摘要： A first controller (39) includes a phase shifter (42), a high-gain amplifier (43) and a saturating element (44). A first vibratory exciter (41) generates a first vibrational force in the horizontal direction. A first vibrational system (32) of an elliptical vibratory machine receives the first vibrational force, and first vibrational displacement detecting means (33) detects the vibrational displacement of a movable part of the elliptical vibratory machine in the horizontal direction. A second controller (34) includes a phase shifter (45), a high-gain amplifier (46) and a saturating element (47). A second vibratory exciter (36) generates a second vibrational force in the vertical direction. A second vibrational system (37) of the elliptical vibratory machine receives the second vibrational force, and second vibrational displacement detecting means (38) detects the vibrational displacement of the movable part in the vertical direction. A closed loop is formed by the above parts, the output of the second vibrational displacement detecting means (38) being negatively fed-back to the first controller (39). The shift angles of the first and second phase shifters (42,45) are set so that there is a phase difference of 180 DEG between the output of the second vibrational displacement detecting means (38) and the input of the first controller (39) when electrical connection therebetween is broken, and a predetermined phase difference can be obtained between the vibrational displacements of the first and second vibratory systems (32,37) for the optimum condition of the elliptical vibratory machine, the first vibratory system (32) being self-excitedly vibrated at its resonant frequency and the second vibratory system (37) being self-excitedly vibrated.

摘要： In a vibratory apparatus (21) including vibratory speed detecting means (32) for detecting a vibratory speed of a vibratory machine (31), a self-excited oscillation controller (35) is provided for amplifying the output of the vibratory speed detecting means (32) at a feed-back gain K, receiving the output of the vibratory speed detecting means (32) as a positive feed-back signal. A power amplifier (36) amplifies the output of the self-excited oscillation controller (35) and a vibratory exciter (37) receives the output of the power amplifier (36) for vibrating the vibratory machine (31). The feed-back gain K is changed in accordance with the equation: where DELTA r represents the amplitude difference between a predetermined amplitude and the present amplitude, K1, K3 are constants, and Kcr is the critical stability gain.

摘要： The conveyor has a delivery drum with spiral path, vertical and horizontal stimulation units with electromagnetic coils (12,15a,15b) and spring units supporting the drum and allowing vertical and horizontal vibration. A phase difference in the coil currents produces an elliptical vibration varied in axial ratio or inclination by varying (100) the phase of one coil current.
