Title: Device for preventing slag from being input into degasification vessel
Inventor: KIM HAE WON
IPC: C21B3/00
Filed: 1998-12-16
Abstract: PURPOSE: A device for preventing slag from being doped into a degasification vessel is provided to block up slag doping into a suction deposition pipe by inputting a seat plate on the surface of the slag of a metal receiving ladle wherein suction deposition pipes of a degasification vessel are deposited. CONSTITUTION: By rotating a motor(57) one time by a controller(74), a pushing cam(58) rotates one time and pushes a pushed head(60). A steel rod(61) descends while pushing a compressing spring. A rotary shaft(64) is rotated by an operation link(63). If the pushing cam rotates one time and is returned to the original position, the pushed head ascends by the elasticity of the compressing spring. The rotary shaft is rotated reverse by the operation link and a pushing bar(68) is moved rearward by a seat plate standby gap. If the pushing bar is released from the seat plate standby gap, a seat plate in the lowest layer among the seat plates stored in a seat plate hopper(50) is filled in the seat plate standby gap. The seat plate(56) placed on the surface of the slag wherein suction stack pipes are deposited is sealed while being adhered on the lower end of the suction stack pipes when a degasification vessel(1) is deposited. The seat plate is stacked on the molten metal by passing a slag layer with the suction stack pipe. Thereby, the inflow of slag into the suction stack pipe is blocked up.

Filed: 1998-12-31
Abstract: PURPOSE: A method for assigning radio resources in the IMT-2000(International Mobile Telecommunications-2000) network is provided to assign radio resources dynamically. CONSTITUTION: If a terminal requests connection setup, an RACAF(Radio Access Control Agent Function) requests the assignment of necessary resources to an RACF(Radio Access Control Function)(S1). The RACF inquires an RNCF(Radio Network Control Function) whether the available amount of the requested radio resources exists(S2). The RNCF calculates an available storage amount(S3) and determines whether the available storage amount is more than the requested resource amount(S4). In case that the available storage amount is more than the requested resource amount, the RNCF forms new usage resource amount information by adding assignment resource amount information(S8). The RNCF permits the usage of the resources corresponding to assignment resource amount information for the requested resource amount so that the RACF can set up a radio access link(S9).

The precursor powder of the quasi crystal state is re-mixed so as to be distributed lithium salt uniformly. The precursor powder of the quasi crystal state is annealed during 12 hours at 700 to 900°C, thus a crystalline active matter is obtained. A quasi metal 0.1 to 10 weight% is added to the anode active matter thus fabricated.

Abstract: PURPOSE: The present invention is provided to acquire gene of cytochrome bd type quinol oxidase of Coryneform bacteria. CONSTITUTION: A process for gene coding cytochrome bd type quinol oxidase consisted of synthesizing oligonucleotide by using nucleotide sequence of N-terminal of subunit I, N-terminal of subunit II of cytochrome bd type quinol oxidase of Brevibacterium flavum as a base, obtaining gene coding cytochrome bd type quinol oxidase of B. flavum from chromosome e DNA library Brevibacterium lactofermentum using said amplification piece as probe by PCR(polymerase chain reaction) using said oligonucleotide as primer and chromosome DNA of B. flavum as mold.
