Abstract: A fan motor of a cleaner capable of exhibiting a high output is provided. The fan motor includes a shroud disposed to cover a fan, a rotor fixed to a shaft, and a stator disposed opposite to the rotor in an axial direction with a predetermined gap therebetween. The stator includes a substrate on which a bearing is installed and a plurality of armatures disposed around the bearing. A coil is formed in such a way that a flat wire having a rectangular cross-section is bent to a short side thereof to be wound around an iron core.

Abstract: A base of a disk drive apparatus includes a bottom plate portion, a pivot post, and a recessed portion. A lower surface of the bottom plate portion includes a first lower surface and a second lower surface. The first lower surface is arranged to extend perpendicularly to the first and second axes on a side of the recessed portion on which the first axis lies. The second lower surface is arranged to extend perpendicularly to the first and second axes on an opposite side of the recessed portion with respect to the first axis and at a level higher than that of the first lower surface. The first lower surface includes a projecting portion arranged adjacent to the recessed portion, and arranged to project in a direction away from the first axis.

Abstract: A system including a printed circuit board having a plurality of vias, a first integrated circuit mounted on a first surface of the printed circuit board, and a casing mounted on a second surface of the printed circuit board. The first surface of the printed circuit board is opposite to the second surface of the printed circuit board. Each of the plurality of vias has (i) a first end extending to the first surface of the printed circuit board and (ii) a second end extending to the second surface of the printed circuit board. The first integrated circuit is in thermal contact with the first ends of the plurality of vias. The casing is in thermal contact with the second ends of the plurality of vias.

Abstract: An optical disc drive device has a metallic exterior casing and an internal unit to be housed in the exterior casing. The internal unit further includes an optical pickup unit for performing recording or reproduction of information signals on an optical disc, and a printed wiring substrate on which a connector electrically connected to the optical pickup unit and serving for transmission and reception of electrical signals from and to external electronic equipment is mounted. The exterior casing has an opening for allowing the connector to be exposed outside, the printed wiring substrate has a ground pattern formed to surround the connector, and a fringe portion of the opening of the exterior casing and the ground pattern are in electrical contact with each other. Thus, radiation noise from around wiring lines contained in the optical disc drive device or the like is reduced.

Abstract: A disk-enclosure cover for a low-profile, hard-disk drive (HDD). The disk-enclosure cover includes a substantially flat, plate-like portion that includes a periphery, and a peripheral flange that is disposed at the periphery. The peripheral flange includes a recessed portion that is configured to be recessed from a SATA connector in proximity to the SATA connector. In addition, the recessed portion is configured to allow a top portion of the SATA connector to be disposed in close proximity to the peripheral flange when the SATA connector is seated on a receiving connector of the low-profile HDD.

Abstract: A drive system including: a printed circuit board; a first integrated circuit mounted onto the printed circuit board; a drive assembly case that is connected to the printed circuit board; and a first thermal interface material thermally coupled between i) the printed circuit board and ii) the drive assembly case. Thermal energy generated by the first integrated circuit is dissipatable by the drive assembly case through the first interface material.

Abstract: A spindle motor includes a stator unit and a rotor unit supported to be rotatable with respect to the stator unit. The stator unit includes a stator, a base portion including a through hole, and a circuit board. The circuit board includes a connection portion to which a conductive wire from the stator is connected after passing through the through hole, and an extending portion arranged to extend from the connection portion. A lower surface of the base portion includes a recess portion arranged to accommodate the connection portion, and a groove portion arranged to extend from the recess portion to have the extending portion arranged therein. A bottom surface of the groove portion includes a protrusion portion arranged to protrude downwards.
