Abstract: The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.

Abstract: A corrosion resistant member has a chemical conversion treatment film with a two-layer structure formed atop a metal substrate plated with zinc or zinc alloy plating. The two-layer structure comprises a lower layer containing Cr formed on the surface of the plating and an upper layer containing SiO2.

Abstract: A high temperature gas pipe (4) from a combustion furnace to a turbine (2), having a high temperature gas shut-off valve (10a); a high pressure air leading passage (9) from a compressor (3); a first air passage (7a) connecting the high pressure air leading passage (9) and a downstream portion of the high temperature gas shut-off valve (10a) of the high temperature gas pipe (4) via a first air selector valve (8a); and a second air passage (7) connecting the high pressure air leading passage (9) and a high pressure air pipe (6) to the combustion furnace via a second air selector valve (8b) are provided within a chamber (5). Further, the high temperature gas shut-off valve (10a) and the first and second air selector valves (8a, 8b) are driven by a single valve shaft (12).

Abstract: A zincate type zinc alloy electroplating bath which comprises a Zn compound, an alkali hydroxide, a salt of Fe(II, III) or Ni(II), a chelating agent for dissolving said salt of Fe(II, III) or Ni(II) and brightening agents. The chelating agent is selected from the group consisting of a commercially available chelating agent and a reaction product of a mixture of one or more kinds of aliphatic amine with epihalohydrin. The brightening agents contain alkylated polyalkylene polyamine in which some of the basic nitrogen atoms of polyalkylene polyamine are alkylated by alkyl groups of C.sub.1 to C.sub.3, and one or more compounds selected from the group consisting of reaction products of imidazole or its derivative with epihalohydrin and reaction products of imidazole or its derivative with epihalohydrin in the presence of aliphatic amine.
