Abstract: The present invention provides a document verification system capable of verifying whether a document is an original at low cost and with ease. A terminal device acquires, as a registered feature vector feature information indicating a feature of a nonreproducible disorder portion in a printing region on a document serving as the original, and stores the registered feature vector on a hard disk via the Internet. A server acquires, as a calculated feature vector the same information as the registered feature vector in a document to be verified as to whether the document is the original, reads out the registered feature vector from the hard disk, compares the acquired calculated feature vector with the read out registered feature vector, and verifies whether the document to be verified is the original on the basis of a result of the comparison.

Abstract: Each of optical fibers has a core and stress applying members disposed around the core. End portions of the optical fibers are mounted on a fusion-splicing apparatus, and aligned through the image observation from two different lateral directions of the optical fibers. Then, a distance between positions of a bright portion end and a luminance peak closest to the bright portion end is obtained on each bright portion end of a luminance distribution of the optical fiber obtained from at least one picked-up image. The optical fibers are fusion-spliced by aligning the stress applying members so that the sum of the distances is adjusted to be minimum. Alternatively, a distance between positions of the luminance peaks respectively closest to the respective bright portion ends is obtained and the optical fibers are fusion-spliced by aligning the stress applying members so that the distance is adjusted to be maximum.

Abstract: The invention is directed to an absorbent article, which is preferably a sanitary napkin or a pantiliner, comprising: a body contacting layer; a garment contacting layer; and an absorbent core disposed between the body contacting layer and the garment contacting layer. The absorbent core has a core edge. The core edge defines a core region within the core edge and an outer region outside the core region. The body contacting layer and the garment contacting layer extend outward into the outer region and joined together in the outer region. In one aspect of the invention, the garment contacting layer has a graphic printed on the body facing surface at least in a portion of the outer region. In another aspect of the invention, the body contacting layer has a graphic printed on the garment facing surface at least in a portion of the outer region. The body contacting layer has a first light transmittance so that the graphic can be seen through the body contacting layer in the outer region.

Abstract: The present invention provides a detection apparatus, an input apparatus, an individual identification apparatus, and a recording medium that utilize information about users' bodies which disables the fraud of impersonating authorized users and is extremely difficult to forge and is obtained without giving the users a sense of inhibitions, without restraining their bodies during use, and independent of their mental states and health. A FIFO memory outputs, as one set of features, a total of 60 voltage values, which are broken down as 20 voltage values sampled every 12.5 ms (80 Hz) before the instant when timing is inputted at the peak position of an amplitude waveform signal generated by one click operation, 39 voltage values sampled every 12.

Abstract: A three-dimensional object identifying system is disclosed which identifies a three-dimensional shape object optically such as a part of a human body for preventing an information apparatus such as a personal computer from being used by any other illegitimate user than a legitimate user. The three-dimensional object identifying system has a function generating unit which generates modulation signals, light emitting elements which emit lights based on the modulation signals to a three-dimensional object, light receiving elements which receive reflected lights from the three-dimensional object and which produce detection signals, a correlation detecting unit which detects correlation information between each detection signal and modulation signal, and an identifying unit which performs identifying processing for the three-dimensional object on the basis of both pre-cataloged correlation information and the detected correlation information.

Exposing unit exposes the photoconductive layer to write image into the light-controlling layer. Gradation control unit modulates the output light of the exposing unit on the basis of a signal indicative of the multi-level density of the image to be written, thereby controlling the light transmittance of the light-controlling layer.

Abstract: A heating sensor is disposed within a pipe with a clearance between an inner wall of the pipe and an outer surface of the heating sensor such that a measurement of thermal conductivity is free from any influence of a convective heat transfer. Temperatures of the fluid and the heating sensor are measured and a differential temperature therebetween in steady state heating is determined. A correlation is established between the differential temperature and a thermal conductivity of the fluid and is utilized to obtain the thermal conductivity of this fluid.
