Reliability is evaluated in constructing a component based-on application and an application for realizing reliability required can be constructed efficiently. A run-time history such as an occurrence frequency of errors, a recovery time required at error occurrence, and a processing capacity at preventive maintenance is added per software component to a run-time history list having been recoded per execution environment such as an application ID, combined component IDs, and executed hardware ID. From these pieces of information, an interval of performing preventive maintenance recommended per software component during system construction is calculated. By comparing reliability per software component and reliability required for the system, advisability is determined and conformance is evaluated. An execution schedule for preventive maintenance and a processing capability are calculated about the entire component-based application created by combining the software components. By calculating the reliability and the processing capability in the entire system to be compared to those required for the entire system, advisability is determined and conformance is evaluated.

摘要:
The phosphate-treated zinc-coated steel sheet has: a steel sheet; a zinc-coating layer of a single η-phase containing Ni in a range from 10 ppm by mass to solid solution limit, being formed on at least one side of the steel sheet; and a phosphate-treated layer containing Mg in a range from not less than 0.1% by mass to less than 2.0% by mass, being formed on the zinc-coating layer. The steel sheet without treated by sealing has corrosion resistance equivalent to or higher than that of conventional products treated by sealing, and also has excellent blackening resistance.

A mixed irradiation evaluation support system for supporting judgment and determination of allocation of contribution in mixed irradiation using proton beams and X-rays. According to a composition ratio designated by a composition ratio scroll bar 107, a dose distribution by a proton beam and a dose distribution by an X-ray are composed, and the result of the composition is displayed three-dimensionally in a three-dimensional display part 104. Further, when a cross section is designated in the three-dimensional display part 104, an isodose map 115 in the designated cross section is displayed in a cross section window 114.

The high tension steel sheet includes 0.1 wt % or more of silicon and has a zinc-plating layer thereon. When sputtering analysis is performed in the depth direction from the surface of the high tension steel sheet after the zinc-comprising-plating layer is removed by dissolution, a surface-concentrated Si index X defined by the formula, X=(the maximum intensity A of Si on the surface of the high tension steel sheet/the average intensity B of Si in the steel)×the content of Si in the steel sheet on a wt % basis, is 12 or less.

In connection with a process of implementing galvanizing and galvannealing on steel strips containing highly oxidizable elements such as Si, Mn, P, Ti, Nb, Al, Ni, Cu, Mo, V, Cr, and B, after annealing in a continuous line or implementing electroplating after annealing, the present invention provides a method for restraining non-plating at low cost in a stable manner and a surface treated steel strip having minimal non-plating. By applying on at least one surface of a steel strip a Fe plating having a coating weight of 0.1-10 g/m.sup.2 and an oxygen content of 0.1-10 wt %, followed by annealing and then zinc or zinc alloy plating, there is obtained a surface treated steel strip having minimal plating defects which includes a Fe plating layer immediately below a zinc or zinc alloy plating layer and a steel alloying element concentrated stratum immediately below the Fe plating layer. The Fe plating may be formed using an electroplating bath which contains 0.1-10 g/l of Fe.sup.3+ and a carboxylic acid or an alkali metal salt thereof.

摘要:
A novel plasmid pEAP2, which was constructed from Bacillus sp. 170 chromosomal DNA carrying the gene for extracellular production of penicillinase and a vector plasmid pMB9. A novel microorganism, Escherichia coli HB101(pEAP2) carrying the plasmid pEAP2 and being capable of extracellular production of penicillinase. The method for cultivation of the microorganism is characterized by culturing it in the medium containing NaCl (or KCl) for 16-48 hours. According to this invention, useful high-molecular substances can be produced in a high yield.
