    • PURPOSE:To shorten the time required for injection and enable measurement of large flow rate by a method wherein the flow-channel-shaped separator having, at the upper end thereof, a pair of sharp and parallel edges having a fixed from of cross section is passed linearly across the flow of the downstream part of a fluid at a fixed speed, while the fluid passing through the separator is injected into the metering tank and the flow rate is measured from the quantity of injection and the time for injection. CONSTITUTION:The separator 4 composed of a pair of separating plates 41 and 42 having, at the upper end thereof, a pair of sharp and parallel edges 411 and 421 having a fixed form of cross section and of side plates 43 and 44 is moved at a fixed speed across the fluid from one side to the other side e of the downstream part 7 shown by broken lines by a moving device 5 consisting of a driving part 51 and a connecting rod 52. Only the fluid passing through the separator 4 is injected into the metering tank 6. The time of for injection can be detected by a mechanical, electrical or optical method. Accordingly, the flow rate is found by dividing the quantity of injection by the time for injection. By this, the time for injection is shortened and thus the measurement of large flow rate can be performed.

    • PURPOSE:To improve the performance of an associative memory and the degree of integration by calculating a Hamming distance between respective information in plural fields in inputted retrieval data and their corresponding self-completion information in each field and associating data having high similarity to the retrieval data in the ascending order of a total Hamming distance obtained by summing the Hamming distances of plural fields. CONSTITUTION:An associative memory operation means 1 stores self-completion information or mutual completion information corresponding to the self-completion information at the time of learning, and at the time of association, executes logical operation between retrieval data and the stored information. An inter-code distance calculating means 2 calculates an inter-code distance between incomplete information having amibiguity corresponding to the inter-code distance of the self-completion information and the self-completion information at the time of association. A decision means 3 activates the storing addresses of the incomplete information and the complete information having a small inter-code distance and a data associating means 4 applies the activated address information to a memory to associate data correspond to the self-associated or mutually associated complete information from the memory. Consequently, the performance can be improved and integration can be made easy.

    • PURPOSE:To obtain a high speed and high accuracy AD converter by quantizing an analog input, outputting a most significant order bit train, feeding-back the output of the analog integrator of that time to a selecting means, executing quantization to make the output the analog input newly, outputting the next high-order bit train and repeating an operation subsequently in the same way. CONSTITUTION:A bit number to be converted is divided into several blocks in advance. At first, the basic operation of a sigma/delta/AD conversion is executed by necessary number of times to the most significant bit train. Next, the output of an analog integrator 1 at the final time is made to the analog input of a selecting means 2 newly, and the basic operation is executed by the necessary number of times. Subsequently, the conversion of the bit train is executed in order from high-order. When the basic operations of (n) number of times are divided into the two blocks, first, the basic operations of (m) number of times are executed, and next, the basic operations of (n-m) number of times are executed with the output of the analog integrator 1 at a previous stage as the new analog input. In the case of b=1, n=128 and m=64, for instance, the AD converter of 7 bits can be realized in an existing system, and the A/D converter of 12 bits can be realized in this system.

    • PURPOSE:To attain the LU analysis of a spurse matrix with high efficiency by storing only the non-zero elements into a local memory of each local unit after ignoring the greater part of the zero elements of an original matrix Y to convert the matrix Y into a band matrix and flowing the elements successively in parallel and every line to (q) pieces of processors corresponding to the band width. CONSTITUTION:This processor contains (q) pieces of local units. Then, the local units 1-3 are all connected with each other via a common data bus 10, a control line 11, a priority circuit 12, etc. All non-zero elements only including the fill-in are stored in each local memory unit {Aj} in the row direction of a matrix after ignoring all zero elements. The operations of the processor are controlled in a division mode (a), a multiplication mode (b) and a gauss erasion mode (c) respectively. In the division mode the unit {Aj} receives an access by a counter 13. Only the local bus corresponding to a pivot aii is enabled by an enabling circuit 15. Then the pivot data aii are transferred to all local processors via a common bus.
