Title: Ryoichi Ishihara and His Patent for a Persistent Current Switch.
Introduction
Ryoichi Ishihara is an inventor associated with Technische Universiteit Delft in Rijswijk, the Netherlands. His listed patent concerns controlling persistent current in a superconducting loop.
Latest Patents
Ishihara is credited with 1 patent, titled “Persistent Current Switch.” The invention describes a switch that uses a piece of superconducting material within a superconducting loop. An illumination system directs light onto the material to influence its electrical resistance, while being configured so the light does not substantially heat it. This approach is intended to help control or initiate persistent current in the loop.
Career Highlights
The available information associates Ishihara with Technische Universiteit Delft. His patent focuses on superconductivity and the control of electrical resistance through illumination.
Collaborations
Salahuddin Nur and Jaime Oscar Tenorio Pearl are listed as Ishihara’s coworkers.
Conclusion
Ryoichi Ishihara’s listed invention explores a light-based method for controlling persistent current in a superconducting loop, reflecting research connected with Technische Universiteit Delft.
