The Ultrasonic System Research Institute has developed an effective stirring (emulsification, dispersion, grinding) technology utilizing "technology to control nonlinear phenomena of ultrasound (acoustic flow)." This technology controls ultrasound (cavitation, acoustic flow) by utilizing (evaluating) the ultrasonic propagation characteristics (analysis results) of indirect containers through surface inspection, ultrasonic tanks, and other items. Furthermore, it realizes effective ultrasonic (cavitation, acoustic flow) propagation states tailored to the structure, material, and acoustic properties of specific target objects, by controlling the oscillation of ultrasound in accordance with the interactions between glass containers, ultrasound, and target objects. In particular, the dynamic characteristics of harmonics through acoustic flow control enable responses at the nano level.

Acoustic flow control technology using ultra-fine bubbles and megahertz ultrasound.

<<Deaeration Fine Bubble 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 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 generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles, and when measuring the fine bubbles, the distribution of ultrafine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In the state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz (1-20 MHz) ultrasonic waves. The method of controlling the sound pressure level is achieved by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasonic waves, setting and controlling it to an effective dynamic state.

Ultrasonic control technology based on the classification of nonlinear phenomena in which ultrasonic vibrations propagate.

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibration propagation by analyzing measurement data of ultrasonic propagation states using bispectral analysis. The method developed in this instance estimates the linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequencies (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to classify effective utilization methods into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type There are numerous successful cases of device development and control settings based on each of the above types. This technology will be offered as a consulting service. 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) 4) Detection of interactions (analysis of power contribution rates) Note: The following tools will be used for analysis.

Development of "Control Technology for Nonlinear Phenomena" Using a Small Pump

The Ultrasonic System Research Institute has developed "ultrasonic control technology" that dynamically controls nonlinear phenomena related to ultrasonic propagation by utilizing a small pump for liquid circulation. Nonlinear phenomena are evaluated through analysis using an ultrasonic tester. The complex changes in ultrasound (such as ultrasonic cleaners, ultrasonic probes, etc.) are confirmed through time-series data analysis of sound pressure from ultrasonic oscillation and reception, identifying various interactions. Based on the confirmation of these interactions, the oscillation control conditions using ultrasonic probes are optimized, achieving a dynamic ultrasonic control system tailored to specific objectives. In practical applications, such as ultrasonic cleaning, the ON/OFF control (or control of flow rate and velocity, etc.) of the current liquid circulation device is optimized by considering the ultrasonic propagation characteristics related to the installation state of the device and the surface elastic waves of the target object, including the output, oscillation frequency, and control conditions of the ultrasound. In particular, by utilizing the vibration characteristics of the pump to alternately circulate liquid and gas, new nonlinear effects of ultrasound and microbubbles are realized.

Ultrasonic oscillation (sweep oscillation) system for controlling nonlinear phenomena

The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface elastic waves based on the acoustic characteristics of original ultrasonic probes. The key point is the setting of sweep oscillation conditions using two ultrasonic probes (essentially, it cannot be controlled with just one probe for ultrasonic oscillation control. By combining the oscillation settings of the two probes, the occurrence of resonance phenomena and nonlinear phenomena can be controlled). Resonance phenomena and nonlinear phenomena can be controlled within a frequency range tailored to the intended use. In particular, when strong stimulation is required, this is achieved by utilizing low-frequency resonance phenomena (e.g., breaking glass). When high-frequency stimulation is needed, this is achieved by utilizing high-frequency nonlinear phenomena (e.g., 700 MHz stimulation).
