This invention is an apparatus for ophthalmic surgery comprising a laser source (52) that generates a laser beam (54); a scanner (56) comprising an input for said laser beam, and an output of a spatially scanned laser beam (54); controlling circuitry that drives said scanner (56) to remove tissue in a desired pattern on the eye (40); a microscope (58) for viewing said tissue removal; and a beam combiner (70) comprising a first input for a line of sight of said microscope (58) and second input for said spatially scanned beam (54).

The invention relates to a method and a system (10) for forming pressed articles by pressing powder or granules, the system comprising the following apparatuses: a powder discharge assembly (12); a no-cavity press assembly (20) including: an bottom plate (22) that is the same size or greater than the pressed articles, a constraining means to isolate a portion of powder, and a top punch (24); and a conveyor (14) to transport the powder and / or pressed articles.

A method is provided which includes dispensing a deposition solution at a plurality of locations extending different distances from a center of a microelectronic topography each at different moments in time during an electroless plating process. An electroless plating apparatus used for the method includes a substrate holder, a moveable dispense arm, and a storage medium comprising program instructions executable by a processor for positioning the moveable dispense arm. Another method and accompanying electroless deposition chamber are configured to introduce a gas into an electroless plating chamber above a plate which is suspended above a microelectronic topography and distribute the gas to regions extending above one or more discrete portions of the microelectronic topography. An exemplary microelectronic topography resulting from the aforementioned methods and apparatuses includes a layer having distinct regions each including a comparatively different thickness and comparatively different concentrations of one of the one or more elements.

The invention discloses a heat-insulating and noise-reducing nonwoven composite material for automobile interior trim and a preparation method thereof. The composite material is prepared from certain proportions of PP (polypropylene) fiber, PET (polyester) fiber and hollow PET fiber, the mixed fiber is prepared into a composite felt by a certain acupuncture process, and an appropriate die pressing process is adopted to prepare a composite fiber felt. The composite material disclosed by the invention keeps lower surface density, good bending performance and good dimensional stability, can also meet the functional requirements for heat insulation and sound insulation, and can be used for preparing medium and high-grade automobile interior trim materials.

The present invention comprises a method for forming an ultra-thin channel MOSFET and the ultra-thin channel MOSFET produced therefrom. Specifically, the method comprises providing an SOI substrate having a buried insulating layer underlying an SOI layer; forming a pad stack atop the SOI layer; forming a block mask having a channel via atop the pad stack; providing a localized oxide region in the SOI layer on top of the buried insulating layer thereby thinning a portion of the SOI layer, the localized oxide region being self-aligned with the channel via; forming a gate in the channel via; removing at least the block mask; and forming source / drain extensions in the SOI layer abutting the thinned portion of the SOI layer. Providing the localized oxide region further comprises implanting oxygen dopant through the channel via into a portion of the SOI layer; and annealing the dopant to create the localized oxide region.

The invention relates to a method for applying a porous glass layer. It is proposed to apply a porous glass layer by means of a PVD method. Porosity factor and average pore size can be varied by means of the process parameters such as pressure and deposition rate, as well as by deliberate addition of extrinsic substances.

The invention relates to a knitting method for a warp-knitted spacer fabric with different thicknesses. The warp-knitted spacer fabric is knitted by adopting six guide bars on a double-needle bar warp knitting machine, and the knitting method is characterized by comprising the following steps: (1) penetrating an upper surface layer yarn into guide bars GB1 and GB2, penetrating a lower surface layer yarn into guide bars GB5 and GB6, and penetrating a spacer yarn into guide bars GB3 and GB4, wherein the upper surface layer of the fabric is knitted by the guide bars GB1 and GB2, the lower surface layer of the fabric is knitted by the guide bars GB5 and GB6, and the spacer yarn is knitted by the guide bars GB3 and GB4; (2) when the thickness is changed in the transverse direction, penetrating the yarn by the guide bars GB3 and GB4 complementarily, wherein the yarn penetrating amounts of the guide bars GB3 and GB4 are equal, the guide bar GB3 penetrates the yarn first and then is spaced, and the guide bar GB4 is spaced first and then penetrates the yarn; the warp feeding amount of the guide bar GB3 is set to be smaller than that of the guide bar GB4; (3) when the thickness is changed in the longitudinal direction, setting the set warp feeding amount of part transverse area in the longitudinal row of the guide bar GB3 or the guide bar GB4 to be great, and setting the set warp feeding amount of part transverse area in the longitudinal row of the guide bar GB3 or the guide bar GB4 to be small. According to the knitting method for the warp-knitted spacer fabric with different thicknesses, the transverse cross section and the longitudinal cross section of the fabric can have different thicknesses by controlling the yarn penetrating amount and the warp feeding amount.
