    • A pulling wire for tip articulation mechanism of endoscope is fitted with an overload preventing spring in the middle thereof. This spring is arranged to stretch upon more than a certain amount of tension. Elongation of the overload preventing spring absorbs any excessive tension which is exerted upon the pulling wire as a result of motion restriction of the endoscope. This spring is fabricated such that the material wire thereof is spirally coiled, and is simultaneously twisted so that forcing pressure is introduced in the spring in the direction in which the adjoining ring portions thereof are brought into pressure contact with one another it is subjected to tension.
    • 用于内窥镜的尖端关节运动机构的牵引线在其中部装有过载防止弹簧。 这个弹簧被安排在超过一定的张力下拉伸。 过载防止弹簧的伸长度由于内窥镜的运动限制而吸收施加在拉丝上的任何过大的张力。 该弹簧被制造成使得其材料线被螺旋卷绕并且同时扭转,使得迫使压力沿着相邻的环部彼此压力接触的方向被引入到弹簧中,其受到张力 。

    • An information recording and reproducing device diffracts by a diffracting means (14) to make laser light separated into a main beam and a sub-beam, irradiates evanescent light in relation to the main beam, by an evanescent light generating means (21), to a track where a recording pit provided on a recording surface of a recording medium is formed and also irradiates evanescent light in relation to the sub-beam to be separated to a track where no recording pit provided on the recording surface of the recording medium is formed. A moving means (210) moves the evanescent light generating means to a direction to change a gap with the recording surface. Further, a judging means (40) judges an uneven state of the recording pit formed on the recording medium, a signal generating means (3161) generates a gap error signal from a signal indicative of a return light amount in relation to the sub-beam or the main beam in accordance with the result, a control means (315) controls the moving means in accordance with a gap error signal so as to make the gap become a target value in response to the uneven state to be judged.
    • 信息记录和再现装置通过衍射装置(14)衍射,以使分离成主光束和子光束的激光相对于主光束相对于主光束照射消逝光,由ev逝光发生装置(21),以 形成记录介质的记录表面上的记录凹坑的轨道,并且还将相对于要分离的子光束的ev逝光照射到不形成记录介质的记录表面上的记录凹坑的轨道 。 移动装置(210)将瞬逝光发生装置移动到与记录表面改变间隙的方向。 此外,判断装置(40)判断在记录介质上形成的记录凹坑的不均匀状态,信号产生装置(3161)从表示相对于子光束的返回光量的信号产生间隙误差信号 或主光束,根据结果,控制装置(315)根据间隙误差信号控制移动装置,以使得间隙响应于待判断的不均匀状态而变为目标值。

    • A recording medium (100) is provided with: a first recording layer (L0) including a first area; and a second recording layer (L1) including a second area, wherein an edge on one side of the second area is located at a position obtained by shifting to an other side at least by a tolerance length from an area portion in the second recording layer corresponding to an edge on the one side of the first area, or an edge on the other side of the second area is located at a position obtained by shifting to the one side at least by the tolerance length from the area portion in said second recording layer corresponding to the edge on the one side of the first area, in which the tolerance length indicates an acceptable range of a relative position shift between an address which is defined on the predetermined position in the first recording layer and an address which is related to the predetermined position in the second recording layer.
    • 记录介质(100)具有:包括第一区域的第一记录层(L0) 以及包括第二区域的第二记录层(L1),其中第二区域的一侧上的边缘位于通过从第二记录层中的区域部分至少移动到公差长度而获得的位置 对应于第一区域的一侧上的边缘,或者第二区域的另一侧上的边缘位于通过从所述第二记录中的区域部分至少移动到一侧而获得的位置 对应于第一区域一侧的边缘的公差长度,其中公差长度指示在第一记录层中的预定位置上限定的地址与与第一区域相关的地址之间的相对位置偏移的可接受范围 在第二记录层中的预定位置。
