  • Patent number: 9129737
    Abstract: A laminated inductor includes: a laminate having an insulating part constituted by non-magnetic layers, as well as a coil part constituted by conductors positioned between the non-magnetic layers; and external electrodes that are electrically connected to the ends of the coil part and positioned on the exterior surfaces of the laminate; wherein the external electrodes each have a first electrode layer whose primary constituent is Ag, as well as a second electrode layer whose primary constituent is Cu and which is positioned on the outer side of the first electrode layer and has a thickness of 4 ?m or more, and the total thickness of the first electrode layer and second electrode layer is 5 ?m or more and preferably 10 ?m or less.
    Type: Grant

  • Patent number: 9007160
    Abstract: A laminated inductor includes a laminate constituted by multiple insulator layers, and a coil conductor formed in a spiral shape inside the laminate; wherein the coil conductor has conductor patterns formed on the insulator layers, and via hole conductors that penetrate through the insulator layers and electrically connect the multiple conductor patterns; wherein conductor patterns formed on some insulator layers each represent a C-shaped pattern that includes the four corners and has an open part on one side, of a roughly rectangular shape, while a conductor pattern formed on other insulator layer(s) represents a line-shaped pattern corresponding to the open part of one side of the aforementioned C-shaped pattern of the roughly rectangular shape; and wherein an insulator layer on which the C-shaped pattern is formed, and insulator layer(s) on which the line-shaped pattern is formed, adjoin each other at least in one part of the laminate.

  • Patent number: 8669839
    Abstract: A laminated inductor includes: a laminate constituted by multiple insulator layers; external electrodes formed on the outside of the laminate; and a coil conductor formed spirally inside the laminate, wherein the coil conductor has leaders that electrically connect to the external electrodes and a coil body other than the leaders, wherein the coil conductor has conductive patterns formed on the insulator layers, and via hole conductors that penetrate through the insulator layers and electrically connect the multiple conductor patterns, wherein all of the conductor patterns constituting the coil body are either a C-shaped pattern or line-shaped pattern, wherein the coil body has a partial structure where two or more C-shaped pattern layers are stacked together successively, and wherein the number of C-shaped patterns in the coil body is greater than that of line-shaped patterns.

  • Patent number: 8528958
    Abstract: A vehicle seat accommodating device of the invention includes: a seat configured to include a seat cushion and a seat back supported so as to be tiltable with respect to the seat cushion; an accommodation recess portion formed on a floor located behind the seat; and a support unit movably supporting the seat so as to accommodate the seat in the accommodation recess portion in a state where the seat back is folded so as to be overlapped on the seat cushion, wherein when the seat is adjusted to a seating posture, both ends of the seat cushion in a vehicle width direction are mounted on wheel housings that are bloated from side walls of a vehicle body toward the inside in the vehicle width direction.
