal surface 20Ba in a pinch seal portion 20B is set to 1 mm or less. During pinch seal, consequently, a sufficient pinching pressure is applied to a electrode 26, such as a tungsten electrode up to a portion close to a tip portion thereof. Thus, it is possible to reduce the volume of an almost wedge-shaped slit 24a formed around the tungsten electrode 26 on an end in the axial direction of a discharge space 24, thereby decreasing the amount of a metal halide deposited on the slit 24a.
摘要翻译：一种电弧管，其有效地防止金属卤化物沉积在发光管部分中，导致发光颜色的变化或电弧管中的发光故障的产生。与电弧的颈部20C的轴向距离L1 在发光管部20A和发光管体的压紧密封部24B之间形成的管体与夹紧密封部20B中的每个夹紧密封面20Ba的降压面部20Ba2的距离设定为1mm以下。因此，在夹紧密封期间，向电极26（例如钨电极）施加足够的夹持压力，直到其末端部分附近的部分。因此，可以减小在放电空间24的轴向端部上形成的钨电极26周围的几乎楔形的狭缝24a的体积，从而减少沉积在狭缝24a上的金属卤化物的量。

摘要： An arc tube body 20 and a foil such as molybdenum foil 30 are joined with each other such that a compressive stress of 105 N/m2 or more remains at an ordinary temperature in the arc tube body 20 along a junction surface. The compressive stress is always generated on the arc tube body 20 even if a fluctuation in the stress is caused on the junction surface by the repetition of the ON/OFF of the arc tube (or a tensile stress is caused to have a very small value even if the compressive stress and the tensile stress are alternately generated). Thus, the junction strength of both members may be increased. In one embodiment, a plurality of cracks (intercrystalline cracks) may be generated on the molybdenum foil 30 by a high pressure acting during pinch seal, and quartz glass is caused to enter the cracks so that the junction strength of both members can be increased.
摘要翻译：电弧管体20和诸如钼箔30的箔彼此接合，使得10 5 N / m 2以上的压缩应力保持在普通电弧管主体20沿着接合面的温度。即使通过重复发光管的接通/断开而在接合面上产生应力波动（或拉伸应力具有非常小的值），也始终在电弧管主体20上产生压缩应力即使压缩应力和拉伸应力交替地产生）。因此，可以增加两个部件的接合强度。在一个实施例中，可以通过在夹紧密封期间作用的高压在钼箔30上产生多个裂纹（晶间裂纹），并且使石英玻璃进入裂纹，从而可以增加两个部件的结合强度。
