  • Patent number: 8839191
    Abstract: An input unit of a compiler accepts a second program called by a first program. A converting unit of the compiler converts the accepted second program into a program in which an initialization instruction and a return instruction are additionally written as instructions executed when an error occurs. An execution control unit of an execution controller executes an execution file having the program where the instructions are additionally written by the compiler in cooperation with a predetermined function group. If an error occurs, an error processing unit of the execution controller initializes a resource based on the initialization instruction described in the program in the execution file having the error, and returns to a caller program based on the return instruction.

  • Patent number: 7376355
    Abstract: An optical transmission apparatus includes a return line for connecting a first transmission line and a second transmission line opposed to the first transmission line in order to make it possible to commonly use a transmitter-receiver or a repeater, for example, between a trunk line and a branch line and prevent a situation that the power of branched signal lights increases excessively. The optical transmission apparatus is configured so that dummy lights inputted together with signal lights to be added to signal lights transmitted through the first transmission line are sent to the second transmission line through the return line and are outputted together with signal lights to be dropped from the second transmission line.

  • Patent number: 7319816
    Abstract: An optical transmitter transmits a light which alternately exhibits a spectrum line width wider than a Brillouin bandwidth and a spectrum line width narrower than the Brillouin bandwidth. The transmitted light is provided to an optical transmission line so that the transmitted light travels in the transmission line and thereby causes returning light to be generated in the transmission line. An optical detecting section detects the returning light. Disconnection of the transmission line is detected from the detected returning light.
