摘要： PROBLEM TO BE SOLVED: To simply evaluate the form of damage in a structural material in a short period of time at a work site. SOLUTION: The surface conditions of a structure are imaged to evaluate the form of a damage. The damage is detected from the imaged surface conditions and a plurality of line segments are extracted from lines constituting the damage. In this event, from among reference gages having a plurality of line segments of different lengths although the ratio of widths to lengths is constant, line segment having suitable line widths are applied to lines found by digitizing an imaged image plane. The form of the damage is evaluated from a relation between the total length of the plurality of extracted line segments or an average damage length and crystal grain size or an average grain boundary length.

摘要： PROBLEM TO BE SOLVED: To reduce the seismic load and improve the earthquake resistance by locating the position of the top of a gap part at lower position within a specific dimension range from the top surface of an internal pump fixing nozzle and shortening the length of a motor casing. SOLUTION: The position of the top 11a' of the gap part 11 between a internal pump fixing nozzle 3 and a motor casing 2 is moved to lower position within the range of 130 to 780mm from the upper surface 3a of the nozzle 3. By moving lower the position of the gap part 11 top 11a' than the previous position in this manner, the length of the motor casing 2 is shortened. Thus, the natural frequency of the motor casing 2 is increased to separate the natural frequency of the motor casing 2 and make the structure capable of reducing seismic load. Also by shortening the motor casing 2, moment arm is reduced and so the moment load caused at nozzle root 2a' in the motor casing 2 side can be reduced.
