るように制御される。That is, a reference temperature T2 is set in the temperature setting circuit (9), and the reference temperature '■'2 and the detected temperature of the temperature detection circuit (7) are compared and amplified in the comparison amplifier circuit (8), and the detected temperature is When it is lower than T2, the Hayabusa pressure is I! to set the transmission output level to the specified value PO. ! , is output from the quasi-voltage setting circuit (4), and is controlled so that the transmission (M output level is PoH). Also, if the detected temperature is higher than 1゛2, the standard for setting the transmission output level to Pl. The voltage is output from the reference voltage setting circuit (4 points) and the integrated control amplifier (5 points).
) The drive current of the transmission amplifier (2) is controlled so that the transmission output level becomes a specified value 411P+, which is smaller than the above Po.

ちつくわけである。As shown in Figure 3 (bl), the transmission output level is PO while the temperature is lower than 12, or when the temperature exceeds 12, the output level starts to decrease and the output level is (At the same time, the temperature will also approach the accuracy TI that will settle down during a long flight at the output level P1. In other words, the control function of the A device will cause the temperature to approach the accuracy TI that will settle down during a long flight at the output level PO. This is why the temperature TB is lower than the temperature TO which it settles down to.

It is possible. Further, in the above embodiment, the same effect can be obtained for the Mukasada Tantei Hikari, which requires miniaturization, as compared to the case of the Second Motion Driving Machine.
