摘要:
A welding method for two members adapted to be welded and formed of a low-alloy steel for structural purposes causing the weld metal to develop martensite transformation during cooling after welding, so that the weld metal becomes expanded to a greater degree at room temperature than at a temperature at which the martensite transformation initiates. The welding material comprises a ferrous alloy containing C, Cr, Ni, Si, Mn, Mo and Nb, all of which meet substantially with the contents of the following equation (1): ##EQU1##

摘要:
A pharmaceutical preparation for rectal administration by which a drug is retained in the affected region or the lower region of the rectum, where the drug is sustained-released is disclosed. The present invention is a pharmaceutical preparation for rectal administration comprising a coated drug-supported particle dispersed in a base, wherein the coated drug-supported particle is what a drug-supported porous microparticulate carrier is coated with a water-soluble polymer having a certain viscosity.
