To stabilize the effects of cavitation, a statistical perspective is essential.

The Ultrasonic System Research Institute is developing an effective "Ultrasonic Oscillation Control System" based on a statistical approach using abstract algebra in relation to the utilization of ultrasound. Regarding the statistical approach, statistical mathematics has both abstract and concrete aspects, and through contact with concrete entities, abstract ideas or methods are developed; this is the characteristic of statistical mathematics. In the research of ultrasound, "a statistical perspective is essential to stabilize the effects of cavitation." About the model: Models are constructed with the aim of effectively advancing understanding, prediction, control, etc., regarding the subject. Constructing an accurate model is difficult, and the examination progresses with representations that appropriately "round off" the complexity of the subject. In that sense, the process of constructing or building a model requires statistical thinking.

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.

Dynamic control of ultrasound to achieve stress relaxation on metal surfaces.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing two function generators. By generating oscillations with two different waveforms (sweep), we have achieved a technique to control the nonlinear phenomena of ultrasound. Note: The generation of (10th order and higher) harmonics caused by original oscillation control is realized by resonating with low-frequency vibration phenomena, resulting in the generation of high-amplitude harmonics, which is a nonlinear (resonance) phenomenon of ultrasonic vibrations. By optimizing the ultrasonic propagation characteristics of various components according to their intended purpose, efficient ultrasonic oscillation control becomes possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this system technology allows for the dynamic control of surface elastic wave changes according to the intended application. Practically, multiple (two types of) ultrasonic probes generate multiple (two types of) oscillations (sweep oscillation, pulse oscillation), which create complex vibration phenomena (original nonlinear resonance phenomena), achieving high sound pressure propagation states at high frequencies or low sound pressure levels at frequencies matched to the desired natural frequency.
