  • Patent number: 4709834
    Abstract: Storage box including a box, a box door, a spring biased wafer retainer, and two locking clips. The storage box is used with standard mechanical interface (SMIF) transfer equipment, and is sealable, dust proof, and stackable. The box door includes cross-bar locators for cross-bar wafer cassettes. The box door will also accept other types of wafer processing cassettes. Each of the locking clips engage into a clip enclosure outboard of the box, and includes a locking slot for the locking clip, as well as a latch pin opening which provides for movement of the latch pin. A spring bar including parallel contact bars and configured spring bar ends positions to secure wafers in a contained wafer processing cassette.

  • 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: 4557382
    Abstract: A disk package for memory disks and the like and including a top cover, a disk cassette, and a bottom cover where the top cover includes sides with hooks which engage about catches on the box, and the bottom cover includes a channel which frictionally engages to the bottom edges of the box. The disk cassette supports a plurality of memory disks through perimeter contact of a rounded side and separated by teeth. The top cover includes a plurality of fingers which extend downwardly from the top cover, the fingers movable with respect to each other for engaging each disk independently of each other. The disks are separated by teeth having a rounded profile and a flat portion therebetween for perimeter contact with the disks, the teeth being longitudinal in length and running about the rounded sides and sides of the box.

  • Patent number: 4493418
    Abstract: Wafer cassette for processing of wafers which includes a plurality of open supported wafer dividers for supporting a plurality of wafers in alignment in opposing dividers of the cassette for automated processing of the wafers while in the cassette. The wafer cassette utilizes an H-bar end with a configured rod reinforced open front which is fully functional and strategically located. The dividers are supported by longitudinal horizontal supports secured to the ends providing for open area between each of the dividers for passage of liquids during automated processing. The cassette provides open area about the H-bar end. The rear end which includes a downward arch and through the dividers for open, non-restricted automated processing of wafers. The processing wafer cassette provides for "on-center" processing where the carrier center of gravity is on-center of the axis of centrifugal wafer processing machinery.
