Okikuni Takahata 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: 7679482
    Abstract: An inductor includes a first magnetic substance core which has a middle leg, a first outer leg, a second outer leg, and a body portion interconnecting the middle leg, the first outer leg and the second outer leg, and a second magnetic substance core which is arranged to be opposed to the first magnetic substance core. A first conductor is arranged in a first space which is formed by the middle leg, the first outer leg, part of the body portion, and the second magnetic substance core. A second conductor is arranged in a second space which is formed by the middle leg, the second outer leg, part of the body portion, and the second magnetic substance core. The middle leg is formed with a region which is lower in height than the first outer leg, in the same direction as the longitudinal direction of the first outer leg.

  • Patent number: 7648774
    Abstract: An electromagnetic noise suppressor including a ferrite film is formed by regularly arranging constituents such as magnetized grains or one analogous to that. In the ferrite film, the constituents have at least one of the uniaxial anisotropy and the multiaxial anisotropy. The ferrite film has the magnetic anisotropy or the magnetic isotropy. The ferrite film is formed by a plating method in the presence of a magnetic field.
