The screw feeder is extensively used as a feeder of granular materials. Until now, a few reports regarding the fundamental characteristics of the screw feeder, for example, the required power and the quantity of discharge from the feeder, have been published. However there are almost no reports on the dynamic characteristics and the transportation mechanism. In this paper, the transporting state and the transportation mechanism of granular materials inside the screw feeder are investigated. First, the effects of the rotating speed of the screw shaft and the pressure of granular materials inside a feed hopper on the required power and quantity of discharge are examined. Secondly, the transporting state of granular materials inside the screw feeder is investigated. Then the transportation mechanism is discussed by analyzing the motion of a tracer inserted into the screw feeder and by using a velocity diagram.

A new control algorithm to achieve trajectory following motion of a motorcycle is proposed in this paper. Presented algorithm is comprised of a feedforward term and a feedback term, the former of which intends to balance forces acting on a motorcycle that have adverse effects for roll motion stabilization, and the latter controls the steering and human lean angle to achieve trajectory following. What is to be emphasized is that the proposed control law is comparably simpler than the ones presented in the foregoing works on motorcycle motion control. Results of both numerical and actual experiments have been described to illustrate the effectiveness of the proposed algorithm.
