    • An optical modulation method operable in an optical transmission path using an optical fiber, wherein an optical fiber bending region is formed by bending a portion of the optical fiber into a U shape having a predetermined bending width. A bending width set point is set in correspondence with a predetermined inclined portion of a characteristic curve representing a dependency ratio of insertion loss of light propagating in said optical fiber bending region relative to the bending width thereof, said predetermined inclined portion of said characteristic curve being located between a predetermined maximum and minimum portion thereof. Intensity modulation of light propagating in the optical fiber is performed using a signal to be transmitted by adjusting the bending width of the optical fiber bending region in correspondence with the signal to be transmitted with reference to the bending width set point as a center. An optical telephone uses an optical modulator including an optical fiber having a U-shaped bending region and a transducer for vibrating one straight portion of the optical fiber.
    • 一种光学调制方法,其在使用光纤的光传输路径中可操作,其中通过将所述光纤的一部分弯曲成具有预定弯曲宽度的U形形成光纤弯曲区域。 弯曲宽度设定点对应于表示在所述光纤弯曲区域中传播的光的插入损耗相对于其弯曲宽度的依赖比的特性曲线的预定倾斜部分,所述特征曲线的所述预定倾斜部分为 位于其预定的最大和最小部分之间。 通过以相对于弯曲宽度设定点为中心的要发送的信号调整光纤弯曲区域的弯曲宽度,通过使用要发送的信号来进行在光纤中传播的光的强度调制。 光电话机使用包括具有U形弯曲区域的光纤的光学调制器和用于振动光纤的一个直线部分的换能器。

    • A device and method for treating the end portion of a paper from a paper roll mounted on a paper feed unit of a paper processer. The device arranged adjacent the paper roll is moved toward the paper roll until a presser roller mounted on the device is pressed against it. A cutter assembly facing the paper roll is pushed out so that its cutter will come into contact with the periphery of the paper roll. The cutter is then slid transversely from one end of the paper roll to the other to cut several turns of paper from the paper roll as broke. The broke is rolled out to be fed downwardly over a suction body through a pair of nip rollers and taken up by a take-up mechanism. Another cutter assembly is pushed forward into contact with the central part of the paper end rolled out together with the broke and moved widthwise to make a center cut in the paper end. A cavity forming device is then pressed against the paper end right under the center cut to form a square cavity there. A tab sticking device carrying a tab is pressed against the paper end just over the cavity to stick the upper part of the tab thereon. Two knives for V-cutting arranged at both sides of the paper end are moved laterally toward its center, while rewinding the paper roll, to make a V-cut extending obliquely from both sides toward the cavity. Adhesive is applied to the paper end along the cut edge. The paper end is rewound on the paper roll. The tab adhered to the paper end is then pressed by the presser roller against the surface of the paper roll to be stuck thereto. The broke is then discharged from the take-up mechanism.
    • 一种用于从安装在纸张处理机的送纸单元上的纸卷处理纸张的端部的装置和方法。 布置在纸卷附近的装置朝向纸卷移动,直到安装在装置上的压辊被压靠在纸卷上。 面向纸卷的切割器组件被推出,使得其切割器将与纸卷的周边接触。 然后,切割器从纸卷的一端横向滑动到另一端,从而从纸卷上切下几圈纸。 这个断裂被推出,通过一对压辊将其向下提供到抽吸体上,并被卷取机构吸收。 另一个切割器组件被推向与纸张端部的中心部分一起与断裂一起滚动并沿宽度方向移动以在纸张端部中心切割。 然后将空腔形成装置压靠在中心切割下方的纸张端部,以在那里形成正方形腔。 携带突片的标签粘贴装置刚好在空腔上被压靠在纸张端上,以将突片的上部粘贴在其上。 在纸端两侧布置的两个V形切割刀横向朝其中心移动,同时重新卷绕纸卷,从而从两侧朝向腔体倾斜地形成V形切口。 粘合剂沿着切割边缘施加到纸张端。 纸卷在纸卷上倒卷。 然后将粘贴在纸张端部的突片通过压辊压靠在纸卷的表面上以贴在纸面上。 然后从卷取机构中排出。
