Abstract

PURPOSE:To avoid the deterioration of the control function and performance to ensure the operation for a long period for a feeder device, by supplying the control current to an electric device provided to a rotary antenna, etc. of a radar from an electric device fixed on the ground and via an opposite electrode which has no mechanical contact sliding action. CONSTITUTION:An electrode 13 is formed with use of a conductive material onto a circular disk having a round hole at the center, and an electrode 14 to be bonded to a fixed matter 1 such as a radar basement, etc. is formed into a disk shape with use of a conductive material so that the center axis of the circular hole coincides with the center of the rotary shaft of a mobile matter 2 like a rotary antenna, etc. The electrodes 13 and 14 are set opposite to each other with a prescribed distance secured between them, and the air circulates from outside into the gap between these electrodes. Thus an accumulator using the air as a dielectric material 15 is formed with no contact to the matter 2 and regardless of the rotation or nonrotation of the matter 2. The signal voltage of an electric device attached to the matter 1 charges and discharges the electrodes 13 and 14 via a current closed path 16 and then supplied to an electric device 4 to be attached to the matter 2 in the form of an analogous driving current.
