A plurality of press devicesare arranged in a plastic working system. The plastic working system includes: a loop correction sensorfor watching a slack of a coil material C intermittently delivered from a preceding first press device; and a second slack watching meansfor watching a slack of the coil material C generated at the time of sending the coil material C to a succeeding second press device. According to the slack generated by intermittent feeding of the coil material C sent from the first press device, intermittent feeding is converted to continuous feeding by the feeding means. At the same time, the continuous feeding speed is subjected to speed increasing/decreasing control. On the other hand, by the second slack watching means, a slack of the coil material C is watched at the time of feeding the coil material C to the second press deviceand the preceding first press deviceis subjected to speed increasing/decreasing control.

A U-turn bus bar comprises a body portion constituting a linear essential part formed of a conductive plate member, having an overall thickness (t) and an overall width (); at least a terminal portion expanded in the direction perpendicular to the longitudinal direction of the body portion; and a connection hole formed at one end of the body portion. The body portion includes a U-turn bend formed by bending the body portion into a U-turn shape.

The present invention provides a propeller fan having a blade trailing edge of a sawtooth shape, in which the flows on the negative pressure side and the pressure side of a blade join gradually, so that the velocity loss is decreased in the vicinity of the trailing edge. As a result, the velocity gradient decreases and the generation of turbulence is reduced as compared with the conventional propeller fan, so that the noise is reduced and the fan efficiency is enhanced.

A zone-forming apparatus adapted to direct a jet-stream in a radial direction by a guide member, the jet-stream being emitted from jet-stream generator which is arranged above the apparatus, and an air curtain thus formed is utilized to define a working space.

A fluid suction nozzle and a fluid-treating apparatus are used in the cleaning of air inside a local space. The suction nozzle has a suction passage and plural annular discharge passages surrounding the suction passage. The nozzle is connected with an air cleaner, etc. The air inside a local space is to be drawn in through the suction passage. At the same time, a larger amount of air is to be discharged from the discharge passages. The velocity at which fluid will flow from the outer discharge passage is smaller than that at which fluid from the same source will flow from the inner discharge passage.
