摘要： An optical drop-and-insert apparatus which can process an optical signal in the form of an optical signal without converting the optical signal into an electric signal. The optical drop-and-insert apparatus expands the pulse width of an optical data pulse in an optical data pulse train on an optical highway and drops the optical data pulse to form an empty bit at the bit of the optical data pulse or another bit so that a new optical data pulse may be inserted into the empty bit. Miniaturization of the apparatus and increase in processing speed can be attained by enabling processing of an optical signal while it remains in the form of an optical signal.

摘要： Mobile communication apparatus, of small size and low cost, may be installed in vehicles to afford enhanced mobile-to-mobile communications between preceding and succeeding vehicles, even over a great distance therebetween. In the preceding vehicle, a detector detects a carrier transmitted from the succeeding vehicle and a transmission controller uses the carrier, when detected, for transmitting data to the succeeding vehicle. Further, the detector in the preceding vehicle detects, from the carrier transmitted from the succeeding vehicle, whether the distance to the succeeding vehicle is in a range permitting two-way communications therebetween. The transmission controller in the preceding vehicle transmits first information to the succeeding vehicle when the detector does not detect the possibility of two-way communication, and transmits second information to the succeeding vehicle when the detector detects the possibility of two-way communications with the succeeding vehicle.

摘要： In one aspect of the present invention, a coding part of a transmitter side codes N series of input data into N+1 series of transmission data so that each of N+1 series of transmission data have frames and have the same transmission rates as those of the input data. For example, a bit transfer unit comprised in the coding part moves i-th bits of series i to the additional series N+1 where i=1 to N and a complement bit insertion unit inserts complements of an (N+1)-th bit of series 1 and (j-1)-th bits of series j into a first bit position of series 1 and j-th bit positions of series j, respectively, wherein J=2 to N. A frame signal insertion unit units alternate frame signal into the series N+1. BSI is secured by this simple construction.

摘要： A phase adjusting circuit for adjusting a phase of each bit of serial data by synchronizing with a system clock. The phase adjusting circuit includes a plurality of registers. Each bit of data is input into a corresponding one of the plurality of registers in a predetermined cyclic order, synchronized with a receiving clock which is extracted from the data, and outputting outputs of the registers in parallel. The outputs are each selected in a selector circuit under a control of the selector control signal in the same order as the above input to the registers. The selector control signal is generated by detecting a phase relationship between phases of the receiving clock and the system clock, and generating a selector control signal having a phase which is determined according to the phase relationship. Then, each bit of the above selected output is synchronized with the system clock.
