摘要： Disclosed in an optical switching connector provided with a first and second ferrule disposed with end faces thereof abutting on each other and two reference pins disposed in parallel at a predetermined interval. The first and second ferrules have two parallel pin holes, respectively. The two reference pins are inserted in the pin holes. The pin holes have an elongated sectional shape enabling the reference pins to move laterally by exactly a certain movement pitch. The first and second ferrules are able to be positioned at one position determined by one of the inside surfaces of the pin holes being pressed against the reference pins and another position determined by the other inside surfaces of the pin holes being pressed against the reference pins. One of the first and second ferrules has fixed in it two or more optical fibers at a pitch of 1/n (n being a positive integer) of the above-mentioned certain movement pitch, while the other ferrule has fixed in it one or more optical fibers so to correspond with all or part of the same.

The stator windings are consecutively divided into i subgroups in a circumferential direction, each subgroup having N stator windings. The electric machine further comprises i current control modules and i temperature measurement devices, each current control module being correspondingly electrically connected to the N stator windings in one corresponding subgroup, so that when the stator windings in the i subgroups are supplied with power by the i current control modules, a rotating magnetic field is generated around the rotor. Each temperature measurement device is configured to measure the temperature of one corresponding subgroup in the i subgroups during operation of the electric machine.

摘要： An optical waveguide chip assembly in which a plurality of optical waveguide patterns and two positioning grooves are laterally arranged is prepared by forming a plurality of optical waveguide patterns and two positioning grooves on a wafer in parallel to each other and cutting the wafer. Separately from this, an optical fiber array assembly having a plurality of optical fiber array cables and two guide pin holes is prepared. The optical waveguide chip assembly and the optical fiber array assembly are joined while aligning by the guide pins and then divided into units of individual optical waveguide modules. A large number of optical waveguide modules can be made with a good efficiency, and the mass productivity is improved. Since a plurality of optical waveguide modules are made by the same positioning, variations among products can be reduced.

摘要： A torque variation in an internal combustion engine due to the combustion variations is detected at each predetermined period. An average torque variation to be compared with the detected torque variation is predetermined experimentally based on the engine speed and the intake manifold pressure and is stored in a memory. The number of the detected torque variations which exceed the average torque variation multiplied by a predetermined constant is counted, and if the ratio of the counted number to the total number of the detected torque variations is larger than a predetermined reference value, then the presence of a torque variation is determined.
