Sweep oscillation control system below 1 MHz

The Ultrasonic System Research Institute has developed ultrasonic oscillation control technology that utilizes the nonlinear vibration phenomena of surface acoustic waves through a combination of sweep oscillation and pulse oscillation. Using two types of ultrasonic oscillation control probes, we set the conditions for sweep oscillation and pulse oscillation based on the intended purpose and the measurement and analysis of interactions. By utilizing the low-frequency resonance phenomena matched to the natural frequencies of the target objects, water tanks, and tools, it becomes possible to propagate high sound pressure within a 3000-5000 liter water tank even with an output of around 30W. As a dynamic change, we can simultaneously achieve the generation of harmonics at the 10th, 30th, 100th order, etc., in response to a 1MHz oscillation. The key point is to evaluate the dynamic vibration characteristics of the system based on the measurement and analysis of sound pressure data. We have established and confirmed a new evaluation criterion (parameter) that indicates the state of ultrasonic waves suitable for the purpose. (Note): - Nonlinear characteristics (dynamic characteristics of acoustic flow) - Response characteristics - Fluctuation characteristics - Effects due to interactions

The Ultrasonic System Research Institute has published a method for applying the "Ultrasonic Oscillation System (1 MHz)" that allows for easy control of ultrasonic oscillation through timer control. Specific examples: 1) Preventing degradation of machining oil by irradiating it with ultrasound at night. 2) Improving quality through ultrasonic irradiation on NC machines. 3) Ultrasonic irradiation on shelves storing metal and resin parts (surface modification). 4) Improving fluidity and uniformity of concentration by irradiating plating solutions, cleaning solutions, solvents, etc. with ultrasound. ... 19) Others: 1: Combined use with various vibrations (e.g., motors, etc.). 2: Maintenance through ultrasonic irradiation during holidays (2-3 hours). 3: Aging treatment through ultrasonic irradiation. ... ... Combined use with fine bubbles. Control of combined oscillation of multiple ultrasounds. Use of ultrasonic propagation tools. It is important to set parameters based on sound pressure measurement analysis of the vibration state of various equipment. Based on that, we will perform ultrasonic oscillation control settings to effectively utilize resonance phenomena and nonlinear phenomena. If you are interested, please contact us via email.

The Ultrasonic System Research Institute has developed application technologies for ultrasonic systems using a quantum mechanics model based on "the mathematics of the shape and sound of drums" and "fundamental experiments and analyses on ultrasonic propagation phenomena." As a fundamental application of this technology, we have realized rational design techniques and standards for ultrasonic systems tailored to the purposes of ultrasonic utilization. The technology developed this time was achieved through an abstract algebra model that adapts the oscillation and propagation states of ultrasound to the quantum mechanical wave function. Unlike previous development methods, we determine the control conditions of the system by interpreting the energy levels (corresponding to the order of harmonics) of the ultrasonic propagation state of the target object as perturbations (results from bispectral analysis) of nonlinear phenomena and sound (low-frequency vibrations). Furthermore, through the "evaluation technology for ultrasonic devices" at the Ultrasonic System Research Institute, we have confirmed specific effects of this method. As application examples, there has been an increase in proposals for "ultrasonic welding," "ultrasonic processing," and "ultrasonic plating," among others.

The Ultrasonic System Research Institute has developed ultrasonic cleaning technology that enables acoustic flow control from 1 to 100 MHz by utilizing ultrasonic humidifiers in relation to ultrasonic cleaners. This is a new application technology for precision cleaning, processing, and stirring based on the measurement, analysis, evaluation, and technology of ultrasonic propagation states. By utilizing the acoustic properties (surface elastic waves) of various materials, ultrasonic stimulation can be controlled even in a 1000-liter water tank with an ultrasonic output of less than 20W. It was developed as an application method for nonlinear phenomena through an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model. The key point is the use of tools (elastic bodies: metal, glass, resin). By confirming the propagation characteristics of ultrasonic waves based on the conditions of the target object, it is important to address this as an original nonlinear resonance phenomenon. Note 1: Original Nonlinear Resonance Phenomenon This occurs when the generation of harmonics produced by original oscillation control is realized at high amplitudes through resonance phenomena, resulting in ultrasonic vibration resonance. We are implementing proposals in various consulting services.
