    • An identification level control method and an optical receiver are disclosed to determine an optimal identification level in a simple structure without clock extraction. In the identification level control method, an identification level supplied to a limiter amplifier is changed from a lower bound to an upper bound thereof and is stored together with an output average of the limiter amplifier. Then, a first average and a second average are set based on the output average. A first identification level corresponding to the first average and a second identification level corresponding to the second average are obtained, and an optimal identification level is computed based on the first identification level and the second identification level, and is supplied to the limiter amplifier.

    • A highly fashionable finger ring consisted of replaceable ring-shaped members is provided. A finger ring has ring-shaped members 1 and 2, each ring-shaped member 1 and 2 being decoupled in the center part, and between the both ends of a circular arc part 9(10), an opening 3(4) is produced by being twisted the both ends in a counter direction. Each end of the first ring-shaped member has the jewelry part 5 and 7 respectively, while each end of the second ring-shaped member having the jewelry part 6 and 8 respectively. The jewelry part 5(6) is relatively large, while the other jewelry part 7(8) being relatively small. Relatively large jewelry part 5(6) may be stereoscopic and large. When putting on a first and second ring-shaped member 1 and 2 in a manner opposed each other, a relatively large jewelry part 5(6) of either one of the two ring-shaped members fits in the opening 4(3) of the other ring-shaped member, seeming like one finger ring. Each ring-shaped member 1(2) is replaceable and can be combined extremely easily. Moreover, each ring-shaped member can be used individually.
    • 提供了由可替换的环形构件组成的高度时尚的指环。 指环具有环形构件1和2,每个环形构件1和2在中心部分分离,并且在圆弧部分9(10)的两端之间,产生开口3(4) 通过扭转相反方向的两端。 第一环形构件的每个端部分别具有首饰部分5和7,而第二环形构件的每个端部分别具有首饰部件6和8。 首饰部分5(6)相对较大,而其他首饰部件7(8)相对较小。 相对较大的首饰部件5(6)可能是立体的和大的。 当以彼此相对的方式放置在第一和第二环形构件1和2上时,两个环形构件中的任一个的相对较大的首饰部分5(6)装配在第二和第二环形构件1的开口4(3)中 其他环形构件,看起来像一个指环。 每个环形构件1(2)是可更换的并且可以非常容易地组合。 此外,每个环形构件可以单独使用。
