Title: Slip ring device
Inventor: MATSUU KUNIO
IPC: H02K9/28
Filed: 1990-10-22
Abstract: PURPOSE:To collect brush powder automatically and securely to the filter of an exhaust port by sucking the brush powder to the end of a slip ring cover and springing the powder to the inner periphery of the slip ring cover by centrifugal force. CONSTITUTION:Brushes 2 are always in contact with slip rings 1, therefore, they are worn to produce fine brush powder 7. The brush powder 7 is immediately sucked in the direction of the end of a slip ring cover 3 with a suction fan 5 fixed to the end of a rotor shaft 8. Because the brush powder 7 is heavier than air, it is thrown to the inner periphery of the slip ring cover corresponding to the suction fan 5 by centrifugal force, collected to an ejection path 3a, filtered by a filter 6 at the tip of an ejection port 3b, and removed. Therefore, the brush powder 7 is easily collected and removed by replacing the filter 6.

Filed: 1986-11-27
Abstract: PURPOSE:To enable performing an endurance test for an original cover and a folding part thereof, by mounting respective original cover plates on first and second support members using a universal mounting device. CONSTITUTION:First, an operator mounts one original cover plate 3a on a first support member 5a and the other original cover plate 3b on a second support member 5b using universal mounting devices 4a and 4b.
