The Ultrasonic System Research Institute has developed application technologies for ultrasonic systems using a quantum mechanics model based on "the mathematics of the shape and sound of drums" and "fundamental experiments and analyses on ultrasonic propagation phenomena." As a fundamental application of this technology, we have realized rational design techniques and standards for ultrasonic systems tailored to the purposes of ultrasonic utilization. The technology developed this time was achieved through an abstract algebra model that adapts the oscillation and propagation states of ultrasound to the quantum mechanical wave function. Unlike previous development methods, we determine the control conditions of the system by interpreting the energy levels (corresponding to the order of harmonics) of the ultrasonic propagation state of the target object as perturbations (results from bispectral analysis) of nonlinear phenomena and sound (low-frequency vibrations). Furthermore, through the "evaluation technology for ultrasonic devices" at the Ultrasonic System Research Institute, we have confirmed specific effects of this method. As application examples, there has been an increase in proposals for "ultrasonic welding," "ultrasonic processing," and "ultrasonic plating," among others.

- Technology for controlling nonlinear ultrasonic phenomena: Nanolevel stirring, emulsification, dispersion, and grinding technology - The Ultrasonic System Research Institute has developed effective stirring (emulsification, dispersion, grinding) technology utilizing the technology for controlling nonlinear ultrasonic phenomena (acoustic flow). This technology controls ultrasonic (cavitation, acoustic flow) by utilizing (evaluating) the ultrasonic propagation characteristics (analysis results) of indirect containers, ultrasonic tanks, and other equipment through surface inspection. Furthermore, it realizes effective ultrasonic (cavitation, acoustic flow) propagation states tailored to the structure, material, and acoustic properties of specific target objects, in accordance with the interactions between glass containers, ultrasonic waves, and target objects, through ultrasonic oscillation control. In particular, the dynamic characteristics of harmonics achieved through acoustic flow control enable responses at the nanolevel. It has been developed from applications involving the dispersion of metal powders to nanosize. By employing control technologies for standing waves and cavitation in relation to ultrasonic waves, as well as propagation control technologies for indirect containers, appropriate stirring is performed using cavitation and acoustic flow.
