Abstract: A device comprises determining, if an instruction to open a first drawing file is accepted, whether the first drawing file and a second drawing file associated with the first drawing file have been edited at the same time; determining whether the second drawing file has been edited after previous editing of the first drawing file; determining, if the first drawing file and the second drawing file have been edited at the same time or if they have not been edited at the same time but the second drawing file has been edited after the previous editing of the first drawing file, whether there is a difference between attributes of identical drawing elements included in the respective drawing files; and executing, if there is a difference between the attributes, attribute change processing on the first drawing file.

Abstract: The present invention aims to increase the accuracy of an interference check and is characterized by including: a movable range calculation unit that, in a wiring model which is a three-dimensional shape model of wiring in three-dimensional model data, sets two fixed points in the wiring model as focal points and generates a set of predetermined points such that the sum of a distance from one of the focal points to a predetermined point and a distance from the other of the focal points to the predetermined point becomes the length of the wiring model; a movable range list generator that sets the inside of the set of predetermined points as a movable range of the wiring; and a display step unit that causes the set movable range to be displayed on a display unit.

Abstract: A printed wiring board includes an interlayer insulation layer, first pads positioned to mount a semiconductor element and forming a first pad group on the insulation layer, second pads forming a second pad group on the insulation layer and positioned along a peripheral portion of the first group, a first solder-resist layer formed on the insulation layer and having first openings exposing the first pads, respectively, and second openings exposing the second pads, respectively, conductive posts formed on the second pads through the second openings of the first solder-resist layer, respectively, and a second solder-resist layer formed on the first solder-resist layer and having a third opening exposing the first pads and fourth openings exposing surfaces of the posts, respectively. The second openings have a diameter greater than a diameter of the posts, and the second solder-resist layer is filling gaps formed between the second openings and the posts.

Abstract: In a fan motor, there are provided protruding portions provided integrally with a base member so as to face a magnet and protrude toward the magnet, and openings facing the magnet, in the base member made of magnetic material. As to the positional relation between the protruding portions and the openings, when the protruding portions are positioned corresponding to centers of the magnetic poles, the openings are positioned corresponding to boundaries between the magnetic poles. As to the positional relation between the protruding portions and the coils, when the protruding portions are positioned corresponding to centers of the magnetic poles, both ends of the coils are positioned corresponding to positions other than the boundaries between the magnetic poles.

Abstract: A compact fan motor including a motor body having a tubular case accommodating a rotor, a permanent magnet, and brushes, and a pair of spring terminals that are connected to the brushes, sticks out from a peripheral wall of the tubular case, and has elasticity in a direction perpendicular to an axis of rotation of a shaft; an impeller fixed to the shaft sticking out from a front end of the tubular case; a holder having a case accommodating portion that is provided in a housing accommodating the motor body and impeller and has an inner wall surface extending in the direction of the axis of rotation of the shaft, and a motor body insertion opening provided at an edge of the case accommodating portion; and a pair of conductors provided on the inner wall surface of the holder while contacting with the spring terminals.

Abstract: A dome-shaped diaphragm includes a convex portion; a base portion provided on an outer periphery of the convex portion; and a pressing force reducing portion provided in at least one of the convex portion and the base portion. Examples of the pressing force reducing portion may be a hole portion, a reduced thickness portion or any other feature that reduces the pressing force.
