Ultrasonic plating treatment technology (Nihon Barrel Industry Co., Ltd.)

The Ultrasonic System Research Institute has published measurement and analysis data on ultrasonic sound pressure using its original product: an ultrasonic tester. << Measurement and Analysis of Ultrasonic Sound Pressure >> 1) By using feedback analysis through a multivariate autoregressive model, we will examine and evaluate the stability and changes of ultrasonic waves (many ultrasonic cleaning devices have issues in this regard). 2) Through the analysis of impulse response characteristics and autocorrelation, we will conduct examinations and evaluations related to tanks, transducers, and tooling (these are the most important parameters in ultrasonic processing). 3) By analyzing power contribution rates, we will examine and evaluate the optimization of ultrasonic (frequency and output), tanks, and liquid circulation (this examination is crucial for mass production devices). 4) Through nonlinear (bispectral) analysis of other factors (propagation of surface elastic waves), we will conduct examinations and evaluations tailored to the target object for cleaning, stirring, dispersion, and modification (this is necessary for research and development of ultrasonic utilization methods, including applications in nanotechnology). This analysis method is realized by adapting the measurement data to the dynamic characteristics of complex ultrasonic vibrations.

Technology for stably utilizing fine bubbles with a spherical size of 20μm or less—nano-level cleaning method that controls acoustic flow of ultrasound— 1-1. Basics of Ultrasound 1-2. Propagation Phenomena of Ultrasonic Vibration 1-3. Fine Bubbles (Microbubbles) *Properties of Microbubbles* 1) Bubbles of about 10μm rise slowly over approximately 3 hours to a height of 1m. 2) The generated bubbles exist independently without coalescing, resulting in excellent dispersion. 3) They have the property of slowly rising in water and adsorbing tiny debris to bring it to the surface. ... 13) The negative potential depends on the pH of the water. 14) Microbubbles have excellent scattering characteristics for ultrasound. 15) Microbubbles collapse as a resonance phenomenon when exposed to ultrasonic irradiation. These properties are expected to be further elucidated in the future, but currently contain many unknown aspects.
