Abstract: An extraction method is aimed at extracting an object component by transferring the object component from a first liquid containing a microorganism and the object component to a second liquid to which the object component can be transferred and that is capable of causing phase separation from the first liquid, with use of a flow channel including a merging part, a flow part, and an outlet part. The extraction method includes a step of supplying the first liquid to the merging part, a step of supplying the second liquid to the merging part, a step of passing the first liquid and the second liquid supplied to the merging part, through the flow part, in a state where a phase of the first liquid and a phase of the second liquid are separated from each other, a step of discharging the first liquid and the second liquid passed through the flow part, from the outlet part, and a step of collecting the first liquid and the second liquid discharged from the outlet part, into a collector.

Abstract: Shape data relative to a hemmed edge in view of production technique requirements is added to shape data relative to a design surface using a CAD system. Curvatures of curved lines, curvatures of curved surfaces, offsets and distances between shape surfaces, and angles between shape surfaces of the shape data are analyzed and verified.

Abstract: After fillet surfaces have been generated with respect to surfaces, a joint surface is generated between the fillet surface. New fillet surfaces are determined from the fillet surfaces and the joint surface. Then, a phase relationship is established between data relative to the surfaces and data relative to the new fillet surfaces, and these data are combined into shape data including data of fillet surfaces which are capable of representing the complete shape of a product.

Abstract: A method of and an apparatus for producing solid models, in which input data consisting of the coordinates of terminal points and a formula of a curved line of each arc of a given wire frame model is read. The coordinates of a node and a set of arcs connected thereto are determined based on the input coordinates of the terminal points. A set of arcs looping around an indivisible surface of the wire frame model are specified as the outermost line surrounding the whole wire frame model. A region of the wire frame model surrounded by the outermost line or division lines is divided into two new partial wire frame models by a new division line starting from a node located on the outermost line or the division lines, traversing the region without making a loop, passing along each of the arcs included in the region only once, and reaching another node located on the outermost line or the division lines.
