A new surface inspection technology using megahertz ultrasonic oscillation—ultrasonic probes utilizing components with iron plating on polyimide film.

Control system using ultrasonic oscillation probe and receiving probe.

The Ultrasonic System Research Institute has developed a megahertz ultrasonic oscillation control system that applies acoustic characteristic analysis and evaluation technology related to the manufacturing of original products: ultrasonic oscillation probes. This is a new application system for cleaning, modification, inspection, and more, utilizing ultrasonic waves. It is also 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 utilization method of surface elastic waves. By confirming the propagation characteristics of ultrasonic waves 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 ultrasonic waves - Nonlinear characteristics - Response characteristics - Fluctuation characteristics - Effects due to interactions Note 2: Original nonlinear resonance phenomenon This occurs when the generation of harmonics caused by original oscillation control is realized at high amplitudes through resonance phenomena, resulting in ultrasonic vibration resonance phenomena.

Control technology for nonlinear ultrasonic sweep oscillation based on the classification of ultrasonic propagation phenomena.

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibrations propagation. Based on this classification, we have developed a nonlinear sweep oscillation control technology for ultrasound using a nonlinear resonant ultrasonic oscillation probe. This ultrasonic sweep oscillation control technology method controls the linear and nonlinear resonance effects according to the main frequency (power spectrum) of the dynamic characteristics (changes in nonlinear phenomena) related to the propagation state of the ultrasound. From previous experiments and data measurement analyses, we have been able to classify effective utilization methods into the following four recommended controls: 1: Two types of sweep oscillation control (linear type) 2: Three types of sweep oscillation control (nonlinear type) 3: Four types of sweep oscillation control (mixed type) 4: Dynamic control (variable type) based on the combinations above Furthermore, the variable type can be classified into the following three control types based on the sweep oscillation conditions: 1: Linear variable control type 2: Nonlinear variable control type 3: Mixed variable control type (dynamic variable type)

Relaxation and uniform treatment of surface residual stress using ultra-fine bubbles and megahertz acoustic flow control.

<<Deaeration Fine Bubble Generation Liquid Circulation Device>> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gas to form. The above describes the state of the deaeration liquid circulation device. 3) When the concentration of dissolved gas decreases, the size of the bubbles formed by cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles of less than 20μ are generated. The above describes the state of the deaeration microbubble generation liquid circulation device. 5) When ultrasonic waves are applied to the above-mentioned deaeration fine bubble generation liquid circulation device, the ultrasonic waves disperse and crush the fine bubbles, and when measuring the fine bubbles, the distribution of ultrafine bubbles becomes greater than that of fine bubbles. The above state indicates that ultrasonic waves can be stably controlled. 6) In the state where ultrasonic waves can be stably controlled, the original product: a megahertz ultrasonic oscillation control probe is used to control the oscillation of megahertz ultrasonic waves. The method of controlling the sound pressure level is achieved by controlling the original nonlinear resonance phenomenon of liquid circulation and megahertz ultrasonic waves, setting and controlling it to an effective dynamic state.
