    摘要: A piezoelectric driven type vibratory feeder having a working mass member that vibrates stably over an entire area of the working mass member is disclosed. The piezoelectric driven type vibratory feeder includes a base, a plurality of first plate springs, with a lower end portion of each of the plurality of first plate springs being secured to the base. A working mass member connected to an upper end portion of each of the plurality of first plate springs and supported at the base to enable the working mass member to vibrate. The piezoelectric feeder also includes a plurality of second plate springs, a piezoelectric device bonded to at least one surface of each of the plurality of second plate springs. An alternating voltage is applied to each piezoelectric device whereby each second plate spring undergoes bending vibration and causes the working mass member to vibrate so that an object is transported on the working mass member.

    摘要: In a pyrometallurgical smelting method of copper, the copper-ore and auxiliary fuel, such as carbonaceous material, is blown through an ore-concentrate burner into a reaction shaft. In an improved pyrometallurgical smelting of copper, the carbonaceous material is used to reduce the Fe.sub.3 O.sub.4 contained in the slag. The present invention provides an improved method for reducing the Fe.sub.3 O.sub.4 even in a case at a decreased amount of auxiliary fuel is to be decreased. The carbonaceous material is blown into a lower portion of the reaction shaft where the oxygen partial pressure is low.
