摘要： PURPOSE:To uniformly provide a squalane fixed phase on the inner face of a silica capillary by giving silile treatment to the inner face of the silica capillary with octadecyldimethyltoxisilane and applying squalane thereto. CONSTITUTION:A silica capillary 1 which is coated with a 10mum thick polyimide protective film 4 is cut at a length of 60cm, on the inner face of which a thin film is formed by using a dynamic technique with octadecyldimethyltoxisilane. The capillary 1 with both ends sealed is heated to 400 deg.C to react an OH radical on the inner face of silica glass sufficiently with octadecyldimethyltoxisilane, an excess of which is then removed with methylene chloride. In this way, an octadecyldimethyltoxisilane surface treatment layer 2 is given to the inner face of the capillary 1. Next, 0.4w% solution in n-pentane of squalane is filled in the silile-treated capillary 1, and solvent n-pentane is removed by using a static technique to form a squalane fixed phase 3 of thickness 0.30mum.

摘要： PURPOSE:To obtain the optical fiber having high strength and good heat resistance by applying an org. metal polymer on a quartz fiber and backing this polymer, then applying a filler-contg. org. metal polymer thereon and baking this polymer. CONSTITUTION:The quartz fiber 3 from an optical fiber base material 2 obtd. by heating and melting in a drawing furnace 1 is first sent to a 1st cup where the org. metal polymer; for example, polytitano carbosilane, is applied thereon. The fiber is then sent to a 1st baking furnace 5 where the fiber is baked and the org. metal polymer is primarily clad on the surface of the fiber 3. The fiber coated with this org. metal polymer is successively passed through a 2nd cup 6 and a 2nd baking furnace 7 where the filler-contg. org. metal polymer and zirconia-contg. polytitano carbosilane are applied thereon and are baked. The two-layered coatings of the heat resistant resins are applied on the fiber 3.

摘要： PURPOSE:To easily peel a coating material from a glass optical fiber and to facilitate connection or terminal processing work by interposing an organometal compound which adds the property of peeling at a boundary between a glass and the jacket material. CONSTITUTION:In this heat resistant optical fiber coated with the jacket material made of organometal polymer composition, the organometal compound which adds the property of peeling from the glass is interposed at the boundary between the glass constituting a fiber and the jacket material, so that the jacket material is easily removed. The organometal polymer has repeating units including at least one or more metals in a molecule and also has at least one or more three-dimensional structural unit as well as an organic group before curing. Thus, the jacket material is easily removed by the terminal processing of the optical fiber or connecting work thereof, and the workability is improved.

摘要： PURPOSE:To produce the quartz capillary column having a high resolving power at a high speed by packing a soln. of a stationary phase forming material into a quartz capillary, then bringing the liquid of the temp. higher than the evaporation temp. of a solvent into contact with the outer side of the quartz capillary to heat the capillary. CONSTITUTION:For example, a 0.4% methylene chloride soln. of polydimethyl siloxane is packed into the quartz capillary 2 coated with a heat resistant resin on the outside surface. The quartz capillary 2 packed with the liquid 3 is fed at a speed of about 5m per hour to a heating section 4 form a delivery device 1. The capillary 2 passes the inside of a heat medium 5 in the heating section 4. Water is used for the heat medium 5 and is kept at about 80 deg.C. Methylene chloride which is the solvent evaporates from the polydimethyl siloxane soln. 3 in the capillary 2 heated from the circumference by the heat medium 5 and the thin film 32 of the polydimethyl siloxzne is formed in the capillary 2. The evaporation temp. of the methylene chloride is 40 deg.C and the temp. of the heat medium 5 is higher than this temp. The quartz capillary 2 formed with the fixed phase 32 is taken upon a take-up unit 6 in a thermostatic chamber 7.

摘要： PURPOSE:To obtain an optical fiber sensor which is sensitive to temperature and pressure without special apparatus for coating by using a shape memory resin as a coating material for optical fiber. CONSTITUTION:A shape memory resin is used as a coating material for optical fiber. The shape memory resin is hardened at temperature lower than a specified temperature and protects the optical fiber against side pressure. The resin is softened at temperature higher than a specified temperature and becomes sensitive against the side pressure. When deformation larger than a specified value is imparted, the deformed state remains at temperature lower than a specified temperature. When the specified temperature is exceeded, the shape returns to the shape before the deformation. When residual strain in the tensile direction is imparted to the coating material beforehand, the strain is released at first when the material is heated to the temperature higher than the specified temperature. The side pressure is momentarily applied to the fiber by the contraction at this time. The transmission loss in the optical fiber is rapidly increased. Since the temperature increase can be detected by monitoring, this sensor is effective as a temperature sensor.

摘要： PURPOSE:To improve dimensional precision and reliability of an optical connector by using a nonshrinkable resin for a material. CONSTITUTION:A fundamental constituting part of the title connector is constituted of a nonshrinkable resin, for which a spiro orthoester type resin or a bicyclo orthoester type resin is most suitable. By using such resin, the degree of shrinkage can be lessened remarkably as compared to an optical connector constituted of an epoxy resin, and wraps and strains due to shrinkage during setting are not generated, and deterioration of characteristics due to deterioration of dimensions accompanying generation of microcracks is eliminated. Its internal stress is reduced and the reliability of the connector is improved remarkably since it is no more necessary to reduce the shrinkage in the stage of setting by using a filler.

摘要： PURPOSE:To improve tensile strength and moisture resistance by using a cured fluoroacrylate resin as a coating material on the outside circumference of a glass fiber which allows transmission of IR rays. CONSTITUTION:A glass base material consisting of fluoride glass is held in a drawing furnace in which an inert atmosphere is maintained and the temp. is kept at 400 deg.C. Gaseous He of about 4kg/cm is pressurized on the glass tube from above and the glass tube is drawn to 200mum outside diameter. The drawn fiber is passed through a die cup in which a UV curing type compsn. essentially consisting of carbonate acrylate formed from tetrafluoropropyldiol to constitute a clad is packed, by which said compsn. is coated on the fiber to 250mum outside diameter. The coating is cured by a UV curing device. The tensile strength of the formed optical fiber is 5kg in average. The strength and moisture resistance are thereby improved.
