Title: Combustion of coke
Inventor: SATOU MASAYUKI
IPC: F23C1/02
Filed: 1982-08-27
Abstract: PURPOSE:To improve the combustion efficiency of coke, by adding a general fuel oil such as waste oil or heavy oil to coke. CONSTITUTION:Coke, whereto heavy oil is added, has combustion starting temperature and completion temperature, which are respectively moved by about 30-50 deg.C to the low temperature side compared with simple coke, and in case of heavy oil being added to coke, the firing speed of coke is increased, and a burnout speed is also increased. Thus, when the mixture of coke and heavy oil is charged into a combustion furnace for incineration, the amount of combustible content burnt at the same combustion temperature is apparantly increased compared with that of coke in the case of simple coke, thereby the combustion efficiency of coke can be improved.

Title: Multi-layer indium-contained nitride buffer layer for nitride epitaxy
Inventor: KERN R SCOTT
IPC: H01L21/20
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device wherein a cracking due to doping and composition fluctuation is prevented. SOLUTION: A semiconductor device comprising an active structure comprising a substrate, a buffer structure or nucleus generation structure, and a circuit element. The nucleus generation layer is manufactured at a relatively low temperature and comprises at least one layer of an III-V group nitride compound comprising indium. At least one layer (the one directly deposited on a substrate is preferred), of a multi-layer structure, is made of an indium-containing III-V group nitride compound, acting as a buffer layer 16. The indium-containing layer is relaxed with a succeeding AlInGaN epitaxy. As a stress and crack are reduced, the flexibility in composition and doping adjustment is improved.  Since the electrical and optical characteristics of a device is decided by the stress and distortion condition in the active structure, the composition and layer-pressure of the nucleus generation layer are adjusted to design the characteristics to a target. An indium-containing nitride of high quality is effectively grown at a relatively low temperature.

Abstract: PURPOSE:To make it possible to emit an amplified light signal outside of a substrate by optically coupling the light signal propagating in an optical waveguide to a semiconductor light emitting element and putting this semiconduc tor light emitting element into a light emitting state. CONSTITUTION:The optical waveguide 4 composed of a core layer 2 and a clad layer 3 is formed on the substrate 1. A semiconductor laser 10 is so fixed onto such optical waveguide 4 (core layer 2) that the semiconductor substrate surface is brought into contact therewith. The light refractive index of the semiconductor substrate of the semiconductor laser 10 is set higher than the optical refractive index of the optical waveguide 4. As a result, the light signal propagating in the optical waveguide 4 is optically coupled to the semiconductor laser 10 of the high light refractive index arranged thereon. Further, laser oscillation is generated by the light signal entering from the optical waveguide 4 and the laser beam is emitted in the surface direction when a bias current to the extent of obviating the oscillation is kept passed between electrodes. Namely, the light signal amplified in the light intensity is emitted outside of the substrate.
