Granted: 2001-11-20
Abstract: A communications path not using a deterministic signal frame structure is generally not provided with a performance monitoring system or error detection system. A communications path may be provided with performance monitoring by using known Alarm Indication Signal (AIS) type monitoring on the path but scrambling traffic signals in a scrambler (4) to avoid them being mistaken for an AIS. At the receiving end (8) of the path (5), monitoring means (9) is used for monitoring the received signals for the presence of an AIS, followed by a descrambler (10) to unscramble said received signals before transmitting them to a receiving piece of CPE (12). An adverse state detector may also be provided, to avoid the scrambler (4) scrambling traffic signals so that they look like an AIS.

Abstract: A method of reducing the burden on database administrators when integrating information from a database system with a computer system over a computer network is disclosed.  Rather than requiring the database administrator to express the meaning of database attribute names in a new language, the database administrators needs only to specify mappings between different database schemas by creating database example files.  The database example files contain a common body of information values stored using the corresponding attribute names of the different database schemas.  The database example files then become the basis for generation of a translation map between the computer system and the remote database system.  Then, information queries from a user are translated with the translation map to the database schema of the remote database system.

Abstract: An augmenting circuit (153) augments an embedded PN sequence of 2N-1 chips generated by an N-bit LSSR (111) to provide an augmented PN sequence of 2N chips and an augmented PN sequence of 2N chips shifted by D chips. The augmenting circuit comprises a N-bit counter (123) that counts a plurality of clock bits. The N-bit counter provides a pre-carry signal that changes state when the counter's index equals a predetermined value and provides a value of the N-k most-significant-bits (MSB) of the index. A logic circuit (107,119) receives the plurality of clock bits and responds to the pre-carry signal to gate the plurality of clock bits. A comparator (135) receives the value of the N-k MSB and a threshold value to output a select signal that controls a multiplexer (139).

Abstract: According  to  the present  invention,  in  a  heating apparatus having a viscous heater using viscous fluid for heating cooling water, when an engine rotational speed is lower than a set rotational speed relative to a temperature of viscous fluid, a viscous clutch is turned on to transmit a rotational driving force of the engine to a rotor of the viscous heater.  In this way, a shearing force is applied to the viscous fluid in the heat-generating chamber,  and the circulating cooling water is heated by generated heat of the viscous fluid to improve the heating capacity.  When the engine rotational  speed  is  higher than the set  rotational  speed relative to a temperature of viscous fluid, a viscous clutch is not turned on.  Therefore, the rotational driving force of the engine is not transmitted to the rotor of the viscous heater, so that the shearing force is not applied to the viscous fluid to prevent the oil temperature of the viscous  fluid from increasing excessively higher than 200 °C.

Abstract: Lorsque les matériaux de remblais sont déplacés et nivelés une première fois par la machinerie traditionnelle, il reste des imperfections qu'il faut corriger manuellement avec un râteau.    Dans la présente invention, il est question d'une grille de nivellement de finition fabriquée de tubes métalliques disposés à angle, adaptable à tout genre de godet.     Cette grille est équipée de lames de ressort et d'un cylindre hydraulique lui permettant de changer de position.     Lorsque l'on tire les matériaux de remblais, les tubes qui sont assemblés à angles remplissent  les vides au centre de la grille sans débordement extérieur. Par contre, lorsque la grille est poussée, les matériaux de remblais sont déplacés de chaque côté de celle-ci.     Cet  appareil  permet  d'effectuer  un travail  parfait  de nivellement de remblais et par le fait même élimine le dur travail manuel de finition au râteau.

Abstract: The present invention is directed to a method for improving the ash characteristics of a paper wrapper for a smoking article and for improving the ash characteristics of the smoking article itself.      Specifically, it has been unexpectedly discovered that the ash characteristics of a paper wrapper are noticeably improved when a calcium carbonate filler having a median particle size of from about 0.15 microns to about 0.5 microns is incorporated into the paper. Paper wrappers made with the calcium carbonate particles of the present invention have superior ash characteristics in comparison to paper wrappers incorporating calcium carbonate particles of larger or smaller sizes. Further, the ash characteristics of the paper are improved without having to alter total filler levels in the paper.

Abstract: Un flux décapant exempt de composés organiques volatiles, à base de résine, se compose de 40 à 50 % en poids d'une résine epoxy liquide, de 25 à 30 % en poids d'un diluant liquide non volatil, de 20 à 33 % en poids d'un acide carboxylique polyvalent et de 2 à 3,5 % en poids d'un agent thixotrope. Il n'y a pas de solvants ou de composés organiques volatils dans le flux, qui peut s'évaporer au cours du processus de refusion. Les acides carboxyliques se présentent sous forme de poudre et se trouvent en suspension dans le mélange epoxy dans lequel ils restent sous forme de particules solides jusqu'à ce qu'il soit chauffés dans le processus de refusion de la brasure. Une pâte à souder exempte de composés organiques volatiles provenant du flux se compose de 40 à 95 % en poids de particules de brasage, et de 5 à 60 % en poids du flux décapant exempt de composés organiques volatils. L'agent thixotrope améliore la capacité d'impression de la pâte à souder sur les cartes de circuit imprimé. Un fil de brasage comprent ce flux exempt de composés organiques volatils comme âme du fil ainsi qu'une enveloppe externe d'alliage de brasage. Le flux à base de résine epoxy, exempt de composés organiques volatiles active efficacement la poudre de brasage et le contact de cuivre au cours du processus de refusion tout en se durcissant afin de laisser un résidu solide, sec mais souple sur une carte de circuit imprimé. Il n'y a pas d'émanation de composés organiques au cours du processus de refusion.

Title: Improvements in or relating to the addressing of liquid crystal displays
Inventor: SURGUY PAUL WILLIAM HERBERT
IPC: G02F1/133
Filed: 1996-05-13
Granted: 2002-04-09
Abstract: A liquid crystal device of the kind in which individually addressable regions are set- table to different optical states in response to drive waveforms is described. The waveforms are used to cause the material in different re- gions to remain set in its existing optical state or to change to another state in dependence upon data to be input to the device, and they are pulse-like in nature and of predetermined am- plitude and duration. The operating speed of the device in response to said waveform is im- proved by causing the profile of the waveforms to depart from the usual squared profile. In one example the waveforms are caused to have substantially triangular leading and/or trailing edges and the profile causing the material to re- main set in its existing optical state differs from that causing the material to change into another optical state.

Title: A voice transmitting apparatus, a voice transmitting method, and a voice band signal transmitting system using the same apparatus or the same method
Inventor: HAYANO MASASHI
IPC: H04L47/43
Filed: 1998-11-10

Abstract: A voice band signal is compression-encoded at a voice compression-encoding portion and is assembled into a cell at a cell assembling portion. Conversely, the voice band signal is disassembled at a cell disassembling portion and is decoded at a voice compression-decoding portion.  When, from both of up and down data judging portions, receiving a judgement of coincidence of the voice band signal with a signal at the time when the line is unused, a timer counts a continuation time.  When the continuation time exceeds a protection time, a protection time judging portion causes the cell assembling portion to stop the cell transmission.  When, from either of the up and down data judging portions, receiving a judgement of no coincidence with the signal at the time when the line is unused, or when the continuation time does not exceed the protection time, the cell assembling portion is directed to transmit the cell.
