Ultrasonic device: Surface modification of the tank surface (relaxation and uniformization of surface residual stress) technology - Dynamic control technology of ultrasound -

A completely new vibration measurement technology using original products (ultrasonic testers).

The Ultrasonic System Research Institute has developed a completely new <vibration measurement technology> using its original product (ultrasonic tester). The ultrasonic sound pressure measurement analysis technology developed so far applies the "measurement, analysis, and control" technology related to the nonlinear phenomena of ultrasound. From the accumulation of data measuring, analyzing, and evaluating the dynamic characteristics of ultrasound propagating on surfaces, we have developed technology that can <measure, analyze, and evaluate> vibration states from low frequencies (0.001 Hz) to high frequencies (700 MHz). Regarding vibrations and noise from buildings and roads, equipment, devices, walls, piping, desks, handrails... as well as the vibrations at the moment of metal melting during welding and instantaneous vibrations during machining, we have made it possible to respond with vibration control and management based on the measurement and analysis of new vibration phenomena. This is a new method and technology, and various application cases have developed from the analysis results so far. In particular, continuous data collection for a standard measurement time of 72 hours is possible, allowing measurement of low-frequency vibrations and irregularly fluctuating vibrations (maximum measurement can be overwritten over a continuous period of 14 days).

Application of technology to analyze and evaluate the dynamic characteristics of ultrasound.

The Ultrasonic System Research Institute has developed a method (system) for the analysis and evaluation of ultrasound, applying "measurement, analysis, and control" technology related to the nonlinearity of ultrasound. We are providing on-site support for the additional installation of a degassing fine bubble generation liquid circulation system utilizing this technology. To utilize (control) the complex and changing conditions of ultrasound in a stable manner, we offer on-site services to add and confirm sound pressure measurements for the degassing fine bubble generation liquid circulation system in specific tanks present at the site. **Explanation of Degassing Fine Bubble Generation Liquid Circulation Technology** By ensuring appropriate liquid circulation and the diffusibility of fine bubbles, a uniform state of cleaning liquid is achieved. Ultrasound propagates through the uniform liquid, generating a stable state of ultrasound. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). This involves achieving a uniform sound pressure distribution throughout the tank, optimizing ultrasound, liquid circulation pumps, fine bubbles, etc. The operational control becomes the know-how for individual tanks.

Application technologies of measurement, analysis, and control using ultrasonic testers - sweep oscillation technology and pulse oscillation technology.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing two function generators. Through oscillation with two different waveforms (sweep), we have realized a technology to control the nonlinear phenomena of ultrasound. Note: Nonlinear (resonance) phenomena By generating (10th order and higher) harmonics through original oscillation control and resonating with low-frequency vibration phenomena, we have achieved the generation of high-amplitude harmonics, which is the nonlinear (resonance) phenomenon of ultrasonic vibrations. By optimizing the ultrasonic propagation characteristics of various materials according to their intended use, efficient ultrasonic oscillation control becomes possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this is a system technology that controls the dynamic changes of surface elastic waves according to the intended purpose.

Ultrasonic cleaning system that achieves ultrasonic control tailored to the purpose.

This is an effective device using a dedicated ultrasonic tank (original manufacturing method). Due to the high efficiency of ultrasonic utilization, standard tanks lack sufficient strength and durability. Depending on the target and purpose, multiple ultrasonic waves and a degassing fine bubble generation liquid circulation device are controlled based on sound pressure measurement analysis for cleaning, stirring, and surface modification. We propose various combinations and usage (control) methods. The key point is to achieve an ultrasonic propagation state tailored to the target, focusing on the "dissolved oxygen concentration distribution" and "liquid circulation" within the dedicated tank. << Degassing Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the degassing liquid circulation device. 3) As the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) smaller than 20μ are generated. The above describes the state of the degassing microbubble generation liquid circulation device.

Combination technology of function generator and ultrasonic probe

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology that enables the utilization of ultrasonic propagation states above 100 MHz by applying a function generator and ultrasonic probe to 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, it is possible to control ultrasonic stimulation above 100 MHz to the target object with an ultrasonic output of less than 20 W, even in a 1000-liter water tank. This 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 to confirm the ultrasonic propagation characteristics of the target object, and it is important to set the oscillation conditions of the function generator as a control method for the original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This refers to the resonance phenomenon of ultrasonic vibrations that occurs when the generation of harmonics caused by original oscillation control is realized at a high amplitude due to resonance phenomena.

Surface modification treatment using ultrasonic propagation control above 200 MHz.

The Ultrasonic System Research Institute has made it possible to control the nonlinear propagation of ultrasound by analyzing and applying measurement, analysis, and control techniques related to the propagation state of ultrasound as the acoustic characteristics of the target object. As a result, we have developed a technology that efficiently alleviates residual stress on the surface of components and homogenizes the entire surface. This technology for alleviating surface residual stress improves the fatigue strength against metal fatigue and achieves uniformity in various surface treatments. In particular, by considering the guided waves (surface elastic waves) of the target object in the setting and control of the ultrasound propagation state, we have developed control methods, tools, and systems that realize effective dynamic changes in the target object as a stimulus within a certain range that includes nonlinear phenomena. We have confirmed a wide range of effects on various surfaces of metal parts, plastic parts, and powder materials. This is a new surface treatment technology using ultrasound, which, including the general effects based on acoustic characteristics, can be utilized and developed as a distinctive inherent operational technology for the development of new materials, stirring, dispersion, cleaning, and chemical reaction experiments.
