摘要： FP-4194-KS The present invention discloses a blast-furnace operation method which selects the oxygen volume in blast, the ore/ coke and the reducibility of the burden materials as control factors among various factors which participate in the variation of heat input and heat output of the blast furnace, which plots values of the three factors obtained from the practical operation on a graph consisting of three parallel axes to indicate the three factors, and which evaluates the conditions of furnace heat with reference to a balanced state of the three plotted factors to so control that the three factors will lie within a suitable range of the balance of the furnace heat.

摘要： PURPOSE: To prevent the progress of oxidation from a defect part by covering the surface of reduced iron with an organic film forming material. CONSTITUTION: The surface of the reduced iron is covered with the organic film forming material or a coating film containing the organic film forming material and a CO2 generating material to prevent the oxidation of the surface. The organic film forming material forms a homogeneous protective film free from defect even if it is thin compared to graphite or an inorganic material and enters even into many voids present in a sponge like reduced iron or the like to form a coating film on the wall surface thereof to effectively prevent the oxidation of the surface of the reduced iron. The organic film forming material is one or more kinds of hydrocarbon based materials selected from a group consisting of pitch, asphalt, coal tar, liquefied coal oil, and petroleum refining residue oil. As a result, excellent oxidation preventing effect is attained.

摘要： PURPOSE:To provide the artificial knee joint which satisfies the conditions of preventing excess expansion and preventing the pull-out of a thighbone side member and a tibia side member, engage both members with an allowance to obviate the generation of a failure and loosening by external force and stresses and is usable over a long period of time. CONSTITUTION:This artificial knee joint consists of the thighbone side member 10 and the tibia side member 20. A projection 22 is projectingly provided in the middle of the bearing surface 21b of the tibia side member 20 and a stopper surface 13A to be pressed to the projection is formed on the thighbone side member 10. On the other hand, the front side of the bearing surface 21b is so extended upward as to prevent the pull-out of the thighbone side member 10.

摘要： PURPOSE:To provide inplant members for displaying and maintaining a high fastening force by immersing a base material in slurry liquid having living active material powder dispersed in a medium, applying voltage to the base material as negative electrode, covering the surface of the base material with the living active material and baking the living active material after drying it. CONSTITUTION:To the surface of a base material 1 of a metallic inplant member is diffused and seamed fine granular or linear bodies formed of same kind of metal material, and a surface layer 2 having fine irregularities is formed on the surface 4 of the inplant member. Recesses 12 crash a living active material into pulverulent bodies which material is formed to widen from the uppermost surface to the innermost side, and provide slurry liquid 6 diffused in a medium. A vacuum pump 10 is operated to evacuate an upper space 5A and deaerate in the recesses 12 on the surface of the inplant member 4. The inplant member 4 is lowered and immersed in the slurry liquid 6 and voltage is applied between the inplant member 4 and an electrode 8 to charge the pulverulent bodies of living active material in the slurry liquid 6 to (+) and attract it to the surface of the inplant member 4 at the negative electrode side so that said pulverulent bodies are deposited on the innermost part 11 of the recess 12.

摘要： PURPOSE:To make the pore rate high and prevent easy removal from a base material by crushing inorganic porous matter having pores of 10-100mum into irregular grains and flame spraying them to the surface of the layer of the base material for diffused junction of the base material with the grains and the grains between each other. CONSTITUTION:For a material for forming a surface layer, porous matter of metal or ceramic is used. For the porous matter, material including many pores of 10-100mum and having a good compatibility with an organ is selected. One example is sponge titanium of a continuous bubble type. For forming the surface layer of a composite implantation member, the porous matter is crushed into irregular grains of about 100-400mum, and the grains are flame sprayed to the surface of a base material by plasma spray method for diffused junction of the base material with the grains or the grains between each other.

摘要： PURPOSE:To enable firm unification between a filler and a substrate material with strong bonding by making continuous pore, surface area and porosity respectively specified values. CONSTITUTION:CaHPO4 based-compound powder with >=5mum particle size and a binder are granulated using the rolling granulating method, etc., to prepare the primary particle with >=90% density and 30-200mum average diameter. CaHPO4 based-compound powder and a binder solution are then added to the resultant primary particle and the mixture is granulated using the rolling granulating method, etc., again to form the secondary particle consisting of a polynuclear particle having plural primary particles as the nucleus. The secondary particle is then subjected to addition of a binder and calcination after calcination or without more treatments to produce the objective formed material of CaHPO4 based compound with 30-50mum continuous pore, surface area larger than 10 times of the theoretical surface area and
