Abstract: Two synthetic resin structural members (11), at least one of which is hollow, are connected by a bolt (32) which passes through the hole in a sleeve which is received in opposed holes in the wall of the hollow member. The nut is then tightened and the sleeve prevents the walls of the hollow member being deformed inwardly. A connector (22) may additionally be used, which has a plurality of holes formed in it. The bolt (32) passes through the hollow member and the connector to connect these together. The other member (11) is then connected to the connector by drilling a hole in it in a position corresponding to one of the holes in the connector and securing a blind rivet (23) in the aligned holes. The drilling and riveting steps are repeated until the required number of rivets have been secured.

Abstract: In a magnetic resonance imaging apparatus adapted for a spin-echo method using a 90° pulse as a selective excitation pulse and a 180° pulse as a refocus pulse, MR signal is acquired with their phase difference changed in increments of a fixed angle (φ) with each frequency encoding step. This permits the phase difference between an echo signal (f) used for imaging and an FID signal (fz) unnecessary for imaging to be changed in increments of the fixed angle (φ) with each encoding step. Thus, a zipper artifact based on the FID signal (fz) will be produced in a position corresponding to the fixed angle (φ) in an MR image reconstructed through Fourier transform of the acquired signal (f). The proper setting of the fixed angle (φ) of the phase difference permits the zipper artifact to be shifted to any position in the MR image.

Abstract: To make a double-walled tubular piece, a workpiece (1) comprising two tubes (3, 5) inserted one into the other at least virtually without play is bent and then preferably introduced into a cavity (57) which is bounded by a mould (51) having separable mould parts (53, 55). A fluid (79), for example water, is then forced between the two tubes (3, 5) and preferably also into the interior of the inner tube (3) and the outer tube (5) is expanded by the pressure of the fluid. At least over part of its length, there is then a free interspace (91) between the walls, formed by the two tubes (3, 5), of the tubular piece made in this way. By virtue of the fact that the workpiece (1) is bent with the tubes (3, 5) resting at least approximately with a close fit one inside the other, the bending operation and the entire manufacturing process can be carried out in a relatively rapid and simple manner. <IMAGE>
