摘要： Unwanted electromagnetic waves are eliminated in a frequency output circuit comprising an open-collector output terminal whereby radio noise can be reduced. A frequency output circuit 10 comprises an open-collector transistor Q4 with an open-collector output terminal connected to a pull-up resistor Rf connected to an external power supply Vex. A current limiting circuit 16 limits a current through the output terminal such that a high potential and a low potential of the output waveform of a frequency signal outputted by an output circuit 12 are smoothly switched. The current limiting circuit 16 is formed by a differential pair circuit of transistors Q1 and Q2 each with a resistor provided in the emitter thereof, and a current mirror circuit comprising an open-collector transistor, for example.

摘要： The time it takes for a hot-wire airflow meter to begin to operate normally upon startup of an automobile is reduced. A heat-generating resistor Rh for measuring airflow rate, a temperature-compensating resistor Rc, and a resistor R1 for detecting the current through the heat-generating resistor are connected in parallel. A differential voltage between a power supply voltage Vb and the voltage across the emitter-collector junction of transistors Q1, Q2, or Q3 is applied to each of the heat-generating resistor Rh, temperature-compensating resistor Rc, and current-detecting resistor R1. The transistors Q1, Q2, and Q3 form a current mirror circuit 20, by which the ratio of currents through the heat-generating resistor Rh, temperature-compensating resistor Rc, and current-detecting resistor R1 is determined. The current ratio is maintained to be a predetermined ratio even if the heating current is controlled by an operational amplifier 21 due to an increase or decrease in airflow rate.

摘要： A high speed dubbing is to be realized with two recording and/or reproducing units for compressed data. To this end, a magneto-optical disc 32 is read by an optical head 33 and compressed data produced via a decoder 41 are delivered to a memory 14 via a switch 37. The data are then delivered to a magnetic head driving circuit 16 via an encoder 15 for direct writing on a magneto-optical disc 2. In this manner, compressed data are directly dubbed without expansion to realize high speed dubbing.
