A two-step high density plasma-CVD process is described wherein the argon content in the film is controlled by using two different argon concentrations in the argon / silane / oxygen gas mixture used for generating the high density plasma. The first step deposition uses high argon concentration and low sputter etch-to-deposition (E / D) ratio. High E / D ratio maintains the gap openings without necking. In the second step, a lower argon concentration and lower E / D ratio are used. Since observed metal defects are caused by argon diffusion in the top 200-300 nm of the HDP-CVD film, by controlling argon concentration in the top part of the film (i.e. second step deposition) to a low value, a reduced number of metal defects are achieved.

A concrete block mold division plate for front-face-up block molding. The division plate fits into a channel formed in each of the side walls of the mold. A plurality of fasteners secure the division plate within each channel and to the side walls of the mold. The division plate operates in conjunction with an optimized dry cast concrete mixture to provide acceptable control of the flatness and parallelism of the top and bottom surfaces of the blocks.

A composition forming a rubber roller and an imaging apparatus including the rubber roller are provided by the invention. A small amount of a nitrogen-containing compound is formed during the process of preparing the rubber roller without deterioration of image quality of images produced by an imaging apparatus. The roller rubber forming composition includes a base rubber; a vulcanizing agent; a vulcanizing accelerator; a conducting agent; and one of an acid anhydride, a zeolite, and a blend thereof.

The present disclosure relates, according to some embodiments, to apparatus, systems, and / or methods for fractionating a feed mixture comprising, for example, one or more isocyanates, light components, solvents and / or heavier components. In some embodiments, fractionating an isocyanate feed mixture may comprise distilling the feed mixture in a non-adiabatic fractionating apparatus comprising a prefractionating section and / or column and a main section and / or column, which comprises a rectification section, a side section, and a stripping section. For example, isocyanates may be separated from light component(s), solvent(s) and / or heavier component(s). A fractionating apparatus may be configured and arranged, in some embodiments, as a dividing wall column. According to some embodiments of the disclosure, apparatus, systems, and / or methods may be energy efficient and / or may have a broad operating range.

A rare earth permanent magnet material is prepared by covering a sintered magnet body of R1—Fe—B composition wherein R1 is a rare earth element, with a powder comprising at least 30% by weight of an alloy of R2aTbMcAdHe wherein R2 is a rare earth element, T is Fe and / or Co, and M is Al, Cu or the like, and having an average particle size up to 100 μm, and heat treating the powder-covered magnet body at a suitable temperature, for causing R2, T, M and A in the powder to be absorbed in the magnet body.
