  • Patent number: 10413896
    Abstract: The ion exchange membrane according to the present invention comprises a layer A comprising a fluorine-containing polymer having a sulfonic acid group and a layer B comprising a fluorine-containing polymer having a carboxylic acid group, wherein an ion exchange capacity of the layer B is 0.81 mEq/g or more, and a value of (an ion cluster diameter of the layer B)/(an ion cluster diameter of the layer A) is 0.67 to 0.89.
    Type: Grant

  • Patent number: 7384612
    Abstract: An exhaust cleanup filter which, even if the exhaust temperature is low as during vehicular driving under low load, can trap PM efficiently to prevent clogging by PM buildup and which also is effective in purifying the exhaust from a diesel engine that does not use any burner or heater to remove PM. The cleanup filter is for purifying the exhaust from diesel engines and comprises particulate ceramic porous bodies that have a three-dimensional network structure, as well as artificial pores and communication channels in the interior, with some of the pores being partially exposed on the surfaces of the porous bodies.

  • Patent number: 4439092
    Abstract: An apparatus for unloading a workpiece from a pressing machine includes a power cylinder mounted on the pressing machine and having a horizontally movable piston rod. An operating rod is mounted on the pressing machine in parallel relation to the piston rod and is horizontally movable. The stroke of the operating rod is shorter than the stroke of the piston rod. A linkage assembly is attached to the forward ends of the piston rod and operating rod so that the operating rod is moved horizontally together with the piston rod during its stroke. The linkage assembly has a forward end which is vertically moved toward and away from a die of the press upon the horizontal movement of the piston rod relative to the operating rod at a final portion of the extending stroke thereof and at an initial portion of the retracting stroke thereof. A plurality of suction cups are connected to the forward end of the linkage assembly.
