摘要： A narrow-band oscillation excimer laser that can be suitably used as a source of light of a reduced projection exposing device for producing semiconductor devices, and a wavelength detector. In this laser, the direction along the lines of the grating is brought nearly into agreement with the direction of beam expansion by a prism expander, and a polarizer element is disposed in an optical resonator to selectively generate linearly polarized waves nearly in parallel with the direction of beam expansion. Further, a rear-side or a front-side window in a laser chamber is so arranged that a Brewster's angle is nearly obtained with respect to an ooptical axis of the laser within a plane defined by the direction of beam expansion and the optical axis. Moreover, on one surface of the prism constituting the prism beam expander is formed a reflection-preventing film that selectively prevents the reflection of only the polarized component which is nearly in parallel with the direction of beam expansion. The device for detecting the wavelength of the narrow-band oscillation excimer laser permits reference light emitted from a reference source and light to be detected to fall on an etalon, introduces light through an etalon to an optical system for converging the light to form an image on the detecting surface of a light detector, and determines the wavelength of the laser beam from the interference fringe detected by the light detector.

摘要： This invention is directed to provide a balanced cargo handling apparatus and its control method which can rapidly bring a suspended work to halt when an operator releases his hold of the work even if there is some error in the stored weight value of the work. The balanced cargo handling apparatus includes in its operation circuit (17) a position mode operation unit (19) which keeps an operation mode in a position mode during a shift from a lever mode directed by a speed instruction (R) from an operation lever (8a) to a balance mode for accomplishing an equilibrium state of the work (5). When any abnormality such as one after a rapid change in load acting on the work (5), an abnormality mode operation unit (23) is additionally disposed in the operation circuit (17) so as to stop the work in the position in which it was first positioned with the work not swaying. A judgement circuit (24) is disposed separately in order to output a mode change-over signal in accordance with each input signal (V, X, R, FL, a) to the mode selection circuit (21) for selecting each mode. A judgement circuit (27) for judging a mode at the time of abnormality is contained in this judgement circuit.

摘要： A driving control device and a control method therefor suitable for industrial vehicles, particularly for construction vehicles such as a hydraulic power shovel, which makes it possible for a driver to drive a vehicle in a desired direction easily without any illusion. To accomplish this object, the method of the invention comprises tilting a driving lever in a desired driving direction, detecting the angle of the operation direction by a lever angle detector, detecting a relative angle of rotation between an upper swivelling member and a lower driving device by a car body swing encoder, sending these signals to a controller, judging the swinging direction of the lower driving device through the calculation by the controller, sending then the output signal to a driving operation valve to swing the lower driving device without travelling, stopping it when the lower driving device becomes parallel to the operation direction of the driving lever, and moving straight the lower driving device in the operation direction of the driving lever. The angle of the operation direction of the driving lever and its tilt angle may also be detected by the lever angle detector and then the lower driving device may be swung without travelling at a speed proportional to the tilt angle of the operation lever or may be moved straight. Furthermore, the lower driving device may be swung without travelling and driven by detecting the angle between an upper swing body and the direction of north of terrestrial magnetism by a gyrocompass.
