Abstract: A top-blowing lance nozzle is configured to freely switch an adequate expansion condition so as to control an oxygen-blowing amount and a jetting velocity independently of each other without requiring a plurality of lance nozzles or a mechanically movable part. A lance nozzle is configured to blow refining oxygen to molten iron charged in a reaction vessel while a gas is blown from a top-blowing lance to the molten iron. One or more blowing holes for blowing a working gas are on an inner wall side surface of the nozzle, at a site where the lance nozzle has a minimum cross-sectional area in a nozzle axis direction or at a neighboring site of the site.

Abstract: An information processing apparatus includes an acquiring part, a copying part, and a controller. The acquiring part acquires a file structure at a migration source and an identification information item to identify a file at the migration source. Before migration of a content data item of the file at the migration source, the copying part copies the file structure and the identification information item to a migration destination in accordance with necessity or nonnecessity of copying the file structure and the identification information item, and the necessity or nonnecessity is determined by using an attribute information item of the file at the migration source and a history of access to the file at the migration source.

Abstract: An object of the present invention is to ascertain parts of an object that are approachable by finger portions of a hand mechanism. In an image information processing device, a housing container is retrieved from an image by using a first retrieval frame, and an object is retrieved from the image by using a second retrieval frame. A plurality of determination points are set in advance on the second retrieval frame, and a predetermined approach direction is set for each determination point. A determination is then made as to whether or not the finger portions of the hand mechanism can be caused to approach parts of one object, existing within the second retrieval frame, that correspond respectively to the determination points set on the second retrieval frame from the predetermined approach directions set in relation to the determination points.

Abstract: A hand mechanism grips an object more favorably, regardless of the attitude and surrounding conditions of the object. When an object is to be gripped by a hand mechanism having three or more finger portions, at least one finger portion among the three or more finger portions functions as a state-altering finger portion for altering the attitude or the position of the object while contacting the object, and at least two finger portions among the finger portions other than the finger portion functioning as the state-altering finger portion function as gripping finger portions for gripping the object in a state where the attitude or the position has been altered by the state-altering finger portion.

Abstract: A gripping system for gripping an object using a hand mechanism having at least two finger portions includes a specification unit that specifies a contactable portion and an unexposed portion, the contactable portion being a portion of the object that can be contacted by at least a first finger portion constituting one of the finger portions and the unexposed portion being a portion that is not exposed at the time of the determination, a first operation control unit that exposes the unexposed portion of the object, and a second operation control unit that grips the object in a state where the unexposed portion is exposed by bringing the first finger portion or the second finger portion into contact with the unexposed portion and bringing a finger portion other than the finger portion contacting the unexposed portion into contact with a predetermined surface of the object other than the unexposed portion.

Abstract: A design assistance system includes a component information management server and a design terminal. The component information management server includes an issue/measure information memory and a priority index memory. The issue/measure information memory stores a component to be used in a design assistance tool, an issue on the component, and measures to address the issue in association with each other. Each measure is at least one of addition of an addition target component and removal of a removal target component. The priority index memory stores a priority index in association with the addition target component and the removal target component. The design terminal includes a measure display that displays measures to address an issue on a focused component in a format based on the priority index associated with at least one of the addition target component and the removal target component included in each measure.
