Ultrasonic sound pressure measurement analysis device and oscillation control device.

The Ultrasonic System Research Institute has released a technology that applies measurement, analysis, and control techniques related to the propagation state of ultrasound to alleviate the surface residual stress of ultrasonic transducers using an ultrasonic and microbubble generation liquid circulation system. This technology for alleviating surface residual stress enables improvements in 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 realize effective ultrasonic irradiation conditions through settings, tooling, and control. We have confirmed a wide range of effects on various types of metal parts, resin parts, and powder materials.

－－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, in collaboration with Nippon Barrel Industry Co., Ltd., is implementing a "plating method" utilizing ultrasound and fine bubbles for plating treatment. Utilization status of ultrasonic oscillation control probes: - Measurement analysis range: 1 Hz to 200 MHz - Oscillation range: 0.1 kHz to 25 MHz - Ultrasonic propagation range into the plating treatment tank: 5 kHz to over 200 MHz (analysis confirmed) - Oscillation equipment example: Function generator Oscillation method: - Control settings are made corresponding to the acoustic characteristics of the target object. - As a result, by controlling the original nonlinear resonance phenomenon, we achieve ultrasonic propagation states tailored to the purpose. Based on the measurement, analysis, and evaluation of ultrasonic propagation states, this is a new ultrasonic control technology for precision cleaning, processing, stirring, and inspection. By utilizing the acoustic characteristics (surface elastic waves) of various materials, ultrasonic stimulation can be controlled for several tons of structures and machine tools in a 3000-liter water tank with an ultrasonic output of less than 20 W. This was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic wave motion and an abstract algebraic ultrasonic model.

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. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in self-correlation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response) 4) Detection of interactions (analysis of power contribution rates)
