  • Patent number: 11948725
    Abstract: A wire-wound coil component is an electronic component including a core main body, such as a molded body, containing a magnetic powder resin in which a resin serves as a binder, and an oxide film covering at least a portion of the surface, such as the lower surface, of the core main body. The electronic component further includes an external electrode including a base layer formed on the surface of the oxide film. The base layer is a metal layer having high affinity for oxygen.

  • Patent number: 11915854
    Abstract: A wire coil component includes a shaped article, a wire wound around the shaped article, and terminal electrodes to which the ends of the wire are connected. The shaped article is formed from a magnetic resin containing a binder resin and a magnetic metal powder and has a thermal expansion coefficient of about 12 ppm/K or more and about 16 ppm/K or less (i.e., from about 12 ppm/K to about 16 ppm/K) from ?55° C. to 150° C.

  • Patent number: 4837883
    Abstract: In a method of washing clothes by a washing machine having a washing tub including a fixed drum mounted on the upper side of the tub, and a movable drum disposed under the fixed drum so as to rotate horizontally. Small loads are washed by the water flow within the movable drum, while large loads of clothes are washed by water flow and the force of contact friction between the fixed drum and the movable drum to cause a twisting and rubbing wash action.

  • Patent number: 4545220
    Abstract: A washing machine having an improved pulsator which includes a skirt, vanes projecting from the skirt, and a rod-like projection located at a position offset from the center of rotation of the skirt and extended to a position higher than the vanes. The pulsator rotates in the forward and reverse directions to responsively effect satellite motion of the rod-like projection about the central axis of rotation so that highly turbulant localized water flow is established in conjunction with a vortex flow arrangement to enhance the washing capabilities of the machine.
