Title: Reversible pumpturbine
Inventor: MIYAGAWA KAZUYOSHI
IPC: F03B3/10
Filed: 1995-02-20
Abstract: PURPOSE: To decrease a runner inlet diameter and to reduce friction losses at a runner disk by providing runner vanes each of which has a greater inlet angle on its crown side than that on its band side. CONSTITUTION: In a reversible pumpturbine for use in hydraulic power generation, etc., a runner inlet angle on the side of a crown 6 is made larger than that on the side of a band 7 in such a way that the side of the crown 6 smoothly continues to the side of the band 7. Thus the way of taking contradictory form parameters for the friction loss of a runner disk existing in the reversible pumpturbine and for pressure losses due to collision at a runner inlet 8 caused by cavitation at the runner inlet 8 is avoided to improve cavitation performance at the runner inlet 8. Because of the decrease in the pressure losses due to collision at the runner inlet 8, etc., the reversible pumpturbine has enhanced efficiency and can be operated up to low-output openings.

Title: Semiconductor device
Inventor: NAKAJIMA HIROOMI
IPC: H01L21/28
Filed: 1990-02-14
Abstract: PURPOSE:To prevent the breakdown of a shallow junction formed by polysilicon emitter, by arranging a high melting point metal film between a second polycrystalline silicon film and a metal film for wiring, and filling a step- difference part of the second polycrystalline silicon film with the high melting point metal film. CONSTITUTION:Since a tungsten film 32 on a polycrystalline silicon film 31 is formed by CVD method, a step-difference part at an aperture part 25 of the polycrystalline silicon film 31 is filled with the tungsten film 32, and the base of an aluminum film 33 is flattened. As a result, on the emitter forming egion, the contact surface between electrode wiring material like the aluminum film 33 and an interlayer insulating film formed on the film 33 is flattened too. Thereby the stress caused by thickly stucking an interlayer insulating film on the step-difference structure of the trench of the electrode wiring material in the conventional way is reduced. Further mutual diffusion of emitter polysilicon and aluminum is restrained by the barrier effect of tungsten. Hence a shallow junction formed by a polysilicon emitter is not broken down.
