Ultrasonic probe oscillation method (consulting support for control know-how)

The Ultrasonic System Research Institute offers custom-made ultrasonic probes that can control ultrasonic propagation states above 900 MHz. We manufacture and develop original ultrasonic oscillation control probes tailored to your needs. The key point is the operational verification 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. Currently, we are capable of addressing the following ranges: Ultrasonic Probe: Outline Specifications - Measurement Range: 0.01 Hz to 100 MHz - Oscillation Range: 0.5 kHz to 25 MHz - Propagation Range: 0.5 kHz to over 900 MHz (analytical confirmation) Materials: Stainless steel, LCP resin, silicone, Teflon, glass, etc. Oscillation Equipment: Example - Function Generator By understanding the acoustic properties of metals, resins, glass, etc., we achieve propagation states tailored to your objectives regarding sound pressure levels, frequencies, and dynamic characteristics through oscillation control. This is a fundamental technology based on measurement, analysis, and evaluation techniques for ultrasonic propagation states.

The Ultrasonic System Research Institute has developed a technology to adjust the ultrasonic propagation characteristics of ultrasonic elements (piezoelectric elements) based on measurement, analysis, and evaluation results regarding the propagation state of ultrasound, utilizing ultrasonic systems (sound pressure measurement, oscillation control). To utilize the surface acoustic waves of ultrasonic elements (piezoelectric elements) according to specific purposes, special surface treatments are applied to the element's surface. It allows for adjustments to the sound pressure level and frequency range of the propagating ultrasound. By achieving dynamic ultrasonic propagation control through the combination of ultrasound (oscillation control) and surface acoustic waves, it has evolved into an adjustment technology based on the characteristics derived from the analysis of sound pressure data. The key point is the optimization of oscillation conditions (waveform, output, frequency, variations, etc.) to enable efficient control of nonlinear phenomena caused by surface acoustic waves. As specific technologies mentioned above, we provide consulting services for system technologies that control nonlinear phenomena (bi-spectra) resulting from the interaction of ultrasound with tanks and tools, tailored to specific purposes (cleaning, stirring, processing, welding, surface treatment, stress relief treatment, inspection, etc.).

The Ultrasonic System Research Institute has developed manufacturing technology for ultrasonic probes that can control ultrasonic propagation states from 500 Hz to 900 MHz, utilizing the iron plating technology of Japan Barrel Industry Co., Ltd. We have created a new ultrasonic propagation tool. This ultrasonic technology is available for consulting. Ultrasonic Probe: Overview Specifications - Measurement Range: 0.01 Hz to 200 MHz - Oscillation Range: 1.0 kHz to 25 MHz - Propagation Range: 0.5 kHz to over 900 MHz (confirmed by analysis) - Materials: Stainless steel, LCP resin, silicone, Teflon, glass, etc. - Oscillation Equipment: Example - Function Generator Regarding usage, the key point is the setting of various parameters utilizing the characteristics of a discrete-value function generator through digital control. By using a nonlinear resonant ultrasonic oscillation probe, the control range of sound pressure levels due to resonance phenomena is greatly expanded, significantly differing from conventional resonance phenomena. This allows for the optimization of control settings based on sound pressure measurement analysis, avoiding phenomena such as damage or destruction.
