摘要： A fluororesin tube body (10) of an endoscope flexible tube (1) is small in diameter and thin in wall thickness to such a degree that it is difficult to maintain its cross-sectional shape by itself when the flexible tube (1) is bent to the limit. A braid (20) woven from a plurality of flat bands (21) to form a tubular shape is disposed around the tube body (10). The mesh openings of the braid (20) are filled with filling adhesive (30), which bonds the tube body (10) and the braid (20) together. The filling adhesive (30) has enough elasticity to allow deformation of the braid (20) during the bending operation and enough adhesive strength to maintain the bond between the tube body (10) and the braid (20) even when the filling adhesive (30) is elastically deformed. Consequently, the braid (20) restricts the cross-sectional deformation of the tube body (10). Thus, the limit curvature of the flexible tube (1) can be increased.

摘要： A process and apparatus for producing an elongated body changing in elastic modulus longitudinally thereof with use of polymers without resulting in variations in the outside and inside diameters of the body even when the polymers are different in extrusion characteristics or swelling characteristics. The apparatus may include a feeder 1 for extruding a first polymer in a molten state and a feeder 2 for extruding a second polymer, which is different from the first polymer in elastic modulus and similarly in a molten state. The feeders alternately discharge the respective polymers, which are continuously fed to a long-land die 5 along with a lubricant supplied from a lubricant applicator 4. The polymers are formed into the desired shape and cooled in the die 5, and thereafter extruded.

摘要： The present invention relates to an energy transmission optical fiber which is a medium for transmitting high-energy beams within an ultraviolet range such as laser beams. Since an optical fiber according to the present invention comprises a core formed of pure silica and a clad having a graded index type distribution of refractive index and said clad is disposed on an interface between the core and the clad where many structural defects are generated, the transmission loss is not increased even after the transmission of high-energy beams for a long time. In addition, since the optical fiber according to the present invention comprises the core formed of pure silica having a high melting point, the high-energy beams can be transmitted without generating a melting fracture in the core.

摘要： An improved method of preparing optical fiber preforms and optical fibers by so called rod-in-tube method, wherein before collapsing a tube to heat-adhere to a rod, a specific glass surface treating agent and oxygen gas are flowed through the clearance between the rod and the tube maintained at a high temperature, whereby an optical fiber preform free from imperfections at the interface between the rod and the tube can be produced so as to give optical fibers of low-loss. As the above glass surface treating agent, those materials are employed which satisfy the following criteria: (i) the hydrogen content thereof being not more than about 1% by weight, and (ii) the substances, produced therefrom in the presence of oxygen gas at a high temperature, having a boiling point or sublimation point of not more than the temperature required for collapsing the tube.

摘要： An endoscope apparatus has a side view endoscope 10 for side viewing an object in a radial direction of a distal end constitutional portion 14 and a balloon catheter 40. With an insert portion 13 of a side view endoscope 10 inserted in an insert tube 41 of the balloon catheter 40, the balloon catheter 40 is inserted into a blood vessel B. The insert tube 41 is provided at its distal end with a transparent balloon 42. This balloon 42 encloses the distal end constitutional portion 14. By feeding air (fluid) to this balloon 42, the balloon 42 is expanded so as to be urged against an inside wall of the blood vessel B. This causes the blood to be discharged between the inside wall of the blood vessel B and the balloon 42, thus enabling to observe the inside wall of the blood vessel B through the side view endoscope 10.
