れる欠点があつた。 At present, this type of gas-filled discharge tube includes a diode discharge tube (a) made up of sealed parts as shown in Figure 1A, a triode discharge tube (b) as shown in Figure 1B, or (not shown). Multipolar discharge tubes with multiple electrodes are used. Figure C shows the component configuration of an unsealed object 1 of a triode discharge tube. At the same time, the intermediate electrode 5 is inserted between the metal electrode 4 and the intermediate opening of the cylindrical insulating tube 2 through a heat-melting adhesive, for example, silver solder 3, and the silver solder 3 is heated and melted. Electrodes 4, 4 on the cylindrical insulating tube 2,
5 is bonded to seal the inside with gas. Conventionally, in the production of this type of gas-filled discharge tube, as shown in FIG.
After the turntable 6 is covered with a bell gear 8 and exhausted, a predetermined gas is introduced, and the heating coil 1 is heated by the intermittent rotation of the turntable 6.
The tray 7 was raised at the 0 position, the plate spring 9 was used to press the unsealed object 1 from above, and the unsealed object 1 was sealed by high-frequency heating by the heating coil 10. When individually sealed in this way, impure gas is generated or the gas pressure increases due to heating, resulting in a subtle change in the gas atmosphere inside the bell gear, making it different from the one originally sealed. There was a drawback that the purity of the sealed gas was different, and gas-filled discharge tubes with different discharge starting voltages were manufactured from the same lot.
又、ターンテーブル6の大きさから受皿7の数
に制限が生じ、少ない封着個数にも拘ず、ガスの
排気、封入に所定時間を要するので、一個当りの
封着時間が長くなつていた。 In addition, the number of saucers 7 is limited due to the size of the turntable 6, and even though the number of sealing plates is small, it takes a certain amount of time to exhaust and fill the gas, so the sealing time for each plate is long. .

る。 A feature of the present invention is that the gas sealing jig is provided with vertical holes into which unsealed gas-filled discharge tubes are inserted in multiple stages. For example, when unsealed items are placed side by side, a sufficient lateral load must be applied to each unsealed item, and silver solder that melts as it is heated flows out along the bottom of the sealed surface. Therefore, complete sealing cannot be achieved. By stacking these in multiple stages in the vertical direction, gas-filled discharge tubes with the same characteristics can be mass-produced at once, the sealing surface is held horizontally to prevent silver solder from flowing out, and the It has the characteristic that if a load is applied, a sufficient load can be transmitted to each unsealed object. As the gas-filled discharge tube to be sealed with this sealing jig, a cylindrical ceramic body made of ceramic or the like that does not undergo thermal deformation under load is selected.

It can be moved and pushed in, and each unsealed item can be regulated by the inner wall and stacked in multiple stages accurately. Furthermore, during sealing, subtle pressure changes in the gas and cohesive force due to melting of the silver solder may cause the components to lift, but this is prevented by applying a load from the top of the vertical hole. Hereinafter, the present invention will be explained based on an embodiment shown in FIG. 3 and subsequent figures.

A large number of holes are drilled in a regular array at regular intervals. The jig 11 is made of metal that can withstand high temperatures without generating impurity gas when used in a gas atmosphere.
It is formed into a substantially rectangular body. Of course, the jig may be formed into a cylindrical body corresponding to a bell gear or the like, and the vertical holes may be bored in an arbitrary arrangement. The vertical hole 12 is drilled through and locks and fixes the bottom plate 13 to form a bottom portion 14. The vertical hole 12 is set to have a vertical length that leaves a margin equal to an integral multiple of the unsealed object 1 from the bottom 14 to the top 15 of the hole, and a weight ball 16 is inserted into the margin as a pressurizing means. Further, the vertical hole 12 is provided so that the vertical hole inner wall 17 is close to the projected surface of the outer periphery of the unsealed object 1. That is, the vertical hole inner wall 17 is formed into a cylindrical shape corresponding to the metal electrode 4 that protrudes the most at the outer peripheral portion of the unsealed object 1, and is provided with a vertical groove 18 corresponding to the protruding portion of the intermediate electrode 5, so that the sealing The unsealed object 1 to be assembled and inserted is so close that it can be pushed in without falling.

Next, if the unsealed objects 1 are sequentially inserted from the upper part 15 of the vertical hole, the unsealed objects 1 and 1.
1... are stacked vertically in multiple stages to be sealed in the vertical hole, and after inserting the desired number of balls, the weight balls 16 are inserted into the top stage. Similarly, insert the unsealed object 1 and the weight ball 16 into the other vertical holes 12..., and then insert the jig 11.
is installed inside the bell gear. After installation, the inside of the bell gear is evacuated and then gas is introduced, so that gas having the same characteristics is introduced into each unsealed object 1. If heating is then promoted, the gas temperature will rise and heat the jig 11 and the electrodes 4, 4, 5 of the unsealed object 1...
Each silver solder 3 is melted uniformly, and the weight ball 16 is
Due to the vertical load and the position regulation of the vertical hole inner wall 17 and the vertical groove 18, each unsealed object 1 is accurately sealed. In this case, since gas introduction and heating are performed simultaneously, gas-filled discharge tubes with the same characteristics are manufactured.

の未封着物に均等な荷重を伝達可能である。 According to the present invention, it is possible to provide a novel gas sealing jig for gas-filled discharge tubes, which has a large number of bottomed vertical holes that can seal unsealed objects in multiple stages.
When installed and used in conventional manufacturing equipment, the same gas atmosphere can be introduced into stacked unsealed objects in multiple stages to mass-produce gas-filled discharge tubes with the same characteristics. In particular, since they are stacked in multiple stages in a vertical hole, they do not collapse from the stacked parts, and accurate horizontal positioning can prevent silver solder, etc. from flowing out, and if a single load is applied in the vertical direction, each unsealed item is evenly distributed. It is possible to transmit large loads.

る。 Furthermore, since the load is applied to the unsealed objects stacked in multiple stages from the top, lifting of the unsealed objects due to heating can be completely prevented. When a weight ball is used as a load, unlike a spring, the same load can be applied at all times without losing spring elasticity due to high temperature during heating and reducing the pressing force. In addition, a flat plate can be used as a pressurizing means. In this case, unsealed items can be piled up to a height that exposes them from the top of the vertical hole, and a flat plate can be placed on top of each unsealed item to easily apply pressure at the same time. It is.
