Abstract: The present invention provides a method of treating rheumatic diseases comprising administering to a patient a pharmaceutically effective amount of a benzamide derivative or salts thereof. The benzamide derivative is a compound represented by the following general formula [1] or a salt thereof as an active ingredient. In the formula, R1, R2 and R3, the same or different, are hydrogen, halogen, hydroxyl, lower alkyl, lower alkoxy, aryl, aryl-lower alkyl, aryloxy, amino, amino-lower alkyl, lower alkylamino or carboxyl, X is aryl or a heterocycle, Y is a direct bond or lower alkylene wherein the lower alkylene can contain oxygen atom(s) in the group, and Z is a direct bond or lower alkylene.

Abstract: A multilayer wiring board assembly component comprises: an insulating substrate component (the insulating resin layer 111); a conductive layer 112 formed on one surface of said insulating substrate component 111 in the form of an electrode pattern; an adhesive layer 113 formed on the other surface of said insulating substrate component 111; and a conductive resin composition 115 with which is filled a through hole passing through said insulating substrate component 111, said adhesive layer and said conductive layer in order to make interlayer interconnection. The bore diameter of the conductive layer portion 114b of the through hole 114 is smaller than the bore diameter of the insulating resin layer portion and the adhesive layer portion 114a to establish electrical connection between the conductive resin composition 115 and the conductive layer 112 by the rare surface 112a of the conductive layer 112.

Abstract: A compound of the formula [I]. ##STR1## The compounds of this invention has excellent thymulin-line activities and expected to be useful for treatment of various diseases such as immunodeficiency and autoimmune diseases.

Abstract: In a method and a device for treating a machined surface of a workpiece made of a brittle material, a laser beam generated by a laser oscillator is applied to the machined surface of the workpiece while the workpiece is relatively moved with respect to the laser beam. Additiives and impurities exsisting in cracks generated on the machined surface melt due to thermal energy of the laser beam thereby to eliminate the cracks and improve the strength of the workpiece.

Abstract: A urethane composition comprising as a base compound a polyol and/or an isocyanate-reactive tar, and as a curing agent a liquid product of a toluene diisocyanate tar occurring as a by-product in the preparation of toluene diisocyanate obtained by dissolving or dispersing the toluene diisocyanate tar in an aromatic solvent having a boiling point at atmospheric pressure of at least 200.degree. C and a method for producing the liquid toluene diisocyanate tar product.

Abstract: A tar-urethane composition comprising (1) an isocyanate-reactive tar obtained by reacting a tar produced as a by-product in the phenol synthesis via hydroperoxides with a formaldehyde in the presence of a basic catalyst and in the presence or absence of at least one phenol compound and (2) a polyisocyanate, which is useful as coating agents, materials for pavement, floor linings, sealing materials and the like.
