An X-ray tube is provided as a source of X-rays for imaging systems such as computed tomography (CT) system. The X-ray tube includes an anode assembly comprising a target for emitting X-rays upon irradiation with an electron beam, a rotor shaft coupled to the target and a motor rotor system such that the rotor shaft is configured to rotate the target, and at least two duplex bearing assemblies to support the rotor shaft. The X-ray tube further includes a cathode assembly comprising a cathode configured to emit electron beam and a conical insulator isolating the cathode from ground potential.

A process for preparing Z-5-carboxymethylene-1,3-dioxolan-4-ones is provided which includes the steps of reacting a bis-ketal or bis-acetal of tartaric acid with a potassium containing base to form the carboxymethylene-1,3-dioxolan-4-one. A process for preparing HIV integrase inhibitors employing the carboxymethylene-1,3-dioxolan-4-one inhibitor is also provided.
摘要:
An apparatus for providing an isolated ground of a horn activation circuit of a steering wheel assembly comprising an airbag module, the apparatus comprising: an insulator for receiving and engaging a wire, wherein the wire and the insulator are configured to engage at least one securement member of the steering wheel assembly, wherein the airbag module is movably secured to the insulator for movement between a first position and a second position wherein the horn circuit is completed as the airbag module moves from the first position to the second position; and a wire harness electrically communicating with the wire and at least one contact portion of the airbag module, the at least one contact portion making contact with the wire as the airbag module moves from the first position to the second position.
摘要:
Apparatus for efficiently exciting an electrodeless lamp to produce visible light. A source of microwave energy is coupled to a cylindrical cavity which encloses an electrodeless lamp. The cylindrical cavity includes a sidewall and end wall which is made from a metallic mesh which passes light produced from the electrodeless lamp. The electric field intensity within the cylindrical cavity is increased in the region above the lamp center. The increased electric field intensity produces a more uniform temperature across the bulb service, increasing the rate of plasma heating of gas molecules in the lamp.

A purchase request system efficiently procures goods and services by recognizing purchase authority levels of users within an enterprise, division, or project team. Administrators establish authority levels to ensure that purchase requests within a user's authority level are automatically processed and submitted to vendors for fulfillment of orders, while purchase requests beyond a user's authority level are routed according to a determined protocol. Determined protocols include routing the purchase request to a designated user with a different authority level for disposition, rejection of the purchase request, or modification of the purchase request in accordance with the determined protocol. Users may select from multiple payment methods to complete a purchase transaction and may access the purchasing system in real time to determine the status of an order at any point in the life cycle of the purchase request, from submission of the request to payment for received goods and services.
