Title: Transistor a effet de champ a grille isolee presentant des barrieres de schottky passivees vers le canal
Inventor: GRUPP DANIEL E
IPC: H01L29/872
Filed: 2003-08-08
Abstract: L'invention concerne un transistor comprenant un canal (220) de semi-conducteur disposé près d'une grille (270) et dans une trajectoire électrique entre une source (250) et un drain (260). Ce canal et au moins un élément parmi la source ou le drain sont séparés par une couche d'interface (230, 240), de sorte à former une jonction source/drain-couche d'interface-canal, dans laquelle un niveau de Fermi du canal de semi-conducteur est décalé dans une région proche de la jonction, et la jonction présentant une résistance de contact spécifique inférieure à 1000 Φ-νm2. La couche d'interface peut comprendre une matière de passivation, notamment un nitrure, un fluorure, un oxyde, un oxynitrure, un hybride et/ou de l'arséniure du semi-conducteur du canal. Dans certains cas, la couche d'interface comprend essentiellement une monocouche configurée pour décaler le niveau de Fermi du semi-conducteur du canal, ou une quantité de matière de passivation suffisante pour terminer les liaisons pendantes dans leur totalité ou un nombre suffisant de liaisons pendantes du canal de semi-conducteur, afin d'obtenir une stabilité chimique de la surface. En outre, la couche d'interface peut comprendre une couche de séparation constituée d'une matière différente de la matière de passivation. Lorsqu'elle est utilisée, la couche de séparation présente une épaisseur suffisante pour réduire les effets des états d'espace induits par le métal dans le canal de semi-conducteur.

Title: Method and apparatus for control of an electric power system in response to circuit abnormalities
Inventor: NELSON WILLIAM CHRISTIAN TRACY
IPC: G05D17/00
Filed: 2003-10-17
Abstract: A methodology and related system apparatus is provided for using and coordinating the use of information conveyed over communications to most efficiently and flexibly respond to abnormalities to reconfigure and restore service to end customers in commodity distribution systems in a manner to enhance the reconfigurability of the distribution system, e.g. circuit reconfiguration in an electrical power distribution system. Methodology is also provided to appropriately allocate system resources of the distribution system when so desired, e.g. to prevent the potential overloading of electrical power sources. In one illustrative arrangement, the methodology is characterized by resources at each node and communications of source allocation data or messages to other nodes to request and establish an appropriate allocation of system resources. In a preferred arrangement and especially useful for larger distribution systems, “teams” of nodes are defined in the distribution system having associated switching controls with the various teams communicating amongst each other to “negotiate” or work out the most efficient and expeditious reconfiguration of the system in response to fault conditions and other circuit abnormalities.

Abstract: A turbulence-generating cementing sub (16) adapted to be coupled in screw-threaded end-to-end engagement between two sections of a string of well liner (15) and run through a cased oil well and cemented therein at a selected depth. The cementing sub (16) is a short section of pipe having two sets of rigid flow-directing ribs or vanes (31, 33) welded or machined on the outer surface thereof. One set of ribs (31) are angled on the sub to change the direction of a flowing cement slurry causing it to swirl around the sub in one direction. The adjacent set of ribs (33) are angled to the opposite side of the sub axis to interrupt at least a portion of the swirling cement slurry and cause it to swirl around the sub in the opposite direction thus generating a zone of turbulence in the flowing cement slurry between two strings (13, 15) of well pipe. The rigid ribs (31, 33) also act as centralizers for the inner pipe or liner (15).
