Title: Optical fiber cable
Inventor: SUGATA FUMIO
IPC: G02B6/02
Filed: 1989-02-22
Abstract: PURPOSE:To simplify a structure, to facilitate the manufacture, and to reduce a diameter by passing an optical fiber for a CO2 laser through an annular optical fiber which can guide visible light. CONSTITUTION:The optical fiber 1 for the CO2 laser made of metal halide is inserted into the annular quartz fiber 6 which can guide the visible light. By such a structure, the annular quartz fiber 6 serves as a conventional protection tube and can guide the visible light, so a conventional quartz tube is not necessary to realize the structure which is manufactured extremely easily. Then the cable diameter is therefore reducible. Further, when the optical fiber 1 for the CO2 laser deteriorates during the use of a laser device, the annular quartz fiber 6 is also fused to cut off the visible light. Namely, the visible light is monitored to detect the deterioration of the optical fiber 1 for the CO2 laser.

Title: Method and device for combining light radiated from multi-mode optical fiber
Inventor: TSUJIKAWA HIDEO
IPC: G02B6/32
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To increase flexibility, reduce curvature, and simplify handling, by collecting light to one multi-mode optical fiber by bundling a plurality of optical fibers and using a condensing lens system. SOLUTION: Light going out of a multi-mode semiconductor laser is collected to a multi-mode optical fiber 1 doped with germanium. For example, nine optical fibers 1 formed by integrating a multi-mode semiconductor with the multi-mode optical fiber are tightly bundled in a bundle shape. These are condensed by a substantially unmagnified imaging lens system 4 to a multi-mode optical fiber 8 doped with germanium. In this case, quantity of light can be measured by arranging, for example, a light receiving element 6A at a part of the unmagnified imaging lens system 4, and a desired quantity of light can be easily adjusted even during an operation.  When it is arranged at the 6B position, reflection amount of quantity of light becomes large from a reference state when flaw or defective occurs on the end surface of the fiber 1, and situation of the end surface of the fiber 1 can be recognized.

Abstract: PURPOSE:To extend the arrival distance of the jet of hardening material to construct a hardening material injection layer having high density by constructing an improved foundation layer through the pulling up injection of an injection rod to facilitate the rotary flow of fresh water, and securing a cavity for injecting hardening material. CONSTITUTION:Fresh water is jetted through an injection nozzle 3 as an injection rod 1 is made to recede toward an inserting port with its rotation for excavatingly agitating soil surrounding the injection rod 1 and crushing it. In this case, injection pressure is directed toward the inserting port to activate the discharge of rotarily flowing excess water by the injection of fresh water, and viscous soil is thereby excluded to construct an improved foundation zone A. In addition, the injection of fresh water is changed to the injection of hardening material at a fixed portion to inject the hardening material into the improved foundation zone A as the injection rod 1 is insertingly advanced to a fixed depth with the rotation of the injection rod 1. The injection pressure is directed toward a deeper position inversely to the case of injecting the fresh water, and a hardening material injection layer B constructed with the lowering of the injection rod 1 is set on the upside to serve as a packer. Thus the sliming of the hardening material can be prevented to improve the consolidation effect of the hardening material injection layer B.
