Abstract: A vibration distribution measurement system includes a frequency sweep light source that outputs frequency sweep light, an optical splitter that splits the frequency sweep light into probe light and local light, an optical mixer that mixes backscattered light from the sensing fiber as signal light with the local light, the backscattered light being obtained by causing the probe light to be incident on the sensing fiber, and an analysis unit that analyzes a beat signal obtained from output light of the optical mixer. The analysis unit estimates a distance offset from a measurement result obtained by measuring a distribution waveform of the signal light by measuring the beat signal at a measurement time sufficiently shorter than a cycle of the vibration of the sensing fiber, and measures a distribution of a vibration at any position by compensating for the distance offset.

Abstract: A planetary gear set comprises a plurality of pinions P1, P2 meshing with a sun gear, and a carrier C that shaft-supports the pinions. The carrier has an annular peripheral wall 12 that extends entirely around outer peripheries of the plurality of pinions. Thin-wall portions 12a receded at a radially inner side are formed in the annular peripheral wall, at circumferential-direction positions corresponding to the positions of the pinions. The circumferential continuity of the annular peripheral wall secures a carrier rigidity. The formation of the thin-wall portions avoids interference between each pinion and the annular peripheral wall without involving an increased diameter of the carrier. The pinions P1 have a smaller diameter than the pinions P2. A platy wall portion 32 of a bridge portion 3 extends in the direction of a circumference of the carrier, outwardly of the pinions P1.
