    摘要: An enclosure of an electronic computing apparatus allows two electronic computing modules, each having a built-in fan, to be mounted in a perpendicular direction, when the two electronic computing modules are inserted, a shutter is at an intermediate position due to an elastic force of pushing a spring cover in a front surface direction, from push rods corresponding to the two electronic computing modules, and when one of the electronic computing modules is removed, the elastic force of pushing the cover from the push rod on the removal is lost, and the shutter moves, around a rotating mechanism, to a side of a housing space on the removal side and shuts off a flow path in the housing space.

    摘要: A radionuclide production system is a system for producing a radionuclide by irradiating a liquid containing a raw material nuclide with bremsstrahlung radiation, the radionuclide production system including: a circulation path configured to allow a liquid containing a raw material nuclide to circulate; and a radiation generation unit configured to generate bremsstrahlung radiation to irradiate the liquid. A metal member containing a pure metal of a platinum group or an alloy of the platinum group is provided at an upper portion in the circulation path. In a radionuclide production method, the raw material nuclide contained in the liquid is transformed to the radionuclide by irradiating the liquid with the bremsstrahlung radiation while circulating the liquid containing the raw material nuclide in the circulation path, and oxygen and hydrogen generated due to radiolysis of the liquid are removed by a recombination reaction with a metal member formed of the pure metal.

    摘要: There is provided an application screen display program implementation method for executing application software to display a screen using an information processing apparatus. Each record of a master table for controlling the display of each display element for display elements configuring a screen and transaction data input and output from the display element has a field for holding an index of an array, and association with an index of an array in a source code of an execution program is performed. Therefore, in application development, the required man-hours with respect to the change of the display screen are reduced.

    摘要: An administrative terminal receives designation of generation target data and of a generation destination storage device and identifies data similar to the target data. The terminal calculates a first predicted time expected for transmitting the target data from a storage device holding the target data to the generation destination storage device, and a second predicted time expected to be required for a second transmission process of transmitting the similar data from an object storage service to the generation destination storage device and of transmitting difference data between the target data and the similar data from the storage device holding the target data to the generation destination storage device. If the second predicted time is shorter than the first predicted time, the administrative terminal performs the second transmission process to transmit the similar data and the difference data to the generation destination storage device to generate the generation target data therein.

    摘要: A superconducting wire connector includes superconducting wires and a sintered body containing MgB2. The superconducting wires are connected by the sintered body. At least one of the superconducting wires includes a superconducting core having a first outer surface. The sintered body is in contact with the first outer surface. A method of connecting superconducting wires by a sintered body containing MgB2 includes exposing a superconducting core of at least one of the superconducting wires by removing a portion, positioned in the middle in a longitudinal direction of the at least one of the superconducting wires, of a metal sheath disposed around the superconducting core, disposing the at least one of the superconducting wires through a container, filling the container with a raw material of MgB2, and forming the sintered body being in contact with an outer surface of the superconducting core by sintering the raw material filled in the container.
