摘要： PROBLEM TO BE SOLVED: To correct one-sided run of a belt for a belt feeder automatically by displacing one bearing of a driven pulley in the longitudinal direction based on a detection signal from the one-sided run detector of a feeder belt. SOLUTION: If a belt 7 is one-sided to the right, this is detected by an one- sided run detector 14a on the right side, and its detection signal is transmitted to a controller 15. The controller 15 displaces a left bearing 9b by a fixed distance rearwards to control driving a special motor 13. The left bearing 9b displaced by the fixed distance rearwards, and the shaft of a tail pulley 6 inclines by a fixed angle rearwards with a right bearing 9a serving as a fulcrum to correct the one-sided run of the belt 7. If the belt 7 is one-sided to the left, this is detected by a left one-sided run detector 14b to correct the one-sided run of the belt 7 in the same way as for rightward-sided run. In the above way, automatic correction can conducted. It is thus possible to eliminate manual one-sided run correction work for a belt feeder.

摘要： PURPOSE:To prevent the clogging and wearing damage of a chute by a method wherein the chute is formed by forming a plurality of wire ropes arranged in parallel with a pallet in the widthwise direction at a predetermined interval from the upper end to the lower and so as to obtain the shape of a screen through a plurality of guide liners. CONSTITUTION:A chute 8 is formed of a plurality of wire ropes 10, arranged in parallel with a pallet in the widthwise direction at a predetermined interval from the upper end toward the lower end, and a plurality of guide liners 12, having a bush 13 at a penetrating part supporting the wire rope 10, so as to have the shape of a screen. The wire rope 10 is coated with urethane resin. On the other hand, the bush 13 of the guide liner 12 is formed of urethane resin. According to this method, the wire rope 10 is vibrated by the material dropped on the chute 8 while the adhesion and accumulation of the material are precluded by the vibration, whereby the wearing damage to the chute can be prevented.

摘要： PURPOSE:To produce a magnetic metal powder having uniform grain diameter and composition by introducing the halides of the metals such as Fe, Co and Ni into a high-temp. evaporator, vaporizing the powder with the heat of a preheated inert gas and reducing the powder in the vapor phase. CONSTITUTION:The powder of the raw material such as FeCl2 19a and CoCl2 19b having =700 deg.C and heated by a heater 16 and the heat of a preheated dilution inert gas introduced therein. Consequently, the powder is rapidly vaporized, and the raw material vapor of stabilized partial pressure is obtained without substantially forming the liq. surface of the molten halide in the evaporator 13. Thereafter, the vapor is then introduced into a reaction furnace 11 and reduced in the vapor phase by the H2 supplied from an inlet pipe 21 at the reaction part 23 kept at >=about 900 deg.C. The magnetic metal powder of Fe-Co, etc., thus formed is recovered by a powder separator 29.
