Abstract: Based on a ratio between Doppler frequencies calculated from a plurality of reception signals outputted by a receiver, a position detector calculates a relative position of a plurality of antennas in a mobile wireless apparatus to a stationary wireless apparatus. A train position detector calculates a position of a train from the calculated relative position, a placement position of the stationary wireless apparatus and placement positions in the train of the plurality of antennas.

Abstract: An elevator device includes an operation control unit (18), a storage unit (22), a transmission unit (23), a determination unit (25), and a recovery unit (26). When an inspection operation is interrupted by the operation control unit (18), the transmission unit (23) transmits inspection data stored in the storage unit (22) to a plurality of specific devices (20). The determination unit (25) determines whether or not recovery conditions are satisfied on the basis of a plurality of responses from the devices (20) to which the transmission unit (23) transmits the inspection data. For example, the recovery unit (26) restores a normal operation when the determination unit (25) determines that the recovery conditions are satisfied.

Abstract: A method for controlling an operation of an elevator system is discloses. The elevator system includes an elevator car moving within an elevator shaft and at least one elevator cable connected to the elevator car and the elevator shaft to carry electrical signals to the elevator car. The method determines a counter force on the elevator cable required to change a nominal shape of the elevator cable to an inverse shape of a current shape of the elevator cable caused by disturbance on the elevator system and applies the counter force to the elevator cable.

Abstract: A boss is provided around the periphery of a bushing that is penetrated by a shaft, which moves inside the bushing in the axial direction of the shaft. The boss retains the bushing and the shaft moving inside the bushing, and has a heat conductivity that is higher than that of the bushing. An air gap is provided between the bushing and the boss.

Abstract: A gas insulated bus is provided which comprises a metallic container whose axis is an axis line; a main circuit conductor housed in the metallic container; a metallic container to be connected with an end of the metallic container and whose axis is an axis line crossing the axis line; a main circuit conductor housed in the metallic container; an insulating spacer of a single-leg structure that supports and insulates a connection portion of the main circuit conductors; a metal-made shield attached to the insulating spacer and provided with an opening open in a direction of the axis line and an opening open in a direction of the axis line, the shield covering the connection portion, the shield being substantially in a barrel or spindle shape having an outside diameter exceeding that of the main circuit conductors.

Abstract: A method for a channel of a Code Division Multiple Access telecommunication system, the Code Division Multiple Access telecommunication system implementing a phase of communicating data conveyed by a plurality of transport channels, the Code Division Multiple Access telecommunication system comprising at least one sending entity and at least one receiving entity for communicating the data, the phase of communicating data comprising a plurality of rate matching steps, each of the plurality of rate matching steps executing a transformation of an input block of an initial size into an output block of a final size by puncturing or repeating at least one bit of the input block.

Abstract: A transmitting station includes: an error detecting code attachment block that attaches error detecting codes respectively to a plurality of data pieces; a transmitter block that transmits the plurality of data pieces with the error detecting codes attached thereto to a receiving station by using different radio frequencies, respectively; a receiver block that receives, from the receiving station, the results of error detections that the receiving station applies respectively to the plurality of data pieces on the basis of the error detecting codes attached respectively to the plurality of data pieces; and a transmission data managing block that controls retransmission of the data to the receiving station on the basis of the received results of the error detection.
