Abstract

PURPOSE:To output the relfection signal of ultrasonic wave pulse signal, with the simple circuit constitution such as differentiation circuit, integration circuit, NAND circuit and inverter circuit. CONSTITUTION:The output circuit consists of the differentiation circuit 16a and integration circuit 16b taking the output of the flip flop circuit 12 as input signal, which is set when the reception signal is present within the gate close period and reset at the next reception time, NAND circuit 16C inputted to one input end via the diode D1 for the output of the differentiation circuit 16a and inputted to another input for the output of the integration circuit 16b, inverter circuit 16d to which the output of the NAND circuit 16C is inputted to another input terminal via the diode D2, and parallel circuit consisting of the capacitor C1 and the resistor R1. The inverter circuit 16d outputs the relay drive signal.
