Abstract: PROBLEM TO BE SOLVED: To reduce the occupying ratio of a characteristic deteriorated section from the side face of a magnetoresistance effect element, which occurs when the element is worked in the entire body of the element and, at the same time, to improve the characteristics of the element by improving the heat radiating characteristic of the element. SOLUTION: A magnetoresistance effect element consists of a laminated film SF, which has a rectangular planar shape having its longer sides (b) in a direction perpendicular to the changing direction of an external magnetic field and the central part of which has a rectangular planar shape (having longer sides (a) and shorter sides (b)), having a shorter sides (c) in a direction perpendicular to the changing direction of the external magnetic field.  The laminated film SF is successively formed by laminating a base film, an antiferromagnetic layer, a magnetization-fixed layer 4 which has an inferior soft magnetic characteristic and an axis of easy magnetization, in parallel with the changing direction of the external magnetic field, a nonmagnetic metal layer, a magnetization-free layer 6 which has a superior soft magnetic characteristic and an axis of easy magnetization which is perpendicular to the changing direction of the external magnetic field upon a substrate 1. In the region where the magnetization-free layer 6 does not exist, a laminated film SF' is formed by successively laminating the layers from the base film to the nonmagnetic metal layer upon the substrate 1 and a magnetic domain control film 9 and electrode layers 10a and 10b are formed on the laminated film SF'.

Title: Seamless pipe wire for submerged arc welding
Inventor: MOTOMATSU RYUICHI
IPC: B23K35/02
Filed: 1992-12-24
Abstract: PURPOSE:To facilitate a welding work of extra thick specific brand steel by specifying the outside and the inside diameters of a hollow seamless wire. CONSTITUTION:In the case of one-layer submerged arc welding of extra thick SM400, SM490 and SM520 steel, a submerged arc welding hollow seamless wire in which the outside diameter D of the wire is 6-10mmphi and the inside diameter (d) is (1/3-2/3)XDmm is used. In this case, when the inside diameter (d) is under (1/3)XDmm, an effect for widening bead width is small. On the other hand, when the inside diameter (d) exceeds (2/3)XDmm, wall thickness becomes small, therefore, in the case its wire is used in a high current, voltage control becomes unstable. Also, the outside diameter D of the wire is <=6mmphi, it is difficult to enlarge an arc and to widen the bead width, and when it exceeds 10mmphi, straightening of the wire cannot be executed enough. In such a way, a welding work becomes satisfactory, and a weld zone in which a welding crack is not generated can be obtained.
