A method for manufacturing a magnetic read sensor at very narrow track widths. The method uses an amorphous carbon mask layer to pattern the sensor by ion milling, rather than a mask constructed of a material such as photoresist or DURIMIDE® which can bend over during ion milling at very narrow track widths. By using the amorphous carbon layer as the masking layer, the trackwidth can be very small, while avoiding this bending over of the mask that has been experienced with prior art methods. In addition, the track-width can be further reduced by using a reactive ion etching to further reduce the width of the amorphous carbon mask prior to patterning the sensor. The method also allows extraneous portions of the side insulation layer and hard bias layer to be removed above the sensor by a light CMP process.

Disclosed is a horizontal axis wind turbine of an downwind type having a rotor disposed downwind of a tower, comprising: a rotor having a hub and a blade; a nacelle to support the rotor rotatably through a main shaft connected to the hub; a cylindrical tower supporting to enable free yaw rotation of the nacelle; and an exhaust fan disposed on the nacelle, to exhaust an air inside the nacelle, wherein the cylindrical tower has a plurality of through-holes which are formed in a wall of the tower and scattered over an area of the wall along a circumferential direction thereof, to pass wind entering the rotor through the through-holes, and the exhaust fan is communicated with the through-holes through inner spaces of the tower and the nacelle, to generate aspiration force through the through-holes.

The invention relates to a method for reducing the interference of the ground and an isolation belt on an automobile millimeter wave radar. The method includes the following steps that: step 1, transmission signals are emitted, and return signals are generated when the transmission signals meet an object; step 2, the return signals are received; step 3, frequency mixing is performed on the returnsignals and local oscillation signals, so that intermediate-frequency signals can be outputted; step 4, distance fast Fourier transformation and Doppler fast Fourier transformation are separately performed on the intermediate-frequency signals; step 5, the distance-Doppler two-dimensional spectrum of the intermediate-frequency signals is obtained; step 6, distance dimension information and speed dimension information at a target position are extracted from the distance-Doppler two-dimensional spectrum, and the distance dimension information is subjected to constant false alarm processing by using a sorting method; step 7, a unit average method is adopted to perform constant false alarm processing on the speed dimension information which has been subjected to sorting method-based constant false alarm processing, so that the detection threshold value of the target position can be obtained; step 8, a final detection threshold value is obtained according to a set false alarm probability; step 9, the peak values of the target position are compared with the final detection threshold value; and step 10, whether a target object exists in the target position is judged.

An apparatus for and a method of operating an array of pixels of an image sensor, where each pixel includes at least a photosensor, an associated storage device and a floating diffusion region and the array of pixels is configured in a plurality of rows and columns. The photosensors associated with the pixels are reset and charges are accumulated in the photosensor. The accumulated charges are then globally transferred to storage devices associated with the pixels. A rolling double reset is used to reduce the deleterious effects on the accumulated charges stored in the storage devices. The accumulated charges stored in the storage devices are transferred to floating diffusion regions associated with the pixels and the charges residing in the floating diffusion region are read out. In a second embodiment the storage device is eliminated and the rolling double reset is used to reduce the deleterious effects on the accumulated charges stored in the floating diffusion region.

A multi-colored flocked article is provided having a plurality of flock and adhesive regions. Each flock region is defined by a plurality of flock fibers that are substantially the same in color and are substantially free of light dispersants, such as titanium dioxide. Further, each flock region is of a different color relative to an adjacent flock region to form a patterned, multi-colored design. Each of the plurality of adhesive regions corresponds to a flock region and includes a colored adhesive. The color of the adhesive is at least similar or substantially similar in color to the flock fibers in the corresponding flock region.

A system and method for capturing three-dimensional image data for inspection, alignment and operations of a material applicator includes an imaging system configured to capture three-dimensional image data of an electronic substrate. The imaging system includes one or more illumination assembly configured to project a spectrum of light substantially along a first axis at an angle to the surface of the electronic substrate. The imaging system further includes an image sensor assembly configured to detect the spectrum of light reflected from an electronic substrate surface, with the image sensor assembly including a viewing plane. The material application includes a controller that is coupled to the imaging system. The controller is configured to control movement of the imaging system and to communicate with the image sensor assembly to produce a three-dimensional image of the topology of the electronic substrate.
