This paper investigates micro-parts feeding using a saw-tooth surface. In parts feeding, the driving force applied on each part must vary according to the direction of motion of the part so that the part moves in one direction. Traditional feeders employ oblique or asymmetric vibration of the feeder surface, which often causes unstable motion of… (More)
Synthesis methods of grating lattice filters (GLFs) with poles and zeros are derived. AWG-DMUX cross talk is improved drastically by using GLF with shaper filter characteristics and small size.
