Abstract: PURPOSE:To substantially make uniform the quantity of absorption of radioactive rays of the photosensitive material in the region of exposure by a method wherein the speed of shifting of the front and the rear edges of a shutter device for the passage and interruption of radiant rays passing the region to be exposed is controlled. CONSTITUTION:A sensor 104 is provided on a wafer shifting stage 103, the sensor 104 is shifted in X and Y directions, and it measures the intensity of illumination of an optional point in an irradiation region 120.

Title: Governor inlet pressure control device
Inventor: KISHIKAWA TADAHIRO
IPC: F01K23/10
Filed: 1990-09-13
Abstract: PURPOSE:To prevent cavitation of a waste heat boiler forced circulation pump by raising pressure setting once when controlling pressure of an S/T governor valve inlet, and then lowering the setting pressure to prescribed pressure by a chance rate of prescribed pressure. CONSTITUTION:Systems of two G/Ts, two waste heat boilers, and an S/T are described. A waste heat boiler on the side where one G/T tripped loses the heat source, and also loses the steam generating performance suddenly, so that S/T governor front pressure also drops suddenly. Therefore, steam from the surviving waste heat boiler increases suddenly, and pressure at the surviving waste heat boiler also drops. To prevent sudden drop of the pressure at the surviving waste heat boiler, the front pressure of an S/T governor is controlled and set. By pressure setting, the S/T governor valve is closed suddenly, so that it prevents governor front pressure from dropping and makes subsequent pressure drop to prescribed pressure smooth. It is thus possible to prevent the pressure of the forced circulation pump of the waste heat boiler from dropping suddenly.

Title: Phase locked oscillation circuit
Inventor: ITO HIROSHI
IPC: H03L7/107
Filed: 1986-10-14
Abstract: PURPOSE:To reduce a time necessary for a phase locking by selecting a filter circuit whose time constant is small when the delaying or leading phase of an output clock against an input clock is large. CONSTITUTION:A phase comparison detection circuit 1 detects the delaying or leading phase quantity (p) of the output clock f2 against the input clock f1 so as to compare with the phase quantity pm of a set threshold and when the quantity (p) is larger than pm it outputs a control signal to a selection circuit 6. Thus the circuit 6 selects the filter circuit 5 which is set in small time constant tau1. Therefore the time necessary for the phase synchronism can be reduced. Next, if a phase adjustment proceeds so that the quantity (p) becomes less than pm, the circuit 1 outputs the signal telling the effect to the circuit 6, which selects the filter circuit 3 which is set in a long time constant tau2. Namely, in the steady state where a phase difference between the clock f1 and f2 is a little, the circuit 3 is selected to prevent a jitter, etc., so that a stable action can be secured.
