Abstract: PURPOSE:To easily and efficiently manufacture a homogeneous metal matrix composite at a low cost by adding a rapidly solidified alloy powder in which low-melting metal is finely and uniformly dispersed and a reinforcement to a semimolten slurry of matrix metal and then mixing the above. CONSTITUTION:A molten metal consisting of a matrix metal and a metal having a melting point lower than that of the above matrix metal is subjected to rapid solidification treatment. As the above low-melting metal, Sn, Pb, In, Bi, etc., are used, and, as the above matrix metal, Al alloy, Mg alloy, and Cu alloy are used. By the above treatment, a rapidly solidified alloy powder in which the above matrix metal is finely and uniformly dispersed is prepared. On the other hand, the above matrix metal is heated up to a temp. of its solidus temp. or above to undergo partial melting, by which a semimolten slurry is formed. Subsequently, the above rapidly solidified alloy powder and a reinforcement composed of ceramics are added to the above slurry, and these are mixed by agitation and formed into a composite material. As the above reinforcement, at least one kind among whiskers, fibers, and grains is used. By this method, the homogeneous metal matrix composite in which the low-melting metal having a lubricating function and the reinforcement increasing wear resistance are uniformly dispersed and which has superior characteristics of low friction and wear resistance can be obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent accuracy for detecting a peak value from being degraded by the effect of a residual magnetic pole by attaching a rotor magnet and an index magnet so that the boundary of the N and S poles of the rotor magnet is matched with that of the index magnet. SOLUTION: The rotor magnet 46 of a spindle motor is attached and fixed to a rotor yoke 44, then magnetized to form a pair of magnetic poles of the rotor magnet 46 and a FG magnet 45. Then, the index magnet 50 is attached to the side face of the rotor so that the boundary of its N and S poles are matched with that of the N and S poles of the rotor magnet 46. Thus, the phase of the N and S poles of the rotor magnet 46 is matched with that of the N and S poles of a residual magnetic pole 60 formed in the side face of the FG magnet 45, and the peak of the magnetic force line of the index magnet 50 is matched with that of the residual magnetic pole 60.  Thus, when the peak value of the magnetic force line of the index magnet 50 is detected by a Hall element 51, the accuracy for peak value detection is prevented from being degradaded by the effect of the magnetic force line of the rotor magnet 46.
