  • Patent number: 4724963
    Abstract: Wafer processing cassette for the processing of silicon wafers, which includes a plurality of open, reinforced, dual cross-section profiled wafer dividers for structural integrity and for supporting a plurality of wafers in alignment in opposing mirror image dividers of the cassette for automated robotic processing of the wafers while in the cassette. The cassette utilizes a cross-bar end with a configured rod reinforced open cross-bar, which is fully functional and strategically located for structural integrity. The dividers are supported by two pairs of longitudinal horizontal supports secured to ends providing for a multi-level, flow-through, open area between each of the dual profile geometrically configured dividers for ease of entry and passage of liquids during automated processing. Rapid fluid flow and drying of the cassette is effected using extra smooth cassette surfaces, rounded edges, filled corners, drain recesses, drain scuppers, and ramped surfaces. The rear area includes a downward arch.

  • Patent number: 4669612
    Abstract: Processing cassette for processing of hard rigid memory disks including a plurality of open supported opposing disk dividers for supporting a plurality of disks in alignment by the dividers of the cassette. The cassette is intended for use in automated robotic processing of the disks while in the cassette. The wafer cassette includes similar mirror image like opposed ends with deep wide downwardly inverted arches. The dividers are supported by two pairs of horizontal supports secured to the ends, providing for both upper and lower open process wash areas between each of the dividers for passage of liquids during automated robotic processing. Surfaces of the cassette are non-porous and extremely smooth. All edges and corners are radiused facilitating quick and effective drying of the cassette during robotic processing. On-center processing is provided for the disk processing cassette, where the carrier center of gravity is on-center for an axis of centrifugal disk processing machinery.

  • Patent number: 4634004
    Abstract: Magnetic tape security housing including two mirror imaged halves which mate together with opposing hooks and latches forming a magnetic tape security package, with combination U-shaped carrying handle and package hanging ports, for encompassing a cardboard box containing a magnetic tape, such as a video game tape, cassette tape, a VHS or Beta video tape, floppy disks, or other like valuables. The mated housings engage integrally together to form a package to protect a box containing a magnetic tape or the like. The only way that the box can be removed from the package is through destruction of the housing members. The package is non-openable except through total destruction of one or both of the housing members.

  • Patent number: 4488834
    Abstract: A method for developing, evacuating, using, sealing, and re-entering multiple stacked cavities which are created from a single well in salt deposits. The cavities are created in a salt deposit by circulating raw water through concentric casing strings in the well. Each of the cavities is evacuated of liquids prior to use. After storage material is injected into a cavity, the cavity is sealed by setting a plug in the well bore above the top of the cavity. The cavities may be re-entered by drilling out the plug or by drilling a directional well directly into the cavity.
