    摘要： A method for manufacturing a high alloy pipe comprises hot working, a high alloy material pipe having controlled amounts of C, Si, Mn, P, S, Ni, Cr, Mo, Cu, Al, N, O, and optionally Ca, Mg, and rare earth elements, with the balance Fe. The pipe composition satisfies the formula N×O≦0.001. The pipe is subjected to cold working to form the high alloy pipe, wherein the final cold working process is performed under the condition that a working ratio Rd in the reduction of area satisfies 15≦Rd (%)≦370×(C+N), where N, O and C are the contents (by mass percent) of the respective elements, and Rd is the working ratio (%) in the reduction of area. The pipe has an excellent ductility and an excellent corrosion resistance when cold working is performed to obtain a high strength after pipe-making.

    摘要： An image forming device comprises a tray parameter table in which tray IDs for identifying one or trays of the image forming device and tray parameters for the respective tray IDs are stored in a mutually associated manner. A replacing unit receives an input tray ID and an input tray change parameter specified by an externally supplied printer control protocol, and replaces a tray parameter contained in the tray parameter table and corresponding to a tray ID which is the same as the input tray ID, by the input tray change parameter.
