摘要： A unique rotor assembly for an electrical machine is disclosed herein. The rotor assembly includes a shaft having an axis of rotation extending within the electrical machine. A central support is connected to the shaft at an intermediate position and a pair of opposing end plates are configured to clamp a plurality of laminate plates therebetween. The laminate plates and a sidewall of the end plates have a non-linear cross-sectional shape such that radial loading due to centrifugal force is transmitted from the laminate plates to the end plates during operation.

摘要： The present invention relates to articles comprising crosslinked polymer network comprising thioether crosslinks and process of making and using same. Such thiol-ene crosslinking reactions not only make the isocyanate crosslinking reaction unnecessary, but they also improve the article's strength due to chemical crosslinking between the article's resin layers, and reduce or eliminate post curing. Thus resulting in a sufficiently cured article in a much shorter time.

摘要： A semiconductor structure configured to implement an optically controlled field effect transistor (FET). In one embodiment, a normally-off, optically controlled FET is realized as a semiconductor structure comprising various regions configured to implement a voltage controlled, normally on, high voltage FET region having integrated thereon a photoconductive region configured to reduce a gate-to-source voltage of the FET in response to light incident upon the photoconductive region so as to turn the FET on.

摘要： A tool box with vertically stacked monolithic trays. Each tray has pockets specifically shaped to receive complementary tools. The trays have upstanding cantilevered posts, which can space apart the superjacent tray. Alternatively, the posts can be received in complementary sockets of superjacent trays to prevent undue lateral movement while in the tool box. The post and socket geometry can be constructed to index the order in which trays are stacked and index how individual trays are oriented for optimal and sequenced access to the tools.

摘要： A thermal desorption tube for chromatography and mass spectrometry analysis. The thermal desorption tube includes a sorbent and a plurality of focusing agents loaded at known, relative amounts onto the sorbent. Each focusing agent is a compound that chromatographically elutes within a retention time similar to a retention time of a target analyte and has a mass spectrum similar to a mass spectrum of the target analyte. The thermal desorption tube is configured to be further loaded with a sample having the target analyte.

摘要： The present invention relates to improved heterostructures and processes of making and using same. A peel and transfer process that disposes a first layer of boron nitride on said diamond substrate is provided. Such process yields heterostructures that having significantly improved mechanical and heat transfer properties. When such improved transistors and integrated circuits comprising such improved heterostructures are used in electronic devices, such devices are more efficient and can operate at higher frequencies.

摘要： The present invention relates to articles comprising fullerene supramolecular crystals and/or amorphous fullerene agglomerations, as well as carbon nanotubes (CNTs) and processes of making and using same. The disclosed articles have increased mechanical strength and flexibility while unexpectantly having an electrical conductivity that is similar to carbon nanotubes (CNTs) containing articles that do not contain fullerene supramolecular crystals and/or amorphous fullerene agglomerations. Such improved articles can be used in areas including cryogenics and aerospace. Applicants also provide an improved process of making the improved articles.
