どで構成されている。 The above-mentioned sintered body 15 is extremely important in lowering the starting characteristics of the flash discharge tube and increasing its durability, but since it is difficult to handle, various methods are used to attach the cathode to the glass pipe 16. Measures are being taken. In other words, high-temperature impurity gas (H 2 O, CO, etc.) generated when sealing the cathode
This is to prevent the sintered body 15 from losing its active state due to the influence of cesium chromate. Note that the glass pipe 16 is made of borosilicate glass, quartz glass, or the like.

ウムの蒸気が一部ガラスパイプ１６内に残る。 In the means shown in FIG. 4, after sealing the anode, a connecting wire 11 provided with a sintered body 15 is connected to a glass pipe 16.
After inserting it into the other end, the assembly jig 18 is made to stand up, and the assembly jig 18 is placed in a container 19 and sealed. Subsequently, after filling the container 19 with xenon gas of 1 atm or more, power is supplied to the assembly jig 18 having a heater function via the induction heating coil 20 to seal the cathode. In this method, the cathode becomes red hot due to the influence of induction heating, and the cesium chromate is thermally decomposed and scattered as vapor and does not remain in the sintered body 15. However, since the sealing time is short, the vapor of cesium chromate is portion remains inside the glass pipe 16.

この手段は第３図に示した手段に比べて加熱時
間が長いためクロム酸セシユウムが拡散し易い。 Since this method takes a longer heating time than the method shown in FIG. 3, cesium chromate is more likely to diffuse.

熱溶着される。 The cathode sealed as described above is heated and welded to the beads 13 and the other end of the glass pipe 16 as shown in FIG. 2e.
「発明が解決しようとする問題点」
小型で光出力の高い閃光放電管を製造するため
にはアーク長が長く、ガス圧が高く、起動特性上
昇を防止する必要があるため、陰極内に含浸した
セシユウム酸化物を良好な活性状態に保つ必要が
あつた。``Problem to be solved by the invention'' In order to manufacture a compact flash discharge tube with high light output, the arc length is long and the gas pressure is high, and it is necessary to prevent the starting characteristics from increasing. It was necessary to maintain the cesium oxide in a good active state.
アーク長を長くするため、封着寸法を出来るだ
け短縮する必要があり、封着加熱を行う場合昇温
冷却は時間をかけ徐々に行なう必要があつた。 In order to lengthen the arc length, it is necessary to shorten the sealing dimensions as much as possible, and when heating the sealing, it is necessary to raise and cool the temperature gradually over time.
従来の製造方法では封着温度より易電子放射物
質の分解温度が低いため、封着の際発生する熱的
影響を少なくするため封着時間を出来るだけ短縮
するか、封着部と陰極の寸法を大きく取つて、封
着加熱の際発生する熱的影響を除去する必要があ
り、封着寸法の短縮、封着部と陰極寸法の短縮は
困難の状況であつた。 In conventional manufacturing methods, the decomposition temperature of the electron-emissive material is lower than the sealing temperature, so in order to reduce the thermal effects that occur during sealing, it is necessary to shorten the sealing time as much as possible, or to adjust the dimensions of the sealing part and cathode. It was necessary to remove the thermal influence generated during sealing heating by increasing the size of the seal, making it difficult to shorten the sealing dimensions and the dimensions of the sealing part and the cathode.
第３図に示した第１の従来例の場合、液体窒素
１７の冷却結果でクロム酸セシユウムを分解させ
ずに陰極封着が可能であるが、バーナーによつて
封着するため歪が残ると共に封着寸法が長くなつ
て小形化が難かしく、その上、クロム酸セシユウ
ムが加熱による不純ガスの影響を受け活性状態悪
くなる。 In the case of the first conventional example shown in Fig. 3, cathode sealing is possible without decomposing the cesium chromate as a result of cooling with liquid nitrogen 17, but since the sealing is performed using a burner, distortion remains and The sealing dimension becomes long, making it difficult to downsize, and furthermore, cesium chromate is affected by impurity gas due to heating and becomes less active.
また、バーナーを使つて封着するため生産能率
が低いばかりでなく、ガラスパイプ１６を長く必
要とし、液体窒素１７を使用する関係でコスト高
の製品となる。 Furthermore, since sealing is performed using a burner, not only is the production efficiency low, but the glass pipe 16 is long and liquid nitrogen 17 is used, resulting in a high-cost product.
第４図に示した第２の従来例の場合、１回の封
着作用で４本〜10本程度の陰極封着が可能であ
り、また、陰極の封着寸法が第３図の方法より短
くアーク長を長くできて有利であるが、クロム酸
セシユウムが焼結体１５に残らないため耐久性の
悪い製品となる。 In the case of the second conventional example shown in Fig. 4, it is possible to seal approximately 4 to 10 cathodes in one sealing action, and the sealing dimensions of the cathodes are smaller than those of the method shown in Fig. 3. Although it is advantageous because the arc length can be shortened and the arc length can be increased, the product has poor durability because cesium chromate does not remain in the sintered body 15.
したがつて、焼結体１５と陰極封着部との間の
距離を大きくする必要がある。 Therefore, it is necessary to increase the distance between the sintered body 15 and the cathode sealing part.
第５図に示した第３の従来例の場合、１回の封
着作業で500本〜600本の陰極封着ができ、その
上、封着歪も少なく最も量産に適した手段である
が、加熱時間が第３図、第４図の方法と比較し長
いため焼結体１５にはクロム酸セシユウムが最も
残らないため、起動特性が高く耐久性に劣る製品
となる。 In the case of the third conventional example shown in Fig. 5, 500 to 600 wires can be cathode-sealed in one sealing operation, and it has less sealing distortion and is the most suitable method for mass production. Since the heating time is longer than in the methods shown in FIGS. 3 and 4, the least amount of cesium chromate remains in the sintered body 15, resulting in a product with high starting characteristics and poor durability.
「問題点を解決すための手段」
本発明は上記した問題点にかんがみ開発したも

明する。"Example" Next, an example of the present invention will be described with reference to the drawings.
第１図ａ〜ｄは閃光放電管の製造工程を示す図
である。 1A to 1D are diagrams showing the manufacturing process of a flash discharge tube.
基体金属の焼結体１５はクロム酸セシユウムを
含浸させずに継導入線１１に加締め止めする。 The sintered body 15 of the base metal is crimped to the connecting wire 11 without being impregnated with cesium chromate.
このように構成した陰極はガラスパイプ１６の
一端から差し込み、ビーズ１３とパイプ一端部と
を加熱溶着して封着する。 The cathode thus configured is inserted into one end of the glass pipe 16, and the beads 13 and one end of the pipe are heat welded and sealed.

ウム２４を適下する。 As shown in FIG. 1b, an injection device 23 such as a dispenser is inserted into the sealed cathode sintered body 15 from the other end of the glass pipe 16, and an appropriate amount of chromium is poured into the sealed cathode sintered body 15 as described above. Drop cesium 24 acid.
続いて、第１図ｃのように、陰極が封着された
ガラスパイプ１６を充分に真空乾燥させて水分を
取り除く。 Subsequently, as shown in FIG. 1c, the glass pipe 16 with the cathode sealed therein is sufficiently vacuum-dried to remove moisture.
次に、ガラスパイプ１６の他端より継導入線１

ーズ１４とを加熱溶着し、第１図ｄに示すように
陽極を封着する。 Next, from the other end of the glass pipe 16, the connecting wire 1
2 is inserted, and the other end of this pipe 16 and this bead 14 are heat welded to seal the anode as shown in FIG. 1d.
上記のように実施すれば、陰極の封着の際にク
ロム酸セシユウムが焼結体１５に含浸されていな
いので、このセシユウムが陰極封着のための加熱
によつて発生した不純ガスの影響を受けることが
ない。 If carried out as described above, cesium chromate is not impregnated into the sintered body 15 when sealing the cathode, so this cesium will not be affected by impurity gas generated by heating for cathode sealing. I never receive it.
また、図示するような細長い注入器具２３を使
用することによつて、ガラスパイプ１６の内面に
クロム酸セシユウムを付着させずに焼結体１５に
含浸させることができる。 Further, by using the elongated injection device 23 as shown, it is possible to impregnate the sintered body 15 with cesium chromate without adhering it to the inner surface of the glass pipe 16.
陽極を封着する際にはその加熱溶着部と陰極と
の間に所定の距離があるので、この加熱によつて
発生した不純ガスは焼結体１５のクロム酸セシユ
ウムに対してほとんど影響しない。 When sealing the anode, there is a predetermined distance between the heat-welded part and the cathode, so the impure gas generated by this heating has little effect on the cesium chromate in the sintered body 15.

ことにより閃光放電管の小形化が可能になる。"Effects of the Invention" As described above, in the manufacturing method of the present invention, the cathode is sealed before the sintered body is impregnated with the radioactive substance, and then an appropriate amount of the radioactive substance is impregnated into the sintered body. At the same time as impregnating the sintered body, the anode is sealed away from the sintered body, so the impurity gas generated by the heat sealing of the cathode and anode has little effect on the electron-emitting radioactive substance, and the active state of cesium is It is possible to mass-produce flash discharge tubes with excellent durability and starting characteristics because there is no influence of impurity gas, and the arc length is reduced by reducing the sealing dimensions and the dimensions of the cathode and sealing part. It is possible to manufacture a flash discharge tube with a long length, increasing the light output compared to conventional products, and by designing it to the same arc length as conventional products, it is possible to downsize the flash discharge tube.
特に一度で500〜600本も封着するバツチ方式の
場合封着時間を長く取る事が可能のため封着むら
が少なく生産性の高い方式である。 In particular, in the case of the batch method in which 500 to 600 sheets are sealed at one time, it is possible to take a long time to seal, resulting in less uneven sealing and high productivity.
