CONSTITUTION:The molten iron which is beforehand subjected to preliminary desiliconization, desulfurization and dephosphorization treatments by using NaCO3, etc. is charged into a converter 1, and mainly the decarburization, as well as desiliconization, desulfurization and dephosphorization are perfected by oxygen top blowing refining or the like, whereby the molten iron is refined to steel. Since the molten iron is refined preliminarily in this case, the required amt. of basic slag can be as small as 5-50kg for each 1 tone of the molten steel, and the amt. of the lime to be charged can be correspondingly smaller, so that the moisture to be carried from the lime into the molten steel is reduced considerably. A gas such as argon, CO2 or the like contg. moisture and nitrogen in an extremely small amt. is blown into the converter from the tuyere at the bottom thereof and the steel is tapped isolatedly from the atmospheric air through a communicating pipe 3 into a ladle 5 kept in an atmosphere of Ar or the like, whereby the absorption of nitrogen from the atmospheric air is reduced and the steel contg. nitrogen and hydrogen slightly is produced stably.

Filed: 1985-04-16
Abstract: PURPOSE:To reduce the number of persons required for setting a printed circuit board (PCB) to a conveying pallet and their labor and time thereof, by conveying the PCB with a conveyor directly without using the conveying pallet. CONSTITUTION:Each printed circuit board 10 is conveyed by a conveyor 11. And, it is stopped at a position of a stopper 12, but when a leading-in device 13 comes to a position continuing to the conveyor 11, its stoppage by the stopper 12 is released, thus this PCB 10 is transferred to the leading-in device 13. If so, the leading-in device 13 moves in a direction of an arrow E whereby the PCB 10 is transferred to a buffer conveyor 15, therefore it comes to a printed circuit board 14 for a buffer stock. One sheet of the forefront of this PCB 14 arrives at a working spot, and is made to go up with a lifter 16 whereby circuit inspection or operation of parts insertion, etc., takes place. When this operation is over, the PCB 14 is transferred onto a leading-in device 17 and moved in a direction of an arrow F, thus it is taken out by the conveyor 11.

Filed: 1987-03-31
Abstract: PURPOSE:To easily and accurately correct an error by adding or subtracting a LSB which differs in value among sampling data to or from measured current data which is digitized. CONSTITUTION:A voltage (v) and a current (i) detected by a voltage detector 3 and a current detector 4 are inputted to sample and hold circuits 5A and 5B. Then the outputs of the circuits 5A and 5B are alternated by a changeover switch 6 and inputted to an A/D converter 7, which digitizes and stores them in a memory SIGMAW in a microprocessor 8. Then when the current (i) is larger than zero, the 1 LSB is added to the current (i) and when the current (i) is smaller than zero, the 1 LSB is subtracted from the current (i). The product of the voltage (v) and current (i), i.e. power v.i is calculated and integrated in the memory SIGMAW, whose contents are compared with predetermined electric energy P. This electric energy P is electric energy corresponding to the 1 LSD of a display device 9 and when the data in the memory SIGMAW exceeds the electric energy P, display processing is carried out.
