摘要： In a known wavelength multiplexer, optical signals to pass are passed with their wavelengths held identical. Therefore, unless an unused wavelength common to all zones exists in case of setting an optical channel, the channel cannot be set. According to the present invention, a drop/add type wavelength multiplexer includes a wavelength converting section (50 in FIG. 5) which converts the wavelengths of optical signals to pass from the input side of the multiplexer to the output side thereof. In a network employing the wavelength multiplexers at individual nodes, a new optical channel can be easily set by utilizing wavelengths not used at the nodes.

摘要： Communication time period measuring frames are simultaneously sent from an OAM adaptive device on a transmission side, to both a working path and a protection path. In an OAM adaptive device on a reception side, reception times of the frames having arrived from both the paths are checked so as to measure a time period difference between both the paths. The time period difference is fed back to a logic distance adjustment function of each PON section to determine required communication time periods of the PON sections respectively included in a working system and a protection system. Communication time periods of the working system and the protection system in a packet communication network are arbitrated in order to decrease a packet loss at line switching in a packet relaying network.

摘要： An apparatus for measuring an electromagnetic field distribution using a focused electron beam can measure the electromagnetic field distribution in a specimen with high resolution and high reliability. A focused electron beam radiation system irradiates a specimen with a focused electron beam. A specimen tilt mechanism tilts a specimen by 180.degree. about a tilt axis that is perpendicular to the optical axis of the focused electron beam. An electron beam position detector measures the direction and quantity of the deflection given to the focused electron beam when it is transmitted through the specimen. Further, a processing system calculates the direction and the intensity of an electric field, and the direction and the intensity of a magnetic field separately at a point on the specimen through which the focused electron beam is transmitted, from the data on the direction and the quantity of the deflection of the focused electron beam measured by the electron beam position detector before and after the turnover of the specimen by the specimen tilt mechanism. Thus, an electric field and a magnetic field in a specimen can be separately observed independently of each other.

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. To relatively reduce the effect of the stray magnetic field in comparison to that of the magnetization, the scanning transmission electron microscope is equipped with a specimen-holder driving means which can rotate the surface of a specimen 5 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. In the actual observation, however, a limit is put on the angle of rotation by which the surface of the specimen 5 is rotated with respect to the recording track direction.

摘要： Switching process at the occurrence of a path trouble is performed more quickly to reduce the number of packet discards during a traffic transition from a currently used system path to a standby system path within a section to be protected. An OLT (210-W) refers to the DBA information of a PON section and, if receiving no CCM frame at a timing at which the same should be received, then determines that some trouble has occurred on the path (S801) and transmits, to an OAM-compliant NE (200-Z), an application-for-switching frame (1501) to notify the OAM-compliant NE (200-Z) of the abnormal condition. The OAM-compliant NE (200-Z) monitors the occurrence of the trouble within the PON section nearly in real time, starts a switching process (S802) and generates and transmits a standby-system delivery request (321) (S302, S803). An OAM-compliant NE (200-A) switches the communication path to the standby-system passing through an OLT (210-P).
