A process of producing a kaolin product for paper coating includes mining kaolin ores by hydromechanization and then producing kaolin slurry; classifying by centrifugal sedimentation; chemical bleaching; eliminating iron ions by circular rinsing; removing water by pressure filtration; producing slurry by dispersing filter cakes, in which complex dispersants, pH adjustor and intercalator are added; delaminating; classifying by vibrating sieve; and spray drying: spray driers are restructured by adding insulating layers on packing auger, elevator scoop and bunker at first; the kaolin slurry J which has passed through vibrating sieves is dried in high speed centrifugal spray drying tower and the moisture of kaolin powder is controlled in 3 wt. %-5 wt. %, and the kaolin product for paper coating is obtained. The process characterizes in stable properties, high efficiency, and high viscosity content and fine particle size of the kaolin products produced.

A pillar to rocker joint assembly comprising a tubular pillar having a pinched flange near a lower end of the pillar is joined to a rocker assembly including a side sill and rocker reinforcement. A method of making a pillar to rocker joint assembly that comprises a vehicle structural support is formed by welding a structural support pillar to an outer body panel through an access opening in the pillar and welding a rocker reinforcement to a side sill. The rocker reinforcement is welded to the pillar through an access opening in the side sill, an access hole in the body outer panel, and an access opening in the pillar that is vertically spaced relative to the first access opening. A bottom flange of the B-pillar is welded to a lower edge flange of the rocker reinforcement and a lower edge flange of the side sill.

A method for haze control on a semiconductor reticle, the method including performing a reticle inspection of a semiconductor reticle to detect haze formation on a periodic basis, performing a wafer inspection to detect haze defects, forecasting haze formation, and cleaning the semiconductor reticle. Also included is a haze forecasting method for haze control on a semiconductor reticle, including scanning a plurality of semiconductor wafers, identifying repeating defects in the semiconductor wafers, storing the repeating defects in a database as known repeating defects, and identifying an additional repeating defect that is not a known repeating defect, the additional repeating defect caused by semiconductor reticle haze.
摘要:
A support rail for a vehicle is disclosed that has an A-pillar portion and a roof rail portion. The roof rail and A-pillar are formed with a tubular body portion and longitudinally extending support flanges. The support flanges are formed by pinching the blank during the hydroforming process to provide a double thickness flange. A windshield support flange, roof support flange and door opening flange are formed to extend outwardly from the tubular body portion. Front and rear tube connectors may be provided that include blind openings or notches to facilitate welding.

摘要:
The present invention provides an apparatus of charged-particle beam e.g. an electron microscope comprising an in-column plasma generator for selectively cleaning BSE detector and BF/DF detector. In various embodiments, the plasma generator is located between a lower pole piece of objective lens and the BF/DF detectors, but outside trajectory area of the charged-particles from the sample stage to the BF/DF detector. Cleaning decomposed biological samples or contaminants on the surface of the detectors frequently and selectively with in-situ generated plasma can prevent the detectors from performance deterioration such as losing resolution and contrast in imaging at high levels of magnification.
摘要:
The present invention provides a driving system comprising two actuators for moving a stage through two elastic connectors; and a general apparatus/device comprising such a driving system, such as a machine tool, an analytical instrument, an optical microscope, and an apparatus of charged-particle beam such as electron microscope and an electron beam lithographical apparatus. When used in an electron microscope, the stage can be used as a specimen stage or a plate having apertures for electron beam to pass through. The novel stage driving system exhibits numerous technical merits such as simpler structure, better manufacturability, improved cost-effectiveness, and higher reliability, among others.
