Title: Molten metal vessel and repairing method therefor
Inventor: TERAO MASARU
IPC: F27D1/04
Filed: 1992-08-05
Abstract: PURPOSE:To provide a molten metal vessel and a repairing method therefor, in which only local damaging part can be repaired. CONSTITUTION:In the molten metal vessel (tundish, ladle, etc.,) in which only the peripheral part of the local damage estimation part (the part having possibility of local damage) is preliminarily constituted of carbonaceous refractory, e.g. the tundish is lined with brick 2 ordinarily used as the lining material and also, the peripheral part of locally damaged portion is lined as a picture frame state with carbon-containing brick 3. As the repairing means, only the brick 2a part damaged as bounding the picture frame of the carbon-containing brick 3 is picked up and dismantled and this dismantled removal part is again lined with the brick 2a or repaired with monolithic refractory. Therefore, the lining material in the molten metal vessel is locally damaged or eroded, and even if the integrative phenomenon is accurred, this phenomenon is limited due to the carbon-series refractory constituted in the peripheral part thereof, and this damage is not spread to the whole body, but limited to only the local part.

Title: Immersion nozzle for continuous casting
Inventor: KAWAI KENJI
IPC: B22D11/10
Filed: 1994-09-22
Abstract: PURPOSE: To more surely introduce an inert gas for removing inclusions into a casting mold under continuous casting and to more effectively decrease the inclusions of the resulted slab by embedding a perforated body into the inside wall surface near the upper part in the molten metal discharge port of the casting mold, thereby forming gas ejection holes. CONSTITUTION: The discharge port of an immersion nozzle 1 and the perforated body 11 are immersed in a position lower than the surface of the molten steel 6 in the casting mold 5 and an inert gas supplying pipe is connected to a gas introducing port 8, through which pipe, gaseous argon is supplied under pressure at the time of casting. Then, the gaseous argon supplied under pressure to the gas introducing port 8 passes a slit-like gas introducing hole 12 and is blown in a fine bubble form into the molten steel 6 prior to discharge in the immersion nozzle 1 by passing the perforated body 11 having the many fine open pores. The gaseous argon is discharged into the casting mold 5 right thereafter and, therefore, the state of blowing the fine inert gas into the molten steel 6 in the casting mold 5 is attained and the inclusions in the resulted slab are decreased.

IPC: H04L7/033
Filed: 1986-09-29
Abstract: PURPOSE:To decrease the error rate of an identification signal by making the characteristic of a phase detector unchanged with respect to pattern fluctuation of an input signal so as to reduce timing jitter due to the pattern fluctuation of the input signal. CONSTITUTION:A phase error signal detected by an identification circuit 111 and an exclusive OR circuit 112 is selected by a changeover switch circuit 118 while timing information is included in the input signal. Further, when the timing signal is not included in the input signal, the phase error signal by the timing information just before stored and delayed by a delay circuit 119 is selected and even if the pattern of the input signal is fluctuated, the phase comparison characteristic is made unchanged. Thus, the characteristic of the phase detector 11 is not changed against the fluctuation of the input signal, then the fluctuation of locking width of the phase locked loop or jitter is decreased sufficiently due to the pattern fluctuation.
