摘要:
The method of isolating organic compound-degradable microorganisms included in this invention is characteristic in that microorganisms in the organic compound contaminated sample, for example an environment sample, are cultured in a carbon-free medium, at the same time, are contacted with organic compounds mainly as the gas phase, and selected by the tolerance to the organic compounds as the index. Also, the method for biodegradation of organic compounds is characteristic in that the microorganism thus isolated, for example, Komagatella brevis, is contacted with contaminated soil or contaminated underground water, and without the addition of additives or inducing substances for organic compounds decomposing enzymes, may effectively biodegrade the organic compounds in the environment.

摘要:
An image decolorizing apparatus decolorizing an image formed on a printed medium using a decolorable image forming material containing a color former, a developer, and a binder resin, has a scratching mechanism scratching the printed medium at a temperature lower than a softening temperature of the binder resin, and a heater heating a scratched surface of the printed medium to a temperature higher than the softening temperature of the binder resin.
摘要:
Disclosed is a method and an apparatus for soldering a base material. A binary solder essentially consisting of tin and a metal which can form an eutectic alloy with tin and which is exclusive of lead is prepared. The content of other metallic components is 0.1% by weight or less and the content of oxygen is 100 ppm or less. The binary solder is melted in a non-oxidizing environment and dispensed to the base material in an atmosphere in which the oxygen content is 2,000 ppm or less, to solder the base material with the binary solder. The soldering apparatus comprises an oscillator for supplying oscillatory wave energy having frequency of 15 KHz to 1 MHz to the base material. The soldering apparatus can also be realized in the form of a soldering nozzle or a soldering iron.
