Improvement technology for ultrasonic cleaners based on sound pressure measurement analysis of nonlinear phenomena.

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 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 Reality of Cleaning> 1: Managing cleaning equipment and cleaning solutions is difficult. In the case of cleaning devices that utilize vibrational phenomena as a physical action, the low-frequency vibrational phenomena caused by the installation of the device, along with the device's inherent vibrational phenomena, and the vibrational phenomena of the objects being cleaned and tools interact with each other, resulting in a complex change in the vibrational state. In many cases where cleaning effects are observed, nonlinear vibrational phenomena occur. To confirm nonlinearity and manage it, logical learning and an understanding of vibration measurement are necessary. As for the chemical action of cleaning solutions, in devices that utilize cleaning effects, managing the concentration of detergents is important, but measuring the concentration distribution within the tank is a challenging situation. Various distributions change due to interactions with the environment, such as liquid temperature, humidity, air temperature, and atmospheric pressure. In particular, the distribution of dissolved gas concentration has a significant impact on chemical reactions, but no methods are known to achieve uniform dissolved gas concentration. (Using the diffusivity of fine bubbles is one method.) If detergents are added but only increase the variability of the concentration distribution, it will result in greater variability in cleaning results. ....

The Ultrasonic System Research Institute has developed a classification method for the phenomenon of ultrasonic vibrations propagation 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 frequency (power spectrum) related to the ultrasonic propagation state. From previous data analysis, we have been able to categorize effective utilization methods 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 made it possible to efficiently set and adjust various conditions for the intended purpose and effect.
