Abstract: The present disclosure relates to a frictional wave reducer mainly used for industrial robot joints and having an operating principle modified from that of a conventional strain wave gearing, which includes a wave generator having a conic pressurizing face on the outermost side, a toothless flex spline having a conic friction tube in which the wave generator is accommodated with the conic pressurizing face inscribed in the conic friction tube, and a toothless circular spline accommodating the toothless flex spline and having an internal conic friction face in which the conic friction tube is inscribed at a plurality of axially symmetrical points to form an internal friction wheel with the toothless flex spline. Accordingly, disadvantages of the conventional strain wave gearing are overcome to provide a reducer having high productivity and high rotation accuracy without generation of vibration and noise.

Abstract: Disclosed is an apparatus and method of monitoring the queue state of a switch in the subscriber board of an asynchronous transfer mode switching system. A difference value between the present time value and a previous input time value stored in a memory per connection is inputted to a forward resource management (FRM) cell when a resource management (RM) cell is inputted from a source, and a switch load measurement value written in the FRM cell is obtained by calculating the difference value between the present time value and a previous output time value stored in the memory per connection when the FRM cell transmitted from the source passes through the switch. The obtained switch load measurement value is inputted to a backward resource management (BRM) cell transmitted from a destination to be transmitted to the switch.

Abstract: A driving cam of a Geneva mechanism includes a core member coupled to the driving cam, and including a circular arcuate portion to correspond to a circular arcuate concave of a driven cam and a groove formed along a peripheral surface of the circular arcuate portion; a plurality of rotating bodies arranged in the groove; top and bottom covers including rims formed at a location corresponding to the groove to be protruded to face each other, the rims having a gap therebetween and preventing the rotating bodies from being removed from the groove when the top bottom covers are coupled to the driving cam and contact upper and lower surface of the core member, respectively; and a coupling means for coupling the core member and the top and bottom covers.
