摘要:
A mobile unit transmits a request for position registration to a network when moving from a first area to a second area. When the number of incoming calls does not exceed a threshold and the number of movements between the first area and the second area exceeds a threshold, a mobile switchboard combines the first area and the second area into an extended area, and informs the mobile unit of the extended area.

A rotor of an induction starting synchronous motor includes permanent magnets and induction coils having both ends short-circuited in a core. The permanent magnets are arranged side by side in a longitudinal direction of the core to form a plurality of sets of permanent magnets. Two sets of the permanent magnets form respective poles of the induction starting synchronous motor. The two sets of permanent magnets forming each of the poles are located inclined or slightly shifted in a cross-sectional plane of the core by rotating the two sets of permanent magnets about corners of the permanent magnets nearest the induction coils as rotating axes into directions such that magnetic fluxes induced by the two sets of permanent magnets are cancelled each other. With this construction, the induction starting synchronous motor can be smoothly started and operated with improved power factor and efficiency characteristics. A slot for receiving the two sets of permanent magnets is preferably formed at its mid portion with a protrusion and a cavity so as not to permit the permanent magnets to contact each other.

An electronic circuit substrate excellent in reliability, which comprises a porous ceramic sintered body with film devices such as a conductive circuit, a resistor and a capacitor directly formed on a surface thereof. A resin is filled in the pores of the porous ceramic sintered body, and the bottom surface of the film devices are fit into the pores and recesses on the surface of the porous ceramic sintered body in close contact therewith in a wedged state. A method of producing the aforesaid electronic circuit substrate comprises the steps of forming film devices directly on a surface of a porous ceramic sintered body. Then, filling the pores of the porous ceramic sintered body with a resin so as to fit the under surface of the film devices into the pores and recesses on the surface of the porous ceramic sintered body in close contact therewith in a wedge state.

In a communication system in which a plurality of processing apparatuses are communicably connected to one another over a network, a processing apparatuses has an update request issuing unit issuing an update request containing address information to be updated in order to update an address book and an address book updating unit updating the address book on the basis of a response result to the update request, a determining unit determines whether or not the address information contained in the update request is valid when receiving the update request from the processing apparatus, and a response result transmitting unit transmits a result of determination made by the determining unit to the processing apparatus as the response result to the update request. The address book of the processing apparatus retaining the address information about other processing apparatuses can be updated to the latest state, with certainty.
