Title: Kenzo Yoshihara: Innovator in Coin Validation Technology
Introduction
Kenzo Yoshihara is a notable inventor based in Konosu, Japan. He has made significant contributions to the field of coin validation technology, holding three patents that showcase his innovative approach to discerning the thickness and patterns of coins.
Latest Patents
Yoshihara's latest patents include a coin validator that utilizes a static capacitance system for non-contact detection of coin characteristics. This system features a pair of electrode assemblies, which include first and second sensor electrodes along with first and second guard ring electrodes. These guard ring electrodes prevent the dispersion of electric lines of force generated by the sensor electrodes. As a coin passes through the designated path, the inter-electrode capacitance changes, allowing for the detection of the coin's thickness and pattern. Another patent describes a coin validator that senses the passage of a coin, causing a change in the resonant frequency of a resonator. This fluctuation in resonant output voltage enables the detection of the coin's characteristics, with a variable capacitance diode providing feedback control to maintain the resonant frequency within a specified range.
Career Highlights
Throughout his career, Kenzo Yoshihara has worked with prominent companies in the industry, including Nippon Conlux and Nippon Coinco Co., Ltd. His work has significantly advanced the technology used in coin validation systems, making them more efficient and reliable.
Collaborations
Yoshihara has collaborated with notable individuals in his field, including Kenjiro Kachi and Hideaki Onda. These collaborations have contributed to the development of innovative solutions in coin validation technology.
Conclusion
Kenzo Yoshihara's contributions to coin validation technology through his patents and collaborations highlight his role as an influential inventor in this specialized field. His innovative approaches continue to shape the future of coin detection systems.
