Title: Stall preventive cascade structure
Inventor: KOBAYASHI KENJI
IPC: F01D5/14
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent peeling-off of a boundary layer generated on a root or a leading end of a blade back surface by arranging a blade whose rear end is widened from the center portion to the root portion. SOLUTION: Blades compose a cascade of a turbo compressor. Since flow velocity is decrease as it goes from a front edge to a rear edge at a blade back surface, static pressure is increased at the rear edge compared to the front edge. The blade rear edge is bent and widened toward the root from the center, and similarly bent and widened toward the leading end from the center. The static pressure constant pressure line is also bent. Difference between static pressures applied to the blade back surface generate force. Its reaction F is applied to fluid. The force F is applied thereto perpendicularly to bending at the root side and the leading end side on the rear edge from the center. Component Fy of the force F in the blade root direction or the blade leading end direction is applied so as to suppress peeling-off of a boundary layer.  It is thus possible to suppress the peeling-off of the boundary layer generated on the root or the upper end of the blade back surface.

Title: Brushless dc motor for disk drive
Inventor: JUNG SUNG CHEON
IPC: H02K21/22
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To improve the sealing performance of a liquid dynamic pressure bearing by forming a sealing means on the inner wall of the bearing and shielding the leakage of oil. SOLUTION: A sealing means 19 for preventing oil from being leaked is provided on the upper edge inner-periphery surface of a bearing 11. The sealing means 19 prevents oil from being leaked due to the rise in axial direction caused by centrifugal force and is formed by an enlarged inclination surface that is enlarged and inclined toward the upper part on the upper, inner wall of the bearing 11 and a reduced inclination surface that is reduced and inclined upward. The pressure of oil is reduced rapidly due to the enlarged inclination surface and the reduced inclination surface, thus suppressing the leakage of oil that rises in axial direction. Also, a second sealing means 20 is provided on the upper edge outer wall of the bearing 11.  The second sealing means 20 plays a role of finally shielding oil being leaked from the sealing means 19, thus improving the sealing property of the fluid dynamic pressure bearing.
