    摘要: The present invention provides improved line and load regulation of a switching-mode power converter (300) without requiring additional capacitors (255), either internally or externally, to stabilize the control loop. The present invention can provide this by integrating a digital compensator (375) with the pulse-width modulator (“PWM”) of the switching-mode power converter. Such a compensator (375) can include comparators (310 and 330), digital circuits (340), and resistors (215, 220, 320, and 325).

    摘要: Molten ladle metallurgy furnace (LMF) slag is chilled on a chill plate comprising a number of steel slabs disposed side by side. The slag is poured onto the chill plate and allowed to solidify without the application of any water. Solid slag is removed from the chill plate by mechanical means and is eventually reused to make synthetic slag after further cooling, crushing and screening.

    摘要: Sensors that include SAW devices, related methods, and related devices. Many embodiments are included. Some of the present sensors include an inlet structure; a mounting structure that is spaced apart from the inlet structure, the mounting structure having a top surface and an opposing bottom surface; and surface acoustic wave (SAW) devices disposed on the top surface of the mounting structure; where (a) the mounting structure includes openings that extend from the top surface to the bottom surface through which fluid can flow that has first passed over the SAW devices during operation of the sensor, or (b) the mounting structure and SAW devices together define openings through which fluid can flow that has first passed over the SAW devices during operation of the sensor.
