A technology for controlling two types of ultrasonic probes from a single oscillation channel.

The Ultrasonic System Research Institute has developed a technology to control nonlinear ultrasonic phenomena by utilizing the interactions generated by simultaneously oscillating two types of ultrasonic probes from one oscillation channel of a function generator. Note: Nonlinear (resonance) phenomena refer to the resonance phenomenon of ultrasonic vibrations that occurs when harmonics generated by original oscillation control are realized at high amplitudes due to resonance. By optimizing the ultrasonic propagation characteristics of various materials according to their intended purpose, efficient ultrasonic oscillation control becomes possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this system technology allows for the dynamic changes of surface elastic waves to be controlled according to their intended use. Practically, the use of multiple (two types of) ultrasonic probes for multiple (two types of) oscillations (sweep oscillation, pulse oscillation) generates complex vibration phenomena (original nonlinear resonance phenomena), achieving high sound pressure at high frequency propagation states, or low frequency propagation states with high sound pressure levels tailored to the desired natural frequency.

Development of ultrasonic sound pressure data analysis and evaluation technology considering interaction and response characteristics.

We are evaluating the characteristics of ultrasonic equipment according to the purpose of use. <<Analysis and Evaluation of Ultrasonic Sound Pressure Data>> 1) Regarding time series data, we analyze and evaluate the statistical properties of the measurement data (stability and changes of ultrasound) through feedback analysis using a multivariate autoregressive model. 2) The effects of the oscillation part due to ultrasonic oscillation are analyzed and evaluated in relation to the surface condition of the target object through impulse response characteristics and autocorrelation analysis as response characteristics of the ultrasonic vibration phenomenon. 3) We evaluate the interaction between the oscillation and the target object (cleaning items, cleaning solutions, water tanks, etc.) through the analysis of power contribution rates. 4) Regarding the use of ultrasound (cleaning, processing, stirring, etc.), we analyze and evaluate the dynamic characteristics of ultrasound based on the nonlinear phenomena (results of bispectral analysis) of the target object (propagation of surface elastic waves) or the ultrasound propagating in the target liquid, which are the main factors of the ultrasonic effect. This analysis method is realized based on past experiences and achievements by adapting the dynamic characteristics of complex ultrasonic vibrations to the analysis methods of time series data using ultrasonic measurement data.

Cavitation and acoustic flow of ultrasonic phenomena

- Experimental and Research Cycle of Abstract Algebra Models and Ultrasonic Phenomena - Basic Information The Ultrasonic System Research Institute has developed ultrasonic <dynamic control> technology that optimizes the interaction of ultrasonic vibrations based on various analysis results of ultrasonic propagation states using an original ultrasonic system (sound pressure measurement analysis and oscillation control). 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 concerning the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately in practical applications and is proposed and addressed as consulting (with increasing achievements in precision cleaning and stirring at the nano level). 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 characteristics) 4) Detection of interactions (analysis of power contribution rates)

To achieve results in sales outsourcing, the structure of communication and reproducibility are key.

Technology for Adding Megahertz Ultrasound to Ultrasonic Cleaners — Nonlinear Oscillation Control Technology Using Original Ultrasonic Probes —

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology that enables the use of ultrasonic propagation states above 200 MHz with oscillation below 20 MHz by utilizing a function generator and an original ultrasonic oscillation probe in relation 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, ultrasonic stimulation to the target object can be controlled with an ultrasonic output of less than 20W, even in a 5000-liter water tank. 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. Ultrasonic probe for vibration measurement: Outline specifications - Measurement range: 0.01 Hz to 100 MHz - Oscillation range: 1 kHz to 25 MHz - Propagation range: 1 kHz to over 900 MHz - Materials: Stainless steel, LCP resin, silicon, Teflon, glass, etc. - Measurement equipment: Example - Oscilloscope - Oscillation equipment: Example - Function generator

On the main factors (interactions) of ultrasonic utilization.

The Ultrasonic System Research Institute has confirmed that the main factor in the utilization of ultrasound is interaction, based on its achievements and experience in sound pressure measurement analysis related to ultrasonic cleaning and stirring, as well as the development and manufacturing of ultrasonic oscillation control probes tailored to specific purposes in ultrasonic processing and surface treatment. Until now, it was believed that nonlinear phenomena were the main cause; however, due to the nonlinear phenomena of ultrasound, the propagation characteristics of the target objects—such as structure, material, surface condition, and propagation path—dynamically change, making it often difficult to evaluate simply. Therefore, upon examining the causes of this dynamic change, it was confirmed that the factors of dynamic change are the interaction between the propagating ultrasound and the target object. As the cleaning and processing levels reach the nanoscale and above, the generation of harmonics due to nonlinear phenomena also increases from several megahertz to several hundred megahertz. However, the above conditions are very unstable and difficult to reproduce. As a countermeasure, by implementing oscillation control that considers the interactions related to ultrasonic propagation, dynamic ultrasonic control (changes in sound pressure level and propagation frequency range) tailored to the intended use has been realized.

Surface Residual Stress Relaxation Treatment Using Megahertz Ultrasonic Waves - Control Technology for Surface Elastic Waves through Nonlinear Oscillation Control

The Ultrasonic System Research Institute has developed a technology that applies the control of ultrasound and fine bubbles within a water tank to stimulate the surfaces of various materials and components with megahertz acoustic flow. In particular, the homogenization of surface residual stress has led to many achievements. << Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Bubbles of dissolved gas are produced due to cavitation. The above describes the state of the deaeration liquid circulation device. ... 6) In a stable and controllable state of ultrasound, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz (1-20 MHz) ultrasound. The optimization method for cavitation and acoustic flow achieves effective dynamic control of ultrasound by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasound. By organizing previous consulting responses, sound pressure measurements, and analyses, we have confirmed various know-how (specific methods related to individual objects and devices) and developed usage methods.

Refinement of the column base reinforcement method "Smart Fit Method"! / Welding-free work is now possible when the existing structure is an H-beam.

Senkushia Co., Ltd. (Headquarters: Minato-ku, Tokyo, Representative Executive Officer: Nobuyasu Kasahara), which manufactures and sells construction materials and related works, has refined the "Smart Fit Method" for reinforcing the base of steel columns. In seismic reinforcement work for steel structures, it is common to attach reinforcement members to the building using welding. However, welding methods require considerable time and effort for work and fire protection, and they also carry the risk of fire during construction. Therefore, there is a demand for safe, reliable, and simple joining methods that do not use fire. In the previous Smart Fit Method, welding was necessary when installing reinforcement columns, but with this refinement, it has become possible to perform work without welding when the existing column is an H-beam. Additionally, the improvement of the toughness index (F value) of the column base has been achieved.

Control technology for chemical reactions through the control of nonlinear phenomena in ultrasound — Optimization technology for cavitation and acoustic flow —

The Ultrasonic System Research Institute has developed a technology to utilize (control) "nonlinear phenomena related to the generation of harmonics in ultrasound" by analyzing ultrasonic sound pressure measurement data (bispectral analysis, etc.) according to specific objectives. With this technology, when using multiple ultrasonic transducers with different frequencies, it becomes possible to set (manage) the propagation state of ultrasound influenced by harmonics. Therefore, it is possible to achieve appropriate or effective combinations of frequencies. This is very effective as it allows for the detection and confirmation of effective propagation states for cleaning, surface modification, and the promotion of chemical reactions. Furthermore, by combining the control of standing waves with the control of liquid circulation, dynamic control becomes possible to change the effects of cavitation and acceleration (acoustic flow) according to specific objectives. Through original measurement and analysis technology for ultrasonic propagation states, we have confirmed numerous effective cases related to the surface conditions of various components, including cleaning, stirring, surface modification, and chemical reactions.

Ultrasonic sound pressure data analysis and evaluation technology (Leading to new ultrasonic applications from ultrasonic sound pressure and vibration data)

The Ultrasonic System Research Institute conducts consulting related to ultrasonic applications using a technology that measures, analyzes, and evaluates the propagation state of ultrasound, applying feedback analysis techniques based on multivariate autoregressive models. By organizing the measurements, analyses, and results obtained from ultrasonic testers chronologically, we establish and verify new evaluation criteria (parameters) that indicate the appropriate ultrasonic state for the intended purpose. Note: - Nonlinear characteristics (dynamic characteristics of acoustic flow) - Response characteristics - Fluctuation characteristics - Effects due to interactions By developing original measurement and analysis methods that consider the acoustic properties of the target object and surface elastic waves, we deepen our understanding of the relationships between various effects related to vibration phenomena, referencing statistical mathematical concepts. As a result, there is an increasing number of cases demonstrating that new nonlinear parameters are very effective regarding the propagation state of ultrasound and the surface of the target object. In particular, evaluation cases related to cleaning, processing, and surface treatment effects lead to successful control and improvement based on favorable confirmations.
