Abstract: If opening and deleting of arbitrary optical pathways are repeated in a configuration where plural OADM nodes are connected to each other in a ring manner, empty waves in the ring are fragmented, and thus, it is necessary to optimize the optical pathways. When an optical pathway is opened from an OADM node to a different OADM node, transponders capable of connecting two routes to the OADM nodes and of setting different wavelengths for two routes are mounted in a state where there are no empty waves on a part of the route, so that an already-opened optical pathway is detoured to a detour route or a different wavelength in the OADM ring, and continuous empty waves are produced in a section to be opened so as to open a new optical pathway.

Abstract: In an MPLS or GMPLS network, links for hops of a communication path and adaptation to be implemented on the border of management domains or layers are automatically appropriately selected based on a service type or a requirement for maintenance. First, a unit that appends an identifier of a service to be provided and an attribute of the service to a communication path establishment control message, and requests path establishment is installed in a source node. Secondly, a unit that determines a requirement for maintenance of the communication path and adaptation on the basis of the service identifier and/or service attribute is installed in each node. Thirdly, maintenance attributes of network resources are compared with the requirement for maintenance in order to determine links and nodes through which the communication path passes. The determined links, nodes, and adaptation are designated as action parameters for a switching unit and/or interface unit.

Abstract: In an MPLS/GMPLS network, a link used by a communication path for each hop and adaptations used at the boundary between management domains or layers are appropriately and automatically selected according to a service type and a required maintenance condition, without making a control sequence complicated. First, a unit for requesting path establishment by including an identifier of a service to be provided and a service attribute in a communication path establishment control message is provided for a source node. Second, a unit for determining a required maintenance condition for a communication path and adaptations according to the service identifier and/or the service attribute is provided for each node. Third, links and nodes through which the communication path passes are determined by comparing each of achievable maintenance conditions for network resources with the required maintenance condition.

Abstract: A pattern inspecting method and apparatus for inspecting a defect or defective candidate of patterns on a sample includes picking up an image of a sample by shifting a sampling position on the sample, measuring geometric distortion in an image of a standard sample, beforehand, and defining a size for which the measured geometric distortion is neglectable, obtaining a first image of the sample and a second image to be compared with the first image, dividing the first image and the second stage into images of a division unit having a size not greater than the defined size, comparing a divided image of the first image with a divided image of the second image, and for calculating a difference in gradation values between both of the divided images. The defect or the defect candidate of the sample is extracted in accordance with the difference in the gradation values.

Abstract: For purpose of providing a defect inspecting method and an apparatus thereof and a defect inspecting method on basis of electron beam image and an apparatus thereof, reducing possibility of bringing erroneous or false reports due to the test objection side and the inspecting apparatus side, being caused by discrepancies, such as the minute difference in pattern shapes, the difference in gradation values, the distortion or deformation of the patterns, the position shift, thereby enabling the detection of the defects or the defective candidates in more details, wherein an image which is small in distortion by controlling the electron beam scanning is detected and divided into a size so as to be able to neglect therefrom, and then position shift detection and defect decision are carried out in an accuracy less or finer than pixel for each division unit. In the defect decision, a desired tolerance can be set up depending upon changes in gradation values and the position shift.

Abstract: A compact antenna for circular polarization comprises a substrate of a dielectric material which is formed on its bottom surface with a ground plane and on its top surface with four planar rectangular patches of an electrically conductive material. The four patches are mounted in a coplanar relation on the top surface of the substrate, and arranged along four sides of a square pattern with the length of each patch angled at 90.degree. with respect to the length of the two adjacent patches. Each of the four patches is short-circuited to the ground plane at a shorting point located at a corner of the square pattern. A 90.degree. hybrid circuit is connected to directly feed only the two adjacent patches with a phase difference of 90.degree. to thereby define these two patches as active antenna elements which are fed with 0.degree. and 90.degree. signals, respectively.

Abstract: A method of preparing a film-forming polyphenylene oxide (PPO) composition as well as a laminate using such composition, wherein a setting means selected from the group consisting of a crosslinking monomer, a crosslinking polymer, and mixtures thereof, and, optionally, an initiator are added to and mixed with PPO, and a sufficient film-forming property is provided to PPO by allowing the setting means and, if present, the initiator to crosslink, whereby the PPO composition has the ability to form a film. Further, when a plurality of such films are stacked and integralized to form a metal-clad laminate, the laminate exhibits low dielectric constant and loss, so as to be used effectively in superhigh frequency bands such as the X band used for satellite communication.
