摘要： PURPOSE:To enable the movement of an elbow position in any finger position- attitude area by determining a control parameter according to whether the position and attitude of the fingers are within the range of the command value on a redundant parameter on the basis of the command value on the finger position and attitude, and performing the inverse coordinate conversion of each joint angle at real time. CONSTITUTION:The joint angle of an articulated arm 1 with seven freedom or more formed of rotary joints is controlled by each shaft control part 2. Such a manipulator control device is additionally provided with an inverse coordinate converting part 3. On the basis of the command value on the position and attitude of the fingers, the inverse coordinate converting part 3 determines a control parameter according to whether the position and attitude are within the range of the command value on a redundant parameter and performs the inverse coordinate conversion of each joint angle at real time using this control parameter. The redundant freedom of a manipulator is thereby controlled by off-line or on-line without being limited by the position and attitude of the fingers.

摘要： PROBLEM TO BE SOLVED: To obtain an address converter which is effective to information processing that is needed for real time by switching a conversion table cache to a conversion table cache which corresponds to new context. SOLUTION: Plural page conversion table caches 13 are switched by a switch 14 according to the value of a context register 12 so that the page conversion table cache for context which is currently processed by a CPU can be used. However, when a page conversion table cache for a context that is about to be processed by the CPU does not exist, it switches to a conversion table cache that has the oldest final reference time among final reference times which are finally referred to by each page conversion table cache respectively. Thus, it switches to a page conversion table cache which is provided with plural caches 13 and corresponds to context that is about to be processed by the CPU.

摘要： PROBLEM TO BE SOLVED: To provide a method for a system response or system resource utilization suitable for respective users having different levels. SOLUTION: The operating action of a user is measured through an input device 11, applied through an input control part 12 to an operating action recording part 13, recorded and stored in an operation history data base 14. A feature extracting part 15 extracts the action feature of the user from stored data for each feature amount. Based on the extracted feature amount, a level estimating part 16 discriminates the level of the user while utilizing knowledge in a skilfulness knowledge base 17. A response inferring part 18 decides the suitable response method while utilizing domain knowledge in a domain knowledge base 19. According to the decided response method, a response content generating part 1a generates an actual response and displays it through an output control part 1b onto a display device 1c. According to the decided response method, a function control part 1d provides a system function suitable for the level of the user.
