Title: Flexible tube structure
Inventor: YOSHIYAMA HIROBUMI
IPC: F16L27/12
Filed: 1993-08-03
Abstract: PURPOSE:To prevent the excessive stress concentration to a bellows pipe by setting an interlocking mechanism installed in a flexible inner pipe into a state shifted to the max. in the compression direction in a natural state. CONSTITUTION:A flexible tube 1 is equipped with a bellows pipe 2, outer blade 3 as braided pipe which is arranged on the outer peripheral side of the bellows pipe 2, and a flexible inner pips 4 arranged on the inner peripheral side of the bellows pipe 2. The inlet/outlet end parts 2a, 2b, 3a, and 3b of the bellows pipe 2 and the outer blade 3 are welded, in a superposed state, integrally with the upstream and downstream side exhaust pipes 5 and 7, having a diameter- expanded stopper 6 externally fitted. Further, since an interlocking mechanism 9 installed on the flexible inner pipe 4 is set in a state shifted to the max. in the compression direction, in a natural state, the shift quantity on the compression side of the flexible inner pipe 4 is regulated to the small value, even if the excessive axial load in the compression direction acts on the flexible tube 1. Accordingly, the generation of the excessive stress concentration to the bellows pipe can be prevented.

Abstract: PROBLEM TO BE SOLVED: To precisely and stably detect an angular velocity without being influenced by the environmental temperature by regulating the torsional rigidity of the support bar of an oscillator to a desired value, and connecting an oscillator base to the support bar fixed to a subject in one position. SOLUTION: An oscillator 10 has vibrating pieces 12, 13 protruded in +Y direction from an oscillator base 11 in substantially symmetric positions to the Y-directional axis passing the center part of the oscillator base 11 extended in X direction. It also has vibrating pieces 14, 15 having the same X-directional positions as the vibrating pieces 12, 13, respectively, and protruded from the oscillator base 11 in -Y direction. A single support bar 16 has a desired torsional rigidity, and is protruded from the center part of the oscillator base 11, and its tip part is fixed to a subject. Since the torsional rigidity of the support bar 16 is regulated to the desired value, the vibration leakage from the support bar 16 is regulated, and the detecting sensitivity is thus regulated.  Since the oscillator base 11 is connected to the support bar 16 in one position, the torsional rigidity of the support bar is never changed by the change of the environmental temperature.
