The stress in the rotating disc, that is widely in practical use especially in the steam turbine disc wheel, had hitherto been calculated for a few particular sections. Prof.T.Suhara derived the solution of the displacement equation for any thin rotating disc of various sections, in the form of hypergeometric series. The writer accomplished the numerical calculation of stress for such discs, and investigated the relation between the stress and the form of the section. For a practical example the result of the stress calculation for the film drum of Prof.Suhara's super high-speed kinetocamera is shown.

The present report describes the two problems on two dimensional (1) Flow past a sort of an inlet valve, with a 1ittle consideration on the effect of fillet between the valve head and stem to flow quantity as an application of the solution. (2) The calculation of the velocity at a point on an elliptic cylinder in wide stream.

The present paper is an attempt to investigate the various hydraulic phenomena occuring in pipe lines due to the operation of valves, ruptures etc. and to draw attention to the risks attendant upon using the various so called approximate equations, which have from time to time been proposed, for calculating the pressure variations. Attention is also directed to the necessity for recognising the fundamental differences between the short pipe lines of hydro-electric plants and the long pipe lines of water supply and irrigation systems when investigating the surge phenomena supervening on an alteration of regimen. Finally a description of the various types of valves is given together with a discussion of some important points of design and the trend of recent improvements in design.
