Abstract: A GaAs monocrystal film was grown by use of a process which comprises introducing a gaseous compound containing a component element desired to be grown into a vacuum tank, and submitting the compound to reaction on a base to thereby grow a semiconductor crystal each one molecular layer.Triethylgallium (TEG) and arsine (AsH.sub.3) are used as the gaseous compound. One gas is introduced into the vaccum tank and then discharged after the passage of a predetermined time, and the other gas is introduced thereinto and then discharged after the passage of a predetermined time whereby a crystal for one molecular layer grows.By use of TEG as a gallium source, reaction progresses even when a temperature of the base is below 300.degree. C., and a GaAs monocrystal film which is extremely less in lattice failure and impurities was obtained.

Abstract: A method for growing a single crystal thin film of an element semiconductor which comprises repeating the successive operations of feeding a single kind of gas containing the element semiconductor as a component element onto a substrate heated in a growth chamber and then exhausting the gas in the growth chamber under controlled conditions and thereby growing the single crystal thin film of said element semiconductor in a desired thickness with a precision of monomolecular layer. In an alternate method for growing a single crystal thin film of an element semiconductor, the sole gas containing the element semiconductor is continuously fed onto the substrate for a given period of time, thereby forming a single crystal thin film of element semiconductor having a desired thickness. According to the present invention, there can be obtained single crystal thin films with high quality in a high reproducibility, by simplified operating parameters and growing apparatus.

Abstract: A method of manufacturing a surface-emitting-type semiconductor laser device having a buried structure. A GaAlAs film is used as a mask layer in forming a GaAlAs/GaAs system burying part around a GaAlAs/GaAs system buried part. The mask layer can be formed continuously together with an active layer, a cladding layer and the like which constitute the buried part by means of a crystal growing apparatus for forming the buried part. When the system is etched, the GaAlAs film mask prevents the system buried part from becoming undercut so that the mask has better resistance to peeling during subsequent processing.

Abstract: A light propagation region is divided into a plurality of subregions, each subregion being limited within a minimum spatial resolution unit where an interference occurs between discrete points, and a 0-order diffraction pattern of a Fraunhofer diffraction image is detected If a convex lens and either a pinhole or an optical fiber which is disposed on a focal plane of the convex lens are employed and the diameter of the pinhole or the core diameter of the optical fiber is set to be not greater than the first dark ring of a Fraunhofer diffraction image produced by the convex lens, it is possible to take out the greater part of the energy of a plane wave component that enters the lens from a predetermined direction and remove other components from different directions, i.e., scattering component. If a plurality of optical systems of this type are bundled together, only a plane wave with a one- or two-dimensional intensity distribution can be taken out with high brightness and high resolving power.

Abstract: A rotating impeller for stirring liquids contained in tanks. Strip-like blades of simple form radiate from a central hub, in swept-back configuration relative to the direction of rotation. The blades are angled relative to the hub so as to exert a forward and downward force upon the liquid as the impeller rotates, and the blade curvature is such that the area projected upon the liquid by the solid structure of the rotating blade is less than the corresponding area that would be projected by an otherwise similar blade in which imaginary straight lines connected all adjacent vertices, and any void areas lying within the boundaries of those imaginary lines had been filled in. The preferred arrangement of the blades is such that when the impeller is arranged with its axis vertical, curvature of each blade along its length is such that it extends away from the hub in a diminishing downward curve, reaches a lowest point, and then rises again before the blade tip is reached.
