A three-dimensional object is manufactured from a powder of polymer material by selective sintering process by means of electromagnetic radiation of the powder, wherein the powder comprises a preselected polymer or copolymer and is subjected to selective sintering such that the manufactured three-dimensional object has a final crystallinity which is in such a range that the balance of properties, in particular mechanical properties including Young's modulus, tensile strength and elongation at break, is improved.

A polyetheretherketone film is used in the consolidation of a prepreg so that the film becomes incorporated into the consolidated prepreg, defines an outer layer of the consolidated prepreg and therefore provides the consolidated prepreg with advantageous properties. In one embodiment, a film may be used as a bagging material. In this embodiment, prepreg is positioned in a mould to define a precursor of a composite material. A bagging film is positioned next to the prepreg and a vacuum is applied via port to evacuate the space between the prepreg and film and induction heating is used to cause the resin in the prepreg to melt. In addition, the film yields and draws and this stretched film will cover the prepreg and act as a bagging material. Another embodiment addresses the problem of insertion and/or removal of an inflatable bladder in the manufacture of hollow articles and utilizes a gas filled thermoplastic bag.

A method of fitting a compressed component, for example a pipe, in a receiver, for example a bore, comprises compressing a selected component which is made out of a polymeric material having a glass transition temperature of at least 100° C., for example polyetheretherketone; arranging the compressed component in position within a receiver; and subjecting the compressed component to conditions, for example of temperature and/or pressure, whereby the compressed component expands.

One embodiment of the present invention provides a system that enhances throughput and fault-tolerance in a parallel-processing system. During operation, the system first receives a task. Next, the system partitions N computing nodes into M set-aside nodes and N-M primary computing nodes, wherein M≧1. The system then processes the task in parallel across the N-M primary computing nodes. While doing so, the system proactively monitors the health of each of the N-M primary computing nodes. If the system detects a node in the N-M primary computing nodes to be at risk of failure, the system copies the portion of the task associated with the at-risk node to a subset of the M set-aside nodes. The system then processes the portion of the task in parallel across the subset of the M set-aside nodes while the N-M primary computing nodes continue executing.
摘要:
An inventive method in an integrated circuit (IC) manufacturing process for using data regarding repair procedures conducted on ICs at probe to determine whether any further repairs will be conducted later in the manufacturing process includes storing the data in association with a fuse ID of each of the ICs. The ID codes of the ICs are automatically read, for example, at an opens/shorts test during the manufacturing process. The data stored in association with the ID codes of the ICs is then accessed, and additional repair procedures the ICs may undergo are selected in accordance with the accessed data. Thus, for example, the accessed data may indicate that an IC is unrepairable, so the IC can proceed directly to a scrap bin without having to be queried to determine whether it is repairable, as is necessary in traditional IC manufacturing processes.

Microelectronic imaging devices and associated methods for attaching transmissive elements are disclosed. A manufacturing method in accordance with one embodiment of the invention includes providing an imager workpiece having multiple image sensor dies configured to detect energy over a target frequency. The image sensor dies can include an image sensor and a corresponding lens device positioned proximate to the image sensor. The method can further include positioning standoffs adjacent to the lens devices while the image sensor dies are connected to each other via the imager workpiece. At least one transmissive element can be attached to the workpiece at least proximate to the standoffs so the lens devices are positioned between the corresponding image sensors and the at least one transmissive element. Accordingly, the at least one transmissive element can protect the image sensors while the image sensor dies are still connected. In a subsequent process, the image sensor dies can be separated from each other.
