Abstract: In a magnetic coupling pump including a closed impeller, and a casing that houses the impeller in such a way that the impeller is rotatable around a rotation axis and movable in an axis direction in which the rotation axis extends, reduction in the rotational frequency of the impeller can be suppressed even if thrust balance collapses temporarily and the impeller and the casing come into contact with each other. A tapered surface (24) or (55) is formed in at least a portion of at least one of a surface (24) or (53) of the impeller (10) and a surface (66) or (86) of a pump casing (60) that faces each other in an axis direction (Da) so that the distance between both the faces varies gradually as it goes in a radial direction (Dr) perpendicular to the axis direction (Da).

Abstract: A target substance can be produced by culturing a bacterium having an ability to produce 2-ketoglutaric acid or a derivative thereof, and an ability to produce xylonic acid from xylose, which is imparted with xylonate dehydratase activity, 2-keto-3-deoxyxylonate dehydratase activity and 2-ketoglutaric semialdehyde dehydrogenase activity, or in which these activities are enhanced, in a medium containing xylose as a carbon source to produce and accumulate the target substance in the medium, and collecting the target substance from the medium.

Abstract: A magnetic-drive coupling pump configuration including an attachment/detachment mechanism allowing simple and reliable positioning and fixation is provided. Thrust-direction positioning and radial-direction positioning are achieved, respectively, by surface contact of a convex portion of a pump unit (10) inserted up to a predetermined position in a concave portion (31) of a drive motor unit (30), and contact between an outer circumferential surface of the convex portion (11) and an inner circumferential surface of the concave portion (31).

Abstract: A vehicle control device for a first railroad vehicle includes a case, a first wireless router device housed in the case, and an antenna device. The antenna device is installed on any of outer peripheral surfaces of the case. The first wireless router device transmits collected operation data of the vehicle control device via the antenna device and a first wireless communication network to a second wireless router device arranged in a second railroad vehicle so that a gateway router also arranged in the second railroad vehicle can transmit the collected operation data to an external server via a second wireless communication network.

Abstract: A drive unit of a magnet coupling pump, in which leakage of the magnetic flux to the outside and effect of the external magnetic field are suppressed, is provided. It includes: a driving magnet (219) positioned at an outside of the driven magnet (19) of the magnetic coupling pump (100) with respect to a rotation axis (A) of the magnetic coupling pump (100) to face the driven magnet (19) with a gap; a cup tube portion (221) made of a ferromagnetic material and in a tubular shape centered on the rotation axis (A); a case main body (231) including a cup (220) in which the driving magnet is fixed inside of the cup tube portion; a motor (210) rotating the cup around the rotation axis, and a tube portion (232), which is in a tubular shape and the cup is provided in the tube portion (232) with a gap.

Abstract: On a screen of a display unit, all NODEs in a ring network to which a connected node (NODE) belongs are minimized and displayed on a screen of a display unit, and a line connecting NODEs with each other is displayed between respective NODE icons. Display colors of the NODE icon and the line icon are changed depending on presence/absence of a failure. Further, a display color of each object displayed in each window varies in a plurality of stages in accordance with a degree of a failure.

Abstract: A graphics map of an area in which a system is set is displayed on a screen of a display unit, and minimized stations and line connecting between the stations are displayed on the map. Display colors of the station icon and the line icon are changed in accordance with presence/absence of a failure. When each station icon is clicked, a window showing a list of NODEs belonging to that station is opened, and a NODE having a failure and a NODE having no failure are also distinguished from each other by changing the display colors in this window.

Abstract: The present invention provides to an access management method and the communications apparatus capable of limiting an access from a monitor and control apparatus to a communications apparatus. In each of transmission apparatuses N1 to Nm, identification information of a monitor and control apparatus requesting an access is first obtained, and a uniquely determined level for each of monitor and control apparatuses WS1 to WSm is determined. A function of the monitor and control apparatuses requesting an access and its operation type are identified and, after that, it is determined on the basis of a predetermined table whether the access can be permitted or not.
