摘要： The present invention provides a titanium material for hot rolling that enables reduction of defects occurring on the surface (in the case of a flat material or strip coil, including not only the flat surfaces but also the side surfaces and edges) owing to the hot rolling, and a method of producing the same, particularly to a titanium material for hot rolling enabling omission of an ingot breakdown process, and a method of producing the same, characterized in that it is a titanium material for hot rolling having dimples imparted by cold plastic deformation whose mean value of the heights (Wc) of the undulation profile elements is 0.2 to 1.5 mm and mean value of the lengths (WSm) thereof is 3 to 15 mm, and makes it possible to minimize surface defects occurring in hot rolling even if a process for breaking down the ingot is omitted. The dimples are formed by plastically deforming the surface of the titanium under cold condition using a steel tool having a tip shape of a radius of curvature of 3 to 30 mm or a steel sphere of a radius of 3 to 30 mm.

摘要： A document capture system may automatically capture documents and/or financial information for a user. The document capture system may capture and save documents a user views in a web browser. A user may visit various web sites to view financial data and a document capture plug-in module installed in the web browser may capture or save the viewed document. The document capture system may capture financial data while the user is visiting web sites normally—that is, not just when the user if visiting them particularly to collect financial data. The document capture system may be configured to automatically detect when the user views certain documents and may be configured to continually monitor the user's web activity in order to capture financial documents whenever the user visits certain sites. The document capture system may include a list of URLs representing web sites or documents that should be automatically captured.
