Patent JP-S59221026-A (JP)
Title: Receiving circuit of digital signal
Inventor: FUJII YASUHIRO
IPC: H03K5/08
Filed: 1983-05-30
Abstract: PURPOSE:To reproduce faithfully the pulse width of an output signal to be reproduced although an input signal is minute by constituting a receiving circuit so that the discriminating level of a comparator is equal to 1/2 variance degree of an amplifying circuit. CONSTITUTION:The input signal supplied from an input terminal 1 is amplified by an amplifying circuit 2 and applied to a comparator 4. The circuit 2 delivers a signal l1 and produces the DC voltage V0 when no signal is supplied to the terminal 1. The 1st reference voltage circuit 22 produces the voltage V0. A peak detecting circuit 5 detects the peak value of the partial pressure at a juncture 23 between resistances 20 and 21. The 2nd reference voltage circuit 24 delivers the action point voltage VC of the circuit 5. The voltage of the juncture 23 is shown by a line l2. When this voltage of the juncture 23 is higher than the point VC, the output of the circuit 5 is set at V0+V/2, where V shows the variance degree of the output of the circuit 2 and a line l3 shows the output of the circuit 5. Thus the discriminating level of the comparator 4 is set at V/2. This prevents the variation of the discriminating level which is due to the point VC.

Title: Azimuth detection unit
Inventor: KOSHIO TATSUYOSHI
IPC: G01S3/54
Filed: 1978-08-08
Abstract: PURPOSE:To make it possible to detect the direction of a horizontal polarization signal over the entire circumference direction by using a horizontal polarizing antenna composed of horizontal polarization cross dipoles. CONSTITUTION:Assuming that a radio wave would arrive nearly from direction E, discriminator 21 when switching driver 21 selects a dipole parallel to the N-S line makes a decision on a larger amplitude than that of a dipole parallel to the EW line and stop the selection in this state. In this state, the Doppler direction detection system operates to know the accurate arrival aximuth. When the signal source is in a direction close to N or S, the amplitude is larger than that of E-W-directional dipole, so that switching driver 22 will stop the selection with dipole signal E in the E-W direction selected. In this way, the direction of a horizontal polarized-wave signal can be detected over the entire circumference direction.
