Title: Ferromagnetic-metal-based powder, powder core using the same, and manufacturing method for ferromagnetic-metal-based powder
Inventor: NAKAMURA NAOMICHI
IPC: H01F1/26
Filed: 2002-03-22
Abstract: An iron-based powder including a heat-resistant insulate coating and a powder core are suggested. A paint containing silicone resin and pigment is added to a raw material powder primarily containing a ferromagnetic metal, especially, iron, agitation and mixing are performed and, thereafter, a drying treatment is performed so as to form a coating containing silicone resin and pigment on the surface of the iron-based powder. The ratio of the silicone resin content to the pigment content in the coating is preferably 0.01 or more, but less than 4.0 on a mass basis. The pigment is preferably at least one selected from the group consisting of metal oxides, metal nitrides, metal carbides, minerals, and glass. The paint may be sprayed to the iron-based powder in a fluidized state. A coating containing at least one of Si compounds, Ti compounds, Zr compounds, P compounds, and Cr compounds may be formed as a lower layer of the aforementioned coating.

Patent CA-2385364-A1 (CA)
Title: Systeme laser a longueurs d'onde multiples
Inventor: LAURENT-LUND CHRISTIAN
IPC: H01S3/06
Filed: 2000-09-20
Abstract: La présente invention concerne un système et un procédé permettant d'obtenir un guide d'onde optique plan et intégré émettant dans plusieurs longueurs d'onde avec une large gamme de longueurs d'onde, ayant une commande stricte sur les positions absolues, et surtout relatives, des longueurs d'onde émises, ainsi que des largeurs de raie étroites. L'indice de réfraction effectif n¿eff? d'un mode laser dans un guide d'onde est au moins en partie déterminé par le recouvrement physique, le facteur de confinement, entre le mode laser et le profil de l'indice de réfraction de l'âme du guide d'onde. Lorsque des guides d'onde possèdent des profils d'indice de réfraction bien définis, en réglant les dimensions transversales de l'âme du guide d'onde on règle le profil d'indice de réfraction et, par conséquent, le facteur de confinement et n¿eff?. Selon la présente invention, au moins deux lasers en guide d'onde sont formés dans lesquels les éléments réflecteurs constituant la cavité du laser possèdent une réflectivité dépendante du spectre qui dépend de l'indice de réfraction effectif, n¿eff?, ressenti par un mode laser à la position de l'élément réflecteur. Au moyen d'éléments réflecteurs identiques, tels que des réseaux de Bragg, pour les différents lasers, on peut ajuster la longueur d'onde des lasers en réglant les dimensions transversales relatives, telles que les largeurs, desdits lasers. Ceci permet un réglage relatif précis des lasers et élimine les incertitudes sur les périodes relatives des réseaux de Bragg. La dépendance de n¿eff? de la largeur w, n¿eff?(w), est de préférence grande de manière à couvrir une large gamme de longueurs d'onde simplement au moyen d'une faible variation de la largeur des guides d'onde. Ainsi, des lasers différents ont à peu près les mêmes dimensions.
Patent CA-2385844-A1 (CA)
Title: Label switched routing system and method
Inventor: OPREA DAN
IPC: H04L12/56
Filed: 2002-05-10
Abstract: A packet routing/switching system and method are provided by which label switched routing is performed within a hierarchy of LSP/FA-LSPs defined/provisioned in a network of interconnected nodes. Rather than transmitting an entire label stack with an LSP label for each LSP/FA-LSP in the hierarchy, at a given node in the network, a single LSP label is transmitted together with a components label which contains a list of component identifiers which do not inherently identify LSP/FA-LSPs, but from which the full LSP/FA-LSP labels can be determined locally at each node using previously distributed information described in detail below. The list of component identifiers is a shorthand way identifying to adjacent nodes the identity of the LSP/FA-LSP hierarchy without transmitting the entire LSP labels and thus significantly reducing overhead.      The single label which is transmitted is the label of the LSP/FA-LSP of which the given node forms a part.

Title: Mobile telephone with pager mode
Inventor: HEATLEY DAVID JOHN TAYLOR
IPC: H04M1/7243
Filed: 2001-03-28
Abstract: A mobile telephone is arranged to detect when its battery voltage has fallen such that only the lowest segment of the tour segment battery charge level bar of its LCD display is showing, and, in response, to transmit a "Restricted Delivery Mode"  message to a predetermined network destination number, and then to disable its transmit function. An audio signal is generated to alert the user, and a warning message is displayed, e.g. Battery Low, Message Mode. Restricted Delivery Mode is a selectable option via the telephone's menu. The mobile network, upon receipt of such a "Restricted Delivery Mode" message, sets a "Restricted Delivery Mode" flag in the user's profile. For an originating call the profile is accessed in the normal manner, and, if that flag is set, the network sends, e.g. a "Receive Only - Leave Message" announcement to the caller.

Title: Apparatus and method for coding/decoding channels in a mobile communication system
Inventor: KIM JAE-YOEL
IPC: H03M13/00
Filed: 2002-02-07
Abstract: A CDMA mobile communication system determines the number of input information bits (5 bit) and the number of symbols to be punctured, and encodes/decodes the input information bits (5bits). A transmitter encodes the input information bits into 16 coded symbols with a first order Reed-Muller code, and punctures four coded symbols from the 16 coded symbols so as to generate a codeword having the minimum distance. A receiver then receives punctured coded symbols, i.e., the codeword, and inserts zero (0) bits at the punctured positions. Further, the receiver calculates reliabilities between the zero-inserted coded symbols with all of first order Reed-Muller codewords, and outputs input information bits for the coded symbols corresponding to the highest reliability.

According to a second embodiment ions are released from the ion trap in reverse order of mass to charge ratio with the ions having the largest mass to charge ratio being released first. By appropriate release of the ions from the ion trap it is possible to ensure that substantially all of the ions arrive at the pusher electrode 1 at substantially the same time. According to both embodiments it is possible to achieve a duty cycle approaching 100% across a large range of mass to charge ratios.

IPC: B67D1/00
Filed: 2001-08-09
Abstract: La présente invention concerne un système de traitement d'eau placé sous le compteur. L'eau provenant d'une source d'alimentation extérieure, telle qu'une conduite d'eau municipale, est fournie au domicile de l'usager. Un préfiltre (41) destiné à supprimer les sédiments, des composés organiques et certains polluants est d'abord prévu. Après ce préfiltre, l'eau entre dans un système d'osmose (42) qui comprend une membrane osmotique. Cette membrane osmotique inverse filtre et évacue les impuretés et les très petites particules de façon à fournir une eau hautement purifiée. Le flux de sortie de ce filtre à osmose inverse est stocké dans un réservoir d'eau (44). On retire l'eau de ce réservoir en libérant une vanne appropriée lorsque l'usager souhaite boire cette eau. Lorsque l'eau sort du réservoir, elle passe à travers une cellule d'électrolyse (36) possédant une pluralité de plaques. Le courant passe entre ces plaques, et par voie de conséquence, à travers l'eau qui s'écoule entre ces plaques. Ce phénomène produit plusieurs effets sur l'eau, notamment une création d'oxygène dans cette eau, l'introduction d'électrons libres dans cette eau, ainsi qu'une amélioration du goût, et une affinité de cette eau pour accepter d'autres minéraux. Après ce passage dans la cellule d'électrolyse, l'eau peut passer par une étape de traitement final (45) après lequel elle est fournie au robinet en vue d'une consommation par l'usager. Le flux d'électricité vers les plaques est commandé en trois modes de fonctionnement. Pendant le premier mode de fonctionnement, la puissance est délivrée aux plaques pendant une durée sélectionnée après laquelle le commutateur est d'abord pressé. Cette durée sélectionnée étant écoulée, la commande de puissance vers les plaques est reliée à l'activation du commutateur lui même pendant un deuxième mode de fonctionnement. Si le commutateur reste ouvert pendant une longue durée, les commandes électroniques entrent dans un troisième mode de fonctionnement durant lequel la puissance est automatiquement coupée vers la cellule d'électrolyse.
