摘要： An optical communication system has a master station (10) and a plurality of slave stations (20-1 to 20-n) connected thereto via an optical fiber network (1), which is provided with an optical splitter (30) and a relay unit (10000) which relays signals transmitted/received between the master station and the plurality of slave stations. The master station includes a first controller (1000) for performing ranging between the master station and the relay unit, and the relay unit includes a second controller (11000) for performing ranging between the relay unit and the plurality of slave stations. The master station determines, on the basis of the results of ranging performed by the first and second controllers as well as reports from the slave stations, timings for the slave stations to transmit signals to the master station, and receives signals multiplexed through the optical fiber network from the slave stations.

摘要： A charged particle beam (12a, 12b) is transmitted through a specimen (14) for producing an irregular pattern as a first image. Further, a magnetic field to be measured (16) is arranged in space where a charged particle beam is passed between the specimen and an image plane thereby to produce a second image having an irregular pattern as in the foregoing case. The first image and the second image are processed to produce the deflection angle of the charged particle beam due to the magnetic field. This deflection angle is extracted from the entire positions of a cross section of the space where measurement is desired, thereby constructing projection data of a magnetic field by a charged particle beam. Furthermore, the magnetic field to be measured is rotated and the above-mentioned processing is performed from each direction to construct projection data. The projection data thus obtained and the computer tomography technique are used to determine a magnetic field at each point in space.

摘要： When observing a magnetization image on a magnetic thin film by means of a scanning transmission electron microscope, the effect of a stray magnetic field is made smaller than that of a magnetization in order to produce a clear magnetic structure of the magnetization image. In order to reduce the effect of the stray magnetic field in comparison to that of the magnetization, the invention provides a scanning transmission electron microscope equipped with a specimen-holder driving means which can rotate the surface of a specimen 5 preferably by more than 90 degrees with an axis parallel to the optical path of an electron beam 1 taken as a center and incline the surface of the specimen 5 around a center axis 22 perpendicular to an axis 24 rotated earlier over the surface of the specimen 5 with respect to a magnetic-recording track direction and also perpendicular to the axis parallel to the optical path of the electron beam 1. The invention also provides a magnetic-recording image observing method and an image processing method.
