Title: Structure of iron shell in tundish
Inventor: SAKAKIYA KATSUTOSHI
IPC: B22D41/02
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent the development of protrusion, opening of joint part and crack caused by expansion/shrinkage of a refractory and to prevent the deformation of an iron shell caused by expansion of a refractory by forming the side wall of the iron shell as double structures of an inside iron shell and an outside iron shell so as to be shiftable to the inside iron shell corresponding to the expansion of the refractory. SOLUTION: In the iron shell structure of this tundish having long side iron shells 5b and short side iron shells 5a, elastic members 10 are arranged between the short side iron shell 5a and the inside short side iron shell 5aA and then, the inside short side iron shell 5aA is shifted to the short side iron shell 5a so as to absorb the expansion of the refractory. In this way, occurrence of the penetration of metal and fall-down of refractory is avoided by preventing the development of protrusion and crack, and service life of the tundish is extended. Further, since stress in the side wall iron shell caused by the expansion of the refractory is not developed, deformation of the iron shell and development of crack can be restrained.

Title: Time base correcting device
Inventor: MORIYAMA YOSHIAKI
IPC: H04N5/953
Filed: 1988-04-06
Abstract: PURPOSE:To satisfactorily correct the time base up to a high band by inputting a time base error component detected from an input signal to a filter having a prescribed amplitude characteristic and using the filter output to correct the time base of the input signal which is delayed by a time corresponding to the delay time of this filter. CONSTITUTION:In the time base correction in a PLL, a component of a sampling clock (WCK) generated by the PLL which cannot follow up the jitter of a video signal becomes the residual time base error. A variable delay device 14 does not change the sampling clock but changes the extent of delay of the video signal in accordance with the phase error of the PLL. That is, the time base error component detected from an input signal is inputted to the filter having a prescribed amplitude characteristic, and the input signal is delayed by a time corresponding to the delay time of this filter, and the phase of this delayed input signal is allowed to coincide with that of the filter output, and the filter output is used to correct the time base of the delayed input signal. Thus, said residual time base error is cancelled by feed-forward.
