Title: Decomposition of trihalomethanes
Inventor: SAKAI WATARU
IPC: C12N1/20
Filed: 1989-04-15
Abstract: PURPOSE:To efficiently decompose trihalomethanes by culturing microorganisms of the genus Pseudomonas having the decomposition capacity of trihalomethanes in an inorg. liquid medium containing trihalomethanes in waste water at the optimum temp. under the optimum pH condition. CONSTITUTION:Bacterial of the genus Pseudomonas are subjected to shaking culture in an inorg. liquid medium (containing ammonium chloride, dipotassium phosphate, potassium chloride, ferrous sulfate, yeast extract, magnesium sulfate or the like as nutrient sources) containing trihalobmethanes (trichloroethylene, trichloroethane, tetrachloroethylene, chloroform or the like) contained in waste water at about 25 to 30 deg.C and pH of about 7 to 9.

Title: Field-effect transistor
Inventor: MEGURO TAKESHI
IPC: H01L29/778
Filed: 1989-04-17
Abstract: PURPOSE:To stabilize the interface of a substrate and a buffer layer, and to obtain a PET having excellent electrical characteristics and high quality by forming a second buffer layer shaped through a vapor growth method between the compound semiconductor substrate and the buffer layer. CONSTITUTION:A second buffer layer 3 formed through low-temperature growth at a temperature lower than 600 deg.C is interposed between an undoped semi- insulating compound semiconductor substrate 4 and a buffer layer 2. Consequently, even when the storage of carriers and the generation of an electron trap are generated on the interfaces of the substrate and the buffer layer by the effect of the semi-insulating substrate, the second buffer layer 3 inhibits the generation of a surface thermal conversion layer while conducting P-N compensation in low carrier concentration, thus compensating the storage of carriers and the trap. Accordingly, the buffer layer is not subject to the effect by the compound semiconductor substrate, and stable interfaces are acquired between the substrate and the buffer layer, thus obtaining a FET having high quality.
