Abstract

PURPOSE: To detect horizontal and vertical acceleration, by sealing a magnetic fluid into a large-dia. part at the center of a closed pipeline to arrange photoelectric detectors for surface light emitting and receiving elements at specified points of a small-dia. part extending horizontally and vertically from the large- dia. part.
CONSTITUTION: A magnetic fluid 3 is sealed into a large-dia. part 1a at the center of a closed pipeline 1 made of a nonmagnetic material and magnetic couples 4a, 4b, 5a, 5b, 6a, 6b, 7a and 7b are arranged at specified points of tubules 1bW1e being extending from the large-dia. part 1a. Surface light emitting elements 8aW11a are arranged at the specified points of the tubules 1bW1e and face surface light receiving elements 8bW11b through the tubules 1bW1e to form photoelectric detectors with these elements. When an action force by acceleration overcomes a coercive force with the magnetic couples, the magnetic fluid 3 is displaced opposite to the direction of acceleration and a part thereof flows out to the tubule 1d. Thus, a differential output is generated in right and left photoelectric detectors according to acceleration.
