IPC: H01F10/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To detect the direction and the strength of an external magnetic field by a small number of sensor elements by arranging the magnetizing direction of bias layer parts antiparallel to each other, providing at least one pair of sensor elements which fix the reference line, and at least another one sensor element whose magnetizing direction of the bias layer part is arranged at a prescribed angle to the reference line. SOLUTION: The magnetizing directions m3' and m4' of the bias layer part of sensor elements S3 and S4 are permitted to have a discretionary angle (≠0 deg. and ≠180 deg.) to the reference line b, which is decided by the magnetizing directions m1 and m2 of the bias layer parts of other sensor elements S1 and S2. When a current I is permitted to flow through a bridge, at connecting points A1 and measuring points P1 and P2, voltages U1, U2 and U3 related to the angle α of an external magnetic field H compared with the reference line b are obtained. Thus, only the minimum number of sensor elements are required, and the dimensions of the sensor device can be relatively reduced.

Abstract: PURPOSE: To form narrow track type magnetic head cores to such a high quality in which crosstalks are less and chipping does not occur by applying track width forming working to a pair of core material blocks before forming core gaps.  
     CONSTITUTION: Grooves 15, 16 having raised parts 13, 14 of a width equal to track width are formed by grinding to the gap forming faces of a first core material block 26 and a second core material block 27. Next, while observing with a microscope so as to let the positions of the raised parts 13, 14 coincide, the blocks 26, 27 which have been deposited with a slight amount of sufficiently finely selected alumina powder 18 near the gap forming face of one of block in such a manner that the central value of the core gap width tolerances becomes the central value of particle size distribution, are butted together and are fixed by means of a bonding agent. The contact points 19 with the alumina powder of rather larger particle sizes produce core material block spacings 17 close to the central value of the particle size distribution because the core material block faces recess through plastic deformation. Next, glass material is melted into the clearance of the gaps.

Abstract: PURPOSE:To restrain the generation of failures due to the repetition of drive-in diffusion, and realize cost reduction by utilizing the fact that the diffusion coefficient of boron is larger than that of phosphorus in an oxygen atmosphere at a temperature lower than 1050 deg.C. CONSTITUTION:From one main surface of a semiconductor substrate 1, boron 2 and phosphorus 3 are ion-implanted, and then a pn junction having an n-layer 12 is formed on the main surface of the substrate 1, by one time drive-in diffusion in an oxygen atmosphere at a temperature lower than 1050 deg.C. ID an atmosphere of oxygen, the diffusion coefficient of boron 2 is larger than that of phosphorus 3 at a temperature lower than 1050 deg.C. As a result, at the time of drive-in; the diffusion depth of phosphorus 3 becomes shallower than that of boron 2, by superposed ion-implantation of born 2 and phosphorus 3, so that a pn junction, in which an n-layer 12 exists on the surface side, is formed in parallel to the surface. Thereby, the generation of failures due to the repetition of drive-in diffusion is restrained, and cost reduction is enabled.
