  • Publication number: 20240096533
    Abstract: The coil component includes a coil, a first core having a first magnetic permeability, and a second core having a second magnetic permeability lower than the first magnetic permeability. The first core and the second core form a magnetic path. The coil forms two or more winding windows. The first core contacts with an entirety of one side line extending in a second direction of each of the winding windows, and protrudes from both ends of one side line of at least one of the winding windows. The second core contacts with three side lines other than the one side line of each of the winding windows. A surface resistance of the first core between two points that are 20 mm away from each other is not less than 5 ? after a high-temperature storage test. A drive frequency of the coil component is not less than 20 kHz.

  • Patent number: 10072704
    Abstract: A composite sliding bearing is disclosed. The composite sliding bearing has an inner ring, formed of split rings halved by a center in an axial direction, which has V-section inclined surfaces formed on the outer diameter surfaces of the split rings, bearing pads disposed separately on the inclined surfaces of the split rings along the outer diameter surface of the inner ring, and an outer ring on the inner diameter surface of which is formed a V-section umbrella-shaped inclined surface corresponding to the outer diameter surface of the inner ring. A radial load and axial load applied to the bearing are supported by sliding the inner diameter surface of the outer ring on the sliding surfaces of the bearing pads in a condition in which the bearing pads are fluid lubricated.
