摘要： PURPOSE: To obtain a method for detecting a gas leaking part of new and existing embedded pipe. CONSTITUTION: A detection pipe 3 filled with liquid is laid along the longitudinal direction of an embedded pipe 2 covered with water closely to the outside thereof. A submersible microphone is inserted into the detection pipe 3 and moved through the detection pipe 3 thus detecting leakage of gas from the embedded pipe 2. Only the specific frequency components (e.g. 1-5kHz) of the sound containing noise caught by the submersible microphone are passed to a signal processor where it is processed to detect gas leakage from the embedded pipe 2.

摘要： PURPOSE:To detect low strain quantity by a method wherein predetermined elongation is preliminarily applied to an optical fiber when the optical fiber is received in a groove in a straightly tensioned state to fix the optical fiber by a resin and the elongation of a spacer is returned to the origin to apply compression strain to the optical fiber. CONSTITUTION:An optical fiber 1 is received in the groove 3 of a space 2 to be fixed to the groove by a resin 4. Elongation of 0.1% is preliminarily applied to the spacer 2 by an appropriate means when the optical fiber 1 is received in the center axis part of the groove 3 in a straightly pulled state and the fiber 1 is fixed in this state by the resin 4 and, thereafter, the elongation of the spacer 2 is returned to 0 to apply compression strain to the strand 1. By this constitution, low strain quantity of 0.1% or less can be detected.

摘要： PURPOSE:To stably and accurately measure landslide for a long time by filling the circumference of a deformation sensor using an optical fiber disposed in a flexible casing tube which is laid under the ground with a filling material having low strength. CONSTITUTION:The casing tube 3 is inserted into an excavated hole 4 which is excavated to the extent of depth which is sufficiently deeper than an expected sliding surface 11 in the ground 10. A material which is easy to be flexed so as to follow the movement of the ground is used for the tube 3. Then, the deformation sensors 1 using the optical fiber are held by spacers 2 which are arranged every prescribed interval and inserted into the tube 3. The spacers 2 can be inserted in the casing tube while they hold the sensors 1 at the prescribed intervals and they are shaped so that the tube 3 is not blocked and the injection of the filling material 5 having low strength is not interfered. Thus, the flexual rigidity of the tube 3 is not raised and the tube 3 is deformed by the movement of the ground caused by the landslide. Besides, the deformation of the tube 3 is propagated to the sensors 1 through the filling material 5.

摘要： PURPOSE:To detect a propulsion tube with high accuracy by moving a transmitter on the ground surface nearly at right angles to the axial direction of the propulsion tube, sending a radio wave to right below and receiving the radio wave signal by a receiver, and measuring the arrival time and level of this radio wave signal. CONSTITUTION:The radio wave signal is sent to right below from the transmitter 3 fitted to a carriage 14 installed on the ground. The receiver 2 is installed on the top of the propulsion tube 1 and the radio wave signal received by the receiver 2 is amplified by an amplifier 12, sent to a signal processor 11 on the ground through a cable run through the propulsion tube 1 and a shaft 7, and displayed on a display device 6. Here, the transmitter 3 sends the impulsive radio wave intermittently while moving nearly at right angles to the axis of the propulsion tube 1. At this time, the value of the movement distance is obtained from the number of turns of the tires of the carriage 14 and sent to the processor 11. The process of transmission and reception is repeated to obtain a measurement result. Thus, the propulsion tube is detected with high accuracy.

摘要： PURPOSE: To economize the supply quantity of fuel by a method wherein temperature detecting terminals are provided at the front, the middle, and the rear of a combustion chamber and changes of temperatures are detected by the change of quality of the produced gas to control the supply of auxiliary fuel.
CONSTITUTION: Temperature detecting terminals 8, 11, 12 are provided at the front, the middle, and the rear in the combustion chamber 3 of the produced gas of a melting furnace, and when the temperature lowers below the predetermined value, the auxiliary fuel control valve 9 operates to supply fuel. After a detecting temperature is restored to the predetermined value, the supply of the auxiliary fuel can be decreased gradually. In this way, calorific value of the heat generated in the combustion chamber is averaged and thermal efficiency can be maintained at a high level. Further, unburnt fuel and smoke are not generated in the combustion chamber, time period for supplying the auxiliary fuel can be shortened and the quantity of supply of the auxiliary fuel can be economized.

摘要： PURPOSE:To apply bending to an optical fiber and stably sense a change in light transmission loss by housing the optical fiber in a metal tube which is continuously bent wavily at constant intervals. CONSTITUTION:A distortion sensor comprises a metal tube 1 which is continuously bent wavily with constant intervals and an optical fiber 2 bent with the same intervals housed in the tube 2 while gaps are filled with resin 3. For example, a stainless steel pipe wherein bend pitch P=6.5mm, full amplitude D1=1.1 mm, outer diameter D2=0.8mm, inner diameter D3=0.5mm and full length 1=50cm is used as the metal tube 1. Although stainless steel is excellent in resistance to weather as the metal tube, a line material which is subjected to groove treatment with an optical fiber housed in the groove may be used. By housing the optical fiber 2 in the metal tube 1 which is bent with constant intervals, the optical fiber 2 is subjected to bending with the constant intervals, so that a change in light transmission loss can be stably sensed.

摘要： PURPOSE:To enable measurement of a size, position and direction of a displacement based on a force working on a subsoil or the like by connecting folded points at both ends of more than two optical fibers with an optical connector to detect an intensity of a back scattering and a Fresnel reflection. CONSTITUTION:Optical fibers 3-6 are arranged concentrically on the outer circumference of a center member 2 and fixed with a protective layer 7. The fibers 3-6 are connected to a series length as a whole with optical connectors 8 and each one end thereof is connected to an optical time domain reflectometer (OTDR) 11. Then, a light pulse from a laser diode 112 of the OTDR 11 is sent to a sensor 1 through a light directive connector 113 and reflected light on the connectors 8 being returned and a back scattered light due to a distortion are branched off by the connector 113 to be detected with an avalanche photodiode 114. Then, a CPU 12 distinguishes the optical fibers by Fresnel reflection points through an A/D converter 116 to determine a vector sum of the intensities of back scattering. This enables continuous measurement of a size, position and direction with one measuring device based on a distortion or the like of the subsoil.

摘要： PURPOSE: To perform the combustion with optimum air fuel ratio and keep the combustion temperature at the set temperature by a method wherein the amount of combustion air is controlled in accordance with the variance of the grade and flow rate of the fuel gas generated from solid waste melting furnace.
CONSTITUTION: Temperature detecting terminals 7, 9 and 10 are provided at the front, middle and rear parts of the combustion chamber 3 for the gas generated from the melting furnace of solid waste such as refuse or the like. When the temperature of the detecting terminal at the front part lowers below the set temperature due to the drop of the calorific value of the generated gas, the amount of air is quickly lowered so as to have the lower limit value determined from the values of air fuel ratio μ of about 0.3W1.5, which are applied to the gas with smaller calorific value, as its lowermost amount. On the contrary, when the temperature of the detecting terminal at the front part exceeds the set temperature due to the rise of the calorific value of the generated gas, the amount of air is slowly increased so as to have the upper limit value detemined from the values of air fuel ratio μ of about 0.8W2.0, which are applied to the gas with larger calorific value, as its uppermost amount. And yet the lower limit value of secondary combustion air is set so as to have the air fuel ratio μ in respect to the total combustion air of 1.1 or more, providing against the sudden rise of the calorific value of the generated gas after the throttling down of the amount of air due to the drop of the calorific value of the generated gas to the lower limit value.
