摘要:
The present invention provides a two-piece capless fuel-filling device and method of attaching the same to a vehicle. The capless fuel-filling device includes two primary components, an exterior housing member and an interior housing member. The exterior housing member is first placed within an opening formed in a vehicle body panel and attached thereto. Next, the interior housing member is attached to the exterior housing member or the interior side of the body panel. Either the internal housing member or the external housing member includes a valve for enabling and restricting insertion of a refueling nozzle.

A pressure relief device for venting an internally pressurized container such as an aerosol can has three sections, a concave annular outer area, a circular central area and an annular intermediate area connecting the concave annular area to the circular area. The three sections all have the same thickness. The central area has a center point and an arc shaped score line extending through 132° to 138°, preferably 135°, about an arc center. The arc center is offset from the center point of the circular area by a distance of from about 0.290 inches. The score line has a depth of from 0.010 to 0.012 inches and is trapezoidal in transverse cross section. The intermediate area meets the circular area at an angle greater than 90° and the intermediate area meets the concave annular outer area at an angle greater than 90°.

This invention pertains to electronic/optoelectronic devices with reduced extended defects and to a method for making it. The device includes a substrate, a semiconductor active material deposited on said substrate, and electrical contacts. The semiconductor active material defines raised structures having atomically smooth surfaces. The method includes the steps of depositing a dielectric thin film mask material on a semiconductor substrate surface; patterning the mask material to form openings therein extending to the substrate surface; growing active material in the openings; removing the mask material to form the device with reduced extended defect density; and depositing electrical contacts on the device.

A method to electrolessly plate a CoWP alloy on copper in a reproducible manner that is effective for a manufacturable process. In the method, a seed layer of palladium (Pd) is deposited on the copper by an aqueous seeding solution of palladium acetate, acetic acid and chloride. Thereafter, a complexing solution is applied to remove any Pd ions which are adsorbed on surfaces other than the copper. Finally, a plating solution of cobalt (Co), tungsten (W) and phosphorous (P) is applied to the copper so as to deposit a layer of CoWP on the Pd seed and copper.

In one embodiment, this invention pertains to a process for making single crystal gallium nitride in the region of the phase diagram of gallium nitride where gallium nitride is thermodynamically stable. The process includes the steps of placing a charged reaction vessel into a chamber, the reaction vessel containing a gallium nitride source and a salt-based solvent in contact therewith; heating the charge in the reaction vessel to render the solvent molten and to provide a temperature gradient in the molten solvent between the gallium nitride source and the growing single crystal gallium nitride in such a way that growing the single crystal gallium nitride will be in the region of the reaction vessel which, under operating conditions, will have a temperature near the low end of the temperature gradient and the gallium nitride source will be in the region of the reaction vessel which, under operating conditions, will have temperature near the high end of the temperature gradient; maintaining process conditions whereby the solvent is molten, with the gallium nitride from the gallium nitride source dissolving in the solvent under the impetus of the temperature gradient; precipitating gallium nitride out of the solvent; and discontinuing the heating step.

An aqueous solution of local anesthetic is instilled into the urinary bladder in sufficient concentration with the addition of an alkalinizing agent such as sodium bicarbonate to elevate the intra-vesical pH to approximately 8.0. The combination is left in situ in the bladder for at least fifteen minutes to allow time for absorption of the base form of the local anesthetic. This method provides safe and effective topical anesthesia to allow pain-free cystoscopic biopsy and cautery of bladder lesions such as bladder cancer, and provides a means to treat inflammatory conditions of the bladder such as chronic interstitial cystitis and acute bacterial cystitis.
