Megahertz ultrasonic system (cleaning, stirring, processing, surface treatment, etc.)

<< 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 gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the bubble size of the dissolved gas 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 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 amount of ultra-fine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In a state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of ultrasonic waves in the megahertz range (1-20 MHz).

The Ultrasonic System Research Institute has developed ultrasonic system technology that enables the control of ultrasonic propagation states above 1-900 MHz by installing a megahertz ultrasonic oscillation control probe in resin containers. By measuring, analyzing, evaluating, and technically assessing the ultrasonic propagation characteristics of containers and mounting components, effective ultrasonic irradiation for precision cleaning, processing, stirring, welding, and plating can be achieved. This represents a new application technology for ultrasound. Utilizing various acoustic properties (surface elastic waves) based on the structure, shape, and manufacturing methods of various materials, ultrasonic stimulation can be controlled for objects weighing several tons even in a 1000-liter water tank with an ultrasonic output of less than 20W. 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. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in self-correlation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response) 4) Detection of interactions (analysis of power contribution rates)

The Ultrasonic System Research Institute has developed a technology to optimize ultrasonic propagation systems that can control resonance phenomena and nonlinear phenomena based on various analysis results of ultrasonic propagation states using an original ultrasonic system (sound pressure measurement analysis and oscillation control). Furthermore, we have advanced the above technology and developed optimization and evaluation techniques related to water tanks, ultrasonic waves, and liquid circulation. In contrast to previous control technologies, this technology utilizes new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools, to achieve dynamic ultrasonic propagation states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.). This is a method and technology that can be applied immediately, and we offer it as consulting services (with increasing achievements in ultrasonic processing, precision cleaning at the nano level, stirring, etc.). Note: The original technology product (ultrasonic sound pressure measurement analysis system) measures, analyzes, and evaluates dynamic changes in the propagation state of water tanks, transducers, target objects, and tools, among others. (Parameters: power spectrum, autocorrelation, response characteristics, etc.)

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 purposes. With this technology, when using multiple ultrasonic transducers of different frequencies, it becomes possible to set (manage) the propagation state of ultrasound influenced by harmonics. Therefore, it enables the realization of 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 liquid circulation control, dynamic control becomes possible to change the effects of cavitation and acceleration (acoustic flow) according to the intended purpose. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response characteristics) 4) Detection of interactions (analysis of power contribution rates)
