Abstract: A coil spring for use in a link-motion-type suspension includes a lower end turn portion, an upper end turn portion, and an effective portion of a cylindrical shape between the lower end turn portion and the upper end turn portion. Further, the coil spring includes a bowing control portion including a taper portion formed in at least one end turn portion of the lower end turn portion and the upper end turn portion. The taper portion has a shape whose thickness is reduced from the middle of the end turn portion toward a distal end of a wire along its length, and bowing of the effective portion is suppressed by absorbing a change in the inclination of a spring seat by the taper portion.

Abstract: A fuel-cell-stack manufacturing method, includes arranging an extension portion extended from a proximal end of a raised piece on one surface of a base material disposed so as to abut at least one of a cathode side separator and the anode side separator, and setting an interval between the anode side separator and the cathode side separator along a lamination direction so that deformation of the raised piece exceeds an elastic deformation region and enters a plastic deformation region, and is also in a region in which the proximal end moved due to the deformation does not come in contact with the cathode side separator or the anode side separator.

Abstract: A head suspension includes a base to be attached to a carriage, a load beam having a rigid part and a resilient part that connects the rigid part to the base, the load beam applying load onto a read/write head, a flexure attached to the load beam and supporting the head, an actuator attaching part located between the base and the head, and a piezoelectric element being deformable in response to a voltage applied thereto to move the head in a sway direction relative to the base. For the head suspension, it bonds the piezoelectric element with a bonding tape to the actuator attaching part and applies an adhesive to fix the piezoelectric element to the actuator attaching part.
