Research and development equipment for "nanotechnology" using ultrasound.

<The Reality of Cleaning> 1: Managing cleaning equipment and cleaning solutions is difficult. In the case of cleaning devices that utilize vibrational phenomena as a physical action, the low-frequency vibrational phenomena caused by the installation of the device, along with the device's inherent vibrational phenomena, and the vibrational phenomena of the objects being cleaned and tools interact with each other, resulting in a complex change in the vibrational state. In many cases where cleaning effects are observed, nonlinear vibrational phenomena occur. To confirm nonlinearity and manage it, logical learning and an understanding of vibration measurement are necessary. As for the chemical action of cleaning solutions, in devices that utilize cleaning effects, managing the concentration of detergents is important, but measuring the concentration distribution within the tank is a challenging situation. Various distributions change due to interactions with the environment, such as liquid temperature, humidity, air temperature, and atmospheric pressure. In particular, the distribution of dissolved gas concentration has a significant impact on chemical reactions, but no methods are known to achieve uniform dissolved gas concentration. (Using the diffusivity of fine bubbles is one method.) If detergents are added but only increase the variability of the concentration distribution, it will result in greater variability in cleaning results. ....

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.
