Abstract: The present disclosure relates to a CMOS image sensor having a multiple deep trench isolation (MDTI) structure, and an associated method of formation. In some embodiments, the image sensor comprises a boundary deep trench isolation (BDTI) structure disposed at boundary regions of a pixel region surrounding a photodiode. The BDTI structure has a ring shape from a top view and two columns surrounding the photodiode with the first depth from a cross-sectional view. A multiple deep trench isolation (MDTI) structure is disposed at inner regions of the pixel region overlying the photodiode, the MDTI structure extending from the back-side of the substrate to a second depth within the substrate smaller than the first depth. The MDTI structure has three columns with the second depth between the two columns of the BDTI structure from the cross-sectional view. The MDTI structure is a continuous integral unit having a ring shape.

Abstract: The present invention provides an improved electric fan structure, in which an electric fan is structured from an air converging vent; a main body and a base. The air converging vent comprises a plurality of guide strips, which are used to concentrate the air at an upper portion of the main body, and the bevel angled guide strips guide the air draft into the main body. The air is made to form a powerful vortex by means of a pass through type wind wheel formed as an integrated body in conjunction with a drive device causing the wind wheel to rotate, after which an induced draft plate covering a periphery of the wind wheel sends the air to an air outlet, where the air is blow out, thereby achieving functionality to realize optimum air volume output, and, at the same time, reduce noise when the electric fan is rotating.

Abstract: A method of converting organic waste to a useful end product by aerobic thermophilic fermentation process within a short period of time, includes the steps of mixing the organic waste that naturally contains microorganisms with the porous material as a fermentation medium in a mixing digester to form a waste mixture, providing an external heat source to transfer heat into the waste mixture of the organic waste and the porous material, maintaining the waste mixture at a thermophilic temperature to create microbial symbiosis and mutualism reaction to proliferate and grow beneficial thermophilic microorganisms between the porous material and microorganisms that naturally present in the organic waste and allowing whereby the microbial reaction to accelerate the organic waste fermentation and decomposition speed and decompose the organic waste into the usefil end product within a short period of time.

Abstract: A light emitting diode display which may be in the form of an array, dot matrix or number-shaped segments is obtained as follows. First, many lenses are formed by ejection at one time. This keeps the lenses at a definite interval from each other. Then continuous punching and cutting, as well as pressing and encasing, are used, to align the lenses and encase the same into prearranged holes on the display. A reflector is also encased to hold and clamp all the lenses between the display and the reflector. Finally, a circuit board welded with light emitting chips is encased and firmly fixed together with the display.
