摘要:
An optical disk drive includes a turntable, a first motor for turntable drive, an optical pickup and a drive mechanism arranged on a drive base and a separate traverse base that floats on the drive base. A loading drive mechanism drives a disk loading mechanism. A second motor can be driven in forward and reverse directions to supply drive power to the loading drive mechanism and a pickup drive mechanism. A drive power transfer path switching mechanism is used to switch the path through which drive power from the second motor is transferred to supply power to the loading drive mechanism and pickup drive mechanism. By continuously driving the second motor in one direction, then moving the optical pickup, raising or lowering the turntable, and transporting a disk can be accomplished in this sequence substantially continuously. By reversing the direction of motor drive, these operations can be accomplished substantially continuously in reverse direction in reverse sequence.

An optical disk drive which reduces the number of motors used for drive operation is thereby simplified while shock resistance, vibration resistance, and productivity are improved. A turntable, a first motor for turntable drive, an optical pickup and drive mechanism, are provided on a drive base and a separate traverse base that floats on the drive base. A loading drive mechanism drives a disk loading mechanism. A second motor can be driven in forward and reverse to supply drive power to the loading drive mechanism and a pickup drive mechanism. A drive power transfer path switching mechanism is used to switch the path through which drive power from the second motor is transferred to supply power to the loading drive mechanism and pickup drive mechanism. By continuously driving the second motor in one direction, moving the optical pickup, raising or lowering the turntable, and transporting a disk can be accomplished in this sequence substantially continuously; by reversing the direction of motor drive, these operations can be accomplished substantially continuously in reverse direction in reverse sequence.

An optical disc device, having a traverse base includes an optical pickup and a feed motor that drives the optical pickup forward and backward from an inner circumferential position of an optical disc to an outer circumferential position thereof. This device comprises a loading device for transferring an optical disc from the exterior of the device body onto the traverse base, and a loading driving device for driving the loading device by using the driving of the feed motor. The feed motor can move the optical pickup for signal reproduction and eject the optical disc to the exterior of the device, thereby reducing the number of motors used in the device to provide a more inexpensive optical disc device.

An optical pickup device featuring reduced number of components and improved workability for achieving cost reduction and improved product quality. A base stand (4) is provided with a first guide section (8) and a second guide section (9) which stand upright from the base stand individually and can slidably engage with the first and second engagement portions (11, 12) provided on a mount base (3), respectively. This arrangement permits the base stand (4) having the guide sections (8,9) fixed thereon to be assembled directrly with the mount base (3) including an optical pickup thereon, resulting in simplified assembly operation and enhanced operation efficiency. Further, integral forming of the base stand (4) together with the first guide section (8) and the second guide section (9) into one body enables it to reduce the number of components, cut the production costs and improve the product quality
摘要:
An optical disc drive apparatus including a main tray having a stack of subtrays mounted thereon and movable between withdrawn and inserted positions. When the main tray is moved to the inserted position, the subtrays stacked thereon are held at a stand-by position and a selected one of the subtrays is ready to be drawn towards a loaded position so that an optical disc resting on the selected one of the subtrays can be clamped in position and optically read out. When an optical disc resting on one of the subtrays other than the uppermost subtray then held at the loaded position is desired to be removed or replaced, not only can such one of the subtray be returned from the loaded position to the stand-by position, the main tray is allowed to withdraw from the inserted position back to the withdrawn position carrying such one of the subtrays and the subtray or subtrays positioned immediately thereabove while leaving the subtray or the subtrays positioned above such one of the subtrays at the stand-by position, so that such one of the subtrays can readily be exposed to the outside for removal or replacement of the optical disc resting thereon.
摘要:
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).
摘要:
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.
