    摘要: A spirally corrugated pipe elbow according to the present invention is constructed in such a manner that after a bend forming portion of a pipe body P having a given length and including a spirally corrugated pipe wall 1, with a partial portion a of the pipe wall 1 existing in the peripheral direction of the pipe body P left uncut, is cut and removed from the pipe body P in the form of a cut portion having a substantially V-like shape when it is viewed from the side surface side thereof, the thus obtained two cut surfaces are then bent and contacted with each other with the uncut pipe wall portion a set on the large diameter side, and the thus contacted portions t are connected together in a watertight manner using connecting material m. Accordingly, it is possible to provide an elbow having a structure free from the above water leakage and a method capable of manufacturing such elbow easily and quickly.

    摘要: Embodiments of the invention correct the static attitude of a head gimbal assembly (HGA) with high accuracy. In one embodiment, a vector group that constitutes the shortest path from the initial attitude of the HGA to the final anticipatory attitude is formed. The vector group is formed of the plural displacement vectors that give a variety of variations in static attitude when unit shots of laser light are performed on the HGA. Displacement vectors are synthesized while the displacement vectors each giving the anticipatory attitude closest to a target attitude are being selected in order from the initial attitude, toward the target attitude. Unit shots equivalent to the number of displacement vectors are performed on irradiating positions related to the displacement vectors included in the vector group. The static attitude existing after the unit shots is measured, then the displacement vectors are corrected, and a vector group constituting the new shortest path is formed. Highly accurate attitude correction is thus realized.

    摘要: A method for removing a lead-free solder from a slider pad is provided to permit re-utilization of a head/slider used in a magnetic disk drive. In one embodiment, a slider pad formed on a head/slider and a lead pad are connected to each other through a lead-free solder fillet. A cutting tool is heated beforehand to a temperature near the melting point of the lead-free solder. The cutting tool is moved in parallel with a surface of the slider pad to cut the solder fillet while softening the solder fillet. The solder fillet is removed so as not to impose a stress on the slider pad and in a state in which the head/slider can be re-utilized.

    摘要: A set of bonding pads are ultrasonically connected to a set of leads. The bonding pads are formed on a predetermined plane of a slider held by a slider holder accessible to the recording plane of a disk in a disk drive. The leads are held by the slider holder and have joints that are formed so as to respectively face each of the bonding pads. A front end plane of a wedge working on the joints is tilted in a direction in which the first sides of the joints correspond to external connection sides. The ultrasonic connection is completed by pressing the joints of the leads against the faced boding pads.
