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.

Application of a new surface inspection technology using megahertz ultrasonic oscillation.

The Ultrasonic System Research Institute has developed a new surface inspection technology using megahertz ultrasonic oscillation based on its track record of analyzing ultrasonic data propagating on the surface of target objects. Using this technology, we will evaluate the ultrasonic propagation characteristics of the items to be cleaned and compile a report proposing effective control, frequency, and output levels for ultrasonic cleaning machines. This method applies measurement and analysis techniques for "sound pressure and vibration" by controlling the oscillation of the ultrasonic probe. By using an original ultrasonic probe tailored to the vibration modes propagating on the surface of the target object, we can confirm the propagation state of ultrasonic waves in narrow grooves and edge areas. Furthermore, through original oscillation control, we will measure and analyze the dynamic characteristics of low-frequency propagation properties and the generation state of harmonics due to nonlinearity. This is an application of the new ultrasonic oscillation control technology.
