    • The code generation apparatus includes: a clock generator which generates a clock signal of a first frequency; a timing controller which generates a timing signal of a second frequency lower than the first frequency; a code table storage in which a plurality of code sequences serving as a source for a pseudo-noise code is stored; an address controller which selects, according to the timing signal, a code sequence to be read, from among a plurality of code sequences; a partial code sequence extractor which extracts, as a partial code sequence, a code of a predetermined length, from the code sequence to be read; and a parallel-series convertor which outputs the partial code sequence one bit at a time, according to the clock signal.
    • 代码生成装置包括:时钟发生器,其生成第一频率的时钟信号; 定时控制器,其生成低于第一频率的第二频率的定时信号; 其中存储用作伪噪声码的源的多个码序列的码表存储器; 地址控制器,根据所述定时信号,从多个码序列中选择要读取的码序列; 部分代码序列提取器,从要读取的代码序列中提取预定长度的代码作为部分代码序列; 以及并行串联转换器,其根据时钟信号一次输出一个位的部分代码序列。

    • A method for manufacturing a polishing pad that has high level of optical detection accuracy and is prevented from causing slurry leak from between the polishing region and the light-transmitting region includes preparing a cell-dispersed urethane composition by a mechanical foaming method; placing a light-transmitting region at a predetermined position on a face material or a belt conveyor, continuously discharging the cell-dispersed urethane composition onto part of the face material or the belt conveyor where the light-transmitting region is not placed; placing another face material or belt conveyor on the discharged cell-dispersed urethane composition; curing the cell-dispersed urethane composition to form a polishing region including a polyurethane foam, so that a polishing sheet is prepared; applying a coating composition containing an aliphatic and/or alicyclic polyisocyanate to one side of the polishing sheet and curing the coating composition to form water-impermeable film; and cutting the polishing sheet.
    • 制造具有高水平的光学检测精度并且防止在抛光区域和透光区域之间引起浆料泄漏的抛光垫的方法包括通过机械发泡法制备细胞分散的聚氨酯组合物; 将光透射区域放置在面材或带式输送机上的预定位置处,将细胞分散的聚氨酯组合物连续排出到未放置透光区域的面材或带式输送机的一部分上; 将另一种面材或带式输送机放置在排出的细胞分散的聚氨酯组合物上; 固化细胞分散的聚氨酯组合物以形成包括聚氨酯泡沫的抛光区域,从而制备抛光片; 将包含脂族和/或脂环族多异氰酸酯的涂料组合物施加到抛光片的一侧并固化涂料组合物以形成不透水膜; 并切割抛光片。
