Filed: 1993-05-14
Abstract: PURPOSE:To make possible more realistic and short-time analysis by modeling straight pipes and a curved pipe of a pipeline respectively by a cylinder shell model, and carrying out operation on respective physical quantities of the pipeline by a correction transmitting matrix into which disturbed data is considered after the disturbed data of the ground by an earthquake is inputted. CONSTITUTION:One end of the first straight pipe 21 is installed in a structure 1, and the other end of this is installed on one end of a curved pipe 4 by the first joint 31. The other end of the curved pipe 4 is installed on one end of the second straight pipe 22 by the second joint 32, and the other end of this is made free. Behavior against an earthquake of a pipeline buried underground in this way is analyzed. In this case, in the first place, the straight pipes 21 and 22 and the curved pipe 4 are modeled respectively by a cylinder shell model. Next, disturbed data of the ground by the earthquake, for example, a spring constant of the ground or displacement of the earthquake and the like are inputted. In succession, by a correction transmitting matrix into which the disturbed data is considered, operation is carried out on respective physical quantities of the pipeline, for example, on pipe shaft directional stress, circumferential directional stress and circumferential directional shearing force and the like.

IPC: H01M4/26
Filed: 1992-05-06
Abstract: PURPOSE:To shorten a manufacturing time and ensure easy manufacture by using a negative electrode added with zinc metal or zinc alloy. CONSTITUTION:A negative electrode 2 and a positive electrode 3 are arrayed in order via a separator 1 of sulfonated polypropylene nonwoven cloth. The lead 2a of the negative electrode 2 is spot welded to a terminal 4, while the lead 3a of the positive electrode 3 is spot welded to a positive electrode terminal. A positive electrode plate group so made is placed in a case 5 and added with an electrolyte. Then, zinc metal or zinc alloy is added to the negative electrode 2 composed of AB2 type hydrogen storage alloy. Furthermore, the battery after constituted is heated up to or above 45 deg.C.

A part of the exhaust gas of an engine 1 is returned from the exhaust pipe 6 to the intake pipe 4 through the recycling pipe 8. The end of the recyling pipe 8 on the exhaust pipe 6 is located in the position where the diameter of lead compounds and soot in the exhaust gas becomes large and the temperature of the exhaust gas is not more than 300°C. The end of the recycling pipe is opened in the same direction as the flow of the exhaust gas. As a result, the particles of increased diameter flow downstream because of their inertia and are hardly sucked into the recycling pipe 8. Therefore, harmful emissions are stably decreased throughout a long time.
