    摘要： Disclosed are a method and an apparatus for removing methane from a gas which contains the methane at such a low concentration as not to be rendered into a combustible range with whatever ratio of air mixed therewith. In order to ensure satisfactory methane removal performance even in the coexistence of sulfur compound and in order also to provide stable methane removal performance for an extended period of time without performance deterioration even when the methane concentration varies significantly, the gas is fed to a heat exchanger for preheating and methane is exposed to an oxidation catalyst which oxidizes the methane through contact therewith. Then, the resultant gas is fed again to the heat exchanger for heat recovery through heat exchange with un-reacted gas. Further, the flow rate of gas to be treated is varied, according to a concentration of the methane contained in this treated gas.

    摘要： A first diode is connected in series to a transmission port, and a low pass filter having transmission band and reception band as passing band is disposed between the first diode and an antenna port. A second diode is connected between the reception port and the ground. A phase shifting function is provided between the first diode and a reception port, having reception band as passing band, so that the impedance as seen from the first diode to the reception port side is almost open in the transmission band when a current flows in the second diode.

    摘要： When a transmit station pages a pager which has the paging area of that transmit station as its local area, it pages using an address which is unique in that area. When a pager with another local area has moved into this paging area and is paged, it is paged using the area identification number of its local area and the address of its receiver. Each pager can therefore be paged in any given paging area without having to be given a separate address for each paging area.
