Jean Claude Peuzin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for increasing the operating frequency of a magnetic circuit and corresponding magnetic circuit
    Patent number: 6940383
    Abstract: A process for increasing the frequency of operation of a magnetic circuit. In the process, gaps are formed in at least one section of the magnetic circuit. The gaps lower the permeability of the magnetic circuit and increase in particular the frequency of magnetic resonance and make possible the use of higher frequencies. Applications of the process include the manufacture of inductors, transformers, components, magnetic heads, etc . . .

  • Method of polarization of a ferroelectric material
    Patent number: 4086124
    Abstract: In a method of polarization of a ferroelectric material having a Curie point at a temperature T.sub.c, the material is brought to a temperature above T.sub.c, subjected to a temperature gradient and then returned to a temperature below the Curie point. No electric field is applied, because the temperature gradient itself has been found to produce ferroelectric polarization under the described circumstances.

  • Optical wave guide having distributed gyrotropy
    Patent number: 4047801
    Abstract: The wave guide is constituted by a film layer C.sub.1 of magnetizable material having a constant refractive index n.sub.1 and placed between two media having refractive indices of lower value than the index n.sub.1. The layer C.sub.1 has two flat parallel surfaces which separate the layer C.sub.1 from the two media which have lower refractive indices and is constituted by a plurality of adjacent regions forming parallel layers, the gyrotropy of at least two of these regions being different.

  • Optical wave guide for carrying out phase-tuning between two modes of light propagation
    Patent number: 4032217
    Abstract: A dielectric film layer C.sub.2 is deposited on a transparent film layer C.sub.1 in which two optical transverse TE and TM modes propagate and is provided with a metallic coating having reflecting properties on the face which is not in contact with the layer C.sub.1. The thickness of the layer C.sub.2 is such that phase-tuning is effected along the direction of propagation of the two TE and TM waves within the wave guide as essentially constituted by the layer C.sub.1.
