  • Patent number: 8714562
    Abstract: A lip type end face sealing device having excellent sealability to different kinds of liquids on both sides in the axial direction and having excellent durability. A case is tight fitted to an inner peripheral face of a housing and includes case members. One pair of seal lips is integrally fitted to inner peripheral flange parts, positioned oppositely each other in the axial direction, and opened in a tapered shape. One pair of the seal lips is slidably contacted with flange parts of slingers tight fitted to an outer periphery of a rotary shaft.

  • Patent number: 7406361
    Abstract: V-CAD data is prepared by dividing external data 12 consisting of boundary data of an object into rectangular parallelepiped cells 13 having boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cells 13a positioned on the inner side of the object and boundary cells 13b including a boundary face, and a modeling unit quantity of a prototyping material 7 is changed in accordance with sizes of the internal cell 13a and the boundary cell 13b of a modeling portion. The prototyping material 7 is a resin, lumber powder, a low-fusing-point metal, metal powder, ceramics powder or a mixture of a binder and one of these materials, and its modeling unit quantity is set in such a manner that the modeling unit quantity is smaller than a capacity of a corresponding cell and does not protrude from the boundary plane of the cell.

  • Patent number: 7174236
    Abstract: (A) V-CAD data of an object (1) is prepared. (B) A processed surface shape after NC processing is predicted by simulation using the V-CAD data. (C) The object is subjected to NC processing by a predetermined NC program, and a processed surface shape after NC processing is measured, and (D) processing correction data is obtained from a difference between the processed surface shapes acquired by simulation and measurement, and the NC program is corrected based on the processing correction data. As a result, the ultra-precise processing is enabled even if a workpiece or a tool has low rigidity and an inconstant quantity of deformation.

  • Patent number: 7110852
    Abstract: There is prepared V-CAD data obtained by dividing external data 12 consisting of boundary data of an object into rectangular parallelepiped cells 13 having boundary planes orthogonal to each other in accordance with octree division and separating the respective divided cells into internal cells 13a positioned on the inner side of the object and boundary cells 13b including a boundary face, and mold data and mold processing data used to manufacture the object are generated from data of a reference plane which at least partially comes into contact with the object 1 and the V-CAD data. Further, in the mold processing data, a plurality of the processing tools 2 are selected in descending order of a size in accordance with sizes of the internal cells 13a of a processing portion, and the processing tool 2 is moved in a plane of the mold and in the thickness direction, thereby processing the mold.

  • Patent number: 7074354
    Abstract: In coloration of a shaped article composed of a curable resin, the addition operation can be reliably conducted and a reliable coloration effect can be obtained in both the single-color addition and in the multicolor addition. A liquid-phase, non-colored photo-curable resin is cured by irradiation with laser light and a lowermost layer 5n is formed. A liquid-phase, photo-curable resin is applied on the upper surface thereof and a colored layer 5n-1 comprising a cured non-colored region and a liquid-phase pool region is formed. A color ink is drop-wise added to the liquid-phase pool region. The pool region is irradiated with laser light and cured to the same hardness as that of the non-colored region. A block-like coating film having the prescribed thickness if formed from the surface coating film produced by the color ink covering the pool region. As a result, the formation of the next layer (colored layer 5n-2) on the upper surface of colored layer 5n-1 can be conducted without obstacles.

  • Patent number: 7008247
    Abstract: A jack having switch is constituted so that a movable armature is displaced so as to be separated from a fixed armature which contacts with the movable armature by insertion of a plug, the plug and the movable armature are brought into a contact state, and this state is maintained. The movable armature has two-pronged branch portions along a plug insertion/uninsertion direction, and the branch portions have plug contact portions which are expanded to be displaced outward by the plug to be inserted therebetween and hold the outside of the plug so as to be connected to the plug. The branch portions have fixed armature contact portions which contact with the movable armature arranged to be opposed to the branch portions when the plug is not inserted.
