摘要： PURPOSE: To provide an apparatus for measuring a hole bent part, which can measures the deviation of a hole having a large curvature in comparison with the lengths of measuring pipes, from a specified curvature, can be simply used at the measuring spot, and can improve the measuring accuracy. CONSTITUTION: Two measuring pipes 12A and 12B are linked and constituted so that the part between the pipes can be freely bent. To one measuring pipe 12A, a laser-light emitting device 16, wherein an optical axis LR is set in the longitudinal axial-center direction of the measuring pipe 12A, is attached. A laser-light bending device 18 is attached to the front-side position of the laser- light emitting direction of the laser-light emitting device 16. A light-receiving- position detector 20 is attached to the other measuring pipe 12B. A rotary-angle detector 24, which detects the rotary angles around the advancing direction of the measuring pipes, is provided. The linked measuring pipes 12A and 12B are formed into a long pattern in the state, wherein the pipes are inserted in a bent hole 10' in the bent state, so that the effect of the bent state of the hole due to the backlash caused by the gap with respect to the hole 10' on the result of the measurement can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a simple structured measuring system that can measure a target in a widened view field and accurately measure it even if the view field is widened. SOLUTION: This system comprises a pair of rotatably provided wedge prisms 7a, 7b, a pair of motors 8a, 8b for individually rotating these wedge prisms 7a, 7b, and a pair of encoders 9a, 9b for detecting respective rotation angles of the wedge prisms 7a, 7b, and refracts an optical path and measures a target 5. When the combined wedge prisms 7a, 7b is rotated, the optical path is refracted in any direction according to the wedge angles of the wedge prisms 7a, 7b. The refraction angle of this optical path is precisely controlled by operating rotation angles of the wedge prisms 7a, 7b. When the optical path is refracted and the target is measured, a view field is widened and the target can be measured in a simple structure, and the target is accurately measured even if the view field is widened.

摘要： PURPOSE:To cotinuously measure the bending moment of a structure body by a method wherein a running sensor on which a gyroscope has been mounted is run in a measuring tube. CONSTITUTION:A running sensor 18 on which a gyroscope 20 is mounted and which is provided with wheels so as to be easily run inside a measuring tube 16 is suspended by a traction rope 22 from the surface of the ground, and it is run at a proper speed V. Even when the measuring tube 16 and a soil- retaining wall 12 are first buried verically, the measuring tube 16 is bent due to the soil pressure or the like of a side-part mountain 10A. When the running sensor 18 is run in the bent measuring tube 16, the gyroscope 20 inside the running sensor outputs an angular velocity omega according to its bend state and the running speed V. Since the speed V is a speed at which the traction rope 22 is let out, it can be found easily on the basis of the time required and of the let-out length of the traction rope 22. Then, a continuous bending moment which acts on the measuring tube 16 is computed by an arithmetic unit 24 on the basis of the angular velocity omega and the speed V.

摘要： A relative angle detection apparatus requiring only a short time to become active and causing only a small detection error, and a virtual reality providing system adopting the relative angle detection apparatus have been disclosed. The relative angle detection apparatus is a relative angle detection apparatus for detecting a revolution on a plane perpendicular to each axis of an orthogonal coordinate system made by a mounted unit, and includes first to third revolution detecting units each for detecting a revolution about each of the first to third axes of the orthogonal coordinate system serving as axes of revolution. At least one of the first to third revolution detecting units is realized with an optical angle detection unit for detecting an angle of revolution by utilizing polarization. The optical angle detection unit consists of a light source unit separated from the mounted unit, a light-receiving unit united with the mounted unit, and an arithmetic unit. The light source unit irradiates polarized light, of which direction of polarization is confined to a given initial direction, in a direction substantially parallel to an associated axis of revolution. The light-receiving unit includes a polarization filter for receiving light emanating from the light source unit, and a light-receiving device for receiving light emanating from the light source unit and passing through the polarization filter. The arithmetic unit calculates a relative angle of the mounted unit with respect to the given initial direction on the basis of the intensity of a signal output from the light-receiving device.

This is detected to calculate the amount of movement of the light receiving unit 103.
