Abstract: A collision prediction method for predicting a collision between a multi-joint robot and a nearby object includes a first acquisition step of acquiring configuration information of the robot and posture information of the robot; a second acquisition step of acquiring point cloud data including the robot and the nearby object; a classification step of classifying the point cloud data acquired in the second acquisition step into point cloud data corresponding to the robot and point cloud data corresponding to the nearby object, based on the configuration information of the robot and the posture information of the robot; and a prediction step of predicting a collision between the robot and the nearby object, based on a classification result obtained in the classification step.

Abstract: Reduced workload on a user can be achieved when a sensing-related teaching program is to be generated. A method for generating a teaching program that defines sensing operation includes a setting step for setting a sensing position at a surface of a workpiece, and a generating step for generating a teaching program of the sensing operation based on the sensing position set in the setting step. The sensing position is set within a range in which a maximum permissible amount for an error of the workpiece and a permissible range preliminarily defined with respect to a direction of the error are included in the surface.

Abstract: A work measuring method for measuring a work including a columnar member and a diaphragm and held by a positioner includes an acquiring step of acquiring point cloud data on a surface of the work held by the positioner and photographed in a predetermined direction, a detecting step of identifying a portion where distribution of the point cloud data changes in a three-dimensional coordinate system of the positioner and detecting the portion as a boundary position between the columnar member and the diaphragm, and a deriving step of deriving the number of columnar members and diaphragms included in the work on the basis of the boundary position detected in the detecting step.

Abstract: A microchannel heat exchanger is a heat exchanger for cooling hydrogen gas with a cooling medium, and includes a cooling side layer formed with a plurality of medium flow paths for flowing the cooling medium, and a high temperature side layer formed with a plurality of hydrogen flow paths for flowing the hydrogen gas and a first introduction port for flowing the hydrogen gas into the plurality of hydrogen flow paths. The first introduction port has a circular shape or an elliptical shape. An inflow end of each of the plurality of hydrogen flow paths is connected to a peripheral surface of the first introduction port. The hydrogen flow path extends from the first introduction port to the first lead out port without branching.

Abstract: A method for manufacturing a hot-dip galvanized steel sheet having a high Si content and good plating adhesion. The method for manufacturing a hot-dip galvanized steel sheet includes the following: hot-rolling a steel raw material having a Si content of 1.0 mass % or more and coiling a steel sheet at 500° C. to 700° C.; subjecting a surface of the steel sheet after the coiling to an oxidation treatment at a heating temperature of a steel sheet temperature of 750° C. or lower, and subsequently subjecting the surface to a reduction treatment; and subjecting the steel sheet after the reduction treatment to a hot-dip galvanizing treatment to form a Zn-plated layer on a surface of the steel sheet.

Abstract: A method for producing pig iron may use a blast furnace with a tuyere. Such a method may include: charging a first layer containing an iron ore material and a second layer containing coke alternately in the blast furnace; and reducing and melting the iron ore material in the charged first layer while injecting an auxiliary reductant into the blast furnace by hot air blown from the tuyere. An aggregate containing a reduced iron molded product obtained through compression molding of reduced iron may be blended into the first layer. The iron ore material may contain iron ore pellets as a principal material. An average basicity of the reduced iron molded product may be less than or equal to 0.5, and an average basicity of the iron ore pellets may be greater than or equal to 0.9.
