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.

The Ultrasonic System Research Institute utilizes a <degasification and microbubble generation liquid circulation system> to achieve effective ultrasonic control tailored to specific purposes. Explanation of Ultrasonic Liquid Circulation Technology 1) We use a dedicated ultrasonic tank (original manufacturing method). 2) The installation of the tank involves: 1: Using specialized materials. 2: Optimizing the natural vibration, ultrasonic frequency, and output. 3) The ultrasonic transducer is installed using specialized materials. (These materials can limit the utilization states of standing waves, cavitation, and acoustic flow.) 4) We use a degasification and microbubble generation device. (The standard dissolved oxygen concentration is 5-6 mg/l.) 5) The tank and ultrasonic transducer undergo surface modification. With the above settings and the diffusibility of microbubbles, a uniform cleaning liquid state is achieved. Ultrasonic waves propagate through the uniform liquid, generating a stable ultrasonic state. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). The operation control of the ultrasonic device, degasification device, liquid circulation pump, etc., is our expertise.

The Ultrasonic System Research Institute has developed a liquid circulation technology for ultrasonic cleaners that utilizes the "Constructal Law" related to flow and shape (control of nonlinear phenomena). This was developed with inspiration from observations of river flows, as shown in the attached photo. Regarding the use of ultrasound, we believe that through our experience in observing flow, we can intuitively grasp acoustic flow (a nonlinear phenomenon of ultrasound). Acoustic flow <General Concept> When finite amplitude waves propagate through a gas or liquid, acoustic flow occurs. Acoustic flow is a unidirectional steady flow of matter that arises either as a result of viscous losses from wave pulses in a free inhomogeneous field, or in the vicinity of obstacles (cleaning objects, fixtures, liquid circulation) within an acoustic field, or near vibrating bodies due to inertial losses. Using the above as a reference and hint, we organize the technology for measuring, analyzing, evaluating, and utilizing (controlling) "nonlinear phenomena" in ultrasonic propagation phenomena through the "Constructal Law," which improves flow, thereby consolidating it into ultrasonic technology.

Regarding complex vibration states: 1) Linear phenomena and nonlinear phenomena 2) Interactions and the acoustic characteristics of various components 3) Sound, ultrasound, and surface elastic waves 4) Low frequency and high frequency (harmonics and subharmonics) 5) Oscillation waveforms and output balance 6) Oscillation control and resonance phenomena ... Based on the above, we optimize a new evaluation method for surface elastic waves using a statistical mathematical model based on sound pressure measurement data. Ultrasonic cleaning, processing, stirring, ... surface inspection, ... nanotechnology, ... applied research ... various responses are possible. 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) 4) Detection of interactions (analysis of power contribution rates)
