    摘要： A core 2 is co-doped with Ge in a general concentration equivalent to that in a core of an optical fiber to be connected as well as Sn and Al in predetermined concentrations. A glass part F including the core and a cladding 3 is coated with a primary coat layer 4 of a UV transmitting resin which transmits UV of 240 nm through 270 nm but cures by absorbing UV of a shorter wavelength band than 240 nm or a longer wavelength band than 270 nm. A grating is written in the core by irradiating the core with UV through the primary coat layer. The primary coat layer is covered with a secondary coat layer 7 of a resin having a negative coefficient of linear expansion so as to cancel and suppress expansion/shrinkage of the glass part in accordance with temperature change derived from the positive coefficient of linear expansion. Thus, the invention provides a fiber grating and a method of fabricating a fiber grating, in which a grating can be easily written without causing degradation of the transmitting characteristic, the transmitting characteristic and the mechanical strength characteristic can be consistent with each other without spoiling improvement of productivity, and the temperature characteristic can be stabilized for attaining high reliability.

    摘要翻译： 核心2与Ge共掺杂，其总体浓度相当于要连接的光纤的核心以及预定浓度的Sn和Al。 包括芯和包层3的玻璃部分F涂覆有UV透射树脂的初级涂层4，其透射240nm至270nm的UV，但通过吸收比240nm或更长波长的较短波长带的UV固化 带宽超过270nm。 通过用初级涂层UV照射核心，将光栅写入芯中。 初级涂层被具有负的线性膨胀系数的树脂的第二涂层7覆盖，从而根据从线性膨胀的正的系数导出的温度变化来消除和抑制玻璃部件的膨胀/收缩。 因此，本发明提供一种光纤光栅和光纤光栅的制造方法，其中光栅可以容易地写入而不会导致传输特性的劣化，传输特性和机械强度特性可以彼此一致而不会改善 的生产率，并且可以稳定温度特性以获得高可靠性。

    摘要： A structure for retaining an optical fiber, capable of not only handling a long optical fiber as one piece without causing the optical fiber as a whole to get loose but also reducing an area occupied by the optical fiber and retaining the same stably without causing micro-bending thereof to occur, wherein the optical fiber (1) is arranged so as to form planarly staggered turning portions thereof without causing intersecting parts to occur, a plurality of similar planarly staggered turning portions of the optical fiber being laminated in the same position in the direction of the thickness thereof which is at right angles to a plane on which the optical fiber is arranged, the resultant optical fiber (1) being generally retained in a sheet-like state by a fixing material (2), such as a bonding agent and a film.

    摘要： An optical fiber board has a substrate, optical fiber arranged as wiring on the substrate, and extension portions in each of which some optical fibers are led out from the substrate to be adjacent to each other in a row. The adjacent optical fibers at a base portion of the extension portion are not fixed to one another. The adjacent optical fibers at a forward end portion of the extension portion are fixed to one another integrally. The base portion has a predetermined length from an edge portion of the substrate.

    摘要： A blood-purifying regenerated cellulose membrane, in which the occurrence of the leukopenia phenomenon and the activation of the complement system are moderated, is prepared by applying a solution of a polymeric substance comprising as one component units derived from one or more basic vinyl monomers having an amino group in the side chain in an organic solvent to a regenerated cellulose membrane, removing the excessive solution, and then fixing the polymeric substance to the regenerated cellulose membrane.
