Title: Optical fiber amplifier
Inventor: HORIGUCHI MASAHARU
IPC: H01S3/04
Filed: 1989-05-15
Abstract: PURPOSE:To amplify the light with a small noise and a high amplification factor by specifying the coefficient of linear expansion of secondary coating materials of an optical fiber to which a laser active material is added and cooling them to a very low temperature. CONSTITUTION:Signal light is amplified in a single mode optical fiber which is cooled by a cooling thermostat 11 and to which Er is added, and this light passes a condenser lens 3, an isolator 20, and a cut filter 16 and is received by a photodetector 14. At this time, a silicone resin is used as primary coating materials of the optical fiber 6, and thermotropic liquid crystal high polymer materials where macromolecular chains are oriented by extrusion or fluid draw ing are used as secondary coating materials. Since the coefficient of linear expansion of this liquid crystal is reduced in accordance with orientation, it is set to + or -10<-5> <0>C<-1> so that it is approximated to the coefficient of linear expan sion of the optical fiber. Consequently, the occurrence of the microbending loss due to the difference of coefficient of linear expansion is prevented at a very low temperature <=-60 deg.C. Thus, an optical fiber amplifier of high perfor mance where the noise is considerably reduced is obtained.

Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent the collapse of a tunnel itself when the middle column of an existing tunnel is collapsed by installing a spare column for preventing collapse. SOLUTION: An existing tunnel has two side walls 12 raised opposite to each other on a lower floor slab 11, a plurality of middle columns 13 raised in the center in tunnel direction, and an upper floor slab 14 placed on the side walls 12 and the middle columns 13. A spare column 16 is raised between adjacent middle columns 13, and the upper end is separated from the girder 15 of the upper floor slab 14. The spare column 16 is isolated from the upper floor slab 14, whereby, when a horizontal force acts on the upper floor slab 14 in an earthquake, the powerful horizontal force acting on the upper floor slab 14 is not transmitted to the spare column 16, and the spare column 16 is never shear-fractured.  Accordingly, the upper floor slab 14 fallen when the middle column 13 is shear-fractured is supported by the spare column 16, ant the tunnel can be used only by removing the collapsed middle column 13.
