摘要:
A magnetic head suspension of the present invention includes a flexure having a magnetic head mounting region, a load beam connected to the flexure and having a dimple at a portion corresponding to the magnetic head mounting region a load-bent portion generating a load for pressing a magnetic head to a magnetic disk via the load beam, and a base portion connected to a rear region of the load-bent portion. The load beam has a reinforcing structure that is symmetrical as viewed from the above based on a center longitudinal axis line, only in a center region in a longitudinal direction from a rearmost portion at the rear region to the dimple.

摘要:
1A-Higher aliphatic acyl derivatives of mitomycin C have been found to have superior anti-tumor activity and lipid-solubility as compared with known 1a-acyl derivatives of mitomycin C. Also, the new derivatives exhibit far lower toxicity than mitomycin C. These derivatives are represented by the following formula: ##STR1## wherein R is an aliphatic hydrocarbon group having 9-29 carbon atoms or a group wherein a hydrogen atom of the aliphatic hydrocarbon group is substituted by a hydroxy group.

Provided that a distance between a distal edge of a supporting part and a dimple is represented by L1, a load beam part is bent around a first bending line within a center region away from the distal edge of the supporting part by more than or equal to 0.4*L1 and less than or equal to 0.6*L1 and also around a second bending line positioned closer to a proximal side in the suspension longitudinal direction than the first bending line. Paired leaf springs are bent around a third bending line. The second bending line is positioned within a proximal region within 0.22*L1 from the distal edge of the supporting part, and no paired flange portions exist at an area at which the second bending line is positioned.

The present invention provides a magnetic head suspension, wherein a supporting portion such as an arm or base plate includes a pair of supporting pieces extending from its opposite sides in the widthwise direction to a tip-end side of the suspension, and a concave portion which is defined by the pair of supporting pieces and is opened toward the tip-end side of the suspension, there is provided an elastically-deformable elastic plate which is connected to the pair of supporting pieces at a first end and a second end in the widthwise direction of the magnetic head suspension, the member forming the load beam portion is connected to the elastic plate, and the elastic plate forms the load bending portion.

It is an object to achieve prevention of lowering resonant frequency and improved production efficiency while achieving reduction in weight of a supporting part with a boss portion and reduction in thickness at area at which the boss portion is located. In the present invention, the supporting part includes a first supporting member with which a load bending part is connected, and a second supporting member with the boss portion and a main body region extended radially outward from the boss portion. At least one of the inner periphery of the mount hole and the outer periphery of the main body region is integrally provided with a rib region. The first and second supporting members are connected to each other by a restoring force of the rib region that has been elastically and/or plastically deformed by the other one of the inner periphery of the mount hole and the outer periphery of the main body region with the main body region being located at least partially in the mount hole in a through-thickness direction.
摘要:
An elastic plate connected at both ends to a pair of supporting pieces of a supporting portion and connected at center to a member forming a load beam portion functions as a load bending portion. A balance mass member is mounted on a portion of the member forming the load beam portion positioned on a base-end side from the elastic plate. A narrowest portion of the supporting portion is positioned, with respect to the suspension lengthwise direction, between a position of a base-end of a concave portion defined the pair of supporting pieces and a position where phantom lines extending from inner side edges of arm areas of the supporting pieces intersect with a longitudinal center line of the suspension, thereby effectively reducing mass of tip-end side of the supporting portion without deteriorating rigidity of the supporting pieces.
