Abstract: PURPOSE:To attain the revision of idle communication channel information and to improve the operating efficiency of a communication channel by providing plural storage circuits storing idle communication channel information or the like and a storage data control circuit or the like. CONSTITUTION:A demand assign controller 1 sets plural idle sets of communication channel information usable by the communication terminal equipment to a storage circuit 2 and a transmission circuit 6 sends idle communication channel information at the head of the circuit 2 to an outgoing communication channel at all times. Moreover, a reception circuit 7 always monitors an incoming communication channel and receives communication channel use request information, then sends a communication channel use request reception display signal to a storage data control circuit 8. When the circuit 8 detects it, the idle communication channel information on-air at present and the reception data are stored in storage circuits 3, 4, and the idle communication channel information displayed on the circuit 2 is revised into a 2nd data. Thus, the idle communication channel information sent by the circuit 6 is revised automatically into the 2nd data and the operating efficiency of the communication channel is improved.

IPC: G02B26/10
Filed: 1991-09-25
Abstract: PURPOSE:To provide the laser beam scanning position detection device of simple constitution which can accurately detect the timing where a laser beam passes a specific position. CONSTITUTION:A laser beam is detected by a photodetector 15, whose current output is converted by a current-voltage converting circuit 17 into a voltage signal (a). A differentiating circuit 19 differentiates the signal (a) and outputs a signal (b) and a zerocross circuit 20 makes the signal (b) into pulses by a zero-cross method. An edge detecting circuit 21 is triggered with an edge of the pulsated signal (c) and outputs a pulse signal (d). A waveform shaping circuit 18, on the other hand, outputs a signal (e) which goes up to a high level when the signal (a) is higher than the reference voltage and goes down to a low level when the signal (a) is lower than the reference voltage. A latch circuit 23 latches the signal (e) as data by using the pulse signal (d) as a clock. Consequently, a pulse signal (f) is obtained which rises at the timing of the peak of the signal (a) to accurately indicates the timing where the laser beam passes through the photodetector 15.
