摘要： A screw extruder for extruding a kneaded material, includes: a screw; and a casing housing the screw and having a material supply port on an upstream side. The screw has a shaft portion and a helical flight portion provided on an outer peripheral surface of the shaft portion. Regarding a clearance between a top portion of the flight portion and an inner wall surface of the casing, the clearance at a downstream side end of the flight portion is larger than the clearance at a downstream side end of the supply port. No area where the clearance decreases from the upstream side toward the downstream side is present between the downstream side end of the supply port and the downstream side end of the flight portion.

摘要： Provided is a multi-jointed welding robot that includes: a rotating part that is rotatably provided on a base that is fixed to an installation surface; and a multi-jointed arm that is coupled to the rotating part via a first driving shaft and has a plurality of arm parts. An opening is formed in the rotating part through which a routing member, which is routed inside the rotating part, is guided from part of the rotating part toward the side opposite the installation surface. A guide member guides the routing member, which has one end fixed to the opening and which is guided through the opening, toward the installation surface from the other end of the routing member while bending the routing member.

摘要： An upper turning body mounted on a lower body for a crane includes a turning frame mounted on the lower body to turn freely, and a boom provided to the turning frame to be raised and lowered freely. The turning frame includes a pair of attachment brackets to which a base end section of the boom is attached such that the boom is free to be raised and lowered, and a frame body to which the pair of attachment brackets are provided with an interval in a left-right direction of the upper turning body. The frame body is formed of a plurality of divided frames arranged side by side in the left-right direction of the upper turning body, adjacent divided frames of the plurality of divided frames being separably joined to each other.

摘要： The packaged compressor includes: an exhaust duct having an exhaust port; a gas cooler arranged to be inclined with respect to the exhaust port in the exhaust duct; and at least one sound insulating plate arranged in a direction perpendicular to the exhaust port in the exhaust duct, the sound insulating plate configured to partition the exhaust port. In the packaged compressor, the exhaust port is partitioned into divided openings by the sound insulating plate. Of the divided openings, an area of a first divided opening provided on a side where a distance between the gas cooler and the exhaust port is shortest is larger than an area of a second divided opening.

摘要： An energy regeneration device capable of controlling flow of a working fluid discharged from an actuator while regenerating energy from the working fluid, and a work machine including the foregoing device, include a boom cylinder, an inertial fluid container, an oil tank, an accumulator, a low-pressure-side opening/closing device, and a high-pressure-side opening/closing device. A calculation unit calculates a duty ratio for opening/closing the low-pressure-side opening/closing device and the high-pressure-side opening/closing device in accordance with a desired flow rate of a hydraulic fluid discharged from the boom cylinder. A regeneration control unit selects alternately the low-pressure-side opening/closing device and the high-pressure-side opening/closing device as a destination with which the inertial fluid container communicates in accordance with the calculated duty ratio, and supplies the discharged hydraulic fluid to an accumulator.

摘要： This seamless wire containing welding flux is formed by filling a steel sheath with flux, the amount of Fe in the flux per total mass of the wire being 2-15 mass %, and the flux filling ratio being 10-30 mass %. When the amount (mass %) of Fe in the flux per total mass of the wire is X and the flux filling ratio (mass %) is Y, expression (1) is satisfied. By means of this seamless wire containing welding flux, variation in the flux cross-sectional area relative to the wire cross-sectional area, which is caused by a reverse airflow generated during a diameter reduction step, is reduced, and wire breakage during the diameter reduction step is prevented. Y>−2X+19 (1)

摘要： A casting method of an active metal includes, in an induction melting furnace using a water-cooled crucible, tapping a molten metal into a mold from a tapping hole provided at a bottom of the water-cooled copper crucible to cast an ingot of the active metal. In conducting the casting under a casting condition in which the ingot has a diameter (D) of 10 mm or more and a ratio (H/D) of an ingot height H to the ingot diameter D of 1.5 or more and a weight of the molten metal tapped in the casting is 200 kg or less, a temperature of the molten metal in the casting is set to be higher than the melting point of the active metal and a casting velocity V (mm/sec) is controlled to satisfy V≤0.1H in relation with the ingot height H by adjusting an opening diameter of the tapping hole.

摘要： A construction machine includes a boom, an operator cab, a distance sensor, a displacement detection unit, a storage unit, and a position information acquisition unit. The distance sensor has a predetermined field of view and acquires distance image data indicating a distance distribution of an environment around the operator cab. The storage unit stores initial position information of the boom. The displacement detection unit compares comparative position information of the boom, the comparative position information being acquired from the distance image data by the position information acquisition unit, with initial position information of the boom stored in the storage unit to detect a displacement of the distance sensor with respect to the operator cab when the boom is brought into an initial posture again after initial setting.
