Abstract: Powder-particle material in compression molding is transferred using air suction power and filled thinly, evenly and rapidly in a female mold. An adsorption pad 21 which is held so as to be freely movable in the vertical direction is provided at a movable cylinder 7, which can move in the horizontal direction in a space between a metal supply hopper 2 and a female mold 34 and rotate 180°, and powder particle material is laid in a scraped manner at the adsorption pad 21, adsorbed by actuating a vacuum pump 14, transferred to the female mold 34 in this state, turned around and caused to fall into the mold by terminating adsorption.

Abstract: In a magnetic disk unit for recording/reproducing data onto/from a disc by means of a magnetic head on the basis of a seek command and a recording/reproducing command received from a host processor, the execution of the data reproducing command for the disk is started upon detection of a state that the magnetic head has sought on a desired track to an extent that the centering state is still unstable but the data can be reproduced, and the execution of the data recording command is started upon detection of a condition that the magnetic head has reached the stable centering state on the desired track after the detection of the reproducible state.
