Abstract: A hub dynamo is compacted into a small diameter size while ensuring the generation of a high voltage of electric power. A coil chamber formed between a pair of main iron 10 cores, is partitioned in the axial direction by at least one sub iron 11 core to form a plurality of coil chambers. On the coil chambers a coil wire is wound such that the winding direction changes alternately between adjacent coil chambers. Magnetic flux collectors are connected to the outer circumference of the main/sub iron cores and include a plurality of first magnetic flux 15 collectors connected with the odd numbered iron cores and a (counting from either end) and a plurality of second magnetic flux collectors connected with the even numbered iron cores cores.

Abstract: A motor assembling apparatus is adapted to magnetize permanent magnets for the field and mount a stator 2 and an armature 3 in the same apparatus. The apparatus comprises a magnetizing unit 24 having an outer magnetizing coil 29 and an inner magnetizing coil 30, a vertically movable stator support 23 for supporting the lower end of the stator 2, an armature holder 25 to the outside of which the stator support 23 can be fitted and a stator keeping jig 22 arranged above the stator support 23. The stator 2 is placed on the stator support 23 and pinched between the stator keeping jig 22 and the stator support 23 to move it vertically and magnetize it by means of the magnetizing unit 24. After magnetizing the permanent magnets, the stator 2 is raised immediately by means of the stator support 23 and fitted to the armature 3.

Abstract: Apparatus and methods are disclosed for performing charged-particle-beam (CPB) microlithography in which aberrations arising from increased magnitudes of beam deflection are suppressed by making respective corrections for stage-position control errors. A CPB microlithography apparatus includes an image-positioning deflector that imparts a magnitude of deflection to the patterned beam appropriate for correcting stage-position-control errors. The magnitudes of correction are recorded in a memory of a statistical computer for each subfield of the pattern. Upon performing an exposure of a specified range (e.g., stripe) of the pattern containing multiple subfields, the correction values are statistically processed and trends (e.g., shifts in a specific direction) are analyzed.

Abstract: An electric motor, used for moving a seat of a vehicular seat apparatus, is mounted to mounting brackets so as not to produce vibration or unusual sounds. A cylindrical stepped portion projects from a bottom surface of a yoke of the electric motor. A fitting recess, formed in a frame member, is press-fitted over the yoke stepped portion such that the second frame member is checked from rotating relative to a motor armature shaft, but is allowed to move axially. The electric motor, including the second frame member, is disposed between a pair of first and second mounting brackets arranged in an opposed relationship in the axial direction of the electric motor. The electric motor is fixed by tightening screws into threaded holes formed in the frame member from an outer surface of the adjacent mounting bracket so that no gap is left between the frame member and the adjacent mounting bracket.

Abstract: A dc motor including a first set of pigtails passing out of the motor case through a grommet which is fitted in an opening formed in the motor case. This motor has a pigtail holder which fixes the first set of pigtails to the grommet. The pigtail holder includes first and second portions. The first portion is stationarily engaged with the grommet, while the second portion is fixedly connected to those portions of the first set of pigtails inside the motor case. With this fixed pigtail arrangement, movement of the first set of pigtails is restrained, and therefore, effects of vibration on the first set of pigtails are reduced when the motor is subjected to vibration.

Abstract: A construction of a starter motor for taking off the power to the outside, is operable wherein the power from the starter motor can be taken off as the externally operating section other than the power of an engine. The starter motor includes a first reduction mechanism having a motor shaft as an input shaft. The motor shaft transmits power to a coaxial output shaft. A pinion gear is provided on the engine side of the first output shaft in association with a ring gear. A second reduction mechanism utilizes the first output shaft as an input shaft, to transmit power to a second output shaft. The second output shaft is rotatably coupled onto the first output shaft and coaxial therwith, to permit the power to be taken off to the outside near the pinion gear. The first and second reduction mechanisms each include a sun gear provided on the input shaft, an internal gear and a plurality of planetary gears provided between the sun gear and the internal gear and being mesh with the both gears.

Abstract: The starter motor includes a first output shaft with a pinion gear in mesh with a ring gear of an engine. A first reduction mechanism outputs power from a motor shaft through the first output shaft. A second output shaft and a second reduction mechanism output power from the first output shaft through the second output shaft. The second output shaft is rotatably coupled onto the first output shaft and made coaxial therewith. Power can be taken out on the side of the pinion gear. Both output shafts are associated with each other through a stop member for regulating relative displacement in the axial directions, so that thrusts in directions opposite to the above directions different from each other, which have not been borne, can be borne by each of the output shafts on the other side, respectively.

Abstract: A magnetic head for recording and reading out of a magnetic recording medium in a perpendicular magnetic recording system is described in which the surface which is close to or in contact with the recording medium are covered with a film of a glasslike carbon material. This film improves the lubrication properties with respect to the adjacent recording medium and serves to prevent abrasion.
