Abstract: A metal electrode formed on an oxide superconductor for electric connection to the oxide superconductor, includes a first layer of Ag in direct contact with the oxide superconductor, and a second layer formed on the first layer. The second layer is formed of noble metal excluding Ag.     The metal electrode can be formed by forming a first layer of Ag to cover a whole surface of the oxide superconductor layer, and forming a second layer of noble metal excluding Ag, to cover a whole surface of the first layer, thereby to form a double metal layer, and patterning the double metal layer so as to form a metal electrode composed of the double metal layer.

Title: Perceptual coding of audio signals
Inventor: BRANDENBURG KARLHEINZ
IPC: G10L19/02
Filed: 1990-10-09
Granted: 2001-01-16
Abstract: A method is disclosed for determining estimates of the perceived noise masking level of audio signals as a function of frequency. By developing a randomness metric related to the euclidian distance between (i) actual frequency components amplitude and phase) for each block of sampled values of the signal and (ii) predicted values for these components based on values in prior blocks, it is possible to form a tonality index which provides more detailed information useful in forming the noise masking function. Application of these techniques is illustrated in a coding and decoding context for audio recording or transmission.

Title: Appliance manufacturing and transport fixture
Inventor: SPARKS GENE A
IPC: D06F39/00
Filed: 1991-05-28
Granted: 2001-07-17
Abstract: A fixture for appliance manufacturing and transport of the assembled appliance supports vertically movable components of the appliance at differing elevations during manufacturing and continues to at least partially support the components during the transport after assembly. A particular use of the fixture is in the manufacture of a washing machine which has a suspended wash tub and drive assembly and an outer cabinet. The fixture is composed of a main support and a cabinet support with the main support being vertically movable relative to the cabinet support, yet held by the cabinet support in a fixed horizontal position. The wash tub and drive assembly is supported during use by a suspension system connected between the wash tub and cabinet and with the use of the fixture, a portion of the weight of the wash tub is supported at all times during the assembly process and during shipping, relieving the cabinet from bearing that weight. Further, with the tub support being movable relative to the cabinet support in a vertical sense, the wash tub can be elevated relative to the cabinet for purposes of attaching the suspension system between the tub and cabinet thus greatly facilitating the manufacturing process.

Abstract: L'invention est un système vidéotex interactif à traitement réparti et à stockage d'informations sur des images vidéo dans des noeuds installés dans un système de distribution par câble d'émissions de télévision. Ces noeuds sont couplés au câble d'alimentation du système de distribution par câble. Chaque noeud du système reçoit d'un centre de traitement régional une copie substantiellement identique de ces informations et de données connexes. Les téléviseurs installés dans les domiciles des utilisateurs qui sont reliés à un noeud donné sont en interaction directe avec les informations sur les images vidéo stockées dans ce noeud plutôt qu'avec les informations stockées au centre de traitement régional ou à un autre emplacement éloigné, ce qui permet au système d'afficher rapidement des images de qualité photo et des graphiques complexes, ainsi que de reproduire des sons, sur les téléviseurs des utilisateurs en réponses à des instructions transmises par ces derniers. Les noeuds peuvent également être utilisés pour décomprimer les signaux de télévision et transmettre les signaux résultants aux téléviseurs domestiques connectés au système.

Title: Slant plate type compressor with variable displacement mechanism and method of controlling the capacity thereof
Inventor: TERAUCHI KIYOSHI
IPC: F04B27/18
Filed: 1992-04-10
Granted: 1997-12-09
Abstract: In a slant plate type compressor with a variable displacement mechanism, the stroke of the piston changes in response to the change of the slant angle. The relative distance of the piston from the valve plate when in top dead center position varies within a certain range in response to the change of the stroke of the piston. A detecting device disposes adjacent the cylinder detects the top dead center position of the piston in the compression space. The piston's stroke length is related to the detected top dead center position, and once the piston's stroke length is known, this information can be used to determine whether capacity control is required.

The bottom of the container includes a web extending between a central portion adjacent the longitudinal axis of the container and a generally perpendicular ring segment in each of the downward projections for providing enhanced stability against deflection during entry of the filling liquid into the container which aids in the prevention of bottom failure from stress cracking associated with the rigors of the filling procedure.
Patent CA-2115464-C (CA)
Inventor: O'FARRELL WILLIAM G
IPC: G06F9/44
Filed: 1994-02-11
Granted: 1998-12-15
Abstract: In sequential object oriented languages such as C++, a mechanism is provided to permit multiple asynchronous processing operations without compiler modifications, language extensions or special pre-processing.  A specially adapted pointer converts a procedure call into an asynchronous task thread,  while returning an expected response to permit a calling program to continue processing.  The returned value can be either discarded or converted to a future variable if the calling program requires the result of the separate processing on the asynchronous thread.  The invention can be used in parallel multiprocessor environments and in uniprocessors having parallel processing characteristics.
Patent CA-2119048-C (CA)
Title: Method of controlling the quantity of printing ink available for transfer from an anilox roller, reconditioning of used anilox rollers, and reconditioned anilox roller structure
Inventor: RESLOW LEIF F
IPC: B41F31/08
Filed: 1994-03-15
Granted: 1998-10-20
Abstract: To maintain required or desired ink transfer capability of an anilox roller (6) after wear and tear caused, for example, upon engagement of the surface of the roller against a doctor blade (7a, 7b) of a chambered inking unit (7), the ink receptor depressions or cells (14,514) in the surface of the roller are formed with a depth which is substantially greater than that necessary for the volumetric dimension for required or desired retention of ink suitable for transfer upon printing with a predetermined print density. Before application of printing ink thereto, the cells are filled with a removable filler material (20), for example copper, plastics such as polyethylene, epoxy, wax or the like. After the surface of the strips or ridges or cell walls becomes worn, a portion of the filler material is removed, for example by vaporization, by a laser, etching or the like, to reconstitute the original volume for ink retention. The change in print density upon printing, as the surface wears, is abrupt (Fig. 4: tB) and, when that change is determined, the volume-reconstituting step is carried out. If the surface of the roller itself is a layer which is readily machinable, for example made of copper, the initial depth of the cells (14,514) may be for the initial requirement of ink retention. The layer thickness is then originally made thick enough so that, upon sensing of the abrupt change in print density, for example based on time or on printing results, the depth of the cells still present in the roller can be increased, e.g. by a laser, to obtain and reconstitute the volumetric dimension for desired ink retention.
