Abstract: PURPOSE:To make it possible to always project laser beam to a vertical direction, by mounting reflective mirrors on the suspension plates suspended from the ceiling surface of a container by two pairs of suspension systems and reflecting laser beam from a beam projector to an upward vertical direction by said reflective mirrors. CONSTITUTION:The protection lines of suspension lines 10a, 10c and 10b, 10c of one of each pair among two pairs of suspension lines are respectively superposed and become left and right symmetric. These projection lines intersect at the upper parts thereof and the width Z of the mount points to the ceiling surface 2a of the suspension lines is set so as to be extremely small as compared with the width (y) of the mount points to a suspension plate 8. By this method, even when a container 2 is inclined by about 0-10 deg., the suspension plate 8 is held to an almost horizontal direction. Therefore, the inclination of a first reflective plate 16 to that of the container in this plane does not change and laser beam L1 is always injected to a vertical direction.

Then, after the residual gas is eliminated completely by evacuation, if a gas B composed of phosphorus trichloride and hydrogen is supplied, phosphorus trichloride reacts with the adsorbed trimethyl indium and makes InP crystal of one molecule layer grown on the substrate surface and, at the same time, methyl chloride is produced as reaction product D. Then the residual gas and the reaction product D and eliminated completely by evacuation. This cycle of one molecule layer growth is repeated until the thickness of the crystal C reaches a required value.

Filed: 1979-05-10
Abstract: PURPOSE:To prevent knocking in an efficient manner by detecting the knocking by a knocking sensor and by switching the comparison level of a comparator in accordance with engine speed. CONSTITUTION:When a knocking is detected by a knocking sensor 7, an output of the F-V converter 6 is fed to an output terminal X of an analog-multiplexer 8.
