IPC: F04D21/00
Filed: 2003-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To reduce pressure loss by controlling a shock wave generated at a leading edge of a high turn/high transonic aerofoil used for a blade cascade for an axial compressor.  <P>SOLUTION: A flow rate distribution at a backside of the leading edge of the high turn/high transonic aerofoil used for the blade cascade for the axial compressor has supersonic portions k to l which are located at a rear side of a first local maximum value j of the flow rate are approximately constant in flow rate and within a 15% position of a chord length. In the supersonic portions k to l, a value dividing a Mach number difference ΔM between the back and forth ends by a chord length direction ΔX/C is less than 1, and the maximum Mach number of the transonic portions k to l is less than 1.4. A great first shock wave is positively generated at the position where the flow rate becomes the first local maximum value j to weaken the second shock wave generated at the transonic portions k to l whose rear flow rate is approximately constant so that pressure loss in a rear flow of the blade can be greatly reduced by suppressing a boundary-layer separation owing to the second shock wave.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Quartz crucible for pulling silicon single crystal
Inventor: WATABE HIROYUKI
IPC: C03B20/00
Filed: 2003-03-26
Abstract: <P>PROBLEM TO BE SOLVED: To enhance the yield of a silicon single crystal and improve the quality of the silicon single crystal in pulling it by melting the corner R portion at a temperature higher than that of the upper part in a method for producing a quartz crucible in contact with a silicon melt.  <P>SOLUTION: In producing the quartz crucible, a silicon melt in contact with the corner R portion of the quartz crucible is melted at a temperature higher than that of a silicon melt in contact with the upper portion; thus, a crucible in which the quartz glass structure of the quartz crucible upper portion in contact with the silicon melt contains an amorphous component in a content lower than that of the corner R portion is yielded. The crystallization rate of the corner R portion exposed to high temperature for a long time becomes low, enhancing the yield in single crystallization. By lowering the melting temperature of the crucible upper portion, the occurrence of liquid-level vibration is prevented and the oxygen concentration in the silicon single crystal is caused to be uniform.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
