Abstract: PURPOSE:To prevent sticking of metal to free board in a ladle and to prevent pick-up of C and N in molten steel by submerging a molten steel submerged tube formed with a top plate having opening hole, cylindrical type iron plate and refractory and having the outer diameter smaller than inner diameter in a ladle, into molten steel in the ladle. CONSTITUTION:The molten steel 12 submerged tube 30 supported at the upper end of the ladle 2 is formed with the top plate 32 having opening hole, the cylindrical type iron plate 31 and the refractory 36 and the outer diameter thereof is smaller than the inner diameter of the ladle 2 and the lower part thereof has length to be possible to submerge into the molten steel 12. At the time of executing decarbonization by supplying oxygen in vacuum, as high pressure oxygen jet from tip part of oxygen lance 5 is blown on the surface of molten steel 12, splash is developed, but by inserting the submerged tube 30 into the ladle 2 and submerging it into the molten steel 12, the splash is stuck on the surface of the submerged tube 30. After completing the carbonization by supplying the oxygen, the lance 5 is taken out to out of the system, and the cover 4, etc., for the ladle 2 is retreated from the upper part of the ladle 2 to take out the submerged tube 30 sticking the metal in a ladle 2 to out of the system. Therefore, the stuck metal at the free board part 16 in the ladle 2 is eliminated and the pick up of C and N in the molten steel 12 can be eliminated.

Title: Light receiving circuit
Inventor: SASAKI CHIHARU
IPC: H04B10/60
Filed: 1995-03-17
Abstract: PURPOSE: To provide a light receiving circuit which generates no secondary distortion by eliminating the output signals of two amplifiers in a multiplexing state of these signals. CONSTITUTION: A photodiode 11 has a cathode terminal that is grounded via a coil 13 and an anode terminal that is connected to a DC power supply via a coil 12 respectively and is used as a photoelectric conversion means. Thereby, two electric signals having the same levels and the phases inverted to each other are obtained in response to the received optical signals. At the same time, these two signals are amplified at two amplifier parts having the same transmission functions and then outputted after the multiplexing applied to both signals with one of them kept inverted. In such a constitution of a light receiving circuit, the secondary distortion components which are generated at both amplifier parts are eliminated in the multiplexing state of both signals. Therefore, no secondary distortion component is contained in the output.
