    • This invention relates to an oil cooler suitably applied to a hydraulic circuit for a power steering unit, and a method of manufacturing the same. The oil cooler according to the present invention consists of a tube bundle composed of a plurality of parallelly arranged tubes, volume chambers provided at both ends of the tube bundle, and a plurality of cooling fins fitted around the tubes, and is characterized in that it is made compact, has a high cooling capacity and a high torsional rigidity and can suppress the occurrence of noise. The method of manufacturing oil coolers according to the present invention is caracterized by comprising the steps of: (A) producing cooling fins by piercing in sheet materials to be worked into cooling fins a plurality of holes having axially projecting edges through which a plurality of tubes are to be inserted and further forming pores in the vicinity of the holes through which threadlike soldering material is to be inserted, (B) fitting the holes of the cooling fins around the tubes and inserting the soldering material through the pores of the cooling fins, and (C) melting the soldering material to bond the projecting edges of the cooling fins with the tubes. Thus an oil cooler can be manufactured simply at a low cost.

    • PROBLEM TO BE SOLVED: To surely perform quantization through parallel processing at high speed and to simplify a mounting circuit by decreasing the number of wirings by limiting coupling loads corresponding to respective cells to one kind and feeding only the difference between the value of sum of products and an input parameter amount back to respective cells. SOLUTION: When the amount of sum of products between the outputs and weight of respective cells is more than the input parameter amount, the cell outputting '+1' is operated so as to transit the state of its output to '0' or '1' and when the amount of sum of products is less than the input parameter amount, the cell outputting '0' or '-1' is operated so as to turn its output to '+1'. Namely, a dynamic quantizing means is provided for dynamically repeating the state transition of an output vector from the cell so as to minimize the differential amount. Then, a dynamic quantizer is dynamically operated so that the difference between a representative quantized value obtained by the sum of products between the outputs and weight of respective cells, and the input parameter amount can be converged within the level of hysteresis width and it is enough to feed only this difference back to respective cells.

    • PURPOSE:To attain learning and association processing based upon highly developed parallelism by providing the title computer with a learning processing means for storing associative patterns on a neural net and an association processing means for obtaining association by decoding an associative pattern into a linear graphic code formed at the time of learning processing. CONSTITUTION:For instance, a binary system for expressing the closed circuit of a graph forming each partial neural net 17 is allowed to correspond to a current code and error correcting capacity determined by a minimum inter-code distance is allowed to correspond to the capacity of ambiguity. At the time of learning processing, a sub-tree leaning input pattern is applied to a sub-tree 21 to be a part of the current code, a current code for a linear graph code is formed without generating a bit error and a tree current code to be the other part of the current code is stored in a tree in the partial neural nets 17 as a tree associative pattern. At the time of association processing, syndrome is calculated by addition using '2' as a modulo, a bit error is corrected and the syndrome is decoded to the current code formed at the time of learning to execute association. Thus, learning and association processing can be attained.
