CONSTITUTION:The junction capacitance having a polarity is used as the capacitor 34 for correcting the internal phase and a voltage of 0.3V subtracting a voltage drop's share 0.3V of a diode 29 from a potential difference of 0.6V between a base-emitter potential 0.7V and a collector-emitter potential 0.1V of a transistor (TR)30 is applied forward to the junction capacitor 34 by a constant current source 31 and the diode 29, the junction capacitance 34 acts at a point where the current of the rising characteristic of the operating current is small, thereby preventing an overcurrent from flowing to the TR30. A constant current source 28 is provided to cancel a current from a bias current source 31 flowing to a differential amplifier.

摘要： PURPOSE:To reduce the waiting time until a replay message and a business message are accessed by providing a semiconductor memory in place of a tape recorder to access the reply message and the business message. CONSTITUTION:Since the reply message and the business message are accessed in RAMs 61, 62, the message are accessed momentarily and they are not entirely kept waiting. Since the RAMs 61, 62 are used, the equipment is not large in size as the case with a tape recorder and the equipment is nearly the same size as that of a conventional telephone set. Further, the durability is excellent.

CONSTITUTION:The collector and emitter of a control TrQ7 are connected between an output terminal T1 for extracting the reference voltage and an input terminal T2 to which an input voltage (power supply voltage) is supplied. Resistors R1, R2 and a current detecting TrQ1 are connected in series between the output terminal T1 and the earth and a TrQ5 is connected to said serial connection to form a current mirror circuit 1. In addition, Trs Q3, Q4 constitute a current mirror circuit 2, a TrQ6 is connected as an inversional amplifier and connected to the base of a TrQ7. Consequently, the difference (i2-i1) between the collector currents i2, i1 of the Trs Q2, Q1 flows into the base of the TrQ6, the currents i1, i2 are stabilized at fixed values by the negative feedback function and the reference voltage V stable against the temperature change can be obtained.

摘要： PURPOSE:To make the circuit stable, by connecting a series circuit of a power supply and a resistor to the 1st transistor (TR), clamping the collector to the 2nd TR, and generating a reference voltage through the constant current drive of the 1st TR. CONSTITUTION:A constant current i0 is given to the 1st TRQ5 via a resistor R5 from a constant current source 4 and a reference voltage v0 is generated at a connecting point (line 5) between the resistor R5 and the current source 4. The reference voltage v0 is represented as V0=i0R5+VBE, where VBE is a base- to-emitter voltage of the 2nd TRQ6. The collector of the TRQ6 is connected to the line 5, the current fluctuation of the constant current source 4 when a power supply voltage +B is fluctuated, is abosrbed to make the current of the resistor R5 constant. The reference voltage generated on the line 5 is led to an output terminal 6 via a voltage follower circuit 3. The circuit 3 generates the same voltage as the voltage v0 applied to the base of a TRQ7 of a differential amplifier 9.
