Title: Ship propeller with two piece propeller shaft assembly
Inventor: JIERARUDO EFU BURANDO
IPC: F16D11/04
Filed: 1989-04-14
Abstract: PURPOSE: To selectively and suitably inhibit a clutch shaft from moving back and forth during normal or reverse rotation of a gear case by providing a resilient spring clip for releasably holding the propeller shaft and a clutch shaft in a predetermined axial relation. CONSTITUTION: When a reversal gear case is operated, a spring clip 221 inhibits a clutch shaft 58 from forward moving, and accordingly, a flange 55 of the clutch shaft 58 and bevel gear 63 are prevented from making contact with each other. Thus, the clutch shaft 58 and the bevel gear 63 are rotated in the opposite directions, respectively, at a speed which is two times as high as the speed of a propeller shaft assembly 23 when a dog clutch 98 is meshed with the bevel gear 64. Further, when a standard rotary gear case is operated, the spring clip 221 inhibits he clutch shaft 58 from rearward moving so as to prevent the shaft 58 and the bevel gear 64 from making contact with each other, and accordingly both 58, 64 are rotated at a speed which is two times as high as a speed of the assembly 23 when the clutch dog 98 is meshed with the bevel gear 63.

IPC: H04B17/40
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To hardly cause a reception error of a signal light even when a wavelength of the signal light or a test light is fluctuated. SOLUTION: A test light as a pulse signal outputted from an OTDR unit 12 is transmitted through an optical line 30 via a photocoupler 13, reaches an optical waveguide type diffraction grating 23, where the light is reflected, the reflected light returns to the optical line 30 and reaches the OTDR unit 12 via the photocoupler 13. A backward dispersion light of the test light caused on the way of the optical line 30 also reaches the OTDR unit 12 via the photocoupler 13. The OTDR unit 12 detects a temporal change in the intensity of the reflected light and the backward dispersion light. A grating interval of the optical waveguide type diffraction grating 23 is changed continuously in a propagation direction of the test light and shorter at a position closer to a 1st position 30a.
