System Overview (Recommended System): :: Ultrasonic Tester NA 100 MHz type :: Oscillation System 20 MHz type System Overview (Ultrasonic Tester NA 100 MHz type): This is a measurement system using an ultrasonic probe. The ultrasonic probe is attached to the target object for oscillation and measurement. The measured data is analyzed considering position, state, and elastic waves, detecting various acoustic performances. System Overview (Ultrasonic Oscillation System (20 MHz type)): This is a system that utilizes a commercially available function generator.

The Ultrasonic System Research Institute specializes in: - Ultrasonic oscillation control technology (Original product: Ultrasonic oscillation control probe) - Measurement technology for ultrasonic propagation conditions (Original product: Ultrasonic tester) - Analysis technology for ultrasonic propagation conditions (Nonlinear analysis system for time-series data) - Optimization technology for ultrasonic propagation conditions (Optimization processing of sound and ultrasound) - Development and manufacturing technology for ultrasonic oscillation probes and propagation tools - Technology for controlling surface acoustic waves in systems ... By applying the above technologies, we are developing and applying control technology for ultrasound (nonlinear resonance phenomena) utilizing the combination of sound and ultrasound. Note: Original nonlinear resonance phenomenon The generation of harmonics caused by original oscillation control is realized at high amplitudes through resonance phenomena, resulting in ultrasonic vibrations (resonance phenomena of harmonics above the 10th order). As an application example of the combination technology of sound and ultrasound, we are achieving effective utilization of ultrasound (cleaning, surface modification, stirring, promoting chemical reactions, etc.) tailored to the conditions of various parts and materials (in air, underwater, in contact with elastic bodies, etc.) and controlling vibrations in various systems.

The Ultrasonic System Research Institute has developed a megahertz ultrasonic oscillation control technology that applies acoustic characteristic analysis and evaluation techniques related to the manufacturing of original products: ultrasonic oscillation probes. This is a new application technology for cleaning, modification, inspection, and more, utilizing ultrasound. It is possible to apply control through the combination of low-frequency vibrations and sounds. Developed from an engineering (experimental and technical) perspective on elastic waves and an abstract algebraic ultrasonic model, it serves as an applied system technology. The key point is the method of utilizing surface acoustic waves. By confirming the propagation characteristics of ultrasound depending on the conditions of the target object (Note 1), it is important to address this as an original nonlinear resonance phenomenon (Note 2). Note 1: Propagation characteristics of ultrasound - Nonlinear characteristics - Response characteristics - Fluctuation characteristics - Effects due to interactions Note 2: Original nonlinear resonance phenomenon - The generation of harmonics caused by original oscillation control, realized at high amplitudes through resonance phenomena, leads to the resonance phenomenon of ultrasonic vibrations. We believe this technology can be utilized in various fields.

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibrations propagating through the measurement and analysis of ultrasonic propagation states. This classification method estimates linear and nonlinear resonance effects based on the dynamic characteristics (changes in nonlinear phenomena) of the main frequencies (power spectrum) related to the ultrasonic propagation state. From previous data analysis, effective utilization methods have been classified into the following four types: 1: Linear type 2: Nonlinear type 3: Mixed type 4: Variable type Furthermore, the variable type can be further classified into the following three types: 1: Linear variable type 2: Nonlinear variable type 3: Mixed variable type (dynamic variable type) There are numerous successful cases regarding the application of ultrasonic technology based on the development of devices, control settings, and inspections based on the above types. In particular, regarding stability and changes, detailed classification by frequency components has enabled efficient setting and adjustment of various conditions for the intended purpose and effect.
