Ultrasound propagates through the uniform liquid, generating a stable state of ultrasound. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). This involves achieving a uniform sound pressure distribution throughout the tank, optimizing ultrasound, liquid circulation pumps, fine bubbles, etc. The operational control becomes the know-how for individual tanks.

Application technology for ultrasonic sound pressure measurement, analysis, control, and evaluation systems.

The Ultrasonic System Research Institute has developed technology to control resonance and nonlinear phenomena in the propagation state of surface acoustic waves through the control of ultrasonic oscillation, using a combination of low and high frequencies. By utilizing new ultrasonic propagation materials (such as stainless steel wire and titanium straws), efficient ultrasonic applications tailored to specific purposes become possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this system technology controls the complex changes in surface acoustic waves according to the intended use. Practically, by using multiple (two types of) ultrasonic probes to generate multiple (two types of) oscillations (sweep oscillation and pulse oscillation), complex vibration phenomena (original nonlinear resonance phenomena) are created, achieving high-frequency propagation states at high sound pressure or low-frequency propagation states tailored to the desired natural frequency. In particular, by optimizing the vibration characteristics of tanks and pumps with megahertz ultrasound, efficient ultrasonic control is realized (propagating through 3000 liters of cleaning solution at a 30W output).

Technology for controlling low-frequency resonance phenomena and high-frequency nonlinear phenomena.

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology utilizing nonlinear vibration phenomena based on surface acoustic waves. By confirming the basic acoustic characteristics (response characteristics, propagation characteristics) for various targets (water tanks, transducers, probes, jigs, objects, etc.), the desired ultrasonic propagation state can be achieved through oscillation control. By setting the oscillation conditions (waveform, output, control, etc.) with an original nonlinear resonant ultrasonic oscillation probe, we optimize high-frequency propagation states above 300 MHz through high sound pressure resonance phenomena and harmonic generation phenomena (nonlinear phenomena). This technology is an efficient method for utilizing low-output ultrasonic oscillation. The key point is the setting of various parameters utilizing the characteristics of a discrete function generator through digital control. By using the nonlinear resonant ultrasonic oscillation probe, the control range of sound pressure levels due to resonance phenomena is greatly expanded, which is significantly different from conventional sound pressure levels caused by resonance phenomena. Therefore, optimization of control settings based on sound pressure measurement analysis is necessary to avoid phenomena such as damage or destruction.
