PURPOSE:To easily bind an optical fiber flux for image transmission, consisting of silica compound glass, with high accuracy, by means of high-frequency induction heating. CONSTITUTION:A beltlike fiber aggregate is formed, by winding it up to an array drum, applying an adhesive agent thinly on a prescribed part, binding it temporarily and after that, cutting it off, it is piled on a forming jig 4 made of graphite, whose section is recessed, is stored, on which a cover body 5 made of graphite is placed, and pressure is put in the direction as indicated with an arrow A. A high- frequency induction coil 6 is placed in the outside circumference of the forming jig 4 containing the cover body 5, high frequency power is applied, and when induction heating is executed to a high temperature, end parts of the optical fiber flux are heated, are made to adhere to each other, and are formed in one body. In order to prevent thermal oxidation of the forming jig, it is executed in the atmosphere of inert gas such as gaseous nitrogen, etx. This method is especially suitable for manufacture of a heat resistance optical fiber flux for observing a high heating part, etc. of various high heating apparatuses, etc. |
