Title: Method and device for monitoring optical fiber light loss
Inventor: AOMI YOSHIYUKI
IPC: G01M11/02
Filed: 1991-12-17
Abstract: PURPOSE:To enable monitoring of light loss of an optical fiber cable to be automated and man-power saved by switching an optical fiber to be measured automatically while changing a luminous wavelength of a wavelength variable rear scattering light measuring part (OTDR) in sequence. CONSTITUTION:For example, an optical pulse with a wavelength of 1.50mum which is emitted from an OTDR 401 impinges on a light-synthesis branching filter 403 through an optical code 402, reaches an optical connector 404 by branching operation, impinges on an optical fiber conductor 407 of an optical fiber 410, and then a rear scattering light of the conductor 407 returns to the OTDR 401 through an inverse path. The OTDR 401 averages characteristics of rear scattering light by a plurality of optical pulses for one optical fiber to be measured and then improves S/N ratio, thus enabling final rear scattering light characteristics to be determined. A data-processing part 412 compares the rear scattering light characteristics with a standard data of rear scattering light characteristics of the conductor 407 which is received by a data- accumulation part 411 according to comparison of distance and then transmits a signal to an alarm display 413 if there are points where the characteristic difference is equal to or more than, for example, 0.5dB/km.

Title: Pressure detector and method for adjusting spring setting load therefor
Inventor: ITO NORIHISA
IPC: B60C23/04
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a pressure detector of simple structure wherein the airtightness of a housing can be kept easily and a method for adjusting spring setting load therefor. SOLUTION: When the air pressure in a tire becomes large, a pressure receiving member 24 extends a bellows 23 and displaces it to the left, thereby allowing a movable magnet 25 to be close to a rotary magnet 28 and set the lower part of the magnet 28 to S polar. On the other hand, when the air pressure therein becomes small, the member 24 compresses the bellows 23 and displaces it to the right, so that the magnetic field of a stationary magnet 27 becomes superior, thereby turning the magnet 28 by half and setting the lower part of the magnet 28 to S polar. The air pressure value in the tire during half- rotation of the magnet 28 is adjusted by changing the setting load value Fth of a spring 26.  Since a lid 21 holding the spring 26 can be press-fitted to a cylindrical case 20 in the compressing direction of the spring 26 and shifting direction of the magnet 25 as well as in such a direction the same as compressing direction of the bellows 23, the load of the spring 26 can be adjusted easily.
