Ultrasonic control technology using spectral sequences in abstract mathematics.

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).

To evaluate the complex and varying usage conditions of ultrasound, we do not rely solely on sound pressure and frequency; instead, we consider "timbre." We analyze it using a time series data autoregressive model and report and propose <evaluation and application> based on statistical models.

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.

Acoustic flow control technology using ultra-fine bubbles and megahertz ultrasound.

<<Deaeration Fine Bubble Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the bubble size of the dissolved gas due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles, and when measuring the fine bubbles, the distribution of ultrafine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In the state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz (1-20 MHz) ultrasonic waves. The method of controlling the sound pressure level is achieved by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasonic waves, setting and controlling it to an effective dynamic state.

Ultrasonic control technology based on the classification of nonlinear phenomena in which ultrasonic vibrations propagate.

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibration propagation by analyzing measurement data of ultrasonic propagation states using bispectral analysis. The method developed in this instance estimates the linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequencies (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to classify effective utilization methods into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type There are numerous successful cases of device development and control settings based on each of the above types. This technology will be offered as a consulting service. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation) 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) Note: The following tools will be used for analysis. Note: "R" is a free statistical processing language and environment.
