Title: Residual energy erasing circuit of pulse transformer
Inventor: OOTSUKA TSUTOMU
IPC: H03K17/80
Filed: 1980-08-14
Abstract: PURPOSE:To eliminate the effect of bounced waves, by erasing the residual electromagnetic energy within a pulse transfomer through a circuit which is constituted at the primary side. CONSTITUTION:When a transmission mode signal e supplied to a base control circuit 4 is set at H level, the circuit 4 works to produce control pulses Pb-Pc. When a transmission signal Pa is set at H level and the circuit 4 delivers signals in which the pulse Pb is L with Pc and Pd set at H respectively, a transistor TR5 is turned off with TR6 and TR9 turned on respectively. Thus the current flowing to a pulse transformer 10 becomes ib, and the positive voltage is produced at an output Pe of the transformer 10. Then the signal Pa is at L and the circuit 4 delivers a signal in which Pb and Pc are at H with Pd at L respectively. Thus the TR5 and TR6 are turned on with the TR9 turned off. Then a current ic flows through the TR6 and a diode by the voltage caused by the energy of the bounced wave. As a result, the energy is consumed in a short time. Then the signal Pa is set at H with the signal Pb at H, Pc at L and Pd at H respectively, and thus the output Pe is turned into the negative voltage.

IPC: G01S19/41
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To receive signals from a necessary number of satellites in a short time by trying the selective receiving of the signal of each determination satellite, and detecting the range of elevation and azimuth of the satellite successful in selective receiving, and preferentially receiving the satellite signal within the range.
