    • PROBLEM TO BE SOLVED: To align a multiplicity of fibers 1, 1, etc., in a longitudinal direction and transverse direction, respectively, with good accuracy by making the offset of the fibers 1, 1, etc., from their array direction as small as possible when a multifiber bundle Bu is manufactured by aligning the terminal parts of a multiplicity of the fibers 1, 1, etc., in such a manner that these terminal parts line up respectively straight in both of the longitudinal direction and transverse direction. SOLUTION: Fiber sheets 13 are formed by inserting the fibers 1, 1, etc., of the number of pieces corresponding to the transverse direction of the multifiber bundle Bu respectively into V-grooves 5, 5, etc., of a V-groove jig 4 to line up the fibers to one row, pressing the respective fibers 1 in a pressurized state in such a manner that the outer peripheries of the respective fibers 1 come into contact at two points with groove flanks 5a and 5a of the V-grooves 5, 5, etc., of the V-groove jig 4 and bonding and integrating a multiplicity of the fibers 1, 1, etc., pressed and held at the V-groove jig 4 by adhesives 11. Such fiber sheets 13 of the number corresponding to the number in the longitudinal direction of the multifiber bundle Bu are laminated and pressurized to multiple stages in the state of putting the sheets between fitting groove parts 16 and 16 of a pair of sheet aligning jigs 15 and 15 and multiple stages of the laminated fiber sheets 13 are bonded and integrated.

    • PURPOSE:To curve the oscillating part at the front end to allow the observation at the desired point in a blood vessel, etc., by providing the oscillating part at the front end of a body insertion part and disposing a balloon adjacent near the base end of this oscillating part. CONSTITUTION:This catheter has the oscillating part 3 which is freely deformable straight and curvilinear as shown by a solid line and a virtual line at the front end 2 and the balloon 4 disposed adjacent to the base end side of the oscillating part 3. The outside diameter D of the body insertion part 1 is set at 1 to 4mm and the length size L3 of the oscillating part 3 is set at 10 to 40mm. A sheath tube 14 is parted to the parting position nearer the base end by a prescribed size L3 from the foremost end face 15 and consists of a 1st zone 14a on the front end side constituting the oscillating part 3 and a 2nd zone 14b connected to a metallic adapter 16 at the prescribed parting size A. The catheter which has the oscillating part 3 and the balloon 4 in combination and allows an inspection, operation or treatment by temporarily stopping the blood when inserted into the vessel is obtd. in this way.

    • PURPOSE:To obtain laser conducting fiber capable of irradiating a wide area uniformly and by once irradiation with laser light by forming a tapered tip end of laser conducting fiber, covering the fiber with a heat resistant binder having a higher refractive index than that of a clad layer of the fiber, and incorporating a scattering body in the binder dispersedly. CONSTITUTION:An insertion part 4 to be inserted into several internal organs is constituted by making fiber 1 bare from its intermediate part to its tip end part. An emitting part 9 of laser light is constituted of a cylindrical transparent sleeve 11 fitted to the outside of the main body 8 of the fiber at the tapered tip end part 10 covering the neighborhood of the tip end part, and a binder 13 contg. scattering bodies 12... dispersedly. The tapered tip end part 10 is covered by the binder 13. The binder 13 consists of a heat resistant transparent body having a higher refractive index than that of a clad layer 6 of the main body 8 of the fiber, and the scattering bodies 12 consist of glassy powder. Thus, laser light R radiates toward all directions, and can irradiate uniformly the inside of an internal organ when the fiber is inserted into several kinds of internal organs, etc.

    • PURPOSE:To prevent an optical transmission guide from being damaged with an external force and to reduce the external diameter of an object part by forming a guide holder and a part wound with metallic foil at a non-precoat part where the precoat part of an image guide is peeled off. CONSTITUTION:The guide holder 6 is formed at the tip part of the precoat part 2a of the section where the precoat 3 of the image guide as a glass fiber assembly is peeled off, and a winding layer 7 of soft metallic foil is wound around its left-side part so that its external diameter is equal to the internal diameter of an external pipe 1. This part is inserted into the external pipe 1 to form a fiber scope, whose object tip part is inserted into a combustion chamber and when the combustion state is observed, the soft winding layer 7 cuts off vibrations of an engine, so that the image guide 2 is not damaged. Further, the coefficient of linear expansion of the metallic foil 7 is nearly equal to that of the optical fiber 2, so heat expansion at high temperature is absorbed by the gap of the foil to prevent the image guide 2 from being broken, and the external diameter of the object part is reduced.
