  • Patent number: 12640297
    Abstract: The present invention discloses a magnetic positioning holder for positioning a cylindrical storage container, comprising a main body and two magnetic strips. The main body features two guide surfaces on one side in the thickness direction, each adjacent to one of the sides of the main body, wherein each guide surface is concave toward the other side of the main body in the thickness direction to from an arc. Each magnetic strip is embedded in the main body and corresponds to each guide surface along the thickness direction of the main body. The distance between each magnetic strip and its corresponding guide surface, defined as the magnetic attraction distance, decreases from each width side toward the central part of the main body along the width direction. Thus, the storage container can be guided to move toward the central part of the main body in the width direction and positioned.

  • Patent number: 12614654
    Abstract: To suppress an increase in DC resistance due to surface roughening in a coil component including a spiral pattern. A coil component manufacturing method includes: a first step of forming a conductor layer including a spiral pattern spirally wound in a plurality of turns; a second step of selectively roughening an upper surface and an upper region of a peripheral-direction side surface of the spiral pattern; and a third step of forming an insulating resin layer so as to embed therein the conductor layer, and the first to third steps are repeatedly performed. Since the upper surface and the upper region of the side surface of the spiral pattern are selectively roughened, it is possible to suppress an increase in DC resistance due to excessive roughening at the lower region of the side surface.
