著しく細くした場合、下記のような不都合を生じること
になる。[Problem to be Solved by the Invention] In such a conventional configuration, a mercury discharge structure used for discharging mercury into a tube such as a fluorescent discharge lamp is well known, but its configuration is a holder and a holder. , which retains mercury-releasing compounds. For example, if the tube diameter of a fluorescent discharge lamp is significantly reduced in order to miniaturize it, the following problems will occur.

るという問題を基本的に有している。First, a shape that can be placed inside a pipe with a small diameter,
For example, it is necessary to pre-process the pipe into a thin shape according to the pipe diameter, which basically poses a problem in that the number of processing steps increases and the manufacturing cost increases.
【０００８】また、上記の予備加工時に発生する水銀化
合物の脱落による封入水銀量のバラツキあるいは環境の
汚染が発生するという問題を有している。[0008] Furthermore, there is a problem in that the amount of mercury encapsulated varies or the environment is contaminated due to the dropping of mercury compounds generated during the above-mentioned preliminary processing.

うという問題を有している。[0009]Furthermore, the manufacture of fluorescent discharge lamps usually includes a high temperature application process such as a sealing process. Therefore, in the above-mentioned mercury release structure, even if the mercury compound does not fall off during processing, during the heating process to a high temperature, a part of the mercury contained inside the structure is unnecessarily released due to the high temperature applied. There is a problem.

能性は著しく高くなる。[0010] On the other hand, if mercury is released unnecessarily, a fatal problem may occur in which the specified amount of mercury cannot be released into the pipe even if the original mercury release process is carried out.
If mercury compounds are shed, the possibility of insufficient mercury release increases significantly.

Processing is required, and preliminary processing work including setting and controlling the amount of mercury becomes extremely complex and troublesome.

になる。[0012] Furthermore, in order to prevent the above-mentioned fatal problem of insufficient mercury from occurring, the shape of the mercury discharge structure becomes elongated when considering a specified mercury amount as a standard. If the mercury discharge structure is made thin and long in order to ensure a specified amount of mercury discharge, a problem arises in that the ratio of the effective light emitting length to the total length of the discharge tube becomes small.

The object of the present invention is to provide a mercury release structure capable of releasing mercury into a pipe and a method for manufacturing the same.

Therefore, there is no need for preliminary processing such as bending and cutting to install the mercury release structure in a pipe, which was necessary in the conventional structure. Furthermore, since the structure does not use a cage to hold the mercury-releasing compound, it is advantageous in terms of volume compared to a structure with a cage.Furthermore, by controlling the shape and size of the sintered body, In other words, the amount of mercury that can be released into the pipe can be easily controlled.

As shown in FIG. 2(a), one or more types of metal powder 2 such as titanium, zirconium, tantalum, and nickel is prepared, and then this metal powder 2 is applied to the diameter of the discharge tube to be used or as required. A first step is performed in which the metal sintered body 3 is sintered into an optimal shape, for example, a cylindrical shape, taking into account the amount of mercury and the like.

Steps 2 to 4 are performed to combine mercury with mercury. That is, as shown in FIG. 2(b), there is a second step in which the metal sintered body 3 is placed in the heating container 5 together with mercury 4, and a third step in which the inside of the heating container 5 is made into a vacuum atmosphere using the vacuum pump 6.

第２工程を行うようにしても良い。In this embodiment, the metal sintered body 3 and the mercury 4 are directly sealed in the heating container 5, but the heating container 5
is usually quite large, so it takes a long time to create a vacuum inside the container. Therefore, the metal sintered body 3 and mercury 4 are sealed in a separate container that can be made into a vacuum atmosphere, and this separate container is used as a heating container 5.
Alternatively, the second step of combining the metal sintered body 3 and mercury 4 may be performed by placing the metal sintered body 3 inside the mercury 4.

持するものでないので、保持器を有するものに比して体
積的に有利となり、同体積でも従来の保持器を有するも
のより多量の水銀を内蔵できる。その結果、その形状を
細く形成しても従来のように長くならずに水銀量を確保
できるので、蛍光放電灯などで管径を著しく細くした場
合であっても、全長に対する有効発光長の比率を小さく
することなく、十分な量の水銀を管内に放出できる。Furthermore, since the mercury-releasing compound is not retained by a retainer, it is advantageous in terms of volume compared to a retainer, and even with the same volume, it can contain a larger amount of mercury than a conventional retainer. can. As a result, even if the shape is made thin, the amount of mercury can be secured without making it as long as in the past, so even when the tube diameter is extremely thin, such as in fluorescent discharge lamps, the ratio of effective light emitting length to total length A sufficient amount of mercury can be released into the tube without reducing the size.
【００３３】さらに、水銀と化合する金属粉末に加えて
水銀と化合しない金属粉末を金属焼結体の一端部を構成
する金属として用いることにより、その組立の溶接作業
の安全性を著しく高くできる。Furthermore, by using a metal powder that does not combine with mercury as the metal constituting one end of the metal sintered body in addition to a metal powder that combines with mercury, the safety of the welding operation for assembling the sintered body can be significantly increased.
【００３４】さらに、本発明の水銀放出構体の製造方法
によれば、水銀は水銀化合物として各工程を流れるので
、水銀単体では存在しない。この結果、製造時の作業性
、安全性が極めて良好なものとなる。Furthermore, according to the method for producing a mercury release structure of the present invention, mercury flows through each process as a mercury compound, so mercury does not exist alone. As a result, workability and safety during manufacturing are extremely good.
