Abstract: In an individual-spindle-drive type multiple twister that directly employs separate motors to drive the spindle shafts of each twisting unit, when a spindle is inserted into the housing during motor assembly, a rotor and a stator may attract each other and adhere to each other, and this attraction may prevent the spindle shaft from being correctly inserted into a target bearing, thus making it difficult to assemble the motor. A spindle shaft 4 is rotatably supported by bearings 27a and 28a mounted onto upper and lower supporting members 27 and 28. The distance A between the lower end of the rotor magnet 32 of the drive motor 10 fixed to the spindle shaft 4 and the lower end of the spindle shaft 4 is longer than the distance B between the upper end of the stator coil 31, which is fixed to the housing 34 of the drive motor 10, and the bearing 28a of the lower supporting member 28. In addition, the tip 4 of the spindle shaft 4c is tapered to facilitate insertion.

Abstract: A pneumatic tire for a heavy load is provided which prevents irregular abrasion generated at the edge of land portions of the tire tread. An irregular abrasion preventing land portion is thus formed at the edge of a land portion, inside the shoulder edge of the tire, whereby the irregular abrasion generated at this portion is prevented.

Abstract: A liquid jet recording method for recording on a recording material with liquid droplets discharged through plural scanning nozzles arranged in a width measured in a direction of main scan. The recording method includes a first main scan by relative movement between the nozzles and the recording material, in which pixels are recorded with numbers of droplets through a nozzle, the numbers of droplets corresponding to respective tone signals. The method also includes a sub-scan by relative movement between the nozzles and the recording material in a direction crossing with a movement direction of the first main scan. The method further includes a second main scan in which the pixels are recorded with numbers of droplets through a different nozzle, the latter numbers of droplets corresponding to tone level signals. The sub-scan and second main scan steps are repeated to record a tone image by discharging plural droplets for a pixel.

Abstract: An ultrasonic medical apparatus, particularly convenient for use inside a body cavity, includes an applicator having an ultrasonic transducer, which may be attached to an acoustic lens such that the emitted ultrasonic waves are focused at two or more different positions. For this purpose, the wave-emitting surface of the transducer, or the acoustic lens attached to it, is partitioned into concave surface elements which may be in a concentric annular arrangement and may each have a different radius of curvature and a different center of concavity. An apparatus thus structured can be made compact and hence is convenient for use inside a body cavity.

Abstract: After an ink-jet recording head with a plurality of discharging portions arranged is main-scanned in a direction perpendicular to the direction of the discharging portion arrangement to record a first image area, sub-scanning of the head is performed. Before the head is main-scanned to record a second image area, the sub-scanning is performed so that a few discharging portions on an upper edge portion of the head in second main-scanning overlap part of the first image area. Ink droplets land on pixels in the overlapping portion twice for each main-scanning, and image density of the pixels in the overlapping portion is controlled by the sum number of the landing ink droplets. This enables image density unevenness of image density, example, a "black stripe (banding)" or a "white stripe (banding)" in a boundary of an image area being recorded in each main-scanning, to be markedly reduced.
