摘要:
A high heat-resistant catalyst includes: noble metal particles; first compounds which contact the noble metal particles and suppress movement of the noble metal particles; and second compounds which envelop the noble metal particles and the first compounds, suppress the movement of the noble metal particles, and suppress coagulation of the first compounds following mutual contact of the first compounds. The first compounds support the noble metal particles, and single piece or aggregate of the first compounds supporting the noble metal particles are included in a section partitioned by the second compounds. A coefficient of linear thermal expansion of the second compounds is 1.2×10−5 [K−1] or less.

A catalytic converter includes: a three-dimensional structural support having a plurality of cells partitioned by porous cell walls, in which a pore diameter of the cell walls is 10 μm to 50 μm and porosity of the cell walls is 40 vol % or more; and a catalyst-coated layer containing a catalyst component. The catalyst-coated layer is coated on surfaces of the cell walls of the three-dimensional structural support. 50 mass % or more of a total supported amount of the catalyst component on the three-dimensional structural support is present in a region from the surfaces of the cell walls of the three-dimensional structural support to surfaces of the catalyst-coated layer.

Herein is provided a fibrous catalyst having a catalytic layer containing particles comprising ceria CeO2, with an average particle size of 1 nm to 1 μm. The layer is coated on the surface of a ceramic fiber. Accordingly, flexibility of the surface of the catalytic layer is improved due to the decreased interaction between the particles due to their minute size. Because flexibility is improved, vibration and deformation does not deteriorate the layer, and as such, the peeling-resistance property is improved.

A parent workstation 1 has a master file updating section 4 for updating master files 7, a delivery start notifying section 5 for forwarding the directory list of the master files 7 to a child work-station, and a master delivery section 6 for forwarding data or information requested by the child workstation; and the child workstation has a slave file updating section 11 for updating slave files 14, an updated asset registering section 12 for forwarding updated data or information to the master files 7, and a slave delivery section 13 for comparing the contents of the directory list of the master files 7 and those of the directory list of the slave files 14, and requesting the parent workstation 1 to forward the data or information which is found different.
摘要:
In a program specification data transfer method for program development support system according to the present invention, if a program specification data program is updated in the editing by the specification data edit unit at the terminal, then the update flag of the applicable specification data program is set to indicate the existence of update by the update flag set unit. The updated data extract unit checks the update flag to extract the updated program specification data alone and thus extracted updated program specification data is transferred to the work file at the host computer. The specification data merge unit merges the updated program specification data stored in the work file with the program specification data in the program specification data file at the host computer and stores the merged result to the program specification data file.
