Title: Gas turbine control device
Inventor: MIZUNO TAKASHI
IPC: F02C9/28
Filed: 1995-02-17
Abstract: PURPOSE: To perform operation of gas turbine with gas turbine efficiency increased to a high value while the thermal stress of a gas turbine is prevented from generation even when the fluctuation of a system frequency is produced by a method wherein an exhaust gas temperature control signal or a load limit control signal is selected as a fuel control signal. CONSTITUTION: During ordinary running, an exhaust gas temperature control signal FT or a load limit control signal FLL produces a fuel control signal FREF. Since a speed load control signal FN follows in a position higher by a margin value FBA than an exhaust gas temperature control signal FT or a load limit control signal FLL, the speed load control signal FN is lowered from a position higher by the margin value FBA and even when it is selected as the fuel control signal, rapid disturbance does not occur. Further, when a fuel flow rate is adjusted by means of the exhaust gas temperature control signal FT, even when the exhaust gas temperature control signal FT is rapidly increased, the speed load control signal FN follows only at a maximum follow rate determined by the upper limit set value of an upper limiter 46, the rapid change of a fuel flow rate is suppressed.

Title: Copying machine
Inventor: MIYAGI TAKESHI
IPC: G03G15/04
Filed: 1983-03-30
Abstract: PURPOSE:To improve the accuracy of detection of a moving position by measuring an arrival time from a stop position detecting sensor HP to an image tip detecting sensor OHP in moving an original image to the rear part of a copying paper sheet by moving a part of an original in the subscanning direction. CONSTITUTION:A noticed part PX of an original GK is moved to a desired position on a copy paper sheet P. X direction is taken as the subscanning direction and the Y direction is taken as the main scanning direction. A reference point of the original GK exists in the left end and corresponds to the position of the image tip detecting sensor OHP of a reader section. In figure, tp is a time width corresponding to an image position moving distance and t1 is a time while a scanning unit moves between the sensors HP and OHP. The time t1, however, is not constant because of the change in the speed of the scanning unit and the variation in the stop position. In order to measure accurately the time t1, the time t1 is measured by scanning the original with the same condition as that at copying. Thus, an offset is produced between the scanning start time of the scanning unit of the reader section and the transfer paper resist drive time of the printer section is produced by the time of tp+t1=tx at the movement of the part PX, allowing to attain the accurate original movement.
