Title: Standard wafer for measuring lifetime
Inventor: HASHIZUME HIDEHISA
IPC: H01L21/66
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To obtain a calibration standard stable for a long period by subjecting the back surface of an optical pulse irradiation surface to surface recombination accelerating treatment to speed up the surface recombining speed, and setting the lifetime of a carrier to a predetermined value according to the thickness of a semiconductor. SOLUTION: The back surface 6 of an optical pulse irradiation surface 5 is subjected to surface recombination acceleration treatment without the formation of an oxide film to suppress surface recombination, A standard wafer 0 for measuring lifetime is irradiated with optical pulses 1 to generate a carrier C on its surface. As the surface recombining speed of the optical pulse irradiation surface 5 is delayed by the formation of a silicon oxide film 8. the majority of the carrier C is diffused to the inside 9 of the wafer 0. The diffused carrier C is recombined according to bulk lifetime and gradually disappears. When the carrier C reaches the side of the back surface 6, the carrier C is captured in the lattice irregular part 7 of silicon molecules, is immediately recombined, and disappears.  In addition, the thickness of a silicon wafer is changed to set the lifetime of the standard wafer 0 to a predetermined value.

Title: Centrifugal fluid machinery
Inventor: NAGAI YUJI
IPC: F04D29/44
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To improve unstable characteristics caused by reduction of all pump head in a low flow rate region by forming a blade outlet diameter of a spurn water blade smaller than a stage push outer diameter arranged on a sliding part between a stage and a main shaft. SOLUTION: In centrifugal fluid machinery, the entrifugal force by turning at an inlet part of an impeller 3 generates flow from a core plate side in a radial direction, and reverse flow is generated in the vicinity of an inlet side plate of the impeller 3. When the reverse flow is invaded into a return flow passage 7, pre-turning component is enlarged in an equation of a theoretical pump head, and thereby, a unstable characteristic of a pump head characteristic is generated as well as reducing the all pump head. The outlet diameter ϕD of a spurn water blade 6 is formed smaller than an outer diameter ϕD' of a stage bush 8. When it is suppressed that flow in a return flow passage 7 is influenced by reverse flow of a low flow rate region, reduction of the all pump head is eliminated, and the stable characteristic is obtained.
