Ultrasonic probe propagation characteristics test

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.

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.

The Ultrasonic System Research Institute has developed a technology for ultrasonic <dynamic control> that optimizes the interaction of ultrasonic vibrations based on various analysis results of ultrasonic propagation states using an original ultrasonic system and an abstract algebra model. Note: The control of resonance phenomena (low harmonics) and nonlinear phenomena (high harmonics) is achieved by setting oscillation control conditions based on a logical model. In contrast to existing control technologies, this technique establishes and implements optimal control states tailored to the purposes of ultrasonic applications (cleaning, stirring, processing, etc.) through new measurement and evaluation parameters (note) concerning the entire propagation path of ultrasonic vibrations, including various propagation tools. This is a method and technology that can be applied immediately, and we offer it as consulting services (there is an increasing track record of precision cleaning and stirring at the nano level). Note: Using original technology (ultrasonic tester), we measure, analyze, and evaluate dynamic changes in the propagation state of water tanks, transducers, target objects, and tools, among others.

Surface inspection using ultrasonic oscillation from ultrasonic probes (oscillating type, measuring type, resonant type, nonlinear type).

The Ultrasonic System Research Institute has developed a new component inspection technology using megahertz ultrasonic oscillation, based on its track record of analyzing ultrasonic data propagating on the surface of target objects. This method applies the measurement and analysis technology of "sound pressure and vibration" through the control of original ultrasonic probe oscillation. We provide consulting and explanations of ultrasonic evaluation technology by developing ultrasonic probes tailored to the purpose (vibration modes propagating on the surface of target objects). This is an application of new ultrasonic oscillation control technology. By utilizing nonlinear phenomena related to megahertz ultrasonic propagation states that match the acoustic characteristics of the target object, it is possible to detect new features regarding the surface condition of the target object. In particular, this fundamental technology serves as a new evaluation parameter for ultrasonic vibration, utilized in surface inspection of substrate components and preliminary evaluation of precision cleaning parts, based on the response characteristics derived from combinations of oscillation and reception. By measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves related to surface elastic wave propagation phenomena, we have enabled effective utilization tailored to the purpose (evaluation) by constructing and modifying logical models.

Application of technology to analyze and evaluate the dynamic characteristics of ultrasound.

The Ultrasonic System Research Institute has developed a method (system) for the analysis and evaluation of ultrasound, applying "measurement, analysis, and control" technology related to the nonlinearity of ultrasound. We are providing on-site support for the additional installation of a degassing fine bubble generation liquid circulation system utilizing this technology. To utilize (control) the complex and changing conditions of ultrasound in a stable manner, we offer on-site services to add and confirm sound pressure measurements for the degassing fine bubble generation liquid circulation system in specific tanks present at the site. **Explanation of Degassing Fine Bubble Generation Liquid Circulation Technology** By ensuring appropriate liquid circulation and the diffusibility of fine bubbles, a uniform state of cleaning liquid is achieved. Ultrasound propagates through the uniform liquid, generating a stable state of ultrasound. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). This involves achieving a uniform sound pressure distribution throughout the tank, optimizing ultrasound, liquid circulation pumps, fine bubbles, etc. The operational control becomes the know-how for individual tanks.

On Monday, September 22, the Japan Meteorological Agency announced its three-month forecast for October to December. Due to the continued influence of conditions similar to the La Niña phenomenon until around December, the westerly winds are expected to flow more to the north than usual from October to early November, making it likely that warm air will cover the entire country. From late November to December, the westerly winds are expected to meander southward near Japan, and there may be periods when the winter pressure pattern strengthens. In December, the region is likely to be affected by cold air, and temperatures in western and eastern Japan are expected to be around or lower than the average for the season. For more details, please visit our website.
