－－Abstract Algebra Model and Ultrasonic Experimentation and Examination Cycle－－ (Optimization Techniques for Resonance Phenomena and Nonlinear Phenomena) The Ultrasonic System Research Institute has developed ultrasonic <dynamic control> technology that optimizes the interaction of ultrasonic vibrations based on various analytical results of ultrasonic propagation states obtained through an original ultrasonic system (sound pressure measurement analysis and oscillation control) using an abstract algebra model. Note: Control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. Compared to previous control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we are proposing and responding to it as a consulting service (there is an increasing track record in precision cleaning, stirring, and processing at the nano level). Note: Parameters: Power spectrum, autocorrelation, bispectrum, power contribution ratio, impulse response characteristics, and others.

The Ultrasonic System Research Institute is applying and developing manufacturing technology for original ultrasonic probes. We have developed technology to control the nonlinear vibration phenomena of surface elastic waves through oscillation control techniques based on the acoustic characteristics of the probes, and we provide consulting services for various ultrasonic utilization technologies. The key point is the optimization of the ultrasonic propagation section (Note). Note: By relaxing and homogenizing surface residual stress, stable ultrasonic oscillation control becomes possible. Setting technology for oscillation control conditions: 1) Setting of oscillation waveforms corresponding to the vibration modes of devices and equipment. 2) Setting of sweep conditions corresponding to the vibration modes of devices and equipment. 3) Setting of output levels corresponding to the vibration modes of devices and equipment. To achieve this, it is important to evaluate the characteristics related to ultrasonic propagation conditions through operational verification of the ultrasonic propagation characteristics of the original probe (sound pressure level, frequency range, nonlinearity, dynamic characteristics, etc.). Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation). 2) Detection of nonlinear phenomena (changes in bispectrum). 3) Detection of response characteristics (impulse response). 4) Detection of interactions (power contribution rate).
