  • Patent number: 10807646
    Abstract: A suspension tower is coupled to a front side member at a portion of the front side member located frontward from a front pillar. A frontal vehicle structure includes a coupling member including a front end coupled to the suspension tower and a rear end coupled to the front pillar. The coupling member includes an outer panel and an inner panel that form a closed cross-sectional structure. The outer panel includes a weak portion arranged between a joined portion of the coupling member joined to the suspension tower and a joined portion of the coupling member joined to the front pillar.

  • Patent number: 9343101
    Abstract: A hard disk drive is described, including a low-profile disk clamp to tied-shaft spindle/spindle motor assembly, in which a clamping nut is threaded onto a threaded spindle sleeve and a stationary shaft screw, or tied-shaft, penetrates through the HDD cover and into a shaft. The disk clamp may include a central opening for centering about the sleeve by way of the outer diameter of the clamping nut mating with the outer diameter of the clamp opening.

  • Publication number: 20150015995
    Abstract: Approaches to maintaining hard disk drive spindle motor rigidity and performance in low profile HDD devices comprise using an enclosure base with a bottom opening in which a separate motor cup is fitted and configured to support the spindle motor. The motor cup may then be fabricated using a different material than the enclosure base, such as a material having a higher modulus of elasticity than that of the base. Furthermore, a magnetic motor cup may be used to substitute for the thrust yoke typically used with conventional spindle motors.

  • Patent number: 8189290
    Abstract: A spindle motor includes a shaft arranged concentric with as a central axis and extending in a vertical direction, a rotor unit arranged to rotate about the central axis, a stator including a base member and a magnetic member fixed to the base member and axially opposed to the magnet. The magnetic member includes an opposing portion axially opposed to the magnet so that a magnetic attracting force is generated between the opposing portion and the magnet and a protrusion portion protruding downwards from the opposing portion. The base member includes a recess portion, and the protrusion portion of the magnetic member is fixed within the recess portion.
