Abstract: The present invention provides a method for producing 2-(4-methyl-2-phenylpiperazin-1-yl)pyridine-3-methanol, and this method includes the step of catalytically reducing 2-(4-methyl-2-phenylpiperazin-1-yl)-3-cyanopyridine in the presence of a partially deactivated palladium catalyst in an aqueous acid solution.

Abstract: The invention relates to denture-supporting permanent magnet assemblies each using a magnetic attractive force, and provides denture-supporting permanent magnet assemblies, denture-supporting keepers, and denture-supporting magnetic attachments each of which uses a magnetic material with a high saturation magnetic flux density, i.e., a magnetic material comprising 15.5-18.5 wt % Cr and balance Fe as magnetic materials used for the permanent magnet assembly and the keeper in order to provide a magnetic attachment which keeps an excellent attractive force even if miniaturized.

Abstract: A high melting metal silicide sputtering target which comprises a fine texture whose stoichiometric composition grains of MSi.sub.2, where M represents a high melting metal, have a maximum grain size of 20 .mu.m, whose free silicon grains have a maximum grain size of 50 .mu.m and whose oxygen content is not more than 200 ppm and has a density ratio to the theoretical density of 99% or more has good film characteristics including the reduction in the number of grains formed on the sputtered film and is useful as an electrode material or a wiring material in semi-conductor devices.
