A mixed matrix membrane is provided which comprises a continuous phase organic polymer and small pore alumina containing molecular sieves dispersed therein. The optical filter arrangement comprises a stack of a first optical layer and a second optical layer. A three-dimensional image preparation section prepares a three-dimensional image of the flexible medium either based on the three-dimensional transport position or the two-dimensional posture and on the dimensional information, and outputs the three-dimensional image as the result of the simulation. An armature having a first end and a second end is rotatably coupled at a first location to the crank, and is rotatably coupled at a second location to a second location on the rocker arm. Each these package handling devices may be used singly, or in combination with each other.
