The Ultrasonic System Research Institute utilizes a <degasification and microbubble generation liquid circulation system> to achieve effective ultrasonic control tailored to specific purposes. Explanation of Ultrasonic Liquid Circulation Technology 1) We use a dedicated ultrasonic tank (original manufacturing method). 2) The installation of the tank involves: 1: Using specialized materials. 2: Optimizing the natural vibration, ultrasonic frequency, and output. 3) The ultrasonic transducer is installed using specialized materials. (These materials can limit the utilization states of standing waves, cavitation, and acoustic flow.) 4) We use a degasification and microbubble generation device. (The standard dissolved oxygen concentration is 5-6 mg/l.) 5) The tank and ultrasonic transducer undergo surface modification. With the above settings and the diffusibility of microbubbles, a uniform cleaning liquid state is achieved. Ultrasonic waves propagate through the uniform liquid, generating a stable ultrasonic state. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). The operation control of the ultrasonic device, degasification device, liquid circulation pump, etc., is our expertise.

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 new component inspection technology using megahertz ultrasonic oscillation based on its track record of analyzing ultrasonic data propagating on the surface of objects. This method applies the measurement and analysis technology of "sound pressure and vibration" through the control of original ultrasonic probe oscillation. We provide consulting and explanations of ultrasonic evaluation technology through the development of ultrasonic probes tailored to the purpose (vibration modes propagating on the surface of objects). This is an application of new ultrasonic oscillation control technology. By utilizing nonlinear phenomena related to megahertz ultrasonic propagation states that match the acoustic characteristics of the target object, it is possible to detect new features regarding the surface condition of the object. In particular, this fundamental technology serves as a new evaluation parameter for ultrasonic vibrations, utilized in surface inspection of substrate components and pre-evaluation of precision cleaning parts, leveraging the response characteristics derived from combinations of oscillation and reception. By measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves related to the propagation phenomena of surface elastic waves, we have enabled effective use tailored to the purpose (evaluation) through the construction and modification of logical models.

The Ultrasonic System Research Institute has developed a technology to utilize (control) "nonlinear phenomena related to the generation of harmonics in ultrasound" by analyzing ultrasonic sound pressure measurement data (bispectral analysis, etc.) according to specific objectives. With this technology, when using multiple ultrasonic transducers with different frequencies, it becomes possible to set (manage) the propagation state of ultrasound influenced by harmonics. Therefore, it is possible to achieve appropriate or effective combinations of frequencies. This is very effective as it allows for the detection and confirmation of effective propagation states for cleaning, surface modification, and the promotion of chemical reactions. Furthermore, by combining the control of standing waves with the control of liquid circulation, dynamic control becomes possible to change the effects of cavitation and acceleration (acoustic flow) according to specific objectives. Through original measurement and analysis technology for ultrasonic propagation states, we have confirmed numerous effective cases related to the surface conditions of various components, including cleaning, stirring, surface modification, and chemical reactions.
