摘要:
The present invention utilizes a high-speed intensive mixer in a fluidizing-type, solid-phase, neutralization reactor to blend solid-state alkali hydroxide with any humic acid sources. The final product is a dry humic acid salt. The purpose of this innovative method is to eliminate a series of complicated unit operations commonly employed by the traditional process. These removed steps may include dissolving caustic soda, mixing in a paste-like formation, extrusion, granulation, drying, and grinding, etc. The invention contributes to a simplified flowsheet, resulting in sharply reduced equipment investment, plant space, and labor and energy costs. All of these factors coupled with increased productivity will drastically lower the overall production cost. Also, the reduction of dust pollution will greatly minimize the impact in environmental protection and safety issues.

A block ring for a tube assembly for a reverse osmosis filter cartridge has multiple block segments connected to each other into a loop; any two adjacent ones of the block segments pivotally connected to each other, and outer ends of two of the block segments detachably abutting each other. For assembling, the block ring that is not formed into a loop yet is mounted into an outer annular groove of a tube body, and then the two block segments are rotated to make the outer ends abut each other. Thus, the block segments are braced transversely to securely abut the outer annular groove. Therefore, the block ring is securely mounted in the tube body. Besides, the block ring is integrated axially, such that the block ring can effectively and axially bear the outward abutting of a bearing plate, which prevents the block ring from deformation and enhances the safety.

A power supply is coupled to an input voltage source. The power supply includes a plurality of converters. Each converter has an input for receiving an input voltage and an output for providing an output voltage. The inputs are connected in series and the outputs are connected in parallel to provide an output voltage. The power supply further includes an output regulating controller coupled to one of the plurality of converters for regulating the output voltage. The power supply further includes one or more input regulating controllers correspondingly coupled to the remaining one or more converters of the plurality of converters for regulating one or more input voltages.

A power controller has a high-side driver, a low-side driver, a voltage divider, and a comparator. The high-side driver drives a high-side power switch, powered by a boost power line and a connection node. The low-side driver drives a low-side power switch, powered by an operation power line and a ground power line. The voltage divider has a first resistor having a first node for providing a detection voltage and a second node coupled to the boost power line or the connection node. The voltage divider has a second resistor coupled between the first node of the first resistor and the ground power line. When the low-side power switch is turned off, the comparator compares the detection voltage with a reference voltage. When the detection voltage is higher than the reference voltage, the comparator renders to turn on the high-side power switch.

A container includes a receptacle, a stationary base, a rotating device, a power supply device, and an actuator. The receptacle receives a substance therein. The rotating device and the power supply device are arranged in the stationary base. The stationary base includes at least one light-emitting element. The rotating device drives the receptacle to rotate. The power supply device is electrically connected to the light-emitting element. The actuator extends into the stationary base and is reciprocally movable. The movement of the actuator drives the rotating device and actuates the power supply device. When a user pushes the actuator to cause the receptacle to rotate for providing effects of stirring and reducing temperature of the substance (such as liquid) received in the receptacle, the light-emitting element of the stationary base is also caused to generate and emit light to thereby achieve the advantages of enhancing interest, decoration, aesthetics, and practical utilization.

An apparatus for wafer edge exposure comprises a first exposure unit and a second exposure unit. The first exposure unit includes a first light source to emit first light of multiple wavelengths, and a first mask to direct the first light toward a first area at an edge portion of a wafer. The second exposure unit includes a second light source to emit second light of a single wavelength, and a second mask to direct the second light toward a second area at the edge portion of the wafer. The second area encloses a transition area that borders the first area under the first mask.
