A chart original in which two or more patterns are disposed so as to be separated at predetermined intervals and are symmetric with respect to a second imaginary line which is orthogonal to a first imaginary line. Each of the patterns is formed from a first line segment, which is orthogonal to the first imaginary line, and two second line segments, which are disposed at opposite positions with respect to the first line segment so as to intersect the first line segment. Each of the patterns intersect the first imaginary line at three points.

Disclosed herein is a self-servo writing method that uses the head of a disk drive to write servo data on a disk-shaped medium. This method calculates an accurate position offset between the read-head element and write-head element incorporated in the head, by using the positioning servo data and measuring servo data that are recorded on the disk-shaped medium.

When a small pliers is pulled out to take substrate G from the cartridge C, the sensor 9 located at position P will draw a track T to move one side passing through one side(Ga) of substrate G. Thus, the position for having a perpendicular direction (Y direction) between the held substrate G and the moving forward/backward direction of small pliers 43 can be calculated from the timing of the subjected reflection light, which is obtained when the sensor 9 moves to pass through one side Ga, and the rotation pulse number of motor 6. Therefore, the shift can be detected by comparing with the timing when held at the normal position of small pliers 43.

A detector detects gamma-rays emitted from inside an imaging region. An acquisition unit acquires a plurality of first projection data sets associated with a plurality of projection angles via the detector. An attenuation-correction unit attenuation-correct the plurality of first projection data sets based on a first CT image associated with the imaging region to generate a plurality of second projection data sets associated with the plurality of projection angles. An index calculation unit calculates an index based on the plurality of second projection data sets. The index is corresponding to a degree of positional offset between the imaging region at the time of acquisition of a plurality of third projection data sets associated with the first CT image and the imaging region at the time of acquisition of the plurality of first projection data sets.

This invention realizes accurate positional offset correction between a plurality of tomograms captured by using a tomography apparatus. The invention is a tomography apparatus which corrects the positional offsets between a plurality of two-dimensional tomograms constituting a three-dimensional tomogram. This apparatus includes a tomogram analysis unit (120) which extracts feature amounts representing the tissue of a measurement target, a tomogram selection unit (140) which selects a standard two-dimensional tomogram from the plurality of two-dimensional tomograms based on the feature amounts, and a tomogram position correction unit (150) which calculates the positional offset amount between the nth two-dimensional tomogram adjacent to the standard two-dimensional tomogram and the (n−1)th two-dimensional tomogram.

Provided is a projection type display apparatus in which an inclination and a positional deviation of optical axes among a plurality of light sources can be easily corrected to obtain a high quality projection image. The green, blue and red laser beams emitted from light sources (1a, 1b, 1c) are converted to parallel beams by condenser lenses (2a, 2b, 2c), and the positions and angles of the optical axes of the beams of the three colors are evaluated by a position detection image pickup means (7a) and an angle detection image pickup means (7b), respectively. The positions and angles of the light sources are adjusted by respective actuators (4a, 4b, 4c) so that the positions and angles of the optical axes are identical. Consequently, the laser beams emitted from the light sources (1a, 1b, 1c) can be combined with high accuracy to thereby realize a high definition projection type display apparatus.

The invention discloses a process for integrally elevating the rooms of a low-course building. Wherein, the quantity, interval and locations of the lifting supports are determined depending upon the load pressure of the part to be elevated; an integral gird is formed by solidifying the truss on the surrounding wall along a reference line; holes are dug at certain interval under the integral gird, two lifting supports are arranged in each hole; the wall reserved under the integral gird is cut open by a cutter, meanwhile the lifting supports are elevated synchronously; after elevating to certain height, the lifting supports are removed in an alternative way in each hole, and the wall is re-built; the upper part of the building is matched with the lower part of the building; the wall is re-built at the location where the removed lifting supports are; expansion concrete is filled full and compact into the gaps between the upper and lower walls, now the elevation of the building is completed. The invention is featured by steady elevation of rooms, is capable for correcting the positional shift of upper and lower wall, and not liable to tilting, etc.
