Title: Denis Duquenoy: Innovator in Gyromagnetic Devices
Introduction
Denis Duquenoy is a notable inventor based in Livry Gargan, France. He has made significant contributions to the field of gyromagnetic devices, holding a total of 2 patents. His work focuses on miniaturized and integrated technologies that operate at ultra-high frequencies.
Latest Patents
Denis Duquenoy's latest patents include a method for assembling a miniaturized gyromagnetic device. This invention pertains to a gyromagnetic device such as an insulator, operating at ultra-high frequencies ranging from 1 to 40 GHz. The assembly of these devices requires high-precision positioning, typically achieved through bonding. In his isolator invention, the conducting core and two ferrite wafers are held by two internal ground plates that form a positioned assembly. One of the plates is equipped with tongues that position the parts, fitting into slits in the other ground plate. The assembly process involves stacking a pressure washer, magnet, pre-positioned assembly, and base plate inside the casing, followed by closing the device with a single electric weld. His second patent describes a miniaturized and integrated gyromagnetic device where a center conductor is mounted between a pair of dielectric wafers and ferrite conductors, defining a circular inner configuration. A pressure washer is welded to a square casing, which mounts a magnet, wafers, ferrite conductors, and a pair of ground plates to absorb thermal expansion during operation.
