A switching center 30 comprises a memory part M2, a memory part M3, and a memory part M4. The memory part M2 stores a terminating terminal number corresponding to and registered by each subscriber. The memory part M3 stores idle/busy information corresponding to each terminal. The memory part M4 stores idle/busy information corresponding to each subscriber. When a subscriber 11.sub.1 makes a call at a terminal 12.sub.2, the switching center 30 determines whether the idle/busy information for the subscriber 11.sub.1 stored in the memory part M4 is idle or busy. When the idle/memory information represents idle, the switching center 30 refers to the idle/busy information for the terminal 12.sub.2 stored in the memory part M3. When this idle/busy information represents idle, the switching center 30 reads out the terminal number of a terminating terminal of a terminating subscriber stored in the terminating terminal memory part M2 and performs an outgoing call connection process. At this point, the switching center 30 also sets the idle/busy information for the subscriber 11.sub.1 and the terminal 12.sub.2 to busy state. When the subscriber 11.sub.1 makes a call, while the terminating terminal 12.sub.1 is performing an incoming call connection process for the subscriber 11.sub.1, since the idle/busy information for the subscriber 11.sub.1 has been set to the busy state, even if the terminal 12.sub.2 is idle, the switching center 30 does not perform an outgoing call connection process for the subscriber 11.sub.1 at the terminal 12.sub.2.

In order to provide a packet transfer scheme in which various data can easily be used commonly with other communication methods and a packet can be transferred at a high speed, a mobile communication system comprises a database (20) for storing an identification number of a mobile terminal (40) and location information indicating a zone in which the mobile terminal is currently located, a packet switch (10), and another packet switch (30) capable of communication when the mobile terminal (40) is located in a zone under the packet switch (30). The packet switch (10) inquires of the database (20) about the location information of the mobile terminal (40) when the packet switch (10) receives a packet addressed to the mobile terminal (40). When the mobile terminal (40) is located in the zone under the packet switch (30), the packet is transferred to the mobile terminal (40) through the packet switch (30). Owing to this arrangement, the number of packet switches necessary for transferring the packet to the mobile terminal is two at the most. Thus, the packet can be transferred rapidly.

In the case of passing a reagent in a reaction channel in a microchip, which carries a reactant capable of reacting with the reagent on the wall thereof, and bringing the reactant into contact with the reagent so as to carry out a reaction, the reagent is efficiently passed to the reactant to thereby promote the progress of the reaction. In carrying out the reaction as described above, the reagent (30a) is passed in such a manner that the periphery of the gas/liquid interface at the front end of the reagent moves forward and backward along the wall face of the reaction channel (10). After the completion of the reaction between the reagent (30a) and the reactant, another reagent (30b), which is to be reacted with the reactant capable of reacting with the reagent that is carried on the reaction channel, is passed into the reaction channel (10) while providing a gas in the front edge side thereof. In carrying out the reaction, the reagent (30b) is passed in such manner that the periphery of the gas/liquid interface at the front end of the reagent moves forward and backward along the wall face of the reaction channel (10).

A micro-reactor for analyzing a sample, comprises (1) a plate-shaped chip; (2) a plurality of regent storage sections each having a chamber to store respective agents; (3) a regent mixing section to mix plural regents fed from the plurality of regent storage sections so as to produce a mixed reagent; (4) a sample receiving section having an injection port through which a sample is injected from outside; and (5) a reacting section to mix and react the mixed regent fed from the reagent mixing section and the sample fed from the sample receiving section. The plurality of regent storage sections, the regent mixing section, the sample receiving section and the reacting section are incorporated in the chip and are connected through flow paths, and the regent mixing section includes a feed-out preventing mechanism to prevent an initially-mixed regent from being fed out to the reacting section.

摘要:
A microreactor capable of reaction between a sample and a mixed reagent containing a mixture of multiple reagents, which microreactor avoids the interposition of air between driving solution and reagents and realizes high-precision controlling of the timing of mixing of reagents and other liquids, the mixing ratio of liquids, the pressure for liquid feeding, etc. Further, there is provided a method of liquid feeding making use of the same. Accordingly, a flow path branched at the position of an inlet from a flow path through which an opening communicating with an external pump communicates with the inlet is provided with an air evacuation flow path with its terminal open outward. Further, the flow path resistance of the air evacuation flow path for a liquid is made greater than the flow path resistance, for the liquid, of a flow channel from the reagent storage chamber to a reagent feed-out flow path.
