摘要： An electrophotography system for use in laser printers, printing machines and copying machines. The system includes a rototable drum having a photosensitive member which can take a first absorption spectrum state and a second absorption spectrum state, the variation from the first absorption spectrum state to the second absorption spectrum state being made by illuminating it with light whose intensity is above a predetermined threshold and whose wavelength is in a first predetermined wavelength region. Also included is an optical system including a light-emitting device for illumination of the photosensitive member so as to form thereon an electrostatic latent image, the optical system being arranged to directly illuminate the photosensitive member with light from the light-emitting device and further to illuminate it with reflected light from an original picture. The light-emitting device is arranged to emit light whose wavelength is in the first predetermined wavelength region and further light whose wavelength is in a second predetermined wavelength region. A control unit performs one selected from a laser-printing mode, a printing mode and a copying mode so as to form the corresponding electrostatic latent image on the photosensitive member by lights which are different in intensity and wavelength from each other.

摘要： An information recording method and an information recording apparatus are disclosed, wherein x-bit long binary data are converted into m multi-level data of n levels (x is an integer equal to or greater than 3, m is an integer equal to or greater than 2, and n is an integer equal to or greater than 3). The x-bit long binary data are treated as a word, where two or more words constitute a row of data sequence. Two or more rows of data sequence constitute an error correction block, each row having address information attached. The multi-level data, to which the error correction block is added, are recorded in an information recording medium.

摘要： A method of recording data as presence/absence of marks on an information recording medium includes a step of obtaining data pieces, each of which has size of one block and is made by adding error-correction-purpose data to information data, a step of attaching to each of the data pieces a synchronizing signal that includes a portion having the marks and a portion having no mark, a step of recording the data pieces on the information recording medium in units of the one block inclusive of the synchronizing signal, and a step of placing a concatenation point at a predetermined position within the synchronizing signal when adding, or writing in an overwriting manner, the data pieces in units of the one block, the concatenation point defining a position at which said adding or said writing starts.

摘要： A mark representing information of a multivalued level is recorded in each of cells arranged in a recording medium. Upon reproducing the multivalued level from a reproduction signal of the recording medium, the multivalued level of a present cell is judged by referring to a judged multivalued level of a preceding cell preceding the present cell or an ensuing cell ensuing the present cell, or by referring to the judged multivalued levels of both the preceding cell and the ensuing cell.

摘要： A method of generating an efficient sequence of “nm+m−1” level random numbers, each sub-sequence of “m” successive random numbers thereof having a different pattern, including the steps of generating a sequence of n-level random numbers based on an initial value, a number being generated at a time, determining whether a pattern of a sub-sequence is “used”, if the pattern of the sub-sequence is “used”, setting a different value to the initial value, if the pattern of the sub-sequence is not “used”, accepting the newly generated number and marking the pattern as “used”. All of the steps are repeated until all of “nm” patterns are exhausted. Since the newly generated number is rejected if the pattern of the sub-sequence is “used”, the sequence becomes the shortest one of which all of “nm” patterns are exhausted.

摘要翻译： 一种产生“n”m + m-1“级别随机数的有效序列的方法，其具有不同模式的”m“个连续随机数的每个子序列包括以下步骤： 基于初始值的n级随机数的序列，一次生成的数，确定子序列的模式是否“被使用”，如果子序列的模式被“使用”，则设置 与初始值不同的值，如果子序列的模式不被“使用”，则接收新生成的数字并将模式标记为“已使用”。 重复所有步骤，直到所有“n”SUP“m”模式耗尽。 由于如果子序列的图案被“使用”，新生成的数字被拒绝，所以序列变成其中所有“n”个“”“模式被耗尽的最短的数字。
