Title: Detection of joint of ingot in continuous casting
Inventor: YAMANE HIROSATO
IPC: B22D11/16
Filed: 1985-04-15
Abstract: PURPOSE:To detect a joint with good accuracy, to decrease the crop quantity at the joint and to improve yield by measuring continuously the temp. of a solidified ingot and detecting the part below the set temp. as the joint. CONSTITUTION:A molten steel 3 in a ladle 2 is cast via a tundish 4 into a casting mold 6 and the formed ingot 8 is cut to a prescribed length by a cutter 16 via a guide roll group 10, leveling rolls 12 and pinch rolls 14. A surface thermometer 18 measures continuously the surface temp. of the ingot 8 and feeds a signal via a temp. converter 20 to a joint detector 22. The temp. decreases sharply at the joint and since the lower limit temp. is preliminarily set in the detector 22, the detector discriminates the joint when the surface temp. decreases to the lower temp. or below and outputs a signal to a lower limit alarm which in turn emits a signal to that effect.

Title: Receiving circuit
Inventor: OOHASHI TAMAKI
IPC: H04B1/16
Filed: 1983-05-12
Abstract: PURPOSE:To perform proper reception in comformity with a sudden change of an electric field intensity, by controlling a variable coupled circuit of a high frequency circuit and intermediate frequency circuit by means of an AGC signal. CONSTITUTION:In an area where the electric field intensity is weak, a high AGC voltage is given to varactor diodes VC1 and VC2 through a resistor R2 and it becomes difficult for high-frequency signals to pass through the diodes VC1 and VC2 because their capacities becomes smaller. Therefore, the degree of coupling between intermediate frequency transformers 3 and 4 becomes loose and their selectivity waveform becomes sharp. As a result, the broadcasting can be listened without any interference with broadcasting from adjacent stations. On the other hand, in an area where the electric field intensity is strong, a low AGC voltage is given to the diodes VC1 and VC2 and their capacities become larger, and then, a high frequency signal can easily pass through the diodes VC1 and VC2. Therefore, the degree of coupling of the transformers 3 and 4 becomes closer and the selectivity waveform becomes wider in band width. Therefore, the tone quality can be improved.
