摘要:
A magnetic disc drive apparatus in which a magnetic disc rotating section and a head arm having a magnetic head are accommodated within a casing and a main printed circuit board is attached to a bottom surface side of the casing is comprised of an auxiliary printed circuit board having at least a recording/playback amplifier, a playback side frequency characteristic circuit and a playback side pulse shaping circuit and which is accommodated within the casing, the auxiliary printed circuit board being connected to the magnetic head and the main printed circuit board. Thus, recording/reproducing signals can be prevented from being deteriorated by inside or extraneous noise and space for assembly parts on the main printed circuit board can be saved.

Disclosed is a proton conducting polymer membrane formed by laminating a plurality of solid electrolyte membranes. This proton conducting polymer membrane is one prepared by laminating at least one layer of a solid electrolyte membrane formed by using a resin having a bis(perfluoroalkanesulfonyl)methide group in the chemical structure. This solid electrolyte membrane has a superior proton conductivity without transmitting the fuel (methanol or hydrogen).

When migrating a virtual server between a plurality of physical servers, a pre-migration connection relationship between the virtual server and a storage area used by the virtual server is maintained after the migration of the virtual server by using a cooperative mechanism between a plurality of storage apparatuses even if the storage area used by the virtual server is migrated between the plurality of storage apparatuses. A computer system and virtual server migration control method for the computer system is described.

A semiconductor device includes: a semiconductor element that includes an electrode layer on a surface of the semiconductor element; a low-strength layer that is provided on a surface of the electrode layer; a bonding layer that is provided on a surface of the low-strength layer; and a conductive plate that is provided on a surface of the bonding layer. Strength of the bonding layer is higher than strength of the electrode layer, and strength of the low-strength layer is lower than the strength of the electrode layer.

A snapshot volume is migrated by using a primary volume of a migration destination storage apparatus.The management server comprises a controller for generational management, by means of the snapshot volumes, of differential data for the logical volume which is the parent volume of the snapshot volume, and, if an instruction to copy a snapshot volume of a designated generation is received and a snapshot volume prior to the designated generation of the copy instruction-target snapshot volume exists, the controller copies the differential data between the designated-generation snapshot volume and the existing snapshot volume, and associates the copied differential data with the existing snapshot volume.

A storage system capable of identifying all volumes to be audited is provided.Operation logs 3005 concerning the operations of volumes are associated with a time and stored in storage apparatuses 1400 and 1500, and a management computer 1100 collects information about these operation logs 3005, restores the status history of the operation logs 3005, sets, as an audit range, the operation logs 3005 including volumes with an audit period and audit target data stored therein, extracts the operation logs 3005 belonging to the audit range from the restored status history of the operation logs 3005, and transmits the extracted operation logs 3005 to a computer (requesting computer) 1000. As a result, all the audit target volumes can be identified.

A detachable cover for a motorcycle cowling that can be easily switched with a service part is described. The cover includes a cover front edge section that is formed so as to form a generally continuous surface with at least a portion of an outer periphery edge section of a head light, and a cover rear section that is removably attachable to the cowling and that extends to the rear from the cover front edge section when attached to the cowling. A motorcycle that easily allows external appearance to be changed to satisfy a user's requirements is also described.
