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.).

Ultrasonic oscillation control technology for controlling nonlinear vibration phenomena

This is a control technology based on measurement, analysis, and evaluation techniques of ultrasonic propagation states, featuring an original nonlinear resonance phenomenon (Note 1). It represents a new application technology for precision cleaning, processing, stirring, inspection, and surface treatment. Note 1: Original Nonlinear Resonance Phenomenon This phenomenon occurs due to the generation of harmonics through original oscillation control, which achieves high amplitude ultrasonic vibrations through resonance phenomena. To efficiently utilize the acoustic properties (surface elastic waves) of various materials, the relaxation treatment of residual stress distribution on surfaces can be easily realized. From an engineering (experimental and technical) perspective on elastic waves and the ultrasonic model of abstract algebra, the original oscillation control method (Note 2) has been developed as an application method for nonlinear phenomena. Note 2: Original Oscillation Control Method Two types of ultrasonic oscillation are performed: one is sweep oscillation control, and the other is pulse oscillation control. Detailed settings are based on the purpose, target object, and tooling, and are configured according to a logical model from the vibration system as a whole.

Application technology for ultrasonic sound pressure measurement, analysis, control, and evaluation systems.

The Ultrasonic System Research Institute has developed technology to control resonance and nonlinear phenomena in the propagation state of surface acoustic waves through the control of ultrasonic oscillation, using a combination of low and high frequencies. By utilizing new ultrasonic propagation materials (such as stainless steel wire and titanium straws), efficient ultrasonic applications tailored to specific purposes become possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this system technology controls the complex changes in surface acoustic waves according to the intended use. Practically, by using multiple (two types of) ultrasonic probes to generate multiple (two types of) oscillations (sweep oscillation and pulse oscillation), complex vibration phenomena (original nonlinear resonance phenomena) are created, achieving high-frequency propagation states at high sound pressure or low-frequency propagation states tailored to the desired natural frequency. In particular, by optimizing the vibration characteristics of tanks and pumps with megahertz ultrasound, efficient ultrasonic control is realized (propagating through 3000 liters of cleaning solution at a 30W output).

Ultrasonic cleaning system that achieves ultrasonic control tailored to the purpose.

This is an effective device using a dedicated ultrasonic tank (original manufacturing method). Due to the high efficiency of ultrasonic utilization, standard tanks lack sufficient strength and durability. Depending on the target and purpose, multiple ultrasonic waves and a degassing fine bubble generation liquid circulation device are controlled based on sound pressure measurement analysis for cleaning, stirring, and surface modification. We propose various combinations and usage (control) methods. The key point is to achieve an ultrasonic propagation state tailored to the target, focusing on the "dissolved oxygen concentration distribution" and "liquid circulation" within the dedicated tank. << Degassing Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the degassing liquid circulation device. 3) As the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) smaller than 20μ are generated. The above describes the state of the degassing microbubble generation liquid circulation device.
