Abstract: In an IP packet communication apparatus, an operation and maintenance function capable of monitoring a transmission path is provided to a layer used to process a packet, which corresponds to an upper layer of an optical network. As one method for applying the operation and maintenance function to the packet layer, in the case of IP over PPP over WDM, an operation/maintenance frame is defined to a PPP frame so as to realize the operation/maintenance function of a PPP connection. In the case that a plurality of connections are multiplexed on the same transmission path, a maintenance frame is conducted in order to operate/manage these connections by being grouped, so that a fault occurring in the optical network is monitored. As another method for applying the operation and maintenance function to the packet layer, an operation/maintenance frame is defined to an IP packet so as to realize an operation and maintenance function of an IP flow.

Abstract: In a non-leaded type semiconductor device, a tab, tab suspension leads, and other leads are exposed to one surface of a seal member. A semiconductor element is positioned within the seal member and fixed to a surface of the tab with an adhesive. The tab is formed larger than the semiconductor element so that outer peripheral edges of the tab are positioned outside outer peripheral edges of the semiconductor element. A groove is formed in the tab surface portion positioned between the area to which the semiconductor element is fixed and wire connection areas to which the wires are connected, the groove being formed so as to surround the semiconductor element fixing area, thereby preventing peeling-off between the tab to which the semiconductor element is fixed and the resin which constitutes the package.

Abstract: Data of a plurality of master tables can be replicated in one replica table. A job to access a plurality of tables can be executed by accessing one replica table, and hence the job execution time is minimized. A correspondence is established between data using, as a key, particular data in the data of a plurality of master tables. The data field for the key is defined by the replication definition. Timing of replication for the replica table is also defined in the program to execute replication. The replication program generates, at execution thereof, the control table according to the definition and manages the operation states of a plurality of master tables and the replication state of the replica table to thereby conduct replication for the replica table at the defined timing.

Abstract: Below 50-nm-diameter extremely narrow electrically-conductive fiber is used instead of the electron beam biprism used in the conventional interference electron microscope method. A phenomenon is utilized where a focus-shifted shadow of this fiber is shifted from a straight line by a distance which is proportional to a differentiation of phase change amount of an electron beam due to a sample with respect to a direction perpendicular to the fiber. The phase change amount is quantified by calibrating this shift amount through its comparison with a shift amount caused by another sample in terms of which the corresponding phase change amount has been quantitatively evaluated in advance. The differentiation amount of the quantified phase change in the electron beam due to the sample is visualized, or eventually, is integrated thereby being transformed into absolute phase change amount to be visualized.

The second file system is not proprietary, but rather is designed around a publicly known format. Access to the second file system does not require obtaining permission from the vendor of the first file system; e.g., licensing, payment of royalties, and so on.

Abstract: Four sensor units (SUA1 to SUA4) are disposed symmetrically about a point, on both top and bottom and left and right centering around one point of a support (15e). Furthermore, four sensor units (SUA1 to SUA4) are designed so that all the components are fully in tuning-fork structure. Drive frames (5, 5) of the sensor units (SUA1, SUA2) disposed adjacent to each other in a first direction (Y) are vibrated in mutually inverted phases, and drive frames of the other sensor units (SUA3, SUA4) disposed adjacent to each other in a second direction (X) are vibrated in mutually inverted phases as well. Moreover, the drive frames of the sensor units (SUA1, SUA2) and the drive frames of the other sensor units (SUA3, SUA4) are operated in synchronization in the state in which phases are shifted by 90 degrees. Whereby, it is possible to reduce or prevent vibration coupling in the driving direction and in the detection direction, and the leakage (loss) of excitation energy and Coriolis force.

Abstract: An excavation support database 40 includes a display table 47 and a display specifics table 48, which serve as storage means dedicated for display. The state of a working region per mesh is stored in the display table 47, and a discriminative display method (display color) is stored in the display specifics table 48 corresponding to the state per mesh. Reference is made to the display specifics table 48 on the basis of the state (height) per mesh, which is stored in the display table 47, to read the corresponding display color from the display specifics table 48, thereby displaying the state of the working region in a color-coded manner. Operation support and management realized with this system can easily be employed in different types of working machines in common and can inexpensively be performed with ease.
