  • Patent number: 11380476
    Abstract: In a multilayer coil component, a ferrite element body includes a first element body portion and a second element body portion adjacent to each other in an axial direction of the multilayer coil, in which a dielectric constant of the second element body portion is lower than a dielectric constant of the first element body portion, and a magnetic permeability of the second element body portion is higher than a magnetic permeability of the first element body portion. The inventors newly found that the first element body portion and the second element body portion contribute to coil characteristics when a coil winding portion is provided to extend over the first element body portion and the second element body portion. In the multilayer coil component, desired coil characteristics can be obtained by adjusting proportions of the first element body portion and the second element body portion in the ferrite element body.

  • Patent number: 11372327
    Abstract: The present invention provides a molding apparatus that performs a molding process for molding a composition on a substrate using a mold, including a holding unit configured to hold the substrate, and a control unit configured to control the molding process, wherein the control unit starts a process for pressing the mold against the composition on the substrate while the substrate is held by the holding unit with a first holding force, causes the holding unit to hold the substrate with a second holding force smaller than the first holding force after the process is started, and maintains the holding of the substrate by the holding unit with the second holding force until completion of filling of the composition on the substrate into the mold.

  • Patent number: 11367559
    Abstract: The inventors have newly found that, even when a composition of a first element body portion and a composition of a second element body portion are different from each other, a high bonding strength at an interface between the first element body portion and the second element body portion can be obtained when both the first element body portion and the second element body portion contain Zn2SiO4 as a constituent component. That is, when the first element body portion and the second element body portion contain Zn2SiO4, a bonding strength at the interface is improved compared to a case in which the first element body portion and the second element body portion do not contain Zn2SiO4.
