A semiconductor laser device of the buried heterostructure type in which leakage current is substantially reduced. A mesa portion carries the active lasing portion of the laser, and current blocking layers are grown at either side of the mesa portion. One of the current blocking layers has its conductivity type inverted to the opposite type to eliminate a current leakage path, thereby to provide a...

A system and method for determining the anisotropy of a sample of a light transmitting sheet is disclosed. The surface of the sample is irradiated with a polarized light which is directed through the sample to an analyzer element. The polarizing plane of the analyzer is matched to, or maintained in a predetermined angular relation to, the polarizing plane of the polarized light. The sample is rota...

An arrangement for cooling a synthetic gas, generated in a gasification reactor, by means of a quenching cooler. The cooler is positioned below the outlet from the reactor and comprises a refrigerated inner jacket (5) surrounded by a pressurization jacket (1) and accommodating a water sump (6). There is an intermediate section (3) between the inner jacket and the outlet from the gasification react...

A method for manufacturing an electric resistance element first prepares carbon particles by thermally treating these particles, such as carbon black at a temperature of at least 300 DEG C. Then a separate mixture of the carbon particles in an epoxy resin is prepared by mixing the carbon particles with a solution of an amino resin to at least partially cause adsorption, occlusion or reaction betw...

An improved process for the production of a plasticizer containing dry, flowable polyvinyl alcohol (PVA) resin blend capable of thermoplastic processing. The process provides for the incorporation of plasticizers in an intimate contact with the PVA resin without heating, cooling, or extended drying steps. Specifically, PVA resin granules having an appropriately small particle size distribution are...

This invention concerns a process for the production of diesters by hydroformylation/Michael addition of alkyl acrylates, which comprises contacting the alkyl acrylate with carbon monoxide and hydrogen in the presence of a catalyst system comprising a rhodium-containing compound, excess phosphine-containing ligand, a nitrogen-containing compound and a solvent at a temperature of 70 DEG -150 DEG C...
