The present invention is intended to provide a metal jacket for a cementless artificial joint stem, wherein shear force detrimental to the service life of an artificial joint can be markedly reduced and stress shielding phenomena can also be markedly relieved, due to the construction of the metal jacket which can be fixed to the bone and can enclose the surface of the stem so as to allow for the stem of artificial joint to slide vertically relative to the bone, and wherein osteolysis of a bone due to the infiltration of wear particles can be minimized by curbing the gap formation between the bone and the stem.To that end, there is provided according to the invention, a metal jacket for a cementless artificial joint stem, which jacket is so formed as to enclose at least a part of the cementless artificial joint stem 21, said stem with jacket being inserted longitudinally in the opening formed in the bone canal of a human body, and on the surface of which jacket surface-processed metal layer or metal wires 12 is formed so that the bone can make interlocking with the metal jacket as the bone gets on-growth onto the metal jacket.

A thin film made of a material containing a metal and silicon is formed on a light-transmissive substrate. Then, a treatment is performed to modify a main surface of the thin film in advance so that when exposure light having a wavelength of 200 nm or less is accumulatively irradiated on a thin film pattern of a photomask to be produced by patterning the thin film, the transfer characteristic of the thin film pattern does not change more than a predetermined degree. This treatment is performed by carrying out, for example, a heat treatment in an atmosphere containing oxygen at 450° C. to 900° C.

Disclosed is a combined process for hydrotreating and catalytic cracking of residue, wherein the residue, catalytic cracking heavy cycle oil with acidic solid impurity being removed, optional distillate oil and adistillate of catalytic cracking slurry oil from which the acidic solid impurity is removed are fed into residue hydrotreating unit, the hydrogenated residue obtained and optional vacuum gas oil are fed into catalytic cracking unit to obtain various products; the catalytic cracking heavy cycle oil from which the acidic solid impurity is removed is circulated to the residue hydrotreating unit; the catalytic cracking slurry oil is separated by distilling, the distillate of the catalytic cracking slurry oil after removing off the acidic solid impurity is circulated to the residue hydrotreating unit. This process makes the residue hydrotreating and catalytic cracking being combined together more effectively such that it is not only able to improve product quality of the residue hydrotreating, elongate operation cycle of the residue hydrotreating unit, but also increases the yield of the hydrogenated diesel oil and catalytic cracking light oil, and decreases coking quantity of the catalytic cracking.

An exhaust gas purification catalyst includes: a lower catalyst layer that contains a ceria-zirconia mixed oxide having 50 to 70 mass % of CeO2 and 5 mass % or more of Pr2O3 and carries at least one of Pt and Pd; and an upper catalyst layer that contains at least zirconia and carries at least Rh, wherein the total amount of CeO2 per liter of the carrier base is 15 to 30 g. Because the amount of CeO2 is small, formation of H2S is suppressed and a high capability of adsorbing and releasing oxygen is brought out in spite of the small amount of CeO2.
