Abstract: PURPOSE: To quickly open a turbine by-pass valve to prevent the rise in the steam pressure of a nuclear reactor, by providing a reservoir vessel and a quickly opening solenoid valve for a servo-operating cylinder for operating the turbine by-pass valve.  
     CONSTITUTION: The turbine by-pass valve 4 of a nuclear power plant is quickly opened at the time of disconnection of load from a turbine 2 to by-pass the excess steam of a nuclear reactor 1 to a steam condenser 3. At that time, oil in the valve closing side oil chamber 5b of a servo-operating cylinder 5 is drained to a tank 14 through a quickly opening solenoid valve 7 and also temporarily drained to a reservoir vessel 17 of large capacity. As a result, the pressure of the valve closing side oil chamber 5b falls sharply so that the turbine by-pass valve 4 is opened quickly. Thus, the excess steam can be by-pased to the steam condenser 3 in a short time to revent the rise in the steam pressure of the nuclear reactor 1.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor production system in which highly accurate alignment can be conducted while enhancing throughput. SOLUTION: In a semiconductor production system where a pattern on an original mask plate is projection aligned to wafer 5 mounted on an XY movable stage, an alignment mark on the wafer 5 is measured by means of a storage type alignment sensor 12. The stage is subjected to simultaneous control of movement in the measuring direction and nonmeasuring direction of the alignment mark. When the alignment mark moves under the sensor 12 and the stage is stationary in the measuring direction, storage of the sensor 12 is started if the mark is present within a predetermined range even during movement of the stage in the nonmeasuring direction and the position of stored alignment mark is calculated.  Furthermore, the order for measuring a plurality of alignment marks on the wafer 5 is selected to increase such movements as the moving time of the stage in the measuring direction is shorter than the moving time in the nonmeasuring direction.
