Abstract:

An ultrasound information processing system is disclosed in which ultrasound image data is packetized into ultrasound information packets and routed to one or more of a plurality of processors for performing image processing operations on the ultrasound image data, the ultrasound information packets being routed according to entries in a host-programmable routing table. A common distribution bus is coupled between packetizing circuitry and dedicated input buffers corresponding to each processor for distributing the ultrasound information packets, and a common output bus to is used to transfer processed image data from the processors to an output device. The disclosed ultrasound information processing system architecture allows for a high throughput rate for accommodating real-time image processing operations, while also allowing for ready programmability and upgradability. Advantageously, the disclosed ultrasound information processing system may be readily upgraded by coupling additional processors to the common distribution bus and the common output bus and by reprogramming the routing table to include the additional processors as destinations for the ultrasound information packets. The disclosed ultrasound information processing system architecture also provides for added field reliability by providing for an optional spare processor coupled to the common distribution bus and the common output bus, wherein upon detection of a failure of one of the existing processors, the optional spare processor may be loaded with a copy of a program being run by the failing processor and the routing table may by automatically modified to redirect ultrasound data packets from the failing processor to the spare processor.

International Classification:

G11B

US Classification:

360 9701

Abstract:

A magnetic recording disk based on conventional disk technology has both an extremely smooth top surface and high coercivity, and is incorporated in a contact recording disk file which requires an extremely smooth head-disk interface and a disk with high coercivity. A superfinished untextured NiP coating on a disk substrate is oxidized to form a NiO film. The NiO film permits the subsequently sputter deposited magnetic layer to have much higher coercivity, which enables the disk to be used in contact recording applications. The NiO film and the later deposited layers making up the disk, including the top protective overcoat, conform to the smooth surface of the polished NiP, thus preserving the extremely smooth surface of the top layer of the disk, which is required for the head-disk interface in contact recording disk files. In the preferred process for forming the NiO film on the substrate, the substrate is annealed in air at a temperature below that which would cause the NiP film to crystallize.

International Classification:

G11B 2300

US Classification:

428 64

Abstract:

A thin film metal alloy magnetic recording disk has an improved protective overcoat which is both wear resistant and which creates a low level of stiction in a rigid disk file. In a preferred embodiment the overcoat is a film of essentially amorphous carbon or hydrogen-containing carbon with relatively small amounts of additives of iron (Fe), tungsten (W) or tungsten-carbide (WC). The structure of the overcoat is a relatively smooth planar carbon surface with discrete clusters of the additives which project slightly above the smooth carbon surface. The specific additives to the carbon overcoat improve the wear resistance of the disk and permit the sliders to contact the disks in contact start/stop (CSS) operation without damage to any of the disk file components.

International Classification:

B05D 136

US Classification:

427554

Abstract:

A process for creating an array of bumps to texture a brittle nonmetallic surface, such as a glass substrate for data recording disks. The texturing process uses a laser to provide pulses of proper energy fluence to the brittle glass surface to produce a plurality of raised bumps in the surface. The bump creation is accomplished without unwanted micro-cracking or ejection of surface material by limiting the laser pulse fluence to a value in a narrow operating region discovered below the abrupt thermal shock fluence threshold for the brittle nonmetallic surface material. The process is also applicable to other brittle surface textures, such as those intended for use as "stamping surfaces" for the contact reproduction of the negative of a surface pattern, such as an optical disk.

International Classification:

C23C 1304

US Classification:

427248A

Abstract:

This invention is concerned with a process for bonding a durable low surface energy polymeric coating to a metal or oxide surface. The metal or oxide surface is first treated with an alkali, thereby maximizing the hydroxide ion concentration on the surface, and then in a rigorously dry state with a rigorously dry fluorinated material to form the polymeric coating. The fluorinated material has the formula Rf -- O -- (CH. sub. 2). sub. n -- SiX. sub. 3 wherein Rf is a fluorinated lower alkyl group, n is an integer from 2 to 10, and X is a halogen, cyanide or alkoxy group.

Abstract:

A protective coating is formed on an integrated circuit device by coating the device with a solution of acetylene terminated, branched polyphenylene prepolymer material and heating the material to form a thermoset crosslinked polymer layer. Selectively patterned portions may be provided when, after the coating step and prior to the heating step, the steps of imagewise exposure to radiation and rinsing with an organic solvent are carried out.

US Classification:

428 653

Abstract:

A thin film metal alloy magnetic recording disk has an improved protective overcoat that creates a low level of static friction in a contact start/stop disk drive. The disk has an amorphous carbon overcoat containing a transition liquid metal interlayer (TLMI). The carbon overcoat is formed by depositing an initial amorphous carbon layer to a first thickness, then depositing an interlayer material of a low-melting point metal or metal alloy (such as In or In--Nb) while maintaining the temperature of the disk substrate above the melting point of the interlayer material, and then depositing a top additional layer of amorphous carbon. Because the initial carbon layer presents a nonwetting surface, the interlayer material "balls up" on the carbon and forms discontinuous spheres of the interlayer material. The additional top layer of carbon bonds to the initial carbon layer and to the metal or metal alloy spheres. The completed disk protective overcoat presents a continuous but textured surface of amorphous carbon for the head-disk interface in the disk drive.
