Title: Refining method for molten steel
Inventor: IKEHARA YASUMASA
IPC: C21C5/28
Filed: 1981-11-17
Abstract: PURPOSE:To progress the transfer of the oxygen in the metallic oxides in slag to  molten steel positively and to perform decarburization and reduction simultaneously by  ceasing the decarburization by blowing of O2 or an O2-contg. gas halfway, charging a  part of reducing agents and refining the molten steel to a half reduced state. CONSTITUTION:After decarburization by blowing of O2 or an O2-contg. gas is ceased  between the final value of C or over and <=0.15% concn. of C in molten steel, only the  insert gas is blown into the molten steel. At this same instant, reducing agents are  charged until the metallic oxides of the amt. necessary for decarburization remain in  slag, whereby decarburization and reduction are accomplished simultaneously. Even if  the blowing of O2 is ceased after the C in the molten steel is removed down to <=0.15%,  the C in the molten steel is removed by the O in the molten steel simply by diluting  the inert gas. The O in the molten steel is decreased by such decarburization, and if the  O in the slag transfers into the molten steel, the metalic oxides in the slag are reduced. However, this transfer is extremely small with blowing of only the insert gas and the fluidity of the slag is improved by the simultaneous charging of the reducing  agents, whereby the above-described transfer of the O is made positive and the reduction and decarburization are markedly progressed.

Title: Joint welding method by diffusion welding
Inventor: FUKAYA YASUHIRO
IPC: B21B15/00
Filed: 1981-11-19
Abstract: PURPOSE:To execute very easily diffusion welding in the longitudinal butt direction of  a thin plate long material, very easily, by constituting each welding surface of a material to be welded of an uneven engaged structure, and also providing a step difference. CONSTITUTION:Each welding surface 3 of materials to be welded 1, 2 is constituted of  an uneven engaged structure, and also is worked so that a step difference 5 is provided on each surface in the engaged state. They are heated to a necessary temperature  in this state shown in the figure, are pressed from the direction as indicated with an  arrow 4 until the step difference 5 is plastically deformed and is annihilated, and the  junction is completed. In this case, as for a part positioned at a right angle with the  direction 4, pressure to be loaded is transferred as it is, and as for an inclined part, component of force of the pressure force is transferred in accordance with the inclination. Also, as for a part whose junction surface is positioned in the same direction as  the direction 4, the pressure force is not transferred in itself and junction is impossible,  but due to compression plastic deformation of the step difference 5 part, a metal of its  part flows into the uneven part engaged with each other, and pressure force in the  lateral direction is generated. Accordingly, a part positioned in the same direction as  the direction 4 can be junctioned, too.

Title: Learning data contracting method for neural network
Inventor: HAYASHI MASAAKI
IPC: G06F15/18
Filed: 1993-07-27
Abstract: PURPOSE:To reduce the size of learning data without deteriorating a recognition rate of a neural network by using a distance function based on a statistic and a topology so as to make clustering. CONSTITUTION:All sample data S0 are used for input data in the step 1, the data are learned by a neural network in the step 2 to obtain a recognition rate R0 of test data. Then clustering processing (S11, S12) is conducted by using equation sigmaw(S11)>=sigmaw(S12).S11=S0-S12=S0/2 in the step 3, and the group S11 is learned/tested again in the step 4. Then a recognition rate R1 in the test data is compared with the initial recognition rate R0 in the step 5 and clustering processing loop is repeated till a recognition rate Rn is less than the initial recognition rate R0. A final group Sn-1 is a group at (N-1) number of times. Thus, the recognition rate of the test data is used for an evaluation criterion and necessary and sufficient sub groups are selected by using a multivariate and topological distance to obtain learning sample data.

Title: Cold thermal energy storing system
Inventor: FUJIMOTO MASAHISA
IPC: F24F5/00
Filed: 1986-08-08
Abstract: PURPOSE:To store a large quantity of cold thermal energy in a heat accumulating tank by suspending a container filled with water in the heat accumulating tank filled with antifreeze liquid and immersing a vaporizer of a freezer in the antifreezing liquid. CONSTITUTION:Refrigerant gas delivered by a compressor 2 is condensed by a condenser 3, and cools antifreezing liquid in a vaporizer 10 after going through an adiabtic expansion in an expansion valve 5. As the antifreeze liquid cooled in the vaporizer 10 descends through gaps between containers 11 and circulates in a heat accumulating tank 1 by convection, water in the container 11 is efficiently cooled and all of it become frozen to store cold thermal energy in the heat accumulating tank 1. In order to recover said cold thermal energy, a brine pump is operated. The antifreezing liquid is drawn by the brine pump 6 to enter a radiator 9 where it is heated by releasing the heat and returns to the upper part of the heat accumulating tank 1. As the ice in the container 11 is positioned higher due to a difference in the specific gravity from water, the temperature difference from the circulated antifeezing liquid becomes greater, thereby improving the heat exchanging efficiency.
