Abstract: A timing architecture for a delivery unit that interfaces telecommunications media to a switching matrix. The delivery unit is functionally partitioned into a number of application modules. Transport between the modules is handled by a bus control module, with ingress buses from the application modules to the bus control module and egress buses from the bus control module to the application module. The bus control module also distributes system timing signals to each application module on these buses. The application modules each have a common bus interface that derives common local timing signals. They also each have a common local timebase that derives additional local timing signals. The bus interface is also used to deliver synchronization signals back to the bus control module.

Abstract: An improved latch system for use in a disc drive is provided including an improved means for eliminating tolerances in the parked position of the actuator arm in the landing zone on the disc. According to this system, the latch system includes latch arm having a rotary engaging portion which engages a portion of the transducer support arm or actuator arm in the disc drive to prevent movement of the transducer when the shock appears; this latch arm is directly coupled to an air vane which extends parallel to the edge of the disc in a region nearly adjacent to the actuator arm and at a distance at a center of the disc which is just greater than the radius of the disc so that the vane extends partially along an arc or a line near to the edge of the disc. The latch arm and vane are arranged so that in the presence of disc rotation, wind generated by the disc presses against the vane, and the vane moves away from the disc.

Abstract: A spindle for a disc drive which can be assembled without the use of adhesives is disclosed. Stator electromagnets are encapsulated in a plastic overmold. The stator is clamped to the base with a clamp spring arrangement. An offset between the stator surface and the base flange is covered by a clamp spring such that binding of the clamp spring by a fastener allows for an adjustable biasing force to secure the stator in place. The magnet and flux shield are attached to the rotor sleeve by an easily positioned retaining ring. An elastic foam washer provides a controlled force to secure the magnet and flux shield in place on the rotor. A second elastic foam washer and a shield provide a controlled biasing force to hold magnetic fluid and magnetic poles to the rotor. Bearings are laser welded to the rotor and the shaft to rotatably mount the rotor about the shaft.

Abstract: A data bus controller is provided. The data bus controller comprises an ingress interface that receives single data streams of encoded data. A multiplexer is connected to the ingress interface and combines the single data streams into a broadcast data stream of encoded data. An egress interface connected to the multiplexer transmits the broadcast data stream. An arbiter is connected to the multiplexer. The arbiter generates control data for controlling the multiplexing of the single data streams and transmits control data to the multiplexer.

Abstract: A latch system for use in a disc drive is provided wherein a latch system comprises a latch arm having an engaging portion for engaging an engaging transducer support arm for a disc drive to prevent movement of the transducer, and a wind vane that extends partially along an arc or a line near to the edge of the disc. The latch arm and vane are arranged so that in the presence of disc rotation wind presses against the vane, and the vane moves away from the disc. In order to make the vane effective and create sufficient torque or force against the surface of the vane, the top surface of the disc drive housing is depressed in the region of the disc which is upstream from the location of the vane, where by upstream is meant that the rotation of the disc causes wind to be generated which flows under the top portion of the housing and then impacts against the vane.

Abstract: A hard disk drive assembly having a pivoted arm that moves a read/write head over a hard disk from an inside diameter to an outside diameter, and an unadjustable, one-piece crash stop that limits the movement of the arm. A first version of the crash stop is an elongated member having a smooth bottom free of projections, and having first and second through holes. The hard disk drive assembly has a base having two threaded holes. The first and second through holes of the crash stop align with the two threaded holes when the crash stop is placed on the base. Screws are disposed in the first and second through holes and are threadably engaged with the two threaded holes in the base. The screws, when tightened, lock the crash stop in a precise location. In this version, one of the screws passes through a very closely-fitting precision round hole in the one-piece crash stop. That screw acts, in effect, like a locating pin. This version can be used without modifying the existing base of the hard disk drive assembly.
