Title: Clamp pulse control circuit
Inventor: ASANO TAKEHIKO
IPC: H04N5/18
Filed: 1989-02-27
Abstract: PURPOSE:To attain clamping not affected with over or deficient adjustment by extending the pulse width of a clamp pulse at unlocking so as to apply quick synchronization and decreasing the pulse width of the clamp pulse at locking. CONSTITUTION:A clamp pulse generating circuit 14 generates two kinds of clamp pulses, long and short pulses based on a horizontal timing pulse. While an unlock signal is outputted from a clock recovery distribution circuit 6, the clamp pulse with a long width is selected and an input video signal is clamped in a quick clamp time constant equivalently. Thus, the locking is attained in a short period. After the end of locking, when no unlock signal is outputted from the circuit 6, the clamp pulse with a short width is used. As a result, the input video signal is clamped so as not to be affected by over adjustment or deficient adjustment caused at the left and right edge of a horizontal synchronizing signal. Thus, the production of hue change disturbance of a reproduced picture is prevented.

Abstract: PURPOSE:To provide a device for casting a sheet capable of producing the sheet which has a sufficient and uniform thickness and is free from inclusion of slag, etc., by installing a linear motor and gate to a trough mounted together with water cooling rolls on a pressurized pouring furnace and constituting the device in such a manner that the sufficient contact length between a molten metal and the water cooling rolls is obtd. CONSTITUTION:The lower water cooling roll 8 and the upper water cooling roll 9 are rotated upon starting of casting. A pressurized gas is conduced from a pressurized gas system 12a to the pressurized pouring furnace 12 to raise the molten metal 4 in the furnace 12 up to the molten metal surface. The molten metal level is so controlled by a molten metal level control system 12b that the level stops at said position. The linear motor 3 is already energized during this time to press the molten metal 4 in the transverse direction of the rolls 8, 9 by equally distributed thrust. The molten metal 4 starts solidifying at the contact surfaces with the rolls 8, 9. The solidified and adhered film increases as the rolls 8, 9 revolve until finally the thickness is controlled to a prescribed thickness at the point of a min. gap between the rolls 8 and 9. The solidified metal is taken out in the form of the sheet.
