Abstract: To provide a volume-type optical element in which a self-cloning photonic crystal is used. An optical element is provided with half-wave plates of photonic crystals formed on the xy plane and laminated in the z-axis direction in a three-dimensional space x, y, z. The groove direction of the photonic crystals is a curved line, and the angle in relation to the y-axis direction changes continuously in the range of 0°-180°. Light entering the optical element in the axial direction is emitted from the optical element upon being divided and converted into clockwise circularly polarized light in the direction facing the x-axis by a given angle from the z-axis and anticlockwise circularly polarized light in the direction facing the ?x-axis by a given angle from the z-axis. Laminating or placing a quarter-wave plate comprising a photonic crystal on one or both surfaces makes it possible to divide light entering from the z-axis direction of the optical element into two orthogonal linearly polarized lights.

Abstract: A vaporized-fuel processing device for an engine stabilizes the idling operation wherein vaporized fuel within a fuel reservoir is adsorbed to an adsorbing member of a canister. While the engine is in operation, air is sucked from an air inlet into the canister with the intake-air negative pressure produced in an intake-air passage. This air separates the vaporized fuel adsorbed to the adsorbing member of the canister. Purge gas resulting from mixing the vaporized fuel into the air is sucked from a purge-gas sucking port into the intake-air passage. A throttle valve is arranged in a throttle intake-air passage of a throttle body. An intake-air pipe is disposed intake-upstream of the throttle body and is communicated with the throttle intake-air passage. The intake-air pipe has a peripheral wall to which a purge-gas sucking pipe is detachably attached. The purge-gas sucking port is provided within the purge-gas sucking pipe.
