  • Patent number: 11796980
    Abstract: When the temperature history in a fine mesh is obtained for the entire modeled object, it takes a huge amount of time in calculation. In order to solve the problem, An additive-manufactured object design supporting device, comprising: an analysis unit configured to analyze a modeling process of a macro-region and a micro-region by using a product shape, a material condition, and a modeling condition of a modeled object as input; a temperature history extraction unit configured to extract, from a temperature analysis result of the macro-region, a local temperature history by referring to a database that stores a temperature history of the micro-region; a mapping unit configured to map a structure distribution obtained from a temperature history distribution of the modeled object to the modeled object; and an extraction unit configured to extract a defective structure that does not satisfy a structure condition by using an allowable structure condition as input.

  • Patent number: 9792401
    Abstract: The insulation distance check device comprising: a unit which designates a high potential component, a conductive component and an insulation component to 3D CAD data; a unit which designates a distance condition; a unit which superimposes a layer surrounding the high potential component and creates a layer map associating the layer with a first distance; a unit which determines a second distance associated with the layer contacting with a portion of the conductive component, the second distance being a distance between the high potential component and the portion of the conductive component; a unit which compares the second distance and the distance condition; and a unit which displays at least one of a region occupied by the portion of the conductive component, on which the second distance having been determined to dissatisfy the distance condition is based; and a path connecting the high potential component and the conductive component.

  • Patent number: 9593695
    Abstract: A fan device mounting structure is provided, which is capable of sufficiently suppressing transmission of vibrations in X, Y, and Z directions generated from a fan device, that is, all translational-direction vibrations and all axial-rotation-direction vibrations, to a chassis in which the fan device is mounted. The fan device mounting structure includes: a fan device 1; a chassis 4 in which the fan device 1 is mounted; and at least a pair of flat springs 2, each of which has its one end attached to the fan device 1 and extending outwards from the fan device 1 and bending and has the other end attached to outside a fan device located area, wherein both opposite faces of the fan device 1 facing each other are supported by the respective flat springs 2 and attached to the chassis 4 at positions separate from each other.

  • Publication number: 20130303294
    Abstract: A thread repair tool for repairing damaged threads on a screw is disclosed. The thread repair tool includes a tool body and plural rollers. The tool body has at least one surface provided with a thread repair blade that has a tooth pitch identical to a thread pitch of the threads to be repaired. The rollers are separated from the tool body by a gap. The thread repair tool further includes an adjusting means for adjusting the gap so as to hold the screw between the tool body and the rollers.

  • Patent number: 5958594
    Abstract: A urethane-forming curable composition which has a low viscosity and therefore can sufficiently flow around to details or minute cavities of electric or electronic parts or devices to seal the same and which can give flexible curing products excellent in heat resistance, hydrolysis resistance (wet heat resistance) and moistureproofness and capable of preventing hardness changes as well as reductions in insulating performance over a long period of time even under severe conditions and therefore can reliably protect the electric or electronic parts or devices. A hydrogenated OH-containing liquid polyisoprene (X) and a polyester polyol (Y) which is liquid at ordinary temperature and is constituted of fatty acid units (A) and polyhydric alcohol units (B) and which has an iodine value of not more than 50 are combinedly used as the polyol component. The fatty acid units (A) of this polyester polyol (Y) at least partly comprise hydroxy fatty acid oligomer (at least dimer) units (a).
