Abstract: Brightness profile data are extracted based on side view image data of an optical fiber, machine learning is performed by using teacher data indicating a correspondence relationship between brightness profile in a radial direction of the optical fiber and a type of the optical fiber, the teacher data being created based on the brightness profile data, a classification model is created to be able to determine the type of the optical fiber for an arbitrary optical fiber based on the brightness profile data indicating brightness profile in the radial direction of the arbitrary optical fiber, and the type of the optical fiber is determined for each of a pair of optical fibers by using the classification model based on the brightness profile data that is extracted based on side view image data of the pair of optical fibers as a target. The pair of optical fibers are fusion-spliced based on a fusion condition that is set in accordance with a combination of respective determined types of the optical fibers.

Abstract: A shape characteristic extractor decomposes and extracts typical shapes where element division is easy from shape data that indicates the shape of an object. An analysis mesh data generator generates analysis mesh data (element dividing information) for each of the decomposed and extracted shapes. Thus, the element dividing information can be generated even if the object has a complicated shape. Moreover, the element dividing information can be generated accurately and speedily.

Abstract: A heat pipe circuit board comprising: a heat pipe; at least one insulating layer; a circuit pattern provided on a surface of or inside the at least one insulating layer; and electronic components being mounted on the heat pipe through the insulating layer. The heat pipe is formed by jointing two plate members by friction stir welding, at least one of the two plate members being provided with a recess portion which is a fluid channel of a working fluid.
