The forward/backward rotation controller 15 requires a drive circuit inverting the polarity of a power source for forward/backward rotate- driving a DC(direct current) motor.;COPYRIGHT: (C)1999,JPOAKAMINE FUKAMI
With an electrical motor a thread-spindle is rotated, on which a screw nut is mounted and moving forward or backward depending on the rotation direction. At the endpoints a blockage is avoided by driving the nut-case to a spring-package. A pull-push-pipe in constantly connected with the ...
Grip rotates forward and backward axis structure and rotated forward and backward axis structure of the cameraAn extendable pivot shaft mechanism of a camera for pivoting a rotatable grip on a camera body is provided to allow the rotatable grip both to rotate about a rotational axis and to ...
PROBLEM TO BE SOLVED: To automatically repeat the forward and backward rotation of rotary disks by fixing the rotary disks to both tips of a hollow outer cylinder, fixing one of the rotary disks to a rotary vertical shaft formed for successively passing through the outer cylinder and rotating ...
Clearable counter of watt-hour meter with stepping motor which can rotate forward and backwardThe utility model has an electric meter register which can be reset with a positive inversion stepping motor, which comprises a permanent magnetic type stepping motor, a register stent and a counter part ...
Two driven gears on an output shaft of a driving gear box are rotated reversely with the driving shaft and moved forward/backward along racks to simultaneously move a moving and driving mechanism (1) along guiding rails to a balance position....
