(Development of a control system based on measurement and analysis of ultrasonic cleaning machines) The Ultrasonic System Research Institute has developed a technology that applies techniques for measuring and analyzing the state of ultrasonic cleaning machines propagating in liquid, to set and control the state of ultrasonic cleaning machines according to the effects of tank structure, strength, manufacturing conditions, and liquid circulation state. This technology analyzes and evaluates the dynamic characteristics of complex ultrasonic vibrations (Note 1) in relation to various factors, allowing for the setting of cavitation and acceleration effects according to specific purposes through the configuration of circulation pump settings (Note 2). Note 1: This utilizes the original technology of the Ultrasonic System Research Institute, which employs "ultrasonic oscillation control" technology considering "timbre." Note 2: The know-how involves settings related to the relationships at the boundaries of the cleaning machine, cleaning liquid, and air. It can also be applied to cleaning tanks that do not have an overflow structure. Regarding the self-organization of micro-flows, control of acoustic flow has become possible through degassing, aeration, ultrasound, and elastic waves on the tank surface.

Ultrasonic oscillation and control technology based on measurement and analysis using an ultrasonic tester.

The Ultrasonic System Research Institute has developed a technology to control nonlinear ultrasonic phenomena by utilizing the interactions generated from simultaneously oscillating two types of ultrasonic probes from one oscillation channel of a function generator. Note: Nonlinear (resonance) phenomena refer to the resonance phenomenon that occurs when the generation of harmonics produced by original oscillation control is realized at high amplitudes, resulting in ultrasonic vibration resonance. 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 dynamic changes of surface elastic waves to be controlled according to their intended use. In practical terms, multiple (two types of) ultrasonic probes generate multiple (two types of) oscillations (sweep oscillation, pulse oscillation), which create complex vibration phenomena (original nonlinear resonance phenomena), achieving high sound pressure at high frequency propagation states, or achieving low frequency propagation states with high sound pressure levels tailored to the desired natural frequency.
