Development technology for ultrasonic probes and ultrasonic oscillation control systems - Aging treatment of piezoelectric elements.

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 performed on the element surface. It allows for adjustments to the sound pressure level and frequency range of the propagating ultrasound. By realizing 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.) that enables 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-spectral) 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.).

Application of sweep oscillation control technology to control nonlinear phenomena of ultrasound.

The Ultrasonic System Research Institute has developed ultrasonic system technology that enables control of ultrasonic propagation states above 1-700 MHz by utilizing a megahertz ultrasonic oscillation control probe for ultrasonic equipment. This is a new application technology based on the measurement, analysis, evaluation, and techniques of ultrasonic propagation states, applicable to precision cleaning, processing, stirring, welding, plating, and more. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled for several tons of target objects even in a 1000-liter water tank with ultrasonic output below 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic wave phenomena and an abstract algebraic ultrasonic model. The key point is the use of tools (elastic bodies: metal, glass, resin). By confirming the ultrasonic propagation characteristics depending on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This phenomenon occurs due to the generation of harmonics resulting from original oscillation control, realized at high amplitudes through resonance phenomena, leading to ultrasonic vibration resonance phenomena.
