G05B 1300

US Classification:

364176

Abstract:

A process is disclosed for determining tuning constants of a process control loop, the loop including a process control module, an actuator and a controlled process. The disclosed process includes making a series of changes to the target value of the actuator while measuring corresponding changes in the output of the controlled process. Certain calculations are applied to the information to determine the tuning constants, and the constants are applied to the control module.

International Classification:

G06F 100
G11B 5012

US Classification:

364200

Abstract:

A self contained fixed rotating disk expansion board subsystem may be installed and connected at an expansion slot location of a host computer. The subsystem includes an enclosed head/disk assembly, and circuit elements mounted on a printed circuit board which includes a connector for connecting to the control, data and address buses of the host computer at the expansion slot location. The head/disk assembly is mounted to a mounting substrate which may be the circuit board or which may be a frame to which the circuit board is also attached. Input/output routines are preferably provided to enable the host computer to make use of the subsystem without software driver modifications in the host operating system.

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.

Appl. No.:

5/964502

Inventors:

William S. Moon - San Jose CA

Assignee:

Measurex Corporation - Cupertino CA

International Classification:

B29F 302

US Classification:

264 404

Abstract:

An extruding system for the production of continuously extruded elastomer, such as tread stock for the manufacture of vehicle tires, has an extruder, a first take-away conveyor belt for conveying the extrusion as it exits the extruder, a second conveyor belt for varying the thickness or weight of the extrusion after leaving the first conveyor belt, a sensor to measure the running-weigh-scale value and a targeted running-weigh-scale value. The weight or thickness of the continuously extruded elastomer is controlled by measuring the weight of the continuous extrusion at the running-weigh-scale. The measured value is compared to the target value to obtain a control signal. The control signal is used to adjust the difference in speed between the first conveyor belt and the second conveyor belt.

International Classification:

B29D 2700
G01G 1100

US Classification:

264 402

Abstract:

Density of products produced from a foam extrusion process is controlled by measuring the thickness and the basis weight. The density is calculated and is compared to a target, or desired value, to produce an error signal. The error signal is used to control the density.

Assignee:

Quantum Corporation - Milpitas CA

International Classification:

G11B 2120

US Classification:

360137

Abstract:

An aerodynamically released safety shipping latch for a rotating disk data storage device is disclosed. A moveable airvane means adjacent a rotating disk is deflected by airflow generated by disk rotation from an at-rest biased first position to a second position. A safety latch communicating with the airvane means releases the data transducer carriage from a landing zone position when the airvane means moves to the second position in response to airflow from disk rotation.

International Classification:

G06C 116

US Classification:

395800

Abstract:

A fixed disk memory subsystem connects to digital signal buses and a power supply of a host computer and includes a printed circuit board forming a subsystem mounting substrate for mounting and connecting a head and disk assembly and drive electronics. The head and disk assembly includes a radially positionable head transducer for flying in close proximity to a data storage surface of at least one rotating data storage disk, an actuator for positioning the data transducer at concentric data tracks defined on the surface, and a DC brushless spindle motor for rotating the data storage disk. The drive electronics includes a data transducer position control circuit for controlling operation of the actuator in relation to the concentric data tracks, read/write electronics connected to the transducer, a disk user data controller for obtaining digital control signals and digital data blocks from the host computer for storage in predetermined ones of said data tracks, and for supplying digital status signals and digital data blocks retrieved from predetermined ones of said data tracks to the host computer, and a programmed digital microcontroller connected for controlling operations of said data transducer position control circuit, the disk user data controller and the interface circuit.
