Title: Radio telephone equipment
Inventor: SASAKI OSAMU
IPC: H04B1/16
Filed: 1994-01-19
Abstract: PURPOSE:To make possible the control of a reception input level without increasing the number of components by decreasing the base bias of low noise amplification and operating a switch so as to decrease the gain when it is judged that the level is stronger than a certain value. CONSTITUTION:This equipment is composed of a variable gain amplifier 1, radio frequency filter 2, first mixer 3, intermediate frequency filter 4, local oscillation filter 5, level detection part 6, attenuation selection and decision part 7 inside a control part, and selective attenuation changeover switch 8. A signal received from an antenna and a DC signal, whose frequency is converted, corresponding to the level detected by the RSSI level detection part 6 is transmitted to the control part. An RSSI output is correlated with the received signal level and when it is judged by the attenuation selection and decision part 7 that the reception input level is stronger than a certain value, the reception level is reduced by decreasing the base bias of the low noise amplifier 1 and operating the switch 8 so as to decrease the gain of the low noise amplifier 1.

Title: Picture signal transmitter
Inventor: HIRANO YASUHIRO
IPC: H04N7/169
Filed: 1984-01-17
Abstract: PURPOSE:To secure the secrecy to picture data of either analog signal or digital signal by applying a replacement to the picture data through the frequency conversion and transmitting the picture data. CONSTITUTION:A replacement is applied to the picture data (signal 1) on one scanning line through the frequency conversion to obtain a signal 2. The signal 2 is transmitted. A normal receiver gives a replacement again to the signal through the frequency conversion to decode it to a control signal 1. While a wiretapper receives the signal 2 and therefore is incapable of identification of the picture data transmitted. In such a way of transmission, the secrecy can be secured to picture data of both analog and digital signals.

Title: Repeater
Inventor: OBATA SHINICHI
IPC: H04B7/212
Filed: 1992-01-16
Abstract: PURPOSE:To prevent a relay reference value from being fluctuated even on the occurrence of a temperature change. CONSTITUTION:A temperature detection circuit 13 detects a temperature of the repeater, an arithmetic operation circuit calculates a correction value based on its detected temperature and outputs a correction value signal representing the correction value. A switch circuit 16 outputs a correction signal from an arithmetic operation circuit 14 to a subtractor circuit 18 when no fault detection signal is inputted from a fault detection circuit 15. The subtractor circuit 18 subtracts a signal from the switch circuit 16 from the signal outputted from a reference upper limit generating circuit 17 and outputs a relay reference value signal representing a relay reference value being the subtraction of the correction value of the relay reference value from the upper limit of the relay reference value. When a fault takes place in the arithmetic operation circuit 14, since the detection circuit 15 outputs a fault detection signal, the switch circuit 16 stops the output of the relay reference value signal from the arithmetic operation circuit. Thus, the relay reference value signal whose value is zero is inputted to the subtractor circuit 18 and the signal representing as it is the upper limit of the relay reference value generated by the circuit 17 is outputted.
