Abstract: A recording apparatus includes a conveyance unit that conveys a recording medium in a first direction toward a recording head for ejecting a liquid, a tank including a containing chamber containing the liquid to be supplied to the recording head, and an injection port through which the liquid is injected into the containing chamber, the tank being disposed downstream of the conveyance unit in the first direction, a rotatable lever that holds a tank cap for closing the injection port, and a cover that rotates about a rotation shaft between an open position for exposing the lever and a closed position for covering the lever, the rotation shaft being disposed upstream of the conveyance unit in the first direction. The cover includes a sliding portion that is provided on a surface facing the lever and comes into contact with the lever while the cover is rotating toward the closed position.

Abstract: A recording apparatus includes a tank including a chamber configured to store liquid to be supplied to a recording head that ejects the liquid and a filling port from which the liquid is injected into the chamber, and an injection auxiliary member configured to assist injecting of the liquid into the chamber from the filling port, the injection auxiliary member including a first and a second flow channels each defined by a first or a second upper end portion that opens toward outside of the tank and a first or a second lower end portion that opens toward inside of the tank, wherein the second flow channel has an expansion portion arranged in a middle portion between the second upper end portion and the second lower end portion and configured to form a step to expand a cross-sectional area.

Abstract: Spectrum data of white neutrons having different spectrum shapes, and SEE counts obtained by a white neutron method using this multiple spectrum data, are stored. A computing section reads out the spectrum data, divides the data into energy groups, and calculates and stores a total flux of each energy group. Furthermore, the computing section reads out the SEE counts with respect to each of the spectrum data and the total flux of each energy group, substitutes the SEE counts and the total flux into a simultaneous equation, and calculates the SEE cross section for each of the energy groups. Subsequently, the computing section calculates parameters which determine a formula of the approximate function of the SEE cross section as a function of energy, so that computed values of error counts obtained by integration of multiple spectra and the approximate function sufficiently match the actual measured values thereof.

Abstract: When resistivity against errors caused by cosmic ray neutrons in a semiconductor device is evaluated, the storage in the evaluation apparatus stores multiple spectrum data of white neutrons having different spectrum shapes, and multiple SEE counts obtained by the white neutron method using this multiple spectrum data. A computing section performs processing, with respect to each spectrum data, to read out the spectrum data from the storage, divide the data into multiple energy groups, calculates and stores a total flux of each energy group.
