    • An optical fiber ribbon with a double layer structure comprising a first ribbon formed by bundling optical fibers using a first ribbon layer and a second ribbon formed by bundling the first ribbons using a second ribbon layer is described and claimed. The first ribbon layer is produced by curing a curable liquid resin composition, Composition 1, comprising: (Al) a urethane (meth)acrylate having a bisphenol structure; (A2) si urethane (meth)acrylate obtained by reacting an aliphatic polyather polyol, a polyisocyanate, and a hydroxyl group-containing (meth)acrylate; (B) a compound having a bisphenol structure and an ethylenically unsaturated group; and (C) a compound having an ethylenically unsaturated group other than the components (Al), (A2), and (B). The second ribbon layer is produced by curing a curable liquid resin composition, Composition 2, comprising: (D) 30 to '90 mass% of a urethane (meth)acrylate having a structure derived from polypropylene glycol with a number average molecular weight determined by gel permeation chromatography of 400 to 1,000; (E) 1 to 70 mass% of a compound having an ethylenically unsaturated group; (F) 0.1 to 10 mass% of a polymerization initiator; and (G) 1 to 50 mass% of a silicone compound with an average molecular weight of 1,500 to 35,000; wherein 50 to 100 mass% of the component (E) is a compound having two or more ethylenically unsaturated groups.

    • A code plate (1) is attached to the shaft of an object to be detected. The rotation of this plate is detected to generate one-turn signals and increment signals representing a fraction of rotation, formed by equally dividing one turn. The absolute position is measured by use of an ecoder having a counter (15) which counts the incremental signals. The counter (15) is cleared by the first one-turn signal (Z) generated after the encoder starts to operate. After the counter (15) is cleared, it counts up incremental signals with the rotation of the shaft of the object. However, the counter (15) is not cleared by the one-turn signals other than the first one. In this way, the counter (15) provides a value corresponding to the distance between the position where a one-turn signal is received and the position to be measured.
    • 编码板(1)附着到待检测物体的轴上。 检测该板的旋转以产生单匝信号和表示通过等分一匝形成的旋转分数的递增信号。 通过使用具有对增量信号进行计数的计数器(15)的解码器来测量绝对位置。 计数器(15)由编码器开始工作后产生的第一个单匝信号(Z)清除。 计数器(15)清零后,会随着物体轴的旋转而计数增量信号。 然而,计数器(15)不被除第一个之外的单匝信号清除。 以这种方式,计数器(15)提供对应于接收单匝信号的位置与要测量的位置之间的距离的值。
