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.

摘要： A stator for an electric rotating machine is provided which is equipped with a stator coil. The stator coil has a plurality of in-slot portions arrayed within each of slots formed in a stator core in a radial direction of the stator core. Adjacent two of the in-slot portions disposed in each of the slots have radially-facing surfaces which extend in non-parallel to one another at least one of ends of the in-slot portions. The non-parallel orientation of the radially-facing surfaces avoids close contact between entire areas thereof when the in-slot portions move undesirably within the slot in the radial direction of the stator core. In other words, a gap is kept between the radially-facing surfaces and serves as a radiator to dissipate heat, as generated in the in-slot portions.

摘要： A method of manufacturing a stator 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 by more than one turn into a spiral shape; (3) forming a stator coil by assembling the rolled electric wires through elastic deformation thereof; and (4) assembling the stator core and the stator coil to form the stator. Further, in the rolling step, each of the planar electric wires is rolled by plastically deforming the turn portions into circumferentially-extending sections each having a predetermined curvature. Furthermore, a curvature ratio of a radially-outermost one of the circumferentially-extending sections is set to be greater than that of a radially-innermost one of the same.
