摘要:
A polishing apparatus (100) is provided for polishing a substrate (102) that has slurry distributor (125) which improves planarization uniformity. Generally, apparatus (100) includes: (i) platen (106) with polishing surface (110); (ii) head (116) adapted to hold substrate (102) against polishing surface; (iii) mechanism to rotate platen (106) during polishing; (iv) dispenser (124) having nozzles (126, 128) to dispense slurry on the surface (110); and (v) distributor (125) between the nozzles (126, 128) and head (116). In one embodiment, apparatus (100) further includes a wiper (180) between head (116) and distributor (125) to remove used slurry and polishing byproducts from surface (110), thereby reducing agglomerations or deposits that can damage substrate (102) and improving yield. Optionally, apparatus (100) further includes dispenser (186) for dispensing a fluid before and/or after wiper (180) to substantially eliminate buildup of deposits. Method for polishing and substrate polished according to method.

摘要:
FIG. 1 is a top perspective view of a bed vacuum cleaner, showing my new design; FIG. 2 is a bottom perspective view thereof; FIG. 3 is a front view thereof; FIG. 4 is a rear view thereof; FIG. 5 is a left side view thereof; FIG. 6 is a right side view thereof; FIG. 7 is a top view thereof; and, FIG. 8 is a bottom view thereof. It is mainly composed of HEPA Filter, high-frequency tapping, vacuum motor, and visual trash can. It combines three functions of purple light, polaroid and vacuuming to absorb particles such as hair, pollen, dust, dander, etc. it is suitable for cleaning beds, sofas and other fabric products. The broken lines in the drawings illustrate the portions of the bed vacuum cleaner, which form no part of the claimed design.
摘要:
The invention provides methods of reducing fouling of ultrafiltration membranes in processes wherein virus particles are removed from aqueous solutions comprising virus particles and at least one protein by adding a surfactant or non-surfactant, non-ionic agent to the aqueous solution prior to filtration. The invention also provides methods to dissociate protein aggregates or to reduce the formation of protein aggregates by adding a surfactant or non-surfactant, non-ionic agent to the protein solution.
摘要:
Energy storage devices having hybrid anodes can address at least the problems of active material consumption and anode passivation that can be characteristic of traditional batteries. The energy storage devices each have a cathode separated from the hybrid anode by a separator. The hybrid anode includes a carbon electrode connected to a metal electrode, thereby resulting in an equipotential between the carbon and metal electrodes.

摘要:
An electric all-dimensional numerical control injection molding machine is applicable to production of injection products with high precision and complex three-dimensional shapes. The machine comprises a machine base, a main board, four sets of electric mould guiding devices, a cross-shaped chute mould assembly, and an injection device assembly. The electric mould guiding devices are mounted on a front face of the machine. A slider mould is disposed in a chute of a cross-shaped mould base, is connected to a shaft of an electric driver, and implements mould opening and closing functions by means of linear movement of the shaft of the electric driver. An injection system of the machine is used for injecting plasticized, fused, and homogenized plastic materials into a mould cavity of the mould.
