- Surface modification technology (stress relaxation and uniformity) through nonlinear oscillation control of original ultrasonic probes -

The Ultrasonic System Research Institute has made it possible to control the nonlinear propagation state of ultrasound by utilizing measurement, analysis, and control technologies related to the propagation state of ultrasound as the acoustic characteristics of the target object. As a result, we have developed and advanced technology to efficiently alleviate residual stress on the surface of components. This technology for alleviating surface residual stress improves fatigue strength against metal fatigue and achieves 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 and tools that realize effective dynamic changes in the target object as stimuli that include nonlinear phenomena. We have confirmed a wide range of effects on various types of metal parts, resin parts, and powder materials. This is a new surface treatment technology using ultrasound, which, including the general effects based on acoustic characteristics, can be utilized and developed as a distinctive inherent operational technology for the development of new materials, stirring, dispersion, cleaning, and chemical reaction experiments.

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.

To stabilize the effects of cavitation, a statistical perspective is essential.

The Ultrasonic System Research Institute is developing technologies related to effective "measurement, analysis, and evaluation methods" utilizing a <statistical approach> in the field of ultrasonic applications. <About the statistical approach> Statistical mathematics has both abstract and concrete aspects, and through contact with concrete entities, abstract thoughts or methods are developed. This is the characteristic of statistical mathematics. Regarding ultrasonic research, "a statistical perspective is essential for stabilizing the effects of cavitation." <About models> Models are constructed with the aim of effectively advancing understanding, prediction, control, etc., regarding the subject. Constructing an accurate model is difficult, and discussions are always conducted using a suitably "rounded" representation of the complexity of the subject. In that sense, the process of constructing or building a model requires statistical thinking. Propagation characteristics of ultrasound: 1) Detection of vibration modes (changes in autocorrelation) 2) Detection of nonlinear phenomena (changes in bispectrum) 3) Detection of response characteristics (analysis of impulse response characteristics) 4) Detection of interactions (analysis of power contribution rates)

Technology to control low-frequency resonance phenomena and high-frequency nonlinear phenomena.

The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface acoustic waves using ultrasonic oscillation control technology. By confirming the basic acoustic characteristics of ultrasonic waves (response characteristics, propagation characteristics) for various targets (water tanks, transducers, probes, fixtures, objects, etc.), we realize ultrasonic propagation states tailored to specific applications through oscillation control. By setting the oscillation conditions for sweep oscillation and pulse oscillation using two or more types of nonlinear resonant ultrasonic oscillation control probes, we dynamically control high sound pressure level resonance phenomena and the generation of harmonics (nonlinear phenomena of the 10th order and above), achieving high-frequency propagation states of over 100 MHz. Note: Precision cleaning examples Sweep oscillation: 70 kHz to 15 MHz, 15 W Pulse oscillation: 13 MHz, 8 W This technology is an efficient method for utilizing low-power ultrasonic oscillation.

Ultrasound consulting specialized in measurement and analysis of ultrasonic propagation conditions.

The Ultrasonic System Research Institute conducts consulting related to ultrasonic applications using a technology that measures, analyzes, and evaluates the propagation state of ultrasound, applying feedback analysis techniques based on multivariate autoregressive models. By organizing the measurements, analyses, and results obtained using ultrasonic testers in chronological order, we establish and confirm new evaluation criteria (parameters) that indicate the appropriate ultrasonic state for specific purposes. Note: - Nonlinear characteristics (dynamic characteristics of acoustic flow) - Response characteristics - Fluctuation characteristics - Effects due to interactions By developing original measurement and analysis methods that consider the acoustic properties of the target object and surface elastic waves, we deepen our understanding of the relationships between various effects related to vibration phenomena, drawing on the principles of statistical mathematics. As a result, there is an increasing number of cases demonstrating that new nonlinear parameters are highly effective regarding the propagation state of ultrasound and the surface of the target object. In particular, evaluation cases related to cleaning, processing, and surface treatment effects lead to successful control and improvement based on good confirmations.

A truck berth is a space in a logistics warehouse where trucks can be parked to load and unload goods. By installing sensors in the truck berth to display the occupancy status, it is possible to quickly guide trucks to available spaces. Additionally, sharing the occupancy status with warehouse workers allows for a swift start to loading and unloading, improving overall productivity and reducing truck waiting times. 【Target Products】 - Occupancy detection sensor HM-UX2/UW2 (ceiling-mounted, ultrasonic type) ■ Benefits of Implementation Benefit 1: The HM-UX2 can be installed at high positions without height restrictions.
