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.

摘要： A pulling wire for tip articulation mechanism of endoscope is fitted with an overload preventing spring in the middle thereof. This spring is arranged to stretch upon more than a certain amount of tension. Elongation of the overload preventing spring absorbs any excessive tension which is exerted upon the pulling wire as a result of motion restriction of the endoscope. This spring is fabricated such that the material wire thereof is spirally coiled, and is simultaneously twisted so that forcing pressure is introduced in the spring in the direction in which the adjoining ring portions thereof are brought into pressure contact with one another it is subjected to tension.

摘要： Radioactive materials can be safely analyzed by an emission spectroscopic analyzer comprising an exciting device for exciting a radioactive material to be analyzed to emit light. The exciting device is enclosed in a radiation shielding wall. A detecting device detects the emitted light. The detecting device is located outside the radiation shielding wall. A light-transmitting device is provided between the exciting device and the detecting device such that the emitted light impinging on a first end of the light-transmitting device will be received at the detecting device as light having been transmitted through the light-transmitting device and emitted from a second end of the light-transmitting device. The light-transmitting device penetrates a hole made in the radiation shielding wall which has a sealing structure to prevent radiation leakage. The light-transmitting device penetrates the hole with a curvature. A lens system is attached to the second end of the light-transmitting device to permit visual observation of the emitted light therethrough. A fine adjustment device adjusts the position of the first end of the light-transmitting device in relation to the emitted light from the material to be analyzed.

摘要： A catheter consists of a torque transmitting portion which has rigidity sufficient for torque transmission and a flexible portion made of a material having a glass transition temperature for giving rigidity before insertion and flexibility after insertion. The torque transmitting portion maintains torque transmitting ability before, during and after insertion. The flexible portion maintains appropriate rigidity before and during insertion, which enables easy insertion, and gains flexibility after insertion by the body heat, which avoids hurting of the vulnerable insertion walls. Further, the torque transmitting portion may have a structure wherein a reinforcement of a coil or a braid of linear metal wires, specifically flat rectangular wires, is attached thereto to afford torque transmitting ability. Catheters having various functions and structures can be easily manufactured by extrusion-molding, or the like.
