Dynamic Control System of Ultrasonics

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 that applies the control of ultrasound and fine bubbles within a water tank to stimulate the surfaces of various materials and components with megahertz acoustic flow. In particular, the homogenization of surface residual stress has led to many achievements. << Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Bubbles of dissolved gas are produced due to cavitation. The above describes the state of the deaeration liquid circulation device. ... 6) In a stable and controllable state of ultrasound, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz (1-20 MHz) ultrasound. The optimization method for cavitation and acoustic flow achieves effective dynamic control of ultrasound by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasound. By organizing previous consulting responses, sound pressure measurements, and analyses, we have confirmed various know-how (specific methods related to individual objects and devices) and developed usage methods.
