Abstract: A thiophene derivative containing a phenylamidino group represented by the general formula (I): ##STR1## wherein R.sup.1 and R.sup.2 are the same or different from each other and are hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms or an alkoxyl group having 1 to 4 carbon atoms; or a pharmacologically acceptable salt thereof. The compound is useful for the treatment of inflammatory diseases.

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 method of making a layered electrostrictive displacement device by forming sheets of an electrostrictive material alternately with internal electrodes. The laminate formed therefrom has two opposite surfaces at which the ends of the internal electrodes are exposed and two other opposite surfaces at which alternate layers of the internal electrodes are exposed. Temporary external electrodes are formed on the latter mentioned opposite surfaces. Alternate layers of the exposed portions of the internal electrodes are plated at one surface of the laminate with a metal while using a temporary external electrode as a cathode. The exposed portions of the other internal electrodes are plated with metal using another temporary external electrode as a cathode. The non-plated portions of the plated surface are selectively removed to form recesses, and an insulating film is formed on the recesses.
