Shinichi Wakasugi 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).

  • Patent number: 7333318
    Abstract: A multilayer capacitor 1 has a laminated body 20 configured by laminating a plurality of dielectric substrates 2 each having a plurality of internal electrodes 3 and 5 formed on its main surface and a capacitance component is generated between the facing internal electrodes 3 and 5. The dielectric constant of the dielectric substrate located at a central portion of a lamination direction of the laminated body 20 is lower than that of the dielectric substrate 2 located at the edge of the lamination direction.
    Type: Grant
    Filed: September 11, 2006
    Date of Patent: February 19, 2008

  • Patent number: 7133274
    Abstract: A multilayer capacitor including a base body, which is a dielectric substance; and a plurality of electrode layers, which is laminated in the base body and has a plurality of divided electrodes, in which there are at least three or more kinds of electrode layers having different number of electrodes, and the electrode layer having the most electrodes is interposed between the other electrode layers. The multilayer capacitor achieves high withstand voltage and high reliability with no damage to the size reduction and high capacitance of the capacitor and a mold capacitor having the multilayer capacitor built-in.
