摘要： This invention discloses a semiconductor laser capable of a high temperature and high output operation by forming a mesa stripe having an active layer in a reverse triangular mesa shape and forming thick semiconductor layers on both sides of the mesa stripe in such a manner that the resulting p-n junctions have a current blocking function. The invention discloses also a semiconductor laser wherein the formation of the p-n junctions described above is made before the formation of the reverse mesa stripe, and ion implantation is introduced in order to form the p-n junctions. Furthermore, the invention relates to transistors and semiconductor lasers using InGaAsP type quaternary compounds as the semiconductor. The quaternary compounds having a composition in which an energy band gap is from 1.2 to 1.4 eV are formed in a thickness of up to 1 .mu.m, and there can be thus obtained semiconductor devices having a small leakage current and being stable with time.

摘要： The present invention relates to a semiconductor laser which oscillates in a single longitudinal mode and with a low threshold current and which exhibits a good mode stability against reflected light, and provides a structure of a distributed feedback semiconductor laser with modulation for a gain. The structure is such that gain producing regions are periodically arranged and that a substance transparent to laser radiation is buried between the regions. A layer including the gain regions is formed of a superlattice layer, and an impurity is diffused or implanted into periodic positions of the layer, whereby the transparent regions and the gain regions with little lattice damages can be readily formed.

摘要： A primary corona charging unit (13) applies a uniform electrostatic charge to a photoconductive drum (12) prior to radiation of the drum (12) with a light image of an original document (26) to form an electrostatic image. The electrostatic image is developed and transferred to a copy sheet (31) by use of a corona transfer charger (14) and separation charger (16). An A.C. corona discharger (17) discharges the drum (12) prior to recharging by the primary charger (13). The primary charger (13) is de-energized prior to the end of a copying operation to prevent charging of non-image areas of the drum (12). The copying operation is terminated by stopping rotation of the drum (12) and simultaneously de-energizing all of the other corona chargers (14), (16), (17). At the beginning of a copying operation, the corona chargers (14), (16), (17) are energized simultaneously with starting rotation of the drum (12). The primary charger (13) is not energized until sufficient time has elapsed for the leading edge of a portion of the drum (12) charged by all of the other chargers (14), (16), (17) to reach the primary charger (13).

摘要： The image density adjustment method for use in electrophotography in which, when the image density of a copied image is decreased below a standard image density, the development bias-potenial is increased while the exposure to be applied to a photoconductor is kept constant. When the image density of a copied image is increased above the standard image density, the exposure is decreased while the development bias voltage is kept constant. Thus, the image density of a copied image can be adjusted as desired to minimize the effect of light fatigue of the photoconductor.

摘要： A spent nuclear fuel is reprocessed by dissolving a spent nuclear fuel in an aqueous nitric acid solution and separating and recovering nuclides contained in the resulting fuel solution by solvent extraction. A spent nuclear fuel reprocessing method includes: an electrolytic valence adjustment step in which nuclides contained in the fuel solution is electrolytically reduced without removing fission products or minor actinides until valence of plutonium is at a level at which solvent extraction efficiency is low by using the valence of plutonium contained in the fuel solution as a parameter; and a nuclide separation step in which, by using an extraction solvent which extracts uranium contained in the fuel solution, uranium is distributed from the fuel solution subjected to the electrolytic valence adjustment step to the extraction solvent.
