Ultrasonic system using a degassed fine bubble generation liquid circulation device

Acoustic flow control technology using ultra-fine bubbles and megahertz ultrasound.

<<Deaeration Fine Bubble Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the bubble size of the dissolved gas due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles, and when measuring the fine bubbles, the distribution of ultrafine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In the state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz (1-20 MHz) ultrasonic waves. The method of controlling the sound pressure level is achieved by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasonic waves, setting and controlling it to an effective dynamic state.

Application of technology to control the interaction between ultrasound and water tanks.

The Ultrasonic System Research Institute has developed a technology for controlling "nonlinear phenomena of ultrasound (acoustic flow)" by combining a portable ultrasonic cleaner with megahertz oscillation control using ultrasonic probes. This technology controls the dynamic characteristics of ultrasound (cavitation and acoustic flow) based on the analysis of changing ultrasonic sound pressure data (nonlinear). Tailored to the structure, material, and acoustic properties of specific target objects, it measures and confirms the interactions between ultrasound, the target object, the water tank, fixtures, and cleaning solutions to set optimal oscillation conditions for the ultrasonic probe according to the intended purpose. Note: Oscillation waveform, oscillation output, control conditions, etc. (e.g., square wave, duty 47%, 13V, sweep oscillation, 3-18 MHz, etc.) In particular, the dynamic characteristics of harmonics generated by acoustic flow control enable responses at the nano level (emulsification, dispersion, cleaning, processing, etc.). By applying and developing examples of dispersing metal powders to nanosize, it has been put into practical use in material development, chemical reaction control systems, and more.

Optimization of Ultrasonic Propagation State Based on Acoustic Pressure Measurement Analysis - Optimal Control of Resonance Phenomena and Nonlinear Phenomena -

Methods to Improve the Current Ultrasonic Cleaning Machine (Development of Optimization Technology for Ultrasonic Tanks and Liquid Circulation) The Ultrasonic System Research Institute has developed technology to control the propagation state of ultrasonic waves by analyzing the effects of the structure, strength, and manufacturing conditions of the ultrasonic tank, as well as by setting the method of liquid circulation within the tank. This technology allows for the analysis and evaluation of the dynamic characteristics of complex ultrasonic vibrations in relation to various factors, enabling the setting of the circulation pump method to adjust the effects of cavitation and acceleration according to specific objectives. Note: The settings regarding the relationship between the tank, circulating liquid, and air are proprietary knowledge. This technology can also be applied to tanks that do not have an overflow structure. As a specific response, we can address the issues of ultrasonic attenuation caused by the current tank by adjusting the settings of the liquid circulation pump. In particular, for precise cleaning at the nano level, we propose additional measures for oscillation control using megahertz ultrasonic oscillation probes.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
