Filed: 1994-02-15
Abstract: PURPOSE:To improve frequency characteristics with simple constitution by providing the input part of first and third current mirror circuits with emitter followers and connecting the bases of respective output transistors (TRs) to the outputs of these emitter followers. CONSTITUTION:The emitter follower is formed of the TRs Q5 and Q4 I and a resistor R3 and the base of the output TR Q6 is connected to its output. Further, the TRs Q12 and Q13 and a resistor R9 form the emitter follower and the base of the output TR Q14 is connected to the output of the emitter follower. Then, the output signal is eventually negatively feed back to the base via a collector-base floating capacitance 1 from the collector of, for example, the TR Q14 but the base of the TR Q14 is connected to the output of the emitter follower and, therefore, an impedance is so low that the fed back output signal is slight and the cancel of the input signal transmitted to the base from a differential amplifier 5 side is substantially eliminated.

Patent JP-S58135981-A (JP)
Title: Homing device
Inventor: TAKASAKI HAIMI
IPC: G05D1/12
Filed: 1982-02-09
Abstract: PURPOSE:To reduce sharply the consumption of a transmission power and to improve a tracking time or a detecting distance to a large extent, by conducting first tracking in a wide range  while receiving an echo of a target generated by a first transmission signal having low frequency being nondirectional, and by continuing the tracking with a second transmission signal switched which is a pulse-modulated wave having a narrow-angle directivity and high frequency when an underwater projectile is steered reversely beyond the direction of the target. CONSTITUTION:A low-frequency pulse-modulated wave of about 5kHz is used as a first pulse- modulated wave signal 401. Since a transmitter 1 receiving the above wave as an input has the non-directional transmission directivity characteristic, a reflected echo is easily caught and received by receivers 3A and 3B, and 3C and 3D owing to the non-directivity of a transmitted sound wave. When an underwater projectile 11 goes beyond the direction of a target 0, so as to  be opposed face-to-face thereto with the output characteristic of the receivers 3A and 3B being  reversed, a reverse steering detecting means actuates to switch the output of a transmission circuit to a second pulse-modulated wave signal 402, i.e. a pulse-modulated wave signal having a frequency several times higher than that of the first pulse-modulated wave signal 401, so as to increase the number of waves of the echo. Furthermore, this echo is delivered as a transmission sound wave having a narrow beam from a transmitter 2 having a narrow- angle transmission directivity to continue tracking.
