Vibration technology using megahertz ultrasound (improvement and adjustment of vibration modes)

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 has published measurement and analysis data on ultrasonic sound pressure using its original product: an ultrasonic tester. << Measurement and Analysis of Ultrasonic Sound Pressure >> 1) By using feedback analysis through a multivariate autoregressive model, we will examine and evaluate the stability and changes of ultrasonic waves (many ultrasonic cleaning devices have issues in this regard). 2) Through the analysis of impulse response characteristics and autocorrelation, we will conduct examinations and evaluations related to tanks, transducers, and tooling (these are the most important parameters in ultrasonic processing). 3) By analyzing power contribution rates, we will examine and evaluate the optimization of ultrasonic (frequency and output), tanks, and liquid circulation (this examination is crucial for mass production devices). 4) Through nonlinear (bispectral) analysis of other factors (propagation of surface elastic waves), we will conduct examinations and evaluations tailored to the target object for cleaning, stirring, dispersion, and modification (this is necessary for research and development of ultrasonic utilization methods, including applications in nanotechnology). This analysis method is realized by adapting the measurement data to the dynamic characteristics of complex ultrasonic vibrations.

The Ultrasonic System Research Institute has developed an ultrasonic oscillation control probe based on the acoustic properties of glass containers. By confirming the basic acoustic characteristics (response characteristics, propagation characteristics) depending on the shape and material of each container, it enables the desired ultrasonic propagation state through oscillation control (output, waveform, oscillation frequency, variations, etc.). The key point is to evaluate the dynamic vibration characteristics of the system based on the measurement and analysis of sound pressure data. We are establishing and confirming new evaluation criteria (parameters) that indicate the suitable state of ultrasound for the purpose. Note: - Nonlinear characteristics (dynamic characteristics of harmonics) - Response characteristics - Characteristics of fluctuations - Effects due to interactions By developing original measurement and analysis methods that consider the acoustic properties and surface elastic waves of the target object, referencing the ideas of statistical mathematics, we have developed a new technology regarding the relationships of various detailed effects related to vibration phenomena. The specific conditions for oscillation control are determined based on experimental confirmation, as they are also influenced by the characteristics of ultrasonic probes and oscillation equipment. As a result, there are increasing examples and achievements demonstrating that the new nonlinear parameters are very effective.
