  • Patent number: 5915562
    Abstract: A wafer container has an open front defined by a door receiving frame and a door sized for the door receiving frame. The door receiving frame has slots on opposite sides and the door utilizes latching linkages and lifting linkages cooperate to extend, lift, lower and retract the latching portions from the door into and out of latch receptacles on the door receiving frame. The door may also have passive wafer cushions or active wafer engaging arms which extend inwardly toward the wafers to secure said wafers when the door is in place. The latching linkages, lifting linkages, and where desired the retaining arms are linked to rotatable cammed members in the interiors if the door. The cammed member utilizes cammed surfaces configured to first extend the latching portions in a first direction into the latching receptacles and to then move the latching portions in a second direction normal to the first direction to pull the door inwardly and to seal the door to the container portion.

  • Patent number: 5871182
    Abstract: A modular tubing support and constrainment device for supporting and constraining tubing comprising a plurality of modular support trays, a module connector portion and a clamping portion. The modular support trays each incorporate a bottom portion for supporting the tubing and side constrainment portions to significantly constrain the amount of snaking by the tubing. The modular support trays further incorporate a plurality of apertures which are used by the module connector portions to connect and join the modular support trays into a continuous single unit. The apertures are also used by the clamping portion so that the clamping block may be secured to the modular support tray. The clamping block has an arcuate bore therethrough that is sized to fit snugly about and constrain the tubing. The bore may be lined with an elastomeric material to provide extra tube gripping potential.

  • Patent number: 5816410
    Abstract: The present invention is a shipping container for safely storing articles such as semiconductor wafers. The shipping container has two sidewalls sealingly connected to two end walls to form a generally rectangular interior wafer confinement area. A top cover and a bottom cover are removably attached to the container to protect the wafers during shipping and storage and provide access to the wafers for processing. The wafers are securely held in place in the carrier by a cushioning means to prevent damage to the wafers. Furthermore, the wafers are locked into place to prevent contamination by the wafers generating particles in the wafer confinement area by rubbing against the carrier. The cushioning means for accommodating the flexing of the cover supports and suspends wafers in the wafer confinement area. The cushioning means extends from the top cover and has a plurality of wafer engaging edges. Each edge is formed in a convex arcuate shape with respect to a centerline of the carrier.

  • Patent number: 5335696
    Abstract: The invention disclosed is a three-way weir valve. The valve housing has a common flow duct and two additional flow ducts, all connectable to external flow lines. A weir with two valve seats on opposite sides of the weir separates the common flow duct from the two additional flow ducts. Two coaxial diaphragms are arranged to engage with the weir valve seats. The common flow duct communicates with one flow duct over one of the weir valve seats and communicates with the other flow duct over the other weir valve seat. The two diaphragms are engaged with compressors connected to pistons engaged in pneumatic cylinders. An air line connects the two pneumatic cylinders. One diaphragm and compressor are biased towards engagement with its other weir valve seat resulting in a normally closed position. The other diaphragm is biased away from engagement with its weir valve seat resulting in a normally open position.
