Subhash Chand Kashyap 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).

  • Lead iron tungstate capacitive transducer, relaxor material therefor and method of manufacture of said relaxor material
    Patent number: 7354565
    Abstract: The present invention discloses a relaxor material lead iron tungstate which has been synthesized in doped and undoped conditions by single and two step heat treatment. The relaxor material is seen to exhibit almost negligible hysteresis and a transducer made thereby shows pressure measurement capability over a wide range from 0.5 MPa to 415 MPa with accuracy of ±0.05%.
    Type: Grant
    Filed: December 16, 2002
    Date of Patent: April 8, 2008
    Assignees: Council of Scientific & Industrial Research, Indian Institute of Technology - Delhi
    Inventors: Kamlesh Kumar Jain, Vinay Kumar, Subhash Chand Kashyap
