of one containing case 133 2 operation of sintered magnet production system 10 of present embodiment initially a container 21 is conveyed to a position below the hopper 111 of the filling section 11 by the conveyer 16 and the hopper 111 is attached to the upper side of the container 21 next compressed gas in a pulsed form is repeatedly supplied from the gas supplier 113 to the hopper 111 to make the alloy powder in the hopper 111 pass through the sieve member 112 and fill the cavity 211 of the container 21 subsequently the hopper 111 is removed from the container 21 and the container 21 is conveyed to the piling section 12 by the conveyer 16 these operations are cyclically performed for each container 21 until n containers 21 are completed in the piling section 12 initially one ferromagnetic member 132 is placed onto the first elevating stage 121 by the first top lift 122 next the first elevating stage 121 is lowered so that the top face of the containing case 133 of the ferromagnetic member 132 will be level with the conveyer line of the conveyer 16 then one container 21 conveyed from the filling section 11 by the conveyer 16 is placed onto the top face.
