摘要： A stator includes a stator coil comprised of electric wires each of which has in-slot portions received in slots of a stator core and turn portions located outside the slots to connect the in-slot portions. Each of the turn portions is stepped to have parallel parts that extend substantially parallel to a corresponding axial end face of the stator core. For each pair of the turn portions of the electric wires, which respectively protrude out of an adjacent pair of the slots of the stator core, the parallel parts of one of the turn portions overlap those of the other in the axial direction of the stator core. A clearance provided between one of the overlapping pairs of the parallel parts, which is positioned furthest from the corresponding axial end face of the stator core, is largest among all clearances provided between the overlapping pairs of the parallel parts.

摘要： The larger the number of successive “0”s preceding a “1” in input data applied to a semiconductor laser, the longer the emission delay time of the laser. Accordingly, if a pulse signal for driving the semiconductor laser is made to rise earlier by an amount equivalent to the emission delay time conforming to the number of successive “0”s, thereby enlarging the pulse width, then the emission delay can be compensated for to eliminate pattern jitter irrespective of the number of successive “0”s. To accomplish this, a unit is provided for monitoring the number of successive “0”s in the input data, and a pulse-width adjustment circuit is provided for advancing the rise time of the laser driving pulse, thereby enlarging the pulse width, based upon the number of successive “0”s preceding a “1” in the input data.

摘要： An optical information reading apparatus such as a bar code reader includes a mirror drive unit rotatable to oscillate a movable scanning mirror simultaneously about a first axis and a second axis perpendicular to the first axis so that a laser beam irradiated from a laser unit is directed by the movable scanning mirror vertically and horizontally to scan parallel arranged plural rows bar codes with a raster scanning pattern. Since the raster scanning pattern can be formed by the combination of a single scanning mirror and a single mirror drive unit, the optical information reading apparatus is simple in construction and compact in size. In addition, the number of vertical scanning lines is not limited as opposed to a limited number of vertical scanning lines formed a polygon mirror incorporated in the conventional apparatus.

The stator core is comprised of a plurality of stator core segments that are arranged in the circumferential direction of the stator core to adjoin one another in the circumferential direction. The stator coil is mounted on the stator core. The outer cylinder is fitted on the radially outer surfaces of the stator core segments so as to fasten the stator core segments together. The restraint is arranged on an axial side of the stator core and retained by the outer cylinder so as to restrain axial deformation of the stator core segments due to the fastening force of the outer cylinder.
