Abstract: An apparatus for continuously cooling a metal strip, which comprises: at least one cooling roll, which is freely rotatable and in contact with a metal strip continuously travelling in the longitudinal direction thereof, for continuously cooling the metal strip, a cooling liquid flowing through the interior of the cooling roll to continuously cool same, a contact area between the surface of the cooling roll and the surface of the metal strip being controllable; and a gas cooler, arranged on the exist side of the at least one cooling roll, for continuously cooling the metal strip by blowing a cooling gas onto the surface of the metal strip so as to achieve a uniform temperature distribution in the width direction of the metal strip after the final cooling thereof, the gas cooler comprising a plurality of mutually independent nozzle headers for blowing the cooling gas onto the surface of the metal strip, and the plurality of nozzle headers controlling at least one of a flow rate and a flow velocity of the coolin

Abstract: A memory remote control device which comprises a wave shaping circuit for shaping a received remote-controlled signal and for outputting a pulse signal and an envelope signal, and a microcomputer operable to convert the remote-controlled signal into data for storage in a memory and for reproducing the remote-controlled signal on the basis of the data stored in the memory.
