    摘要: A method for producing iron carbide by bringing iron ore into contact with a reducing gas containing hydrogen and a carbon compound at a specified reaction temperature to reduce and carburize the iron ore with the participation of a sulfur component, the method includes measuring the reaction temperature, partial pressure P(H.sub.2) of the hydrogen and partial pressure P(H.sub.2 S) of hydrogen sulfide contained in the reducing gas, calculating sulfur activity as in the reducing gas from equation (1) shown below, and adjusting the partial pressure P(H.sub.2 S) of the hydrogen sulfide in the reducing gas to obtain as=1.0 to 2.0. at reaction temperatures of 550.degree. C. and above but less than 650.degree. C., as=0.7 to 2.0 at 650.degree. C., and as=0.05 to 1.0 at over 650.degree. C. and up to 950.degree. C.: as=(P(H.sub.2 S)/P(H.sub.2))/(P(H.sub.2 S)/P(H.sub.2))E (1) where (P(H.sub.2 S)/P(H.sub.2)) represents the ratio between the partial pressures of H.sub.2 S and H.sub.2 in the reducing gas and (P(H.sub.2 S)/p(H.sub.2))s is the ratio between the partial pressures of H.sub.2 S and H.sub.2 in a condition where the reaction of equation (2) below is in equilibrium: FeS(s)+H.sub.2 (g)=Fe(s)+H.sub.2 S(g) (2) where (s) and (g) represent solid and gaseous phases, respectively.

    摘要: In a method for heat treatment of an existing pipe constituting a piping system, for converting the residual stress at a welded metallic portion and a welding heat influenced portion of the inside surface of the pipe, into a compressive stress and thereby generate the compressive stress in the inside surface of the existing pipe, a coolant is retained in the pipe; an arbitrary portion of the outside surface of the pipe is heated; thereby a temperature distribution little in temperature difference is produced in the wall surface of the pipe at the heated portion; and then the coolant is allowed to flow. By converting the residual stress at the welded metallic portion and the welding heat influenced portion of the inside surface of the pipe, into the compressive stress, stress corrosion cracking generated from the welded metallic portion and the welding heat influenced portion can be suppressed.

    摘要: A paper refeeding device incorporated in an image forming apparatus for temporarily stacking paper sheets each coming out of an image forming section and carrying an image on one side on a refeed tray and, then, refeeding the paper sheets to the image forming section. An air velocity switching mechanism causes an air knife to blow air at a breeze velocity or a zero velocity which does not lift the paper sheets stacked on the refeed tray, until more than a predetermined number of paper sheets have been discharged by discharge rollers and stacked on the refeed tray.
