摘要： The disclosed signal generating apparatus and method is suitable for use in combination with a PM receiver to provide a standby signal for a signal processor. The standby signal system includes a clipper connected to the receiver IF; a coherent amplitude detector coupled between the clipper and a gain controlled amplifier; and a trigger circuit coupled between the coherent amplitude detector and the signal processor. The trigger circuit provides a standby signal in response to the level of the output signal of the coherent amplitude detector passing through a predetermined threshold level in response to the clipper limiting on a selected signal-to-noise ratio which occurs before the information signal becomes undesirably weak.

摘要： A digital storage system of the Winchester or hard disk drive type has the annular, hard aluminum disks mounted coaxially around the drive motor. A central fixed aluminum shaft has the motor stator coils centrally mounted on it, and an aluminum disk mounting sleeve is mounted to the shaft by bearings located above and below the motor stator. To accommodate the difference in thermal coefficients of expansion between the steel cylinder forming the outer periphery of the motor's rotor and the aluminum disk assembly, the outer steel cylinder of the motor rotor is bonded to the aluminum disk sleeve by means of an elastic adhesive, which permits relative expansion between the steel and aluminum parts occasioned by changes in temperature of the drive. The rotor, including its permanent magnets and outer steel cylinder, is mounted from the inner surface of the aluminum disk mounting sleeve, with the rotor in operating proximity to the stator. The aluminum storage disks and the spacers between them are clamped between the top and bottom of the aluminum mounting sleeve.

摘要： A digital storage system of the Winchester or hard disk drive type has the hard aluminum disks mounted around the drive motor. To accommodate the difference in thermal coefficients of expansion of the steel cylinder forming the outer periphery of the motor, and the aluminum disk assembly, an aluminum disk mounting sleeve is provided which extends for the full height of the disk assembly, and makes a thermal shrink fit around the steel motor cylinder, with the engagement between the two parts being limited to a section toward the center of the overlapping surfaces of the two parts. The aluminum storage disks and spacers between them have a slight clearance from, and are clamped between the top and bottom of the aluminum mounting sleeve.
