Description of the invention (4) Intermediate connection gate fluid, the gate electrode of the gate fluid is supplied by the pulse electrode generation circuit of the gate electrode For the current control system, the current phase of the line-driven magnetic pulse electrode moving gate drive is pre-phased into the constant current. The pre-fabricated control device and the point source of the pressure arc are used to place the electric current flow of the point source. The power distribution system in the middle of the road is controlled by the power supply system. The father drives the front device and the pulse of the vibrating electromagnetic power generation. From the line, the magnetic power supply drives the drive circuit to drive the pre-produced surge pulse arch gate, presses the pre-electrode dynamic direction, changes the output source current, and directs the pre-control system to control the drive from the device. Vibration of the magnetic voltage In the above formula becomes the forward pulse with the corresponding bit of the amount of the red side of Formula extremely. The dynamic road is used as a straight path to transport the current. The current is adjusted to the amount of current. 33 The source current of the transformer is to be exchanged (please read the precautions on the back before filling in this page). The flow pulse square is changed in the S phase change phase to compensate for the stamping pulse compensation pulse. The gate change is adjusted by the pole movement, and the pressure is adjusted to the pressure generating pulse current pulse generated by the small arc electric point at the corner. The change of the gate pole makes Lan Yuyi correspond to the right, and the quantity is determined one by one in order to maintain a large linear amplitude of the vibration of the coil. The magnetic actuator can be driven into the magnet. The galvanized electricity is made with cocoa.

In the figure, the commercial AC power supply 1 is connected to the transformer 2 to implement step-down, for example, the step-down voltage is 16V and is supplied to the rectifier circuit 3. The rectifier circuit 3 acts as a full-wave rectifier circuit when the switch 10 is closed via the diodes 4, 5, 6, 7 and the diodes 8, 9 act as a half-wave rectifier circuit when the switch 10 is opened. Way composition. The electric circuits 11a, 11b are derived from the rectifier circuit 3. This part is also connected to the pulse signal generating section 12 of the present invention. At this time, a voltage that is smoothed by the smoothing capacitor 13 inserted between the electrical line 11a and the ground terminal is supplied from the electrical line 11a and is proportional to the voltage of the commercial AC power source 1. Furthermore, a rectified voltage that is rectified into a full wave or a half wave and has a ripple is supplied from the electric line lib. 14 is for stabilizing the power supply circuit, and the input from the electric circuit 11a is obtained. The voltage of the commercial AC power supply 1 is irrelevant, so that a level DC voltage 12V is supplied to the pulse control signal generating section 15. The pulse width control signal generating unit 15 is known, and is composed of a soft start setting unit 17, an upper limit adjustment setting unit 18, a lower limit adjustment setting unit 19, and a notch wave (notch) setting unit 20 Timing generates the pulse width, which is the signal that controls the arc angle of the point. The slow start (s ftstart) setting unit 17 is a circuit that controls the pulse mode by whether the vibration system reaches the normal state or stops when the start signal or the stop signal is applied through the electric circuit 16, and furthermore, the upper limit adjustment setting unit 18 and the lower limit adjustment The setting section 19 is a circuit for adjusting the upper limit and lower limit of the amplitude, and the notch wave setting section 20 is a circuit for setting a predetermined amplitude. The pulse signal generating unit 12 is, as shown in Fig. 1 (b) showing the detailed status, including an arithmetic unit 1 2 a, a waveform shaping circuit 1 2 b and a comparator 1 2 c, forming the wiring shown in the figure. In addition, 2 1 is a RUN lamp, and it also means that the drive control circuit is currently the original paper standard. The Chinese standard (CNS) A 4 specification (210x297 male) is used.

Description of the invention (7) (Please read the precautions on the back before filling in this page) The calculation control is used as the output signal of the calculator 12a to obtain a positioning criterion shown in Figure 4. The signal V b. Then, the output signal V b of the calculator 1 2 a and the output signal (sawtooth wave) V a of the waveform shaper 1 2 b are input to the comparator 1 2 c, and the output signal of the comparator 1 2 c is obtained as 4 shows the gate signal row and column ga. As a result, the portion indicated by the diagonal line in the voltage of the commercial AC power supply 1 (represented by Vx in FIG. 4) becomes the point arc angle. That is, for the gate 4 1 a of the triac (TRIAC) 4 1 in FIG. 3, the gate pulse row ga of FIG. 4 is supplied, so that the bidirectional triode 41 at the portion indicated by the oblique line of the voltage Vx In the arc, the corresponding current flows into the coil 35 of the vibrating parts supplier 30. As a result, the torsional vibration force determined by the notch wave setting unit 20 is obtained, and the bowl 31 performs torsional vibration. However, it is assumed that the voltage of the commercial AC power source 1 changes. For example, the output signal Vb of the calculator 12a in Fig. 1 (b) decreases as indicated by the broken line in Fig. 4 as the voltage Vx of the commercial AC power supply 1 decreases. At this time, the comparator in the pulse generating unit 12 is printed by the Peking Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. The gate pulse train ga supplied by 1 2 c is increased by the pulse as shown by the virtual cotton, thereby making the commercial AC power supply 1 The falling voltage VX accelerates the point of arc time. Due to this, the arc angle of the bidirectional triode (TRIAC) 41 increases, so that the coil current acts in a direction corresponding to the increase of the voltage drop to become a predetermined current, thereby transferring the predetermined torsional vibration force to the bowl (B 〇wi) 3 1 supply. As a result, the bowl 31 vibrates with a predetermined amplitude. Next, the case of closing the switch 10 of the rectifier circuit 3 will be described. In this case, the voltage of the commercial AC power supply 1 is half-wave rectified, and the wave number of the sawtooth wave Va in FIG. 4 is halved, thereby doubling the generation period of the wrist-rushing row ga, but the operation is the same as the foregoing The situation when full wave rectification. In addition, for half-wave rectification of the circulating current circuit of the coil in Figure 3, the paper size is in accordance with the Chinese National Standard (CNS) A 4 specifications (210x297 mm) Λ 6 η 6 Annex IV Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs Printed 5. Description of invention (g) The bidirectional triode (TRJAC) described above can be replaced by a unidirectional thyristor 41. The above is the case when the voltage of the commercial AC power supply 1 drops. When the voltage rises, then The generation time of each pulse of the gate pulse train ga is accelerated to perform constant voltage control. The embodiments of the present invention have been described above, but the present invention is not limited to the foregoing embodiments, and various modifications can be made according to the technical idea of the present invention. For example, in the above embodiment, the vibration parts feeder 30 in the electromagnetic vibration machine is described, but for a general electromagnetic vibration machine, such as an electromagnetic vibration feeder (feeder *) or a vibration screw elevator (spival elevator), the present invention Also applicable. In addition, in the previous embodiment, the rectifier circuit functions as a half-wave rectifier circuit and a full-wave rectifier circuit, but K may be changed to any one of them. [Effects of the invention] As described above, the drive control circuit of the electromagnetic vibrator of the present invention is such that the vibration of the movable part of the electromagnetic vibrator can be approximately a certain value even if the power supply voltage changes, and it can be not used.
