Abstract: An information processing system (SYS) includes: a plurality of gate apparatuses (1) that are respectively placed at a plurality of lanes (L) through each of which a target person (P) can pass; a thermal camera (3) that is configured to generate a body temperature information (IMG_T) indicating a body temperature of the target person by capturing an image of the target person included in an imaging range (TRG) thereof, the imaging range including at least a part of each of the plurality of lanes; and an information processing apparatus (4) that obtains the body temperature information from the thermal camera.

Abstract: An information processing apparatus (2) includes: an obtaining unit (211) that obtains an infection information relating to an infected person that catches an infection disease; and an identifying unit (213) that identifies, as a contact person that possibly contacts the infected person, at least one target person staying in a stay area in which the infected person stays in at least a part of a time period during which the infected person stays in the stay area from a plurality of target persons based on the infection information and a history information (221) that is generated based on a plurality of target person images (IMG) that indicate the plurality of target persons, respectively.

Abstract: A part machining cost estimating server includes: an inputted estimate data accepting unit that accepts inputted estimate data; a determination unit that determines whether the inputted estimate data satisfies predetermined estimate conditions or not; an estimate reference price memory unit in which estimate reference prices derived in accordance with first predicted data of the inputted estimate data in advance based on experiences are stored in association with the first predicted data of the inputted estimate data; an estimate coefficient memory unit that derives coefficients in accordance with second predicted data of the inputted estimate data in advance based on experiences are stored in association with the second predicted data of the inputted estimate data; an estimated sum calculating unit that calculates an estimated sum by multiplying the estimate reference price by the coefficient; and an estimate number assigning unit that assigns an estimate number to the estimated sum.

Abstract: A manufacturing method for a composite steel part including preparing an intermediate product in which an extra portion, which has a thickness equal to or more than that of a carburized layer to be formed in a subsequent carburizing step, has been added to a welding expected portion, carburizing the intermediate product by heating to an austenitizing temperature or more in a carburizing atmosphere, then cooling the intermediate product at a cooling rate less than a rate at which martensitic transformation occurs and without completing structural transformation due to the cooling, quenching a portion of the intermediate product after heating to an austenitizing range by high-density energy and thereafter cooling to cause martensitic transformation to form a carburized quenched portion, removing an extra portion of the intermediate product; and then welding a second steel part to the welding expected portion.

Abstract: A supporting structure comprises a shell and a plurality of support members which are independent of each other, inserted in the shell and arranged so that the flexural rigidity is smaller in the water flow than in a perpendecular to the water flow. The supporting structure supports one place of an axial-flow bulb turbine which is to be supported at two places spaced in the water flow direction from each other. The support structure is more flexible in the water flow direction than in the perpendicular direction to the water flow, so that small bending stresses are induced in the support structure and the axial stresses induced in the support structure by the weight and the buoyancy acting on the turbine and the bending stresses induced in the support structure by axial deformation of the turbine are kept below an allowable stress of material constituting the support structure.
