CONSTITUTION:A bubbler 1 is kept at a specified temperature. The flow rate of DMZ of organic metal among raw materials in MOCVD growing is controlled and sent into a reaction pipe 3 with H2, whose flow rate is controlled with a mass flow controller 2. H2Se and H2S, which are hydrides, are diluted with H2 into 10%. The flow rate of the hydrides are controlled with the controller 2 and sent into the reaction pipe 3. A GaAs semiconductor substrate 4 is set on a carbon susceptor 5 and heated to a growing temperature with a heater in said susceptor 5. A single crystal layer of ZnSSe is constituted with a changing layer, in which the maximum composition ratio of ZnS on the side of the GaAs substrate is 0.07 and the maximum composition on the side of ZnSe is 0.01. The growing temperature is 400-600 deg.C or less, which is higher than the growing temperature of the single crystal layer of ZnSe. Thus the effect of the mismatching of a lattice and the GaAs substrate is decreased, and the single crystal film of ZnSe characterized by high quality in chrystellography is obtained.

IPC: F28D7/16
Filed: 1982-10-19
Abstract: PURPOSE:To obtain a heat exchanger capable of eliminating cleviated flow at the initial stage and thereby reducing the pressure loss, by disposing baffle plates having different surface areas and spaced inequally from each other in a plurality of stages concentratedly at an upper and a lower portions of a tube bundle section, and disposing grid-like baffle plates at the central portion of the tube bundle section. CONSTITUTION:Cooling medium introduced from an inlet nozzle 15 on the side of the casing is passed through a flow regulating vane 16 and carried into the central portion from an inlet port section 11. Then, the cooling medium is passed between cross-flow baffle plates 13 and carried toward lattice-like baffle plates 14 disposed at the central portion. Thereafter, the cooling medium is passed again through cross-flow baffle plates 13 and then discharged to the outside from an outlet port section 12. By disposing these cross-flow baffle plates concentratedly at an upper and a lower portions of a tube bundle section 10, it is enabled to prevent the influence of channeling on the side of the casing from being exerted toward the central portion of the casing and to eliminate channeling at the initial stage. Further, since grid-like baffle plates are disposed at the central portion of the tube bundle section 10, the flow of cooling medium is made parallel on the side of the casing, so that the total pressure loss at the tube bundle section 10 can be reduced. With such an arrangement, it is enabled to eliminate the deviated flow of cooling medium at the upper and lower positions of the tube bundle section while preventing the influence of deviated flow from being exerted toward the central portion of the casing, to reduce the temperature difference between heat exchanging substances, and to prevent buckling of heat exchanger tubes effectively.

Abstract: PURPOSE:To reduce vibration and stress which are caused at the time of grinding by tilting the axial line in the joint part of a pressure frame and a roller bracket for the upper face of a grinding ring. CONSTITUTION:Grinding ring 1 is rotated at the time of grinding and a roller 2 is stationarily rotated on the grinding ring 1 in accordance therewith. The material to be ground is crushed between the roller 2 and the grinding ring 1. When the roller 2 is shaked to the lateral direction B by impact caused in this crushing, the roller 2 and a roller bracket 3 start to be rotated around a pin 4. At this time, radius of rotation of the roller 2 around a pin 4a in a point E is YE. Radius of rotation around a pin 4b in a point F is gammaF. Radius of rotation of the roller 2 around a pin 4 becomes gammaE>gammaF. Further since the roller 2 is stationarily rotated on the grinding ring 1 in accordance with rotation of the grinding ring, frictional force F of the grinding ring 1 and the roller 2 is caused in the roller 2. Thereby stress and vibration in the grinding part are drastically reduced.
