  • Patent number: 7883477
    Abstract: A human spinal column measuring and displaying system includes a spinal column measuring apparatus capable of measuring bending or a circumflex (twist) angle of the spinal column of the human body as a detaching amount measuring data from a reference value, an input apparatus for inputting gender, height data of the measurement subject, an image processing apparatus for inputting the detaching amount measuring data from the spinal column measuring apparatus and data from the input apparatus and generating a three-dimensional spinal column image of the measurement subject based on the detaching amount measuring data and the gender, height data of the measurement subject, and a display apparatus for displaying an image data from the image processing apparatus.

  • Publication number: 20080208080
    Abstract: The invention provides a human spinal column measuring and displaying system for calculating a measured data of three-dimensional coordinates and a circumflex angle of the spinal column by scanning a predetermined probe along the spinal column, and simulating a shape of the spinal column from the measured data to be able to display a three-dimensional pseudonymous spinal column image by utilizing a computer graphics.

  • Patent number: 5325575
    Abstract: A method and apparatus for assembling component parts of a product manufactured by assembling a plurality of kinds of component parts coaxially. First, component parts of one kind are held by a reference jig and component parts of another kind by a superposing jig. Then, the component parts held by the superposing jig are made to approach the component parts held by the reference jig and are fitted thereto by being pushed in by pushers, while the superposing jig is being guided through insertion of guide rods disposed on the reference jig into respective guide holes provided in the superposing jig such that the axis of each component part held by the superposing jig is aligned with the axis of each component part held by the reference jig, to thereby form subassemblies. Finally, component parts of still another kind held by another superposing jig are assembled to the subassemblies in a manner similar to the second step.
