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.

摘要： Chilled coolant is prepared by liquid coolant utilizing the latent heat generated by a gasification of liquefied propylene, for example, and this chilled coolant is used in heat exchangers which are used in a process for production of acrylic acid or acrolein. This method allows effective utilization of the latent heat which used to be discarded and permits a reduction of energy consumption of cooling required separately in the step for production. By recovering the chilled coolant with the liquid coolant, it makes possible to stabilize the gasification of propylene, etc. and consequently stabilize the production of acrylic acid. This invention consists of providing the method for the production of acrylic acid, etc. and the apparatus which make effective use of the latent heat generated in the steps of production.
