Abstract:
The storage system includes a data dividing means for dividing writing target data into a plurality of units of partial data, and generating units of new divided file data; an index file generation means for generating, for each of the units of partial data, an index entry, and generating index file data by adding test data for error detection; a data writing means for writing the divided file data and the index file data; and a recovery means for detecting an error in the index entries written in the storage device, based on the test data included in each of the index entries. The recovery means deletes an index entry in which an error is detected and all of the subsequent index entries in the index file data stored in the storage device, from the index file data.

Abstract:
A piston coupled to a piston rod is inserted in a cylinder, and an outer cylinder is disposed around the cylinder so as to define a reservoir therebetween. A separator tube is disposed around the cylinder so as to define an annular passage therebetween. The piston rod is locked and unlocked so that a movement of the piston is prevented and allowed, by closing and opening an electromagnetic open/close valve so as to block and allow a flow of hydraulic fluid through a flow passage between the annular passage and the reservoir. The separator tube has a greater thickness. O-rings are disposed so as to provide seals between the separator tube and the cylinder. The separator tube extends to positions such that the ends of the separator tube overlap a base valve and a rod guide, thereby holding the respective ends of the cylinder. Due to this configuration, it is possible to prevent deformation of the cylinder and the separator tube due to an increase in the hydraulic pressure, and improve the pressure resistance.
Abstract:
A gas supply apparatus measures a first pressure inside a first body cavity of a specimen and a second pressure inside a second body cavity of the specimen. The gas supply apparatus regulates a pressure of a predetermined gas based on the measured first and second pressures inside the first and second body cavities so that the first and second pressures reach predetermined first and second pressure settings, respectively.

Abstract:
According to an exposure apparatus and an exposure method in the present invention, based on a focus value and a leveling value in each exposure shot calculated based on measurements by a focus sensor, differential absolute value for respective value are calculated. The differential absolute values for the focus values and leveling vaule are compared with predetermined threshold vaule for the respective differential absolute values. When the differential absolute values exceed the threshold value, it is determined that an exposure abnormality exists. In such case, based at least the number of exposure area where the exposure abnormality is occurred and distribution of the exposure area where the exposure abnormality is occurred on the object to be exposed, a kind of the exposure abnormality is identifed. The detection of the exposure abnormality is assured, and a cause of the abnormality is determined without lowering manufacturing capabilities and increasing in cost.
