Title: The Innovative Contributions of Yoshiko Usui
Introduction
Yoshiko Usui is a prominent inventor based in Yokohama, Japan. She has made significant contributions to the field of fluid measurement technology, particularly through her innovative ultrasonic flow meters. With a total of 2 patents to her name, Usui's work exemplifies the intersection of engineering and practical application.
Latest Patents
Usui's latest patents include two distinct designs of ultrasonic flow meters. The first patent describes an ultrasonic flow meter designed to determine the flow rate of fluid through tubings. This device features a measuring tube with a constant diameter throughout its length and two ring-shaped oscillators positioned longitudinally along the tube. One of the oscillators generates an ultrasonic wave using electric AC energy, while the other detects the wave. The time taken for the wave to travel between the oscillators is measured, allowing for the calculation of the fluid's velocity.
The second patent also focuses on an ultrasonic flow meter, but it incorporates three ring-shaped oscillators. In this design, the central oscillator generates the ultrasonic wave, which is then detected by the forward and rearward oscillators. The flow rate of the fluid is determined by processing the detected waves through a comparator, showcasing Usui's innovative approach to enhancing measurement accuracy.
