Technology for using ultrasonic cleaners through sweep oscillation.

－－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 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.

The Ultrasonic System Research Institute has developed (and published) methods to apply technologies using ultrasound and fine bubbles/microbubbles to ultrasonic beauty devices for: 1) Techniques to relax and homogenize residual stress on component surfaces 2) Techniques to remove microscopic burrs Through the technology that relaxes surface residual stress using ultrasound and microbubbles, improvements in fatigue strength against metal fatigue can be achieved, leading to the homogenization of the ultrasonic beauty device surface and the efficiency of ultrasonic oscillation and propagation. We have experienced significant changes in the usage conditions of ultrasound (dynamic characteristics of propagation frequency). In particular, the ultrasonic sound pressure level and propagation frequency vary greatly depending on the edge treatment of the metal parts that come into contact with the skin. By performing homogenization treatment, stable reproducibility and long lifespan can be realized. (This has been developed from achievements in ultrasonic cleaning.)
