Megahertz ultrasonic cleaner (consulting available)

The Ultrasonic System Research Institute has developed a new component inspection technology using megahertz ultrasonic oscillation based on its track record of analyzing ultrasonic data propagating on the surface of objects. This method applies the measurement and analysis technology of "sound pressure and vibration" through the control of original ultrasonic probe oscillation. We provide consulting and explanations of ultrasonic evaluation technology through the development of ultrasonic probes tailored to the purpose (vibration modes propagating on the surface of objects). 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 new features regarding the surface condition of the object. In particular, this fundamental technology serves as a new evaluation parameter for ultrasonic vibrations, utilized in surface inspection of substrate components and pre-evaluation of precision cleaning parts, leveraging the response characteristics derived from combinations of oscillation and reception. By measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves related to the propagation phenomena of surface elastic waves, we have enabled effective use tailored to the purpose (evaluation) through the construction and modification of logical models.

The Ultrasonic System Research Institute has developed a technology to control nonlinear ultrasonic phenomena by optimizing various interactions through the oscillation control of two types of ultrasonic probes from two oscillation channels of a function generator. Note: Nonlinear (resonance) phenomenon The resonance phenomenon that occurs due to the generation of harmonics resulting from original oscillation control, leading to high amplitude ultrasonic vibrations. By optimizing the ultrasonic propagation characteristics of various materials 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 allows for the control of dynamic changes in surface elastic waves according to their intended use.

The Ultrasonic System Research Institute has developed an application technology based on Shannon's juggling theorem, using classification methods related to ultrasonic propagation phenomena derived from bispectral analysis results of ultrasonic sound pressure measurement data. Specifically, we have developed an original product: a "method for controlling the oscillation of megahertz ultrasonic waves" using an ultrasonic oscillation control system. This technology is offered through consulting proposals and implementation support. To utilize ultrasonic propagation phenomena stably and efficiently, it is necessary to examine the response characteristics and interactions related to conditions other than ultrasonic oscillation devices and ultrasonic transducers, as well as to develop dedicated tools. By examining the oscillation waveforms and control conditions of ultrasonic waves, we can discover new ultrasonic effects (Note 1: original nonlinear resonance phenomena). By utilizing ultrasonic phenomena primarily driven by nonlinear effects according to specific purposes, efficient ultrasonic utilization can be achieved. In particular, there has been an increase in achievements in nano-level ultrasonic technologies (stirring, cleaning, etc.). Note 1: Original nonlinear resonance phenomenon This phenomenon occurs due to the generation of harmonics resulting from original oscillation control, which is realized at high amplitudes through resonance phenomena, leading to ultrasonic vibration resonance phenomena.

Basic Experiments on "Control Technology of Acoustic Flow" (Measurement, Analysis, and Control Techniques Using Ultrasonic Testers) The Ultrasonic System Research Institute has developed "Control Technology of Acoustic Flow" suitable for ultrasonic applications such as cleaning, processing, stirring, modification, and chemical reactions, effectively utilizing the acoustic characteristics and vibration modes of tools and flowing liquids according to specific purposes through ultrasonic testers. **Acoustic Flow** General Concept When a finite amplitude wave propagates through a gas or liquid, acoustic flow is generated. Acoustic flow occurs as a result of viscous losses from wave pulses, either in a free heterogeneous field or near obstacles in the sound field (such as cleaning objects, jigs, or liquid circulation) or near vibrating bodies, resulting in a unidirectional steady flow of matter due to inertial losses. Acoustic flow is an important enhancement factor in the majority of ultrasonic processing processes, purification, drying, emulsification, combustion, extraction, etc., significantly promoting heat exchange and material exchange within the medium. The effects of acoustic flow in processing operations are determined by their velocity and dimensional factors.
