Abstract:
A lower olefin producing catalyst which has high olefin production efficiency and maintains its activity for a long period of time when lower olefins are produced from an oxygen-containing compound, which is a solid catalyst used in producing lower olefins from an oxygen-containing compound, includes a solid-state catalyst component containing an MFI-type zeolite, in which, at a position where the shortest distance to the outer surface is maximum among all positions inside a structure of the solid catalyst, the thickness defined as a distance twice the shortest distance from the point to the outer surface is in a range of from 0.1 to 2.0 mm, and a method for producing lower olefins.
Abstract:
A multiplex router device, having a multiplex configuration, is instrumental in reducing internal and external traffic flows for a routing protocol process that occurs at a time of system switchover. A data base integration module, in a route calculation unit in the active mode, stores network link-state information collected by a routing protocol packet transmission-reception module in a link-state data base, and at the same time sends the information to a route calculation unit, but does not send routing protocol information collected. In the route calculation unit in the standby mode, a data base integration module that received the network link-state information stores its contents into its own link-state data base. When a failure occurs in the route calculation unit in the active mode, the route calculation unit performs the routing protocol process by using the stored link-state data base.
Abstract:

Abstract:
A signal processing device is provided with a plurality of signal processing circuits which are integrated on a monolithic semiconductor chip and which execute a plurality of predetermined signal processing stages. Signal input terminals are connected with predetermined one of the signal processing circuits for receiving input signals necessary for the plurality of signal processing stages. A first signal output circuit outputs the final signal processing result while a second signal output circuit outputs the intermediate processing results obtained from the signal processing circuits other than a signal processing circuit which performs the final stage signal processing. A plurality of selection circuits are respectively located on each of signal transfer paths for transferring the intermediate signal processing result to a succeeding signal processing circuit. Each selection circuit is provided with supplemental signal input terminals for externally receiving signals, respectively, and each of said selection can serve to select either of the intermediate signal processing result or the signal received at a supplemental signal input terminal on the basis of a predetermined control signal, with the selected signal being supplied to the succeeding signal processing circuit.
