Technology for adjusting the ultrasonic propagation characteristics of ultrasonic elements (piezoelectric elements).

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 classification method for the phenomenon of ultrasonic vibrations propagation through the measurement and analysis of ultrasonic propagation states. This classification method estimates linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequency (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to categorize effective utilization methods into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type Furthermore, the variable type can be further classified into the following three types: 1: Linear variable type 2: Nonlinear variable type 3: Mixed variable type (dynamic variable type) There are numerous successful cases regarding the application of ultrasonic technology based on the development of devices, control settings, and inspections based on the above types. In particular, regarding stability and changes, detailed classification by frequency components has made it possible to efficiently set and adjust various conditions for the intended purpose and effect.

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.
