Abstract: In an ATM exchange, a cell transmission control section transmits an ATM cell to a transmission path of an ATM network. A traffic monitor monitors traffic of the cell transmissions. A statistical process section performs a temporal statistical process on the result of the traffic monitoring using a clock and a memory. A CAC produces an instruction for traffic control over a transmission terminal based on the result of the statistical process. A UPC controls traffic of a transmission path from the transmission terminal in accordance with the instruction.

Abstract: A mobile communication system, in which a technology being capable of simply executing soft handover with low cost is used, is provided. At the mobile communication system in which plural base stations and plural mobile stations are provided, a mobile station provides a first measuring means for measuring first phase difference between a signal that the mobile station is transmitting to the base station and a signal that was transmitted from the base station to the mobile station, and a first transmitting means for transmitting the first phase difference measured at the first measuring means to another base station to which the handover is executed when the mobile station requests the handover.

Abstract: A mobile satellite communication system includes a base station apparatus, and a plurality of mobile terminals coupled to the base station apparatus through an artificial satellite. Also, there are a forward link from the base station apparatus to the plurality of mobile terminals, and a return link from the plurality of mobile terminals to the base station apparatus. The base station apparatus transmits an access control signal to one of the plurality of mobile terminals through the forward link. The mobile terminal determines whether a correct reception indication data or an incorrect reception indication data is contained in the access control signal, and performs retransmission of the short burst transmission when it is determined that the incorrect reception indication data is contained in the access control signal.

Abstract: A thrust bearing supporting device for an electric rotary machine comprises a plurality of supporting members fixed to a base plate within a bearing vessel for supporting a thrust bearing of said rotary machine, each of said supporting members consisting of a pair of supporting pieces, each of said supporting pieces having a recessed portion formed therein, wherein each of said supporting members is formed by placing one supporting piece on the other in face-to-face relationship thereby forming a space within each of said supporting members.

Abstract: For a vertical shaft electric rotary machine comprising a pair of upper and lower vertical shafts extending from a rotor and rotatably supported by a bearing within an upper oil tank and a bearing unit within a lower oil tank respectively, a disclosed bearing lubricating system comprises an amount of a lubricating oil charged into each of the oil tanks, centrifugal pump means per se known and disposed around the bearing unit to pump the lubricating oil to an external oil cooler, an annular tub disposed below the centrifugal pump means to receive the lubricating oil from the oil cooler, a supply pipe with a flow rate control valve connected between the oil cooler and the upper oil tank and a return pipe connected between the upper and lower oil tanks.
