Abstract: A metal sheet with attachment points for attaching the metal sheet to a support structure has a contour cut introduced in a sheet surface of the metal sheet, wherein the contour cut extends transversely to a connection line extending between a first and a second one of the attachment points. The contour cut is positioned relative to the first attachment point such that a vibration line extending as far as the first attachment point when the contour cut is not present is interrupted by the contour cut.

Abstract: An environmental control assembly includes a housing including a base layer, a diffusor layer, and an interior space at least partially formed by the base layer and the diffusor layer. The environmental control assembly further includes a desiccant positioned within the interior space and an inlet filter that is formed from a cutout in the base layer that is covered by the diffusor layer.

Abstract: Provided is a base unit for use in a disk drive apparatus and to be attached to a cover portion to define an enclosed space to be filled with a gas having a density lower than that of air. The base unit includes a base portion arranged to extend radially and support a motor capable of rotating about a central axis extending in a vertical direction; and a lateral wall portion arranged to extend axially upward from an edge portion of the base portion. The base portion includes a part accommodating portion defined by a through hole arranged to pass through the base portion in an axial direction, and arranged to accommodate at least a portion of a predetermined part; and a seal member arranged to close an end portion of the through hole on one axial side. The base portion and the lateral wall portion include a base made of a metal; a coating portion formed by electrocoating a surface of the base with at least a resin; and at least one exposed portion where the surface of the base is exposed.

Abstract: The apparatus includes a drive base, a drive cover overlying the drive base, wherein the drive cover comprises an opening therein, and wherein the drive cover is coupled to the drive base to enclose a media within an interior of the apparatus. A snubber is overmolded onto the drive cover. The media contacts the snubber during shock events.

Abstract: A loudspeaker module emitting sound at a lateral side comprises a loudspeaker unit and a module housing comprising a lower module housing, a middle module housing and an upper module housing. A space formed by the loudspeaker unit, the middle module housing and the lower module housing is a rear sound cavity. A space formed by the loudspeaker unit, the middle module housing and the upper module housing is a front sound cavity. The loudspeaker module further comprises a cover plate which forms a cavity together with the upper module housing. The cavity is communicated with the rear sound cavity through a conducting hole. By utilizing the loudspeaker module of the present invention, superfluous space of the upper module housing can be converted into the rear sound cavity, and therefore the size of the rear sound cavity is increased, and the acoustic performance of the loudspeaker module is improved.

Abstract: An apparatus includes a first component and a second component. The second component is located at a first position. The second component includes a first connection to the first component. The first position and the first connection are configured to stiffen an electric motor assembly.

Abstract: The present disclosure relates to an apparatus that includes an electrical connector that is coupled to a housing and that extends through a feedthrough aperture in the housing. The electrical connector has an electrically insulating base that has multiple layers of electrically insulating material with electrical traces extending between the multiple layers. The electrically insulating base also has a first portion disposed in the interior cavity, a second portion disposed external to the interior cavity, and a sealing portion disposed between the inwardly positioned portion and the outwardly positioned portion. The electrical connector also includes a first plurality of electrical leads that are disposed on the outwardly positioned portion of the electrically insulating base and a second plurality of electrical leads disposed on the inwardly positioned portion of the electrically isolating base material. Each of the electrical leads is electrically coupled to a corresponding lead.

Abstract: Improved hard disk drives of the invention comprise a composite housing, wherein the composite housing comprises a base and a cover, wherein at least a portion of the composite housing comprises a laminate of at least one rigid plastic layer and at least one metal coating. Methods for forming the same are also disclosed.

Abstract: A hermetically resealable hard-disk drive (HDD) configured for recharging with a low-density gas. The hermetically resealable HDD includes a disk enclosure (DE), a magnetic-recording disk, a head-slider, an actuator, a low-density gas, a through-hole, and a plug. The DE includes a base, and a first cover and a second cover joined to the base. The second cover is disposed above the first cover. The through-hole is configurable for injection of a low-density gas into the DE. The low-density gas, having a density less than air, substantially fills the DE. The plug is press-fitted into, and hermetically seals, the through-hole. The plug is removable to allow recharging the DE with the low-density gas; and, the through-hole is configured to accept a resealing plug to be press-fit into, and to reseal hermetically, the through-hole after recharging. A method for injecting low-density gas into, and sealing, the hermetically resealable HDD is also provided.

Abstract: In a disk drive device having a double cover structure with low-density gas enclosed therein, embodiments of the present invention help to securely perform leak inspection on an outer cover and to prevent defects caused in joining the outer cover. According to one embodiment, a hard disk drive (HDD) comprises a flow amount adjuster on a base-facing side of its inner cover. Helium gas in an enclosure goes out through a ventilation hole via diffusion channel of a flow amount adjuster. The emitted helium gas remains in the space between the inner cover and an outer cover. This achieves easier detection of the leakage of helium gas from the joining section of the outer cover and prevention of emission of too much helium gas from the enclosure.
