Title: Error amplifier
Inventor: SHIMOKAWA SADAJI
IPC: G05B9/02
Filed: 1981-05-30
Abstract: PURPOSE:To execute a soft starting operation when an electric power source is turned on, by connecting an output terminal of a voltage detecting part of an error amplifier to an input terminal through a capacitor, and connecting it to a low potential terminal of the voltage detecting part through a high resistance. CONSTITUTION:When +voltage is applied to an electric power supply terminal 22, base voltage of the third transistor (TR)26 by a charging current of a capacitor 32 and a resistance 33 becomes higher than reference voltage by a Zener diode 29, and the base-emitter voltage becomes large. Therefore, a collector  current of the TR26 increases and a base current of a TR24 becomes about ''0'', therefore, an output current being an emitter current of a TR23 also decreases.  Subsequently, as the capacitor 32 is charged, the emitter current of the TR23,  that is to say, the output current gradually increases, and becomes a soft start.  Even if a high-frequency noise is generated and applied in the output side of the  TR23, the noise is not applied to an input terminal 28 by the capacitor 32 and  the resistance 33, in the output side.

Title: Ultrasonic detector
Inventor: KATAYAMA SUSUMU
IPC: G01S7/52
Filed: 1984-04-25
Abstract: PURPOSE:To reduce the wiring between a main body part and a detection part and simplify the constitution by driving an ultrasonic oscillator with a transmitted signal and stopping receiving operation with a scanning signal. CONSTITUTION:When a scanning signal generating part 8 turns on an analog switch ASW11 and turns off ASW12, a transmitted and received signal conversion part 14 of CH2 operates. At this time, a conversion part 14 of CH1 is not supplied with a DC voltage at a point (e) and an amplifying circuit 19 is turned off to stop reception; and a transistor Tr4 turns off and Tr2 turns off, so that a driving circuit 15 is not driven even when a transmitted signal is inputted from an oscillation circuit 5. Thus, a switching circuit 16 is controlled by connecting or disconnecting the collector resistance R8 of the self-bias type amplifying circuit 19 to control the operation of the amplifying circuit 19 for reception and also operates only the driving circuit 15 for transmission of a channel over which the amplifying circuit 19 for reception operates. Therefore, channel switching in a detection part 2 is allowed and the need for the analog switches and signal lines for individual transmitted and received signals of respective channels is eliminated, thereby simplifying the constitution.
