    摘要: A communication terminal, in case that transmission/reception of a frame is carried out between a management terminal and another communication terminal, reads out its frame content, and on the basis of a content of the frame which was readout, sets up power off time for turning off power of the communication terminal, and turns off power of the communication terminal, during a period of the power off time. By this means, depending on a content of a frame which is transmitted/received between another communication terminal and the management terminal, power off time of the communication terminal is calculated, and therefore, it is possible to turn off power of the communication terminal during such a period that transmission/reception is not carried out to/from the management terminal, and it is possible to suppress power consumption of the communication terminal.

In the exchange of heat of an easily blocking substance by the use of a plate type heat exchanger, a method for preventing the plate type heat exchanger from blockage is disclosed which has the plate type heat exchanger provided in the port for introducing a gas containing an easily blocking substance with a gas dispersion plate. This invention, in the heat exchange of an effluent gas emanating from a process for the production of (meth)acrylic acid or an ester thereof or the disposal of the gas, significantly allays blockage of the interior of the plate type heat exchanger.

    摘要: The present invention provides an improved process for production of acrylic acid by subjecting propylene and/or acrolein to catalytic gas-phase oxidation with a molecular oxygen-containing gas. In the process, the mixed gas obtained by the catalytic gas-phase oxidation is contacted with an aqueous collecting agent containing acrylic acid, acetic acid and a poorly-soluble-in-water solvent, to form an aqueous acrylic acid solution; and the aqueous acrylic acid solution is subjected to azeotropic distillation in the presence of a poorly-soluble-in-water solvent to remove by-products and obtain high-purity acrylic acid.
