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： A discharge lamp has a lamp assembly including a discharge lamp unit with a pair of lamp leads extending therefrom, and a base assembly including a pair of base leads electrically connected to the pair of lamp leads and mechanically supporting the lamp unit in position with respect to the base assembly. The base assembly comprises a hollow base structure of electrically insulating material molded in one piece with a partition dividing the interior thereof into a pair of completely isolated spaces. Electrically connected to the base leads, a pair of sheet metal conductors are received with clearances in the respective isolated spaces in order to preclude the possibility of an electric discharge taking place between the pair of conductors within the base structure.

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： 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。
