摘要： Embodiments of the present invention prevent a magnetic disk drive from increasing in size and in manufacturing cost and reduces a positioning error of a magnetic head. An embodiment of a magnetic disk drive in accordance with the present invention includes: a disk-shaped magnetic disk that is rotated and driven; a magnetic head that reads and writes information to and from the magnetic disk, an arm that supports and moves the magnetic head; a spoiler that is close to a disk surface and extends in a radial direction of the disk; and a cabinet that houses these parts. The spoiler is disposed closer to an upstream side in a rotational direction of the disk than the arm and has a flow rate suppressing clearance positioned in a central portion in a peripheral direction of the spoiler, opened to both sides in an axial direction, and formed in a shape elongated in a radial direction of the disk.

摘要： Embodiments of the invention reduce disk fluttering while ensuring good assemblability in a magnetic disk apparatus. A magnetic disk apparatus comprises a recording disk that is an information medium configured by one or plural disks; a motor causing the recording disk to rotate; a carriage supporting a head that records information to, or plays back information from, the recording disk; a casing housing the recording disk; and a shroud disposed surrounding an outer periphery of the recording disk. A groove that extends along the recording disk is formed, vertically asymmetrical with respect to an outer peripheral surface of the recording disk, in the shroud surface at a position where a corner portion formed by the outer peripheral surface and a top surface or bottom surface of the recording disk extends in a radial direction.

摘要： A wafer is exposed to a plasma. Here, the wafer includes a semiconductor or a conductor 1 provided on an insulator 6, an insulator 2 formed thereon and having a region the thickness of which has been made locally thin, and a 2nd conductor 4 provided on the insulator 2, one of the semiconductor or the conductor 1 and the 2nd conductor 4 having a 1st region from the surface of which a substantially total solid angle is formed, the other having a 2nd region a solid angle formed from the surface of which is made smaller than the 1st region. Then, a voltage is applied to the semiconductor or the conductor 1 and the 2nd conductor 4 so as to measure a time elapsing until the insulator 2 undergoes a dielectric breakdown. Moreover, the ion current density is determined from an electric charge required therefor and an area exposed onto the surface of the 2nd conductor 4. Consequently, it becomes possible to measure, on the wafer, the current density of the ions launched into the wafer, thereby allowing the measuring method of the icon current density to be made suitable for the mass production.

摘要： A scroll-type fluid apparatus including an orbiting scroll member, a stationary scroll member, and a plurality of pockets formed in at least one of the orbiting scroll member and the stationary scroll member to cooperate with the other scroll member for confining liquid therein. When an axially urging force is ecerted on the orbiting scroll member, a liquid pressure commensurate with the axially urging force is produced in the pockets, so that such liquid pressure cancels out a biased axially urging force (moment) exerted on the orbiting scroll member.
