Title: Gas turbine control device
Inventor: OZONO JIRO
IPC: F02C9/40
Filed: 1988-11-08
Abstract: PURPOSE:To stably maintain the flame inside a combustor by making a minimum fuel control signal variable by the density of gas fuel, and also by detecting the position of a gas-fuel distributing valve for changing over the minimum fuel control signal. CONSTITUTION:When fuel becomes lean after a load has been cut off, a gas-fuel analyzing device 15 detects the density of gas fuel, and a function generator 16 increases the value of a minimum fuel request signal 8. Consequently, a gas-fuel control valve 9 supplies more gas fuel to a combustor 7, and a stable flame can be obtained in the inside of the combustor 7. When a gas turbine is operated while using both primary and secondary combustion chambers 7-1, 7-2, if the load is cut off, the signal 8 is selected by a high-value priority circuit 6, thereby the control valve 9 is controlled. In this case, a gas-fuel distributing valve 10 is operated, and a bias is added to the signal 8 by a bias generator 17 until such a condition that fuel is supplied only to the primary combustion chamber 7-1 is attained, so that more fuel is supplied through the control valve 9, and the flame inside the combustor 7 can be stably maintained.

Abstract: PURPOSE:To form a dielectric isolated substrate characterized by small warping at a low cost by forming a silicon film which is bonded to a supporting substrate, a silicon oxide film on a silicon nitride film and a plurality of single- crystal semiconductor layers which are isolated from the silicon film with the silicon nitride film and the silicon oxide film and are isolated one another. CONSTITUTION:A silicon oxide film 14 is formed on the entire surface by a thermal oxidation method. A silicon nitride film 15 is further formed on the film 14. Then, a polycrystalline film 16 having the thickness which can fill a V groove 13 is grown. Since the surface of the silicon oxide film 14 is covered with the silicon nitride film 15, silicon pieces formed during the growing step of the polycrystalline silicon film are attached to the silicon nitride film 15. The silicon pieces are not in contact with the silicon oxide film 14. Furthermore, the silicon nitride film 15 does not react with the silicon pieces at temperature lower than the temperature used in the growing step. Since the silicon oxide film 14 is not eroded, the thickness of the silicon oxide film 14 can be made to be about 0.8mum that is one half or less the thickness of a conventional film. The time required for the thermal oxidation step can be shortened.
