Title: Method for producing three-dimensional article
Inventor: FURITSU BII PURINTSU
IPC: B22F3/115
Filed: 1993-01-29
Abstract: A method for forming a three-dimensional object by applying segments of complementary material and deposition material so as to form layers of material. Selected segments of material are then shaped after one or more segment is formed. In this manner, layers of material form a block containing the object made of deposition material and surrounded by complementary material. Then, the complementary material which serves as a support structure during forming is removed. Preferably, the complementary material has a lower melting temperature than the deposition material and is removed by heating the block. The deposition material and complementary material are preferably applied by thermal spray deposition but may be applied by weld deposition, liquid slurry, gravity drop or any manual means such as a hand sifter. It is also preferred but not necessary to use masks when applying the material. <IMAGE>

Abstract: PURPOSE:To improve the integration of a semiconductor device by forming a resistance layer on an insulating layer on the surface of a semiconductor substrate and concurrently matching and forming the resistance layer region with the same mask as a base layer region, thereby eliminating the error of matching the mask. CONSTITUTION:A silicon dioxide layer 9, a high purity polysilicon layer 10 and silicon nitride layer 11 are sequentially formed on an element region completing silicon substrate. Subsequently, a resistance layer of photoresist and a mask pattern of a base layer are formed by a photoprocessig step. The layer 11 is selectively etched to form a resistance layer mask pattern 12 and a base layer mask pattern 13 on the layer 10. Since the relative position of both the mask patterns is determined by the photoprocess in this case, it is accurate and the later steps do not require large mask allowance. Thus, the error of matching the masks can be reduced and the integration can be improved.

Abstract: PROBLEM TO BE SOLVED: To dissolve the problem on shortage of heat, decarbonization or agitation in a specified area, by letting a fused metal electromagnetically flow from the vicinity of an arc spot to the heat-shortage area. SOLUTION: This DC arc furnace is provided with a furnace top preheating chamber 2, in the furnace body 1, and it is constituted such that it preheats a metallic scrap 3 by discharging exhaust gas through the preheating chamber 2, and that it can effectively utilize the heat of exhaust gas. DC power where a furnace bottom electrode 4 is a plus pole is applied between a furnace bottom electrode 4 and a bar-shaped electrode 5. Power supply lines 7 and 8 supply the furnace bottom electrode 4 and the bar-shaped electrode 5 with power. Then, by a large current being let flow, an arc 9 is generated at the tip of the bar-shaped electrode 5, and the fused metal 6 is heated. Accordingly, an upward current is generated in the fused metal 6. Therefore, the fused metal in the vicinity of the arc carries heat to the heat shortage area 13, which accelerates the fusion of the metallic scrap 3 dropped and cast in from the furnace top preheating chamber 2.
