  • Publication number: 20040256890
    Abstract: A vehicle body structure in which a ridge of a front side member is continuous with a ridge of a dash brace to make it possible to efficiently transmit an impact force, and which is capable of realizing an intended deformation of the front side member suited to the impact force, while effectively utilizing a reaction force generated in a side frame member. A front portion of the dash brace is inserted into the front side member through a notch formed in a dash panel, and is overlapped with and spot-welded to a side face of the front side member, whereby the ridge of the front side member is directly continuous with the ridge of the dash brace.

  • Publication number: 20040201259
    Abstract: In a vehicle body structure, an accommodation concavity is provided in a floor panel. A pair of side members each having a nearly vertical first side surface portion extend bilaterally of the accommodation concavity. The floor panel is composed of a first floor panel having a first bottom surface portion serving as the bottom surface of the accommodation concavity, and second side surface portions erected in a nearly vertical direction from the first bottom surface portion and placed adjacent to the first side surface portions; and second floor panels each having a second bottom surface portion placed above the side member, and a third side surface portion erected in a nearly vertical direction from the second bottom surface portion and placed adjacent to and outwardly of the first side surface portion in a vehicle width direction.

  • Patent number: 6211166
    Abstract: Novel 5′-deoxy-cytidine derivatives represented by the general formula (I) wherein R1 is a hydrogen atom or a group easily hydrolyzable under physiological conditions; R2 is a hydrogen atom, or —CO—OR4 group [wherein R4 is a saturated or unsaturated, straight or branched hydrocarbon group consisting of one to fifteen carbon atoms, or a group of the formula —(CH2)n—Y (in which Y is cyclohexyl or phenyl; n is an integer from 0 to 4)]; R3 is a hydrogen atom, bromo, iodo, cyano, a C1-4 alkyl group [which may be substituted with halogen atom(s)], a vinyl or ethynyl group [which may be substituted with halogen atom(s), C1-4 alkyl, cycloalkyl, aralkyl, or aromatic ring which may have one or more hetero atom(s)], or an aralkyl group which may be substituted for use in medical therapy, especially tumor therapy.
