Ultrasonic technology that controls the interaction of surface elastic waves.

***<Thinking Approach>*** The Ultrasonic System Research Institute has developed a model of the state, including phenomena related to the nonlinearity of ultrasound, as a Monoïd model in abstract mathematics (category theory). Based on this idea, we have developed a specific method for ultrasonic control as a spectral series of knot theory. The control method adapted to ultrasonic phenomena realizes dynamic changes in cavitation and acoustic flow by feedback analysis of sound pressure measurement data using an autoregressive model. From previous cases and achievements, it has been developed as a classification technique for nonlinear phenomena (harmonics, low-frequency reduction). Through a logical model, we dynamically control effective states of ultrasonic propagation (utilization) by classifying them into four types as follows: 1: Cavitation-dominant type 2: Acoustic flow-dominant type 3: Mixed type 4: Variable type The above logical classification is dynamically controlled by categorizing it into three variable type categories as a realistic response method based on the results of previous measurement data (ultrasonic phenomena that change over time).

The Ultrasonic System Research Institute has developed an effective stirring (emulsification, dispersion, grinding) technology utilizing the technique of controlling "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, achieved through the interaction of glass containers, ultrasound, and target objects, by controlling the oscillation of ultrasound. In particular, the dynamic characteristics of harmonics through acoustic flow control enable responses at the nano level. It has been applied and developed from examples of dispersing metal powders to nanosize. Through original measurement and analysis techniques of ultrasonic propagation states, we have confirmed the evaluation of acoustic flow and numerous know-how. 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)
