A conferencing system prevents useless data processing that accompanies data communication from occurring even when a presenter's device that outputs image data is switched. A projector functions as a node in a tree structural network, and projects an image corresponding to image data and sends the image data to the direct child indicated in parent-child information when receiving the image data from the direct parent indicated in the parent-child information. A switching module, when receiving a switching request for making a request to switch a parent-child relationship from the direct child, sends the switching request to the direct parent, when receiving permission information representing permission to switch from the direct parent, sends the permission information to the direct child that sent the switching request and changes the parent-child information so that the direct parent becomes the direct child and the direct child that sent the switching request becomes the direct parent.

The present invention provides high strength thick steel plate superior in crack arrestability high in strength, free of deterioration of HAZ toughness, and free of anisotropy, that steel plate containing, by mass %, C: 0.03 to 0.15%, Si: 0.1 to 0.5%, Mn: 0.5 to 2.0%, P: &#x2266;0.02%, S: &#x2266;0.01%, Al: 0.001 to 0.1%, Ti: 0.005 to 0.02%, Ni: 0.15 to 2%, and N: 0.001 to 0.008% and having a balance of iron and unavoidable impurities as chemical components, having a microstructure of a ferrite and/or pearlite structure with bainite as a matrix phase, and having an average circle equivalent diameter of crystal grains with a crystal misorientation angle of 15&#xb0; or more of 15 &#x3bc;m or less in the regions of 10% of plate thickness from the front and rear surfaces and of 40 &#x3bc;m or less in the other region including the center part of plate thickness.

High strength thick steel plate superior in crack arrestability

Substrate-selecting equipment selects substrates used for objective products from among a group of substrates with photosensitive material layers used for the production of photomask. The substrate-selecting equipment comprises one or more of the defect-registering part(s) for registering the results of the inspection of defects of substrates with photosensitive material layers in database, the photosensitive material layer lot check result-registering part for registering the results of check of lots of photosensitive material layers in database and the substrate-selecting part for selecting substrates used for the production of objective products from among a group of substrates with photosensitive material layers, on the basis of the results of inspection of defects and the results of check of lots of photosensitive materials registered in database.
