Technology for adding megahertz ultrasound to ultrasonic cleaners.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing multiple function generators. This technology enables the control of nonlinear ultrasonic phenomena through oscillation with several different waveforms (sweeping). Note: Nonlinear (resonance) phenomena By generating harmonics of the 10th order or higher through original oscillation control and resonating with low-frequency vibration phenomena, the generation of high-amplitude harmonics has been achieved, resulting in nonlinear (resonance) phenomena of ultrasonic vibrations. By optimizing the ultrasonic propagation characteristics of various components 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 dynamically controls the changes in surface elastic waves according to the intended application. Ultrasonic Oscillation Control Probe Measurement and analysis range: 1 Hz to 200 MHz Oscillation range: 0.5 kHz to 25 MHz Ultrasonic propagation range: 5 kHz to over 900 MHz (analysis confirmed) Ultrasonic propagation characteristics: 1) Detection of vibration modes 2) Detection of nonlinear phenomena 3) Detection of response characteristics 4) Detection of interactions

The Ultrasonic System Research Institute conducts consulting related to the use of ultrasound by utilizing a technology that measures, analyzes, and evaluates the propagation state of ultrasound, applying feedback analysis techniques based on multivariate autoregressive models. By organizing the measurements, analyses, and results obtained using ultrasonic testers in a time series, we have developed a new evaluation standard (nonlinear phenomenon analysis parameters) that indicates the state of ultrasound suitable for the purpose. Note: - Nonlinear characteristics (harmonic generation characteristics) - Response characteristics - Fluctuation characteristics - Effects due to interactions 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)

The Ultrasonic System Research Institute is applying and developing manufacturing technology for original ultrasonic probes. We have developed technology to optimize the nonlinear vibration phenomenon of surface acoustic waves through oscillation control technology based on the acoustic characteristics of the probes, and we provide consulting services for various ultrasonic utilization technologies. Note 1: Original nonlinear resonance phenomenon The resonance phenomenon of ultrasonic vibrations occurs due to the generation of harmonics resulting from original oscillation control of ultrasonic waves, which achieves high amplitude through resonance. The key point is the optimization of the ultrasonic propagation section. Note 2: By relaxing and homogenizing surface residual stress, stable ultrasonic oscillation control becomes possible. Technology for setting oscillation control conditions: 1) Setting of oscillation waveforms corresponding to the ultrasonic propagation characteristics of the device/equipment. 2) Setting of sweep conditions corresponding to the ultrasonic propagation characteristics of the device/equipment. 3) Setting of output levels corresponding to the ultrasonic propagation characteristics of the device/equipment. 4) Adjustment of various interactions corresponding to the ultrasonic propagation characteristics of the device/equipment.

The Ultrasonic System Research Institute has developed a completely new technology for controlling vibrations using original products (ultrasonic systems). Based on the analysis and evaluation of ultrasonic sound pressure measurement and oscillation control technology developed so far, we perform oscillation control of megahertz ultrasonic waves based on the analysis and evaluation of nonlinear phenomena in ultrasonics. From the accumulation of data measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves propagating on surfaces, we apply technology that can <measure, analyze, and evaluate> vibration states from low frequencies (0.1 Hz) to high frequencies (over 900 MHz). Regarding vibrations and noise from buildings and roads, equipment, devices, walls, piping, desks, handrails... the vibrations at the moment of metal melting during welding, instantaneous vibrations during machining, and the complex vibration states of entire manufacturing devices and systems... new countermeasures based on vibration measurement and analysis have become possible. This is a new method and technology, and various application cases have developed from the results obtained so far. In particular, since continuous data collection for a standard measurement time of 72 hours is possible, we can measure and respond to very low frequency vibrations and irregularly fluctuating vibrations.
