Inventors:

Thomas R. Stone - Pleasanton CA

Assignee:

Plus Development Corporation - Milpitas CA

International Classification:

H03M 100

US Classification:

250231SE

Abstract:

An improved optical encoder is disclosed. The encoder includes a moveable scale with alternating equally dimensioned opaque and translucent regions extending generally perpendicular to the locus of scale movement; and a light source, a mask and a rectangular photodetector array having at least a pair of generally symmetrical, rectangular photodetector areas, the longitudinal dimensions of those areas being disposed relative to the regions of the scale at a predetermined acute angle of rotation. The mask defines at least two series of equally spaced apart elongated phase shifted openings aligned to be generally parallel with the regions of the scale, the mask openings being aligned at the same angle of rotation as the major lineal dimensions of the photodetector areas. The mask openings are substantially coextensive with the rectangular photodetector areas. The light source, mask and photodetector array are commonly mounted on a single axis of rotation in a rotatable stationary housing.

International Classification:

G11B 545
G11B 2120

US Classification:

360106

Abstract:

An improved actuator apparatus is employed in a hard disk drive device for positioning read/write heads over tracks on a data storage disk of the disk drive. The actuator apparatus includes an all plastic C-block assembly providing the actuator apparatus with a reduced weight, lower inertia and better damping characteristic which enable improved dynamic performance. The C-block assembly includes a body portion and a pair of tapered support arms extending from the body portion in a parallel orientation. The support arms each have a suspension for a read/write head staked thereto within a mounting surface aperture at a distal end of the arm. The mounting surface aperture is configured to have a non-circular shape to facilitate staking of the read/write head to the support arm and enable construction of the C-block assembly out of plastic. The non-circular shape of the mounting surface aperture additionally enables swaging within the aperture of the plastic support without causing the plastic support arm to break or crack.

Assignee:

Quantum Corporation - Milpitas CA

International Classification:

G11B 554

US Classification:

360105

Abstract:

An aerodynamically powered release latch mechanism is provided for a fixed disk drive. A disk clamp for clamping a single data storage disk to a spindle hub comprises a centrifugal airflow pumping structure, such as radially and axially extending, generally L-shaped turboblades, for increasing the level of a vane deflecting airflow as the disk rotates. The vane deflecting airflow releases an aerodynamically released actuator latch mechanism.

International Classification:

G11B 5596

US Classification:

360 7704

Abstract:

A micro-Winchester disk drive subsystem includes a data block sequencer, cache memory and interface for a host computing machine. The drive includes a base and a plurality of non-removable directly rotated disks forming data storage surfaces. A balanced rotary head transducer actuator is mounted to the base for a plurality of data transducer heads among a multiplicity of concentric data tracks formed on each data storage surface of each of the disks. The track following servo system includes a position encoder coupled between the actuator structure and the base, prerecorded data track centerline information at a radially outermost region and at a radially innermost region of each data surface, and a temperature sensor for sensing temperature of the base at the vicinity of the position encoder. An actuator driver circuit is connected to supply electrical driving current to the actuator structure; and, a single, time divided multi-tasked digital including an analog to digital converter is connected to receive the position information from the position encoder, centerline information from the disk surfaces read by the data transducer and temperature sensed by the temperature sensor during a calibration operation in one phase of its operational cycle, the other phase being devoted to supervision data block handling functions of disk drive data block sequencer cache memory and interface. During track following operations, centerline information is derived from information obtained in the calibrate operation.

Assignee:

Quantum Corporation - Milpitas CA

International Classification:

G11B 554

US Classification:

360105

Abstract:

An airlock latch assembly for restraining a disk drive actuator when the disk is not spinning and the disk drive is subjected to a rotational shock force includes a latch member meshably engaged with a counter inertia member by gear teeth provided on each member. The latch member and the counter inertia member are each characterized by a moment of inertia, the ratio of which is determined by the gear ratio of the respective gear teeth. The latch assembly also restrains the actuator in its proper position when the disk drive is subject to linear shock forces.

Assignee:

Paccar Inc. - Bellevue WA

International Classification:

B62D 2700

US Classification:

180 8915

Abstract:

A tilt-cab truck with the cab independently suspended on the main frame. A power device for tilting is connected to the cab and the frame at pivots spaced away from the main cab pivot. On each side of the truck a front suspension bell crank is pivoted to the cab by a main pivot and has an arm extending substantially horizontally back to a pivotal connected to the main frame, with a crank arm extending down from the rear and bearing on one end of a horizontal front air spring that is secured to the main frame at its other end. A leveling valve assembly for maintaining cab height relative to the frame is connected to the front air springs and to a source of air pressure. An anti-roll structure is rigidly connected at each end to the bell crank and extends down below it and then laterally across to the other side of the truck. A pair of lower latch assemblies are each secured to the main frame near the rear of the cab, and a pair of upper latch assemblies are each releasably secured to a lower latch assembly. A pair of horizontal rear links are each pivotally connected at a forward end to the cab and at a rear end to an upper latch assembly, and a pair of rear air springs are each mounted on an upper latch assembly with an upper end bearing against the cab.

Inventors:

Assignee:

PACCAR Inc - Bellevue WA

International Classification:

B62D 2706

US Classification:

180 8914

Abstract:

A mounting and latching system for a cab-over-engine type truck, wherein the cab is pivotal about an axis at the front of the cab and frame, includes mounting devices at the left and right, at the rear of the cab. Each frame-attached mount has two angled surfaces for receiving complementarily shaped cab-attached mounts and centering the cab's rear on the frame, in normal operation. When the truck frame twists due to unevenness of the surface over which the truck is moving, the cab above remains substantially undeformed with one rear mount continuing to bear against the frame surface and the other separated from the frame. The latching system maintains the cab's rear latch at both mounts even during such movement, by means of a spring biased pivoted hook which is permitted considerable movement. Latching and unlatching, for tilting of the cab, are accomplished via a hydraulic arrangement by which the latching hook is automatically articulated in several directions to cause unlatching and swinging away of the hook so that the cab rear can be lifted. The hydraulics of the latch are preferably tied into a hydraulic cab tilt system, so that when hydraulic pressure is applied by the operator, the latches first disengage, then the cab lifts, and the reverse when the cab is lowered back to the frame.
