Abstract: An adjustment device of a punching device punches a workpiece on a die so that the workpiece is punched into a predetermined shape. The adjustment device includes a first drive mechanism that moves the punch or the die in a direction orthogonal to a punching direction, and a controller connected to the first drive mechanism. The controller brings the punch and the die into contact with each other by moving the punch or the die in four orthogonal directions in a plane perpendicular to the punching direction from an initial position where the punch is inserted into the punching die. The controller causes the first drive mechanism to move the punch or the die to a center position where a central axis of the punch and a central axis of the die are aligned with other.

Abstract: Provided is an adjustment device of a punching device which punches a workpiece placed on a die having a punching die with a punch so that the workpiece is punched into a predetermined shape. The adjustment device of the punching device includes a first drive mechanism that moves the punch or the die in a direction orthogonal to a punching direction, and a controller connected to the first drive mechanism in a communicable manner. The controller brings the punch and the die into contact with each other by moving the punch or the die in four orthogonal directions in a plane perpendicular to the punching direction from an initial position where the punch is inserted into the punching die. Based on a distance between the initial position and each contact position in the four directions, the controller causes the first drive mechanism to move the punch or the die to a center position where a central axis of the punch and a central axis of the die are aligned with other.

Abstract: A pyrochlore-type oxide represented by a general formula A2B2O7-Z is prepared by precipitate formation, where A and B each represent a metal element, where Z represents a number of at least 0 and at most 1, where A contains at least one element selected from a group consisting of Pb, Sn, and Zn, and where B contains at least one element selected from a group consisting of Ru, W, Mo, Ir, Rh, Mn, Cr, and Re. Impurities are then sufficiently removed through washing and drying processes, and the pyrochlore-type oxide is calcined under controlled conditions. This allows the crystallinity of the pyrochlore-type oxide, which contained amorphous parts immediately after the production of the precipitate, to be increased so that the resistance to acid can be improved while preventing particle aggregation.
