| 20080250629 | Assembly and method for installing a disc clamp - The application discloses an assembly tool for installing a disc clamp on a spindle hub. In the illustrated embodiments, the assembly tool includes a head including an inner portion, an intermediate portion and an outer portion configured to install a disc clamp on a spindle motor assembly. In the illustrated embodiments, the inner portion includes a raised portion and datum surface that interface with the spindle hub to align the spindle hub for installation of the disc clamp. | 10-16-2008 |
| 20080256791 | Fixturing a head spindle assembly with an expanding collet - An apparatus and associated method is provided for precisely positioning a datum surface of a component. The apparatus has a housing defining a tooling datum surface. A collet is supported by the housing that is selectively operable between a retracted mode and an expanded mode. In the retracted mode a clearing disengagement is defined with the component. In the expanded mode a contacting engagement with the component is defined. The contacting engagement and a simultaneous longitudinal force transferred by the contacting engagement to the component pressingly engage the datum surfaces together. The apparatus further has a bias member exerting the longitudinal force and urging the collet to the retracted mode. | 10-23-2008 |
| 20090158583 | Head gimbal assembly (HGA) connector pad alignment jig - A head gimbal assembly (HGA) connector pad alignment jig is disclosed. One embodiment provides an HGA testing jig for holding an HGA, the HGA testing jig including an opening at a location of the HGA connector pads. In addition, an HGA testing apparatus including a disk for testing the HGA and a controller with a plurality of pin connectors for providing control information to the HGA during a testing process. Thus, the present technology provides an alignment adjuster for adjusting the location of the pin connectors with respect to the connector pads to ensure a good electrical connection between the HGA connector pads and the pin connectors. | 06-25-2009 |
| 20090211083 | Method and Assembly For Extracting And Installing Dual In-Line Memory Module Cardlets - A method and a tool assembly for engaging and disengaging a cardlet housing electronic components from a computer environment. The cardlet, in a preferred embodiment is a dual in-line memory module (DIMM) cardlet. The tool comprises a carrier having a handle on one end and a plurality of retention features and engaging members on an opposing side. The carrier release mechanism is secured to the carrier and the engaging members such that activating the carrier release mechanism moves the engaging members from a first to a second position such that engagement and disengagement of the carrier and said cardlet housing electronic components can be achieved. In addition, a removable latch release member is also secured to the carrier, the release member having a durable tip for engaging and disengaging latches on the computer cardlet without damaging the cardlet or its surrounding sensitive components. | 08-27-2009 |
| 20090260225 | MANUFACTURING APPARATUS OF A HEAD GIMBAL ASSEMBLY - A bending apparatus of a head gimbal assembly includes a suction unit configured to attract the head gimbal assembly, a movement unit configured to move a long tail connected to a terminal part, a stopper against which the moved long tail is butted, a transmission type optical sensor configured to detect that the long tail is positioned to the stopper, a tail holder configured to hold a part of the long tail on a work table, a roller configured to compress the terminal part against the tail holder and to bend the terminal part relative to the long tail at a right angle, and a controller configured to control, based on a detection result of the transmission type optical sensor, a movement of the tail holder to the work table and a movement of the roller to the tail holder. | 10-22-2009 |
| 20090300907 | Method for manufacturing magnetic disk unit - Embodiments of the present invention provide a method for manufacturing a magnetic disk unit, the method permitting easy and efficient introduction of a low-density gas into the enclosure. According to one embodiment, an enclosure of the magnetic disk unit has a gas inlet and a gas outlet, each of which is provided with a filter. When the enclosure is filled with helium, the mass flow rate of helium being supplied to the gas inlet is detected and the mass flow rate of helium being supplied to the gas inlet is controlled according to the thus detected mass flow rate of helium. | 12-10-2009 |
| 20160163346 | IN-SITU ANNEALING OF A TMR SENSOR - A computer program product according to one embodiment includes a computer readable storage medium having program instructions embodied therewith. The program instructions area executable by a data processing system having at least one processor to cause the data processing system to apply, by the data processing system, a current to a lead of a tunneling magnetoresistance (TMR) sensor for inducing joule heating of the lead or a heating layer, the level of joule heating being sufficient to anneal a magnetic layer of the sensor; and maintain, by the data processing system, the current at the level for an amount of time sufficient to anneal the sensor. | 06-09-2016 |
