The Ultrasonic System Research Institute offers custom-made ultrasonic probes that can control ultrasonic propagation states from 500 Hz to 900 MHz. We manufacture and develop original ultrasonic oscillation control probes tailored to specific purposes. The key point is the operational confirmation of the original probes. The responsiveness to dynamic changes in ultrasonic transmission and reception is the most important factor. This characteristic determines the range of applications for harmonics.

Ultrasonic oscillation and control technology based on measurement and analysis using an ultrasonic tester.

The Ultrasonic System Research Institute has developed a technology to control nonlinear ultrasonic phenomena by utilizing the interactions generated from simultaneously oscillating two types of ultrasonic probes from one oscillation channel of a function generator. Note: Nonlinear (resonance) phenomena refer to the resonance phenomenon that occurs when the generation of harmonics produced by original oscillation control is realized at high amplitudes, resulting in ultrasonic vibration 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. In practical terms, multiple (two types of) ultrasonic probes generate multiple (two types of) oscillations (sweep oscillation, pulse oscillation), which create complex vibration phenomena (original nonlinear resonance phenomena), achieving high sound pressure at high frequency propagation states, or achieving low frequency propagation states with high sound pressure levels tailored to the desired natural frequency.

Dynamic control technology of ultrasound through sweeping oscillation of multiple ultrasonic probes.

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibrations propagation through the measurement and analysis of ultrasonic propagation states. Based on this classification, we have developed a nonlinear sweep oscillation control technology for ultrasound using a nonlinear resonant ultrasonic oscillation probe. This ultrasonic sweep oscillation control technology dynamically controls the linear and nonlinear resonance effects according to the main frequency (power spectrum) related to the propagation state of the ultrasound, based on the dynamic characteristics (changes in nonlinear phenomena). From previous experiments and data measurement analyses, we have been able to classify effective utilization methods into the following four recommended controls: 1. Two types of sweep oscillation control (linear type) 2. Three types of sweep oscillation control (nonlinear type) 3. Four types of sweep oscillation control (mixed type) 4. Dynamic control (variable type) based on the combinations above. Furthermore, the variable type can be classified into the following three control types based on the sweep oscillation conditions: 1. Linear variable control type 2. Nonlinear variable control type 3. Mixed variable control type (dynamic variable type)

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.
