Abstract: PURPOSE: To prevent the component defect of molten steel produced by a converter, the degradation in yield and the erosion of in-furnace refractories by detecting the slopping which arises during converter operation with a contactless displacement sensor and executing the operation to suppress the slopping. CONSTITUTION: This device is provided with the contactless displacement detecting means consisting of a reflector 11 mounted at the upper part of a lance 4 and a laser displacement sensor 12 which irradiates the reflector 11 with a laser beam and measures the displacement of the lance 4 by receiving the reflected light thereof at the time of decarburization refining of the molten steel 2 by immersing the lance 4 into the molten slag 3 in the upper part of the molten steel 2 in the converter 1 and injecting gaseous oxygen from its front end. The vibration by foaming of the molten slag 3 is detected by the contactless displacement detecting means via the lance 4 if there is a possibility of overflowing of the molten slag 3 from the converter 1 by the foaming of the molten slag 3 during the converter operation.  The amplitude thereof is then compared with the previously set threshold value of the vibration amplitude of lance and the slopping is prevented by previously executing a treatment for preventing the molten slag 3 from slopping.

IPC: G11B5/596
Filed: 1994-02-14
Abstract: PURPOSE: To stably reduce an accessing time by controlling the access operation for moving a head to a target track based on a track signal and the following-up operation for following up on the target track. CONSTITUTION: A speed detector 29 detects a speed from the frequency, etc., of a track differential signal 2 and inputs the speed to a DC offset generation means 31. However, as this DC offset is desired to correspond to the speed of the head when the head of a disk storage device arrives at the target track, an DC offset corresponding to the speed of the head just before the switching of a mode from the access control to the follow-up control is outputted to charge a capacitor 33 through a closed switch 23B. In this case a means for detecting the moving direction of the head is necessitated and it is desirable to add a DC offset proportion to the speed of the head.

Abstract: PURPOSE:To prevent the increase of the noise, etc., by controlling on/off of a high frequency switch so that the on period of a switching device unconnected to an impedance element and the energy maximum output available period of a chopper circuit are not overlapped. CONSTITUTION:A chopper circuit 3 turns on/off a high frequency switch Q1 to chop the direct current, and while it rectifies to smooth the chopping voltage to convert the voltage value of the direct current to the predetermined value. An inverter circuit 1 alternately turns on/off main switching devices Q2, Q3 connected in series with the output of the circuit 3 to convert the output of the circuit 3 to the high frequency. The transient current of the device Q3 at the turn-off time is restrained by a resistance R6. A control circuit 4 turns on the switch Q1 of the circuit 3 synchronously with the off period of the device Q3. Since the on period T of the switch Q1 is shorter than the on period of the devices Q2, Q3. The off period of the switch Q1 is not overlapped with the on period of the device Q3. Consequently, the lashing current is not flowed to the device Q3 of the circuit 1, and the increase of the noise, etc., is restrained.
