    摘要： Provided is a bipolar battery that can achieve hermetic seal and mechanical strength in both and increase energy density. A bipolar lead acid battery (100) includes an outer wall (112), (122) integrally projected along a peripheral edge on a facing surface of one frame-plate (111), (121) out of frame-plates facing each other; and a joining wall (113), (133) integrally projected on a facing surface of the other frame-plate (111), (131) out of the frame-plates facing each other, the joining wall being positioned inwardly from the outer wall (112), (122) of the one frame-plate (111), (121) and surrounding a peripheral edge of a cell member (140) . The joining wall (113), (133) is joined to the facing surface of the one frame-plate (111), (121) via a joining material (151).

    摘要： Provided is an optical fiber ribbon and an optical fiber cable, which are adaptable to manufacture at a high velocity, in the intermittent connecting type optical fiber ribbon obtained by adhering and connecting adjacent colored optical fibers by intermittent connecting portions. In an optical fiber ribbon 2 of the present invention, since, in addition to polyol having a weight average molecular weight in a specific range, cellulose nanofiber is contained in a specific range in a material forming an intermittent connecting portion 3, the Newtonian region between a low shear rate region and a high shear rate region of the material forming the intermittent connecting portion 3 can be adjusted. Thus, scattering of the material due to a centrifugal force generated by rotation of an application roll that applies the material at the time of manufacture and the like can be suppressed, and the application amount to colored optical fiber 1 can be stabilized. In addition, the optical fiber ribbon 2 can maintain suppression of such scattering and the like even in the manufacture at a high linear velocity.

In an optical fiber ribbon 2 of the present invention, since, in addition to polyol having a weight average molecular weight in a specific range, rheology control agent is contained in a specific range in a material forming an intermittent connecting portion 3, the Newtonian region between a low shear rate region and a high shear rate region of the material forming the intermittent connecting portion 3 can be adjusted. Thus, scattering of the material due to a centrifugal force generated by rotation of an application roll that applies the material at the time of manufacture and the like can be suppressed, and the application amount to colored optical fiber 1 can be stabilized.

    摘要： The present invention relates to an optical fiber accommodated in an optical fiber cable, and more particularly, to an optical fiber which optimizes optical fiber coating resin and color resin and restrains an increase in transmission loss of the optical fiber due to an operating environment and aged deterioration and provides an optical fiber and optical fiber ribbon without any increase of transmission loss irrespective of the operating environment and aged deterioration, and especially when exposed to water or high humidity.
    The optical fiber is an optical fiber coated with at least two layers of coating resin, wherein the outermost coated coating resin is a colored layer made of color resin and when the optical fiber is immersed in water which is heated to 60°C for 168 hours, an extraction rate of the coating resin of the optical fiber is set to 1.5 mass percent or below.

    摘要翻译： 本发明涉及容纳在光纤电缆中的光纤，更具体地说，涉及一种优化光纤涂层树脂和着色树脂的光纤，并且抑制由于操作环境和老化而导致的光纤的传输损耗的增加 劣化，并且不管操作环境和老化劣化，特别是当暴露于水或高湿度时，提供光纤和光纤带，而不会增加传输损耗。 光纤是涂覆有至少两层涂布树脂的光纤，其中最外涂层涂层树脂是由彩色树脂制成的着色层，当光纤浸入加热至60℃168小时的水中时 ，将光纤的涂布树脂的提取率设定为1.5质量％以下。
