Title: Method for desulfurizing molten iron
Inventor: KIKUCHI NAOKI
IPC: C21C1/02
Filed: 1995-06-30
Abstract: PURPOSE: To effectively execute desulfurization reaction of molten iron by blowing a powdery desulfurizing agent by a carrier gas contg. oxygen into the molten iron and blowing a reducing gas into the molten iron at the time of the desulfurization treatment of the molten iron. CONSTITUTION: The high temp. of the reaction system, the low oxygen potential and the basicity of molten slag are the requirements as the desulfurization conditions for the molten iron and, therefore, the powdery desulfurizing agent consisting essentially of CaO is blown as the gaseous oxygen or N2 contg. oxygen, etc., as a carrier gas into the molten iron. The fall of the temp. of the molten iron by the exothermic reaction of the Si and C in the molten iron with the oxygen is prevented. The reducing gas consisting essentially of gaseous hydrogen and contg.  Co, CH4 , N2 , etc., is blown into the molten slag or the boundary of the molten iron and the molten slag, thereby the desulfurizing atmosphere is made to a reducing atmosphere to decrease the total content of the FeO and Fe2 O3 in the molten slag to >=5wt.%, by which the desulfurization treatment is effectively executed without lowering the temp. of the molten iron and the temp. deficiency of the molten iron at the time of the decarburization steel making and refining in the next converter is prevented.

Title: Magnetic head
Inventor: IWATANI SHIGEYUKI
IPC: G11B5/60
Filed: 1986-07-15
Abstract: PURPOSE:To secure flatness of the surfaces of a floating rail by making a cut part go over just one of two edge lines set in parallel to the relative driving direction of one of both rails against a magnetic disk. CONSTITUTION:A slider 1 has two floating rails 2 and 3 on its surface counter to a magnetic disk and a magnetic core 6 is fixed to a cut part 4 formed at the rear part of the rail 2 via an adhesive 5. Then a winding 10 is provided to the core 6 for formation of a read/write part. The part 4 is deflected so that it covers over an edge line 7 and not over an edge line 8 of the rail 2 respectively. As a result, an area (c) remains even though the width (b) of the rail 2 is reduced less than the width (a) of the part 4. Thus an area occupied by a slider material is increased and the satisfactory flatness is secured on the surface of the rail 2.

CONSTITUTION:The classification of the contact pattern of a tongue position is performed from the output of a tongue position detection circuit 2 and a tongue pattern but it is not always necessary to judge all of electrode points (63 points) and, with respect to closure and contraction, the contact points of two outside rows may be judged as shown by a drawing. The contraction judge processing of a contraction detection circuit 3 is performed according to a contraction judge processing procedure instance. The number of the contact points of the electrodes of one outermost row among the electrodes of two outside rows at the tongue position as shown by a drawing are calculated. The number of contact points are set to c1 and the number of non-contact points are set to n1. When all of points are in a contact state, closure is judged to set k=0. Next, the number of contact points of one inside row are calculated to be set to c2 and the number of non-contact points are set to n2. At the time of n2=0, closure is judged to set k=0. A contraction degree k=(n1+n2)/(c1+c2+n1+n2) is calculated.

Title: Speed control method of revolution motor and its device
Inventor: SEI KANSHIYU
IPC: H02P29/00
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To enhance the speed control characteristics by storing values compensating for the effect of disturbance represented by a function of angular speed and angular position through learning. SOLUTION: A learning comparator 27 receives the output from a speed controller 21, a speed instruction ω* and an angular position θ and forms an output from which the effect of disturbance is eliminated. Since the disturbance is represented by a periodic function only of the angular position θ, the learning comparator 27 converts a current instruction applied from the speed controller 21 into a periodic current instruction which is then stored. An adder A4 adds the current instruction applied from the speed controller 21 to a disturbance compensation instruction applied from the learning comparator 27 to produce a corrected current instruction which is then inputted to a current controller 23. In response to a received current instruction, the current controller 23 delivers a torque instruction to a motor 25.  Since values compensating for the effect of disturbance are determined and stored previously and eventually employed for speed control, speed control can be performed easily and efficiently.
