摘要： PROBLEM TO BE SOLVED: To provide a method by which a laminated ceramic sheet can be positioned with high accuracy even when a defective target mark exists and, in addition, the abolition of a laminated ceramic sheet due to a defective target mark can be avoided.
SOLUTION: Master data 51 containing edge length data a-d and interior angle data α-δ of a square obtained by connecting four target marks A-D to each other are prepared. When the acquisition of the coordinate data of the target mark A becomes impossible with respect to a given laminated ceramic sheet 1, the virtual coordinate data (iX1 and iY1) of the target mark A are calculated by applying the master data 51 to the coordinate data (X2, Y2, X4, and Y4) of other target marks B and D. In addition, the position of the laminated ceramic sheet 1 is corrected based on the coordinate data (X2, Y2, X3, Y3, X4, and Y4) of the target marks B-D and the virtual coordinate data (iX1 and iY1) of the target mark A.

摘要： PURPOSE:To facilitate a mounting operation of a coil part by installing a head core and a coil part to be mounted thereon in a slider, exposing the two ends of the head core projecting to both sides of the coil part to the surface of the slider and sticking a magnetic material film to the surface of the slider so as to bestride the two ends of the head. CONSTITUTION:An amorphous ribbon is worked to an L shape as the head core 12 and the coil part 12 is inserted to one side thereof. The outer side of the core 12 is molded of a nonmagnetic molding material 14, such as cement glass and is ground to a prescribed size, by which a slider structural body 16 is obtd. The core end faces on both sides of the coil part 13 are exposed on the surface of the structural body 17 by this facing. A nonmagnetic gap material 17 is then stuck to the rear end face 16c of the structural body 17 and the magnetic material film 18 of 'SENDUST(R)', etc., is stuck by sputtering from the front surface 16a of the slider opposite to the base 16 of the structural body 17 to the rear end face 16c. The top end face 12a of the L-shaped core side part and the magnetic material film 18 are magnetically connected to form a closed magnetic part between the core 12 and the magnetic material film 18 via the magnetic gap.
