  • Patent number: 10875558
    Abstract: When there is a train entering a building of a rail yard, a ground apparatus stores vehicle-formation-set IDs of respective vehicle-formation-sets of the train in the entering order by a FILO method. Additionally, when there is the train leaving the building, the vehicle-formation-set IDs are sequentially read by the FILO method, an inquiry addressed to the vehicle-formation-set IDs is transmitted in the order of the reading to obtain the train information from the on-board apparatus of each of the vehicle-formation-sets forming the train. When the on-board apparatus does not respond to the inquiry, and obtaining of the train information fails, the ground apparatus performs a predetermined alarm output control.

  • Patent number: 8625252
    Abstract: An ion diffusing apparatus is disclosed which can maintain a stable ion supplying capability. In the ion diffusing apparatus, the ion generator is detachable for easy maintenance and can deliver the positive ions and negative ions to a remote position while uniformly generating positive ions and negative ions. The ion diffusing apparatus includes an ion generator housing which houses the generator so that a positive ion generating part and a negative ion generating part are provided separately in a direction crossing a flow direction of a stream from a fan, and an ion generating surface is exposed which conforms to a stream flow surface of a stream flow passage extended from the fan to a supply opening. The ion generator may also be a cartridge which has an ion generating surface shaped to conform to the stream flow surface of the stream flow passage.

  • Publication number: 20110133098
    Abstract: Disclosed is an ion diffusing apparatus that can realize easy replacement of an ion generator and can maintain a stable ion supplying capability. Also disclosed is an ion generating cartridge. In the ion diffusing apparatus, the ion generator is so configured that the generator is detachable for easy maintenance, and can deliver the positive ions and negative ions to a position remote from the apparatus in a room while uniformly generating positive ions and negative ions. An ion diffusing apparatus (1) includes an ion generator housing part. An ion generator (10) is housed in the ion generator housing part in such a posture that a positive ion generating part (13A) and a negative ion generating part (13B) are provided separately from each other in a direction crossing a flow direction of a stream from a fan (3), and an ion generating surface (11a) is exposed so as to conform to a stream flow surface of a stream flow passage extended from the fan (3) to a supply opening (4).

  • Patent number: 6092216
    Abstract: A disk controlling apparatus creates sense data indicating the contents of an error and writes it into an intermediate buffer provided within the disk controlling apparatus together with the record normally read when a key portion or a data portion constituting a record is not normally read. The disk controlling apparatus searches the intermediate buffer for desired record, reads and informs an error while taking the sense data into consideration for each record. The disk controlling apparatus stores a write address in a memory at the time of writing data, and when data are normally written the write address is eliminated from the memory, while holding the address when data are not normally written. At the time of reading data, if the address which agrees with the read address is stored in the memory, the disk controlling apparatus reports an error to a host apparatus.
