Technology that utilizes (optimizes) multiple different frequency "ultrasonic transducers."

The Ultrasonic System Research Institute has released a technology that applies measurement, analysis, and control techniques related to the propagation state of ultrasound to alleviate the surface residual stress of ultrasonic transducers using an ultrasonic and microbubble generation liquid circulation system. This technology for alleviating surface residual stress enables improvements in fatigue strength against metal fatigue. In particular, by considering the guided waves (surface elastic waves) of the target object in the propagation state of ultrasound, we have developed a method to realize effective ultrasonic irradiation conditions through settings, tooling, and control. We have confirmed a wide range of effects on various types of metal parts, resin parts, and powder materials.

Application of technology to analyze and evaluate the dynamic characteristics of ultrasound The Ultrasound System Research Institute has developed a method (system) for the analysis and evaluation of ultrasound, utilizing measurement, analysis, and control technology related to the nonlinearity of ultrasound. Using this technology, we are providing on-site support for the additional installation of a degassing fine bubble generation liquid circulation system. To utilize (control) the complex and changing conditions of ultrasound in a stable manner according to the purpose, we offer on-site services to add, install, and confirm sound pressure measurements for the degassing fine bubble generation liquid circulation system in specific tanks present at the site. <Example> *Month* *Day* - Consultation and confirmation via email *Month* *Day* 13:00 - 13:30 - Greetings and meeting 13:30 - 16:30 - Confirmation (simple sound pressure measurement) Setting up the degassing fine bubble generation liquid circulation system Operation explanation Confirmation (sound pressure measurement) 16:30 - 17:00 - Discussion based on sound pressure data 17:00 - 18:00 - Reserve A simple analysis of the measurement data will be conducted.

The Ultrasonic System Research Institute utilizes a <degasification and microbubble generation liquid circulation system> to achieve effective ultrasonic control tailored to specific purposes. Explanation of Ultrasonic Liquid Circulation Technology 1) We use a dedicated ultrasonic tank (original manufacturing method). 2) The installation of the tank involves: 1: Using specialized materials. 2: Optimizing the natural vibration, ultrasonic frequency, and output. 3) The ultrasonic transducer is installed using specialized materials. (These materials can limit the utilization states of standing waves, cavitation, and acoustic flow.) 4) We use a degasification and microbubble generation device. (The standard dissolved oxygen concentration is 5-6 mg/l.) 5) The tank and ultrasonic transducer undergo surface modification. With the above settings and the diffusibility of microbubbles, a uniform cleaning liquid state is achieved. Ultrasonic waves propagate through the uniform liquid, generating a stable ultrasonic state. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). The operation control of the ultrasonic device, degasification device, liquid circulation pump, etc., is our expertise.
