Title: Radio communication system
Inventor: KOGATA ISAO
IPC: H04B7/10
Filed: 1980-05-13
Abstract: PURPOSE:To achieve a radio communication system which has high economy and is effective to fading, by providing a dual beam antenna providing two primary radiators which transmits and receives polarized waves perpendicular to each other. CONSTITUTION:Two straight line polarized wave use primary radiators 11, 12 are provided at the focus of a mirror surface 13 of a parabola type antenna 10, and the direction of polarization is located with a slope of + or -45 deg. to the vertical direction. Another antenna 10' has similar construction. When electromagnetic waves are radiated from a transmitter TX via a circulator CL3 and a radiator 11, a direct wave 4 of the electromagnetic waves is received with a radiator 12' of another antenna 10' located to the same direction as the direction of polarization and not received at a radiator 11' located perpendicularly to the direction of polarization of the direct wave 4. The reflection wave by the surface of the reflection region 5 is received at the radiator 11', and since the direct wave and the reflection wave are separately received, no K type fading is produced. The direct wave and the reflection wave received at the radiator 12', 11' are synthesized and outputted by using receivers RX1', RX2' and a coupler C'.

Abstract: PURPOSE:To stop surely the generation of a voice signal to cut off the transmission without disconnecting a line by using a mechanical switch or a semiconductor element to provide a means, which cuts off the voice signal from a transmitter, in a telephone set. CONSTITUTION:When a hook switch 10 is hooked off to start the call, a transistor TR 4 is left furned off, and the voice signal is generated by a voltage applied to a transmitter 1 and is transmitted to the line by a network 2. If a push- button switch 5 or 6 is depressed in the call state, a high level is inputted to an AND gate 11. When only one push-button switch is depressed, the output of the AND gate 11 is in the low level still, and consequently, the TR 4 is turned off, and the call permission state is held, and only when two push-buttons 5 and 6 are depressed simultaneously, the output of the AND gate 11 becomes high-level, and an output Q of a flip flop 9 is inverted to become high-level. As the result, the R 4 is turned on to cut off the generation of the voice signal.
