Abstract: A mercury supplying method capable of always supplying a constant amount of mercury into a chamber part easily by executing measurement and ejection of the mercury at the same time. A small diameter pipe as a mercury supply path, is inserted through a glass tube elongating from a chamber part of an arc tube from above so as to have the tip part thereof substantially reaching into the chamber part, and connecting the upstream side of the sealed mercury supply path (mercury barrel) with a gas pressure adjuster. The gas pressure adjuster keeps the inside of the mercury supply path (mercury barrel) at a predetermined pressure so as to maintain the inside of the small diameter pipe in the state filled with mercury as well as applying a predetermined pressure to the mercury in the small diameter pipe for a predetermined time and thus ejecting a predetermined amount of mercury from the small diameter pipe tip part so as to be dropped and supplied to the chamber part. Measurement and ejection of the mercury can be executed at the same time with the small diameter pipe inserted through the glass tube of the arc tube from above. A predetermined amount of mercury can always be supplied into the chamber part in a short time.

Abstract: An arc tube and method of fabricating the arc tube for a discharge lamp. The arc tube includes an arc tube main body 10 at which a sealed glass bulb 12 serving as a discharge portion sandwiched by pinch seal portions is formed at a portion of a glass tube W along the longitudinal direction thereof, and a cylindrical shroud glass 20 which is welded on and integrated with the arc tube main body 10 so as to cover the sealed glass bulb 12, the front and rear end portions of the shroud glass 20 may be joined, for example, by welding on shroud glass welded portions with circular cross sections provided at the front and rear end sides of the arc tube main body 10, respectively. The inner peripheral surface of the diameter reduced portion of the shroud glass tube 20, which is molten, soften and deformed inside along the radial direction, contacts closely to the circular outer peripheral surface on the arc tube main body 10 side, so that a space can not be formed at the welding portion of the shroud glass 20 (adhesion surface). Thus, the atmosphere does not enter into the sealed space 24 surrounded by the shroud glass 20, and accordingly, devitrification is prevented.

Abstract: In the manufacture of arc tubes for use as light sources of vehicle headlamps, there is first prepared a semifinished arc tube by inserting one electrode assembly into a tubular glass envelope through one end thereof and by sealing this end. The semifinished arc tube is then placed in communication with a hermetically enclosed space filled with argon under pressure, with the consequent introduction of the inert gas into the glass envelope through a second end thereof. Another electrode assembly and chemicals such as a metal halide and mercury are then introduced from the enclosed space into the semifinished arc tube through the second end, totally without contact with the atmospheric air. Then, with the glass envelope placed out of communication with the enclosed space, the argon is exhausted from within the envelope, and xenon is charged instead into the envelope through the second end, which is closed subsequently.

Abstract: An arc tube having a closed glass bulb having no broken-off portion, and a method of manufacturing the arc tube. A glass bulb is formed on a glass tube substantially at the middle. An electrode assembly is inserted into one end portion of the glass tube, and the one end portion is closed by pinch-sealing. A light emitting material is supplied into the glass bulb through the other end portion of the glass tube, another electrode assembly is inserted into the other end portion, and the latter is closed by pinch-sealing. Since the closed glass bulb has no broken-off portion, the arc tube is free from the difficulty that the distribution of light is adversely affected. Moreover, in manufacturing the arc tube of the invention, it is unnecessary to connect an exhaust tube to the glass tube. Therefore, the number of manufacturing steps is small, and the arc tube can be manufactured with ease.

Abstract: Before an electrode assembly is inserted into a quartz glass tube, a reinforcement bending process is applied to a metal foil. Even when a vibration load acts on the electrode assembly during the insertion of the electrode assembly into the quartz glass tube, the metal foil is not easily deformed, so that a rod electrode can be prevented from largely swinging together with the metal foil. Consequently, the position of a tip end portion of the rod electrode can be easily recognized by using a camera, whereby the degree of the insertion of the electrode assembly into the quartz glass tube can be correctly adjusted.

Abstract: A method of producing an arc tube including inserting an electrode assembly in which a bent portion is formed in a lead wire into a glass tube to self-hold the electrode assembly to a predetermined position of the glass tube. After the electrode has been inserted to the predetermined position, pinch-sealing is conducted on a portion of the glass tube where the assembly is inserted. In the method, the electrode assembly is inserted into a metal guide pipe which is coaxially disposed with respect to the glass tube, to be once held into the pipe. Thereafter, the assembly may be pushed by a thin rod-like pushing member to be inserted to the predetermined position in the glass tube. One or more vertical grooves which are to be axially engaged with the bent portion of the assembly to circumferentially lock the bent portion may be formed in the inner side of the guide pipe. Using the one or more grooves, the assembly may be guided to the glass tube W without being in sliding contact with the guide pipe. Therefore, in a preferable embodiment, this prevents metal powder, which may be produced by rubbing and shaving the inner side of the guide pipe with the bent portion of the lead wire, from entering the chamber portion as a foreign matter. A holding chuck is not required to insert the assembly into the glass tube, but is used to facilitate insertion of the assembly into the guide pipe. The chuck for holding the assembly is not restricted in shape. The assembly in the guide pipe is guided to the glass tube and may be restricted by the vertical grooves to be circumferentially positioned.
