Patent number: 9653331Abstract: Improvements in a single and dual stage wafer cushion is disclosed where the wafer cushion can use an edge hinge as a single first stage cushion and a second mid span hinge for the dual stage wafer cushion. This dual stage design gives two distinctly different cushioning forces as opposed to using a single stage design where the force is linear with the amount of compression that is being applied to the outer surfaces of the wafer cushion. The outside edge of the ring provides the greatest expansion such that only the outer edge of the ring makes contact with the outer edge of a wafer. The wafer cushion is a material that flexes and absorbs shocks before the shock is transferred to the wafer stack. The material minimizes debris or contaminants from embedding into the wafer cushion and also prevents sheading of material from the wafer cushion.Type: GrantFiled: February 16, 2011Date of Patent: May 16, 2017Assignee: Texchem Advanced Products Incorporated SDN.

Patent number: 8813964Abstract: Improvements in a semiconductor wafer container including improvements in side protection to the wafers, improved cover design to minimize rotation, a simplified top cover orientation mechanism and an improved bottom holding mechanism for automation. The side protection to the wafers is with multiple staggered inner and outer walls. The improved cover design improves alignment of the top and bottom housings and minimizes rotation of the housings in transit or motion. The housings have a recessed tab ramp feature with bi-directional locking that also increases the rigidity of the containment device when the two housings are assembled. The latching mechanism is located in a protective latch well that minimizes accidental opening of the latch(s). The improved bottom holding mechanism for automation is an integrated feature that is molded into the bottom housing and not assembled in a secondary operation.Type: GrantFiled: October 27, 2009Date of Patent: August 26, 2014Assignee: Texchem Advanced Products Incorporated SDN.

Patent number: 8556079Abstract: Improvements in a semiconductor wafer container for reducing movement of semiconductor wafers within a wafer carrier using flexible wall segments, panels or flexible inserts in the base member's main inner containment diameter. These walls allow a vertical containment surface to move and capture the entire stack of wafers rather than a few wafers. The surface that contacts the wafers moves uniformly inward. The wafer stack is secured by reducing or eliminating the gap between the wafer container and the wafer stack. Further improvements include the addition of a ramped engagement surfaces in the top and/or bottom cover that provides mechanical advantage for easier assembly of the top and bottom cover. This design also allows for automated loading and unloading of the wafer stack because once the top cover is removed, the flexible walls spring back outward. Thus providing a small gap in which to freely remove the wafers.Type: GrantFiled: March 29, 2010Date of Patent: October 15, 2013Assignee: Texchem Advanced Products Incorporated Sdn BhdInventors: James D Pylant, Alan L Waber, Christopher R Mack

Patent number: 5143316Abstract: A spool assembly having an elongated spindle and a pair of spaced end plates. Each end of the spindle is formed with a resilient locking arrangement and each end plate is formed with a centrally located opening. A locking arrangement is formed on the periphery of each opening to cooperate with a resilient locking arrangement on an end of the spindle. The resilient locking arrangement on an end of the spindle is engaged with the locking arrangement on the periphery of an opening in an end plate to connect the spindle and the end plates. A moveable slide is located within each end of the spindle to move axially relative to the spindle between a retracted position within the spindle and an extended position partially out of the spindle.Type: GrantFiled: May 9, 1990Date of Patent: September 1, 1992Assignee: Advanced Products IncorporatedInventors: Charles R.

Patent number: 4903913Abstract: An improved knock-down spool assembly is disclosed including a spindle body having specially configured end projections and a pair of end plates for receipt thereof. The end projections provide a restraining surface that, upon being yieldingly received by an opening in the end plates, is captured to secure the spindle thereto. A second embodiment is provided with radial extending yielding detents upon the spindle body and matingly positioned openings to further secure the spindle body with the end plates. The invention is snapped together to form an integral, yet readily disassembled, spool.Type: GrantFiled: August 2, 1988Date of Patent: February 27, 1990Assignee: Advanced Products IncorporatedInventor: James A.
