摘要:
A gas turbine includes a rotor rotated by combustion gas produced by a combustor that burns fuel, and a casing that is formed by connecting a plurality of casing members divided in plurality, the casing storing the rotor in an inside thereof, and including a second upper-side second vertical inner flange and a third upper-side first vertical inner flange for connecting a second upper casing member with a third upper casing member different from the second upper casing member among the casing members at the inside.
摘要:
An ammonia gas to be determined, and an oxidative gas containing nitrogen oxides in moles more than those of the ammonia are brought into contact with an analytical catalyst capable of forming nitrogen and water from ammonia and nitrogen oxides.Concentrations of nitrogen oxides of the gas before and after the contact with the analytical catalyst are determined, and an ammonia concentration of the gas is determined by converting the difference between the concentrations of nitrogen oxides to the ammonia concentration by calculation.

A gas turbine includes a combustor chamber that houses a combustor unit configured to include a combustor that burns fuel to generate combustion gas for rotating a rotor, a turbine unit chamber that houses a turbine-unit rotor blade and a disk that rotate upon reception of the combustion gas, a combustor casing that forms the combustor chamber, and a casing that is configured to include the combustor casing in which a divided portion on a surface orthogonal to a rotation axis of the rotor is not formed in the combustor casing, but is formed in a portion on a downstream side of flow of the combustion gas lower than the combustor casing.

Coins in an escrow unit and a holding and feeding unit can be collectively returned without increasing the size of a coin processing unit. Stopping positions of the escrow unit are set to an escrow position “a” where the coins sent from the transport path are received, an ejection position “b” where the coins dropped and released from the holding and feeding unit are received, a returning position “c” where the escrowed coins are dropped to a returning box, and a storing position “d” where the escrowed coins are dropped to the coin cassette. The escrow unit is moved to the ejection position “b”, then the escrow unit is moved to the returning position “c”. Thus, return of coins in the holding and feeding unit can be carried out immediately.
摘要:
In a fuel cell comprising a pair of counterposed gas-diffusible electrodes, an electrolyte-retaining, porous matrix provided between and in contact with the electrodes, a fuel chamber for feeding a gaseous fuel to the anode of the pair of the electrodes and an oxidizing agent chamber for feeding a gaseous oxidizing agent to the cathode of the pair of the electrodes, the cell performance is remarkably prevented from lowering by making the electrolyte saturated absorption amount of the cathode smaller than that of the anode, thereby preventing migration of the electrolyte in the electrolyte-retaining matrix.

摘要:
Hydrocarbon oil containing sulfur compounds, for example, lighter petroleum fraction having a boiling point of not higher than 250.degree. C. is hydrodesulfurized to less than 1 ppm with a hydrogenating gas containing 1 to 40% by volume of oxides of carbon (CO.sub.2 and CO) in the presence of a catalyst comprising 3 to 40% by weight of at least one of molybdenum and tungsten, and 2 to 15% by weight of at least one of nickel and cobalt, the balance being titanium oxide. Product gas from steam reforming can be used as the hydrogenating gas.
摘要:
In an apparatus for treating an exhaust gas from a nuclear plant which comprises a container and a cryogenic distillation apparatus disposed in the container for liquefying and separating a radioactive gas therefrom, an adsorbent such as an active carbon is filled in the container to surround the cryogenic distillation apparatus whereby leakage of the radioactive gas on the occasion of an accident can be removed.
摘要:
A magnetic core having a low core loss and having stable characteristics in a low magnetic permeability region can be obtained at a high yield by applying a heat treatment to a magnetic core main body obtained by winding or laminating a ferrous amorphous ribbon In a wet atmosphere containing a limited amount of steam. Further, a magnetic core having stable characteristics for the quality of products can always be obtained at a high yield even when magnetic ribbons as the blank have scattering, by adopting a method of applying a heat treatment to the magnetic core main body as described above by measuring the curie point, the differentiated crystallization temperature or the crystallization temperature of optionally sampled amorphous ribbons and comparing the measured value for the temperature with the curie point corresponding to the heat treatment temperature for the previously prepared aimed magnetic permeability, the differentiated crystallization temperature or the crystallization peak temperature, thereby determining an optimum value for the heat treatment temperature.
