A method is disclosed for measuring stress distribution generated on a structural object including two support parts and a beam part provided between the support parts. The method includes: generating first data by sensing, through a first sensing unit, of a moving object or an identification display object attached to the structural object; calculating, based on the first data, a movement duration in which the moving object moves between the support parts; generating, as second data, thermal data by sensing of a surface of the beam part through a second sensing unit; calculating a temperature change amount based on a second data group corresponding to the movement duration; and calculating a stress change amount based on the temperature change amount to calculate stress distribution based on the stress change amount.

Stress distribution measurement method and stress distribution measurement system

A stress distribution measurement method is a method of measuring stress distribution generated on a structural object including two support parts and a beam part provided between the support parts. The method includes: generating first image data by performing, through a first image capturing unit, image capturing of a moving object or an identification display object attached to the structural object from the moving object; calculating, based on the first image data, a movement duration in which the moving object moves between the support parts; generating, as second image data, thermal image data by performing image capturing of the surface of the beam part through a second image capturing unit; calculating a temperature change amount based on a second image data group corresponding to the movement duration; and calculating a stress change amount based on the temperature change amount to calculate stress distribution based on the stress change amount.

A magazine management device stores a plurality of magazines in which a plurality of optical discs is housed. The magazine management device includes a case that supports the plurality of magazines, a plurality of partitions that divides the case so as to form a plurality of regions in which the magazines can be stored one by one, an antenna that transmits a radio wave for asking a radio identifier provided to the magazine for a response and receives a radio wave of the response transmitted from the radio identifier, and an arithmetic processor that receives information obtained from the radio wave of the response received by the antenna.

Magazine management device, disc device, and magazine management system

Magazine management device in which one or more antennas disposed in one antenna base communicate with two or more radio identifiers corresponding to two or more magazine regions

This optical read/write apparatus has first and second optical headsand includes location control sectionswhich make the relative arrangement of the first and second optical headsvariable according to either the environmental temperature or from one medium to another. The first optical headperforms a write operation to record a mark on an optical storage medium, and the second optical headreads the information that has been written by scanning the recorded mark. The apparatus further includes a nonvolatile memory which saves the relative arrangement of the first and second optical headsandeither on an environmental temperature basis or on a medium by medium basis.

Optical read/write apparatus

An optical read/write apparatus according to an embodiment includes: an optical head unit () which focuses a write light beam and a read light beam onto an optical storage medium () and which generates a signal based on the light beam that has been reflected from the optical storage medium; and a control section () which controls the optical head unit () so that the optical head unit records a mark on the optical storage medium by irradiating the optical storage medium with the write light beam and reads the recorded mark on the optical storage medium with the read light beam. After having started to record the mark on the optical storage medium by irradiating the optical storage medium with the write light beam and before forming the recorded mark completely, the optical head unit () reads the recorded mark on the optical storage medium with the read light beam.
