We provide manufacturing technology for ultrasonic sound pressure measurement analysis systems—evaluation technology for ultrasonic propagation characteristics.

A megahertz ultrasonic oscillation control probe that enables the utilization of ultrasonic propagation conditions from 1 to 900 MHz.

The Ultrasonic System Research Institute has developed a megahertz ultrasonic oscillation control probe that enables the utilization of ultrasonic propagation states from 1 to 900 MHz by combining it with a function generator for controlling ultrasonic propagation states. This is a new application technology based on measurement, analysis, and evaluation techniques of ultrasonic propagation states for precision cleaning, processing, stirring, and inspection. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled for structures and machine tools weighing several tons, even in a 3000-liter water 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 waves and an abstract algebraic ultrasonic model. The key point is the technology for utilizing surface elastic waves on the surface of ultrasonic elements. By confirming the propagation characteristics of ultrasonic waves depending on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon. Note 1: Propagation characteristics of ultrasonic waves include nonlinear characteristics, response characteristics, fluctuation characteristics, and effects due to 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.

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.

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

The Ultrasonic System Research Institute is developing technologies related to effective "measurement, analysis, and evaluation methods" utilizing a <statistical approach> in the field of ultrasonic applications. <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. Regarding ultrasonic research, "a statistical perspective is essential for stabilizing the effects of cavitation." <About models> Models are constructed with the aim of effectively advancing understanding, prediction, control, etc., regarding the subject. Constructing an accurate model is difficult, and discussions are always conducted using a suitably "rounded" representation of the complexity of the subject. In that sense, the process of constructing or building a model requires statistical thinking. Propagation characteristics of ultrasound: 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 characteristics) 4) Detection of interactions (analysis of power contribution rates)
