  • Patent number: 10518809
    Abstract: Rear side members include: side walls inclined outward in the vehicle width direction; and side wall flanges bent from front ends of the side walls, and extending inward in the vehicle width direction. A center floor cross member has a side wall contacting with the side wall flanges of the rear side members. Reinforcement members include: side walls extending to the side wall of the center floor cross member; and flanges bent from rear ends of the side walls, extending outward in the vehicle width direction, and at least partially coinciding with the side wall flanges of the rear side members in the vehicle width direction with the side wall of the center floor cross member interposed therebetween.

  • Patent number: 10340621
    Abstract: A housing (10) includes a housing body (11) and a receptacle (12) projecting forward from the housing body (11). The housing body (11) includes first cavities (13) into which first male terminals (70) are inserted, and second cavities (14) into which second male terminals (80) are inserted. Each second male terminal (80) includes a second tab (82) longer than a first tab (72) of each first male terminal (70). Recesses (23) are provided on a front surface (17) of the housing body (11) around openings of the second cavities (14) and are recessed farther rearward than areas around openings of the first cavities (13). A moving plate (40) is movable from an initial position to a connection position in the receptacle (12). The moving plate (40) has interpolar partitioning portions (52) configured to partition between the adjacent second tabs (82) by entering the recesses (23) at the connection position.

  • Patent number: 10293145
    Abstract: One embodiment provides a balloon catheter which has an inner tube having a main lumen and an outer tube which forms an expansion lumen. A part of the inner tube is connected to the outer tube at a position closer to the proximal end than a balloon, a side hole is open at the connection section, and a weak section is provided to the inner tube a position closer to the distal end than the side hole. The weak section has lower rigidity than the remaining portion of the inner tube. When the balloon is expanded by fluid supplied to the expansion lumen, the weak section is pressed by the fluid pressure to thereby close the main lumen of the inner tube.

  • Patent number: 8551133
    Abstract: An object of the present invention is to provide a balloon catheter integrated with a guidewire in which a stepped portion is prevented from being formed between a coil portion of the guidewire and a front end portion of the balloon catheter and thus crossability of the balloon catheter is improved. The balloon catheter includes a transition part made of resin that smoothly connects an external shape of an outer coil of a front end coil part and an external shape of a tip portion of a front side inner shaft.

  • Publication number: 20120271232
    Abstract: A catheter includes an inner shaft having a tubular inner layer, a braid arranged on the tubular inner layer, and an outer layer made of resin and covering the braid. The catheter also includes a tubular tip attached to a front end of the inner shaft, the tubular tip has a portion that is thicker than the front end of the inner shaft, and an outer diameter that decreases toward a front end thereof.

  • Publication number: 20110319922
    Abstract: An aspect of the present invention is a balloon catheter integrated with a guidewire. An object thereof is to provide a balloon catheter allowing smooth connection between a coil portion of the guidewire and a front end portion of the balloon catheter by preventing the stepped portion from being formed therebetween and allowing the tip portion of the guidewire to sufficiently exhibit characteristics thereof without providing any additional element. The balloon catheter includes: a protruding portion formed of an inner coil which is arranged inside a front end coil part and which extends from a rear end of the front end coil part to surround a core shaft; and a front end opening part of a guidewire lumen that is provided at a front end of a catheter body and into which the protruding portion is inserted.

  • Publication number: 20110144538
    Abstract: Provided is a guidewire effectively usable for a retrograde approach. A guidewire has a body portion, and a first tip portion and a second tip portion provided at ends of the body portion. Flexural stiffnesses of the first tip portion and the second tip portion increase in a continuous or stepwise manner from the respective tips of the first and second tip portions toward the body portion. The flexural stiffness of the first tip portion is not smaller in value than the flexural stiffness of the second tip portion in first distance ranges from the respective tips of the first and second tip portions toward the body portion. The flexural stiffness of the first tip portion is smaller in value than the flexural stiffness of the second tip portion in second distance ranges beyond the respective first distance ranges of the first and second tip portions toward the body portion.

  • Patent number: 4978754
    Abstract: A process for the preparation of an N-substituted unsaturated carboxylic acid amide represented by the following formula: ##STR1## wherein R.sup.1 means a hydrogen atom or methyl group Y denotes a methylene group, oxygen atom or methylimino group, m and n stand individually for an integer of 0 to 5, and m+n is an integer of 3 to 5. The process comprises reacting a specified .beta.-alkoxy-substituted carboxylate with a specified cyclic amine to form a .beta.-alkoxy-substituted carboxylic acid amide compound and then removing an alcohol from the carboxylic acid amide compound in the presence of a basic catalyst to form an unsaturated group.
