Abstract: A heat dissipating fan for an induction motor comprises a motor shaft with a circular groove and an end part. A fan has blades and a hollow central shaft with a hole, and tennons are provided on an inner wall of the hole for fitting with the circular groove. A protection cover has an opening being passed through by the motor shaft. Furthermore, heat releasing fins are provided on the protection cover and space apart with each other surrounding the opening. The fan is characterized by that the blades is attached to the fan and is fixed to an annular base plate. The base plate has a slanted curvy surface structure.

Abstract: A device for adjusting tautness of a belt of a motor of a table saw is provided with an adjustment screw, and a pivot. In response to unfastening the adjustment screw, the motor counterclockwise rotates about the pivot to tighten the belt until predetermined tautness is obtained. The adjustment screw fastens to keep the belt at the predetermined tautness. Alternatively, the motor clockwise rotates about the pivot to loosen the belt.

Abstract: A table saw includes a table, a saw, a track, a slide strip, and a fence member. The table has an axial direction and a radial direction which are orthogonal to each other. The saw is arranged at a predetermined position of the table. The track is arranged at each side of the table. The slide strip is slidably engaged with the track. An outer surface of the slide strip opposite to the track has a first position part, a second position part, and a third position part. The first position part and the second position part are respectively arranged at two ends of the slide strip and the third position part is arranged at a center of the slide strip. The fence member is bridged on the table and secured to one of the first position part, the second position part, and the third position part.
