Abstract: A metal member according to this invention is composed of polycrystals of a metal made of ruthenium or an alloy containing ruthenium at a maximum ratio. The aspect ratio of a crystal grain of the polycrystalline metal member is 1.5 or more. A plurality of crystal grains forming the metal member are arranged with their major axes being pointed in the same direction, and the number of crystal grains in a section in the major axis direction of the crystal grains is 120 or less per 1 mm2.

Abstract: Communication becomes impossible for many mobile stations when a communication failure occurs in a fixed station while the mobile stations are operating in an infrastructure mode. Provided is a communication system that includes a plurality of mobile stations and at least one of a base station and a wireless LAN access point, wherein the plurality of mobile stations establish communication with each other and form an ad hoc network that realizes a mesh network topology, and at least one mobile station among the plurality of mobile stations establishes communication with at least one of the base station and the wireless LAN access point, and connects another mobile station among the plurality of mobile stations to the at least one of the base station and the wireless LAN access point using a tethering function.

Abstract: A monitor request instruction issuing-side shared memory (14) into which a list of devices to be monitored based on monitoring requests is provided between a monitoring application executing-section (11) and a monitor request instruction issuing unit (13). A monitor data obtaining-side shared memory (16) into which monitor data obtained by a monitor data obtaining unit (15) is written is provided between the monitoring application executing-section (11) and the monitor data obtaining unit (15). Thus, the monitor request instruction issuing unit (13), the monitor data obtaining unit (15), and the monitoring application executing-section (11) can operate mutually asynchronously. Further, a data flow is made in one direction, and an exclusive control relating to share memories can be minimized.

Abstract: A sleeve for splicing together reinforcing bars disposed in an opposing, end-to-end relationship comprising a tubular shell member provided with opposing end walls, a grout port provided in the tubular shell for adding grout to the interior of the tubular shell, apertures provided in the end walls for receiving the reinforcing bars from opposite ends thereof, a plurality of supporting projections integrally formed with the tubular shell and extending from one side of the tubular shell, fixing means adapted to be inserted into the tubular shell on longitudinally opposite sides from the supporting projections and intermediate the supporting projections for fastening the reinforcing bar to the supporting projections, the supporting projections being formed, in cross section, with a recess for receiving the reinforcing bar coaxial to the tubular shell.

Abstract: A transformer with laminated sheet cores consists of a coil bobbin having a core hole, and a plurality of laminated sheet cores, each having a middle leg inserted into the core hole and a fixing member such as a cover fixed to the coil bobbin, receiving the ends of the sheet cores so as to prevent the sheet cores from being removed from the cover. The laminated sheet cores are fixed to the core bobbin without being pressed in the direction of their total thickness and without lowering the core characteristic. The transformer has a smaller number of the cores and can be manufactured at smaller processes.

Abstract: A programming device for a programmable controller comprising a unit specification information table in which specifications of a functional unit are set, a unit configuration table in which combinations of functional units are set, and a program preparing means for assisting input of a program for a programmable controller according to various types of information in said unit specification information table and the unit configuration information table.

Abstract: A mortar grout splice sleeve (1) for reinforcing bars has a tubular metal shell (2) formed in both end portions (3) thereof with opposite openings (4) through which reinforcing bars (15) are inserted, and an annular seal (10) mounted in each of the end portions (3). The shell is formed in an tubular portion of thereof with a grout port (5) through which mortar (16) is injected into the shell. The seal (10) has a central bore (17) to be slidably fitted on the reinforcing bar (15). The seal (10) has an external circumference (11) tapered toward the shell (2) for fitting engagement with an inward tapered internal circumference (9) formed in the end portion (3) of the shell (2).
