Title: Optical submarine repeater
Inventor: TAKAHASHI TSUTOMU
IPC: H04B10/032
Filed: 1992-09-17
Abstract: PURPOSE:To enhance the reliability of the communication of the optical submarine cable communication system in which a direct optical amplifier is employed and an optical submarine repeater is applied. CONSTITUTION:An optical branching device relating to each line (in this case, an optical branching device 30 relating to a 0th line) separates an input optical signal relating to the 0th line into a main signal and a branch signal. An optical interruptor pair relating to the 0th line (optical interruptors 50, 60) selectively passes either the main signal outputted from the optical branching device 30 or a branch signal outputted from an optical branching device 32 relating to a 2nd line. An optical isolator 40 passes through the branch signal outputted from the optical branching device 30 and an optical interruptor 61 interrupts the reflected optical signal. An optical coupler 70 outputs the main signal or the branch signal selected by the optical interruptor pair relating to the 0th line as an output optical signal relating to the 0th line. A monitor circuit 2 controls the selection by optical interruptor pairs synchronizingly about all lines based on a command from a terminal station.

Abstract: PURPOSE:To easily resegment clauses with less key operation even at the time of operator's erroneous clause resegmentation by operating a specific key like a cancel key to restore a conversion object sentence to the state just before indication of a clause resegmenting position. CONSTITUTION:A CPU 11 executes not only functions of KANA(Japanese syllabary)-KANJI(Chinese character) conversion control and clause resegmenting control stored in a ROM 12 but also the function of cancel and reconversion control by which the sentence is restored to the state just before indication of the clause resegmenting position at the time of operating the cancel key after clause resegmentation. At the time of executing this cancel and reconversion control, a homonym buffer 133 provided in a random access memory (RAM) 13 together with a retrieval table 131 and a clause table 132 is referred to generate and store KANJI and HIRAGANA(cursive form of Japanese syllabary) character strings of homonyms with respect to each clause of the KANA-KANJI conversion object sentence. Thus, clauses are easily resegmented in the case of operator's erroneous clause resegmentation.

Abstract: PURPOSE:To perform transmission to other network by the quite same consciousness as the transmission to a terminal in its own network by duplicating an intra-network token at a repeating node, and transmitting/receiving data by a false token. CONSTITUTION:The nodes 12, 13 for inter-network repeating are provided, and when the node 12 decides that the token is a destination token for other network 14 connected to the node 13, it stores said token for a while after catching it and duplicates said token and transmits the data to the repeating node 13 of the designated network 14 and when an answer is returned from other side network 14, it returns the stored token to a transmission terminal as an answer token. Besides, as for the receiving network 14, when it receives the data from other network 11, it catches the token 13 of its own network, and duplicates the data in the token, and sends the token, and when the answer token is returned, it repeats answer data to an outgoing station. Thus, a particular procedure for a gateway, etc., need not be performed in order to transmit the data to other network, and the data can be transmitted in the same way as its own network.

Title: Determination of coating width
Inventor: KON YOSHIO
IPC: B05D3/00
Filed: 1986-11-18
Abstract: PURPOSE:To reduce the loss of a coating liquid, in coating in such a case that products having a different kind of sizes are arranged in a common base, by performing the arranging way of products having a high gain ratio before determining a coating width from the max. product width. CONSTITUTION:The gain ratios of products A-M in a coating width direction are calculated from the arranging way of the products A-M set on the basis of the effective width L capable of being realized by a coating machine. The area ratio of the individual product to the total area of all of the products scheduled in production is calculated and the gain ratio at every product is multiplied by said gain ratio to calculate the substantial gain ratio of each of the products A-M. Further, the substantial gain ratios of all of the products are totaled to calculate the total gain ratio with respect to the arranging way preset. This total gain ratio shows the ratio occupied by the area of the products to the entire coating area determined by the effective width and, as the gain ratio becomes high, the loss of a coating liquid becomes little. This method is utilized in coating a roll base with the coating liquid, for example, when the printing plate material is prepared.
