摘要： PURPOSE:To measure the displacement of a pipe line highly accurately by coupling a traveling body being hauled by a cable with an inertial sensor through a bendable coupling so that the inertial sensor is not affected in the hauling direction of cable. CONSTITUTION:A bendable rope 22 couples the central part B at the rear end of a body 18 having wheels 20 and running through a pipe line 10 with the central part A at the front end of a casing 14 having wheels 16 and covering an inertial sensor 12. A hauling cable 26, having one end fixed to the front end of the traveling body 18, is wound around a cable winding reel 24 on the outside of outlet 10B of the pipe line 10. Since the sensor 12 is run from an inlet 10A to the vicinity of the outlet 10B in order to calculate the displacement of the pipe line from a reference position at the time of embedment thereof, the cable 26 sags at the time of hauling to exert downward force F1 to the traveling body 18. The traveling body 18 thereby travels while inclining forward but the inclination angle theta1 of the rope 22 with respect to the axis 10c is negligible when compared with the inclination angle theta0 of the cable 26. Consequently, the sensor 12 does not incline but runs along the profile of pipe line and measures the displacement accurately.

摘要： PROBLEM TO BE SOLVED: To perform replacement work for a shutdown rod by one worker easily in a short period of time. SOLUTION: When a cover 108 is closed with a coupling shaft 109 as a center, a lever member 110 pushes the surface of a shutdown rod 105, the tip of the lever member 110 is positioned at the inner portion of a shutdown rod holding base 104 and locked. A rotation by the cover 108 and a force by the rotation around the pressuring shaft 112 of the lever member 110 as a center are applied to the shutdown rod 105 through the lever with the fulcrum at the point where the lever member 110 is locked. When the cover 108 comes to a predetermined position where the shutdown rod holding base 104 is sealed by the cover, a lock portion 114 provided at the other end portion of the cover 108 can be jointed to the other end portion of the shutdown rod holding base 104, and then locking is performed and the shutdown rod holding base 104 is sealed by the cover 108.

摘要： PURPOSE:To shorten preparation time by containing instruments and the like affected by temperature in a container thermally insulating from the surroundings and correcting them. CONSTITUTION:An instrument 1 is contained in a container 4 to thermally insulate from the surroundings 8. Therefore, the heat accompanied only by the operation of the instrument 1 is considered. The instrument 1 before the operation should be at temperature theta0 the same as the surroundings 8, and the instrument after operation start generates heat to raise the temperature. The generated heat is defined as P, the heat capacity of the instrument 1 and its support 2, C and the time, t, then the temperature theta0 rises from the initial temperature theta0 following the equation theta=theta0+(P/C).t. Though the deviation from the equation will increase as the state approaches to the saturation, a certain range can be approximated by the equation. Furthermore, no irregular heat conduction exists on the surface of the instrument, and so a constant relation stands between the measured result of the instrument 1 and the temperature. Thus, exact correction of the measured result with a correction part 6 based on the detected temperature with a temperature detector 5 is possible immediately after the operation starts.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive high speed gate device that an unnecessary vibration is reduced and opening/closed is frequently executed at high speed. SOLUTION: An electronic control type motor-driven machine 107 is controlled by a motor-driven machine controller 117 and rotated when an interruption bar 101 is opened/closed. In a rocking mechanism, an arm fitted to the output end is rotated when the machine 107 is rotated and the rotary movement is converted into a reciprocative movement. The interruption bar 101 opens/ closes a gate in accordance with the reciprocative movement of the rocking mechanism. The controller 117 controls the rotary speed of the machine 107 and controls the rotary speed when the bar 101 is in a semi-opened state to increase the speed at the time of starting and braking.

摘要： PROBLEM TO BE SOLVED: To unnecessitate burying works and to easily install this device by detecting a moving object from a moving image that is photographed with a camera and deciding it as a vehicle when respective values of the size and speed of the object and motion vector are in the range which is preliminarily set. SOLUTION: A television camera 101 which is installed at a parking lot entrance outputs photographed images. A box detecting part 103 detects a box of each image of a frame buffer 102. An area calculating part 104 gets an area from the size of a box that is detected by the part 103. A reference point extracting part 105 extracts one appropriate point of an outline that forms a box that is detected by the part 103 as a reference point. A vector calculating part 106 calculates a motion vector which shows the moving quantity and direction of the same reference point on adjacent frames that are detected. A speed calculating part 107 calculates the speed of a box in an image from the motion vector. When the size and speed of these objects and the motion vector are in the range that is preliminarily defined, it is discriminated as a vehicle.

摘要： PURPOSE:To attain a horizontal state of a platform highly precisely in a short time by a method wherein an output of an accelerometer at the time when a power source is made is detected, a tilt angle of the platform is determined as a computed estimated value by integrating the output, the detection output is lowered by correcting the tilt angle, and the detection output is reduced gradually by repeating this operation. CONSTITUTION:An output thetar of an accelerometer 18 is inputted to integrators 30 and 32. By integrating twice the output thetar of the accelerometer 18 at this time point, a computed value of a tilt angle around a roll axis R of a platform 12 is obtained as an output of the integrator 32. When an estimated value of the tilt angle of the platform 12 is computed by a tilt angle estimating computation means 34, an operation of decreasing the estimated tilt angle is executed by a corrective gyro 14. By repeating this process in a plurality of times, the horizontal plane of the platform 12 can be set as an initial set value. A similar process for setting the initial value of the horizontal plane is repeated also for the tilt angle around a pitch axis and, after all, the platform 12 of an apparatus can be set initially in the state of the horizontal plane in a time shortened sharply.

摘要： PURPOSE:To achieve a minimization of bias variations in a gyroscope, higher linearity and scale factor safety and further an expansion of the maximum detection angular velocity range by making an output signal of the gyroscope exactly proportional to an input rotational angular velocity concerning a signal processor for an optical gyroscope. CONSTITUTION:Frequency components of frequencies fn, 2fn and 4fn of photoelectric conversion output signals 7 are converted into signals of frequencies fn, 2 fn and 4 fn respectively. Moreover, a signal 19 digitized is demodulated digitally with digital signals 24 and 25 synchronized in phase with a phase modulator drive signal 8 and sifted by 90 deg. in phase therefrom to judge the polarity of the rotational angular velocity based on the results. Then, a control is so performed that an amplitude ratio of signal components corresponding to the frequency of 2fn and 4fn of the signal 7 is made fixed thereby outputting a signal 33 proportional to the rotational angular velocity.
