摘要： A structure and method of arranging recursively derived data items in a database. A set of hierarchical iteration levels, one for each iteration of the recursive relation from which the data items are derived, is provided and all data items derived during a given iteration are associated with the corresponding iteration level. Also provided is an index structure including an index set of non-leaf nodes, a sequence set of leaf nodes, and an iteration level index. The leaf nodes include a record of the iteration level of each data item. The data are globally linked according to iteration level or are clustered on pages which are linked according to iteration level. Highly efficient scan and search are implemented by utilizing the iteration level index and the record of iteration level in the leaf nodes to direct the scanning and searching to data generated during a single iteration. The least fixpoint of a set of mutually recursive relations is efficiently calculated by these methods.

摘要： An active paper drop mechanism (20) for ink-jet printers is provided. The mechanism comprises a pair of opposed, movable rail members (22) associated with opposed walls (14) of a horizontally-disposed output collection tray (12) for receiving sheets (10) of printed media. In particular, each rail member is provided with return spring (26) that act to maintain the rails in a closed position. In that position, the rails support a sheet of the print medium during the printing operation, thus giving the ink on the previously printed-on sheet (10 min ) time to dry. The rails are provided with a wing member (32) and are pivotally secured (38) in the floor of the output tray, with the pivot point spaced inwardly from the wing member. Downward pressure against the wing member thus causes the rail to rotate outward from its closed position, into a recess (24) provided in the side of the output tray. This provides sufficient clearance for the sheet to drop into the output stack. Upon release of the downward pressure, the spring causes the rail member to return to its original closed position.
