摘要： PROBLEM TO BE SOLVED: To solve the problems of the reliability in conventional ferrules for optical connectors made of resin being low due to the generation of dimensional abnormality of the outside diameter, their manufacture being economically difficult and their being unable to be used for connecting with a single-mode optical fiber. SOLUTION: This ferrule is provided with a fitting surface 11, which is fitted into a sleeve so as to be drawn out, a different surface 12 in level which is formed in one end side of the fitting surface 11 and has a diameter smaller than that of the fitting surface 11, an end surface 13 to which the tip end of the optical fiber is faced, a tapered surface 14 which is tapered toward the end surface 13 and is adjacent to the different surface 12 in level, a fiber inserting hole 18 which is opened in the end surface 13 and into which the optical fiber is inserted, and a coated optical fiber guide hole 19 which communicates with the fiber inserting hole 18 and into which a coated optical fiber is inserted. Dimensional abnormality of the outside diameter of the fitting surface 11 accompanied b the violent changes in the orientational property of resin, when the ferrule 10 is injection molded, is relaxed due to the existence of the different surface 12 in level.

摘要： PROBLEM TO BE SOLVED: To provide satisfactory outer diameter dimension accuracy, mechanical strength, connection reliability and economicity by providing the inside of a first cylindrical body as the inserting hole of an optical fiber and providing the inside of a second cylindrical body as the coated optical fiber guide hole of the optical fiber. SOLUTION: A ferrule 10 is made double cylindrical, one end of a first cylinder 11 becomes an optical fiber inserting hole 16. There is a flange-shaped holding part 12 around the outer periphery of the cylinder 11. At a top end opposed to the optical fiber inserting hole 16, a second cylinder 14 is protruded into the cylinder 11 while keeping a gap with the cylinder 11, and the terminal parts of the cylinders 11 and 14 are continued excepting for the inner diameter part of the cylinder 14. The cylinder 14 becomes the inserting hole of the optical fiber. Namely, the terminal part of the first optical fiber inserted through the inserting hole of the first ferrule and the terminal part of the second optical fiber inserted through the inserting hole of the second ferrule are abutted inside a connector. Such a plastic ferrule is simultaneously molded together with the holding part and the attachment process of a metal holder is omitted. Further, by using plastic, the cost of materials is reduced.

摘要： PROBLEM TO BE SOLVED: To shorten connection work while assuring reliability and to enable mass production and reduction of a connection cost by forming an optical fiber bundle consisting of continuously curved fibers enclosing a desired wiring shape and fixing part thereof to maintain the shape, then cutting away the unnecessary parts. SOLUTION: The optical fiber bundle consisting of the continuously curved fibers including the desired wiring shape is formed and the shape is maintained by fixing part thereof and thereafter, the unnecessary parts are cut away. In the case of production of, for example, optical wiring for four-fiber simultaneous connetion having an L-shaped wiring route, the single fiber-cords of four fibers of the optical wiring parts 11 to be produced have L-shaped wiring routes and the ends of the optical fibers 13 are held and press bonded by a thermal press bondable film 14, by which the wiring shape thereof is maintained. The optical wiring parts 11 are obtd. by cutting the optical wiring bundle 12 at two points a-a, b-b and cutting away the unnecessary film parts.

摘要： PROBLEM TO BE SOLVED: To provide an optical wiring component and its manufacture capable of performing mass-producing and reducing a connection cost by shortening connection work while securing reliability and saving space by reducing the occupancy space of a wiring part. SOLUTION: In this optical wiring component for maintaining a wiring shape by fixing at least a part of plural coated optical fibers 11, thermocompression- bondable films 15 and 16 or films with an adhesive are used for fiber fixation. Then, the fibers are cut to a length corresponding to the route length of a wiring route, the end parts are aligned to have a position and an angle at a prescribed input/output terminal and fixed and thereafter, fixed ends re arranged at a prescribed position. Further, the fibers between the fixed end s are aligned and at least a part of the aligned fibers is fixed by the thermocompression bondable films or the films with the adhesive.

摘要： PROBLEM TO BE SOLVED: To enable calculation which varies the value of a variable by registering variables by time and calculating the future value of the variable by a program. SOLUTION: An output part 7 directly accesses a storage part 1 for variable history to reads out the current value of the variable, and output it to outside the system, e.g. a display 3 on the basis of the value. Through the execution of an input part 8 and user programs 61 -6n controlling input from a mouse 4, a keyboard 5, etc., to the system, the variable is read out and updated through a time management part 2. The time management part 2 holds a time variable, and then performs management so that when the variable is read out, the value before the time of the time variable can not be read out and also adds and records the time of the time variable at the same time when the variable is varied. Thus, the history of the variable is stored and a new variable value is calculated according to the description declaring the relation between the past state and future state, and the progress of the calculation by declarative description is so controlled as the synchronize with the time of a actual clock.
