Abstract

PURPOSE:To obtain the titled machine, through which defectives are not generated from materials to be machined, by generating an alarm signal when the oscillation frequency of an ultrasonic vibration element is not kept at a value within the range of predetermined fundamental frequency. CONSTITUTION:Maintaining of values VL-VH within a range previously determined of an electric signal detected by the oscillation frequency detector 23 detecting an electric signal Vf proportional to the actual oscillation frequency (f) of the ultrasonic vibration element 7 is discriminated by a discriminating means 24. An alarm display means 30 generates the alarm signal when the result of discrimination is not kept within the range of the values VL-VH. When exchanging a horn 8 for machining, the alarm signal is generated when the horn 8 for machining is vibrated by frequency except fundamental frequency f0, and the generation of trouble is notified.

The power supply voltage VC is applied to each variable DC power supply 22 (1), and the output voltage vO controlled by the DC voltage VD is applied to the variable amplification degree i+I1 width circuit 18 (=I). The output voltage \/Q becomes lower as the DC voltage VD becomes higher,
The lower the DC voltage VD is, the higher it becomes. The amplification factor of the variable amplification amplifier circuit 18 is proportional to its output voltage vO. Therefore, when the vibration frequency f of the ultrasonic vibrating cord 7 decreases, the voltage value of the high frequency signal SG1 decreases, and the DC type J:I
i V D decreases and output voltage VO increases. J to this

Further, the suitcase 29 is an analog switch drive circuit 31.
When the user is turned to the side (l1i), the discriminating means 27'I
When the logic 1 discrimination signal S G 4 is output from the attenuator 1G, the no-no switch drive circuit 331 is activated.
Jt, 1 gusuitsuji 17. The attenuation rate of the attenuator 16 is R1/(R1-+-R2+R3) when the analog switch 17 is turned off.
When the analog switch 17 is turned on, R1/(R1
-1-R3) Yell. Therefore, when the analog switch 17 is turned on, the attenuation rate of the attenuator 16 increases, and the overall voltage gain of the oscillation circuit 9 decreases. As a result, even if the ultrasonic vibration element 7 has a peak 111'1 of the spurious characteristic f[ at a frequency close to the fundamental frequency fo, the peak value is usually lower than the peak value of the fundamental frequency fO. At a frequency other than 0, the fundamental frequency fOC oscillates.The DC voltage V output from the frequency detection device 23 is 1.1r11. If the values of the DC voltages VI- to Vl+ outputted from the 25th input are within the range J, the discriminating means 2/I outputs a logic ○ signal.Therefore, the analog switch drive circuit 3'1 It does not operate, and the analog switch 17 is turned off.As a result, the overall electric gain of the oscillation circuit 9 returns to the original 1111, and the -C ultrasonic vibration element 7 vibrates at the fundamental frequency [().
