  • Patent number: 10725984
    Abstract: Provided is a time series data device with which, when a process is changed, results of both a new and an old process are not outputted to the outside being mixed, and the results of the old process before and after the process is changed can be outputted to the outside. The device is equipped with: a first processing unit that executes a first process and outputs first results data; a second processing unit that executes a second process and outputs second results data; and a control unit that, when an instruction to change a process is received, determines whether the first process can be stopped, and generates first and second results data sets by appending identification information corresponding to process contents to the respective first and second results data.

  • Patent number: 9266543
    Abstract: A train protection device, which decides a position of an own train on track by using GPS satellites, includes: a GPS reception unit; a tachogenerator unit; a track-information storage unit; and a position decision unit. The position decision unit decides the position of the own train based on the GPS signal, the reception state value, the running distance from the reference position, the current speed, and the information of a track on which the own train runs. When the reception state value is equal to or larger than a threshold, the position decision unit decides a position as a current train position by adding, with respect to a forward direction of the track on which the own train runs, a correction value.

  • Patent number: 9075669
    Abstract: Provided is a time series data processing device with which it is possible to change to a new process during the execution of an old process, and to control the selection and the output sequence of output data when processes are switched. A first processing unit executes a first process and generates first results data, and a second processing unit executes a second process and generates second results data. When an instruction to change processes is received from the outside, the first process in the first processing unit is stopped, and output of the first results data is prohibited. Then, the process in the first processing unit is changed from the first process to a third process and is started, and output of third results data is enabled.

  • Publication number: 20140256960
    Abstract: A transformant is prepared to insert at least a gene expression cassette comprising a gene involved in the synthesis of 2-deoxy-scyllo-inosose into E. coli as host cells. A 2-deoxy-scyllo-inosose is synthesized from D-glucose, oligosaccharide, polysaccharide, starch and rice bran, using the transformant. A culture solution containing the 2-deoxy-scyllo-inosose is treated with a mixed bed or double bed type column comprising a hydrogen form of strong acidic cation exchange resin and an organic ion form of basic anion exchange resin. The 2-deoxy-scyllo-inosose as purified is reacted with trimethoxymethane to convert into 2-deoxy-scyllo-inosose dimethylketal, and the dimethylketal is crystallized and purified. Then, DOI is highly purified through hydrolyzing the dimethylketal in the presence of acid.

  • Patent number: 8670883
    Abstract: To stop a train at a desired target stop position without outputting excessive brake by outputting an appropriate braking instruction in accordance with a running condition of the train. An on-train computing device causes an acceleration estimating unit to determine the presence/absence of a current acceleration of a train and to estimate the current acceleration based on train-car information obtained from a train-car performance manager unit, and causes a profile calculating unit to generate a braking instruction profile based on a presumption that the train is running at the current acceleration when the train is in an accelerating condition, and to generate the braking instruction profile based on a presumption that there is no acceleration applied to a train car of the train by a propulsion control of the train car itself when the train is in a coasting condition.

  • Patent number: 8638665
    Abstract: A router includes: a flit arrival time management section that records flit arrival time which is the time at which the packet is received for the first time, transmission interval of the packet which are acquired from a control packet transmitted prior to the first transmission of a packet and input and output channels of the control packet and requires a crossbar section for an output channel from which the packet is supposed to be output before the flit arrival time; a switch assignment section that performs arbitration on the output channel request and performs input/output connection relationship setting processing; and a switch assignment verification section that verifies whether a result of the input/output connection relationship setting processing coincides with the actual routing of the packet. The cross bar section performs switching of the arriving packet using a result of the input/output connection relationship processing.
