Title: Composite type magnetic head
Inventor: TOMITANI TADASHI
IPC: G11B5/133
Filed: 1987-04-06
Abstract: PURPOSE:To obtain a composite type magnetic head adequate for a high coercive force recording medium by using ferrite having a coefft. of thermal expansion equivalent to 125-145X10<-7>/ deg.C coefft. of thermal expansion of a thin magnetic film material having the saturation magnetic flux density larger than the saturation magnetic flux density of ferrite as a magnetic core. CONSTITUTION:The coefft. of thermal expansion of the ferrite is specified to 125-145X10<-7>/ deg.C. The main compsn. of the ferrite is confined within the range enclosed by AB, BC, CD, and DA connecting the respective points A(25, 16, 59), B(25, 11, 64), C(15, 14, 71), and D(15, 19, 66) expressed in molar % of at least (MnO, ZnO, and Fe2O3). The region shown by diagonal lines in the characteristic chart indicating the relations between the compsn. of the Mn-Zn ferrite and the coefft. of thermal expansion is an adequate region. Generation of exfoliation between the thin magnetic film and the ferrite, cracks, etc., is thereby prevented in the production process for the composite type magnetic head and, therefore, the stable production of the composite type magnetic head is permitted.

Thus the BOD contained in a liquid is decomposed and removed as soon as possible under the aerobic conditions. At the same time, the SS is also removed effectively by the organism filtering function of the filter material. In this case, the BOD must be removed so as to set the BOD/COD ratio at ≤0.5. Then the secondary treated water with which the first treating process is put under the next adsorbing process to be completely mixed with a fluid medium composed of the glanular active carbon and/or zeolite, etc. and with the introduction of the air. After this process, the water is separated from the fluid medium. In such way, the COD can be effectively eliminated with a low cost.

IPC: B21B1/38
Filed: 1985-04-20
Abstract: PURPOSE:To make possible the cross rolling down of a steel ingot by inclining at least the rolls of the foremost stage out of vertical rolls disposed in the rolling direction in the direction opposite from the advancing direction, executing rolling while biting the rolling material to the rolls and decreasing the angle of inclination of the rolls. CONSTITUTION:A pair of the vertical rolls 1 of the fore stage are preliminarily inclined at a suitable angle with the vertical line in such a manner that the upper part thereof points the direction opposite from the progressing direction within the plane parallel with the advancing direction of the rolling material S. The angle of inclination of the vertical rolls in the middle stage is made smaller than than the angle of inclination of the vertical rolls in the front stage. The projecting curving deformation in the transverse direction generated at the front end of the material S can be transmitted to the rear of the rolling material by the inclined vertical rolls 1 of the front stage and therefore the angle of inclination of the front stage rolls is decreased during the progression of rolling. The cross rolling reduction is considerably increased by executing rolling in the above-mentioned manner, by which the cross rolling down of the steel ingot is made possible and the yield of the product is improved.
