Consulting for the development of an ultrasonic cleaning system based on sound pressure data analysis.

The Ultrasonic System Research Institute is applying measurement, analysis, and evaluation techniques related to the propagation state of ultrasound to publish technology that relaxes the surface residual stress of ultrasonic transducers using ultrasound and fine bubbles. This technology for relaxing surface residual stress has made it possible to improve fatigue strength against metal fatigue. As a result, the effects on various components, including ultrasonic tanks, have been demonstrated.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing multiple function generators. This technology enables the control of nonlinear ultrasonic phenomena through oscillation with several different waveforms (sweeping). Note: Nonlinear (resonance) phenomena By generating harmonics of the 10th order or higher through original oscillation control and resonating with low-frequency vibration phenomena, the generation of high-amplitude harmonics has been achieved, resulting in nonlinear (resonance) phenomena 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 dynamically controls the changes in surface elastic waves according to the intended application.

The Ultrasonic System Research Institute conducts consulting related to the use of ultrasound by utilizing a technology that measures, analyzes, and evaluates the propagation state of ultrasound, applying feedback analysis techniques based on multivariate autoregressive models. By organizing the measurements, analyses, and results obtained using ultrasonic testers in a time series, we have developed a new evaluation standard (nonlinear phenomenon analysis parameters) that indicates the state of ultrasound suitable for the purpose. Note: - Nonlinear characteristics (harmonic generation characteristics) - Response characteristics - Fluctuation characteristics - Effects due to interactions 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)

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.
