摘要： PROBLEM TO BE SOLVED: To quickly transfer a large capacity of network data by eliminating a bottle neck being the speed of a disk device by storing only data whose access frequency is high, and abandoning data whose access frequency is low at the time of storing transfer data in a low speed storage device such as a disk. SOLUTION: Whether accessed data are already registered in an LRU (least recently used) for memory management or an LRU for disk management, or the accessed data are not registered in the LRU for memory management is checked, and any processing 5a, 6a, and 7a is operated. When the data which are already registered in the LRU for disk management, or the data which are not registered in the LRU for memory management are registered in the LRU for memory management, data overflow from a cache in the memory. Then, whether the data should be transferred to a cache area on the disk or abandoned is decided according to the number of times of access in a period when the data are present in the cache area in the memory without unconditionally moving the data to the cache area on the disk.

摘要： PURPOSE: To simplify the operation procedure of a computer by deciding a calculation processing means to be started up by a control means corresponding to a computer using history stored in a storage means. CONSTITUTION: An application to be started up next is estimated by an interface program 3. When the interface program 3 selects the application to be started up next corresponding to the operation history of a user stored in the operation history 3a, the user first performs work by a normal method such as the specification of a command or the like and the interface program 3 stores the work history in the operation history 3a at the time. When such an operation history 3a is present, the identification of the next operation when it is defined that the succeeding operation follows the operation history as well is made possible. For instance, when the contents of data are updated by a data base program, the updating of a table by a tabulation program is identified as the next operation. Further, the updating of the contents of sentences by a word processor is identified as the next operation.

摘要： PURPOSE:To efficiently and flexibly realize coupling between neurons only in a required part by growing a growable data transfer means based on local information like the gradient of a diffused coupling request signal to form coupling to itself or another neuron. CONSTITUTION:A coupling source neuron 110 grows a growable transfer line 121 in the direction of the density gradient of the coupling request signal to form coupling with a coupling destination neuron 101. After formation of this coupling, data is transferred from the coupling source neuron 110 to the coupling destination neuron 101, and this data is weighted by a synapse circuit 103 and is transferred to the coupling destination neuron 101. In parallel with this transfer, weight value held in the synapse circuit 103 is changed to desired value by learning. If it is judged that coupling unnecessary, for example, if the weight value is 0 or smaller. the coupling destination neuron 101 generates a coupling disconnection signal to retard the growable data transfer line.

摘要： PURPOSE: To realize a space layout which speeds up the retrieval of space data and is small in storage capacity by retrieving data on each body with data for retrieval consisting of small coordinate arrays which are arranged hierachically.
CONSTITUTION: The data for retrieval are constituted by combining a two-dimensional array containing address values in a computer memory as element with a data structure called normally as a list, and the main body of the list consists of body names and addresses of a next list body. When a body under a body a is retrieved, the retrieval data are used to register the names of bodies which are possibly under the body A as intermediate results. The coordinates (entered in space data) of the body A and information showing which coordinate area some array element corresponds (which can be calculated from the size of the array and the size of the original area) are used to decide whether some array element is under the body A or not. Then, it is recognized whether each body registered as intermediate result is present under the body a to attain the retrieval.

摘要： PURPOSE:To enable giving eye feeling of width by calculating automatically a reference line in the eye direction and that on a projected plane from the picture outer circumference position to specified one with respect to a picture of a three-dimensional shape displayed on a perspective and by displaying them. CONSTITUTION:A three-dimensional coordinate reader 9 outputs displaced data whose displacement in three three-dimensional independent directions is converted into a numeric to a data input device 8 to connect the data to an arithmetic processing device 4. While viewing a CRT screen, said reader 9 uses a three-dimensional coordinate input device with near-lever mechanism 3 which allows the displacement in the vertical direction and that in four directions to be that a picture in the eye direction and that in horizontal/vertical directions, respectively. A specification point of width is given to a perspective displayed on the CRT screen, and a locus up to the specification point on a projected plan is obtained and displayed on said plane. The locus consists of three straight lines, which are called a two-dimensional reference line. The reference line consists of the width displacement in the eye direction from a start point to the specified one, the vertical displacement and the horizontal one.
