Abstract: A server system constructed by a network using a known PBX in such a manner that information processing terminal equipment and server devices are held in normally-used extensions of the PBX together with other terminals such as telephones, facsimiles, etc. Logical channel numbers of packet links between the PBX and the information processing terminal equipment are assigned to electrically-connected server devices in association with each other and sent to users. The users sends server use data to corresponding destinations by data packets to which the logical channel numbers are applied. The PBX performs a packet exchange process such that the logical channel numbers are respectively associated with physical addresses of the server devices. If the PBX regards the users as improper users, then it does not inform the users of the logical channel numbers.

Abstract: Ultrafine powder is stored in a pneumatic transportation tank (20), and is discharged to a transporting conduit (23) while being fluidized by the pressurized air fed through a fluidizing air port (24). The ultrafine powder is fed to a weigher (30) provided at the other end of the transporting conduit (23), at which the weight of the transported ultrafine powder is weighed by a load cell (31). After the weighed value reaches 90% of a predetermined value, the fed amount of the pneumatic transportation air is reduced, and a bypass regulating valve (38) is adjusted to thus decelerate the transportation. When the weighed value reaches 100% of the predetermined value, the discharge of the ultrafine powder to the transporting conduit (23) is stopped. This method and the apparatus enable the storage, quantitative batch transportation, and automatic weighing of the ultrafine powder such as silica fume.

Abstract: An ISDN communication controller or a multi-circuit communication controller is implemented in a sheet of communication adapter board. For each channel or circuit, a dedicated subprocessor section conducts communication processing. In each subprocessor section, a local bus is disposed to connect a CPU, a serial controller, and an RAM. In a main processor section controlling the subprocessors, a local bus is employed to connect a CPU, an RAM, and an ROM. In a system processor section exclusively achieving information processing, a system bus is used to connect a CPU and a main memory. The local buses are connected via respective controllers to an upper-level local bus. A shared RAM is connected via a controller to the upper-level local bus and the system bus. The controllers of the subprocessor sections translate addresses to be outputted from the main processor section to the upper-level local bus to supply translated addresses to the respective local bus.
