    • This invention provides an electron beam measuring device capable of performing three-dimensional image measurement of a sample with high precision, irrespective of the tilt angle and height of the sample, by adjusting an electron optical system of a scanning charged-particle beam device so as to be suitable for image measurement. The electron beam measuring device includes a measuring section 20 adapted to tilt a reference template held by a sample holder 3 and an irradiated electron beam 7 relative to each other by means of a sample tilting section 5, to find the shape or coordinate values of the reference template based on a stereo image photographed by an electron beam detecting section 4, a calibration data preparing section 30 for comparing the measuring results at the measuring section 20 with known reference data to prepare calibration data for a stereo image photographed by the electron beam measuring device, and a calibration section 40 for performing a calibration based on the calibration data so as to reduce aberration in an image of the sample detected by the electron beam detecting section 4. Based on the stereo image calibrated by the calibration section 40, the shape or coordinate values of the sample 9 are found.

    • A pipe liner bag everting nozzle is provided for allowing an operator to freely access a manhole during a lining operation. A pipe liner bag everting nozzle comprises a guide tube fixing end for fixing one end of a guide tube, and a pipe liner bag fixing end for fixing a folded end of an uneverted pipe liner bag passed through the guide tube, wherein the guide tube fixing end has a diameter smaller than a diameter of the pipe liner bag fixing end. Since a guide tube having a smaller diameter than that of a pipe line to be repaired (or the pipe liner bag) can be used, a sufficient gap is formed between the guide tube and the manhole, thereby allowing the operator to freely access the manhole during the lining operation for inspection and confirmation of a lining situation.
