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.

Sound flow control technology

The Ultrasonic System Research Institute has developed ultrasonic cleaning technology that enables control of acoustic flow (ultrasonic propagation state) from 1 to 100 MHz by utilizing a megahertz ultrasonic oscillation control probe in relation to ultrasonic cleaners. This is a new application technology for precision cleaning, processing, and stirring based on the measurement, analysis, evaluation, and technology of ultrasonic propagation states. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation to the target object can be controlled even in a 1000-liter tank with ultrasonic output below 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic wave phenomena and an abstract algebraic model of ultrasound. The key point is the use of tools (elastic bodies: metal, glass, resin). By confirming the propagation characteristics of ultrasound depending on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This phenomenon occurs due to the generation of harmonics resulting from original oscillation control, which is realized at high amplitudes through resonance phenomena, leading to ultrasonic vibration resonance.

Relaxation and uniform treatment of surface residual stress using ultra-fine bubbles and megahertz acoustic flow control.

<<Deaeration Fine Bubble Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the size of the bubbles formed by cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles, and when measuring the fine bubbles, the distribution of ultrafine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In the state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz ultrasonic waves. The method of controlling the sound pressure level is achieved by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasonic waves, setting and controlling it to an effective dynamic state.
