    • A memory management and protection system for realizing a high speed execution and a proper and flexible memory access control for multiple programs sharing an identical logical address space. In the system, the memory access is permitted according to a segment identifier identifying a segment in the logical address space, and a memory protection information for a region in each segment including a target right permission to indicate assigned rights to make a memory access from the region to each of the segments, and an execution permission to indicate a type of the memory access permitted by the right permission. Alternatively, a memory access can be permitted by using an access control list to be attached to each address table entry, which stores a plurality of program numbers identifying programs which are permitted to make accesses to the logical address stored in each address table entry, among which one that matches with the current program number is to be searched. Also, it is preferable to allocate a plurality of programs within a limit of available memory protection capacity to an identical logical address space, without any overlap between adjacently allocated address regions.

    • A dot array fluorescent tube for an optical printer writes optical information on a photoconductive element by converting an information signal representative of a desired image to optical information. A grid electrode disposed in a vacuum space defined in a housing has a slot-like opening in a portion thereof which faces an array of fluorescent elements which are formed on anodes, which are also arranged in an array in the lengthwise direction of the housing. The grid electrode is formed as a metal film on the housing through an insulating layer. A conductive light intercepting film is deposited on the housing except for a limited portion which faces the fluorescent element array, thereby regulating the direction of light which is transmitted through the housing. The fluorescent elements in the array provide a plurality of dot arrays which are controlled independently of each other. Lead terminals are connected with the anodes and led out to the outside of the housing to be connected to external drive devices by an anisotropic conductive rubber connector. The lead terminals are divided into groups each made up of a predetermined number.
    • 用于光学打印机的点阵荧光管通过将表示所需图像的信息信号转换为光学信息将光信息写入光电元件。 设置在限定在壳体中的真空空间中的格栅电极在其一部分上具有槽状开口,该开口面对形成在阳极上的荧光元件阵列,该阳极也沿壳体的长度方向排列成阵列。 栅极通过绝缘层在壳体上形成为金属膜。 除了面对荧光元件阵列的有限部分外,导电遮光膜沉积在壳体上,从而调节透过壳体的光的方向。 阵列中的荧光元件提供了彼此独立地控制的多个点阵列。 引线端子与阳极连接并引出到壳体的外部,以通过各向异性导电橡胶连接器连接到外部驱动装置。 引线端子被分成由预定数量组成的组。

    • A decryption key management scheme for a software distribution system utilizing the decryption key, which can enable the re-install of the software that was decrypted once by a proper procedure, without requiring a re-acquisition of the decryption key from the software vender, so that a user can freely delete and re-install the software that was properly obtained once. The decryption key is searched in a memory device of a user's computer, or acquired from a distribution source of the encrypted software when the decryption key is not found in the memory means. Then, the encrypted software is decrypted by using the obtained decryption key, and a decrypted software content is installed into the memory device, while the decryption key acquired from the distribution source is stored into the memory device, such that the decryption key stored in the memory device is utilizable in decrypting the encrypted software at a time of re-installing the encrypted software.

Then, a data output is permitted when the identifier for identifying the program is not recorded in the protected data input record, while whether or not to permit a data output is judged according to at least a requested output target when the identifier for identifying the program is recorded in the protected data input record. For the writing data, the application program is authenticated, and the authentication result is stored in correspondence to an identifier for identifying the application program. Then, a request for access to writing data from the application program is permitted when the stored authentication result for the application program indicates a successful authentication for the application program.
