Title: High-efficiency driving circuit for active magnetic bearing system
Inventor: RANSU EFU MIRAA
IPC: F16C39/06
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To reduce current drain from the power supply by efficiently using the power supply to a coil by turning on one of coils in turning off the other coil in modulation of a pair of coils arranged in a magnetic bearing. SOLUTION: Current in an electromagnetic coil of magnetic bearings 21, 22, 24 is modulated by a control circuit 70 and the modulation is executed by controlling the duty cycle of the voltage pulse fed to respective coils 30-33, 40-43, 50, 51. The control circuit 70, for example, interleaves on and off intervals for the coils 30, 31 in the electromagnet pairs so that one coil 31 of the pair is being switched off at about the same time as the other coil 30 of the pair is being switched on. As for the polarity of the circulating diodes in the drive circuit 61, the energy being returned from the off-turning coil 31 to the power supply 60 can be utilized for the on-turning coil 30, thereby reducing the net current drain from the power supply 60.

Title: Finned heat exchanger
Inventor: TSUDA YOSHIYUKI
IPC: F28F1/32
Filed: 1985-12-17
Abstract: PURPOSE:To prevent the lowering of the heat exchange ability of the finned heat exchange during the frosting and also prevent clogging between fins due to frosting to prolong the operational time by providing slits each having an inclined limited width in flat fins between heat transfer pipes aligned at a predetermined interval. CONSTITUTION:Into a fin collar portion 7 subjected to burring on flat fins 6, a heat transfer pipe 8 is inserted, and slits 12 are provided between pipes in the stage direction of the heat transfer pipe 8. The inclined side 10 of the flat fins 6 confronts an air current 13 and has a large heat transfer function by an interface layer front edge effect. Further, since air flowing into the in clined side 10 is heat-exchanged once at fin front edge 9, and is removed of its water content to a certain degree, the quantity of frosting is small and clogging is difficult to occur. While the front edge 9 of the flat fin is a portion where it is most liable to produce clogging of fins, the fin surface temperature in a region 115 on the flat fins 6 becomes higher as it draws nearer to a triangu lar tip end portion. Even at the fin front edge portion, a portion where the quantity of frosting is small, and clogging of fins becomes difficult to occur.
