Manufacturing technology for ultrasonic oscillation control probes (consulting support)

The Ultrasonic System Research Institute has developed a liquid circulation technology for ultrasonic cleaners that utilizes the "Constructal Law" related to flow and shape (control of nonlinear phenomena). This was developed with inspiration from observations of river flows, as shown in the attached photo. Regarding the use of ultrasound, we believe that through our experience in observing flow, we can intuitively grasp acoustic flow (a nonlinear phenomenon of ultrasound). Acoustic flow <General Concept> When finite amplitude waves propagate through a gas or liquid, acoustic flow occurs. Acoustic flow is a unidirectional steady flow of matter that arises either as a result of viscous losses from wave pulses in a free inhomogeneous field, or in the vicinity of obstacles (cleaning objects, fixtures, liquid circulation) within an acoustic field, or near vibrating bodies due to inertial losses. Using the above as a reference and hint, we organize the technology for measuring, analyzing, evaluating, and utilizing (controlling) "nonlinear phenomena" in ultrasonic propagation phenomena through the "Constructal Law," which improves flow, thereby consolidating it into ultrasonic technology.

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.).

Basic Experiments on "Control Technology of Acoustic Flow" (Measurement, Analysis, and Control Techniques Using Ultrasonic Testers) The Ultrasonic System Research Institute has developed "Control Technology of Acoustic Flow" suitable for ultrasonic applications such as cleaning, processing, stirring, modification, and chemical reactions, effectively utilizing the acoustic characteristics and vibration modes of tools and flowing liquids according to specific purposes through ultrasonic testers. **Acoustic Flow** General Concept When a finite amplitude wave propagates through a gas or liquid, acoustic flow is generated. Acoustic flow occurs as a result of viscous losses from wave pulses, either in a free heterogeneous field or near obstacles in the sound field (such as cleaning objects, jigs, or liquid circulation) or near vibrating bodies, resulting in a unidirectional steady flow of matter due to inertial losses. Acoustic flow is an important enhancement factor in the majority of ultrasonic processing processes, purification, drying, emulsification, combustion, extraction, etc., significantly promoting heat exchange and material exchange within the medium. The effects of acoustic flow in processing operations are determined by their velocity and dimensional factors.
