Abstract: A file reconstruction device includes an extraction unit and a creation unit. The extraction unit extracts pages conforming to a predetermined condition, from an input file including plural pages. The creation unit creates an output file including the two or more conforming pages extracted from the input file by the extraction unit.

Abstract: An information processing apparatus includes a reference data acquisition unit acquiring reference data representing a reference work time for each of work processes, an area data acquisition unit acquiring area data representing an area on a medium having entry fields, each of which corresponds to one of the work processes and one of which is provided for the area, an entry data acquisition unit acquiring entry data representing stroke coordinates information representing a stroke made on the medium by a user, and a time when the writing was performed, a specifying unit specifying the entry field in which the user performed writing and the time when the writing was performed, a calculation unit calculating a work time required for each of the work processes, and an evaluation unit, for each of the work processes, comparing the reference work time with the work time and evaluating the work.

Abstract: A surface-modified plastic film, comprising: a surface layer composed of minute filamentous forms and/or granular forms consisting of a composition containing a resin and/or inorganic microparticles, on at least one major surface of a substrate plastic film. Preferably, the surface-modified plastic film is characterized in that the minute filamentous forms have a diameter of 100 ?m to 1 nm.

Abstract: An adhesive tape made of polyvinyl chloride consisting essentially of a vinyl chloride resin film (hereinafter referred to as "PVC film") which contains from 5 to 60 parts by weight of inorganic fine particles having an average particle size of from 0.1 to 10 .mu.m per 100 parts by weight of the vinyl chloride resin and which has a thickness of from 50 to 200 .mu.m, and an adhesive layer formed on at least one side of PVC film, wherein a plurality of linear channels having a transverse cross section of V-shape or U-shape are formed on at least one side of the film in parallel to one another in the width direction of the adhesive tape, and, in the cross section of each channel, angles A and B which are angles of the respective opposing two inclined sides of the V-shape to the film plane, or which are angles of the tangential lines drawn at a 1/2 position in the depth of the channel on the respective opposing two curved sides of the U-shape, to the film plane, satisfy the following formulae 1 to 4:A.ltoreq.B.
