Filed: 1987-03-24
Abstract: PURPOSE:To protect a beryllium window and to stabilize an exposure, by controlling operation of a switching means such as a shutter or the like in accordance with information on gaseous concentration as detected. CONSTITUTION:An X-ray 10 from a target 2 is applied into a hellium chamber 7 through a window 6 provided by a thin film of beryllium or the like. A mechanical shutter 5 is arranged between the window 6 and an X-ray source such that it is opened by a drive section 20. A concentration of oxygen in the chamber 7 is detected by a concentration sensor 8. A control circuit 24 receives information on the oxygen concentration detected by the sensor 3 and determines whether exposure can be performed without breaking the window 6 at such oxygen concentration. If determined impossible, the control circuit inhibits the drive section 20 from opening the shutter even if the operator gives it a command to start exposure. If exposure is possible at the detected oxygen concentration without damaging the window, the control circuit corrects a duration of time for opening the shutter 5 in accordance with that concentration, and outputs a command to the drive section 20 so that a constant and appropriate exposure is given to a wafer 11.

IPC: G01D5/48
Filed: 1988-03-24
Abstract: PURPOSE:To measure even the absolute position of the one-axial moving position of the moving body with resolution of submicron or high accuracy as well as the relative position by generating a surface acoustic wave on a surface acoustic wave propagation path without contacting and using it as a ruler. CONSTITUTION:The moving body 1 moves integrally with a body to be measured and the surface acoustic wave propagation path 2 is formed on its surface. Then a high-output semiconductor laser 4 performs pulse oscillation at a repetitive period of certain frequency in the band of an inter-digital electrode (surface wave transducer) 3. Its output is amplified by a semiconductor laser driving circuit 11 to a proper level so as to obtain a desired output. Then laser light after pulse-intensity modulation is projected on the propagation path 2 to generate the surface acoustic wave by optoacoustic effect at the irradiation point as a wave source position, and the wave is detected by the electrode 3. Then the wave is amplified 12, and a phase difference detecting circuit 13 detects the phase difference from the reference signal from a reference signal generating circuit 9. Those measurement data are processed by a central arithmetic unit 15 to calculate and display the angle of rotation on a display device 16 finally.

IPC: B60R1/06
Filed: 1990-03-20
Abstract: PURPOSE:To simply dissolve a state of collision between a door mirror and an obstacle even when the door mirror collides against the obstacle in rotating to its return position by providing a signal generating circuit for generating a cancel sigal which forcedly keeps a return action switching element in an off-state for a short time during early output of a rotation command signal. CONSTITUTION:In a case where door mirrors are struck against an obstacle by rotating the door mirrors 4, 5 from a housing position to a return position in a narrow place such as a garage, an operation switch 12 is operated to issue a rotation command signal Son. A cancel signal Sc is thereby issued from a signal generating circuit 82 to forcedly turn transistors 44, 33 into an OFF-state, and since housing position detecting switches 8, 9 are then in an On-state, the rotation command signal Son issued as above mentioned successively turns transistors 41, 30 into an ON-state. Thus a normal rotation control circuit 63 normally rotates driving motors 6, 7 to return the door mirrors 4, 5 to the housing position for dissolving the state of their collision.

Abstract: PURPOSE:To make it possible to detect a clutch pressure with a high degree of reliability at a low cost by incorporating a piston and a spring in a clutch hydraulic pressure control device so as to detect the motion of the piston in order to determine the presence of the clutch pressure. CONSTITUTION:A pressure detection switch 5 arranged in one end part of an oil passage 19 detects the clutch pressure, and is composed of a pressure detecting piston 30 and a spring 31 supporting the piston 30. When the clutch pressure exceeds a set value Th so that the clutch pressure pushes up the pressure detecting piston 30 overcoming the urging force of the spring 31, the upper surface of the piston 30 comes into contact with a cover 32. Accordingly, the presence of the hydraulic pressure in a clutch pack may be detected in the form of contacting and separating motion of the piston with respect to the cover 32. Accordingly, by detecting the presence of potential, it is possible to know the presence of the clutch hydraulic pressure as a reliable value at a low cost.
