  • Patent number: 9927014
    Abstract: A stator of a torque converter is divided into a first stator on an upstream side and a second stator on a downstream side, and the first and second stators are supported on a fixed part via first and second one-way clutches, respectively. Since, with regard to a blade of the first stator, when viewed in the axis direction, the blade tip part is inclined relative to the blade base part in the disengagement direction of the first one-way clutch, it is possible to ensure the blade area without increasing the dimension in the radial direction and the dimension in the axis direction of the blade of the first stator, and it is possible, by smoothly guiding oil along the blade of the first stator to thus suppress the occurrence of a vortex, to reduce energy loss in a low speed ratio region where the vortex easily occurs.

  • Patent number: 9267591
    Abstract: Among first and second stators of a torque converter supported on a fixed part by a one-way clutch corresponding to the stators, the number of second stator blades of the second stator on the downstream side in the direction of flow of oils larger than the number of first blades of the first stator on the upstream side, and the maximum value t2 for blade thickness of the second stator blade is smaller than the minimum value t1 for blade thickness of the first stator blade. Therefore, it is possible to ensure that there is a sufficient gap (?) between a trailing edge of the first stator blade and a leading of the second stator blade, thus preventing the flow of oil from being stopped by the gap (?), and it is possible to align effectively the flow of oil by means of the second stator blades.

  • Publication number: 20110046593
    Abstract: The present invention aims to provide a disposable diaper including leak barriers improved in its function to prevent loose passage from infiltrating thereinto and eventually leaching out therethrough. A disposable diaper (1) is provided with leak barriers (21) attached to opposite side edges of a crotch region (6) so that these leak barriers (21) may raise themselves on an inner sheet (3). The leak barriers (21) are formed of a nonwoven fabric made of thermoplastic synthetic fibers having a fineness in a range of 0.5 to 6 dtex and have a specific volume in a range of 9 to 13 cm3/g and a thickness in a range of 0.35 to 0.75 mm.
