Megahertz ultrasonic cleaner (consulting support for utilization technology)

The Ultrasonic System Research Institute has developed a megahertz ultrasonic oscillation control probe that enables the utilization of ultrasonic propagation states from 1 to over 900 MHz by combining it with a function generator for controlling ultrasonic propagation states. This is a new application technology for precision cleaning, processing, stirring, and inspection based on measurement, analysis, and evaluation techniques of ultrasonic propagation states. By utilizing the acoustic properties (surface elastic waves) of various materials, it is possible to control ultrasonic stimulation to several tons of structures and machine tools in a 3000-liter water tank with an ultrasonic output of less than 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model. The key point is the utilization method of surface elastic waves. By confirming the ultrasonic propagation characteristics depending on the conditions of the target object (Note 1), it is important to address it as an original nonlinear resonance phenomenon. Note 1: Ultrasonic propagation characteristics 1) Detection of vibration modes (changes in self-correlation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics 4) Detection of interactions

Nonlinear Vibration Control of Ultrasound By addressing the low-frequency vibration energy through innovative methods included in nonlinear vibrations (oscillation control, tapping, etc.), we have developed a new approach that allows high-frequency ultrasound to propagate efficiently. We are confirming various effects using low-output (below 10W) ultrasound. From various implementation results (note), we propose and implement a wide range of responses through various combinations. Note: 1) Nano-level emulsification and dispersion 2) Ultrasonic cleaning using solvents 3) Control of ultrasonic atomization size 4) Experiments on chemical reaction control 5) Stirring, emulsification, and dispersion of nano-level catalysts 6) Application to uniform particle production 7) Surface treatment of metals 8) Megahertz ultrasonic propagation 9) Precision cleaning 10) Uniformization of aluminum die casting 11) Uniformization of various solvents 12) Others... This technology (detailed know-how, etc.) is offered as a consulting service.

The Ultrasonic System Research Institute will celebrate its 15th anniversary on August 7, 2024. We would like to continue to cherish our entrepreneurial philosophy. Ultrasonic System Research Institute <Philosophy> "The deepest philosophy is born by grasping what our most ordinary daily life is most profoundly. Ultimately, scholarship is for LIFE. LIFE is the most important thing. Scholarship without LIFE is useless." - Kitaro Nishida Based on deep philosophy, we aim to promote the effective use of ultrasound through experiments (observing objects as objects). <<Ultrasonic System Research Institute>> August 7, 2024 Ultrasonic System Research Institute Representative: Kazuyuki Saiki Propagation characteristics of ultrasound: 1) Detection of vibration modes (changes in autocorrelation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response) 4) Detection of interactions (analysis of power contribution rates)

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.
