Abstract: A first calculator calculates a relative position and a relative attitude of a vehicle based on a plurality of images captured by an image capturing apparatus mounted on the vehicle. A second calculator extracts one marker from an image captured by the image capturing apparatus, and calculates an absolute position and an absolute attitude of the vehicle based on a position and an attitude of the one extracted marker. A corrector corrects the relative position and the relative attitude based on the absolute position and the absolute attitude to generate a corrected position and a corrected attitude of the vehicle. The corrector determines whether or not the vehicle is turning, and generates the corrected attitude not using the absolute attitude calculated during a period in which the vehicle is turning, but using only the absolute attitude calculated during a period in which the vehicle is not turning.

Abstract: A hollow cylindrical depth filter formed of fibers of a thermoplastic resin and having a thickness of a filter medium of 5 to 25 millimeters, in which the filter medium has a compression ratio of 0.2 or less when a load of 0.5 MPa is applied thereto, the filter medium has a fiber layer of at least three layers from a fluid inflow side toward an outflow side, porosity of the three layers are adjusted to a specific range, respectively, and intersection points of the fibers forming the filter medium are bonded, a mean interval between the intersection points is 2 to 100 times a mean fiber diameter of the fibers in a length direction, and a ratio of the mean fiber diameter on a surface on an upstream side to the mean fiber diameter on a surface on a downstream side of the filter medium is 0.9 to 1.2.

Abstract: A first calculator calculates relative position and attitude of a vehicle based on images captured by an image capturing apparatus on the vehicle. A second calculator extracts one marker from a captured image, calculates absolute position and attitude of the vehicle based on a position and an attitude of the one extracted marker, and calculates an angle of a direction of the vehicle 1 with respect to a normal line to a plane of the one marker 4 based on a position and an attitude of the vehicle 1 in a marker coordinate system. A corrector generates a corrected position and attitude, not using the absolute position and attitude calculated based on the marker for which the angle is not larger than a first threshold, but using the absolute position and attitude calculated based on the marker for which the angle is larger than the first threshold.

Abstract: With the purpose of developing a widely applicable technique capable of preparing oral granular formulations having good handling properties and rapidly disintegrating or dissolving in the mouth during administration or when they are dissolved or suspended before use, the present invention provides oral granular formulations containing no or little binders and having fast-disintegrating or -dissolving properties.

Abstract: Oral antibacterial compositions contain a penem or carbapenem antibiotic in combination with an absorption improver selected from substances capable of inhibiting the dipeptidase localized on/in epithelial cells of the small intestine, cilastatin, glutathione and N-acetyl-L-cysteine. Gastrointestinal absorption of the penem or carbapenem antibiotic can be improved by orally administering the absorption improver in combination with the antibiotic.
