摘要:
A mobile communication system in which a mobile station copies data and transmits that copied data to a plurality of base stations, each base station sends that copied data to a serving radio network control device (S-RNC) directly or via a drift radio network control device (D-RNC), and the S-RNC selectively combines and outputs the received copied data; wherein a congestion monitoring unit monitors the congestion state of a line between the D-RNC and S-RNC, and when that line is congested, a D-RNC selectively combines the copied data that is inputted from the plurality of base stations and sends the result to that line, and when the line is not congested, the D-RNC sends the copied data that is inputted from the plurality of base stations to the line without performing selective combination.

It is intended to provide a Pb-free semiconductor ceramic composition capable of shifting its Curie temperature toward a positive direction and capable of enhancing its jump characteristic while minimizing the increase in the resistivity at room temperature. There is provided a semiconductor ceramic composition in which a part of Ba of BaTiO3 is substituted with Bi—Na, the semiconductor ceramic composition being obtained by sintering a mixed calcined powder containing a calcined BT powder containing a calcined powder of (BaR)TiO3 or a calcined powder of Ba(TiM)O3 (in which R and M each are a semiconductor dopant), and a calcined BNT powder containing a calcined powder of (BiNa)TiO3; in which BaCO3 and/or TiO2 is/are added to the calcined BT powder or the calcined BNT powder or to the mixed calcined powder.

It is intended to provide a semiconductor ceramic composition in which a part of Ba in BaTiO3 is substituted with Bi—Na, which is capable of restraining the evaporation of Bi in the calcination step, is capable of restraining the compositional deviation of Bi—Na thereby suppressing the formation of different phases, is capable of further reducing the resistivity at room temperature, and is capable of restraining the fluctuation of the Curie temperature; and to provide a production process of the same. When a calcined Ba(TiM)O3 powder (M is a semiconductor dopant) and a calcined (BiNa)TiO3 powder are separately prepared and the Ba(TiM)O3 powder is calcined at a relatively high temperature while the (BiNa)TiO3 powder is at a relatively low temperature, both at the most suitable temperatures for them, then the evaporation of Bi may be retarded and the compositional deviation of Bi—Na may be thereby suppressed to inhibit the formation of different phases; and when these calcined powders are mixed, formed and sintered, then a semiconductor ceramic composition which has a low resistivity at room temperature and is capable of restraining the fluctuation of the Curie temperature can be obtained.

The invention intends to provide, in BaTiO3 semiconductor porcelain composition, a semiconductor porcelain composition that, without using Pb, can shift the Curie temperature to a positive direction and can significantly reduce the resistivity at room temperature. According to the invention, when Ba is partially substituted by an A1 element (at least one kind of Na, K and Li) and an A2 element (Bi) and Ba is further substituted by a specific amount of a Q element, or when Ba is partially substituted by an A1 element (at least one kind of Na, K and Li) and an A2 element (Bi) and Ti is partially substituted by a specific amount of an M element, the optimal valence control can be applied and whereby the resistivity at room temperature can be significantly reduced. Accordingly, it is optimal for applications in a PTC thermistor, a PTC heater, a PTC switch, a temperature detector and the like, and particularly preferably in an automobile heater.

摘要:
Plasma processing of plural substrates is performed in a plasma processing apparatus, which is provided with a plasma processing chamber having an antenna electrode and a lower electrode for placing and retaining the plural substrates in turn within the plasma processing chamber, a gas feeder for feeding processing gas into the processing chamber, a vacuum pump for discharging gas from the processing chamber via a vacuum valve, and a solenoid coil for forming a magnetic field within the processing chamber. At least one of the plural substrates is placed on the lower electrode, and the processing gas is fed into the processing chamber. RF power is fed to the antenna electrode via a matching network to produce a plasma within the processing chamber in which a magnetic field has been formed by the solenoid coil. This placing of at least one substrate and this feeding of the processing gas are then repeated until the plasma processing of all of the plural substrates is completed. An end of seasoning is determined when a parameter including an internal pressure of the processing chamber has become stable to a steady value with plasma processing time.
