Publication of relaxation technology for surface residual stress of ultrasonic transducers.

Relaxation and uniform treatment of surface residual stress using ultra-fine bubbles and megahertz acoustic flow control.

<<Deaeration Fine Bubble Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the size of the bubbles formed by cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles, and when measuring the fine bubbles, the distribution of ultrafine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In the state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz ultrasonic waves. The method of controlling the sound pressure level is achieved by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasonic waves, setting and controlling it to an effective dynamic state.

Application of technology to analyze and evaluate the dynamic characteristics of ultrasound.

The Ultrasonic System Research Institute has developed a method (system) for the analysis and evaluation of ultrasound, applying "measurement, analysis, and control" technology related to the nonlinearity of ultrasound. We are providing on-site support for the additional installation of a degassing fine bubble generation liquid circulation system utilizing this technology. To utilize (control) the complex and changing conditions of ultrasound in a stable manner, we offer on-site services to add and confirm sound pressure measurements for the degassing fine bubble generation liquid circulation system in specific tanks present at the site. **Explanation of Degassing Fine Bubble Generation Liquid Circulation Technology** By ensuring appropriate liquid circulation and the diffusibility of fine bubbles, a uniform state of cleaning liquid is achieved. Ultrasound propagates through the uniform liquid, generating a stable state of ultrasound. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). This involves achieving a uniform sound pressure distribution throughout the tank, optimizing ultrasound, liquid circulation pumps, fine bubbles, etc. The operational control becomes the know-how for individual tanks.
