    • An optical fabrication method which is capable of adjusting a hardness and a density needed for each optical fabrication area in fabricating a three-dimensional fabricated article through sintering with a light beam, and is excellent in a working efficiency performs the steps of forming a powder layer of a predetermined thickness and then sintering the powder layer with a light beam, a predetermined number of times, cutting a periphery of the powder layers, and changing a degree of sintering by changing an amount of irradiation per unit area of a light-beam sintered surface according to a shortest distance from a peripheral surface of each powder layer.
    • 一种光学制造方法,其能够通过用光束烧结来调整制造三维制品的每个光学制造区域所需的硬度和密度,并且工作效率优异地执行以下步骤:形成粉末层 预定厚度,然后用光束烧结粉末层,预定次数,切割粉末层的周边,并且通过改变光束烧结单位面积的照射量来改变烧结程度 根据与每个粉末层的外周表面的最短距离的表面。

    • The first image which is a continuous image divided into pages is printed on the first surface of web by the first printer, and the start mark is printed at the head of each page. The second image which is a continuous image is printed on the second surface by the second printer in synchronization with recording synchronization pulses. In printing of the second image, obtained is a difference between the number of pulses inputted to the second printing mechanism between detections of preceding and succeeding start marks, and the number of pulses estimated to be inputted thereto in the case where expansion or shrinkage of web doesn't occur, to adjust the frequency of pulses on the basis of the difference. Therefore, the second image is printed in accordance with the first image on the web without being affected by expansion or shrinkage of web.
    • 作为分割成页的连续图像的第一图像由第一打印机印刷在纸幅的第一表面上,并且在每页的头部印刷起始标记。 作为连续图像的第二图像与记录同步脉冲同步地由第二打印机印刷在第二表面上。 在第二图像的打印中,获得的是在前后开始标记的检测之间输入到第二打印机构的脉冲数与估计输入的脉冲数之间的差异,在幅材的膨胀或收缩的情况下 不发生,根据差异来调整脉冲的频率。 因此,第二图像根据幅材上的第一图像而被印刷而不受幅材的膨胀或收缩的影响。
