摘要： PURPOSE:To provide a city gas pressure regulating device which copes with variation in gas demand in a short time, and which can effectively recover energy. CONSTITUTION:An expansion turbine 13 and bypass governors 14a, 14b, 14c are provided between an intermediate pressure A line 11 and an intermediate pressure B line 12. Gas at a lowest flow rate FG1 which gives a stable operation flows through at least one bypass governor 14a. When the gas flow rate F1 in the intermediate pressure B line 12 is larger than the sum of FG1 and FSET lowest value, the corresponding quantity of city gas is fed into the expansion turbine 13 as an expansion turbine gas flow rate F2 by means of a flow control device 19. In the expansion turbine 13, energy is recovered as a power when the pressure is decreased from the pressure P1 of the intermediate pressure A line 11 to the pressure p2 of the intermediate pressure B line 12 for rotating a generator 20. Further, the city gas can be heated also at the inlet side of the expansion turbine 13 so as to increase the recovery power, and a low temperature heat can be recovered from the city gas which has been cooled, at the outlet side of the expansion turbine 13.

摘要： PURPOSE:To detect the damage of an inner pipe or an outer pipe by providing a sensor part on a void between the inner pipe and the outer pipe, and measuring a temperature distribution of the void between the inner pipe for carrying substance and the outer pipe for protecting the inner pipe. CONSTITUTION:On the outside peripheral surface of an inner pipe 1 through which warm water or cold water for supply is allowed to pass, a heat proof material 3 is provided, and in the space 4 between the heat proof material 3 and an outer pipe 2, an optical fiber cable 5 is provided. This cable 5 becomes a sensor part of a temperature detecting means. That is, a pulse light is made incident from one end of the cable 5, and in a backscattering light emitted from the incident end, by measuring an intensity signal of stokes or antistokes light by Raman scattering, a temperature distribution in the longitudinal direction of the cable 5 can be measured. In such a way, a leakage of warm water or cold water caused by damage of the inner pipe 1, or a water leakage, etc., from the outside caused by damage of the outer pipe 2 can be detected.

摘要： PURPOSE:To suppress a calorific value of mixture gas to a range of a deviation alpha or less from a preset target value by providing a means which opens a second flow rate control valve so that a flow rate is adjusted to the value of the second flow rate control valve responding to that of a first flow rate control valve. CONSTITUTION:When a flow rate F2 of liquefied petroleum gas measured by a flow rate system F2 is a predetermined liquefied petroleum gas flow rate value F20 or less by which maintenance of a flow rate is stabilized, a liquefied natural gas flow rate F1a is determined from a valve control value MV1a by means of flow rate/opening characteristics. F1 is the liquefied natural gas flow rate to determine a target natural gas flow rate F1b=F1a+ F1, and from the flow rate/opening characteristics, a valve opening MV1b responding to liquefied natural gas F1b is determined. A target value F12b of a second flow rate control valve FV2 is determined in a way that a calorific value of liquefied natural gas measured by a liquefied natural gas calorific value measuring means Q4 is Q4, a predetermined calorific value of liquefied natural gas is Q6, a calorific value set value SV5 of a regulator Q1C5 is 11000 kcal/Nm , and from the flow rate/opening characteristics, a valve opening MV2b responding to a liquefied petroleum gas flow rate F2b is determined. When a calorific value of delivery gas is outside a range of 11000+ or -alpha(Kcal/Nm ), the opening of the second flow rate control valve FV2 is regulated by a predetermined value beta to correct the opening.

摘要： PURPOSE:To easily and rapidly perform flaw detection even when a welded line is long and complicated, by parallelly providing three or more of eddy current flaw detection coils to a self-propelling chasis in the lateral direction and performing automatic steering operation on the basis of informations from the coils. CONSTITUTION:A steering apparatus 2 for altering the number of relative rotations of coils 1a, 1b and electromotors M1, M2 separately driven by the electromotors M1, M2 is provided to a chasis 1. Six eddy current flaw detection coils 3a-3f are parallelly provided to the chasis 1 in the lateral direction thereof while a transmitter 4 for informing the informations from the coils, a controller 5 for automatically operating the steering apparatus 2 on the basis of the informations from the coils and a power source 6 are mounted to the chasis 1. The controller 5 detects and judges not only the branching and intersecting of welded line but also the lateral shift of the welded line with the flaw detection apparatus on the basis of the detection of base materials A, B or a welded part c by each coil and automatically controls the steering apparatus 2 so that the flaw detection apparatus runs along the welded line. By this method, the flaw detection can be performed easily and rapidly even with respect to a long and complicated welded part.

摘要： PURPOSE:To prevent an electronic equipment from being excessively cooled by a low-temperature liquified gas, by providing an electric heater for heating a vacuum chamber incorporating the electronic equipment, and connecting with the vacuum chamber a cold finger for liquifying a gas by a cooling liquid stored in a tank. CONSTITUTION:An electronic equipment accommodating box 9, 7d for a body and an inspection sensor is formed such that a heat insulator 16b is lined on the substantially entire surface of a case 16a, and a valved vent pipe 16c and a cold finger 16d are connected to the case 16a to form a vacuum chamber surrounded by the heat insulator 16b. A degree of vacuum in the vacuum chamber is sufficiently maintained by a cooling and condensing operation of a low- temperature liquified gas stored in a tank in the cold finger 16d. Further, an electric heater 16e is provided in the vacuum chamber. Thus, it is possible to prevent the electronic equipment in the vacuum chamber from failing owing to the low-temperature liquified gas by the heat insulation and the heating.
