  • Patent number: 7966855
    Abstract: A process of forming a shaped composite material is provided which includes the steps of providing a composite strip having a substantially rigid substrate with a major surface and a polymer overlying the major surface of the substantially rigid substrate. The process further includes shaping the composite strip with a mandrel to form a shaped composite piece having a shape substantially defined by the shape of the mandrel, wherein during the shaping step the major surface of the composite strip is substantially maintained in one plane.

  • Patent number: 7958637
    Abstract: A shaft is held in place within a bore of a housing with a band of resilient material that is located between the shaft and the housing and has a series of projections extending radially inwards. The shaft surface has a first part that lies closer to the longitudinal axis of the bore than a second part, when the shaft and housing are assembled. The shaft is initially inserted into the resilient band, which is held within the bore, such that the first part of the shaft surface is oriented towards one of the projections of the resilient band. In this orientation of the shaft, the projection is not compressed. By orienting the second part of the shaft surface, the projection is brought under compression and the shaft is held firmly within the bore.

  • Patent number: 7957103
    Abstract: A thin component such as the actuator arm (10) of a hard disk drive, is mounted on a pivot or pin (31), such as the pivot assembly of the hard disk drive, using a ring (32), e.g. a tolerance ring, having one or more projections (35), wherein the engagement of the component (30) and the ring (32) is such as to apply a force to the component (30) in a direction which is inclined to both the radial and axial directions of the pivot or pin (31). The pivot or pin (31) has a flange onto which the component (30) is pressed by the axial component of the force generated by the ring on the component. The edge of the ring (32) remote from the component (30) is engaged with a stop element, e.g. another flange (34) of the pivot or pin (31).
