Improvement process for ultrasonic propagation efficiency due to harmonics above 200 MHz.

The Ultrasonic System Research Institute has made it possible to control the nonlinear propagation state of ultrasound by measuring, analyzing, and controlling the propagation state of ultrasound and applying it as the acoustic characteristics of the target object. As a result, we have developed a technology that efficiently alleviates the residual stress on the surface of components and homogenizes the entire surface. With this technology to alleviate surface residual stress, we have improved fatigue strength against metal fatigue and achieved uniformity in various surface treatments. In particular, by considering the guided waves (surface elastic waves) of the target object in the setting and control of the ultrasonic propagation state, we have developed control methods, tools, and systems that realize effective dynamic changes in the target object as a certain range of stimuli that include nonlinear phenomena. We have confirmed a wide range of effects on various surfaces of metal parts, plastic parts, and powder materials. This technology is offered as a consulting service.

Surface inspection using ultrasonic oscillation from ultrasonic probes (oscillating type, measuring type, resonant type, nonlinear type).

The Ultrasonic System Research Institute has developed a new component inspection technology using megahertz ultrasonic oscillation, based on its track record of analyzing ultrasonic data propagating on the surface of target objects. This method applies the measurement and analysis technology of "sound pressure and vibration" through the control of original ultrasonic probe oscillation. We provide consulting and explanations of ultrasonic evaluation technology by developing ultrasonic probes tailored to the purpose (vibration modes propagating on the surface of target objects). This is an application of new ultrasonic oscillation control technology. By utilizing nonlinear phenomena related to megahertz ultrasonic propagation states that match the acoustic characteristics of the target object, it is possible to detect new features regarding the surface condition of the target object. In particular, this fundamental technology serves as a new evaluation parameter for ultrasonic vibration, utilized in surface inspection of substrate components and preliminary evaluation of precision cleaning parts, based on the response characteristics derived from combinations of oscillation and reception. By measuring, analyzing, and evaluating the dynamic characteristics of ultrasonic waves related to surface elastic wave propagation phenomena, we have enabled effective utilization tailored to the purpose (evaluation) by constructing and modifying logical models.

Application of technology to analyze and evaluate the dynamic characteristics of ultrasound.

The Ultrasonic System Research Institute has developed a method (system) for the analysis and evaluation of ultrasound, applying "measurement, analysis, and control" technology related to the nonlinearity of ultrasound. We are providing on-site support for the additional installation of a degassing fine bubble generation liquid circulation system utilizing this technology. To utilize (control) the complex and changing conditions of ultrasound in a stable manner, we offer on-site services to add and confirm sound pressure measurements for the degassing fine bubble generation liquid circulation system in specific tanks present at the site. **Explanation of Degassing Fine Bubble Generation Liquid Circulation Technology** By ensuring appropriate liquid circulation and the diffusibility of fine bubbles, a uniform state of cleaning liquid is achieved. Ultrasound propagates through the uniform liquid, generating a stable state of ultrasound. From this state, liquid circulation control is performed to realize the desired ultrasonic effects (propagation state). This involves achieving a uniform sound pressure distribution throughout the tank, optimizing ultrasound, liquid circulation pumps, fine bubbles, etc. The operational control becomes the know-how for individual tanks.

Ultrasonic oscillation (sweep oscillation) system for controlling nonlinear phenomena

The Ultrasonic System Research Institute has developed a technology to control the nonlinear vibration phenomena of surface elastic waves based on the acoustic characteristics of original ultrasonic probes. The key point is the setting of sweep oscillation conditions using two ultrasonic probes (essentially, it cannot be controlled with just one probe for ultrasonic oscillation control. By combining the oscillation settings of the two probes, the occurrence of resonance phenomena and nonlinear phenomena can be controlled). Resonance phenomena and nonlinear phenomena can be controlled within a frequency range tailored to the intended use. In particular, when strong stimulation is required, this is achieved by utilizing low-frequency resonance phenomena (e.g., breaking glass). When high-frequency stimulation is needed, this is achieved by utilizing high-frequency nonlinear phenomena (e.g., 700 MHz stimulation).

The Ultrasonic System Research Institute has developed a technology to control the nonlinear phenomena of surface elastic waves (ultrasonic vibrations) that propagate through the target object, using an original ultrasonic system (sound pressure measurement analysis, oscillation control). **Technology for Controlling Nonlinear Ultrasonic Vibration Phenomena** 1) Control setting technology that adjusts the oscillation output, waveform, and variations of the oscillation control using a function generator, tailored to the acoustic characteristics of the target object. 2) Manufacturing technology for an ultrasonic oscillation control probe that enables control of changes in ultrasonic oscillation voltage, including adjustments to the oscillation surface. 3) Manufacturing technology for an ultrasonic measurement probe that allows for the measurement of changes in ultrasonic vibrations at 100 megahertz, including adjustments to the oscillation surface. 4) Optimization technology for sweep oscillation conditions. Using the above technologies, we control (optimize) the propagation state of ultrasonic waves according to specific objectives. Note: The dynamic control of ultrasonic waves is performed based on the analysis and evaluation of sound pressure data related to nonlinear phenomena, considering the interaction between the acoustic characteristics of the target object and ultrasonic oscillation control. (Sound pressure measurement, analysis, confirmation, and evaluation are conducted using an ultrasonic tester.)

Application technologies of measurement, analysis, and control using ultrasonic testers - sweep oscillation technology and pulse oscillation technology.

The Ultrasonic System Research Institute has developed a completely new dynamic control technology for ultrasound by utilizing two function generators. Through oscillation with two different waveforms (sweep), we have realized a technology to control the nonlinear phenomena of ultrasound. Note: Nonlinear (resonance) phenomena By generating (10th order and higher) harmonics through original oscillation control and resonating with low-frequency vibration phenomena, we have achieved the generation of high-amplitude harmonics, which is the nonlinear (resonance) phenomenon of ultrasonic vibrations. By optimizing the ultrasonic propagation characteristics of various materials according to their intended use, efficient ultrasonic oscillation control becomes possible. Through the measurement and analysis of sound pressure data from ultrasonic testers, this is a system technology that controls the dynamic changes of surface elastic waves according to the intended purpose.

Ultrasonic cleaning system that achieves ultrasonic control tailored to the purpose.

This is an effective device using a dedicated ultrasonic tank (original manufacturing method). Due to the high efficiency of ultrasonic utilization, standard tanks lack sufficient strength and durability. Depending on the target and purpose, multiple ultrasonic waves and a degassing fine bubble generation liquid circulation device are controlled based on sound pressure measurement analysis for cleaning, stirring, and surface modification. We propose various combinations and usage (control) methods. The key point is to achieve an ultrasonic propagation state tailored to the target, focusing on the "dissolved oxygen concentration distribution" and "liquid circulation" within the dedicated tank. << Degassing Fine Bubble (Microbubble) Generation Liquid Circulation Device >> 1) By narrowing the suction side of the pump, cavitation is generated. 2) Cavitation causes bubbles of dissolved gases to form. The above describes the state of the degassing liquid circulation device. 3) As the concentration of dissolved gases decreases, the bubble size of dissolved gases due to cavitation becomes smaller. 4) Through appropriate liquid circulation, fine bubbles (microbubbles) smaller than 20μ are generated. The above describes the state of the degassing microbubble generation liquid circulation device.

The recognition that "the PDF invoice received from the other party must be stored as electronic data" is widely accepted. However, is that response truly sufficient for perfection? ◆ The "receipt" of electronic transactions includes issuance and delivery The Electronic Bookkeeping Act defines "electronic transactions" as the receipt of electromagnetic records related to transaction information. Breaking down the term "receipt" is key to understanding. - "Receipt": Receiving electronic data such as invoices and receipts from business partners - "Issuance": Issuing and delivering electronic data such as invoices and estimates to business partners When downloading a PDF from your company's accounting system and attaching it to an email, or concluding electronic contracts through a cloud-based invoicing service, both the receiving party and the issuing party (your company) are obligated to store the data. 【Utilizing paperlogic DESKTOP for document management】 - Elimination of manual input - Assurance of reliable searchability - Centralized management of receipt and issuance → paperlogic DESKTOP addresses the challenges of complex metadata management in the storage of these issued documents.
