摘要： An AGC circuit according to the present invention comprises: a gain controller, having a variable gain, for amplifying an input signal at a predetermined gain and generating an output signal, and for varying the gain; a comparison circuit for comparing an amplitude of the input signal or of the output signal with a predetermined reference level, and for generating a control signal that goes to a first level when the amplitude is smaller than the reference level, and that goes to a second level when the amplitude is greater than the reference level; and a duty ratio detector for supplying the control signal generated by the comparison circuit, and for generating control code in accordance with a duty ratio of the control signal, wherein the gain of the gain controller is varied by using the control code, and so adjusted that the duty ratio of the control signal is maintained to be a predetermined value. When the amplitude of the input signal or the output signal is increased, a period during which the amplitude exceeds the reference level is also extended. By utilizing this phenomenon, a gain is varied so as to maintain a control signal duty ratio of 50%, for example, so that the amplitude of the output signal is amplified to a desired value, which is maintained.

The comparator compares a compared voltage with a rectified and smoothed signal of an input signal of the compander circuit or an output signal of the first volume controller receiving the input signal, the compared voltage being an output signal of the second volume controller. The counter executes a count operation on an output signal of the comparator in synchronism with a clock signal and controls gains of the first and second volume controllers on the basis of a counter value of the counter. The control part controls a frequency of the clock signal applied to the counter by a predetermined control signal.

摘要： A coupling comprises a plug attached to the opening of a fluid-filled container. The plug includes an inner cylinder having an opening sealed by film comparatively easily broken by a sharp tip or a blade, and an outer cylinder fitted onto the inner cylinder. A socket is connected to the plug, the socket including a connection to a fluid suction pump. A cutter section has a tip portion shaped like a triangular pyramid to gradually break the film at the opening of the inner plug cylinder when the socket is connected to the plug and also has a trunk portion continuous from the tip portion and shaped like a triangle pole. An inner cylinder is carried by the socket and has a valve synchronous with the sucking operation of said fluid suction pump to open and close a fluid passage in the inner cylinder. A sleeve having a collar rotatably fitted on the inner cylinder and cooperative with a stopper on the outer plug cylinder serves to detachably fix the inner socket cylinder in the plug.
