An electronic device may include an electronic circuit, a heat sink thermally coupled to the electronic circuit, and spaced apart cooling fins extending from the heat sink. Each cooling fin includes a circuit board and a cooling device mounted thereon. The cooling device may have a conductive trace layer on the circuit board defining an electromagnet, a mounting member extending upwardly from the circuit board, a fan blade coupled to an upper end of the mounting member to be movable in a rocking motion about an axis defined by the mounting member, and a permanent magnet carried by the fan blade and responsive to the electromagnet.

A valve portion has a sleeve and a valve body inserted into the sleeve. A solenoid portion includes a stator core having a magnetic attraction core, a sliding core, a magnetic flux passage suppressing portion, a yoke having a bottom portion, a side surface portion, and a thin wall portion, a coil portion, a plunger, and a magnetic tubular base portion. The base portion has a first tubular portion in which a first outer peripheral surface of the sleeve is press-fitted into inside and fastened to the first outer peripheral surface, a flange portion that has an outer diameter larger than the outer diameter of the first tubular portion, is arranged on an outer side in a radial direction of a second outer peripheral surface of the magnetic attraction core, and is caulked and fixed to the thin wall portion while being in contact with the yoke inside the yoke.

A multilayer substrate includes a stacked body including a principal surface and insulating base material layers made of a thermoplastic resin that are stacked, and a coil including coil conductors. The coil includes a winding axis in a stacking direction. The coil conductors includes a first coil conductor closest to the principal surface, and a second coil conductor adjacent to or in a vicinity of the first coil conductor. The second coil conductor includes a wide portion of which a line width is larger than a line width of the first coil conductor. The wide portion includes an overlapping portion that overlaps with the first coil conductor, and a non-overlapping portion that does not overlap with the first coil conductor, when viewed from the stacking direction. The non-overlapping portion is curved to be closer to the principal surface than to the overlapping portion.

This invention relates to a washable multi-component magnetic floor mat with a hidden base component. The floor mat contains a textile component and a base component. The textile component and the base component are attached to one another by magnetic attraction. The magnetic attraction is provided by incorporation of magnetic particles in both the textile and base components. The textile component is designed to be soiled, washed, and re-used, thereby providing ideal end-use applications in areas such as building entryways. The present invention eliminates the need to wash the base component of the floor mat which results in environmental, cost and labor conservation. Alignment and deployment of the textile component with the base component in an efficient manner is also described herein.

A coil assembly includes: a bobbin; a coil including a winding around the bobbin; a yoke attached to the bobbin; and a connection terminal electrically connected to the winding. The connection terminal is a press-fit terminal that includes a terminal portion projecting perpendicularly from the bobbin outward in an axial direction of the bobbin. The yoke is arranged on a side of the bobbin that is opposite to the terminal portion in an axial direction of the terminal portion, and supports the press-fit terminal.

In the actuator, the first end plate part of the first cover member in the support body is layered on one side in the first direction of the holder and faces the first yoke of the movable body from one side in the first direction. The second end plate part of the second cover member in the support body is layered on the other side in the first direction of the holder and faces the movable body from the other side in the first direction. Thus, the first viscoelastic member interposed between the movable body and the first end plate part in the first direction properly contacts with the movable body and the first end plate part. The second viscoelastic member interposed between the movable body and the second end plate part in the first direction properly contacts with the movable body and the second end plate part.
