  • Patent number: 10388448
    Abstract: A multilayer coil component includes an element body including soft magnetic metal powders and a coil disposed in the element body. The coil includes a plurality of internal conductors electrically connected to each other. The plurality of internal conductors are separated from each other in a first direction and are adjacent to each other in the first direction. An average particle diameter of the soft magnetic metal powders located at an inner side of the coil when viewing from the first direction is larger than an average particle diameter of the soft magnetic metal powders located between the internal conductors adjacent to each other in the first direction.

  • Publication number: 20190198227
    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.

  • Publication number: 20190198232
    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: 10182626
    Abstract: Silicone is placed between an upper die and an injection-pressing rubber-lid upper die, and the silicone injection passage is pressurized by the injection-pressing rubber-lid upper die. With this, the silicone is caused to flow into an injection port through the silicone injection passage. Then, sequentially through the injection port and the disc silicone-flow passage, the silicone is caused to flow toward an inner periphery of a silicone injection space. Further, the silicone flows between both circumferential sides of the silicone-flow deflection region. In this way, the silicone flows in a peculiar manner in conformity with a shape of the silicone-flow deflection region.

  • Patent number: 8433832
    Abstract: A control equipment with a built-in communication apparatus is provided which realizes a delay required for communication without a software intervention while at the same time reducing a load of the communication processing. The control equipment with a communication apparatus includes: a communication device to communicate with a plurality of destinations; and a decision device to determine a mode requiring a reception completion interrupt and a mode not requiring the reception completion interrupt. If the decision device decides that the reception completion interrupt is not necessary, the communication device transmits data to one or more destinations and also virtually transmits data to a second destination different from the first intended destination.
