A printer of the automatically interchangeable character wheel type includes a platen formed lengthwise of the printer to support one surface of a printing sheet, and a carriage guided so as to be reciprocally movable along the platen. The carriage carries thereon contain a housing for containing a character wheel therein, a first shift device for shifting the character wheel in the containing housing to a printing position, a printing hammer for impacting the characters of the character wheel in the printing position, and a second shift device for shifting an ink ribbon to a first position for printing and a second position for standby by the same motor that drives the first shaft device.

A failure diagnostic processing system including a checking element for achieving a diagnostic check with respect to sensors to produce first and second diagnostic signals regarding each sensor. The first and second diagnostic signals indicate whether or not a failure condition stands, respectively. Also included are counting element for achieving a count up and a count down selectively in response to the first and second diagnostic signals, respectively; an alarm element for providing an alarm indication in accordance with the count number of the counting element; and a recording element for creating a history of failure by recording the count number of the counting element where the count number exceeds a predetermined reference number for starting the record.
摘要:
Provided is a condensation reaction product solution which is particularly suitable for filling a trench formed on a substrate having a narrow width and a high aspect ratio. The condensation reaction product solution has a long pot life, superior trench-filling when used for trench-filling, and a low cure shrinkage, an excellent crack resistance and a HF resistance when cured and converted into silicon oxide. The condensation reaction product solution comprises (I) a condensation reaction product obtained by condensation reaction from a condensation component comprising (i) 40% by mass or more and 99% by mass or less in equivalent of condensate of polysiloxane compound derived from silane compounds represented by the general formula (1): R1nSiX14-n (wherein n is an integer of 0 to 3, R1 is hydrogen atom or a C1-10 hydrocarbon group, and X1 is a halogen atom, a C1-6 alkoxy group or acetoxy group) and (ii) 1% by mass or more and 60% by mass or less of silica particles, and (II) a solvent, wherein the silane compounds represented by the general formula (1) are two or more types of silane compounds comprising a tetrafunctional silane compound which corresponds to the case of n=0 in the general formula (1) and a trifunctional silane compound which corresponds to the case of n=1 in the general formula (1).
摘要:
The present invention allows distribution of load generated by a single VOL to multiple processor units, by dividing the VOL into a plurality of smaller fractions called sub-VOL and distributing their ownership to multiple processor units. The division of a VOL is performed by dividing the control information of the VOL for plurality of sub-VOLs and (A) assigning VOL ownership to a processor unit for processing the tasks that are related to complete VOL (e.g. VOL RESERVE command) and (B) assigning ownership of each sub-VOL to different processor units for processing tasks that are specific to that sub-VOL (e.g. Read/Write commands). Thus the load on a singular sub-VOL owner processor unit becomes only a fraction of the total load generated by the VOL. The present invention helps in achieving a relatively even distribution of load among processor units.
摘要:
In general, a DRAM is used as a cache memory, and when attempting to expand the capacity of the cache memory to increase the hit ratio, the DRAM is required to be physically augmented, which is not a simple task. Consequently, a storage system uses a page, which conforms to a capacity virtualization function (for example, a page allocatable to a logical volume in accordance with Thin Provisioning), as a cache area. This makes it possible to dynamically increase and decrease the cache capacity.

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.
摘要:
With a computer system having a host computer and first and second storage apparatuses, the second storage apparatus virtualizes first logical units in the first storage apparatus and provides them as second logical units to the host computer, collects configuration information about each first logical unit, and sets each piece of the collected configuration information to each corresponding second logical unit. The host computer adds a path to the second logical units and deletes a path to the first logical units. The second storage apparatus copies data stored in the first logical units to a storage area provided by the second storage device and associates the storage area with the second logical units.
摘要:
A path is formed between a host computer and storage apparatuses without depending on the configuration of the host computer and a network and a plurality of volumes having a copy function are migrated between storage apparatuses while keeping the latest data.A computer system includes a host computer and first and second storage apparatuses, wherein the second storage apparatus virtualizes a plurality of migration source volumes as a plurality of migration destination volumes and provides them to the host computer; and if the second storage apparatus receives an input/output request for each migration destination volume, it reflects data in each migration source volume via each migration destination volume and the host computer cancels a path to each migration source volume and registers a path to each migration destination volume; and if the second storage apparatus receives a write request, it writes write data to each migration destination volume and each migration source volume and migrates copy processing control information and data until the termination of migration processing.
