Effects of Megahertz Ultrasound (Improvement of Ultrasonic Cleaners)

Machining technology using ultrasonic systems (sound pressure measurement analysis, oscillation control).

The Ultrasonic System Research Institute has developed "ultrasonic oscillation control (processing) technology" that utilizes the acoustic characteristics (vibration response characteristics and nonlinear phenomena) of objects (tools, target items, etc.) through a sound pressure measurement analysis device (ultrasonic tester) and a megahertz ultrasonic oscillation control probe. With this developed technology, it has become possible to control nonlinear vibration phenomena in target objects through "ultrasonic oscillation and output control," achieving dynamic control of ultrasonic waves (changes in bispectrum). The original ultrasonic oscillation control probe allows for the utilization and control of nonlinear effects of ultrasonic vibrations. This is an effective ultrasonic utilization (control) technology tailored to applications such as processing, cleaning, surface modification, and promoting chemical reactions. There are interactions with the acoustic characteristics of cutting tools (drills, reamers, cutters, knives, etc.) and the size and material of cutting oils, jigs, and target objects, making the analysis (self-correlation, impulse response, contribution rate, bispectrum) complex. However, various optimizations based on the analysis results of sound pressure measurement data become possible.

Technology for Controlling Nonlinear Phenomena of Ultrasound

The Ultrasonic System Research Institute has developed a technology to control the nonlinear phenomena of surface elastic waves (ultrasonic vibrations) that propagate through the target object, using an original ultrasonic system (sound pressure measurement analysis, oscillation control). << Technology to Control Nonlinear Phenomena of Ultrasound >> 1) A control setting technology that adjusts the oscillation output, waveform, and variations of the oscillation control using a function generator to match the acoustic characteristics of the target object. 2) Manufacturing technology for ultrasonic oscillation control probes that enable control of changes in ultrasonic oscillation voltage, including adjustments to the oscillation surface. 3) Manufacturing technology for ultrasonic measurement probes that make it possible to measure changes in ultrasonic vibrations at 100 megahertz, including adjustments to the oscillation surface. 4) Optimization technology for sweep oscillation conditions. Using the above technologies, we control (optimize) the propagation state of ultrasound according to the intended purpose.

Ultrasonic oscillation control technology for controlling nonlinear vibration phenomena

This is a control technology based on measurement, analysis, and evaluation techniques of ultrasonic propagation states, featuring an original nonlinear resonance phenomenon (Note 1). It represents a new application technology for precision cleaning, processing, stirring, inspection, and surface treatment. Note 1: Original Nonlinear Resonance Phenomenon This phenomenon occurs due to the generation of harmonics through original oscillation control, which achieves high amplitude ultrasonic vibrations through resonance phenomena. To efficiently utilize the acoustic properties (surface elastic waves) of various materials, the relaxation treatment of residual stress distribution on surfaces can be easily realized. From an engineering (experimental and technical) perspective on elastic waves and the ultrasonic model of abstract algebra, the original oscillation control method (Note 2) has been developed as an application method for nonlinear phenomena. Note 2: Original Oscillation Control Method Two types of ultrasonic oscillation are performed: one is sweep oscillation control, and the other is pulse oscillation control. Detailed settings are based on the purpose, target object, and tooling, and are configured according to a logical model from the vibration system as a whole.

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.

Original product: Ultrasonic control technology based on measurement, analysis, and evaluation of acoustic flow using an ultrasonic tester.

The Ultrasonic System Research Institute has developed a "flow-type ultrasonic (acoustic flow) control technology" that dynamically controls the propagation state of ultrasound (acoustic flow) through liquid circulation using a small pump. By using an ultrasonic tester to analyze the complex changes in flow and ultrasound, including the interactions of the water tank, liquid (microbubbles), and ultrasonic transducer, this system technology allows for the control of acoustic flow changes tailored to specific applications. In practical terms, it is a method for optimizing various interactions and vibration modes while considering the installation state of the liquid circulation device and the surface elastic waves of the target object, enabling ON/OFF control (or control of flow rate, flow velocity, etc.) of the current liquid circulation device. In particular, by utilizing the characteristics of the pump to alternately circulate liquid and gas, new effects of ultrasound and microbubbles are being realized. In nano-level applications, as a "flow-type ultrasonic system," efficient ultrasonic utilization has been achieved through "ultrasonic showers" that include frequency changes of over 300 megahertz.

- Technology combining sweep oscillation with ultrasonic probes and ultrasonic cleaners -

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology that enables the utilization of ultrasonic propagation states above 100 MHz by applying a function generator and ultrasonic probe to ultrasonic cleaners. This is a new application technology based on the measurement, analysis, evaluation, and techniques of ultrasonic propagation states, aimed at precision cleaning, processing, and stirring. By utilizing the acoustic properties (surface elastic waves) of various materials, it is possible to control ultrasonic stimulation above 100 MHz to the target object with an ultrasonic output of less than 20 W, even in a 1000-liter water tank. This was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic model of ultrasound. The key point is to confirm the ultrasonic propagation characteristics of the target object, which is important for setting the oscillation conditions of the ultrasonic oscillation control probe as an optimization of the system's vibration modes related to sweep oscillation and pulse oscillation, serving as a control method for the original nonlinear resonance phenomenon.

Application of a new surface inspection technology using megahertz ultrasonic oscillation.

The Ultrasonic System Research Institute has developed a new surface inspection technology using megahertz ultrasonic oscillation based on its track record of analyzing ultrasonic data propagating on the surface of target objects. Using this technology, we will evaluate the ultrasonic propagation characteristics of the items to be cleaned and compile a report proposing effective control, frequency, and output levels for ultrasonic cleaning machines. This method applies measurement and analysis techniques for "sound pressure and vibration" by controlling the oscillation of the ultrasonic probe. By using an original ultrasonic probe tailored to the vibration modes propagating on the surface of the target object, we can confirm the propagation state of ultrasonic waves in narrow grooves and edge areas. Furthermore, through original oscillation control, we will measure and analyze the dynamic characteristics of low-frequency propagation properties and the generation state of harmonics due to nonlinearity.
