Leading to new applications of ultrasound from sound pressure and vibration data of ultrasound.

Application of ultrasonic sound pressure measurement, analysis, and evaluation technology The Ultrasonic System Research Institute has developed a method for the analysis and evaluation of ultrasound (system technology) that applies measurement, analysis, and control technology related to the nonlinearity of ultrasound. Using this technology, we will provide measurement, analysis, and evaluation support for ultrasonic devices. For specific support and costs, please contact us via email. *Comment* Currently, regarding the use of ultrasound, I believe it is very difficult to detect and confirm the optimal ultrasonic state for the intended purpose. Therefore, by incorporating "sound pressure data" into the daily management of ultrasound, we aim to resolve the relationship with the final evaluation state (defect rate, yield, etc.) through the accumulation and analysis of statistical data. By analyzing using time-series data analysis technology, effective improvements have been realized. As a result of continuing such improvements, the number of successful cases using low-output ultrasonic oscillation control has increased. We have been manufacturing and selling our original product: ultrasonic systems (sound pressure measurement analysis, oscillation control) since March 2021.

Ultrasonic control technology based on the classification of nonlinear phenomena in which ultrasonic vibrations propagate.

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibration propagation by analyzing measurement data of ultrasonic propagation states using bispectral analysis. The method developed in this instance estimates the linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequencies (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to classify effective utilization methods into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type There are numerous successful cases of device development and control settings based on each of the above types.

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).

A technology has been developed to control the nonlinear phenomena of ultrasonic vibrations propagating to the target object based on classification techniques of ultrasonic waves and oscillation control.

We provide consulting services for the development of ultrasonic systems utilizing the following device. <<Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) 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 (microbubble) generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles (microbubbles), and when measuring the fine bubbles (microbubbles), the distribution of ultra-fine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled.
