Title: Heating and refining method of molten steel in ladle
Inventor: KATAYAMA HIROYUKI
IPC: C21C7/00
Filed: 1982-06-17
Abstract: PURPOSE:To produce quickly molten steel having high purity and cleanliness in a short time in a vessel-like ladle which can be conveyed, by refining the molten steel under reduced pressure while heating the same by plasma arcs with the molten steel side as an anode. CONSTITUTION:The molten steel 5 contained in a ladle-like vessel 1 which is provided with a refractory material 6, a cover 9, etc. and can be conveyed is heated by the plasma arcs generated from about 1-3 pieces of plasma torches 11 mounted as a cathode to the cover 9 and with the molten steel 5 side connected electrically through a refractory material 2 having electrical conductivity to an electrical conductor 8 made of metal as an anode in the stage of refining the steel 5 by adding an alloy component from an alloy adding device 12 to the steel 5, adding slag 5 thereto for the purpose of disoxidation, desulfurization, etc., blowing gaseous Ar or the like through a porous plug 3 for the purpose of accelerating mixing, stirring and floating of inclusions, and evacuating the pressure of the atmosphere in said vessel to about <=150Torr with a vacuum pump for the purpose of degassing.

Title: Electromagnetic relay
Inventor: NAGAMOTO MITSUKI
IPC: H01H50/44
Filed: 1992-04-23
Abstract: PURPOSE:To shorten a return time more than that in the case where a diode for absorbing a counter-electromotive voltage of a coil is connected. CONSTITUTION:A first coil 2 wound around an iron core 1 and a second coil 4 wound around a yoke 3 are connected to each other via a diode 8 so as to form a closed circuit, where both coils 2, 4 are such wound that the direction of a magnetic flux flowing in the yoke 3 becomes contrary to that of a current flowing in the closed circuit in the forward direction of the diode 8. If a switch 10 turns off an electric power source 9 for magnetizing the first coil 2, a counter-electromotive current of the first coil 2 causes the second coil 4 to be magnetized, thus generating a magnetic flux for reducing the residual magnetic flux. Attraction force acts when a tailing portion 5c of an armature 5 abuts against the yoke 3, so that the magnetic flux forms a closed magnetic circuit. Consequently, the armature 5 can easily be released from the iron core 1, and a return time can be shortened more than that in the case where only a diode for absorbing a counter-electromotive voltage of a coil is connected.

Title: Anti-skid controller
Inventor: INOUE HIDEAKI
IPC: B60T8/1755
Filed: 1993-04-30
Abstract: PURPOSE:To shorten braking distance by monitoring the convergence of yaw rate deviation according to the size or change ratio of the yaw rate deviation for advancing increasing pressure timing with a change from anti-skid control which carries out yaw rate control to ordinary anti-skid control. CONSTITUTION:A target yaw rate is set by a target yaw rate set means based on the output of a steering condition detecting means. Yaw rate deviation is calculated by a deviation calculating means based on target yaw rate and the output of a yaw rate detection means. The change ratio of the yaw rate deviation is calculated by a change ratio calculating means, and the size of the yaw rate deviation and the characteristics of the change ratio are judged by a judging means. The physical amount of anti-skid control is corrected by a correcting means. The fluid pressure of the respective control cylinders are controlled by a braking pressure controlling means based on respective output from respective wheel speed detecting means, the correcting means and the judging means. It is thus possible to advance increasing pressure timing with a change from yaw rate control to ordinary control.

Title: Semiconductor memory
Inventor: IWAHASHI HIROSHI
IPC: H01L27/10
Filed: 1993-04-30
Abstract: PURPOSE:To provide a nonvolatile semiconductor memory and the reading method capable of decreasing a current required for pre charging a column line than in the conventional practice and stably reading out the memory. CONSTITUTION:Column line potential control transistors 41-44 controlling the potential of the column line by means of the gate potential are inserted between transistors 31-34 for charging the respective column lines and the column lines BL1-BL4. By suppressing the potential for charging the column line to be a low value by means of the column line potential control transistors 41-44, an instantaneous current due to the precharge of the column line is suppressed to be a small value. In a reading cycle after the completion of precharging, the gate potential of the column line potential control transistor is made smaller than that at the precharging time and the occurrence of malfunction is prevented so that the potential at the potential detecting point of the column line is made not to fluctuate even when the lowering of the potential of the column line arises due to the capacitive coupling of column lines to each other.
