摘要:
A computer system including: at least one host computer, a storage system for storing data used in the host computer, and a managing computer for managing storing the data in the storage system which are connected to each other with a network. The managing computer monitors the journal volume which is a storing destinations of the journal, in a case that the journal is stored in the journal volume in parallel, when it is detected that the storing destination of the journal changes from one of the groups into which the journal is just stored to another group, transmits an instruction to the storage system to change the storing destination of the journal to another group.

Provided is a process for producing a high-purity α-alumina in which an Si content, an Fe content, a Ca content, and an Na content are simultaneously removed. The high-purity α-alumina is produced by burning aluminum hydroxide having an Na content of 0.11 mass % or less, an Fe content of 6 ppm or less, a Ca content of 1.5 ppm or less, and an Si content of 10 ppm or less as impurities in terms of alumina respectively, and having an average particle diameter of 55 μm or less at a burning temperature of 1,100 to 1,500° C. by using a burning vessel containing Al2O3 in a range of 85 to 93 wt % and SiO2 in a range of 7 to 14 wt % and subjecting the obtained α-alumina to wash treatment.

Disclosed is a low-cost, inverter-integrated electric compressor with which a high degree of design freedom is maintained, high vibration resistance can be achieved by reliable anchoring of the circuit components, the weight can be reduced easily, and which has excellent operational stability. An inverter-integrated electric compressor has a built-in motor and has a substrate provided with a motor drive circuit including an inverter. In the inverter-integrated electric compressor, after electric components including the substrate have been fixed in a housing space surrounded by a compressor housing and have been assembled, the housing space is filled with an insulating resin, and at least a part of the electric components are sealed by the solidified filling resin. The inverter-integrated electric compressor is characterized in that a resin frame, which has a concave retaining part provided with a concave part formed in a concave shape along the outlines of the circuit components provided on the substrate and has a vent hole provided in the concave retaining part, is mounted on the substrate, and a resin injection space, which can be filled with resin, is formed between the circuit components on the substrate and the resin frame.

There is provided a method for manufacturing a patterned magnetic recording medium including a step of completely removing an etching resist on a magnetic layer 3, which is used for etching the magnetic layer 3, without deteriorating magnetic characteristics of the magnetic layer 3. The step of removing the etching resist used for etching the magnetic layer 3 includes the steps of irradiating the etching resist on the magnetic layer 3 or the first protective layer 4 with an excimer VUV laser under a reduced pressure and immersing the resist coating 5 remaining on the magnetic layer 3 or the first protective layer 4 into a resist removing agent solution to wash off the resist coating 5.

The present invention decreases the burden of operation required for specifying the continuity status and the cause of failure of a network storage device. A host computer accepts the specification of the device identifier, that is an identifier of the network storage device in the host protocol which positions in a higher hierarchy than the network communication protocol, and a volume identifier, that is an identifier of the volume. Then based on the specified device identifier, the host computer specifies the network identifier, that is an identifier of the network storage device in the network communication protocol. And continuity is confirmed in the network communication protocol in which the specified network identifier is the destination. Also continuity is confirmed in the host protocol in which the device identifier is the destination. And the volume specified by the volume identifier is accessed.
摘要:
A bimorph switch electrically connecting a traveling contact and a fixed contact. The switch comprises a substrate having a front face, a rear face, and a through hole penetrating from the front face to the rear face; a fixed contact extending from an edge portion of the aperture of the through hole towards the inside of the aperture; and a bimorph section holding the traveling contact at a position facing the aperture and driving the traveling contact. One end of the bimorph section may be formed on a silicon oxide layer formed on a front face of the substrate.
