摘要： In an image forming machine, an objective model storage device stores parameter data that represent elements of the machine and relationships among such parameters, and parameter membership functions, and fault diagnosis knowledge. A degradation storage device stores a fuzzy qualitative value for a parameter changed by degradation of an element of the machine. Preferably, degradation indicative data are converted into fuzzy qualitative values, and the value of the parameter changed by degradation is represented by a fuzzy qualitative value. The machine includes sensors for sensing functional states thereof, and providing state data representative of such states. The state data sensed by the sensors are converted into fuzzy qualitative values. Then, a fault judgement device determines whether or not a fault exists by comparing the obtained fuzzy qualitative values with the parameter data stored in the objective model storage device. If the fault judgement device determines that a fault exists, a fault diagnosis device performs fault diagnosis by utilizing, as an initial value, the value of the parameter changed by degradation. A specification device specifies fault causes by comparing the result of the diagnosis with the state data which was converted into the fuzzy qualitative values. Then, a repair device operates actuators of the machine to overcome the specified fault.

摘要： A system according to the invention has a plurality of sensors, a system control circuit and a plurality of actuators. State data, supplied from the sensors, is compared with characteristic data in the system control circuit. From this comparison, it is judged whether a fault has occurred depending upon whether the state data is relatively lower or higher. If a fault has occurred, fault inference fault is made on the basis of a comparison between qualitative data and fault diagnosis knowledge which are stored in the system control circuit. Then a judgement is made as to which of the elements in an image forming apparatus is abnormal. An actuator operating signal thereafter is generated as a result of this judgement.

摘要： The present invention makes it possible to make good self-repair on which little secondary effect is exerted by calculating a manipulated variable of a parameter at the time of the repair by a functional amount in an image forming apparatus having a self-repair function. When a fault occurs, control-type repair for operating a physical parameter is first made. In this repair, the physical parameter to be operated is searched for (n3). If the physical parameter to be operated is determined, a manipulated variable of the physical parameter is then calculated by a functional amount (n4). The manipulated variable of the parameter by the functional amount is determined by adjusting the degree to which a plurality of functions are developed. Therefore, a manipulated variable in which the development of the functions is most preferable as the entire apparatus is determined. If the fault cannot be repaired by the control type repair, functional redundancy type repair is made (n6, n7, n8, n9). In the functional redundancy type repair, priorities to repair candidates are determined by the functional amount.

摘要： A method of automatically creating control sequence software required for a machine system controlled by a computer includes four algorithms, that is, "derivation of control sequence specification".fwdarw."derivation of a qualitative control sequence".fwdarw."addition of quantitative information (derivation of a quantitative control sequence)".fwdarw."generation of a C program". The qualitative control sequence is a state transition matrix following the time sequence. This qualitative control sequence is derived by making use of a qualitative inference system. A quantitative control sequence is obtained by adding quantitative time between states to the qualitative control sequence. Time information is calculated on the basis of design information of a machine portion stored in a design information database. As a result, it is possible to reduce the manual burden on the software development by using the present invention.

摘要： A so-called "softly broken apparatus" by constructing a self-repair apparatus based on functional redundancy. An apparatus is represented in a form including a function using an FBS diagram (a diagram comprising functions, behaviors and states). When a fault occurs, a function lost is retrieved by the FBS diagram, and a functional part capable of developing the lost function by a potential function is detected. The potential function of the functional part is developed, thereby to recover the lost function. Specifically, when a fault occurs in an apparatus, a lost function is recovered by utilizing a part which originally exists in the apparatus by utilizing the existing part as a substitute for the part which fails.

摘要： According to the present invention, a self-diagnosis system for an image forming apparatus can make accurate fault diagnosis and is made smaller in size and higher in speed. For that purpose, a fault temporarily developed by the image forming apparatus is limited to a single fault assumption, all states which can exist on the image forming apparatus when the image forming apparatus develops the fault are previously simulated, and the results of the qualitative simulation are stored as a plurality of virtual cases in a virtual case storing portion 12. When the image forming apparatus is operated, detected values of sensors X, Vs and Ds are converted into fuzzy qualitative values, respectively, on the basis of membership functions stored in a membership function generating portion 13. The fuzzy qualitative values are compared with the virtual cases stored in the virtual case storing portion 12, to reason the cause of the fault. Accordingly, any of the virtual cases stored in the virtual case storing portion 12 is selected using the fuzzy qualitative values, thereby to make it possible to accurately specify the fault in a short time.

摘要： A simulation system is provided which is capable of simulating the behavior of a sheet transported by a transportation system. In response to application of a control sequence formulated for the sheet transportation system, a simulation is performed to check how the sheet is to be transported in the sheet transportation system on the basis of the applied control sequence. Necessary data are extracted from hardware systems constituting the real sheet transportation system. On the basis of the extracted data, a virtual sheet transportation system is constructed in a computer, and the sheet is represented by information indicative of the locations of opposite ends of the sheet and the distance therebetween. The sheet thus represented is moved by a predetermined unit distance in the virtual sheet transportation system on the basis of the control sequence, and data is computed for every movement of the sheet.

摘要： A working method for wire drawing, applicable even to alloys such as Au--Sn and Au--Si which are fragile and which have their tensile strengths lowered rapidly when heated. A die and wire to-be-pulled are heated by a heating device so as to increase the ductility of the wire. On the other hand, finished wire having just been pulled out of the die is cooled by a cooling device so as to increase the tensile strength of the wire. Thus, the wire material can be easily worked owing to the increased ductility, while it can be prevented from breaking after the working, owing to the increased tensile strength based on the immediate cooling. Accordingly, the wire drawing works of the Au--Sn alloy etc. are permitted.
