According to an aspect of the present invention, a language processing device has a text input section and an anaphora analysis section. The text input section acquires text data. The anaphora analysis section analyzes whether a correct anaphora relation is included in the text data acquired by the text input section. The correct anaphora relation has an anaphor and an antecedent corresponding to the anaphor.

The present invention provides an optical recording medium, in which levels of wobble signals extracted from a recording area formed snakily, a reproduction exclusive area and an impossible area are maintained constant. On DVD-RW, groove tracks are snakily formed on a groove section on which recording information is recorded, and pit strings where a plurality of phase pits wave are arranged on the impossible area and the reproduction exclusive area which prevent illegal copying. On the respective areas, pit depths (groove depths), duty of the pit strings and wobbling amplitudes are set according to predetermined conditions so that the output levels of the wobble signals extracted based on the wobbling amplitudes can be maintained constant on the respective areas. As a result, synchronous control can be made accurately at the time of recording and reproduction on/from the DVD-RW.

A SrTiO3:Pr phosphor includes a SrTiO3:Pr phosphor material and an additive having one or more elements selected from the group consisting of W, Mo and V in a form of an elemental substance and/or a compound. A total amount of one or more elements included in the additive is in a range from 0.1 wt % to 30 wt % of the SrTiO3:Pr phosphor. The additive is WO3 and a particle size distribution of WO3 is such that a weight of WO3 whose particle diameters are in a range from 0.2 to 0.4 μm is not less than 70% of a total weight of WO3. A fluorescent luminous tube includes the SrTiO3:Pr phosphor.

The present invention is intended to measure a three-dimensional position of a tracking object snapped by a camera. The invention is based upon a measuring device using an image provided with an image data input part for inputting an image of a tracking object snapped by a camera and a tracking part for calculating a position of the tracking object and the tracking part moves a frame for extracting image data based upon the image, extracts image data included in the frame from the image in each moved position, counts the number of pixels having a hue feature based upon the extracted image data, determines the position of the frame in which the counted number of pixels is maximum for every hue feature and calculates the position of the tracking object based upon the determined position of the frame.
