Abstract: A thermally conductive pipe includes a pipe of which both end portions are closed, a working liquid that is sealed inside the pipe and vaporizes and liquefies, and a liquid transfer unit that exists along a longitudinal direction inside the pipe and transfers the liquefied working liquid at least in the longitudinal direction, in which the liquid transfer unit has, in a case of being viewed in a cross section of the pipe, which is orthogonal to the longitudinal direction, a first liquid transfer unit that is in contact with at least a partial range of an inner wall surface of the pipe and a second liquid transfer unit that is not in contact with the inner wall surface of the pipe and the first liquid transfer unit.

Abstract: A heat pipe includes a tubular member that is a hollow member in which liquid is encapsulated and of which an inner surface is subjected to an oxidation treatment in advance and a movement section that moves the liquid encapsulated and liquefied in the tubular member along a longitudinal direction of the tubular member by means of a capillary phenomenon and of which a surface is subjected to an oxidation treatment in advance.

Abstract: A fixing device includes a belt member that cyclically moves, a pressing unit that comes into contact with the belt member and presses a recording medium moving between the belt member and the pressing unit, and a heat source that includes a base material, a resistance heating element disposed on a surface of the base material along a longitudinal direction of the base material, and an insulator covering the resistance heating element and that comes into contact with the pressing unit via the belt member to heat an inner surface of the belt member, in which the insulator is formed to cover a corner portion of the base material in a direction of movement of the belt member.

Abstract: A sandwich structure does not permit the permeation of water and a sandwich structure repairing method is capable of easily repairing the sandwich structure. A sandwich structure (1) includes a core (4) formed of a closed-cell foam plastic material, and surface plates (2, 3) formed of a fiber-reinforced composite material containing hydrophobic inorganic fibers as reinforcing fibers and bonded to the opposite surfaces of the core (4). Water is unable to permeate the sandwich structure.

Abstract: A mobile communication system having a small base station provides radio communications between the small base station and a mobile station. The small base station is connected with a central station via an optical transmission line. The central station includes a modulation section which modulates a time-division multiple signal, an electric/optic converter section which converts an output signal of the modulation section to an optical signal, and sends the optical signal to the optical transmission line. The central station further includes an optic/electric converter section which receives an optical signal from the small base station via the optical transmission line, and converts a received optical signal to an electrical signal, and a demodulation section which demodulates an output signal from the optic/electric converter section.

Abstract: An operator support system comprises an operation guidance generating unit 14 for displaying operation procedures to an operator on the basis of plant monitoring data, and a running operation evaluation processing unit 23 for comparing control object equipment and operation contents of a guidance table generated by the operation guidance generating unit 14 with operation contents selected by the operator and output through an operation selecting unit 22, and for evaluating that the operation contents are correct by coincidence thereof, to prevent an operator's operation error. Accordingly, the operator support system which is capable of evaluating whether or not the operation contents performed by an operator is adequate, and, if an inadequate running operation is performed, of informing the operator of an error without outputting that control output to the controlled plant.
