<<Analysis and Evaluation of Ultrasonic Sound Pressure Data>> 1) Regarding time series data, we will 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 will be analyzed and evaluated in terms of the response characteristics of ultrasonic vibration phenomena concerning the surface condition of the target object through impulse response characteristics and autocorrelation analysis. 3) The interaction between the oscillation and the target object (cleaning items, cleaning solution, water tank, etc.) will be evaluated through the analysis of power contribution rates. 4) Regarding the use of ultrasound (cleaning, processing, stirring, etc.), we will 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 analytical method is realized based on past experiences and achievements, adapting the analysis techniques of time series data to the measurement data of ultrasound to capture the dynamic characteristics of complex ultrasonic vibrations.

Ultrasonic oscillation (sweep oscillation) system for controlling nonlinear phenomena

The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface elastic waves based on the acoustic characteristics of original ultrasonic probes. The key point is the setting of sweep oscillation conditions using two ultrasonic probes (essentially, it cannot be controlled with just one probe for ultrasonic oscillation control. By combining the oscillation settings of the two probes, the occurrence of resonance phenomena and nonlinear phenomena can be controlled). Resonance phenomena and nonlinear phenomena can be controlled within a frequency range tailored to the intended use. In particular, when strong stimulation is required, this is achieved by utilizing low-frequency resonance phenomena (e.g., breaking glass). When high-frequency stimulation is needed, this is achieved by utilizing high-frequency nonlinear phenomena (e.g., 700 MHz stimulation).

- Surface modification technology (stress relaxation and uniformity) through nonlinear oscillation control of original ultrasonic probes -

The Ultrasonic System Research Institute has made it possible to control the nonlinear propagation state of ultrasound by utilizing measurement, analysis, and control technologies related to the propagation state of ultrasound as the acoustic characteristics of the target object. As a result, we have developed and advanced technology to efficiently alleviate residual stress on the surface of components. This technology for alleviating surface residual stress improves 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 ultrasonic propagation state, we have developed control methods and tools that realize effective dynamic changes in the target object as stimuli that include nonlinear phenomena. We have confirmed a wide range of effects on various types of metal parts, resin 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.

On Monday, September 22, the Japan Meteorological Agency announced its three-month forecast for October to December. Due to the continued influence of conditions similar to the La Niña phenomenon until around December, the westerly winds are expected to flow more to the north than usual from October to early November, making it likely that warm air will cover the entire country. From late November to December, the westerly winds are expected to meander southward near Japan, and there may be periods when the winter pressure pattern strengthens. In December, the region is likely to be affected by cold air, and temperatures in western and eastern Japan are expected to be around or lower than the average for the season. For more details, please visit our website.
