摘要:
A surface treated tin-plated steel sheet which has an alloy layer formed on the surface of a steel sheet, a tin plating layer being formed on said alloy layer with a remaining exposed portion of the alloy layer having an area of 30% or more of that of the alloy layer and, formed on said tin plating layer and said exposed portion of the alloy layer, a coating film containing P and Si in an amount of 0.5 to 100 mg/m2 and 0.1 to 250 mg/m2, respectively; and a chemical treatment solution for use in preparing the steel sheet which comprises a phosphate ion, a tin ion and a silane coupling agent and has a pH of 1.5 to 5.5. The surface treated tin-plated steel sheet is free from chromium which causes problems from an environmental view point, and also is excellent in adhesion with a paint, corrosion resistance after being coated, rust resistance, and formability.

摘要:
The tin-plated steel sheet includes a base steel sheet; a tin plating layer coating approximately more than 97.0% of the base steel sheet; and a chemical conversion coating having approximately 0.5 to 100 mg/m2 phosphorus and approximately 0.1 to 250 mg/m2 silicon formed on the tin plating layer and an unplated region corresponding to approximately less than 3.0%. The tin-plated steel sheet does not contain chromium which is harmful to the environment but has superior overcoat adhesion property, discoloration resistance, and rust resistance.

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.
摘要:
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.
