摘要： A method of repairing a pipe at the joint of existing gas pipes, wherein the joint of existing gas pipes is repaired by means of a repairing apparatus to be moved under remote control in the gas pipe, and the repairing apparatus can be put into or taken out of the gas pipe through a working hole formed on the upper part of the gas pipe by drilling means while gas is kept flowing without danger of leakage thereof, whereby the trouble of forming a working hole at the start of repairing operation and restoring the hole to the initial state at the end of the operation can be simplified to reduce time and expense for the repairing operation.

摘要： The present invention intends to provide a solid oxide fuel cell having a supported electrolyte film, which shows sufficiently high reliability, yields a high output, and exhibits high output power density per unit volume. The present invention is characterized by use of a first cermet comprising catalyst and a second solid electrolyte, which has a bending strength of more than 500 MPa and exhibits oxide ion conductivity, for a fuel electrode substrate in an SOFC having a supported electrolyte film equipped with an electrolyte-electrode assembly that is made by bonding the fuel electrode substrate and an air electrode on both sides of an electrolyte film consisting of the first solid electrolyte capable of exhibiting oxide ion conductivity. As a preferred embodiment, stabilized zirconia containing 2 to 4 mol% yttria or 3 to 6 mol% scandia is preferred for the second solid electrolyte.

摘要： A flaw sensor for a metal pipe has an exciting coil for generating remote field eddy currents in the pipe. First and second groups of receiving coils are spaced from the exciting coil by respective distances along the axis of the pipe in a region of the generated remote field eddy currents. The first and second groups have respective pluralities of receiving coils with axes perpendicular to the pipe axis and disposed circumferentially about the pipe axis at predetermined angular increments wherein the receiving coils of the second group are staggered relative to the receiving coils of the first group. A third receiving coil is disposed coaxially with the pipe at still another distance from the exciting coil along the pipe axis but also in the region of the generated remote field eddy currents. When a defect in the thickness of the metal pipe is encountered, a magnetic field caused by the defect to be perpendicular to the axis of the pipe is detected by one or more of the receiving coils of the first and/or second group. The third receiving coil detects phase changes to the magnetic field generated parallel to the pipe by the eddy currents. A ratio of phase changes produced by a standard thickness of a reference pipe and a sample subject pipe is used as a correction factor for detected phase changes in a defective pipe to accurately calculate the defective wall thickness.

摘要： The power generation system includes a reformer and two fuel cell stacks. The reformer and the fuel cell stack are provided in series. Fuel gas produced by the reformer is introduced to a first anode of the first fuel cell stack. Gases discharged from the first anode are directly introduced to a second anode of the second fuel cell stack. Air is introduced to a first cathode of the first fuel cell stack. Gases discharged from the first cathode are cooled by a cooling device and then introduced to a second cathode of the second fuel cell stack. Gases discharged from the second anode and gases discharged from the second cathode are introduced to a heating chamber of the reformer. Gases discharged from the heating chamber are introduced to a steam generator to produce steam used for reformation and then recirculated to the first cathode.

摘要： A hydrocarbon gas to be decomposed, optionally mixed with water vapor, is allowed to flow through the gap between various porous tubes 4 constituting a group of porous tubes provided extending vertically in a decomposition reaction column 1 while air or oxygen is jetted homogeneously from the interior to the exterior of the porous tubes in the direction perpendicular to the stream of the hydrocarbon gas to be decomposed, optionally mixed with water vapor. The mixture is then ignited to form a diffusion flame layer B on the outer surface of the porous tubes 4. With the diffusion flame layer as a heat source, the hydrocarbon gas to be decomposed, optionally mixed with water vapor, undergoes pyrolysis.
