kn-title=On the Phase Adjusting of a Magic T-Coupled Oscillators System
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A magic T-coupled two oscillators system having arbitrary amount of phase adjusting errors is studied both theoretically and experimentally. Denoting two independent phase parameters of the system measured from their optimum values as ƒ¢ƒÓ and ƒ¢ƒÕ, it is derived analytically that the optimum operation is possible in principle in a definite region of ƒ¢ƒÓ - ƒ¢ƒÕ plane, so we have a considerable amount of margin for phase adjusting error. Experimental result also confirms the existence of some phase error margin, though the measured magnitude of margin is smaller to some
extent than the theoretical prediction.

kn-title=Dynamic Behaviour of Attaching Jet
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The dynamic behaviour of attaching jet with single  side wall to step control flow and the switching proces of the bistable amplifiers were investigated experimentally and theoretically. In the experiments, a large scale model was used with water. The flow patterns were visualized by the tracer of polystrene granules and were recorded by a cinecamera. In the analysis, the quasi-steady proces was assumed. The results obtained can be summarized as follows:
1) The proposed analytical dynamic model of attaching jet explains well the dynamic behaviour of attaching jet with single side wall. 2) The process" of the opposite wall switching may be divided into three phases. 3) The analytical model of the opposite wall switching, including the formulation of the switching criterion, was proposed.

kn-title=The Friction Factors of Oscillating Pipe Flows
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=In this study, the friction factors of oscillating pipe flows are experimentally investigated. As the oscillating pipe flow, the pendulation of water column in the special vertical U-tube, which has about the 2 m long horizontal straight foot pipe, is utilized. The results of experiments show that the momentary friction factors in the accelerating state are smaller and in the decelerating state are larger than that in steady state for each Reynolds
