Ultrasonic sound pressure data analysis and evaluation technology (Leading to new ultrasonic applications from ultrasonic sound pressure and vibration data)

Improvement process for ultrasonic propagation efficiency due to harmonics above 200 MHz.

The Ultrasonic System Research Institute has made it possible to control the nonlinear propagation state of ultrasound by measuring, analyzing, and controlling the propagation state of ultrasound and applying it as the acoustic characteristics of the target object. As a result, we have developed a technology that efficiently alleviates the residual stress on the surface of components and homogenizes the entire surface. With this technology to alleviate surface residual stress, we have improved fatigue strength against metal fatigue and achieved uniformity in various surface treatments. In particular, by considering the guided waves (surface elastic waves) of the target object in the setting and control of the ultrasonic propagation state, we have developed control methods, tools, and systems that realize effective dynamic changes in the target object as a certain range of stimuli that include nonlinear phenomena. We have confirmed a wide range of effects on various surfaces of metal parts, plastic parts, and powder materials. This technology is offered as a consulting service.

The Ultrasonic System Research Institute (located in Hachioji, Tokyo) has developed a completely new vibration measurement technology using its original product (ultrasonic tester). The ultrasonic sound pressure measurement analysis technology developed so far applies "measurement, analysis, and control" techniques related to the nonlinear phenomena of ultrasound. From the accumulation of data measuring, analyzing, and evaluating the dynamic characteristics of ultrasound propagating on surfaces, we have developed a technology that can measure, analyze, and evaluate vibration states from low frequencies (0.1 Hz) to high frequencies (200 MHz). This technology enables new countermeasures based on new vibration phenomena concerning vibrations and noise from buildings and roads, equipment, devices, walls, pipes, desks, handrails, and the moment of metal melting during welding, as well as instantaneous vibrations during machining. This is a new method and technology, and various application cases have developed from the analysis results obtained so far. In particular, continuous data collection for a standard measurement time of 72 hours is possible, allowing measurement of very low-frequency vibrations and irregularly fluctuating vibrations.

[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.
