Abstract: A semiconductor wafer, substrate, or reticle storage or shipping device that includes a photochromic indicator of exposure to undesired electromagnetic radiation. The present invention includes the incorporation of a photochromic material into the plastic used to fabricate at least a portion of a semiconductor wafer, disk, or reticle shipping or storage containers. The container may include photochromic material in the form of a transparent window or a larger portion of the container. The photochromic material may change color or darkness in response to exposure to a selected range of wavelengths of light.

Abstract: A package for storing and shipping semiconductor wafers or memory disks is disclosed. The carrier includes a bottom, a cover and a cassette. An improved closure arrangement is provided that not only secures the cover to the bottom, but also compensates for pressure differentials between the inside and outside of the package and provides for improved drainage during washing operations.

Abstract: An improved cable guard for a compound archery bow having a riser, upper and lower limbs extending from the riser, pulleys mounted on the limbs, one or more cables trained around the pulleys and spanning the limbs, and a bowstring extending between the limbs. The cable guard has a one-piece construction including integrally joined mounting and cable guard portions. The cable guard portion extends rearwardly from the riser offset from the plane of the bow. To minimize lateral deflection caused by side loads generated by the deflected cables, the cable guard portion has a beam height which is increased at the mounting portion joint and continually decreases towards the free end of the cable guard.
