Title: Deicing operation method for gas turbine
Inventor: HORII NOBUYUKI
IPC: F02C7/047
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To provide deicing operation method for a gas turbine which does not cause deterioration of performance of the gas turbine even in continuous operation in winter, can sufficiently prevent the inlet of a compressor from icing. SOLUTION: A temperature raising means is arranged for raising temperature of gas to be supplied to a compressor 1. An inlet guide blade 40, which is opened and closed according to load of the gas turbine, is arranged on a gas inlet side of the compressor. The gas introduced into the compressor is increased in its temperature by the temperature raising means compared to the outside temperature, for deicing the inlet of the compressor. In such deicing operation method for the gas turbine, the gas temperature at the inlet is sufficiently increased compared to the outside temperature at the time of starting the gas turbine, by using a means 13 for rising the temperature due to the gas discharged from the compressor 1 and a means 14 for rising the temperature due to ventilation gas of a gas turbine package. After starting the gas turbine, especially after releasing the inlet guide blade, the only the ventilation gas of the gas turbine package is supplied for increasing the gas temperature at the inlet compared to the outside air and operation.

Title: Method for determining analytical equation of fringe scan interference measurement and fringe scan interferometer
Inventor: SHIYU IKUSOU
IPC: G01B9/02
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To make the subject method applicable at the time of the analysis of fringe scan interference measurement exceeding a predetermined number of buckets as well by determining constants in a predetermined equation so as to minimize the error of a phase to be inspected caused by the error of the shift amount of a phase difference at the time of obtaining a phase to be inspected given by a surface to be inspected or an object to be inspected through the use of the predetermined equation. SOLUTION: The same beam is split into measuring light and reference light. The measuring light is reflected at a surface to be inspected, and then both beams are integrated to form interference fringes. The intensity data (g) of the interference fringes at each point at the surface to be inspected is measured, and measurement is which the phase difference between the measuring light and the reference light is shifted by π/2.j (j=0, ±1, ±2,..., ±n; n is a natural number) with respect to a reference state is performed 2n+1 times to measure the intensity data (g) of the interference fringes.  Then at the time of obtaining a phase to be inspected θ given to the surface to be inspected by an equation, if we let the shift amount of the phase difference π/2.j have an error proportional to (j), constants Aj and Bj are determined so as to minimize the error of the phase to be inspected θ caused by the error of the shift amount. By this, application to the analysis of fringe scan interference measurement above 7 buckets is possible.
