A technology that utilizes dynamic nonlinear phenomena of ultrasound by striking.

A technology for alleviating and equalizing the surface residual stress of ultrasonic transducers using an ultrasonic and fine bubble generation liquid circulation system.

The Ultrasonic System Research Institute has published a technology that applies measurement, analysis, and control techniques related to the propagation state of ultrasound to relax the surface residual stress of ultrasonic transducers using an ultrasonic and fine bubble generation liquid circulation system. This technology for relaxing surface residual stress enables the improvement of fatigue strength against metal fatigue. In particular, by considering the guided waves (surface elastic waves) of the target object in the propagation state of ultrasound, we have developed a method to achieve effective ultrasonic irradiation conditions through the setting, tooling, and control. We have confirmed a wide range of effects on various types of metal parts, resin parts, and powder materials. This technology will be offered as a consulting service. This is a new surface treatment technology using ultrasound, which, including the general effects based on acoustic properties, can be utilized and developed as a distinctive operational technology for the development of new materials, stirring, dispersion, cleaning, and chemical reaction experiments.

Ultrasonic Treatment 1: "Nanopowdering" Ultrasonic Treatment 2: "Liquid Homogenization and Flowability Improvement" The Ultrasonic System Research Institute has developed a "technology for liquid homogenization and flowability improvement using ultrasonic control of nonlinear phenomena (acoustic flow)." This technology utilizes (evaluates) the ultrasonic propagation characteristics (analysis results) of indirect containers, ultrasonic tanks, and other items through surface inspection to control ultrasonic (cavitation and acoustic flow). Furthermore, it achieves effective ultrasonic (cavitation and acoustic flow) propagation states tailored to the structure, material, and acoustic properties of specific target objects, by controlling the ultrasonic oscillation in accordance with the interactions between glass containers, ultrasonic waves, and target objects. In particular, the dynamic characteristics of harmonics through acoustic flow control enable responses at the nanoscale.

Application technology of <measurement, analysis, and control> using ultrasonic testers.

The Ultrasonic System Research Institute has developed "ultrasonic propagation control technology" using titanium straws based on the classification of cavitation and acoustic flow. This system technology controls changes in acoustic flow according to its intended use by analyzing the complex variations of flow, ultrasound, and fine bubbles through sound pressure measurement analysis that includes various interactions. Practically, it is a method to optimize ON/OFF control (or control of flow rate, flow velocity, etc.) for a degassing fine bubble generation liquid circulation device for showers against various interactions and vibration modes. In particular, by controlling the acoustic characteristics of titanium straws and the oscillation control of megahertz ultrasound, it achieves the effects of a new dynamic ultrasonic control technology by controlling the original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This phenomenon occurs when the generation of harmonics caused by original oscillation control is realized at high amplitudes through resonance phenomena, resulting in ultrasonic vibration resonance. Ultrasonic propagation characteristics: 1) Vibration modes 2) Nonlinear phenomena 3) Response characteristics 4) Interactions

Surface treatment using ultrasonic surface elastic waves.

The Ultrasonic System Research Institute has developed (and published) methods to apply technologies using ultrasound and microbubbles for: 1) Relaxing residual stress near surfaces 2) Removing microscopic burrs in ultrasonic beauty devices. Through the technology that relaxes residual stress using ultrasound and microbubbles, we have experienced improvements in fatigue strength against metal fatigue, which leads to the uniformity of the surface of ultrasonic beauty devices and the efficiency of ultrasonic oscillation and propagation. This significantly changes the usage conditions of ultrasound (the dynamic characteristics of propagation frequency). In particular, the sound pressure level and propagation frequency of ultrasound vary greatly depending on the edge treatment of metal components that come into contact with the skin. By performing uniformity treatment, stable reproducibility and extended lifespan can be achieved. (This has been developed from achievements in ultrasonic cleaning.) We offer this technology as a consulting service.

Technology for controlling nonlinear phenomena of ultrasound (acoustic flow)

The Ultrasonic System Research Institute has developed ultrasonic cleaning technology that enables control of acoustic flow (ultrasonic propagation state) in the range of 1-100 MHz by utilizing a megahertz ultrasonic oscillation control probe for ultrasonic cleaners. This is a new application technology for precision cleaning, processing, and stirring based on the measurement, analysis, evaluation, and technology of ultrasonic propagation states. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled even in a 1000-liter water tank with an ultrasonic output of less than 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model. The key point is the use of tools (elastic bodies: metals, glass, plastics). By confirming the propagation characteristics of ultrasonic waves based on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon. We believe that this technology can be applied in various fields and are implementing proposals in various consulting services.
