Abstract: A magnetic disk drive apparatus has a spindle holding mechanism for a spindle that supports a plurality of magnetic disks. The spindle is rotatably supported on a base by two bearings. Each bearing is pressed by a compressive coil spring to the base in the direction parallel with the plane of the magnetic disks and perpendicular to the axial direction of the spindle. Additionally, one of the bearings is affected with a pressing force in the axial direction of the spindle by another compressive coil spring. Therefore, even if the bearings have a thermal expansion coefficient different from that of the base, the thermal expansion can be absorbed by the compressive coil springs thereby preventing a generation of thermal stress between the parts. Consequently, deflection in relative position between the two bearings is prevented, and an inclination of the spindle is avoided.

Abstract: A brake apparatus for automatic doors including a speed pulse signal output device for providing speed pulse signals at a time interval inversely proportional to the door speed of an automatic door, a brake for slowing the door speed, a braking position detector for detecting braking position when the brake starts braking, a brake effect measurer for measuring the effect of the brake and a braking power controller for adjusting the braking power of the brake in accordance with the measured braking effect whereby the motion of the door is kept constant irrespective of the door weight and other conditions.

Abstract: A spindle assembly for magnetic disks of both-end support type has a hub for fixing the disks, a shaft to which the hub is fixed, a pair of bearings which are spaced in vertical or horizontal direction, a pre-loading spring for pre-loading one of the bearings, and a housing composed of housing parts which accommodates the hub, shaft, bearings and the pre-loading spring. The spindle assembly further has an axial reference surface formed on the hub at a right angle with respect to the shaft, and another axial reference surface formed on one of the housing parts at a right angle with respect to the vertical portion of the bearing associated with the one of the housing parts. When the shaft is mounted in the one of the housing parts with the hub and the pre-loading spring fitted therearound, the hub is axially urged by the spring such that the axial reference surface thereon is brought into abutment with the axial reference surface on the one of the housing parts.
