摘要： In conjunction with the manufacture of a multilayer ceramic capacitor having nickel-containing internal electrodes involving a polishing step for exposing the end of the internal electrodes, a non-reducible dielectric ceramic material is prepared, for the purpose of preventing the polishing step from being prolonged, by furnishing a calcined material containing a compound oxide represented by the formula (I): [(CaxSr1−x)O]m[(TiyZr1−y)O2] wherein 0≦x≦1, 0≦y≦0.10, and 0.75≦m≦1.04, as a main component, adding 0.001-10 mol % based on the main component of MgO or rare earth oxide and firing the mixture. The ceramic material contains predetermined amounts of SiO2 and BaO and/or CaO, and MnO as auxiliary components.

摘要： Objects of the present invention are: to obtain a polyimide that is excellent in heat resistance, transparency, and optical isotropy and is soluble in an organic solvent; to provide, by using either a polyimide or a polyamic acid which is a precursor or the polyimide, a product or a member that is highly required to have heat resistance and transparency; and particularly to provide a product and a member both of which are obtained by applying a polyamic acid solution and a polyimide solution of the present invention to the surface of an inorganic substance such as glass, metal, metal oxide, or a single crystal silicon. These objects can be attained by a polyimide acid and a polyimide which are each prepared from an alicyclic tetracarboxylic dianhydride and a monomer having a fluorene structure.

摘要： The invention is a magnetic recording medium which is effectively protected against forgery by the alteration of recorded data, and a method for carrying out writing and reading on this magnetic recording medium. The magnetic recording medium of the invention comprises a recording material composed of a crystalline alloy containing Fe and Al . In the recoding material, the total amount of Fe and Al is at least 90 at % and the atomic ratio Al/(Fe+Al) ranges from 0.30 to 0.45. The recording material changes from a disordered phase to an ordered phase by heating. The recording material has a saturation magnetization of at least 45 emu/g prior to heating and lowers its saturation magnetization by at least 35 emu/g upon heating. Dark regions are observable in a bright-field image of the recording material by transmission electron microscopy, the dark regions accounting for 15-60% of the recording material in areal ratio and having a maximum breadth of 10-200 nm.
