Abstract: A communication line control system and a communication line control method have an architecture, in which if a plurality of calls that should be processed simultaneously occur in one communication terminal incorporating communication functions containing voice communications and data communications and accommodating a plurality of communication lines, a distributed control module utilizing the plurality of communication lines on this communication terminal processes only a specified call among the plurality of calls on the basis of condition data preset in a line control unit without being aware of the plurality of communication lines. With this architecture, it is feasible to enhance a general-purposed characteristic and a simplicity of creation of the software (distributed control module) for controlling the plurality of communication lines, reduce a load thereof and improve its usability.

Abstract: To provide a fuel sealing structure capable of preventing the leakage of not only liquid fuel but also gasified fuel, an annular packing 30 is interposed between an annular sealing surface 15 on an opening part 11 of a container 20 and an annular sealing surface 25 of a closure 20. The distance between the second regions 15b, 25b of the sealing surfaces 15, 25 is shorter than that between the first regions 15a, 25a. The packing 30 includes a first sealing part 31 sandwiched between the first regions 15a,25a and a second sealing part 32 sandwiched between the 15b, 25b. The second sealing part 32 is smaller in thickness than the first sealing part 31 and the difference of the thicknesses is larger than the difference of distances between the above-mentioned regions. With the closure 20 attached, the compression ratio of the second sealing part 32 is smaller than that of the first sealing part 31.

Abstract: A communication management node checks a condition of a complex communication terminal apparatus when the complex communication terminal apparatus is connected with a real-time-processing-system network, selects and generates control software and setting information data in accordance with the condition of the complex communication terminal apparatus, and downloads the control software and setting information data into the complex communication terminal apparatus via the real-time-processing-system network, so that the complex communication terminal apparatus acts as a terminal in the real-time-processing-system network.

Abstract: The invention provides an arc welding monitoring device by which it is possible to easily find how detected data such as a welding current and welding voltage correspond to trajectories of a robot, in other words, welding line information of a welding work. The arc welding monitoring device comprises means 4 and 5 for detecting at least either the welding current or welding voltage, a means 14 for storing the detected data, a means 14 for storing trajectories of a robot, and a means for displaying, on a screen display, at least either the welding current or welding voltage detected by said detecting means, and the trajectories of the robot stored by the storing means, wherein a range is determined on the trajectories displayed on the screen display, and arc welding monitoring display is enabled in compliance with the range.

Abstract: When a robot language is to be displayed and edited, a teaching apparatus or a programming pendant heretofore displays intermediate code of the robot language as expressed by characters. The operator cannot intuitively recognize motions of the robot, needs time to master the robot language, and is required to actually move the robot to confirm the correctness of the program after the robot has been taught. According to the present invention, a robot language processing apparatus includes a display device for graphically displaying a picture and designating a position in the displayed picture with a pointing device, a memory for storing a robot program, a graphical language processor for displaying an operation interval and an air-cut interval as successive lines on the display device by referring to the robot program, and controlling the display device to display the type of an operation detail at either one of the lines when the either one of the displayed lines is designated by the pointing device.

Abstract: An apparatus for setting a welding operation condition, enabling the simple setting of an operation and a welding condition is disclosed. The apparatus is provided with a welding information recording portion for recording information concerning a welding machine used in arc welding and welding operation, information concerning a welding operation such as shielding gas related information. A welding wire related information or the like, welding information inputting and outputting device is provided for inputting and outputting the welding operation information. A welding operation information setting device is provided for setting the welding operation information. A retrieving device is provided for retrieving the corresponding information from among the information in the welding information recording portion on the basis of the set information.
