Abstract: Embodiments herein disclose a mounting device for attaching a quad to an extender during a hard disk drive manufacturing process. Specifically, the mounting device includes a quad clamp for fastening the quad onto the surface of the mounting device and an extender clamp for fastening the extender to the mounting device. A human operator may apply an adhesive material onto a contact surface of the extender that faces the quad. Using a pressing unit, the mounting device slides the quad until the quad couples to the extender at the contact surface with the adhesive. Once the quad and extender are connected, the clamps may be disengaged so that the combined quad/extender structure may be removed from the mounting device. Using the mounting device to mechanically mount the quad onto the extender mitigates misalignment between the quad and the extender relative to a bonding process that relies on the human operator.

The parameter monitored has the tendency to vary over time (and space), and the processing means ensure that control output is not based upon the difference between an originally monitored parameter value and a reference value but rather between a prediction generated value (accounting for passage of time or spacital difference) and the reference value.

Abstract: A method and apparatus for producing a metal component from a non-dendritic, semi-solid metal alloy slurry involves the use of a graphite agitator that is functionally equivalent to conventional metal rod agitators, and has the additional advantage of having a very low surface wettability, whereby labor and expenses associated with removing a metal alloy skin formed after withdrawal of the agitator from a metal slurry is eliminated or at least substantially reduced. The invention also provides an improved process and apparatus for producing a metal component from a non-dendritic semi-solid metal slurry by transferring the slurry to a cooling vessel for subsequent cooling and raising of the solids content without agitation after the slurry has been formed with agitation in a first vessel, whereby more rapid cooling of the slurry and increased production rates are achievable.
