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: A computer system for managing log information, enabling correct comprehension of system logs for an identical resource before and after migration among plural nodes. A global ID, being unique in the system, is given to a resource (LU) migrated from one file share server to another. The global ID remains the same in the migration destination file share server after migration and log messages for the resource are obtained based on the global ID.

For a period till an actual stop of the internal combustion engine since a stopping condition of the internal combustion engine was established, an air quantity of air flowing into a cylinder of the internal combustion engine is decreased when a number of revolutions of the engine is higher than a specified number of revolutions (S102) and is increased when the number of revolutions of the engine is equal to or lower than the specified number of revolutions (S106).

Abstract: In the portable electronic device of the present invention, charging electrodes exposed to the exterior of a casing are electrically connected to a pair of charging terminals mounted upright on the printed circuit board, and a charging terminal (negative electrode, or ground) that is one of the pair of charging terminals is connected to the ground of the printed circuit board. A high-frequency current suppression part is mounted in a series connection on the charging terminal (negative electrode, or ground). The high-frequency current suppression part is a ferrite core, ferrite beads, or another low resistance part. In such a configuration, a secondary electric discharge occurs via the externally exposed charging electrodes and the like when electrostatic discharge noise is applied from the exterior of the portable electronic device and when the ground current of the printed circuit board oscillates due to the discharge electric current that flows at this time, whereby circuit malfunctions are prevented.

Abstract: At a time of stopping an internal combustion engine, inertia energy of the engine is kept constant, for example, by controlling a number of engine revolution constant, while controlling combustion of the engine. By utilizing the controlled inertia energy, the engine is stopped at a predetermined crank angle position. Since the engine is stopped at the predetermined crank angle position by utilizing the controlled inertia energy, a large amount of energy for controlling the stop position of the energy is not needed, and the energy needed for the stop control can be reduced. Since the inertia energy utilized for the stop control is always controlled in a predetermined state, the engine can be stopped at a proper position reliably each time.
