摘要:
An optical ring system having: a wavelength demultiplexer to which wavelength-multiplexed optical signal to be sent through an optical fiber from a previous node of multiple nodes is input and in which optical signal with each wavelength assigned to itself is demultiplexed; an optical ring device which is disposed in a predetermined node of the multiple nodes to the each wavelength assigned and which is composed of a failure existence judging part which terminates an overhead of each optical signal with a wavelength demultiplexed by the wavelength demultiplexer and judges whether a failure occurs in regard to a wavelength in a previous section through which optical signal with the assigned wavelength is sent, and a switching part which, when the failure existence judging means determines the occurrence of failure, selects a path that allows optical signal with the wavelength to be transmitted to the previous node while avoiding the previous section incurring the failure; and a wavelength multiplexer which multiplexes optical signal to be output from the optical ring part and then outputs it to an optical fiber connected to a next node.

Disclosed is a WDM network which has: a lightwave path which connects between clients and each of which is provided with an overhead, and a sub-network which is defined by dividing the WDM network. In this WDM network, the sub-network has a partial lightwave path to go through the sub-network, the overhead has a partial lightwave path supervisory control information region which is terminated at both nodes of the partial lightwave path, and when a fault occurs on a lightwave path, the fault information of partial lightwave path including the position information of fault occurred is added to the partial lightwave path supervisory control information region of the overhead.

There is provided a substrate processing method, in which a throughput can be improved even in case the time for recovery processing for restoring the state of a processing chamber is longer than the time for predetermined processing to be performed in the processing chamber. Substrates are alternately transferred to two processing chambers C, D, and the same film forming processing is performed on the substrates in the processing chambers C, D in parallel with each other. When the number of substrates processed in the processing chamber C has reached a predetermined number (11 substrates), dummy sputtering processing in the film forming chamber C is started and also 23rd-25th substrates of the first lot are transferred to the film forming chamber D to thereby perform film forming processing until the dummy sputtering processing is finished.

In automatic programming for creating a multi-path program for a machine having a plurality of control paths performing one or more machining processes of a machining program for machining a workpiece, the machining time of each of the machining processes is calculated, workable paths are input for each of the machining processes, and then workable orders of the machining processes are input. For each of the machining processes, simultaneously workable machining processes are input if any among other machining processes. On the basis of the above results, machining programs that provide the shortest machining time are selected.

The present invention relates to a curing accelerating compound-silica composite material capable of giving excellent storage stability to a curable resin composition, which is obtained by subjecting one or more compounds selected from compounds represented by the general formula (I-1) below and partial condensates thereof to a sol-gel reaction in the presence of a curing accelerating compound and water; a curable resin composition comprising the same; and an electronic component device comprising a device sealed with the curable resin composition. R1nSiR2(4-n) (I-1) wherein n is 0 or 1; R1 is selected from a hydrogen atom and a C1 to C18 substituted or unsubstituted hydrocarbon group and may form a ring structure with R2; R2s represent a functional group reactive with a phenolic hydroxyl group, are selected independently from a halogen atom, a hydroxyl group, a C1 to C18 optionally substituted oxy group, a C0 to C18 optionally substituted amino group, and a C2 to C18 optionally substituted carbonyloxy group, all R2s may be the same or different from one another, and two or more R2s may be bound to each other to form a ring structure.

There is provided a robot hand for substrate transfer in which the robot hand is so arranged that, even in case a substrate (S) gives rise to warping, the substrate (S) can be stably supported. On an upper surface of the robot hand there is formed a first seating surface on which is seated a lower-surface peripheral portion of the substrate (S) and, on a periphery thereof, there is formed an upwardly extended step. The step is provided with a plurality of stair-shaped stages. On an upper surface of the robot hand inwardly away from the first seating surface there is provided a second seating surface which is inclined downward toward the center of the substrate (S) such that a lower surface of the substrate (S) is seated on the second seating surface when the substrate (S) is warped downward into a concave shape.

There is provided a running device for track-laying vehicle, which can resolve a feeling of fear of falling height in a leading end portion of a crawler while relax a large impact when the crawler runs over a raised contact area. The running device includes a spring constant equalizing unit that equalizes an apparent spring constant of a second arm of lower track roller bogie device over a total length. The apparent spring constant is generated in maximum reverse camber of the crawler. The spring constant equalizing unit increases an oscillation angle α of the second arm that can abut on the first arm in the maximum reverse camber of the crawler such that the oscillation angle α of the second arm is larger than a crossing angle β of the connecting link. Desirably the increased maximum oscillation angle of the second arm is 1.3-2.0 times the crossing angle β.

A numerical controller in which similar icons are created without applying major load onto a memory. Among icon definition data displayed in areas F1 . . . , G1 . . . , H1 . . . , on frames A, B and C, the data that can be expressed by conversions, such as rotation, horizontal mirror image, vertical mirror image, horizontal-and-vertical mirror image, magnification/contraction retaining horizontal/vertical ratio, magnification/contraction varying horizontal/vertical ratio, black/white reversal, display in red, blue, yellow and green, with respect to one parent icon, are substituted with data indicating the conversion contents. It is possible to display many icons with a small storage capacity. The definition data of each icon can be previously written in a ROM and copied to a RAM when the power is turned on to be used for display.

The method of manufacturing a bonded wafer including, implanting hydrogen ions, rare gas ions, or a mixture of hydrogen ions and rare gas ions into a bond wafer to form an ion implantation layer in the bond wafer, bonding the bond wafer in which the ion implantation layer has been formed to a base wafer to form a bonded wafer, and subjecting the bonded wafer to heat treatment to separate the bond wafer from the base wafer at the ion implantation layer as boundary to form the bonded wafer. In the method of manufacturing a bonded wafer, the heat treatment at least from the start of the separation to the end of the separation is conducted in an oxidizing atmosphere.

An improved scroll compressor comprises a fixed scroll and an orbiting scroll, as well as an Oldham's coupling which enables the orbiting scroll to have a orbital movement. The Oldham's ring of the Oldham's coupling is so formed that its sliding surfaces for counterpart members to slide thereon are formed by a base material containing silicon particles, while the surface of each silicon particle (remaining on the base material's surface serving as a slidable surface for counterpart members to slide thereon) is formed into a flat surface. In practice, a ratio of silicon portions formed into flat surfaces to an entire sliding area of the Oldham's coupling is in a range of 3% to 20%, preferably 5% to 15%. With the use of the scroll compressor of the present invention, it is possible to improve the wear resistance of the Oldham's ring of the Oldham's coupling and its counterpart members in the scroll compressor.
