Title: Production of hic resistant steel
Inventor: NUMATA MITSUHIRO
IPC: C21C7/04
Filed: 1994-08-11
Abstract: PURPOSE:To produce a steel remarkably improved in HIC resistance, at the time of adding Ca-contg. substance to molten steel, by controlling the adding rate of Ca in Ca-contg. substance to be added by a specified inequality. CONSTITUTION:Ca-contg. substance (such as CaSi) is added to molten steel subjected to deoxidizing treatment by using metallic Al to change Al2O3 in the steel into CaO-Al2O3 inclusions. At this time, the adding rate of Ca to be added in the Ca-contg. substance (expressed in terms of Ca pure content) V (g/T/mim) is controlled by the inequality of 15<=V<=- -8.4X[S]-0.3Xa0+355.8 [where [S] denotes the S concn. (ppm) in the molten steel and a0 denotes the activity oxygen value (ppm)]. Thus, the formation of CaS and CaO inclusions and CaO-Al2O3 inclusions having a high m.p. compsn. is suppressed, and the inclusions are effectively changed into CaO-Al2O3 globular inclusions to remarkably improve the HIC resistance (hydrogen induced cracking resistance) of the steel.

Title: Mr-type magnetic head and its manufacture
Inventor: TACHIKAWA KAZUHIKO
IPC: G11B5/31
Filed: 1994-07-22
Abstract: PURPOSE:To obtain an MR-type magnetic head in which a bonding area between an MR layer and a lead layer can be correctly formed (as designed), and accordingly a sense area can be accurately determined, thereby stable characteristics without variations are obtained. CONSTITUTION:An MR layer 11 of a predetermined shape is arranged on a substrate 10 formed out of ferrite or the like. A predetermined number of sheets of a predetermined MR material are layered to form the MR layer. An insulating layer 15 is disposed on the MR layer. Side faces of t,he layers form a continuous inclined surface (inclining angle theta). A lead layer 16 is set at a predetermined position on the substrate to be bonded with the side faces of the MR layer and the insulating layer. Consequently, the upper end of an actual bonding surface there the power is supplied and signals are detected becomes the boundary S of the MR layer and tone insulating layer. Even when a position of a front end A of the lead layer is changed, a position of the upper end of the actual bonding surface, i.e., S is const,ant. Accordingly, a sense area is not changed, too.
