Title: Decomposition of rare earth ore
Inventor: OKABE TAIJIRO
IPC: C01F17/00
Filed: 1987-03-02
Abstract: PURPOSE:To enable the melt treatment of a rare earth ore near the melting point of caustic alkali and the decomposition of a rare earth ore irrespective of the material of the reactor, by carrying out alkali metal decomposition of a rare earth ore with caustic alkali in the presence of an oxidizing agent. CONSTITUTION:A rare earth ore is subjected to molten alkali decomposition with caustic alkali in the presence of an oxidizing agent. Any ore containing rare earth elements in an industrially valuable amount may be used as the rare earth ore in the present process, however, the ore is usually selected from concentrates of monazite, bastnaesite, xenotime and their mixture. The caustic alkali is caustic soda or caustic potash, among which inexpensive caustic soda is preferable for industrial use. The weight ratio of the caustic alkali to the ore is about 2-10 to proceed the decomposition while keeping the fluidized state of the reaction. The oxidizing agent used in the process is preferably oxygen, an oxygen-containing gas, inexpensive alkali nitrate or alkali nitrite.

Abstract: PURPOSE:To control automatically a rotation of a motor in accordance with a position of an object by constituting a titled device so that a present position detecting means always detects a position of the object, a direction determining means determines a rotating direction of the motor, based on this position signal, and the motor is brought to a rotation control by a rotation control means. CONSTITUTION:A present position detecting means 9 consisting of an encoder for detecting the present position of an object A and outputting a position signal detects the present position of an object 4 by detecting a rotation of a pulley 10 which is rotated by a belt 3. An input unit 11 receives a position signal from this present position detecting means 9 and converts it to a signal which can be controlled easily. A control means 12 measures the present position of an AC motor 1 from the converted position signal from this input unit 11, determines a rotating direction of the AC motor 1 by this present position, and also outputs a rotation control signal of the AC motor 1 in order to execute the acceleration, constant speed, deceleration and stop of the object 4. In this way, the rotating direction is determined by comparing a signal based on the present position and a signal based on a target point, and the rotating direction can be determined automatically.

Title: Casting method of product provided with vane part
Inventor: SASAKI YOSHIO
IPC: B22C9/28
Filed: 1984-03-10
Abstract: PURPOSE:To prevent generation of casting defects such as central shrinkage cavity, etc. and to obtain a defectless product provided with a vane part by using a composite casting mold consisting of a die for forming the outside peripheral part of a casting and a refractory casting mold for forming the vane part and boss part in performing vertical centrifugal casting. CONSTITUTION:Vertical centrifugal casting is performed by using a die 1 having large cooling power for forming the outermost peripheral part of a casting, for example, the outside periphery of the shroud part 3c of an impeller for a pump and a refractory casting mold 2 having small cooling power for forming a vane part 3b and boss part 3a. The cooling of the molten metal 3 in the vane part 3b and boss 3a is thus retarded. The generation of casting defects such as central shrinkage cavity or the like in the vane part 3b is prevented by such directional solidification. The inclusions in the molten metal further centrifugally separated by centrifugal casting and are accumulated in the riser part 3d above the boss part 3a and therefore the product provided with the vanes having the defectless internal quality is thus cast.
