IPC: G01S3/04
Filed: 1987-03-04
Abstract: PURPOSE:To reduce measuring errors produced on the basis of transmission characteristics by applying frequency modulation to a carrier wave by one of a signal with a phase corresponding to the arrival angle of an electromagnetic wave and a signal which is the reference of a phase and applying amplitude modulation to the carrier wave by the other signal. CONSTITUTION:The frequency modulator 311 of a multiplex modulator 31 frequency- modulates a carrier wave outputted from an oscillator 312 by a sinusoidal signal V with a phase corresponding to the arrival bearing angle of an electromagnetic wave supplied from a signal processor 14. An amplitude modulator 313 amplitude- modulates the output signal of the frequency modulator 311 by a reference signal S which is the reference of a phase supplied from a reference signal generator 15. That is, the multiple modulator 31 applies the frequency modulation and the amplitude modulation to one and the same carrier wave by the sinusoidal signal V and the reference signal S, respectively, to supply a transmission line 17 with output signals. On the other hand, the signals supplied from the transmission line 17 are halved and the sinusoidal signal V with the phase corresponding to the arrival bearing angle of the electromagnetic wave and the reference signal S which is the reference of the phase are demodulated to be supplied to a display unit 19.

Title: Variable gain differential amplifier circuit
Inventor: TAKAHASHI AKIRA
IPC: H03G3/10
Filed: 1990-02-28
Abstract: PURPOSE:To obtain a frequency characteristic not inferior to that of a basic differential amplifier circuit without increase in the load capacity by adopting the constitution such that an output DC level is decided by the sum of a voltage drop of a load resistor and a voltage drop of a level adjustment resistor. CONSTITUTION:A current of a constant current source 13 is shared to transistors(TRs) 11, 12 corresponding to a differential voltage of a power supply 14 and a control signal. A resistor 3 connects to the TR 12 and a voltage drop in response to the current shared to the TR 12 is generated across the resistor 3. Since the voltage drop across load resistors 4, 5 due to a current flowing to the TR 8 is inversely proportional to the voltage drop across the resistor 3 adjusting the level due to the current flowing to the TR 12, the output DC level at an output terminal 10 is constant independently of the gain.

Title: Radio communication system
Inventor: KOIZUMI SATOSHI
IPC: H04L1/06
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To resume communication only by one transmission disconnection, without disconnecting a communication network when an antenna system selected at the time of the transmission of a base station breaks down by permitting the base station to select an antenna, based on the presence or absence of a re-transmission request signal from a terminal station at transmission timing. SOLUTION: If the antenna breaks down, when the antenna is selected by information at the time of reception and a signal from a terminal station is transmitted in the base station, for example, the terminal station cannot receive signals from the base station. In the terminal station at that time, a timing holding/clock disconnection detection circuit 18 detects the clock disconnection, transmits it to a TMDA/TDD(time division multiplex access)/(time division duplex) control circuit 17 held when signal synchronism is normally established and transmits clock disconnection detection to a re-transmission request circuit 19.  The base station receives a re-transmission request sent from the terminal station, and can continue communication, without disconnecting the communication network for selecting not the antenna having the fault but the other antenna, so as to transmit information in the reception state.
