摘要： A drawing device 4 is mounted in a drawing shaft 3, and pipe replacement device A connected with new pipes is arranged on the side of starting shaft 2, wherein the drawing device 4 and the pipe replacement device A is connected through pull-rods 5 inserted into existing pipes with each other. The pipe replacement device A is comprised of a cutting part 11 including cutter bodies 14 ( shanks 14a to 14i ) arranged in the axial direction and at angular intervals in the circumferential direction, an expanding part 12 having expanding rollers 18a to 18f, and a connecting part 13. Each cutter body 14 has a plurality of cutting edges, wherein distances between the respective cutting edges and the center of the circle become larger in order from the forward side toward the backward side. While the pipe replacement device A is traveled in the inside of cast iron pipes, the inner wall of cast iron pipes is cut by the cutter bodies 14 to form grooves. Splitting of existing pipes into arc-shaped pieces 1a is made starting from the grooves. Arc-shaped pieces 1a are pressed into the ground, by which a tunnel 7 surrounded by arc-shaped pieces 1a and portions of consolidated earth is formed, while new pipes 6 are introduced into the tunnel 7, and besides the new pipes 6 are protected by protective armors formed of arc-shaped pieces 1a.

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 (130) and two fuel cell stacks (I, II). The reformer (130) and the fuel cell stacks (I, II) are provided in series. Fuel gas (FG) produced by the reformer (130) is introduced to a first anode (103) of the first fuel cell stack (I). Gases discharged from the first anode (103) are directly introduced to a second anode (103) of the second fuel cell stack (II). Air is introduced to a first cathode (102) of the first fuel cell stack (I). Gases discharged from the first cathode (102) are cooled by a cooling device (140) and then introduced to a second cathode (102) of the second fuel cell stack (II). Gases discharged from the second anode (103) and gases discharged from the second cathode (102) are introduced to a combustion chamber (130b) of the reformer (130). Gases discharged from the combustion chamber (130b) are introduced to a steam generator (146) to produce steam used for reformation and then recirculated to the first cathode (102).

摘要： A material for a fuel electrode of a solid oxide fuel cell with which volume change of the fuel electrode during performance of oxidation-reduction cycles is reduced as compared to conventional materials. The fuel electrode material includes a powder containing: (a) at least one of nickel and nickel oxide, (b) at least one of titanium oxide (IV) and a titanium source capable of changing into titanium oxide (IV) by heat treatment in air, (c) a solid electrolyte exhibiting oxide ion-conductivity. The fuel electrode material is sintered to prepare the fuel electrode, which is provided for the solid oxide fuel cell. The resulting fuel cell shows a stable power generation even after exposure of the fuel electrode to oxidation-reduction cycles.
