Original product: Ultrasonic control technology based on measurement, analysis, and evaluation of acoustic flow using an ultrasonic tester.

The Ultrasonic System Research Institute has developed a "flow-type ultrasonic (acoustic flow) control technology" that dynamically controls the propagation state of ultrasound (acoustic flow) through liquid circulation using a small pump. By using an ultrasonic tester to analyze the complex changes in flow and ultrasound, including the interactions of the water tank, liquid (microbubbles), and ultrasonic transducer, this system technology allows for the control of acoustic flow changes tailored to specific applications. In practical terms, it is a method for optimizing various interactions and vibration modes while considering the installation state of the liquid circulation device and the surface elastic waves of the target object, enabling ON/OFF control (or control of flow rate, flow velocity, etc.) of the current liquid circulation device. In particular, by utilizing the characteristics of the pump to alternately circulate liquid and gas, new effects of ultrasound and microbubbles are being realized. In nano-level applications, as a "flow-type ultrasonic system," efficient ultrasonic utilization has been achieved through "ultrasonic showers" that include frequency changes of over 300 megahertz.

- Technology combining sweep oscillation with ultrasonic probes and ultrasonic cleaners -

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology that enables the utilization of ultrasonic propagation states above 100 MHz by applying a function generator and ultrasonic probe to ultrasonic cleaners. This is a new application technology based on the measurement, analysis, evaluation, and techniques of ultrasonic propagation states, aimed at precision cleaning, processing, and stirring. By utilizing the acoustic properties (surface elastic waves) of various materials, it is possible to control ultrasonic stimulation above 100 MHz to the target object with an ultrasonic output of less than 20 W, even in a 1000-liter water tank. This was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic model of ultrasound. The key point is to confirm the ultrasonic propagation characteristics of the target object, which is important for setting the oscillation conditions of the ultrasonic oscillation control probe as an optimization of the system's vibration modes related to sweep oscillation and pulse oscillation, serving as a control method for the original nonlinear resonance phenomenon.

A technology has been developed to control the nonlinear phenomena of ultrasonic vibrations propagating to the target object based on classification techniques of ultrasonic waves and oscillation control.

We provide consulting services for the development of ultrasonic systems utilizing the following device. <<Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) 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 (microbubble) generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles (microbubbles), and when measuring the fine bubbles (microbubbles), the distribution of ultra-fine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled.
