    摘要： A service AP conducting ordinary business processing is executed on a first OS. The first OS includes an operation recording controller for recording operation conducted by the first OS as operation recording information together with time when the operation is conducted, and an auxiliary driver for accepting and executing external processing. A multi-OS controller interface included in a second OS, which is higher in reliability than the first OS, operates a multi-OS controller from an AP operating on the second OS. An analysis and prediction AP operating on the second OS analyzes states of the first OS and the service AP, and detects a failure sign. Upon detecting a failure sign, degrade operation of the OS or service AP to be analyzed, preparations for switching from an active system to a stand-by system, and actual switching are conducted before the failure occurs.

    摘要： A computer system is structured, including a plurality of computers sharing a storage apparatus. The computers each include a control section for determining an access priority based on an attribute of a client computer forwarding an access request. In the control section, the result derived by adding up the priorities is compared with the total value of the priorities calculated by other computers for assignment of an input/output bandwidth. In accordance with the priority assignment, access execution is performed in order of priority. With such a structure, access congestions can be favorably avoided through efficient bandwidth control, and bandwidth assignment can be performed on a server basis in accordance with processes executed by the client computers.

    摘要： A charging device, an image forming apparatus including the charging device, an image carrier unit including the charging device and a charging roller, which faces a body to be charged and is applied with a voltage, are disclosed. The charging roller includes a metallic core and an elastic member covering the core. Films are respectively wrapped around and adhered to the opposite end portions of the elastic member. Springs press the charging roller toward a body to be charged, causing the elastic member to deform due to compression. The maximum deformation of the films, which deform along the outer periphery of the elastic member, is selected to be smaller than the thickness of each film in the radial direction of the charge roller. A gap is therefore formed between the elastic member and the body to be charged. This prevents the portion of the elastic member, which corresponds to an image forming region, other than opposite end portions from contacting the surface of the body to be charged.

    摘要： A method of controlling cache allocation to be executed by a server computer is arranged to realize resource management for securing a proper cache size. The server computer is arranged to have a memory unit and a CPU. The memory unit stores a memory allowable size of a memory to be secured as a disk cache by each of the programs to be executed by the server computer. In a case that a new disk cache is allocated to the memory unit when accessing a disk drive under the control of the program being executed, the CPU reads from the memory the memory allowable size corresponding with the program and allocates the disk cache to the memory unit so that the disk cache may stay in the range of the memory allowable size.

    摘要： An image forming apparatus including a plurality of image forming units or process units is disclosed. The process units may each be moved into and out of the body of the apparatus by hand. A plurality of support members for supporting the ends of the process units to be operated by hand extend substantially parallel to a linear path for conveying a recording medium, but outside of paths for moving the process units into and out of the apparatus body. A positioning mechanism positions the above end of the individual process unit relative to the support members. The positioning mechanism is implemented by holes formed in the support members, and pins studded on a positioning wall included in the individual process unit. The apparatus allows the process units to be positioned thereon accurately with a high mechanical strength, while allowing them to be mounted and dismounted with ease.
