  • Patent number: 8931418
    Abstract: A bodyshell of a railcar includes side outside plates, end bodyshells, and guiding plates. The side outside plate are located at both end portions of a carbody in a vehicle width direction. The end bodyshell includes an end outside plate and a corner post. The end outside plates are located at both end portions of the carbody in the longitudinal direction. The corner posts are located at four corners of the carbody. The corner post is joined to the adjacent end outside plate and the adjacent side outside plate. The guiding plate is provided at the side outside plate so as to cover the corner post from a vehicle exterior. The guiding plate includes an inclined portion and a joining portion. The inclined portion is provided in front of the corner post and inclined to the rear side toward the side outside plate.

  • Publication number: 20140018510
    Abstract: The present invention is directed to providing a safe medical adhesive, a cured body of which is hard to be degraded and decomposed and thus stable and the cured body generates less amount of acid, aldehyde, etc. due to degradation/decomposition. The medical adhesive includes a hydrophilic urethane prepolymer (UP) obtained by reacting a polyisocyanate component (A) containing a fluorine-containing non-aromatic polyisocyanate compound (A1) as an essential ingredient and a polyol component (B) containing a hydrophilic polyol (B1) as an essential ingredient, wherein a chlorine content in a chlorine-containing organic compound based on the weight of the hydrophilic urethane prepolymer (UP) is 0.005 wt % or less.

  • Patent number: 7926370
    Abstract: A rotation and extension/retraction link mechanism which realizes a rotary joint having a virtual rotation axis is provided. A rotation and extension/retraction link mechanism 1 is configured so that a first link 5 having a first virtual center line 3 and a second link 9 having a second virtual center line 7 are coupled through a rotation and extension/retraction joint mechanism 11. The rotation and extension/retraction joint mechanism 11 is configured to couple the first link 5 and the second link 9 so that when the second virtual center line 7 rotates relative to the first virtual center line 3 from a state where the first virtual center line 3 entirely overlaps with the second virtual center line 7, while crossing the first virtual center line 3, an intersection between the first virtual center line 3 and the second virtual center line 7 is displaced on the first virtual center line 3 by a predetermined distance corresponding to an angle of the rotation.
