Abstract: A light irradiation device for applying light to a target object under relative movement includes: a base; first light-emitting element groups located on an upstream side in a direction of object movement, and second light-emitting element groups located on a downstream side, which are arranged on one main surface of the base; and first lenses and second lenses which cover the respective first light-emitting element groups and the respective second light-emitting element groups, respectively. An optical axis of light emitted through each of the first lenses is inclined toward the downstream side in the direction of object movement with respect to a normal to the one main surface of the base. An optical axis of light emitted through each of the second lenses is inclined toward the upstream side.

Abstract: Provided is a railway vehicle disc brake apparatus that is capable of ensuring sufficient strength to withstand a reaction force from a disc, and that can be reduced in weight. A caliper lever of the railway vehicle disc brake apparatus has a pair of working point side arms, and a working point section. The working point section links the pair of working point side arms, and holds a pad via a working point shaft. The pair of working point side arms are inclined in such a manner that the interval therebetween narrows as the working point side arms approach the working point section. Furthermore, each working point side arm is inclined with respect to a reference plane that is perpendicular to the direction in which the working point section extends.

Abstract: To improve the data compression ratio in the data compression/decompression method utilizing the down-sampling process. Image data in a DS area division unit (130) is divided into a plenty of DS areas and DS areas which are not important are converted into contracted data of the block size by down-sampling in a down-sampling unit (131). A relocation unit (132) allocates two or more contracted data in one DS area, inserts file data into the other portion in the DS area, and removes the DS area where no contracted data is allocated, thereby reducing the entire image size. The image data thus contracted is inputted into a JPEG encoder (14) and subjected to a DCT process and a quantization process for each block. When performing restoration, decompression is performed by the JPEG decoder and the original location is restored. As for the contracted data, interpolation is performed to restore the image data.

Abstract: The present invention provides an osteoporosis diagnosis aiding apparatus that utilizes a panoramic radiograph. A digitalized image of the panoramic radiograph enters a personal computer (S210). The cortical bone at the lower edge of the mandibular molar in the panoramic radiograph is specified with a mouse to make that part a target of examination (S220). This extracted image is subjected to the following image processing. (1) Subject the image to median filtering so as to reduce noises throughout that image. (2) Find a skeleton constituted by micro-structural elements (S230). (3) Extract only components parallel to the tilt of the lower edge of the mandible (S240). (4) Binarize the image using Otsu's linear discrimination method, for example (S250). The binarized lines are then classified into three groups according to size, and can be determined as a risk of osteoporosis in a case where there is more than just a single line classified in the largest line group aside from the smallest line group.
