IPC: H04L69/40

Abstract: A method by which the each module of a token passing local area network (24) complying with IEEE standard 802.4 determines if the communication cable (28A) from which it is receiving signals is faulty and switches to a second, or redundant cable (28A). Each module transmits the same signals over both cables, but can receive signals from only one, its selected cable. In normal operations, all modules (30,36) receive signals from the same cable. Each of the modules has the capability of detecting faults in its selected cable, and of switching cables so that its second cable becomes its selected cable. Each module also has the capability of initiating the process of re-establishing the network whenever a module switches cables in response to detecting a fault. Each module in response to the process of initiating re-establishing the network, switching cables so that all modules are listening to, or receiving signals from the same cable. Each module periodically checks to determine if low level noise is present on its selected cable, and if it is, the module switches cables. A module in the listen only mode of operation will periodically check to determine if the signals it is receiving or valid. If not, it will switch cables. A module whose redundant cable has been identified as being silent, will periodically check to determine if its redundant cable remains silent.

Abstract: Integrated trading provides both automatic matching trades for trading instruments between potential counterparties and video conversational negotiated trades for trading instruments between potential counterparties using integrated keystations (202, 204, 206, 208) which are selectively connectable together. Each of the keystations (202, 204, 206, 208) includes a data input device, such as a keyboard (240) and a mouse (242), and an integrated screen display (238), with the keyboard (240) and the display (238) being shared for both the automatic matching trades effectuated by the keystation (202, 204, 206, 208) through a matching network (220) and the video conversational negotiated trades keystation (202, 204, 206, 208) through a separate conversation network (218). An integrated terminal controller (214, 216) is provided as a common interface between the keystations (202, 204, 206, 208) and the separate networks (218, 220). Transaction data is provided between given keystations (202, 204, 206, 208) in the system (200) relating to both automatic matching transactions and video conversational negotiated trading transactions through the common integrated terminal controller (214, 216) which interfaces with the separate communication paths associated with the automatic matching trades (220) and the video conversational negotiated trades (218) effectuated by the keystation (202, 204, 206, 208). The integrated terminal controller(214, 216) comprises a conversation server (252), a concentrator computer (254), the terminal computers (250) associated with the various keystations (202, 204, 206, 208) it serves, and a local area network (256) tieing them together. Initial access to both types of trades can be obtained at log on. A common ticket generation scheme for both types of trades is used so that trading tickets may be collected and communicated to a remote back office data base through the integrated terminal controller (214, 216), via the conversation server (252), irrespective of the type of trade completed.

Abstract: A magnetron sputter source providing a predetermined erosion distribution over the surface of a sputter target material is described. When the distribution is uniform, close coupling of the sputter target with the substrate to be coated is achieved, resulting in improved collection efficiency of the sputtered material by the wafer and improved film thickness uniformity. Elimination of erosion grooves provide for greater target consumption and longer target life. The cathode magnetron sputter source includes a rotating magnet assembly of a specific shape and a specific magnetic strength provides the desirred erosion distribution. The target may be dished to improve uniformity near the periphery of the wafer. 
     The resulting magnetron cathode is used for the deposition of thin films. Further applications of uniform magnetron erosion or preselected erosion include uniform or preselected magnetron sputter etch or reactive ion etch and concurrent deposition and etch.

Abstract: Optimized synchronization planning and clock distribution for a network of interconnected digital equipment is achieved by designating a network node at the highest stratum level as the master clock node, forming a group of all unassigned nodes connected to the assigned node or nodes, selecting subgroup of all nodes from the group wherein the subgroup includes all nodes having the highest stratum level of the group, limiting the subgroup to the nodes which have a desired characteristic when such nodes are included in the subgroup, determining the synchronization performance of each node in the subgroup according to a predetermined criterion, assigning one node from the subgroup as a clock timing receiver wherein the one node exhibits the best performance for nodes in the subgroup, and iterating the method at the forming step. In order to obtain an optimum synchronization plan, it is desirable to repeat the entire method described above for the complete set of nodes which are capable of being designated as a master clock node. When more than one node is capable of being considered as a master clock node, the synchronization planning method is then completed by computing the network synchronization perforamnce for each synchronization plan related to a different designated master clock node and choosing the synchronization plan which offers the best network synchronization performance as computed above.

Abstract: Circular conductor plates (2), each with a slit (4) reaching the periphery from a central hole (3), and exciting spiral coils (1) are alternately stacked and individually surrounded by magnetic frames (6). High density traveling magnetic fluxes are generated by eddy currents concentrated around the central holes (3) of the circular conductor plates (2) in response to the application of multi-phase alternating voltage in a non-magnetic pipe (7) passing through the central holes (3), with a cylindrical iron core (8) inserted, so as to convey high temperature molten metal, for instance, molten sodium used for refrigerating a high speed breeder reactor. The thickness of central portions (10) of the conductor plates (2) is increased, so as to form the radial cross-section in T-shape. Consequently, eddy currents concentrated in the central portions of the circular conductor plates are dispersed in the axial direction, owing to the increased thickness thereof, so as to prevent local overheating, to increase applied voltage, effective magnetic fluxes, and output thrust, and hence to improve the efficiency and the pecularity of molten metal conveyance.

Abstract: For calibrating an electronic measuring system with sensors which are fixed in pairs on elements of an aircraft undercarriage, loaded transversely to the longitudinal extent, and emit measuring signals which correspond to the vertical displacement between two sensor fixing points offset with respect to each other in the longitudinal extent of the elements, the sensor pairs, respectively forming a measuring point, being arranged approximately in the horizontal centre plane of the element at externally opposite positions, a process is proposed in which an own scaling factor is determined for each sensor of the sensor pair. For this purpose, the measuring signals and weights are expediently determined for two loading states of the aircraft which differ to extremes as far as possible, as well as for at least two different torsional states of the loaded element.

Other application come in that, after a natural oxide film is removed from a contact hole surface, until an upper interconnector is formed, the above mentioned protective film is temporarily formed over the exposed surfaces to prevent the reformation of the natural oxide film.
