Patents by Inventor Takafumi NOGI

Takafumi NOGI 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: 10790089
    Abstract: A stacked capacitor includes a laminate; first to fourth external electrodes; a first capacitor portion, a second capacitor portion, and a third capacitor portion which are arrayed in the laminate from a first surface toward a second surface along a laminating direction. The first capacitor portion and the third capacitor portion each have a capacitance larger than that of the second capacitor portion. Inductor components of the first capacitor portion and the third capacitor portion are different in physical length from each other and are connected in parallel between the first external electrode disposed on a first end surface and the third external electrode disposed on a first side surface and between the first external electrode and the fourth external electrode disposed on a second side surface.
    Type: Grant
    Filed: May 26, 2017
    Date of Patent: September 29, 2020

  • Patent number: 9947474
    Abstract: A multilayer capacitor includes a first grounding internal electrode including a first grounding electrode having a lead-out part led to one side surface of a stacked body, and a second grounding electrode having a lead-out part led to the other side surface; a second grounding internal electrode including a third grounding electrode which overlaps the first grounding electrode and has a lead-out part led to the other side surface, and a fourth grounding electrode which overlaps the second grounding electrode and has a lead-out part led to one side surface; and a signal internal electrode disposed between the first and second grounding internal electrodes, wherein the first and second grounding electrodes and the third and fourth grounding electrodes have, at their adjacent opposed sides, corners curved as seen in a plan view in the stacking direction, respectively, the corners being each located opposite to the corresponding lead-out part.
