Title: Steam turbine controller
Inventor: TSUJI HIROSHI
IPC: F01D17/20
Filed: 1991-01-10
Abstract: PURPOSE:To prevent fluctuation of steam pressure at the inlet of a turbine by providing a rate of change limiter, which gradually changes an opening command signal for a steam control valve in such a way that a closing speed of a turbine bypass valve does not exceed the maximum opening speed of the steam control valve. CONSTITUTION:In a nuclear power plant, the steam generated in a nuclear reactor goes through a main steam stop valve and a steam control valve (CV)3 and flows into a turbine. A part of the steam, however, goes toward a turbine bypass valve (TBV)6 from this side of the main steam stop valve in order to be discharged into a condenser. In the abovementioned constitution, a CV initial opening command value outputted from a low value selecting device 14 is inputted into a rate of change restricting device (23) and is then taken out as a CV opening command value. After this, based on CV opening command value, a deviation between respective actual opening signals of the CV3 or TBV6 is obtained by adders 16, 20. Moreover, the valve opening of the CV3 or TBV6 is controlled via valve driving devices 17, 21.

Title: Manufacture of semiconductor device
Inventor: IMAI KEITAROU
IPC: H01L21/316
Filed: 1986-01-10
Abstract: PURPOSE:To improve insulating characteristics, by performing thermal oxidation under the state a CVD oxide film is present, and forming a thermal oxide film having a uniform thickness on the surface of a silicon layer having irregularities. CONSTITUTION:An insulating film 2 is formed on a silicon substrate 1. A CVD oxide film 3 is deposited, and a groove 4 is formed. Thereafter, an oxide film 3 is removed, and an oxide film 5 by a CVD method is deposited. Thermal oxidation is performed, and a thermal oxide film 6 is formed on the surface of the silicon substrate 1 beneath the CVD oxide film 5. At a corner A at the recessed part, oxidation speed is decreased owing to the concentration of stress at the thermal oxidation. As a result, the interface between the formed thermal oxide film 6 and the silicon substrate 1 becomes round. At a corner B at the protruded part, stress concentration is similarly formed. At this part, the amount of oxygen, which is diffused in the CVD oxide film 5 and supplied to the silicon substrate 1, is more than that in the flat part. Therefore, the effect of the decrease in oxidation speed can be compensated. Thus, the thermal oxide film 6 becomes thick, and the round part is effectively formed. Therefore, the thickness of the corner part of a thermal oxide film 7 as a capacitor insulating film, which is finally formed, does not become thin.
