The ceramic sheets include a first ceramic sheet and a third ceramic sheet having a permeability lower than the permeability of the first ceramic sheet. The third ceramic sheet has an arrangement that is astride at least two of the coil conductor patterns adjacent to each other in a layering direction, in a section including a coil axis of the coil. As a result, DC bias characteristics of the open magnetic circuit type layered coil component are improved.

摘要： A high temperature denitration catalyst of a gas turbine single plant contains TiO2, at least one of WO3 and MoO3 and V2O5 of 0.5 wt % or less, preferably 0.2 wt % or less, or none of V2O5, and is optimized to be used in a temperature range up to a maximum 450 to 600° C. The used high temperature denitration catalyst is immersed into a V-containing water solution and dried and/or burned. An intermediate temperature denitration catalyst is produced containing a V2O5 component of 0.5 wt % or more, preferably 1.0 wt % or more, and is optimized for use in a temperature range of 250 to 450° C. This intermediate temperature denitration catalyst is re-used in a combined cycle plant after being modified or in other plants.
