SOLUTION: A plurality of repairing plans are inputted to a reliability analysis calculation system 14. One of the inputted repairing plans is selected and a facility constitution satisfying a facility condition, a facility system configuration and a demanded gas sending amount at this time is set by referring to information from a control calculation system 12. For the set facility constitution, a fall-tree is made and based on this fall-tree, the scale of the reliability of the entire facilities is calculated. A repairing plan for making a most reliable facility constitution is extracted and outputted and a facility constitution corresponding to this repairing plan is set in the control calculation system 12.

摘要： PROBLEM TO BE SOLVED: To reduce the amt. of water sprayed in an LNG vaporizer to thereby reduce the power cost of a seawater pump. SOLUTION: In the method for running a seawater pump 8 by calculating the amt. of seawater supplied by the pump 8 by using the higher value of the two amts. of water: the necessary amt. of sprayed water obtd. by comparing the temp. of seawater at the entry side of an LNG evaporator 1 to be monitored with the designed conditions of the evaporator 1 and the amt. of sprayed water at the film-breaking limit, as the set amt. of sprayed water, the temps. of sprayed water at tubes 4 near the lower header part 3 of the panel 5 of the evaporator 1 are measured along the right-and-left direction to calculate the difference between each of the above-obtd. temps. and the temp. of seawater at the entry sides of each of the tubes 4; then the apparent amt. of sprayed water is calculated about each tube from the above-obtd. temp. difference, the flow rate of the LNG, the enthalpies of the entry-side LNG and the exit-side gas, and the specific heat of water sprayed; and the amt. of seawater supplied by the pump 8 is increased when the apparent amt. of sprayed water becomes lower than the above set amt.

摘要： PURPOSE:To earth a mobile explosion-proof equipment made up such that it can move with wheels running along a guideway without using a ground wire. CONSTITUTION:An explosion-proof equipment 1 is earthed to a guideway 2 through at least one earth wheel 4 made up by installing a conductive elastic part 6 at a peripheral portion. Any ground wire is therefore unnecessary so that the moving distance of the explosion-proof equipment is never limited by the ground wire. Moreover, the earth wheel 4 makes the peripheral conductive elastic portion to be elastically deformed and resultantly, the peripheral conductive elastic portion is made to facially contact with the guideway, so that it is possible to always accurately make grounding with a low contact resistance and also no sliding material is required; therefore, the earth wheel 4 does not become a resistance at the time of movement or is never worn. More accurate grounding can be realized by applying conductive grease to the surface of the guideway.

摘要： PROBLEM TO BE SOLVED: To provide a property change estimating method in a conduit used in a case where a gas transporting conduit is used in transporting a plurality of kinds of gases having different components, capable of easily determining a diffusing constant, time, and costs for estimating. SOLUTION: The property change estimating method is provided for estimating the behavior of the property change of gas flowing in the gas conduit when the mixture ratio of different types of gases flowing in the gas conduit is changed. Based on the kinematic viscosity coefficient, gas flow rate, and the inner diameter of the conduit of each gas, it is determined in which of a laminar flow region, a turbulent flow region, or a transient region between the two regions the flow in the gas conduit belongs. The diffusion constant used for a diffusion equation is decided by using an equation prepared for the determined region out of predetermined equations different from each other prepared for each of the laminar flow region, the turbulent flow region, and the transient region.

摘要： PROBLEM TO BE SOLVED: To enable the distinction of abnormalities in water spraying in an LNG evaporator. SOLUTION: The causes of abnormalities in water spraying in an LNG evaporator is distinguished as follows: the temp. of seawater at the entry side of an LNG evaporator to be monitored is measured; the temp. of sprayed water at the tubes 4 near the lower header 9 of the panel of the evaporator is measured along the right-and-left direction to calculate the difference between the temp. of seawater at the entry side and the temp. of the sprayed water as to each of the tubes; the apparent amt. of water sprayed is calculated from the above-obtd. temp. difference, the flow rate of an LNG, the enthalpies of the entry-side LNG and the exit-side gas, and the specific heat of the water sprayed; the picture of the surfaces of tubes near the lower header of the panel of the evaporator is taken with a camera 10 to collect dynamic images of water flowing down; the flow rate of water is calculated by extracting the motion vector of a localized notice zone from adjacent frames in the dynamic images; the true amt. of water sprayed as to each tube is calculated from the above-obtd. flow rate by using the known correlation of flow rate and amt. of flow; the abnormalities of water spray is detected as to each tube from the apparent amt. of water sprayed; and the causes of the abnormalities are determined by comparing the apparent amt. with the true amt. of water sprayed.

摘要： PURPOSE: To require no complex control by heating a blackbody panel up to a specified temperature so as to make a specified band of wavelength components of a radiated infrared ray transmit. CONSTITUTION: An infrared ray transmitting glass 2 is fitted on the front face of a box case 1 made of stainless, an infrared ray transmitting glass 3, a blackbody panel 4 for infrared ray radiation, and an electrical heater 5 are fitted thereafter, and the periphery of the panel 4 and the heater 5 and surrounded by adiabatic material 6 so as to constitute an infrared ray radiation panel assembly. The infrared ray transmitting glasses 2, 3 constitute the 3.3mm band infrared ray radiation panel assembly. When the heater 5 is energized so as to heat the panel 4 up to 440 through 450K (about 170 deg.C), only about 3.0 through 3.8μm components out of radiated ray from the panel 4 transmit the glass 3. Next, only about 3.0 through 3.6μm wavelength components transmit the glass 2, and other wavelength components are sharply cut off. The 3.3μm band infrared ray has quite a large absorption coefficient against a CH radical, and can be used for detecting hydrocarbon gas containing the CH group.

摘要： PURPOSE:To obtain a protective glass which ensures the sufficient transmissivity of infrared rays and whose strength can satisfy the condition an explosionproof regulation by a method wherein a sapphire glass within a specific thickness is pasted on, and bonded to, the front of a silicon glass. CONSTITUTION:A protective glass 1 is fixed to the front of an explosionproof case 5 by means of a mounting utensil 6. The protective glass 1 is a circular glass in which a silicon glass 2 and a sapphire glass 4 on its front have been pasted. The silicon glass 2 is a single crystal of Si, and an antireflection coating film 8 is vapor-deposited on a pasting face to the sapphire glass 4. The sapphire glass 4 is a UV-grade sapphire, for infrared transmission of Al2O3, and its thickness is within 5mm. The sapphire glass 4 is pasted constantly on the silicon glass 2 by an adhesive. An adhesive which is based on an acrylic or the like is used as the adhesive, it is composed of a photoreactive resin which is hardened when it is irradiated with ultraviolet rays, and its thickness is made sufficiently thin so as no to affect the transmission of infrared rays.
