Patents by Inventor Naonori Sakamoto

Naonori Sakamoto 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).

  • Infrared detection element
    Patent number: 9689748
    Abstract: An infrared detection element includes a substrate, a lower electrode layer, a pyroelectric layer, and an upper electrode layer. The lower electrode layer is fixed to the substrate, and the pyroelectric layer is formed on the lower electrode layer. The upper electrode layer is formed on pyroelectric layer. The lower electrode layer contains pores therein and has a larger thermal expansion coefficient than the pyroelectric layer.
    Type: Grant
    Filed: September 11, 2014
    Date of Patent: June 27, 2017
    Assignee: PANASONIC CORPORATION

  • DIELECTRIC ELEMENT AND PIEZOELECTRIC ELEMENT
    Publication number: 20160035961
    Abstract: A dielectric element includes a substrate, a first electrode layer on this substrate, a dielectric layer on the first electrode layer, and a second electrode layer on the dielectric layer. The first electrode layer contains lanthanum nickelate. The dielectric layer contains lead magnesate niobate-titanate represented by (1?x)Pb(Mg1/3Nb2/3)O3-xPbTiO3, where x satisfies 0.28?x?0.33. The (100) plane of lead magnesate niobate-titanate is preferentially oriented along the interface between the first electrode layer and the dielectric layer.
