Ultrasonic Cleaning (Control of Nonlinear Phenomena) Technology 1. Introduction This section introduces technologies that utilize the effects of acoustic flow related to ultrasound. Regarding ultrasonic cleaning, "The most important (effective) factor is acoustic flow." 2. What is Acoustic Flow? A flow occurs near the surface of the cleaning object placed in the ultrasonic cleaner. This flow is called acoustic flow. ...

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 has developed the following technologies: * Measurement, analysis, and evaluation techniques related to the nonlinearity of ultrasound, * Technology for controlling the dynamic characteristics of ultrasound through oscillation control, * Optimization techniques for cavitation and acoustic flow through the design, manufacturing, installation, and surface treatment methods of ultrasonic transducers and tanks, * Technology for adjusting various interactions using liquid circulation and microbubbles, * Technology for controlling the propagation state of surface acoustic waves with megahertz ultrasound. These technologies have been applied and developed into a "surface modification" technology using megahertz ultrasound. Surface treatment know-how: Standard settings Output: 13-15V Square wave: Duty 47.1% Sweep range: 500kHz to 13MHz for 2 seconds Settings for low-intensity targets (or long processing times) Output: 1-3V Square wave: Duty 47.1% Sweep range: 300kHz to 3MHz for 1 second (or 100kHz to 5MHz for 1 second) This is a setting for experiments; please do not use it for continuous operation for 8 hours (A propagation state of ultrasound above 700MHz can be achieved).

The Ultrasonic System Research Institute has developed a new surface inspection technology using megahertz ultrasonic oscillation based on its achievements in analyzing ultrasonic data propagating on the surface of target objects. Using this technology, we will evaluate the ultrasonic propagation characteristics of the items to be cleaned and compile a report proposing effective control, frequency, and output levels for ultrasonic cleaning machines. This method applies measurement and analysis techniques for "sound pressure and vibration" through oscillation control of ultrasonic probes. By using an original ultrasonic probe tailored to the vibration modes propagating on the surface of the target object, we can confirm the propagation state of ultrasonic waves in narrow grooves and edge areas. Furthermore, through original oscillation control, we will measure and analyze the dynamic characteristics of low-frequency propagation properties and the generation state of harmonics due to nonlinearity. This is an application of new ultrasonic oscillation control technology. By utilizing nonlinear phenomena related to megahertz ultrasonic propagation states that match the acoustic characteristics of the target object, it is possible to detect the unique acoustic properties of the object.
