Title: Article formed of improved superlattice quantum cascade laser
Inventor: CAPASSO FEDERICO
IPC: H01S5/343
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To use a unit which is effective for monitoring contamination by collecting multiple identical repetitive units so as to form a waveguide core area, and constituting the repetitive units of injector areas and superlattice active regions. SOLUTION: A waveguide core region 13 is formed between a substrate/ lower-order optical close region 12 and a higher-order optical close region 14. The waveguide core area 13 is constituted by gathering multiple identical repetitive units. The repetitive units are constituted of injector regions which are injection/relief areas and superlattice active regions selected so that radiative carriers from a higher-order energy level to a lower-order energy level in the superlattice active region can easily be shifted. Thus, the diffusion of the carriers becomes less, an optical loss can be reduced, and the unit can used effectively be for monitoring of contamination.

Title: Manufacturing of preform for optical fiber
Inventor: MITANI MAKOTO
IPC: G02B6/00
Filed: 1994-06-06
Abstract: PURPOSE:To obtain an optical-fiber preform free from difference or refractive indexes distribution between axial direction and radial direction by supplying a fluorine compound together with a raw material and subjecting them to oxyhydrogen-flame hydrolysis to produce a fluorine-containing porous preform and subsequently subjecting the obtained product to fluorine-doping process in the same furnace. CONSTITUTION:In a reaction furnace 24, while a rotating bar 21 connected with a quartz bar 23 is rotated at a specified speed, a fluoride gas is supplied from a multilayered burner 22 together with a raw material, hydrogen and oxygen in such a manner that the flow of the outer layer is 1-5 times of that of the inner layer. By this process, a fluorine-containing porous preform 25 is synthesized by oxygen-flame hydrolysis. Subsequently, the raw-material supply is stopped, the flow of the fluoride gas is increased to 1.5-5 times and under these conditions the obtained fluorine-containing porous preform 25 is further subjected to fluorine- doping process in which the preform 25 is treated with a fluorine-containing dope. By this process, the fluorine content in the porous preform 25 is homogenized and accordingly the refractive index distribution in an axial direction and in a radial direction of the optical-fiber preform is homogenized in the range of 0.01-0.3 in terms of a specific refractive index DELTAn<-> against quartz. Following vitrifying process is performed in a conventional manner.

Abstract: PURPOSE:To prevent an outflow of cutting fluid to outside a chip box from scattering, by providing a fluid chamber, which supplies fluid of low pressure, and a pressure opening hole in the chip box in an opposite side to a work, in the case of a cutting machine by a gun drill or the like. CONSTITUTION:If high pressure cutting fluid is supplied to a machined part by a tip 8a in the point end through a circulating hole 10 in the center of a tool 8 of a gun drill or the like, generated cutting chips, mixing in the cutting fluid, are discharged into a chip box 7 through a groove 11. A device provides a fluid chamber 12, which supplies cutting fluid 18 of low pressure from a supply port 17, in the rear part of said chip box 7. The cutting chip, discharged along the groove 11, is prevented from flowing due to mixing in said cutting fluid 18 of low pressure further discharged into the chip box 7 from an opening hole 13. Accordingly, the device prevents an outflow of the cutting fluid, which passes through the chip box 7 to a holder 2 along the tool 8, from scattering by centrifugal force.

Abstract: PURPOSE:To make it possible to reuse respectively separated components as resources by a method wherein a film-shaped resinous sheet whose shape can be varied arbitrarily is provided in the surroundings of a gap to foam a heat insulator, so that the heat insulator is poured into the sheet to be foamed. CONSTITUTION:A resinous sheet 8a and 8b is sandwiched between an inner vessel 4 and a heat insulator 5 and between an outer coat 6 and the heat insulator 5 respectively. In this instance, at an upper of a heat storage vessel 1, an outer surface of an upper end of the inner vessel 4 and a bending part 6a of the outer coat 6 are combined directly without interposing the heat insulator 5, but only sandwiching the sheets 8a and 8b.

Thus the heat insulator 5, the inner vessel 4 and the outer coat 6 contact necessarily through the sheets 8a and 8b. Accordingly, the inner vessel 4 can be separated easily from the sheet 8a, the outer coat 6 from the sheet 8b, and also both from the heat insulator 5.

Abstract: PURPOSE:To promote reaction for crystallizing and separating impurities from molten aluminum as intermetallic compound and to effectively utilize the crystallized intermetallic compound. CONSTITUTION:Fine grains of the intermetallic compound having the same composition as that of the intermetallic compound crystallized from the molten aluminum raw material 1 are added into the molten aluminum 1 to promote the crystallizing reaction of the intermetallic compound in a crystallizing vessel 2.

The molten aluminum 6 is returned to the crystallizing vessel 2 and the floated and suspended fine granular intermetallic compounds are used for the crystallizing and separating reaction of the impurities. As the intermetallic compound having the same composition as that of the intermetallic compound crystallized from the molten aluminum raw material 1 is used as nucleus of crystallizing growth, the impurities are efficiently crystallized and separated. Further, the coarse granular intermetallic compound is consumed as the raw material for producing the aluminum alloy.
