摘要:
A method for manufacturing a III-V Group compound or a II-VI Group compound semiconductor element by VPE, comprising the step of annealing a grown compound at 400°C or higher, or electron beam irradiating the grown compound at 600°C or higher.
摘要:
Procédé d'oxydation de matières en présence d'un oxydant (28) et d'eau (22) à des températures supercritiques, permettant d'obtenir des matières d'énergie utiles et/ou plus avantageuses. On emploie des pressions comprises entre 25 et 220 bar. L'utilisation de températures adéquatement élevées permet d'obtenir dans un seul réacteur (31) à phase fluide, des vitesses de réaction rapide, une oxydation hautement efficace, ainsi que la précipitation de matières inorganiques.

An antihistamine, particularly diphenhydramine hydrochloride, for use in reducing the after-effects of over indulgence of alcohol. The antihistamine is administered to a person after the person has consumed alcohol.
摘要:
An electronic switch comprises a photosensitive semiconductor (1,11,12) and a light source (14,24) which, when actuated, illuminates the semiconductor and causes the latter to become conductive, the photosensitive semiconductor being a sintered mixture comprising, by weight, 58 - 72% of cadmium, 14.8 - 21% of selenium, 7 - 15% of tellurium, 7 - 12% of sulphur, 0.1 - 1% of chlorine, and 0.005 - 0.1% of copper.
摘要:
Hydrochloride 2,3,3a,4,5,6-hexahydro-8-cyclohexyl-1H-pyrazino (3,2,1-j,k)carbazol has formula (I). A method of obtaining the claimed composition consists in that 6-cyclohexyl-3,4-dihydrocarbazol-1(2H) is alkylated by hydrochloride β-(N,N-dibenzylamino) ethylchloride in a two-phase system: an aromatic hydrocarbon-34-40 %-aqueous solution of alkali in the presence of an interphase transfer catalyst at a temperature of 85-110 °C with subsequent hydrogenation of the resulting 6-cyclohexyl-9β-(N,N-dibenzylamino) ethyl-3,4-dihydrocarbazol-1(2H) over palladium catalyst on a carrier in the medium of a higher aliphatic alcohol at a temperature of 50-70 °C and under a pressure of 1 to 30 atm with subsequent transfer of the obtained 2,3,3a,4,5,6-hexahydro-8-cyclohexyl-1H-pyrazino (3,2,1-j,k)carbazol into hydrochloride and extraction of the latter. The claimed composition has an antidepressive action and is an active substance of a pharmaceutical preparation with antidepressive action.
