A storage control method comprising steps of; accepting a file that includes a plurality of pieces of text data and a piece of information indicating a correspondence between each of the plurality of pieces of text data and attributes of the piece of text data; classifying the plurality of pieces of text data into a plurality of groups in accordance with the plurality of attributes that are each associated with any one of the plurality of pieces of text data, based on the piece of information indicating the correspondence included in the accepted file; generating, for each of the plurality of groups, a file that stores one or a plurality of pieces of text data included in the group; and storing the generated file in a storage destination corresponding to the attributes of the one or plurality of pieces of text data included in the file.

Storage control program, apparatus, and method

A non-transitory computer-readable storage medium storing therein an extraction program that causes a computer to execute a process includes: referring to a storage that stores correspondence information associating extraction attributes which match respective attributes of each data element included in a plurality of data elements, from among extraction attributes included in verification rules, and verification rules which include the extraction attributes, and identifying, for each of the plurality of data elements and for each attribute, the verification rule including the extraction attributes matching each attribute; identifying, for each of the plurality of data elements, a common verification rule which is common in the verification rules corresponding to the attributes of each data element; and extracting, for each verification rule, data for which the verification rule has been identified as the common verification rule.

Extraction program, extraction device and extraction method

An extraction apparatus includes an input-data analysis unit that, when an extraction process is performed on input data containing a plurality of XBRL files using a combination of a plurality of extraction criteria, each of the extraction criteria directly specifying an element and an aspect of each of the plurality of XBRL files, calculates, from the input data, distribution information containing distribution of values of individual aspects of a plurality of elements that are individually provided by the plurality of XBRL files, and an application-sequence determining unit that determines an application sequence of the plurality of extraction criteria by referring to the calculated distribution information. Hence, the extraction apparatus can extract XBRL data pieces containing data items to be validated against a validation rule from the input data rapidly.

A railcar damping device includes: a tank storing a liquid; a first opening/closing valve provided in a first passage connecting a rod side chamber to a piston side chamber, which are defined by a piston, to be capable of opening and closing the first passage; a second opening/closing valve provided in a second passage connecting the piston side chamber to the tank to be capable of opening and closing the second passage; and a pump that is driven to rotate at a predetermined normal rotation speed in order to supply the liquid from the tank to the rod side chamber, wherein a rotation speed of the pump is reduced when a thrust command value is smaller than a normal lower limit value, which is a lower limit value of a thrust that can be generated by the actuator when the pump is rotated at the normal rotation speed.

Railcar damping device

A vibration damping device for railway vehicle includes an actuator and a damper circuit that causes the actuator to function as a damper. The actuator includes a cylinder coupled to a truck of a railway vehicle, a piston, a rod coupled to the piston and a body, a rod-side chamber and a piston-side chamber inside the cylinder, a first on-off valve for a first passage that communicates between a rod-side chamber and a piston-side chamber, a second on-off valve for a second passage that communicates between the piston-side chamber and a tank, and a pump that supplies a hydraulic fluid into the rod-side chamber. The hydraulic fluid has such kinematic viscosity-temperature characteristics that a kinematic viscosity of the hydraulic fluid ranges from 7 mm/s to 50 mm/s in a temperature range of from 20&#xb0; C. to 60&#xb0; C.

A vibration control device for railroad vehicle includes an actuator with a cylinder coupled to a truck of a railroad vehicle, a piston, a rod coupled to the piston and a vehicle body, a rod-side chamber and a piston-side chamber in the cylinder, a tank, a first on-off valve disposed at an intermediate position of a first passage communicating between the rod-side chamber and the piston-side chamber, a second on-off valve disposed at an intermediate position of a second passage communicating between the piston-side chamber and the tank, and a pump for supplying fluid to the rod-side chamber. A warm-up operation of the actuator is performed by opening the first and second on-off valves and driving the pump after the vibration control device is started and before a transition is made to a normal control mode for suppressing the vibration of the vehicle body.

An apparatus, which extracts and outputs a formula included in a target program that processes an extensible-business-reporting-language (XBRL) document, includes: a variable extracting unit that extracts a variable included in the formula; an element identifying unit that identifies an XBRL element corresponding to the variable extracted, based on the XBRL document; and a label identifying unit that identifies a label corresponding to the XBRL element identified, based on the XBRL document.

Method and apparatus for converting formula included in a computer program

A data entry restriction program capable of rejecting invalid structured documents out of structured documents of a general-purpose format with great flexibility. When a structured document is entered, a data entry restriction apparatus compares the structure of the structured document with flexibility requirements (step S). When the structured document does not meet the flexibility requirements, the data entry restriction apparatus records error information in association with the sending client of the document (step S). After the error information associated with the client exceeds prescribed limits, the data entry restriction apparatus rejects structured documents from the client (step S). Structured documents which meet the flexibility requirements and the data entry restriction apparatus has accepted are entered into a data processing apparatus and analyzed (step S).

Program and method for restricting data entry

By mounting a semiconductor carrier tray in an accommodating portion of a housing of a burn-in board and then closing a lid member, a large number of semiconductors can be placed on the burn-in board. By putting the burn-in board in this state into a burn-in tester, the plurality of semiconductors can be collectively tested. Accordingly, the semiconductors and sockets for holding the semiconductors need not be provided in the one-to-one relation, whereby a larger number of semiconductors can be tested at once.
