Flow-type ultrasonic control technology using a small pump

－－Abstract Algebra Model and Ultrasonic Experimentation and Examination Cycle－－ (Optimization Techniques for Resonance Phenomena and Nonlinear Phenomena) The Ultrasonic System Research Institute has developed ultrasonic <dynamic control> technology that optimizes the interaction of ultrasonic vibrations based on various analytical results of ultrasonic propagation states obtained through an original ultrasonic system (sound pressure measurement analysis and oscillation control) using an abstract algebra model. Note: Control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. Compared to previous control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we are proposing and responding to it as a consulting service (there is an increasing track record in precision cleaning, stirring, and processing at the nano level). Note: Parameters: Power spectrum, autocorrelation, bispectrum, power contribution ratio, impulse response characteristics, and others.

The Ultrasonic System Research Institute provides consulting services for the manufacturing and development methods of the "Deaeration Fine Bubble Generation Liquid Circulation Device," which can efficiently control ultrasonic waves. "Deaeration Fine Bubble 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 deaeration liquid circulation device. 3) As the concentration of dissolved gases decreases, the size of the bubbles generated by cavitation becomes smaller. 4) Through appropriate liquid circulation, microbubbles smaller than 20μ are generated. The above describes the state of the deaeration fine bubble and microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the aforementioned deaeration fine bubble generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles and microbubbles. When measuring the fine bubbles and microbubbles, the distribution of ultra-fine bubbles and nanobubbles becomes greater than that of fine bubbles and microbubbles. The above state indicates that ultrasonic waves can be stably controlled.

The Ultrasonic System Research Institute has developed (and published) methods to apply technologies using ultrasound and fine bubbles/microbubbles to ultrasonic beauty devices for: 1) Techniques to relax and homogenize residual stress on component surfaces 2) Techniques to remove microscopic burrs Through the technology that relaxes surface residual stress using ultrasound and microbubbles, improvements in fatigue strength against metal fatigue can be achieved, leading to the homogenization of the ultrasonic beauty device surface and the efficiency of ultrasonic oscillation and propagation. We have experienced significant changes in the usage conditions of ultrasound (dynamic characteristics of propagation frequency). In particular, the ultrasonic sound pressure level and propagation frequency vary greatly depending on the edge treatment of the metal parts that come into contact with the skin. By performing homogenization treatment, stable reproducibility and long lifespan can be realized. (This has been developed from achievements in ultrasonic cleaning.) This technology is offered as a consulting service. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in self-correlation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (impulse response) 4) Detection of interactions (power contribution rate)

The Ultrasonic System Research Institute conducts consulting related to ultrasonic applications 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 (note) obtained using ultrasonic testers in chronological order, we establish and confirm new evaluation criteria (parameters) that indicate the state of ultrasound suitable for the purpose. Note: Nonlinear characteristics (dynamic characteristics of acoustic flow, bispectrum, autocorrelation... analysis results) We believe that this technology can be applied in various fields and are implementing proposals in various consulting services. We have published materials related to this technology.
