摘要： PURPOSE:To seal a gas or liquid cladding type optical fiber completely by bringing specific materials which are an input window and an output window for light into close contact with both the ends of a water-absorptive optical fiber and by sealing both the ends of a jacket with caps supporting the fiber and both the windows. CONSTITUTION:An input window 3a and an output window 3b for light are brought into close contact with both ends of an optical fiber 2, of CsI, CsBr, CsBrI, etc., where light ranging from the visible range to the infrared range is transmissible. The windows 3a and 3b are made of cylindrical or prismatic ZnSe single crystal, and the diameter of the input window 3a is equal to or less than that of the fiber 2. The diameter of the output window 3b is made greater than that of the fiber 2 to avoid light emission . Their close contact parts are supported in holes made in sealing materials (waterproof materials made of silicon or metal) to seal a jacket 1 completely. In the jacket, a gas or liquid 5 is sealed as a cladding material to prevent the water absorption and oxidation of the fiber. Thus, even a moisture- absorptive and poisonous optical fiber suitable for high-power transmission in usable in safety for a medical and a machining treatment.
摘要翻译：目的：通过将作为输入窗口的特定材料和用于光的输出窗口的特定材料与吸水性光纤的两端紧密接触并将两端的密封完全密封在气体或液体包覆型光纤上夹克与帽子支持纤维和两个窗户。构成：用于光的输入窗口3a和输出窗口3b与CsI，CsBr，CsBrI等的光纤2的两端紧密接触，其中从可见光范围到红外范围的光是可以传播的。窗口3a和3b由圆柱形或棱形ZnSe单晶制成，输入窗口3a的直径等于或小于光纤2的直径。输出窗口3b的直径大于光纤的直径 2避免发光。它们的紧密接触部分被支撑在由密封材料制成的孔（由硅或金属制成的防水材料）中，以完全密封护套1。在夹套中，将气体或液体5作为包覆材料密封，以防止纤维的吸水和氧化。因此，即使是适用于高功率传输的吸湿性有毒光纤，可用于医疗和机械加工处理的安全性。

摘要： PURPOSE:To decrease the penetration of water into optical fibers and reduce the effect of the time when the cable breaks, in the titled fiber unit, by forming a watertight metal film on the synthetic resin layers containing optical fiber strands therein. CONSTITUTION:A fiber unit 5 disposed within the optical cable is composed of synthetic resin layers 12, 13, etc. of silicon rubber, etc. covering optical fiber strands 1. A watertight metal film layer 14 of copper or silver is formed on the synthetic resin layers 12, 13 of this optical fiber unit 5, preferably by electroless plating, and if necessary, electroplating is further applied thereon to required thickness, on which a sheath 15 such as nylon is applied. A plurality of the obtained fiber strands are bundled by a sheath 9, whereby the optical fiber unit 5 is formed. Thereby, the moisture penetrating through the sheath of the cable is blocked with the metal film layer 14.

摘要： PURPOSE:To enable the continuous growth of single crystal at high speed, by communicating the melting part of a raw material with a die for growing a single crystal using a U-tube, and by making a steep temperature gradient at the solid-liquid interface between the melt introduced to the die and the single crystal. CONSTITUTION:The raw material 7 is dropped to make the melt level at the fixed position, and it is melted in the crucible 2 by the heater 1a. The heater 1a is eqipped with the lifting and lowering mechanism 10, and the melt level can be adjusted to any position based on the top of the die 4b by moving vertically the position of the heater 1a based on the melting part 2. The melt 5 is passed through the U-tube 8, the steep temperature gradient is produced by the temperature regulating means consisting of the cooler 9 and the heater 1c, the melt is transferred to the tip of the die 4b and converted into a single crystal. In the operation, the lowering speed Vd of the raw material 7 and the speed Vp of pulling up the single crystal are mainly regulated in such a way that the separating amount of the single crystal 6 is harmonized with the feed amount of the raw material 7.
