Title: Manufacturing ccds in a conventional cmos process
Inventor: KOHLER EDWARD
IPC: H01L21/00
Filed: 2006-02-09
Abstract: A technique for forming Charge-Coupled Devices (CCDs) in a conventional Complementary Metal Oxide Semiconductor (CMOS) process. A number of single-layer polysilicon gates are formed on an as-grown, native doped silicon substrate, with gaps between them. Masking is used to selectively dope the gates while preventing doping of the silicon in the gaps. Masking may likewise be used to selectively silicide the gates while preventing suicide formation in the gaps. Conventional source-drain processing produces input/output diffusions for the CCD.

Inventor: BELONGIA PAUL
IPC: B65G69/22
Filed: 2007-12-07
Abstract: A dock leveler with a pivotal deck includes a stop mechanism that provides the deck with a positive stop at the deck's vertically stored position without the deck's actuator having to be fully extended. With the actuator being less than fully extended, the stop mechanism and actuator can exert opposing forces that help prevent the deck from rocking back and forth as the deck settles to its stationary, upright position. In some cases, the stop mechanism is part of a combination stop-and-lock mechanism that includes a locking device for temporary providing a redundant or alternate lock that prevents the deck from descending unexpectedly while the dock leveler is being serviced or repaired.

Abstract: Electrospray ionization sources interfaced to mass spectrometers have become widely used tools in analytical applications, Processes occurring in Electrospray (ES) ionization generally include the addition or removal of a charged species such as H+ or other cation to effect ionization of a sample species. Electrospray includes ionization processes that occur in the liquid and gas phase and in both phases ionization processes require a source or sink for such charged species Electrolyte species, that aid in oxidation or reduction reactions occurring in Electrospray ionization, are added to sample solutions in many analytical applications to increase the ion signal amplitude generated in Electrospray and detected by a mass spectrometer (MS). Electrolyte species that may be required to enhance an upstream sample preparation or separation process may be less compatible with the downstream ES processes and cause reduction in MS signal New Electrolytes have been found that increase positive and negative polarity analyte ion signal measured in ESMS analysis when compared with analyte ESMS signal achieved using more conventional electrolytes. The new electrolyte species increase ES MS signal when added directly to a sample solution or when added to a second solution flow in an Electrospray membrane probe, It has also been found that running the ES membrane probe with specific Electrolytes in the second solution of the ES membrane probe have been found to enhance ESMS signal compared to using the same electrolytes directly in the sample solution being Electrosprayed The new electrolytes can be added to a reagent ion source configured in a combination Atmospheric pressure ion source to improve ionization efficiency,
