摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for analyzing the earthquake resisting strength of a piping network capable of obtaining the earthquake resisting strength of the piping network, etc., as theoretically concrete and accurate data not by a theory of probability but by a technique of structural mechanics or material mechanics and executing simple analytical techniques in a short time. SOLUTION: An earthquake resisting strength analyzing part 200 regards total three unit elements of the piping, an rectilinear element and two boundary elements of both ends of the rectilinear element, as constituting one base element, makes the individual base elements of the piping network discrete, and analyzes the individual base elements on at least one type of displacement, distortion, and stress which occur due to vibrations and external forces caused by earthquakes. At this time, corresponding types of data are read and used for data on the deformation characteristics of the boundary elements from among data previously obtained by an infinite element method, formed into a database, and stored in a boundary element database storage part 100.

摘要： PROBLEM TO BE SOLVED: To provide a method for using CO 2 generated as a reaction product effectively without exhausting, in a process to synthesize dimethyl ether using CO and H 2 as raw materials. SOLUTION: Following step (a) and step (b) are added to the method for producing dimethyl ether (DME) where the DME is formed by reacting catalytically a mixed gas containing at least CO and H 2 as a main raw material and a recycled gas 7a' containing CO and H 2 remaining in a product gas of a DME synthesis is recycled as part of the above main raw material to produce DME9'. The step (a) is a step to prepare the mixed gas as the main raw material in a reformer R2 using a saturated hydrocarbon gas 11' as a feed gas. The step (b) is a step to separate CO 2 coexisting in a reaction product 3' formed in the DME synthesis and to recycle the separated CO 2 8' to the reformer R2 in the step (a) to use it as part of the above main raw material for the DME synthesis.

摘要： PROBLEM TO BE SOLVED: To develop a technology for charging a raw material into a raw material feed hopper to uniform the permeability of raw material in a pallet, in the cross direction of the pallet of a downward suction type sintering machine. SOLUTION: A sintered raw material thrown out of a head 3b of a shuttle conveyor 3 is dropped near side walls 4b, 4f of the raw material feed hopper 4 by correcting the track of the falling raw material 2' vertically downward by a raw material fall position adjusting mechanism 12 provided in a position close to the front of the head 3b. The coarse grain raw material is thus prevented from flowing into the vicinity of the side wall of the raw material feed hopper from the center part, and the raw material is further adjusted and charged to form crest shape near the side wall and trough shape at the center part of the raw material feed hopper so that the coarse grain raw material flows into the center part. Furthermore, a drop charge impeding means is provided for preventing the direct drop of the raw material from the conveyor head 3b to the width center part of the hopper 4 to reinforce coarsening of the average grain size of the raw material at the width center part. To correct the track of the falling raw material, a method of making the falling raw material 2' collide with a rotatable roller 15 is applied. COPYRIGHT: (C)2003,JPO
