Abstract: An information processing apparatus includes a processor configured to extract from one or more electronic documents viewed before by a user a region of interest on which the user focuses attention and create a thumbnail of an electronic document to be viewed by the user in accordance with the region of interest by extracting an image corresponding to the region of interest from the electronic document.

Abstract: An information processing apparatus includes an acquisition unit that acquires information on execution results of plural steps, for the plural steps included in a predetermined work; and an output unit that in a case where the predetermined work is modified, outputs information indicating a change before and after the modification is performed, for each individual step of at least some of the plural steps, based on the information on the execution results of the plural steps.

Abstract: An inexpensive and reliable thin-film multilayered electrode which is formable on a dielectric substrate such as a ceramic substrate. A thin-film multilayered electrode has thin-film conductors and thin-film dielectrics formed by alternately layering on a dielectric substrate with a predetermined dielectric constant. The dielectric constant for each of the thin-film dielectrics is selected such that the electromagnetic field created in the dielectric substrate and the electromagnetic field created in each of the thin-film dielectrics are substantially in phase with each other when the thin-film multilayered electrode is used at a predetermined frequency, and the film thickness of each of the thin-film dielectrics falls between 0.2 .mu.m and 2 .mu.m; and the film thickness of each of the thin-film conductors, other than a thin-film conductor formed most distant from the dielectric substrate, is thinner than the skin depth at the predetermined frequency.

Abstract: A thin-film multilayered electrode of a high frequency electromagnetic field coupled type is disclosed. The thin-film multilayered electrode comprises thin-film conductors and dielectric thin films alternately stacked on a dielectric substrate so that a plurality of TEM mode transmission lines are multilayered. A film thickness of each of the dielectric thin films is set so that phase velocities of TEM waves which propagate through at least two of the plurality of TEM mode transmission lines are made substantially equal to each other, and a film thickness of each of the thin-film conductors is set so as to be smaller than a skin depth of a frequency which is used so that electromagnetic fields of at least two of the plurality of TEM mode transmission lines are coupled with each other.

Abstract: A coordinate input apparatus. A pair of optical guide channel arrays each including a required number of parallel optical guide channels (11, 12) which contain optical scatterer (22) are superposed to form an input board (100) with the optical guide channels of the two arrays intersected at right angles. Light is detected which is scattered by the optical scatterer (22) in the optical guide channels (11, 12) corresponding to irradiation of one point on the input board by a light pen (10) and reaches end surfaces (11a, 12a) of the optical guide channels. The detected signals are processed to form a binary signal train representative of the coordinate of the light pen (10).

Abstract: A polymer optical circuit with optical lead-fibers which comprise a plurality of optical fibers, each one end portion thereof being embedded in a transparent polymer film formed on a substrate, and polymer optical waveguides formed in the film between the embedded ends of the optical fibers so that the terminal ends of the optical waveguides are connected with the embedded ends of the optical fibers; the substrate, polymer film, polymer optical waveguide and optical fibers being formed as an integrated unit. A process for fabricating this polymer optical circuit is also disclosed.
