- Technology for controlling oscillations of low-frequency resonance phenomena and high-frequency nonlinear phenomena -

<<Analysis and Evaluation of Ultrasonic Sound Pressure Data>> 1) Regarding time series data, we will analyze and evaluate the statistical properties of the measurement data (stability and changes of ultrasound) through feedback analysis using a multivariate autoregressive model. 2) The effects of the oscillation part due to ultrasonic oscillation will be analyzed and evaluated in terms of the response characteristics of ultrasonic vibration phenomena concerning the surface condition of the target object through impulse response characteristics and autocorrelation analysis. 3) The interaction between the oscillation and the target object (cleaning items, cleaning solution, water tank, etc.) will be evaluated through the analysis of power contribution rates. 4) Regarding the use of ultrasound (cleaning, processing, stirring, etc.), we will analyze and evaluate the dynamic characteristics of ultrasound based on the nonlinear phenomena (results of bispectral analysis) of the target object (propagation of surface elastic waves) or the ultrasound propagating in the target liquid, which are the main factors of the ultrasonic effect. This analytical method is realized based on past experiences and achievements, adapting the analysis techniques of time series data to the measurement data of ultrasound to capture the dynamic characteristics of complex ultrasonic vibrations. Ultrasonic propagation characteristics: 1) Detection of vibration modes 2) Detection of nonlinear phenomena 3) Detection of response characteristics 4) Detection of interactions

Ultrasonic cleaning system that achieves ultrasonic control tailored to the purpose.

This is an effective device using a dedicated ultrasonic tank (original manufacturing method). Due to the high efficiency of ultrasonic utilization, standard tanks lack sufficient strength and durability. Depending on the target and purpose, multiple ultrasonic waves and a degassing fine bubble generation liquid circulation device are controlled based on sound pressure measurement analysis for cleaning, stirring, and surface modification. We propose various combinations and usage (control) methods. The key point is to achieve an ultrasonic propagation state tailored to the target, focusing on the "dissolved oxygen concentration distribution" and "liquid circulation" within the dedicated tank. << Degassing 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 degassing liquid circulation device. 3) As 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) smaller than 20μ are generated. The above describes the state of the degassing microbubble generation liquid circulation device.

Ultrasonic oscillation (sweep oscillation) system for controlling nonlinear phenomena

The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface elastic waves based on the acoustic characteristics of original ultrasonic probes. The key point is the setting of sweep oscillation conditions using two ultrasonic probes (essentially, it cannot be controlled with just one probe for ultrasonic oscillation control. By combining the oscillation settings of the two probes, the occurrence of resonance phenomena and nonlinear phenomena can be controlled). Resonance phenomena and nonlinear phenomena can be controlled within a frequency range tailored to the intended use. In particular, when strong stimulation is required, this is achieved by utilizing low-frequency resonance phenomena (e.g., breaking glass). When high-frequency stimulation is needed, this is achieved by utilizing high-frequency nonlinear phenomena (e.g., 700 MHz stimulation).

Regarding the characteristics of piezoelectric elements, we develop and manufacture original ultrasonic probes based on analyses that consider elastic wave propagation and various vibration states (modes). For measurements, the probes can be connected to an oscilloscope for use. For oscillation, they can be connected to a function generator. By performing feedback analysis of sound pressure measurement data, it becomes possible to quantify and evaluate nonlinear ultrasonic phenomena (acoustic streaming) and cavitation effects. The ultrasonic probes are "made-to-order" based on the confirmed intended use.

- Technology for controlling nonlinear vibration phenomena through oscillation control of original ultrasonic probes -

The Ultrasonic System Research Institute has developed oscillation control technology based on the acoustic characteristics of probes through the manufacturing technology of original ultrasonic probes. This has evolved into technology for controlling the nonlinear vibration phenomena of surface acoustic waves. The key point is the optimization control method for ultrasonic oscillation control tailored to the propagation characteristics of surface acoustic waves on the surface of ultrasonic elements and their intended use (conditions for combining sweep oscillation and pulse oscillation). To achieve this, it is important to dynamically evaluate the propagation state of ultrasound through operational verification of the ultrasonic propagation characteristics of the original probe (sound pressure level, frequency range, nonlinearity, dynamic characteristics, etc.). In particular, it is necessary to measure, analyze, and evaluate the dynamically changing oscillation characteristics of the ultrasonic probe (or element) and the oscillator (function generator) regarding their transmission and reception characteristics. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response) 4) Detection of interactions (analysis of power contribution rates)

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

The Ultrasonic System Research Institute is developing technologies related to effective "measurement, analysis, and evaluation methods" using a <statistical approach> concerning the utilization of ultrasound. <About the Statistical Approach> Statistical mathematics has both abstract and concrete aspects, and through contact with concrete entities, abstract thoughts or methods are developed. This is the characteristic of statistical mathematics. - From "Statistics in Science" edited by Hirotsugu Akaike <About Models> Models are constructed with the aim of effectively advancing understanding, prediction, and control regarding the subject. Building an accurate model is difficult, and the examination is always conducted in a form that appropriately "rounds off" the complexity of the subject. In this sense, the process of constructing or building a model requires statistical thinking. <About the Relationship Between Models and Current Systems> (Points to Consider When Reflecting) 1) It is necessary to consider that preconceived notions and experiences may not be correct. 2) To think about the essence of a model, I believe it is effective to utilize category theory.

The Ultrasonic System Research Institute has developed "ultrasonic oscillation control (processing) technology" that utilizes the acoustic characteristics (vibration response characteristics and nonlinear phenomena) of objects (tools, target items, etc.) through a sound pressure measurement analysis device (ultrasonic tester) and a megahertz ultrasonic oscillation control probe. With this developed technology, it has become possible to control nonlinear vibration phenomena in target objects through "ultrasonic oscillation and output control," achieving dynamic control of ultrasonic waves (changes in bispectrum). The original ultrasonic oscillation control probe allows for the utilization and control of nonlinear effects of ultrasonic vibrations. This is an effective ultrasonic utilization (control) technology tailored to applications such as processing, cleaning, surface modification, and promoting chemical reactions. There are interactions with the acoustic characteristics of cutting tools (drills, reamers, cutters, knives, etc.) and the size and material of cutting oils, jigs, and target objects, making the analysis (self-correlation, impulse response, contribution rate, bispectrum) complex. However, various optimizations based on the analysis results of sound pressure measurement data become possible.
