摘要： PROBLEM TO BE SOLVED: To prevent the crush of a sealing member when a weight or a bias load in propulsion is worked, and prevent the penetration of sand and earth or mud. SOLUTION: An outer cylinder 21 and an inner cylinder 22 are assembled together in such a manner as to be slidable by a middle push jack to form a middle push propeller 20, and the middle push propeller 20 is connected between propulsive pipes. A plurality of projection parts 41, 42 are formed in opposed parts of the outer cylinder 21 and the inner cylinder 22, and a seal member 50 is fitted between the projection parts 41, 42. Even when a bias load is worked, the projection part prevents the crush of the seal member 50. A lubricant is pressed into a press-in space 43 between the seal members 50 to prevent the wear of the projection parts 41, 42 and the seal member 50.

摘要： PURPOSE:To make possible to predict the degree of damage of abnormal machine or future spread of abnormality by displaying information relevant to the abnormal point, cause of abnormality or spread of abnormality, in visually arranged form, on a screen. CONSTITUTION:Upon detection of an abnormality in a mechanism section of a gas circuit breaker filled with gas, designated data such as the abnormal circuit breaker, cause and spread of abnormality and a level indicating the possibility of spread are transmitted to a display. Corresponding image data are then read out from an image memory under control of a display control section and displayed on the screen of the display in the form of a fault spread flow chart. An arrow part connecting between the cause of abnormality corresponding to the point of abnormality, i.e., 'lock.increase of friction', and the abnormality spread mode, i.e., 'decrease of switching speed and increase of switching time', is displayed with yellow color so that it can be discriminated from other parts.
