いる。The pulse generator 14 is a pulse generator for transmitting a continuous pulse having a center frequency of, for example, 5 Hz, so that the pulse repetition period changes according to the voltage value of a signal input to a voltage controlled oscillator (VCO). It is configured. This frequency variation range is about several hertz above and below the center frequency. The terminal of the pulse generator 14 is supplied with the voltage at the connection point A via a resistor r2. Therefore, the pulse repetition cycle of the pulse generator 14 fluctuates according to a random signal from the shift register SFR. Shift register S
FR uses the output of the pulse generator 14 as a shift pulse. Therefore, the control signal output to the voltage controlled oscillator (VCO) changes at random in both its voltage value and fluctuation period, and the flip-flop circuit 15 creates a sudden change I portion shown in FIG. .

There is also a bias in the adoption stages, and as described above, the input value of the shift register SFR uses the coincidence detection result of information selected one stage at a time from each of the even and odd numbers, so that the voltage value rises sharply. Extremely fluctuating portions, such as a sudden descent, frequently appear, and the same change pattern is not repeated in a short period of time.

It is transmitted and the oscillation frequency is controlled and changes randomly. Then, a high-frequency signal that changes at random is supplied from the high-frequency oscillator to the high-frequency switching command circuit 10. When a random high-frequency signal is given to the high-frequency switching command circuit 10, a high-frequency switching command is issued from the high-frequency switching command circuit, and the first and second high-frequency switches 5
A and 5B are alternately applied, and the first and second high-frequency switches are turned on and off at a high cycle to form a randomly changing high-frequency alternating current, and a pair of application electrodes 2A and 2B arranged underwater. Are applied alternately.
