して対応していた。There are various gas generation characteristics required of this gas generator, but the two cases shown in FIG. 10 are most frequently required. In Figure 10, Case 1 and Case 2 both show the change in gas generation rate over time as the gas generation characteristics, and Case 1
Case 2 is a case where rapid gas generation is required for a short period of time, and case 2 is a case where there is no need to generate gas too vigorously, but a quick initial rise and a stable gas generation state is desired for a long period of time. It is. Conventionally, these two cases have been dealt with by adjusting the content of the second component, which is a reaction accelerator.

In particular, efforts have been made to adjust the CoCA2 content. However, although it is relatively easy to obtain performance close to the gas generation characteristics of Case 1, it is not necessarily easy to maintain stable gas generation for a long period of time as in Case 2, and the above method does not provide satisfactory performance.

た。Although various gas generation patterns may be required, cases 1 and 2 in FIG. 10, which are most frequently required, are taken here as examples. Both cases show the change in gas generation rate over time as a gas generation characteristic; case 1 requires rapid gas generation for a short period of time; case 2 does not require rapid gas generation; This is the case when it is desired to maintain a stable gas generation state for a long time. The rate of gas generation is also greatly affected by the temperature of the water. Therefore, in order to maintain the gas generation characteristics of Case 1 or Case 2 at any water temperature, it is necessary to adjust the content of the second component of the gas generating agent pellets and/or the contact area with water. FIG. 1 is a diagram showing an example of a gas generating agent pellet in which the above two factors are adjusted. In this example, CoCf2 was used as the second component.

ケース２のガス発生特性を得ることができた。Figure 5 shows the case where the gas generation characteristics of Case 2 are obtained when the water temperature is 20°C or higher. In order to speed up the initial rise and maintain a constant gas generation rate for a long time, it is necessary to combine two or more types of gas generation characteristics. If the contact area of the gas generating agent with water per unit weight is increased, gas will be generated violently at the same time as the contact with water begins, and the initial rise of the gas generation rate will be faster. Further, by reducing the contact area of the gas generating agent with water per unit weight, the gas generating agent gradually generates gas and can maintain a constant gas generation rate for a long time. Therefore, type A Co

In this case, the temperature is a little lower, so the gas generation rate is a little slower. Therefore, in order to compensate for this, as shown in FIG. 6, the CoC
By combining type CO gas generating agent pellets 3 with an increased l12 content to 30 wt% and type E gas generating agent pellets 5 with an increased CoCl2 content of 20 wt%, the initial rise in the gas generation rate is reduced.
