Acoustic property test using ultrasound (confirmation of suitability for ultrasonic cleaning)

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.

－－Abstract Algebra Model and Ultrasonic Experimentation and Examination Cycle－－ (Optimization Techniques for Resonance Phenomena and Nonlinear Phenomena) The Ultrasonic System Research Institute has developed ultrasonic <dynamic control> technology that optimizes the interaction of ultrasonic vibrations based on various analytical results of ultrasonic propagation states obtained through an original ultrasonic system (sound pressure measurement analysis and oscillation control) using an abstract algebra model. Note: Control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. Compared to previous control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we are proposing and responding to it as a consulting service (there is an increasing track record in precision cleaning, stirring, and processing at the nano level). Note: Parameters: Power spectrum, autocorrelation, bispectrum, power contribution ratio, impulse response characteristics, and others.

The Ultrasonic System Research Institute has developed ultrasonic system technology that enables the control of ultrasonic propagation states above 1-900 MHz by installing a megahertz ultrasonic oscillation control probe in resin containers. By measuring, analyzing, evaluating, and technically assessing the ultrasonic propagation characteristics of containers and mounting components, effective ultrasonic irradiation for precision cleaning, processing, stirring, welding, and plating can be achieved. This represents a new application technology for ultrasound. Utilizing various acoustic properties (surface elastic waves) based on the structure, shape, and manufacturing methods of various materials, ultrasonic stimulation can be controlled for objects weighing several tons even in a 1000-liter water tank with an ultrasonic output of less than 20W. This was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic model of ultrasound. Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in self-correlation) 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 control the nonlinear vibration phenomena of surface elastic waves through oscillation control techniques based on the acoustic characteristics of the probes, and we provide consulting services for various ultrasonic utilization technologies. The key point is the optimization of the ultrasonic propagation section (Note). Note: By relaxing and homogenizing surface residual stress, stable ultrasonic oscillation control becomes possible. Setting technology for oscillation control conditions: 1) Setting of oscillation waveforms corresponding to the vibration modes of devices and equipment. 2) Setting of sweep conditions corresponding to the vibration modes of devices and equipment. 3) Setting of output levels corresponding to the vibration modes of devices and equipment. To achieve this, it is important to evaluate the characteristics related to ultrasonic propagation conditions through operational verification of the ultrasonic propagation characteristics of the original probe (sound pressure level, frequency range, nonlinearity, dynamic characteristics, etc.). Ultrasonic propagation characteristics: 1) Detection of vibration modes (changes in autocorrelation). 2) Detection of nonlinear phenomena (changes in bispectrum). 3) Detection of response characteristics (impulse response). 4) Detection of interactions (power contribution rate).
