    • A method for bleaching teeth comprises steps of applying a solution containing nitrogen-deeped titanium oxide powder on a surface of teeth, and irradiating the applied part with light to bleach the teeth based on a photocatalytic action thus produced, and a bleaching agent for teeth suitable for carrying out the method comprises a solution containing nitrogen deeped titanium oxide powder, in which the nitrogen-deeped titanium oxide is preferably a photocatalytic substance having a Ti—O—N structure having a titanium oxide crystalline lattice containing nitrogen and exhibiting a photocatalytic action in a visible light region, the bleaching agent contains preferably 0.01 to 5% by weight of the nitrogen-deeped titanium oxide powder, the nitrogen-deeped titanium oxide powder has a specific surface area of from 10 to 500 m2/g, the solution contains water and/or an alcohol as a solvent, and the bleaching agent further contains preferably 0.5 to 20% by weight of a thickener, 1 to 20% by weight of hydrogen peroxide, and 2 to, 45% by weight of urea peroxide.
    • 漂白牙齿的方法包括以下步骤:将含氮深二氧化钛粉末的溶液涂在牙齿表面上,并根据所产生的光催化作用照射所施用的部分以漂白牙齿,并且适合用于牙齿的漂白剂 用于实施该方法的方法包括含氮深氧化钛粉末的溶液,其中氮 - 深二氧化钛优选是具有Ti-ON结构的光催化物质,其具有含氮的氧化钛晶格并且在可见光中显示出光催化作用 亮区,漂白剂含氮优选为0.01〜5重量%,氮深二氧化钛粉末的比表面积为10〜500μm2 / g,溶液含有水和/或醇作为溶剂,漂白剂还优选含有0.5〜20重量%的增稠剂,1〜2 0重量%的过氧化氢和2〜45重量%的过氧化脲。

    • An image processing system includes an image reader for reading image data of original documents, a memory which is capable of storing image data of the original documents of a plurality of pages read by the image reader and a detector for detecting insufficiency of empty capacity of the memory. A first controller executes a writing of a set of image data of the original documents of a plurality of pages into the memory in a prescribed page order, and repeatedly executes a reading of the set of image data from the memory and an image processing thereof. In the event that insufficiency of empty capacity of the memory is detected by the detector during the writing of image data into the memory by the first controller, a second controller holds the image data of the original documents of one or a plurality of pages stored in the memory and executes a subsequent image processing by using the image data held in the memory. A third controller executes a prescribed processing of a re-reading of image data of the original documents corresponding to the image data not held in the memory among the set of image data by the image reader in the subsequent image processing by the second controller.
    • 图像处理系统包括用于读取原始文档的图像数据的图像读取器,能够存储由图像读取器读取的多个页面的原始文档的图像数据的存储器和用于检测图像读取器的空容量不足的检测器 记忆。 第一控制器以规定的页面顺序执行多页的原始文档的一组图像数据的写入到存储器中,并且从存储器重复执行该图像数据的读取及其图像处理。 在由第一控制器将图像数据写入存储器期间由检测器检测到存储器的空容量不足的情况下,第二控制器保存存储在存储器中的一页或多页的原始文档的图像数据 存储器并且通过使用保存在存储器中的图像数据来执行后续图像处理。 第三控制器在由第二控制器进行的后续图像处理中执行由图像读取器在图像数据集合中对应于未保存在存储器中的图像数据的原始文档的图像数据的重新读取的规定处理。
