Novel alkali-resistant cellulases which have an optimum pH at a neutral region and have a high relative activity in an alkaline region are produced by microorganisms belonging to the genus Bacillus and growing in neutral medium.The cellulases suffer little inhibition by means of detergent ingredients such as surface active agents, proteinases and chelating agents. Therefore, they can be conveniently used as one of ingredients for detergent compositions.

A method for melting and reducing chrome ore, which comprises charging chrome ore and carbonaceous material, and blowing in oxygen gas under a pressure ranging from 1 to 600 Torr, while molten metal is being stirred by a stirring gas blown in. In this method, a reaction vessel capable of allowing top blowing and bottom blowing onto the molten metal and decreasing pressure within the vessel is employed. Chrome ore and carbonaceous material can be used in the form of lumps or powder. When powdered ore and material are used, they can be injected through a lance or a tuyere into the vessel.
摘要:
Hydrocarbons are reacted with a silver tri-halogenomethane sulfonate of the formula ##EQU1## wherein X, Y and Z each represents a halogen atom, to form the corresponding complexes, and then the thus formed complexes are decomposed to selectively separate the desired hydrocarbon components. The used silver tri-halogenomethane sulfonate also is recovered by the decomposition of the complexes.

A reactor metering pipe fixing device fixes a reactor metering pipe disposed in a reactor to a cylindrical outer surface of a jet pump diffuser and reduces stress that may be induced in a weld zone in the reactor metering pipe. An outer holding member 41 is held on the cylindrical outer surface 18a of a jet pump diffuser 18 by a C-shaped holding member 30. The reactor metering pipe 19 is clamped from radial directions by the outer holding member 41 and inner holding members 42 and 43. Wedges 44 and 45 are wedged into a gap between the cylindrical outer surface 18a and the inner holding member 42 and a gap between the cylindrical outer surface 18a and the inner holding member 43 to fix the reactor metering pipe 19 firmly to the cylindrical outer surface 18a.

Proposed is a disk controller capable of notifying that a hard disk drive needs to be replaced even when the power of such hard disk drive is turned off. When a controller is to control the supply of electrical power to a disk in the respective disk units, the controller turns off a green LED and turns on a red LED when a disk in a disk group becomes a replacement target disk, turns off the power of the replacement target disk by opening a power switch corresponding to the respective replacement target disks, turns on the disk power source by closing the power switch when the replacement target disk is replaced with a new disk, and recognizes information concerning the new disk.
摘要:
It is an object of the present invention to provide a storage apparatus that can suppress access performance degradation owing to processing of data deduplication. The storage apparatus according to the present invention acquires a sum of the access frequencies to each of redundantly allocated pieces of data, and performs the deduplication on the pieces of data having the sum of access frequencies less than a prescribed threshold (FIG. 10).

In a jet pump measurement pipe repair method according to the present embodiment, a breakage part of a measurement pipe horizontally fixed to a lower part of a jet pump provided in reactor water in a reactor pressure vessel is repaired. The method has: a step of cutting and removing the measurement pipe including the breakage part; a step of retaining a connection pipe for connecting the remaining measurement pipe on the jet pump by means of a clamp; and a step of connecting ends of the remaining measurement pipe by means of the connection pipe.
摘要:
At the time of initial start-up, two or more storage units are started as a start-up control unit so that the total power consumption will not exceed specified electric power.Upon initial start-up of additional chassis, a CPU 214 for a basic chassis 400 selects, based on predicted power consumption for additional chassis 410, 412, etc., N additional chassis as a start-up control unit so that total power consumption for the basic chassis 400 and the respective additional chassis 410, 412 as recognized by an external power source 600 will not exceed the specified electric power; and the CPU 214 then turns on auxiliary power switches 510, 512 for the additional chassis 410, 412 belonging to the selected start-up control unit.
