摘要： A light source supplies optical signal to an optical switch and a detector detects light receiving level. A control unit changes a deflection control amount for changing an angle of a tilt mirror, and outputs the deflection control amount to a driving unit. When an input and an output ports are same, optical offset of the tilt mirror is calculated based on optimal angle at which the light detector detects an optimal point of the light receiving level. Whenever the input and the output port are different, a structure parameter of the tilt mirror is calculated based on the optical offset and the optimal angle. The optical offset and the structure parameter are stored in a memory as a test result.

摘要： An optical exchange for a wavelength division multiplexed (WDM) network performs a switching operation on a plurality of optical signals, which are input via a plurality of input ports, and outputs the resulting optical signals to a plurality of output ports, which are allocated to the input ports, by making deflection the optical signal; target amounts of the deflection to which the respective input optical signals are stored. The deflection is made using a switching controller, which reads out the target amount of deflection for such destination-of-switching output port with respect to such object-of-switching port, and controlling the deflection in such a manner that the individual input optical signals are deflected based on the respective target amounts of deflection. And during the switching, the power-level controller performs a feedback control for adjusting a power level of the individual deflected output optical signal to a target power level.

摘要： A method of manufacturing a stator coil for an electric rotating machine includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires through plastic deformation into a spiral or circular-arc shape; and (3) assembling the rolled electric wires together to form the stator coil. Further, in the rolling step, each of the planar electric wires is rolled by deforming each of the turn portions of the electric wire while restricting movement of at least one of the in-slot portions of the electric wire which is located closer to a rolling start end of the electric wire than the turn portion is.

摘要： A stator includes an annular stator core having a plurality of slots arranged in the circumferential direction at predetermined intervals and a stator coil formed of a plurality of electric conductor wires mounted on the stator core. Each of the electric conductor wires has a plurality of in-slot portions received in the slots of the stator core and a plurality of turn portions that connect, on the outside of the slots, adjacent pairs of the in-slot portions. The stator coil has first and second coil end parts and that respectively protrude axially outward from a pair of axial end faces of the stator core. At each of the coil end parts, the turn portions of the electric conductor wires are stacked in a radial direction of the stator core, and the axial heights h1 of the turn portions are set so as to gradually increase from the radially inside to the radially outside.
