SOLUTION: In the impeller 1 for a centrifugal compressor, each short blade 4 is erected between two long blades on a hub surface 2 of the impeller 1 in the circumferential direction at an uniform pitch alternately. In the short blade 4, the length of gas flow direction is shortened by the long blade 3. The leading edge 4a of the short blade 4 is positioned in the gas flow direction from the leading edge 3a of the long impeller 3 and downstream of the impeller 1 axial direction. The trailing edge 4b of the short blade 4 is made to coincide with the trailing edge 3b of the long blade 3 on a position of the gas flow direction and the impeller axial direction. A throat area is nearly equalized, and gas flow rates are equalized between the pressure surface side and the negative pressure surface side of the short blade 4.

Title: Abrasive material
Inventor: KURASAWA MORIO
IPC: B24B37/00
Filed: 1987-01-29
Abstract: PURPOSE:To improve both abrasive strength and accuracy of finished surface regarding an abrasive material for grinding crystal and the like by constituting with silicon carbide mixed with niobium-related substance containing 0.5-20% weight of niobium. CONSTITUTION:Since an abrasive material for grinding, dicing, and honing crystal, ferrite or the like for example is constituted by mixing niobium-related substance containing 0.5-20% weight ratio of niobium, an effect not to coagulate silicon carbide during grinding and an effect to melt ground object are obtained due to the niobium-related substance mixed uniformly in the silicon carbide. Therefore, the abrasive material effects always fresh abrasive effect on the ground object, causing a great abrasive strength even with a small diameter of the abrasive material particles. Since the abrasive material does not coagulate during grinding, the ground surface is not damaged and moreover it is possible to obtain a fine finish of the surface due to the effect of melting the surface. Thus, rationalization becomes possible by performing from rough grinding to finishing in one process.
