Abstract: A method for producing an arm structure in which the arm structure is produced by: forming an arm precursor member having an external shape of the arm structure by, in a state in which a die is closed with a metal pipe member being disposed in a cavity thereof, pressurizing the pipe member with liquid supplied to an inside thereof to cause an external surface of the thus expanded pipe member to be pressed against an inner surface of the cavity; and forming a flange portion to be attached to a driven body by machining at least an end of the formed arm precursor member.

Abstract: An apparatus that includes a first conductive pattern positioned at a first wiring layer and extending in a first direction, a second conductive pattern positioned at a second wiring layer located above the first wiring layer and extending in a second direction crossing the first direction, and a contact plug connecting the first conductive pattern with the second conductive pattern. The contact plug includes a lower conductive section contacting the first conductive pattern and an upper conductive section contacting the second conductive pattern. A maximum width of the upper conductive section in the first direction is smaller than a maximum width of the lower conductive section in the first direction.

Abstract: A water electrolysis system including: a water electrolysis cell; a water supply device that supplies water to an oxygen electrode of the water electrolysis cell; a water supply channel that connects the water electrolysis cell and the water supply device and through which the water supplied from the water supply device to the oxygen electrode flows; a gas-liquid separator that separates the water and a gaseous component discharged from the oxygen electrode; a water discharge channel that connects the water electrolysis cell and the gas-liquid separator and through which the water and a gaseous component discharged from the oxygen electrode flow; and a recombiner disposed between the water electrolysis cell and the gas-liquid separator in the water discharge channel. The recombiner includes a recombination catalyst that reacts hydrogen and oxygen, and the water electrolysis cell and the recombiner are electrically insulated from each other.

Abstract: Provided is a method for producing an arm-like structure in which the arm-like structure is produced by: forming an arm precursor member having an external shape of the arm-like structure by, in a state in which a die is closed with a metal pipe member being disposed in a cavity thereof, pressurizing the pipe member with liquid supplied to an inside thereof to cause an external surface of the thus expanded pipe member to be pressed against an inner surface of the cavity; and forming a flange portion to be attached to a driven body by machining at least an end of the formed arm precursor member.

Abstract: In a state of mapping sensors having been advanced into a carrier by a sensor advance/withdraw mover, a sensor lifting and lowering device moves the mapping sensors up and down. With this movement, the mapping sensors detect presence or absence of substrates in a horizontal direction crossing a fore-and-aft direction in which the substrates are moved into and out of the carrier, and a height sensor detects heights of the mapping sensors. Consequently, substrate heights are detected in two different locations in the fore-and-aft direction. Based on the substrate heights, a substrate condition acquiring unit acquires a tilt of each substrate relative to the horizontal in the fore-and-aft direction. The tilt of each substrate inside the carrier is acquired in advance, thereby to be able to prevent substrate damage due to contact between a hand of a substrate transport mechanism and the substrates.

Abstract: A cellulose pulp slurry is delignified in an apparatus comprising a vertical cylindrical barrel chamber, a cone-shaped bottom chamber connected to the barrel chamber and having a circular inlet formed in a lower end portion thereof, and a cone-shaped top chamber connected to the barrel chamber and having a circular outlet formed in a top end portion thereof, in which apparatus the cone-shaped top and bottom chambers converge at a convergence angle of 60 degrees or less respectively, by feeding a cellulose pulp slurry containing an alkali and oxygen and having a pulp consistency of 8 to 15% into the apparatus through the circular inlet of the bottom chamber at 70.degree. C. to 140.degree. C., and discharging the pulp slurry through the circular outlet of the top chamber, while controlling the flow speed of the pulp slurry in the barrel chamber to a level of 0.4 m/min or more.

Abstract: A rotor shaft suitable for use as the rotor shaft of a steam turbine. The rotor shaft has a rotor shaft portion made of a Cr alloy steel having martensite structure and containing 8 to 13% Cr. The rotor shaft body is provided with at least one journal portion at which the rotor shaft is rotatably supported by a bearing. The rotor shaft further has a sleeve fitted around each journal portion. The sleeve is divided in the circumferential direction into a plurality of segments which are assembled together by welding or fitting into the sleeve having a circular cross-section. Due to the provision of the sleeve around the journal portion, the rotor shaft made of Cr alloy steel can have improved bearing properties.
