Abstract: A motorman's cab in a train is provided with a plurality of door operating switches that open and close the train doors on the station-platform side in a fully-automatic manner, in a semi-automatic manner, or in a manner that open and close doors in sections. A central device includes an information control unit that specifies a stopping station where a train stops next on the basis of train information; selects a recommended door operating switch at the stopping station from among the door operating switches on the basis of an estimated passenger-number value, which is the number of passengers at the stopping station, as a recommended door operating switch for the stopping station; and then it displays display information that prompts the train crew to operate the selected door operating switch on a display device in the control platform.

Abstract: A central device includes an information replacing unit. When the information replacing unit detects, on the basis of contact information acquired from an electric coupler provided in a coupled vehicle in a formation B having a train-information management device that manages vehicle information in accordance with the Ethernet® protocol, that a formation A that includes a train-information management device that manages vehicle information in accordance with the ARCNET protocol is coupled to the formation B, then the information replacing unit replaces vehicle information from the formation A with vehicle information in accordance with the Ethernet® protocol; outputs the replaced vehicle information to the formation B; replaces the vehicle information from the formation B with the vehicle information in accordance with the ARCNET protocol; and outputs the replaced vehicle information to the formation A.

Abstract: A train-information managing apparatus receives a series of control information attached to serial numbers, which are transmitted from a central apparatus, in order of the transmission and carries out control in the order, and even when the central apparatus is changed or the serial numbers are reset, prevents a blank period of control from occurring. Therefore, when a reception serial number n included in received data is a preferential serial number (n?M) and an old number nprev, which is a serial number included in data received and stored last time, is a cyclic serial number (nprev?M+1), the train-information managing apparatus stores the received data.

Abstract: A train information management apparatus includes a first system central device that generates first train control information for a car-mounted device in every predetermined period and a second system central device that generates second train control information starting from the time at which the time obtained by multiplying the predetermined period with 1/2 has elapsed from the time point when the first train control information is transmitted. The first system central device generates a first packet every time the first train control information is generated and alternately transmits a first packet to a first system trunk transmission line and a second system trunk transmission line. The second system central device generates and transmits a second packet almost in the same manner except that the second packet is transmitted to a trunk transmission line on the opposite side of the trunk transmission line to which the first packet was transmitted.

Abstract: After latest door opening-side information is received from an operational management server on a ground after a train starts an operation, train-information managing apparatuses output the door opening-side information to display control apparatuses as guidance data, the display control apparatuses create video data indicating an opening side of doors for all stops at least between a next stop and a terminal station of the train using the door opening-side information, and displays perform display using the video data.

Abstract: The train-information management device includes a position detection unit; a regenerating-condition detection unit that detects a regenerative-brake usage condition; a train-line-information holding unit that holds therein information on a section in which a train is more likely to use a brake; a residual-air-amount calculation unit that calculates the amount of residual air in an air tank; and a compressor control unit that controls a compressor. In a regeneration-preparation condition, if a train is running through a position where the distance between the position and a section in which a train is more likely to use a brake is equal to or less than a given value, if the train does not use a regenerative brake, and if the amount of residual air reaches 0%, the compressor control unit causes a compressor to start generating compressed air.

Abstract: The present invention includes a position detection unit; a regenerating-condition detection unit; a train-line information holding unit that holds therein information on a section in which a train is more likely to use a brake; an air-conditioning set-value holding unit that holds therein a temperature set value of an air conditioner; and a target-temperature control unit that decides a target temperature. In a regeneration-preparation condition in which a train is running through a position at which the distance between the position and a section in which a train is more likely to use a brake is equal to or less than a given value and in which the train does not use a regenerative brake, the target-temperature control unit decides a value, generated by adding a predetermined value to the temperature set value, as the target temperature.

Abstract: A reverse transcriptase containing flowery portion or its extract originated from elm in Ulmus hollandica is disclosed. The reverse transcriptase of this invention shows an activity remarkably higher than that of a known reverse transcriptase inhibitor derived from Ulmus davidiana var. japonica. Low toxicity of the reverse transcriptase inhibitor of this invention allows it being successfully applied to pharmaceuticals with a potent activity at a low dose, foods and beverages.
