Date Apr. 20, 1989.The internal cleaning of a centrifuge rotor is performed by a cleaning liquid is which pumped from a tank via an inlet channel to a central inlet chamber of the rotor during rotation thereof. A separation chamber is connected to the inlet chamber and, at different radial levels, to two outlet chambers via separate outlet passages. Cleaning liquid is discharged from the outlet chambers through a stationary discharge device having separate outlet channels. Part of the cleaning liquid discharged through the outlet channels is returned to the tank via a return conduit. The rest of the cleaning liquid is conducted directly to the inlet channel by means of an overpressure generated in the stationary discharge device. Thereby, it is possible to clean the rotor internally even very close to its rotational axis.

Abstract: PURPOSE: A device for outputting the melody of a video apparatus is provided to output a melody sound for a predetermined time when a heater of a picture tube is heated from the moment when a driving power is supplied to the video apparatus, so that a viewer can recognize a system operation status. CONSTITUTION: A system controller(20) controls peripheral devices according to data inputted through a data input unit(10). If a key corresponding to a power "on" state is selected, the system controller(20) outputs a square wave pulse to a sound output port(P4). A wave shaping unit(90) comprises as follows. An attenuator is composed of a resistor(R2) and a variable resistor(VR1) to shape a level of the square wave pulse. A wave shaping circuit is composed of a resistor(R2) and a condenser(C1) to shape the pulse as a triangular wave. A filter circuit removes a DC component from the pulse. A switching unit(60) selects an output signal of the wave shaping unit(90) and an output signal of an IF processor(50), which are supplied to two input terminals according to a control signal of an output port(P3) of the system controller(20), then supplies the selected signals to a voice signal processor(70).
