Abstract(in Japanese) (See Japanese page)
Abstract(in English) Statellites employ slip rings to transmit control signals and electric power between the statellite body and the sun-tracking solar paddlies.Slip rings used in space must maintian their lubrivative and conductive characteristics reliably under ultrahigh Vacuum conditions.Friction,wear and electric characteristics of hot-pressed Ag composited were evaluated in a vacuum environment in order to find the optium brush matherial of a slip-ring for space applications. The performance obtaind with the selected Ag-MoS_2-Nbse_2Composite brush and a slivering was superior to that of slip-rings currently used for satellities in low current (1A) and high current (20A) and very high current density(800A, cm^2)conditions.
