<<Analysis and Evaluation of Ultrasonic Sound Pressure Data>> 1) Regarding time series data, we will analyze and evaluate the statistical properties of the measurement data (stability and changes of ultrasonic waves) through feedback analysis using a multivariate autoregressive model. 2) The effects of the oscillation part due to ultrasonic oscillation will be analyzed and evaluated in terms of the response characteristics of ultrasonic vibration phenomena concerning the surface condition of the target object through impulse response characteristics and autocorrelation analysis. 3) The interaction between the oscillation and the target object (cleaning items, cleaning solutions, water tanks, etc.) will be evaluated through the analysis of power contribution rates. 4) Regarding the use of ultrasonic waves (cleaning, processing, stirring, etc.), we will analyze and evaluate the dynamic characteristics of ultrasonic waves based on the nonlinear phenomena (results of bispectral analysis) of the target object (propagation of surface elastic waves) or the ultrasonic waves propagating in the target liquid, which are the main factors of the ultrasonic effect. This analysis method is realized based on previous experience and achievements by adapting the dynamic characteristics of complex ultrasonic vibrations to the analysis methods of time series data. The following tool will be used for the analysis: "R," a free statistical processing language and environment.

The Ultrasonic System Research Institute has developed a tuning technology for piezoelectric elements that enables control over the linearity and non-linearity of surface elastic waves of objects ranging from 500 Hz to over 700 MHz. We manufacture and develop original ultrasonic oscillation control probes tailored to specific purposes. The key point is the optimization of propagation characteristics of surface elastic waves on ultrasonic elements according to their intended use. To achieve this, we conduct operational verification of the ultrasonic propagation characteristics of the original probes (sound pressure level, propagation frequency range, non-linearity, dynamic characteristics, etc.). By classifying ultrasonic probes based on their propagation characteristics, we determine the usable ranges of sound pressure level, frequency, and non-linearity.

The Ultrasonic System Research Institute, in collaboration with Fuji High Pressure Flexible Hose Co., Ltd., has applied for a patent regarding welding technology, utilizing an ultrasonic oscillation control probe for welding methods. Patent Application No. 2021-159990. Ultrasonic Probe: Overview Specifications - Measurement Range: 0.01 Hz to 200 MHz - Oscillation Range: 0.5 kHz to 25 MHz - Propagation Range: 0.5 kHz to over 700 MHz - Material: Stainless steel, steel materials, etc. - Oscillation Equipment: Example - Function Generator Oscillation Method Control settings are made corresponding to the acoustic characteristics of the target object. As a result, by controlling the original nonlinear resonance phenomenon, we achieve ultrasonic propagation states tailored to specific purposes. This is a new ultrasonic control technology based on the measurement, analysis, and evaluation of ultrasonic propagation states for precision cleaning, processing, stirring, inspection, and more. By utilizing the acoustic characteristics (surface elastic waves) of various materials, ultrasonic stimulation of structures and machinery weighing several tons can be controlled with an ultrasonic output of less than 20 W. 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.
