A first divided voltage DC1 and a second divided voltage DC2 for generating reference transmission data can also have a voltage difference level which is kept constant. Thus, the differential data transmitting/receiving device and the differential data transmitting/receiving method have operational characteristics improved upon data transmission. <P>COPYRIGHT: (C)2011,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To provide wired spread spectrum communication equipment for facilitating the establishment of synchronism, and also to provide its communications method, and a wired spread spectrum communications system. SOLUTION: The transmission unit 20 of the wired spread spectrum communication equipment generates a spread signal based on a prescribed spread code SCs by a spread code generator. A strobe signal generator 32b and a timing gate 35 output the spread signal at each prescribed timing as a synchronizing signal S. An adder 39 superimposes the synchronizing signal S on post-spread information signal DS1-DSn. Then the adder 39 transmits the superimposed information signals DS1-DSn to a transmission line as a transmission signal. Thus, the synchronizing signal S superimposed on the information signals DS 1-DSn is the spread signal which appears at each prescribed timing, so that a sharp correlation peak is provided at each prescribed timing by obtaining correlation between the information signals DS1-DSn and the prescribed spread signal SCs at the reception side of the information signals DS1-DSn.

| PURPOSE:to obtain an isolator of simple constitution high in response speed by providing a Hall element between the gap of a yoke of the first coil winding to which analog signals are supplied, amplifying the output and feeding back to the second coil of the yoke. CONSTITUTION:Analog signals are supplied to terminals 3, 4 of a primary coil 1 wound on a yoke 2, and a hall element 6 is placed between the gap 6 of the yoke 2.

| PURPOSE:To make it unnecessary to use a large number of feedback resistance means and operation resistances and to reduce the voltage loss and simplify the constitution by providing an oscillator which outputs an exciting signal, a core having 4 windings, etc. CONSTITUTION:A process quantity P is inputted to a converting circuit 1, and the circuit 1 converts it to a current input signal Is. A core CO has the magnetomotive force-magnetic flux characteristic shown in a figure and has windings n1, n2, n3, and n4. The output of an oscillator 4 is given to the winding n3 as the exciting signal. A synchronous rectifying circuit 5 rectifies synchronously the detection signal of the winding n4 by a signal synchronized with the oscillation output of the oscillator 4, and the output signal is applied to a transistor TR3 through an amplifier 2 to control an output current Io. In this constitution, a loop including the core CO, the synchronous rectifying circuit 5, the amplifier 2, the output TR3, and the winding n1 is so operated that a signal DELTAIn detected in the winding n4 is zero if the exciting signal of a triangular wave current Iex shown in the figure is given to the winding n3 of the core CO to excite it, and thus, the output current Io corresponds to the input current Is accurately. | ||||||

| PURPOSE:To attain transmission of signals over a long distance with reduced distortions with a high frequency branching system by using a high frequency signal termination resistance as well as a resistance to terminate both ends of a primary trunk line in terms of a low frequency signal. CONSTITUTION:When a base band data signal is supplied through an input terminal 14a for base band data signal, the collector of a TR17a pulls in currents from the power supply voltage terminals 23 and 24 via resistances 21 and 22 and produces pulses. These pulses are received by line receivers 18a and 18b, and the signals sent through an antenna 1 are transmitted through a demultiplexer/mixer 19 and sent to each terminal via branching devices 3a-3c. A high frequency termination resistance 25 is connected to a high frequency output terminal of a demultiplexer/mixer 20 ; while the antenna 1 is connected to the high frequency input terminal of the demultiplexer/ mixer 19. Thus the impedance matching is given to a primary trunk line in terms of a high frequency. The resistances 21 and 22 are connected to the lower frequency output terminals of multiplexer/mixers 19 and 20 respectively in terms of a low frequency. Therefore both ends of the primary trunk line have no high impednace. This reduces the capacity of a coaxial cable as well as the signal reflection at the tip of the primary trunk line. | ||||||

| PURPOSE:To cut off an optional signal source to decrease the effect given to other signal sources and to suppress the generation of an electric power loss, by providing a combination of a switch which short-circuits the signal source and a 1/4 wavelength line between the signal source and an output terminal of an electric power compounding device. CONSTITUTION:A series circuit of high frequency switches 2-1-2-n and 1/4 wavelength lines 3-1-3-n is provided between a single load 5 and each of signal sources 1-1-1-n containing inner impedances 6-1-6-n of an electric power compounding system. The output impedance of the lines 3-1-3-n are decided by the characteristic impedance of the load 5, the output impedances of the sources 1-1-1-n and the number of signal lines connected in parallel to each other. Then optional signal sources 1-1-1-n are cut off to reduce the effects given to other signal sources 1-1-1-n. This suppresses the generation of an electric power loss. | ||||||

| PURPOSE:To eliminate an influence of an external noise and an influence of a ripple component by a power source, and to transmit a signal with high reliability by setting separately a power source of a transmitting side circuit and a receiving side circuit, executing a current conversion of a transmitting signal, and executing a current transmission. CONSTITUTION:A transmitting signal applied to an input terminal 36 is amplified by a differential amplifier 30, and also converted to a current having a variation corresponding to a signal amplitude by a voltage and current converting function of the differential amplifier 30. A current flowing to a transistor 32 is fetched from the first current inverting circuit 50, flows to a transistor 60, applied to an input terminal 76A of a receiving side circuit 22 through a current path 28A from an output terminal 74A, and flows to a transistor 86. On the other hand, a current flowing to a transistor 34 flows to a transistor 70 through the second current inverting circuit 52 and the third current inverting circuit 64, and this current is absorbed through a current path 28B from a transistor 82 of a current inverting circuit 78. That is to say, currents flowing to transistors 84, 88, respectively are synthesized, can be fetched from an output terminal 90, and a signal transmission is executed through the medium of a current. | ||||||
