A workpiece is unloaded from a wafer-receiving container. A first discriminating sensor detects a front surface of the workpiece, and determines either a semiconductor wafer or a spacer is the workpiece. Where the workpiece is a wafer, the first discriminating sensor also determines whether or not a protective tape is on the front surface of the workpiece. Where it is determined that a protective tape is not on the front surface, a second discriminating sensor detects a back surface of the wafer for discriminating the presence or absence of the protective tape.

A ring frame and a substrate are held on each table via an adhesive tape. An annular separation member presses the adhesive tape between the ring frame and the substrate, thereby separating the adhesive tape from the ring frame. After separation, the adhesive tape hung down is held by a holding member. Surfaces of the ring frame and the substrate are transferred onto a new adhesive tape while the adhesive tape is pressed by a joining roller. Then the separated adhesive tape is held by the holding member. The substrate joined to the new adhesive tape to be integrated with the frame is moved upward and horizontally. Thereby the separated adhesive tape is separated from the surface of the substrate.

A first virtual storage and a second virtual storage share an external LU (Logical Unit) inside an external storage. The first virtual storage comprises a first LU, which comprises multiple first virtual areas and conforms to thin provisioning, and an external capacity pool, which is a storage area based on the external LU, and which is partitioned into multiple external pages, which are sub-storage areas. The second virtual storage comprises a second LU, which comprises multiple second virtual areas and conforms to thin provisioning. In a data migration from the first LU to the second LU, for a data migration from a first virtual area, to which an external page has been allocated, to a second virtual area, the first virtual storage notifies the second virtual storage of a migration-source address, which is an address of the first virtual area, and an external address, which is an address of the external page that has been allocated to this virtual area, and the second virtual storage stores a corresponding relationship between the notified migration-source address and external address.

The present invention efficiently changes a volume size while maintaining a copy pair as-is. A PVOL and a SVOL #1 are in a pair state and are synchronized. The PVOL and a SVOL #2 are in a restore state. Upon instruction of expansion of the size of the PVOL, the size of a copy-destination SVOL #1 is first expanded, the size of the PVOL is then expanded, and the size of the SVOL #2 is lastly expanded. In the case of a PSUS state, only the size of the PVOL is expanded, and the size of the SVOL is left as-is.

An original master tape having a long carrier tape and a long double-faced adhesive tape joined thereto is guided to a knife edge to be folded back. The double-faced adhesive tape is half-cut on the carrier tape in front of the knife edge with a Thomson blade having a corresponding shape to a substrate. The original master tape is folded back at the knife edge. Accordingly, a piece of the double-faced adhesive tape cut into the substrate shape is separated from the carrier tape to be joined to the substrate traveling relatively at a speed synchronized to a separation speed.

The invention provides a method for computing the appropriate capacity of a journal volume based on the operating patterns of backup and recovery performed by the user, and composing a recovery system that enables recovery to be performed in a short time using journals. The invention provides a computer system comprising a storage system 120 having a volume 124, a managing computer 100 and a host computer 110, wherein the storage system 120 retains a journal of data stored in the volume and a volume replicating the data stored in the volume, and restoring a volume data at any update time point based on the journal and the replicated volume, and upon receiving operation from a user regarding the volume retaining the journal, the managing computer 100 acquires a registration creation demand including a recovery time objective which is the time to be restored and/or a recovery point objective which is the recovery time point and a journal retention period which is the period for retaining the journal, monitors the journal of data stored in the volume, computes the quantity of the journal, and determines the capacity of the volume for retaining the journal.

Tape heating means is allowed to come close to an adhesive tape for support and, in a heating state, the adhesive tape for support is stretched and tensioned with proper tension in a tape width direction and a transport direction. A heated work is bonded to an adhesive face of the tensioned adhesive tape for support, thereby supporting the work.

Conventionally, no consideration was given to the control of the main power supply circuit in a storage apparatus. Thus, unnecessary electric power will be consumed because it is not possible to inhibit the power consumption of the main power supply circuit of the storage apparatus. With this storage system having a plurality of storage apparatuses, a storage apparatus internally has a power supply control program for controlling the respective components and the main power supply circuit, and the power supply control command program provided to the management computer migrates a storage extent to be used for business to another storage apparatus based on the operation schedule of business to use the storage extent of the storage apparatus, and commands the power supply control of the main power supply circuit in the storage apparatuses and the respective components.

Provided is an improved method of joining a protective tape having one object to suppress generation of bending of a semiconductor wafer after a back-grinding process. The protective tape is supplied toward the semiconductor wafer suction-held on a chuck table, and an intermediate sheet is supplied along an upper side of the protective tape. Then, the intermediate sheet is interposed between a joining member and the protective tape along a surface of a base material in the protective tape so as to be movable. Under this state, the joining member and the semiconductor wafer move relative to each other in a horizontal direction, whereby the protective tape is joined to a surface of the semiconductor wafer.

Provided is an environment that storage device configuration management can be efficiently done in a data center having a virtualization device. A SAN manager acquires configuration information from a device constituting a SAN and prepares a correspondence relationship between a host computer and a virtual volume in the SAN, and a corresponding relationship between the host computer and a real volume, depending upon the acquired information. Based on the corresponding relationship, the SAN manager outputs a correspondence relationship of between virtual and real volumes. Meanwhile, by interpreting a failure-notification message received from the devices of the SAN, detected and outputted is an influence upon an access to a real or virtual volume as to the failure. Furthermore, when a plurality of failure notifications are received from the devices connected to the SAN, a plurality of failure notifications are associatively outputted depending upon a correspondence relationship between real and virtual volumes.
