摘要:
A substrate processing apparatus that performs processing by immersing a substrate into a processing liquid obtained by mixing phosphoric acid with a diluent includes a concentration sensing means for sensing the concentration of the processing liquid by measuring the absorbance characteristics of the processing liquid. The concentration sensing means includes a light-transmitting section that introduces the processing liquid into the inside to let the processing liquid pass therethrough, a light-emitting section that radiates light having a predetermined wavelength to the light-transmitting section, a light-receiving section that receives the light therefrom via the light-transmitting section, a first lens that condenses the light emitted from the light-emitting section to the light-transmitting section, a second lens that condenses the light that has passed through the light-transmitting section to the light-receiving section, and a cooling mechanism that cools at least one of these.

A data control apparatus includes a mapping-table managing unit that manages a mapping table that is associated with a corrupted-data recovery function of recording data and error correcting code data as redundant data that is given separately from the data, distributed and stored in units of stripe blocks in the plural nonvolatile semiconductor memory devices, the mapping table containing arrangement information of the data and the error correcting code data; a determining unit that determines whether to differentiate frequencies of writing the data into the semiconductor memory devices; and a changing unit that changes the arrangement information by switching the data stored in units of the stripe blocks managed using the mapping table to differentiate the frequencies of writing the data into the semiconductor memory devices, when the determining unit determines that the frequencies of writing the data into the semiconductor memory devices are to be differentiated.

A size storage unit stores therein a block size of a memory element. A buffering unit executes buffer processing configured to store data received from a RAID (Redundant Arrays of Inexpensive/Independent Disks) controller into a buffer, and to write the data stored in the buffer into the memory element. A stripe-size receiving unit receives a stripe size that indicates a size of a unit of access at time of access to the memory element by the RAID controller. Writing processing is configured to write data received from the RAID controller into the memory element without executing the buffer processing by the buffering unit, when the stripe size is n times of the block size (n is a positive integer).
摘要:
A RAID is configured using plural nonvolatile semiconductor memory devices to enable recovery of data stored in the nonvolatile semiconductor memory devices, and data is read from the nonvolatile semiconductor memory device included in the RAID in response to a data reading request inputted from outside. When an error occurs during the reading, data for which the reading error occurs is recovered, and rewritten into an area of the nonvolatile semiconductor memory device in which the reading error occurs.

In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices. Server side data transfer devices and client side data transfer devices can be provided in multiple-to-one, one-to-multiple, or multiple-to-multiple manners.

Even when the name corresponding to the data is not registered so that it is impossible to transfer the corresponding name instead of transferring the data, it is possible to reduce the amount of transfer data among the data transfer devices by transferring the compressed data in which this data is expressed in a compressed form by utilizing the name corresponding to the registered reference data.

摘要:
A common electrode plate formed on a common electrode base attached to the lower surface of the movable stage faces a split electrode plate formed on a split electrode base attached to the upper surface of a main base, which are apart from each other at a predetermined interval. A support mechanism formed of ball bearings, ball stoppers at the movable side, steel balls, ball stoppers at the fixed side, and ball bearings allows the movable stage to move in directions of the X-axis, Y-axis and turning. A linear actuator 19 is driven to move the movable stage in the directions of X-axis, Y-axis, and turning.
