摘要： PURPOSE:To prevent the occurrence of malfunction by allowing an awarding device to reset a flag concerned at the time of inputting access requests from respective CPUs and set up the flag at the time of ending a memory access corresponding to the access request. CONSTITUTION:In the case of writing data into a memory 6, respective CPUs output flag reference signals 20 to 22 to respective flag holders 19. When flags are set up, memory addresses to be written and data are respectively written in address buffers 14 and data buffers 15 and simultaneously output access requests 9 to 11. The awarding circuit 5 inputting the access requests outputs the flag control signals 16 to 18 to the corresponding flag holders 19 to reset the flags, decides the priority of the CPUs, connects the address and data buffers 7, 8 of the selected CPU to the memory 6 through a memory bus 4, outputs an access signal 12 at a timing formed by a timing generator 13, and releases the requests 9 to 11. After ending the corresponding memory access, the circuit 5 outputs the signals 16 to 18 to set up the corresponding flags.

摘要： PURPOSE:To avoid reception omission of a transmission data by applying transmission control by giving/receiving of a conventional token frame after a transmission enable time of each station is circulated. CONSTITUTION:Station 101-104 are connected to a transmission line 2. When a count of a counter 9 of any station reaches a prescribed value and each station receives a data frame or a token frame multiplied with the prescribed value, the frames are sequentially allocated so that they are not overlapped among stations and only one transmission from a station is implemented by a transmission enable time when the time length reaches one period of a timer 8. Thus, when the assigned transmission enable time is circulated among the stations, the control takes over the normal transmission control by using a token. Thus, reception omission of data to be received is prevented.

摘要： PURPOSE:To diagnose a drop cable and a network connecting device and to attain the data communications between other stations during the diagnosis by providing a switch to switch a data channel, a means to receive an instruction from a station and control the switch and a terminator. CONSTITUTION:In a network connecting device 21, a switching control circuit 4 transmits a switching signal to a transmission line switching circuit 3 and a transmission line switching circuit 3 switches 91 and 92 to a terminator 2 side or transmission line couplers 51 and 52 sides. When the switches are switched to the terminator 2 side, the data sent from a station 22 through a drop cable transmitting line 13a are terminated through a transmitter receiver 6 and a driver 71, and propagated to an internal signal path 7b matched electrically. The propagated data are inputted to a receiver 81 and sent through the transmitter receiver 6 and a drop cable 13b to the station 22. Thus, the transmitting receiving system in the station 22, the drop cable and the action checking in the network connecting device 21 are executed by separating completely from a transmission line 11.

摘要： PURPOSE:To integrate the transmission route for light signals and the input/ output parts to and from an external device into one substrate and to miniaturize an electronic device by optically connecting optical connectors to both ends of coated optical fibers laid in the substrate and fixing the optical connectors to the substrate. CONSTITUTION:Two pieces of the coated optical fibers 20 are enveloped and laid in the substrate 10 and the optical connectors 30 are optically connected to respective both ends of the fibers 20. The connectors 30 are fixed via a mounting plate 40 to the substrate 10 by directing the input/output ends for light signals toward the outside of the substrate. The light inputted from the external device via the connector 30 passes the coated optical fiber 20 and goes to the other optical connector, from which the light is outputted to the other device. The light signal transmission is easily executed between the substrate 10 and the back board of the electronic apparatus as well as between the substrates; in addition, the attachment and detachment are easy and the miniaturization of the device is possible.
