  • Publication number: 20240161354
    Abstract: A physical property map image generation apparatus performs: acquiring, for each pattern of a material, physical property information indicating a physical property quantity for each physical property of a product; and generating a self-organizing map and a physical property map image. A position in a map space and a physical property vector indicating a value related to a physical property quantity for each type of physical properties of the product are assigned to each node on the self-organizing map. On the physical property map image 40, each of the nodes arranged in the map space is represented by a color assigned to that node. For each node, each of two or three base color components of a color assigned to the node is determined based on a value that a physical property vector assigned to that node indicates for a physical property corresponding to that base color.

  • Publication number: 20240153158
    Abstract: A map image generation apparatus acquires material specification information representing a material specification of a material and physical property information representing a physical property of a product. The map image generation apparatus generates a self-organizing map by using the physical property information. A position in a map space, and a physical property vector indicating, for each of a plurality of types of physical properties of the product, a value related to a physical property quantity of the physical property are assigned to each of nodes on the self-organizing map. The map image generation apparatus assigns, by using the material specification information, a specification vector indicating a value related to the material specification to each of the nodes. The map image generation apparatus generates a map image in which the nodes are clustered or colored based on the specification vectors.

  • Publication number: 20080206116
    Abstract: The present invention is relates to a method for alternately laminating each first metal sheet and each second metal sheet in three or more layers, wherein a melting point of the second metal sheet is higher than that of the first metal sheet, and welding them together by friction stir welding. Furthermore, under a state where those three or more metal sheets are so laminated that an edge of the first metal sheet protrude outward compared to an edge of the second metal sheet, the friction stir welding is executed by pressing a welding tool against only the edge of the first metal sheet.

  • Publication number: 20080076434
    Abstract: In a reconnection control method and device for mobile terminal which can automatically change an optimum reconnection time according to various states, a handover history of a mobile terminal is managed, a next handover destination cell of the mobile terminal is predicted from the handover history. When it is detected that the predicted handover destination cell corresponds to a radio wave-faulted area, a predetermined reconnection time for the mobile terminal is changed. When the radio wave-faulted area is a non-service area where a cell is not mounted, the predetermined reconnection time is reduced. When the radio wave-faulted area is a temporary radio wave-faulted area, the predetermined reconnection time is extended. When the radio wave-faulted area is a congestion area, the predetermined reconnection time is reduced.

  • Patent number: 7051916
    Abstract: The end of a hollow member 10 is abutted against the end of a hollow member 20. The end of a face plate 21 is supported on a protrusion 15. A small-diameter portion 52 of a rotary tool 50 is inserted into the abutted area, and the tool 50 is moved along the abutted region while being rotated in a clockwise direction as observed from the large-diameter potion 51. Thus, the pressure of mobilized metal is greater on the right side of the axial center of the rotary tool. The thickness of the member from the tip of the inserted small-diameter portion 51 to the hollow areas 10b and 10a is thicker at the right side where the pressure is higher, thus preventing metal from flowing out into the hollow region 10a.

  • Patent number: 7036707
    Abstract: Disclosed is a friction stir welding technique which avoids occurrence of a dent, in a joining region, extending to a level beneath the joined surfaces. At end portions of the frame members to be joined, at the joining region, thickened parts which project toward the rotary body joining tool are provided. Two adjoining thickened parts, of adjacent members to be joined, can form a trapezoid shape. The rotary body joining tool has a small-diameter tip portion and a larger diameter portion. The rotary body joining tool is inserted in the thickened parts. In a state where the rotary body joining tool has been inserted small-diameter tip end first, to a level where the larger diameter portion of the rotary body joining tool overlaps the thickened part but does not extend below the upper surface of the non-thickened surfaces of the members joined, the rotary body is rotated and moved along the joining region. Even when a gap exists between two thickened parts, a desirable joining can be carried out.

  • Patent number: 6821362
    Abstract: An auger composed of an auger body integrally formed with a spiral blade and at its opposite ends with a pair of shaft portions is manufactured by the steps of forming annular recesses on the shaft portions in a cutting process, building up an anti-abrasive and anti-corrosive alloy by plasma-arc welding in the annular recesses of the shaft portions and finishing each built-up portion of the alloy in a grinding process to form a journal portion on the respective shaft portions of the auger, wherein precipitation hardening stainless steel used as a base metal of the auger body is preheated for a predetermined time prior to the steps of plasma-arc welding of the alloy. In this manner, the stainless steel body is subjected to an aging heat treatment caused by (a) the preheating and (b) the subsequent welding heat generated during the plasma-arc welding process.
