Title: Modifying method of existing bridge beam support part
Inventor: SUZUKI RYOSUKE
IPC: E01D101/00
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To independently resist to inertia force without requiring the exchange of an existing support by projecting an opposite projection spacing a distance in a bridge axis direction between one of an upper structure and a lower structure and the other thereof and interposing a rubber between the projection and the upper structure or the lower structure. SOLUTION: In an existing bridge beam supporting an upper structure 1 on a lower structure 2 by an existing support 5, a projection 3 is projected on one of the upper structure 1 and the lower structure 2, and a compression deformable compression rubber 41 is interposed between the projection 3 and the upper structure 1 or the lower structure 2. The projection 3 is projected to be opposed so as to space a distance in the bridge axis direction between one of the upper structure and the lower structure and the other thereof. By such constitution, the inertia force of the upper structure 1 can be transmitted to the lower structure 2 through the projection 3 while compression force is loaded on the rubber 41. Thus, the support part can be modified so that the support part can independently resist to the inertia force of the bridge axis direction of the upper structure.

Title: Terminal attribute retrieving system for network definition
Inventor: HAYASHIDA NOBUKO
IPC: G06F13/00
Filed: 1988-08-01
Abstract: PURPOSE:To eliminate a need of reference to network definition language manuals, manuals related to terminals, or the like even at the time of designating a terminal type name as the terminal type by providing a terminal attribute table. CONSTITUTION:A user designates a source file 2 on a system, where a network definition statement requiring correction of the terminal type is registered, from the terminal equipment of an input means 1 and uses a reading-in means 3 to read the source file 2 into a virtual storage area and designates the type name of the terminal type to be corrected or the normal terminal type by a changing means 4. Since the terminal type designated by the changing means 4 has information shown in the figure in a terminal attribute table 6 referred by a retrieving means 5, the type name and the type number of the terminal can be designated. The retrieving means 5 takes out a parameter group or an address corresponding to the designated terminal type from the terminal attribute table 6 and uses a register means 7 to register it in the source file 2. Thus, it is unnecessary to refer to network definition language manuals, manuals related to terminals, or the like.
