Patent CA-2096996-C (CA)
Title: Surface acoustic wave device
Inventor: YATSUDA HIROMI
IPC: H03H9/10
Filed: 1993-05-26
Granted: 1996-11-05
Abstract: A surface acoustic wave device has a package and a surface acoustic wave element mounted therein face down.          The package includes a side wall comprising linear inner side surfaces close to respective outer side surfaces of the surface acoustic wave element and recesses defined where the inner side surfaces of the side wall intersect at respective inner corners. When the surface acoustic wave element is inserted into the side wall along the inner side surfaces thereof, the corners of the surface acoustic wave element do not engage the side wall because of the recesses.          Therefore, the outer side surfaces of the surface acoustic wave element may be positioned very closely to the inner side surfaces of the side wall. The surface acoustic wave device may be reduced in size, and the surface acoustic wave element may have input and output electrode pads and ground pads positioned highly accurately with respect to electrode pads on the bottom plate of the package.

Abstract: L'invention est un dispositif rapide de détection de données et d'extraction de signaux d'horloge qui est incorporé à un signal de données multiniveau dans lequel la forme d'onde du signal reçu est échantillonnée à des emplacements périodiques présélectionnés (fig. 1) et les échantillons ainsi obtenus sont comparés à des valeurs établies représentant les niveaux prévus à ces emplacements (D0, D1-D16). Ceci permet de détecter la présence de données. De plus, si cette détection se produit à intervalles périodiques, la détection d'un signal de synchronisation (signal d'horloge) est signalée (42, 44, 51-54). Une concrétisation de l'inventions à double fonction de détection est également divulguée et décrite.

Abstract: Burst SRAMs designed for operation at a given data rate corresponding to the frequency of a first clock signal but capable of operation using a higher frequency clock signal.  The burst SRAMs are preferably incorporated into the cache memory of a second level cache coupled to the processor bus in a computer system, where the computer system is preferably based on a 66-MHz P5 microprocessor.  A cache controller, preferably incorporated within a memory controller, controls operation of the second level cache memory by providing the address load and address advance signals. The burst SRAMs are capable of recognizing the faster clock pulses, as well as the shorter pulses asserted on the address load and address advance signals.  The address control signals are asserted and then negated during consecutive clock cycles of the faster clock signal, so that the burst SRAMs effectively operate at the same data rate corresponding to the lower frequency clock signal.

Title: Pipeline padding apparatus with rotary feeder
Inventor: OSADCHUK MARK
IPC: B07B1/00
Filed: 1994-04-25
Granted: 2005-02-08
Abstract: An improved pipeline padding apparatus includes a separator for separating fine material out of spoil which is piled along side an excavation, an elevator for transporting spoil to the separator, and a pair of spaced-apart guide projections for guiding spoil into the elevator. The spaced-apart guide projections form a substantially open bottom extending the width of the elevator between the guide projections. A conveyor is provided to transport the separated fine portion of the spoil back into the excavation, thereby padding the pipeline.  The separator, the elevator, the guide projections, and the vehicle are all mounted on a support vehicle. According to one aspect of the invention, one or more rotary feeder assemblies is mounted to the guide projections for assisting in moving spoil through toward the elevator. The rotary feeder assemblies have a low profile so that spoil material and rocks do not become stuck as they move toward the elevator. In another aspect of the invention, the motor of the tracked support vehicle is mounted above and forward of the elevator, which helps reduce the amount of dust that the motor is exposed to during operation. According to another aspect of the invention, the guide projections may be configured to allow excess spoil to flow underneath in such a manner as to smooth out a path for the tracks of the support vehicle.

Abstract: A diagnostic system for diagnosing states of circuit elements is described, wherein scannable circuits can be scanned without disturbing the state of unscannable circuits of violating protocols of busses on which unscannable devices are attached.  One unscannable device is a standardized microprocessor.  A processor interface circuit is coupled between the microprocessor and scannable processor circuits, via a processor bus, to insulate the scannable processor circuits from the unscannable microprocessor.  The processor interface circuit is also scannable, including memory elements which affect the bus, by preventing a scan when the bus is in use.          A scan is prevented through the use of a maintenance request signal from a scan controller to the processor interface circuit, and one or more maintenance approval signals from the processor interface circuit to the scan controller.

Title: Oxidizing gas detector paper
Inventor: NAKANO NOBUO
IPC: G01N31/22
Filed: 1994-06-24
Granted: 2004-10-12
Abstract: A sheet of paper is immersed in a reacting solution prepared by dissolving p-n-butoxyaniline, an ultraviolet absorber and polyalcohol in an organic solvent. Then, the organic solvent is allowed to evaporate. Thus, the p-n-butoxyaniline and ultraviolet absorber are spread over the sheet of paper by using the water absorbed in the polyalcohol that serves as a medium for reaction. When the paper is exposed to chlorine or other oxidizing gas, the p-n-butoxyaniline colors, aided by the water absorbed in the, polyalcohol, to form a trace of reaction according to the concentration of the oxidizing gas. Because the ultraviolet absorber prevents the reaction between the p-n-butoxyaniline and light, no discoloration-induced sensitivity drop occurs during storage.

Abstract: A cable television network is supplemented with optical fibers and fiber termination units to communicate additional downstream digital signals and upstream signals. A drop unit for each customer premises is provided in the drop cable.  The drop unit demodulates downstream signals and selects for delivery to the customer premises only those downstream signals addressed to the customer premises, modulating the selected signals using binary phase shift keying (BPSK) which provides relative immunity to noise for forwarding the signals to the customer premises.  Upstream BPSK signals from the customer premises are demodulated and remodulated in the drop unit to isolate the customer premises wiring from the rest of the network.

Granted: 2006-09-05
Abstract: The retaining device of a wire-section dispenser has a tongue-like first retaining element and a second retaining element which form boundaries for a gap. The second retaining element can be moved out of a rest position into a clamping position, which narrows the gap, and back again. When the second retaining element is located in the rest position, a stapling wire is advanced into the gap and then fixedly clamped by displacing the second retaining element into the clamping position. A cutting element, which severs the continuous stapling wire into wire sections, is synchronously moved with the second retaining element.   The staple guide of a stapling head engages with its carry-along member, the wire section and moves it in the direction of rotation, overcoming the retaining force in doing so.

Abstract: A method and system for updating a replicated database in a foreign and home telecommunication network system to improve call setup time and system availability in a  foreign  region  for  roaming  customers  is  disclosed.          Customer records are updated in a visitor database contained in a foreign region within the signaling system of foreign telecommunications  network.   Information concerning the updated database record is transmitted from the visitor database through the signaling network of a home country to a home database which contains the replicated version of the visitor database record in the foreign region.  A field is added to the database record corresponding to a version number of the database record so as to identify the record referenced by queries of calls  in progress.   The home database record at the home country is changed to reflect changes in the visitor database at the foreign region by using the version number sequence while maintaining at all database sites the older version of the database record for query access until after completing the processing of all previous calls querying the database record.
