IPC: G11B5/39
Filed: 1990-04-27
Abstract: PURPOSE:To obtain a magnetic head having simple constitution reducing Barkhausen noise by letting a current flow to three conductors by using two power sources. CONSTITUTION:As the structure of a conductor layer, electrodes 1b and 1d are connected by a bypass conductor part 3 to form the recessed lower conductor layer, and an electrode 1a is connected to the lower conductor layer by a conductor part 4a or an electrode 1c is connected to the lower conductor layer by a conductor part 4b. Further, the electrodes 1a and 1c are electrically in contact with an MR layer 2. When using the magnetic head, for example, the electrodes 1b and 1c are connected to a zero potential, the electrode 1a is connected with a positive potential and the electrode 1d is connected with the constant current source having a negative potential. By this connection, the current flows in the three kinds of routes as follows; the first route is through the MR element 2, the electrode 1c and the conductor part 4b to the electrode 1d so that the change of a voltage between the electrodes 1a and 1c can be an MR output, the second is through the conductor part 4a and a bypass conductor part 3 to the electrode 1d and the third is from the conductor part 4a to the electrode 1b. In this case, since the negative potential is applied to the electrode 1d, the current simultaneously flows from the electrode 1c to the 1d.

Abstract: PROBLEM TO BE SOLVED: To reduce the energy loss and the wearing of a refractory by lowering steel tapping temp. of a converter in the first operation of a continuous casting to the min. limit in the necessary temp. SOLUTION: High temp. inert gas is continuously supplied into a tundish while alternately using plural heat-storage type preheaters.

This tundish temp. at the time of tapping the molten steel is accurately estimated with an approximate expression containing a function of the heat-holding time while using the last casting molten steel temp. at the previous heat as an initial value, and the steel tapping temp. at this heat is set under consideration of the temp. lowering degree, etc., at the time of pouring the molten steel into this tundish. Further, in the case of starting heat-holding of the tundish after some interval since starting of the waiting, the tundish temp. lowered during no heat-holding is estimated with a different approximate expression and while using this estimated value as an initial value, the tundish temp. during heat-holding is estimated.
