Inorganic fibers including the following composition, SiO, AlO, MgO and CaO being main components, and the inorganic fibers being produced by a melting method: SiO: 3.0 wt % or more and less than 48.0 wt %, AlO: more than 20.0 wt % and 80.0 wt % or less, MgO: 1.0 wt % or more and 50.0 wt % or less, CaO: 1.0 wt % or more and 50.0 wt % or less, and FeO: 0.0 wt % or more and less than 1.0 wt %.

Biosoluble inorganic fiber

Inorganic fibers including the following composition, SiO, MgO and CaO being main components: SiO: 73.6 wt % to 85.9 wt %, MgO: 9.0 wt % to 21.3 wt %, CaO: 5.1 wt % to 12.4 wt %, AlO: 0 wt % or more and less than 2.3 wt %, and FeO: 0 wt % to 0.50 wt %.

Bio-soluble inorganic fiber

Disclosed herein is a bio-soluble inorganic fiber with high tensile strength, manufactured in a method comprising: heating and melting a raw material which includes, on a weight basis, 60 to 80 percent of SiO, 5 to 20 percent of MgO, 5 to 30 percent of CaO, 0.5 to 5 of AlO, and 0.1 to 5 of BaO, at a temperature of 1800 to 2100 degrees Celsius; and exposing the melting material to an air flow for fiber forming.

Inorganic fiber and method for manufacturing the same

The object of the present invention is to make information necessary for judging whether control output is possible closer to the latest information than in the conventional method or made the latest, and shorten the time from control start to control execution. In a control and monitoring system for a power system which controls monitoring control objects by supplying a control instruction from a master unitto a plurality of input/output terminal devices BCUBCUand so on provided for each of the plurality of monitoring control objects in a power system, the master unitstarts operations to acquire information necessary for judging whether control output to the input/output terminal devices BCUBCUand so on is possible at the time of control object selection notification from the master unitto the input/output terminal devices BCUBCUand so on.
