Title:
MAGNETIC POWDER CARRYING DEVICE
Document Type and Number:
Japanese Patent JPH0415673
Kind Code:
A
Abstract:

PURPOSE: To carry magnetic powder without using a rotating mechanism by laying plural conductors in parallel along a specified path in the width direction of the path, coating the conductors with a jacket member consisting of a non-magnetic material and conducting alternating currents whose phases are shifted by proper amount to the juxtaposed conductors in arranging order.

CONSTITUTION: The conductor parts 4 are divided into proper number of sets where there are the same even-number of conductor parts, and the respective sets of conductor parts 4 are equally dispersed and arranged around a supporting body 3. Namely, in the case that the conductor parts are divided into (m) sets, the respective sets of conductor parts 4 are arranged in alternate (m-1) lines. As to the traveling direction of the conductor part 4 of each set, the traveling direction of the conductor L is reverse between to odd-numbered set of conductor parts 4 and the even-numbered set of conductor parts 4, so that the conductor parts 4A and 4B which belong to different sets are arranged to travel in the same direction in a state where they are arranged in two lines. By conducting the alternating currents of (m) kinds [(m) phases] whose phases are shifted by π/m to the (m) sets of the conductor parts 4 in arranging order, progressive wave magnetic field which progresses in the direction of C is formed. Thus, the magnetic powder is carried without providing the mechanical rotating mecha nism.
