摘要： A needle roller bearing comprises a plurality of needle rollers and a retainer. The retainer includes a pair of annular parts and pillar parts connecting the pair of annular parts so as to form pockets in which the needle rollers are housed. A sidewall surface of the pillar part has a sheared surface punched by a punching blade so that the pockets are formed, and a fractured surface fractured by a material pressed by the punching blade. The needle roller is guided by the sheared surface.

The range “L2” is a range such that L2≧0.8×L when a roller length is “L”. When the dimension from the corner P of the flange on the inner diameter side to the starting point of the range “L2” is “L1”, the dimension “L1” is ranged such that 0.8 mm≦L1≦2 mm. In this range, the straightness of the track surface of the outer ring in the axial direction is not more than 0.008 mm and the parallelism thereof is not more than 0.015 mm.

摘要： A rotary unit with a built-in clutch which is short in its axial length. The rotary unit has an inner member having an outer periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the raceway groove, and a cylindrical outer member having an inner periphery formed with a raceway groove and a pair of cylindrical surfaces on both sides of the groove. A retainer mounted between the inner and outer members has a plurality of circumferentially spaced pockets each housing a rolling member and sprag housing recesses provided alternately with the pockets. In each recess is received a sprag having both ends thereof resting on the opposing cylindrical surfaces and biased by a resilient member so that its inner and outer arcuate surfaces contact the cylindrical surfaces. By arranging the sprags and the rolling members alternately with each other in the circumferential direction, it is possible to reduce the entire axial length of the rotary unit.

摘要： A torque limiter having an outer ring with a plurality of cam surfaces and spring supporting surfaces formed on an inner peripheral surface, an inner member mounted in the outer ring, and a plurality of rollers mounted between the cam surfaces and the inner member. Springs supported on the spring supporting surfaces bias the rollers in a direction to bite into the cam surfaces and the inner member. The springs have a predetermined spring force which is sufficient to maintain the rollers in wedging engagement between the cam surfaces and the inner member when a turning torque for turning the inner member in a direction to urge the rollers out of the wedging engagement is applied to the inner member, but only until the applied torque reaches a predetermined value.

摘要： An ink jet head used for pulsed droplet ink jet printer uses a grooved piezo-electric element. The piezo-electric element includes a plurality of grooves, diaphrams and actuators. The actuator and two grooves at both sides of the actuator, filled with stuffing material, covers a corresponding one of passages. Therefore, even if the stuffing material moves when the actuator is energized, an interference problem does not occur. Consequently, the flexure force of each actuator can transmit to the corresponding passage to jet ink in the passage via a nozzle.
