品でも実用されている。Structure of conventional example and its problems A small glass-sealed component is typically a diode, and as shown in FIG. By holding 7 and heating it, the glass tube melts, and the glass and dimet wire are fused, fixed, and sealed. Such a configuration is also used in parts with other functions because of its features such as ease of manufacture, ease of use in shape, and high reliability in that characteristics are not easily affected by environmental conditions.

わせている。 The glass-sealed component having the above structure is manufactured using the second method.
The heater fixture shown in the figure is used.
Number 1 is a resistance member made from a graphite plate.
Part A has many holes so that the members can be set in it. 2 and 3 are electrode plates, usually made of copper. These are stacked one on top of the other as shown in Figure 2b, and members are set in the holes in part A.
When electricity is applied between the resistor 1 and the glass tube 5, the graphite generates heat due to its resistance, causing the glass tube 5 to melt and fuse to the zimet wire.
In the cross-sectional view, the glass tube 5, lead wire 6 and element 7 are inserted into the lower resistance member 1', and the lead wire 6 is inserted into the other resistance member 1 and they are overlapped.

らない。 Next, the heater jig described above is placed in a tank to create a vacuum or annular atmosphere, and then electricity is applied between the electrode plates 2 and 3 to raise the temperature of the resistance members 1 and 1'.
However, the third component was attached to the heater jig shown in FIG.
When the heater jig was set up as shown in the figure and the work was repeated 30 times in an oxygen partial pressure atmosphere of 1.0 Torr in the tank, the temperature inside the heater jig varied by about 30°C.
(The set temperature at this time was 660℃) As seen in the results, the electrode plates 2 and 3 were
As oxidation progresses on the surface of the jig, and due to uneven contact, electricity is not applied evenly to the entire surface of the jig, resulting in uneven temperature within the jig, which can lead to defects in the finished product. arise. In order to prevent this, the oxide film on the electrode plates 2 and 3 must be constantly removed.

ータ治具内の温度バラツキをなくしている。Description of Examples As shown in FIG. 4, the electrode plate 2 of the resistance member 1,
Metal coatings 4 and 4' made of thermally sprayed aluminum were provided at the abutting locations of 3. In this case, after repeating the work 100 times under the same conditions as the conventional example, the temperature variation was 9°C.
It was extremely stable within the range. This improves the electrical contact between the electrode plates 2, 3 and the metal coatings 4, 4', and also generates oxide films on the surfaces of the electrode plates 2, 3, which improves the electrical contact between the electrode plates and the metal coatings. Even if the current is localized, the current is divided by the metal coating portion, and the current is evenly applied between the respective metal coatings 4 and 4', thereby eliminating temperature variations within the heater jig.
