IPC: H04L12/721
Filed: 1994-11-25
Abstract: PURPOSE: To secure service quality Q by receiving a reservation signal to be transmitted by a line for reservation that a mobile station selects according to desired service quality Q and controlling the transmission of the transmission packet from a mobile station to a communication line according to the quality Q by a base station. CONSTITUTION: The up and down channels (ch) of a base station and a mobile station are provided with (D/R) channels for data/reservation and priority/normal (RH, DH/RN, DN) channels that these channels are further divided according to service quality Q. When the mobile station transmits a packet to the base station, a reservation signal is transmitted to the base station via the RH or RNch selected according to desired quality Q. The base station transmits the transmission packet from the mobile station to the DH or DN by a control according to the quality Q corresponding to the RH or RNch where the received reservation signals are normally transmitted. Thus, the quality Q to be required is satisfied, the control load of the base station discriminating the quality Q can be reduced, and each service quality can be secured at the time of high traffic.

Title: Method for improving durability of catalyst for oxidizing unburned hydrocarbon in exhaust gas
Inventor: YAMAMOTO HIROMICHI
IPC: B01D53/86
Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To improve the durability of the catalyst for oxidizing unburned hydrocarbon by previously removing a sulfur component from fuel before burning the fuel forming the waste gas in the case that exhaust gas is treated with a catalyst oxidizing the unburned hydrocarbon in exhaust gas with excessive oxygen and constituted by supporting platinum and palladium on alumina. SOLUTION: The fuel gas such as city gas is supplied to a dilute combustion gas engine C from an introducing pipe A together with the air from a combustion air introducing pipe B, and the gas formed after combustion is discharged from a conduit D. And the trace hydrocarbon in the waste gas from the conduit D is oxidized at an oxidizing catalyst layer and discharged from a discharge part F and sent to a heat recovering stage. In such a case, when the sulfur component is to be removed from the fuel supplied to the dilute combustion gas engine C, a desulfurization device X is disposed in the fuel introducing pipe A. Then the sulfur-containing compd. such as odorant incorporated in the fuel such as city gas is removed at the desulfurization device X.  The activated carbon, the zeolite, etc., effective for removing the sulfur- containing compd. are exemplified for example as the desulfurization agent used at the desulfurization device X.
