The Ultrasonic System Research Institute conducts consulting related to ultrasonic applications using 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 from ultrasonic testers chronologically, we establish and verify new evaluation criteria (parameters) that indicate the appropriate ultrasonic state for the intended purpose. Note: - Nonlinear characteristics (dynamic characteristics of acoustic flow) - Response characteristics - Fluctuation characteristics - Effects due to interactions By developing original measurement and analysis methods that consider the acoustic properties of the target object and surface elastic waves, we deepen our understanding of the relationships between various effects related to vibration phenomena, referencing statistical mathematical concepts. As a result, there is an increasing number of cases demonstrating that new nonlinear parameters are very effective regarding the propagation state of ultrasound and the surface of the target object. In particular, evaluation cases related to cleaning, processing, and surface treatment effects lead to successful control and improvement based on favorable confirmations.

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 (Location: Hachioji City, Tokyo) has developed ultrasonic oscillation control technology that enables the use of ultrasonic propagation states above 200 MHz with oscillation below 20 MHz by utilizing a function generator and an original ultrasonic oscillation probe in relation to ultrasonic cleaners. This is a new application technology for precision cleaning, processing, and stirring based on the measurement, analysis, evaluation, and technology of ultrasonic propagation states. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation to the target object can be controlled with an ultrasonic output of less than 20W, even in a 5000-liter water tank. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model. The key point is the appropriate use of the water tank, target object, and tools. By confirming the propagation characteristics of ultrasonic waves based on the conditions of the target object, it is important to optimize the oscillation conditions of megahertz ultrasonic waves as an original nonlinear resonance phenomenon.
