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.

A data input/output management scheme suitable for protection of electronic writing data. Whether the data entered into the program is a protected data or not is judged, and when it is, at least the identifier for identifying the program is recorded as the protected data input record. 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.
摘要:
A fire sensing system, a process for sensing a fire and an environment monitor are disclosed. The system includes infrared sensors with sensing wavelength bands sensing an infrared radiation from an infrared source. One of the sensing wavelength bands is a CO.sub.2 -molecular resonance radiation wavelength band. The system determines whether a disastrous fire occurs or not on the basis of outputs of the sensors and a change in a ratio of the outputs. The process computes the temperature of the infrared source from a ratio of outputs of infrared sensors with at least two sensing wavelength bands of an infrared radiation from a monitored area, produces the intensity of infrared radiation of either of the bands from the computed temperature and computes a heating area from the intensity and the output of a corresponding infrared sensor. The process determines the progress of a fire. The monitor produces a control signal to an air conditioner or room heater-and-cooler from outputs of sensors and an output of a thermometer.
