摘要： PROBLEM TO BE SOLVED: To measure the quantity of displacement due to a temperature change in a pipeline arranged in a restricted area, to read out the quantity of displacement at any time, and at the end of measurement, to display the maximum quantity of displacement obtained during the period of the measurement. SOLUTION: A pair of counters M1, M2 are arranged in parallel in a case C. A winding shaft 16 for energizing winding by a spring 18 is supported in the case C. One end of a wire 15a is pulled by a pulley 17 for the winding shaft 16 and the other end is locked to a case wall by a wire end piece 15a. This piece 15a and a pipe P are mutually connected in a tense state by a wire 15. The linear motion of the wire 15 due to the displacement of the pipe P is converted into the rotational motion of the counters M1, M2 through a gearing G. Even when a counter on the market is used for the counter M1 as it is, displacement can be read out at any time. Since a stopper is fixed to a numerical disc with the highest level and rotation only to one direction is allowed in the counter M2, maximum displacement can be displayed.

摘要： PURPOSE:To ensure the safety of piping or equipment, etc., even a function is hindered when a mechanical vibration control apparatus is applied to the piping or equipment, and also install the apparatus, for a seismic support of an internal pump, in a space in the lower part of a nuclear reactor. CONSTITUTION:This apparatus is provided with a compression spring 14, pulling and compressing side spring receivers 20 and 27 for displacing the compression spring 14 to a compressed side when a load is in both the respective cases of pulling and compressing, a piston rod 23 and a load adjusting column 25 for transferring the load to the pulling and compressing side spring receivers 20 and 27, and a case 29 for housing them. A safety device 2, for displacing the compressing spring 14 when the load to the compression spring 14 exceeds a set value in both the respective cases of pulling and compressing, is linked in series to a mechanical vibration proof apparatus 1.

摘要： PURPOSE: To measure three-dimensional displacements of a material to be measured whose displacements are complex, and to input the data into a computer as they are. CONSTITUTION: A rotating body A has U-shaped cross section, and is supported rotatably at a fixed frame body 1 with a vertical axis 2 on the back of it. A rotating body B also has U-shaped cross section, and its both legs are, with a horizontal axis 3, hinged to the both legs of the rotating body A. A receiving tube 5 is, through a bracket, fixed and bonded to the rotating body B, and its center line crosses the axis line of the horizontal axis 3 at right angles. A rod 6 is inserted into the receiving tube 5, and its front end is engaged with a pipeline P, and a rear end is, with a wire 10, engaged with a top of the rotating body B with constant tension. Potentiometers 13, 14 and 15 which measure linear movement of the wire and rotation angles of the horizontal and vertical axes are provided, respectively.

摘要： PURPOSE:To obtain a test equipment which can be mantled/dismantled easily, mounted/demounted easily on/from a mechanical vibration isolator while facilitating transporting and installing works and which can be deformed depending on the installation environment of the mechanical vibration isolator. CONSTITUTION:A first case 2 having a rotary shaft 9 is mounted detachably on the supporting member 32 for a vibration isolator 31. First and second joints 2a, 2b are provided on the opposite ends of the case 2 and a third joint 2c is provided at a position rotated by 90 deg. therefrom. A second case 3 incorporating a motor 14 to be coupled with the rotary shaft 9 is secured detachably to the first and third joints 2a, 2c. A case 4 is secured detachably to the second joint 2b. The case 4 supports a rod 5 having a nut 22 to be screwed over the threaded part of the rotary shaft 9 telescopically. The rod 5 is coupled, at the other end thereof, with a supporting member 33 detachably.

摘要： PURPOSE:To obtain a tester capable of easily attaching to and detaching from a mechanism damper. CONSTITUTION:A motor 8 and a screw rod 9 connected to the motor 8 and a nut 11 screw-filled to the screw rod 9 are slidably penetrating a cover 2a of the case 2 and can be relatively moved in its axial drection. The other end of the slide lever 12 is detachably mounted to one support member 33 of a damper 31 through a pull 14. Both the side faces of a large diameter part 32a with step of the other support member 32 of the damper 31 is tightened with a pair of press plates 5, a bolt 6 and a nut 7 and the case 2 detachably mounted. Test expansion and reduction operation is performed between the support member 32, 33 by clockwise and counterclockwise rotation of a motor 8.
