IPC: H01L21/82
Filed: 2001-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for laying out a dummy pattern, by which no wiring delay occurs and a sufficient open area ratio can be attained. SOLUTION: The degree of wiring margin is classified for each wiring, by using the necessary information inputted in steps S1-S3 (S4). Then the spacing constraint between wires of each wiring is set according to the determined classification of the degree of wiring margin (S5). The wiring width is corrected for adjusting the opening rate (S6). In this step of correcting the wiring width, the width of each wiring is enlarged, up to the maximum width according to the maximum wiring information inputted in the step S2.

Title: Nut mounting structure in joint metal fitting
Inventor: MINEZAKI AKIHIRO
IPC: E21D11/04
Filed: 2001-03-05
Abstract: PROBLEM TO BE SOLVED: To facilitate connecting work and to prevent generation of a crack after connection. SOLUTION: A connection rod R is fixed in a predetermined position without moving at all because a nut is precisely fixed in the predetermined position of a housing case 2 by means of a rubber plate 3, a tilting elastic part 2b, and a positioning projection part 2c. Therefore, connection work for forcibly inserting the connection rod R between wedge blocks can be carried out properly. If shearing stress is applied to the connection rod R in the connected condition, the rubber plate 3 is elastically deformed and horizontally shifts the connection rod R in the radial direction with the nut. If external force tilting the central axis line O of the connection rod R is applied to the connection rod R, the tilting elastic part 2b and the rubber plate 3 are elastically deformed to tilt the connection rod R and the nut.  Therefore, the external force is absorbed, and consequently, generation of a crack due to the external force can be prevented.
