Case studies of dynamic control of ultrasound based on acoustic pressure measurement analysis.

The Ultrasonic System Research Institute provides consulting services for the manufacturing and development methods of the "Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device," which can efficiently control ultrasonic waves. "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 gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the bubble size of the dissolved gas 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). When measuring the fine bubbles (microbubbles), the distribution of ultra-fine bubbles exceeds that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled.

The Ultrasonic System Research Institute is applying and developing manufacturing technology for original ultrasonic probes. We have developed technology to optimize the nonlinear vibration phenomenon of surface acoustic waves through oscillation control technology based on the acoustic characteristics of the probes, and we provide consulting services for various ultrasonic utilization technologies. Note 1: Original nonlinear resonance phenomenon The resonance phenomenon of ultrasonic vibrations occurs due to the generation of harmonics resulting from original oscillation control of ultrasonic waves, which achieves high amplitude through resonance. The key point is the optimization of the ultrasonic propagation section. Note 2: By relaxing and homogenizing surface residual stress, stable ultrasonic oscillation control becomes possible. Technology for setting oscillation control conditions: 1) Setting of oscillation waveforms corresponding to the ultrasonic propagation characteristics of the device/equipment. 2) Setting of sweep conditions corresponding to the ultrasonic propagation characteristics of the device/equipment. 3) Setting of output levels corresponding to the ultrasonic propagation characteristics of the device/equipment. 4) Adjustment of various interactions corresponding to the ultrasonic propagation characteristics of the device/equipment.

The Ultrasonic System Research Institute has developed ultrasonic control technology by applying the "Mathematical Theory of Communication" (Claude E. Shannon) to ultrasound. The developed technology utilizes ultrasonic sound pressure measurement, analysis, and evaluation techniques to adapt the propagation characteristics of ultrasound (dynamic characteristics) to the ensemble (entropy) of communication theory. Unlike the previous "technical problems" related to communication, this was developed as a technical application research addressing the "semantic problems" and "effect problems" related to ultrasonic phenomena. Furthermore, through the "evaluation technology for ultrasonic devices" at the Ultrasonic System Research Institute, concrete results using this method have been confirmed. For more details, we are responding and expanding this as a consulting business.

Application of technology to analyze and evaluate the dynamic characteristics of ultrasound The Ultrasound System Research Institute has developed a method (system) for the analysis and evaluation of ultrasound, utilizing measurement, analysis, and control technology related to the nonlinearity of ultrasound. Using this technology, we are providing on-site support for the additional installation of a degassing fine bubble generation liquid circulation system. To utilize (control) the complex and changing conditions of ultrasound in a stable manner according to the purpose, we offer on-site services to add, install, and confirm sound pressure measurements for the degassing fine bubble generation liquid circulation system in specific tanks present at the site. <Example> *Month* *Day* - Consultation and confirmation via email *Month* *Day* 13:00 - 13:30 - Greetings and meeting 13:30 - 16:30 - Confirmation (simple sound pressure measurement) Setting up the degassing fine bubble generation liquid circulation system Operation explanation Confirmation (sound pressure measurement) 16:30 - 17:00 - Discussion based on sound pressure data 17:00 - 18:00 - Reserve A simple analysis of the measurement data will be conducted.
