  • Patent number: 10033079
    Abstract: In a non-reciprocal circuit element, electric power handling capability is improved, and leakage power between adjacent channels is reduced. In addition, balance is taken between reduction of noise between adjacent ports and an increase in insertion loss. A non-reciprocal circuit element includes a YIG ferrite (10) and a plurality of conductors (15) disposed on the YIG ferrite (10) and intersecting each other in an insulated state. A part of Y of the YIG ferrite (10) is substituted with at least any one element of Ho, Dy, and Gd, or a part of Fe of the YIG ferrite (10) is substituted with Co.

  • Patent number: 9741484
    Abstract: A laminated coil component includes a magnetic body part made of a Ni—Zn-based ferrite material and a coil conductor containing Cu as a main component, which is wound into a coil shape, and the coil conductor is embedded in the magnetic body part to form a component base. The component base is divided into a first region near the coil conductor and a second region other than the first region. The grain size ratio of the average crystal grain size of the magnetic body part in the first region to the average crystal grain size of the magnetic body part in the second region is 0.85 or less. The molar content of CuO in the ferrite raw material is set to 6 mol % or less, and firing is performed in a reducing atmosphere in which the oxygen partial pressure is an equilibrium oxygen partial pressure of Cu—Cu2O or less.

  • Publication number: 20160184331
    Abstract: An object of the present invention is to provide: a novel base that, after application to a skin surface, can rapidly form a coating film and moreover mitigates skin irritation and occurrence of odors; and an external preparation for skin. The base is used in an external preparation for skin that administers an active ingredient transdermally, and is characterized by containing at least an acrylic-based synthetic polymer and a volatile oil, wherein the base is in a liquid or ointment form prior to application to the skin surface, and the volatile oil evaporates after application of the base to form a hydrophobic coating film containing the volatile oil in the range of 0 to 60 wt % with respect to 100 parts by weight of the acrylic-based synthetic polymer.
