Abstract:
In at least one aspect, a controlled decomposition oxidation (CDO) system is provided for abating perfluorocarbons (PFCs) that includes (1) an upstream portion including a first conduit adapted to convey a gaseous waste stream; (2) a thermal reaction chamber having an inlet coupled to the first conduit, a catalyst bed adapted to abate PFCs, and an outlet; and (3) a downstream portion including a second conduit having a first end coupled to the outlet of the thermal reaction chamber and having a portion, downstream from the first end, positioned proximate to the first conduit. The second conduit is adapted to convey a gaseous waste stream heated within the thermal reaction chamber to enable a transfer of heat energy from the second conduit to the first conduit so as to pre-heat the gaseous waste stream in the first conduit. Numerous other aspects are provided.

Abstract:
A method/system for performing dynamic re-scheduling of priorities of work-in-process in a fabrication plant for manufacturing of a product is provided. It reads a key stage report for the work-in-process and a master production schedule for the work-in-process from stored data. It generates a master production schedule report from the key stage report and the master production schedule following only Due_Date data for the work-in-process, and generates a work-in-process distribution matrix for integrating the master production schedule report with work-in-process quantity data within a deliverable cycle time; allocates selected lots from the work-in-process distribution matrix using a snake pattern method to allocate the selected lots from the matrix, and changes the due date for the selected lots of the work-in-process selected by the snake pattern method. It generates a final re-scheduling table for the work-in-process including the selected lots.
Abstract:
A method and an apparatus for preventing the misplacement of a cassette pod on the loadport of a process machine are described. In the method, a cassette pod that is equipped with an identification tag on a front panel is first provided, a process machine that is equipped with a loadport for receiving the cassette pod is then provided, at least one position verification block is mounted on the loadport at a first preset position, and then at least one position verification finger is mounted on the front panel of the cassette pod corresponding to the first preset position of the at least one position verification block such that when the cassette pod is placed on the loadport, the at least one position verification finger does not interfere with the at least one position verification block.
Abstract:
A method of taking a sliding exercise, which is taken on a training machine and the training machine has two pedals, includes the steps of: a) putting feet on the pedals; and b) reciprocating the feet in opposite directions or in the same direction. The feet respectively move in a curved path on a substantial horizontal plane. Therefore, the use's feet reciprocate forward/rearward and split to train user's muscles.
Abstract:
In some aspects, a method is provided for abating perfluorocarbons (PFCs) in a gaseous waste abatement system having a pre-installed controlled decomposition oxidation (CDO) thermal reaction chamber. The method that includes (1) providing a catalyst bed within the CDO thermal reaction chamber; and (2) introducing a gaseous waste stream into the CDO thermal reaction chamber so as to expose the gaseous waste stream to the catalyst bed. Numerous other aspects are provided.
Abstract:
A new data processing and display method for use in interactive manufacturing process management is achieved. A first variable value, such as WIP, for a manufacturing stage is uploaded from a database and is subtracted from a first target value to obtain a first variable variance. A first variable variance bar is displayed above a stage axis on a graphical display device and is non-filled if the first variable variance is positive and is filled if the first variable variance is negative. A second variable value, such as production moves, is uploaded and is subtracted from a second target value to obtain a second variable variance. A second variable value bar is displayed below the stage axis on the graphical display device and is non-filled. A second variable variance bar is displayed below the second variable value bar on the graphical display device if the second variable variance is positive.
Abstract:
Within both a stocker apparatus and a method for operating the stocker apparatus there is employed: (1) a minimum of six input/output ports; (2) an array of storage locations for storing an array of work in process (WIP) product units; and (3) a random access transportation means for transporting a work in process (WIP) product unit at least bidirectionally between the minimum of six input/output ports and a storage location within the array of storage locations. Within the stocker apparatus and the method, the minimum of six input/output ports provides for more efficient operation of the stocker apparatus.
Abstract:
Within both a stocker apparatus and a method for operating the stocker apparatus there is employed, in addition to: (1) a minimum of one input/output port; (2) an array of storage locations for storing an array of work in process (WIP) product units; and (3) a random access transportation means for transporting a work in process (WIP) product unit at least bidirectionally between the minimum of one input/output port and a storage location within the array of storage locations; (4) a controller for controlling the random access transportation means. Within the stocker apparatus and the method, the controller is programmed such that upon unavailability of the minimum of one input/output port and upon concurrent receipt of a request to retrieve a work in process (WIP) product unit stored within the array of storage locations to reposition the requested work in process (WIP) product unit to a designated storage location within the array of storage locations where it may be manually retrieved.
Abstract:
A system and a method are provided employing the concept of Budget Queue Time to define the priority of lots while distinguishing clearly between the controllable an uncontrollable portions of the remaining production time needed and to make the priority setting further meet the actual status. Two indices X and P are used concurrently to define the priority of a lot. X is the index of the delivery week which indicates the week in which the lot must be out of the fabrication process and P denotes the temporary priority according to the Budget Queue Time, but X is the dominant one of the two indices X and P. Use is made of the concept of remaining Budget Queue Time instead of traditional queue time of current stage for dispatching to reduce the variance of cycle time variance.
