Control technology for megahertz ultrasound applied using Shannon's juggling theorem.

The Ultrasonic System Research Institute is applying and developing manufacturing technology for original ultrasonic probes. We have developed technology to optimize the nonlinear vibration phenomenon of surface acoustic waves through oscillation control technology based on the acoustic characteristics of the probes, and we provide consulting services for various ultrasonic utilization technologies. Note 1: Original nonlinear resonance phenomenon The resonance phenomenon of ultrasonic vibrations occurs due to the generation of harmonics resulting from original oscillation control of ultrasonic waves, which achieves high amplitude through resonance. The key point is the optimization of the ultrasonic propagation section. Note 2: By relaxing and homogenizing surface residual stress, stable ultrasonic oscillation control becomes possible. Technology for setting oscillation control conditions: 1) Setting of oscillation waveforms corresponding to the ultrasonic propagation characteristics of the device/equipment. 2) Setting of sweep conditions corresponding to the ultrasonic propagation characteristics of the device/equipment. 3) Setting of output levels corresponding to the ultrasonic propagation characteristics of the device/equipment. 4) Adjustment of various interactions corresponding to the ultrasonic propagation characteristics of the device/equipment.

Propagation Phenomena of Ultrasonic Vibration 1-3. Fine Bubbles (Microbubbles) *Properties of Microbubbles* 1) Bubbles of about 10μm rise slowly over approximately 3 hours to a height of 1m. 2) The generated bubbles exist independently without coalescing, resulting in excellent dispersion. 3) They have the property of slowly rising in water and adsorbing tiny debris to bring it to the surface. ... 13) The negative potential depends on the pH of the water. 14) Microbubbles have excellent scattering characteristics for ultrasound. 15) Microbubbles collapse as a resonance phenomenon when exposed to ultrasonic irradiation. These properties are expected to be further elucidated in the future, but currently contain many unknown aspects.

Acoustic flow <general concept> When a finite amplitude wave propagates through a gas or liquid, acoustic flow occurs. Acoustic flow is a unidirectional steady flow of matter that arises as a result of viscous losses from wave pulses, either in a free inhomogeneous field or in the vicinity of obstacles (cleaning objects, jigs, liquid circulation) within an acoustic field, or near vibrating bodies due to inertial losses.
