Ultrasound system development technology based on sound pressure data analysis.

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 developed a technology to adjust the ultrasonic propagation characteristics of ultrasonic elements (piezoelectric elements) based on measurement, analysis, and evaluation results regarding the propagation state of ultrasound, utilizing ultrasonic systems (sound pressure measurement, oscillation control). To utilize the surface acoustic waves of ultrasonic elements (piezoelectric elements) according to specific purposes, special surface treatments are applied to the element's surface. It allows for adjustments to the sound pressure level and frequency range of the propagating ultrasound. By achieving dynamic ultrasonic propagation control through the combination of ultrasound (oscillation control) and surface acoustic waves, it has evolved into an adjustment technology based on the characteristics derived from the analysis of sound pressure data. The key point is the optimization of oscillation conditions (waveform, output, frequency, variations, etc.) to enable efficient control of nonlinear phenomena caused by surface acoustic waves. As specific technologies mentioned above, we provide consulting services for system technologies that control nonlinear phenomena (bi-spectra) resulting from the interaction of ultrasound with tanks and tools, tailored to specific purposes (cleaning, stirring, processing, welding, surface treatment, stress relief treatment, inspection, etc.).

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound using two function generators. This technology enables the control of ultrasonic nonlinear phenomena and resonance phenomena through different types of (sweep) oscillations using two different waveforms. By applying this technology, we are developing practical methods to alleviate residual stress on component surfaces and various application technologies, and we provide consulting services. Example 1: 1) Sweep oscillation control from 1.0 MHz to 15 MHz 2) Sweep oscillation control from 0.6 MHz to 5 MHz 3) Precision cleaning at the nano level using a 42 kHz 35W ultrasonic cleaner Example 2: 1) Sweep oscillation control from 3 MHz to 20 MHz 2) Sweep oscillation control from 60 kHz to 3 MHz 3) Nano dispersion treatment of metal powders using a 42 kHz 35W ultrasonic cleaner Standard Settings: 1) Sweep oscillation control from 3 MHz to 20 MHz 2) Sweep oscillation control from 60 kHz to 13 MHz 3) Dynamic control of ultrasound using a 42 kHz 35W ultrasonic cleaner

The Ultrasonic System Research Institute has developed a technology to optimize ultrasonic propagation systems that can control resonance phenomena and nonlinear phenomena based on various analysis results of ultrasonic propagation states using an original ultrasonic system (sound pressure measurement analysis and oscillation control). Furthermore, we have advanced the above technology and developed optimization and evaluation techniques related to water tanks, ultrasonic waves, and liquid circulation. In contrast to previous control technologies, this technology utilizes new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools, to achieve dynamic ultrasonic propagation states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.). This is a method and technology that can be applied immediately, and we offer it as consulting services (with increasing achievements in ultrasonic processing, precision cleaning at the nano level, stirring, etc.). Note: The original technology product (ultrasonic sound pressure measurement analysis system) measures, analyzes, and evaluates dynamic changes in the propagation state of water tanks, transducers, target objects, and tools, among others.
