Abstract: The present disclosure provides an internally self-circulating fluidized bed gasifier and an air distributor therein for generating a stepped constrained wind. The air distributor includes a gas-material mixture through hole and a plurality of vent holes. Each of the vent holes is designed to have a winding path. Due to the winding paths of the vent holes and an arrangement of converging outlets of the vent holes to the gas-material mixture through hole, which is in communication with a furnace chamber, the present disclosure enables a gas entering the furnace chamber to form a stepped constrained wind and effectively prevents solid-phase materials in the furnace chamber from leaking into a gas mixture chamber. The internally self-circulating fluidized bed gasifier can achieve self-circulation combustion gasification for multiple times and a well-controlled gasification temperature, resulting in a high coal gasification efficiency without an ash leakage.

Abstract: The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable spectral filter layer is produced which defines apertures. Then, trenches are produced which extend through the clear encapsulation and establish sidewalls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches and producing aperture stops. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps.
