Ultrasonic Nonlinear Oscillation Control Technology Using a Portable Ultrasonic Cleaner (50kHz 50W)

Combination technology of function generator and ultrasonic probe

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 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, 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 ultrasonic model. The key point is to confirm the ultrasonic propagation characteristics of the target object, and it is important to set the oscillation conditions of the function generator as a control method for the original nonlinear resonance phenomenon (Note 1). Note 1: Original Nonlinear Resonance Phenomenon This refers to the resonance phenomenon of ultrasonic vibrations that occurs when the generation of harmonics caused by original oscillation control is realized at a high amplitude due to resonance phenomena.

Control technology for acoustic flow (nonlinear phenomena) based on sound pressure measurement analysis.

The Ultrasonic System Research Institute has developed a system that applies technology to measure and analyze the state of ultrasonic waves propagating in the liquid within an ultrasonic tank, setting and controlling the propagation state of ultrasonic waves according to the effects of the tank's structure, strength, manufacturing conditions, and the state of liquid circulation. The liquid circulation within the ultrasonic tank is captured as a system, and the primary purpose of many ultrasonic (tank) applications is to predict or control the sound pressure changes of the liquid inside the tank. However, numerous issues have been pointed out in many implementations due to discrepancies between theory and practice. In response to such cases: 1) The removal of obstacles involves the use of statistical data analysis methods, which is the technology for measuring and analyzing ultrasonic propagation states. 2) Based on the results of data analysis related to the subject, the characteristics of the subject are confirmed, which is the technology for detecting the acoustic properties related to the surface elastic waves of the object. 3) Progressing to control realization through characteristic confirmation involves technology for controlling nonlinear phenomena. By employing the above methods, the utilization state of ultrasonic waves has been improved for efficient use, and there are numerous examples of original systems that have realized the intended use of ultrasonic waves.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when leaving the parking lot in my car..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Departure Warning Sensor] that detects vehicle departures using various sensors and alerts the surroundings with LED lights and buzzers. The device consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *Please note that a separate control panel including the controller and switching power supply (24V) is required when using the departure warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.
