摘要:
A truck for pulling a semi-trailer includes an operator cab positioned on a frame and a fifth wheel mounted on the frame for receiving an underside of the semi-trailer. The trailer when attached to the truck defines a gap between a forward most portion of the semi-trailer and rearward most portion of the operator cab. A fairing can be located on the frame, aft of the operator cab and forward of at least a portion of the fifth wheel. The fairing can block at least a portion of the air flow attempting to enter the gap from below the frame.

A truck includes a frame, an operator cab on the frame and a drive axle having a differential. The differential can be connected to a drive shaft. A fairing for directing air flow around the differential is attached to the frame forward of the drive axle and forward of the differential. The fairing can have a non-deflected position and a deflected position.

The present invention provides a scanning transmission electron microscope (STEM). In the STEM, a specimen is sandwiched between a variable axis objective lens and a variable axis collection lens. The axis of the collection lens varies along with the variation of the objective lens axis in a coordinated manner. The STEM of the invention exhibits technical merits such as large scanning field, high image resolution across the entire scanning field, and high throughput, among others.

The methods of the invention provide improved rice grain nutrition by manipulation of the rice starch crystalline structure leading to easier penetration of nutrients into the rice grain and enhancement of rice grains with nutrients, thereby creating enhanced rice grain products. In addition, methods of direct delivery of nutrients into rice grains are also presented.

摘要:
An assembly for a charged particle detection device of high detection efficiency is described. The assembly comprising a metal grid for applying attractive potential to lure charged particles; a scintillator disc to absorb the energy from impinging charged particle and reemit the energy in form of light or photons; a light guide to transmit light or photons; and a photomultiplier tube (PMT) cohere with the end of light guide to receive light or photons from light guide and convert it into current signal. A light guide with a bullet-head-shaped front portion ensures total reflection of light propagating within the light guide. A frustum-cone-shaped scintillator disc releases the light that originally trapped in the scintillator disc due to the shape of scintillator.

Methods for fabricating gate electrode/high-k dielectric gate structures having an improved resistance to the growth of silicon dioxide (oxide) at the dielectric/silicon-based substrate interface. In an embodiment, a method of forming a transistor gate structure comprises: incorporating nitrogen into a silicon-based substrate proximate a surface of the substrate; depositing a high-k gate dielectric across the silicon-based substrate; and depositing a gate electrode across the high-k dielectric to form the gate structure. In one embodiment, the gate electrode comprises titanium nitride rich in titanium for inhibiting diffusion of oxygen.

The present invention discloses a method of manufacturing a fin field effect transistor, which comprises the steps of forming a plurality of first fin structures on a substrate, which extend along a first direction parallel to the substrate; forming a plurality of second fin structures on a substrate, which extend along a second direction parallel to the substrate and the second direction intersecting with the first direction; selectively removing a part of the second fin structures to form a plurality of gate lines; and selectively removing a part of the first fin structures to form a plurality of substrate lines. In the method of manufacturing a fin field effect transistor according to the present invention, the gate lines and substrate lines are formed simultaneously by first making uniform silicon wing lines and gate wing lines using a limiting photolithography patternizing technique and then performing a centralized cutting of the corresponding specific regions, thereby increasing uniformity and reducing process difficulty and cost.
