<<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 custom technology for ultrasonic systems that achieve ultrasonic control tailored to specific purposes using two types of ultrasonic transducers. System Overview 1: Two types of ultrasonic transducers (standard types: 28 kHz, 72 kHz) 2: Ultrasonic dedicated tank (standard type: internal dimensions: 500*310*340 mm) 3: Degassing and microbubble generation liquid circulation system 4: Optimization control system for ultrasonic output and liquid circulation volume *Features This is an effective device using a dedicated ultrasonic tank. Due to the efficient use of ultrasound, conventional tanks are insufficient in strength and durability. Cleaning, stirring, surface modification... depending on the target and purpose, the control combines two types of ultrasonic transducers. <Combination Examples> 1: 38 kHz, 70 kHz 2: 25 kHz, 38 kHz 3: 24 kHz, 68 kHz ... The key points are the accurate measurement, analysis, and confirmation of the ultrasonic oscillation frequency, and the realization of the ultrasonic propagation state based on the analysis and the purpose of ultrasonic use, involving the "liquid" and "liquid circulation" within the dedicated tank.

The Ultrasonic System Research Institute has developed "ultrasonic oscillation control (processing) technology" that utilizes the acoustic characteristics (vibration response characteristics and nonlinear phenomena) of objects (tools, target items, etc.) through a sound pressure measurement analysis device (ultrasonic tester) and a megahertz ultrasonic oscillation control probe. With the technology developed this time, it has become possible to control the vibration phenomena on target objects through "ultrasonic oscillation and output control," enabling dynamic control of ultrasonic vibrations (cleaning, processing, stirring, etc.) as a nonlinear effect of ultrasonic vibrations using the oscillation control probe. This is an effective ultrasonic utilization technology tailored to specific purposes for processing, cleaning, surface modification, and promoting chemical reactions. There are interactions with the acoustic characteristics of cutting tools (drills, reamers, cutters, knives, etc.) and the size and material of cutting oils, jigs, and target objects, making the analysis complex, but various applications based on sound pressure measurement analysis become possible.
