Consulting services for the manufacturing and evaluation technology of ultrasonic probes.

The Ultrasonic System Research Institute offers custom-made ultrasonic probes that can control ultrasonic propagation states above 900 MHz. We manufacture and develop original ultrasonic oscillation control probes tailored to your needs. The key point is the operational verification of the original probes. The responsiveness to dynamic changes in ultrasonic transmission and reception is the most important factor. This characteristic determines the range of applications for harmonics. Currently, we are capable of addressing the following ranges: Ultrasonic Probe: Outline Specifications - Measurement Range: 0.01 Hz to 100 MHz - Oscillation Range: 0.5 kHz to 25 MHz - Propagation Range: 0.5 kHz to over 900 MHz (analytical confirmation) Materials: Stainless steel, LCP resin, silicone, Teflon, glass, etc. Oscillation Equipment: Example - Function Generator By understanding the acoustic properties of metals, resins, glass, etc., we achieve propagation states tailored to your objectives regarding sound pressure levels, frequencies, and dynamic characteristics through oscillation control. This is a fundamental technology based on measurement, analysis, and evaluation techniques for ultrasonic propagation states.

The Ultrasonic System Research Institute has developed a technology that applies the control of ultrasound and fine bubbles within a water tank to stimulate the surfaces of various materials and components with megahertz acoustic flow. In particular, the homogenization of surface residual stress has led to many achievements. << Deaeration Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Bubbles of dissolved gas are produced due to cavitation. The above describes the state of the deaeration liquid circulation device. ... 6) In a stable and controllable state of ultrasound, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz (1-20 MHz) ultrasound. The optimization method for cavitation and acoustic flow achieves effective dynamic control of ultrasound by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasound. By organizing previous consulting responses, sound pressure measurements, and analyses, we have confirmed various know-how (specific methods related to individual objects and devices) and developed usage methods.

The Ultrasonic System Research Institute has developed a completely new technology for controlling vibrations using original products (ultrasonic systems). Based on the analysis and evaluation of ultrasonic sound pressure measurement and oscillation control technology developed so far, we perform oscillation control of megahertz ultrasonic waves based on the analysis and evaluation of nonlinear phenomena in ultrasonics. From the accumulation of data measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves propagating on surfaces, we apply technology that can <measure, analyze, and evaluate> vibration states from low frequencies (0.1 Hz) to high frequencies (over 900 MHz). Regarding vibrations and noise from buildings and roads, equipment, devices, walls, piping, desks, handrails... the vibrations at the moment of metal melting during welding, instantaneous vibrations during machining, and the complex vibration states of entire manufacturing devices and systems... new countermeasures based on vibration measurement and analysis have become possible. This is a new method and technology, and various application cases have developed from the results obtained so far. In particular, since continuous data collection for a standard measurement time of 72 hours is possible, we can measure and respond to very low frequency vibrations and irregularly fluctuating vibrations.

The Ultrasonic System Research Institute has developed a dynamic liquid circulation control technology for ultrasound based on statistical analysis and control of dynamic systems, utilizing original sound pressure measurement analysis technology (ultrasonic tester) (Hiroji Akaike / co-author Toichiro Nakagawa / co-author: Science Publishing). The liquid circulation in the ultrasonic tank is treated as a system for analysis and control. The purpose of many ultrasonic (tank) applications is to predict or control the sound pressure changes of the liquid within the tank. However, in many practical examples, numerous issues have been pointed out due to discrepancies between theory and practice. In response to such cases: 1) The removal of obstacles is achieved through the use of statistical data analysis methods (measurement and analysis technology of ultrasonic propagation conditions). 2) The characteristics of the target are confirmed (technology for detecting acoustic characteristics). 3) Progress is made towards achieving control (cavitation control technology). There are numerous practical examples using these methods. Reference: Statistical Analysis and Control of Dynamic Systems: Hiroji Akaike / co-author Toichiro Nakagawa / co-author: Science Publishing.
