Title: Alignment device
Inventor: MURAKAMI SHIGEO
IPC: H01L21/027
Filed: 1987-02-25
Abstract: PURPOSE:To make highly accurate alignment by scanning spots produced by irradiation light for alignment or special patterns to obtain relative positional information between a mask and an exposure substrate. CONSTITUTION:When the angle of a vibration mirror 26 changes continuously, incidence direction of an irradiation light LB to a reticule mark changes continu ously. When positions of spots SU and SD change, positions of spot images formed at the position in cooperation with these change. Spot positions on slits 44, 50, 56, and 58 are measured by a grating 42. When a spot pattern PG caused by incidence light moves in the direction of an arrow F1 as a vibration mirror 26 vibrates, the intensity of penetrated light changes in the form of a sine wave or triangle wave. This change is detected by a detector 46. Processing, for example, signals of frequency division, etc., obtains position pulses. By counting this, spot positions can be measured.

Abstract: PURPOSE:To automatically correct the floating of a valve position signal due to the thermal expansion of a valve element so that stable and precise operation is ensured, by providing a valve position floating compensation circuit comprising a steam flow detector and a memory circuit, in a steam turbine control device. CONSTITUTION:In a device for controlling a steam turbine, there are provided a steam valve position detector 61 and as well a valve position floating compensation circuit comprising a steam flow detector 62 and a memory circuit 64. A signal L from the valve position detector 61 is stored in the memory circuit 64 to follow the operation of the valve position detector 61 so that a signal operator 65 normally delivers its output L-B=0. Upon starting of the turbine, when a valve rod reaches the position where steam initiates to flow so that the steam flow detector 62 is actuated, a switch 63 opens to block the signal input of the memory circuit 64 which therefore memorizes the signal L at this time. Accordingly, when the steam valve is opened, the output of the operator 65 is detected as a displacement from the starting position of valve opening where control is required.
