- Optimization Technology for Cavitation and Acoustic Flow -

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.

Ultrasonic cleaning system that achieves ultrasonic control tailored to the purpose.

This is an effective device using a dedicated ultrasonic tank (original manufacturing method). Due to the high efficiency of ultrasonic utilization, standard tanks lack sufficient strength and durability. Depending on the target and purpose, multiple ultrasonic waves and a degassing fine bubble generation liquid circulation device are controlled based on sound pressure measurement analysis for cleaning, stirring, and surface modification. We propose various combinations and usage (control) methods. The key point is to achieve an ultrasonic propagation state tailored to the target, focusing on the "dissolved oxygen concentration distribution" and "liquid circulation" within the dedicated tank. << Degassing Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form.

Application of sweep oscillation control technology to control nonlinear phenomena of ultrasound.

The Ultrasonic System Research Institute has developed ultrasonic system technology that enables control of ultrasonic propagation states above 1-700 MHz by utilizing a megahertz ultrasonic oscillation control probe for ultrasonic equipment. This is a new application technology based on the measurement, analysis, evaluation, and techniques of ultrasonic propagation states, applicable to precision cleaning, processing, stirring, welding, plating, and more. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled for several tons of target objects even in a 1000-liter water tank with ultrasonic output below 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic wave phenomena and an abstract algebraic ultrasonic model. The key point is the use of tools (elastic bodies: metal, glass, resin). By confirming the ultrasonic propagation characteristics depending on the conditions of the target object, it is important to address it as an original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This phenomenon occurs due to the generation of harmonics resulting from original oscillation control, realized at high amplitudes through resonance phenomena, leading to ultrasonic vibration resonance phenomena.

Development of "Control Technology for Nonlinear Phenomena" Using a Small Pump

The Ultrasonic System Research Institute has developed "ultrasonic control technology" that dynamically controls nonlinear phenomena related to ultrasonic propagation by utilizing a small pump for liquid circulation. Nonlinear phenomena are evaluated through analysis using an ultrasonic tester. The complex changes in ultrasound (such as ultrasonic cleaners, ultrasonic probes, etc.) are confirmed through time-series data analysis of sound pressure from ultrasonic oscillation and reception, identifying various interactions. Based on the confirmation of these interactions, the oscillation control conditions using ultrasonic probes are optimized, achieving a dynamic ultrasonic control system tailored to specific objectives. In practical applications, such as ultrasonic cleaning, the ON/OFF control (or control of flow rate and velocity, etc.) of the current liquid circulation device is optimized by considering the ultrasonic propagation characteristics related to the installation state of the device and the surface elastic waves of the target object, including the output, oscillation frequency, and control conditions of the ultrasound. In particular, by utilizing the vibration characteristics of the pump to alternately circulate liquid and gas, new nonlinear effects of ultrasound and microbubbles are realized.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.
