摘要:
All optical clock recovery includes a transmitter for generating an optical timing signal. The transmitter includes a semiconductor laser for the production of a dynamically synchronizable timing signal, the laser having an external resonator for feedback of the timing signal to the laser, the feedback having a delay time greater than a relaxation oscillation time for the laser, and the laser outputting an optical timing signal having a characteristic dynamic. The transmitter supplies the optical timing signal to a receiver configured to receive the timing signal and to synchronize to the laser on receipt of the timing signal, such that the receiver outputs a recovered timing signal having the characteristic dynamic. A number of receivers may be provided in sequence along an optical path, each receiver configured to receive the timing signal originally outputted with the characteristic dynamic from the transmitter, and synchronized to the transmitter on receiving the signal and thereby outputting a recovered timing signal having the characteristic dynamic. All optical clock recovery is provided without increased electronic complexity and avoids thermal drift.

A method for treating a glass substrate and a black matrix thereon for a flat panel display is provided. In one application, the treatment of the glass substrate and black matrix is performed prior to delivery of ink to the glass substrate by an inkjet printing system. The black matrix and glass substrate are exposed to a surface active compound. In one aspect, exposing the black matrix and the glass substrate to a surface active compound modifies the surface energy of the black matrix, the surface energy of the glass substrate, or both. In another aspect, treating the black matrix and the glass substrate enhances the formation of color filters having sub-pixel wells that have a substantially uniform distribution of ink therein.

The disclosure relates to a vaporizer valve which accepts a carrier gas and a pressurized liquid and forms a mixture of the carrier gas and vaporized liquid. An internal cavity receives the carrier gas through a carrier aperture and the liquid through a liquid aperture, and the mixed gas and vapor are exhausted out of the cavity via a third aperture. A moveable diaphragm disposed adjacent to the liquid aperture forms a vaporization region having a pressure gradient. The liquid passing through this pressure gradient vaporizes due to expansion. By controlling the diaphragm position with a feedback control circuit responsive to a liquid flow rate monitor, the liquid flow rate may be controlled independently of the carrier gas flow rate.

A system, method, and computer program product utilizing a default user ID, such as “help,” that has no assigned password. When the user logs into the computer using this ID, their login is “captured” and a crippled windows manager is started along with a web browser pointed to a specific URL. The user has no ability to manipulate the operating system, the local file system, or even the web browser. All the user is able to do is interact with the automated reset page(s) on the network authentication server. Once the user has completed her password reset and closed the browser, the user's web session is logged out and the user can now log in with her new password and her original userid.

In a first aspect, a system is provided. The system includes (1) a stage adapted to move a substrate relative to print heads during printing; (2) at least one print head suspended from a support above the stage and adapted to be moveable in a plane above the stage; (3) a controller operable to rotate the print head about a center of the print head; and (4) an imaging system adapted to capture an image of the print head and to determine a center point of the print head based upon images of the print head captured as the print head is rotated. Numerous other aspects are provided.

A method and apparatus for dechucking a substrate is provided. In one embodiment, a processing chamber is provided that includes a grounded chamber body having a substrate support assembly disposed in an interior volume. A dechucking circuit selectively couples the substrate support assembly to ground or to a power source. In another embodiment of the invention, a method for dechucking a substrate includes the steps of completing a plasma process on a substrate disposed on a grounded substrate support assembly, disconnecting the substrate support assembly from ground, and applying a dechucking voltage to the substrate support assembly.

An exemplary method and system for reducing or eliminating the formation of solid precipitates/deposits of a flowing fluid, such as oil, or for reducing or eliminating existing solid precipitates/deposits contained in a flowing fluid, is provided. A fluid conditioning system and method are provided, along with a magnetic fluid conditioner that provides numerous magnetic field transitions through a magnetic flux density in the flow path of the fluid to reduce the formation of precipitates/deposits. A recirculating system using the invention may be set up to reduce deposits, such as paraffin in oil, by circulating oil through a pump, a magnetic fluid conditioner, a tank, and, in one embodiment, and a heater until the deposits/precipitates have been transitioned from a solid to a liquid. A multi-pole magnet, such as an eight-pole magnet, may be used in an embodiment of the present invention to increase the effectiveness of the present invention.

Embodiments of a gas diffuser plate for distributing gas in a processing chamber are provided. The gas distribution plate includes a diffuser plate having an upstream side and a downstream side, and a plurality of gas passages passing between the upstream and downstream sides of the diffuser plate. The gas passages include hollow cathode cavities at the downstream side to enhance plasma ionization. The depths, the diameters, the surface area and density of hollow cathode cavities of the gas passages that extend to the downstream end can be gradually increased from the center to the edge of the diffuser plate to improve the film thickness and property uniformity across the substrate. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can be created by bending the diffuser plate toward downstream side, followed by machining out the convex downstream side. Bending the diffuser plate can be accomplished by a thermal process or a vacuum process. The increasing diameters, depths and surface areas from the center to the edge of the diffuser plate can also be created computer numerically controlled machining. Diffuser plates with gradually increasing diameters, depths and surface areas of the hollow cathode cavities from the center to the edge of the diffuser plate have been shown to produce improved uniformities of film thickness and film properties.
