Abstract: Reduction in energy consumption is had in a system for 
adsorptive removal of moisture and CO₂ from atmospheric air 
passing the feed air through consecutive beds of adsorbent

Title: Complementary lateral insulated gate rectifiers
IPC: H01L29/72
Filed: 1987-12-16
Abstract: A complementary Lateral Insulated Gate Rectifier (LIGR) includes two complementary LIGR structures fabricated in adjacent surface-adjoining semiconductor wells of the same conductivity type in a semiconductor substrate. The two LIGR structures are of generally similar configuration, thus simplifying the manufacturing process, and the proposed design additionally permits the n-channel and p-channel LIGR structures to have comparable "on" resitances. The two LIGR structures, otherwise isolated by a portion of the substrate separating the two semiconductor wells, are connected together by a common source electrode. The resulting complementary Lateral Insulated Gate Rectifier features a compact, integrated structure in which the "on" resistances of both the n-channel and p-channel portions of the device are comparable.

Title: Method and apparatus for controlling flow bias in a multiple zone process
IPC: F27B9/04
Filed: 1988-09-16
Abstract: The present invention provides a method and 
apparatus for controlling the fluid flow bias of 
continuous, multiple zone processes having gas or

physical or chemical property or a change thereof in 
at least one process atmosphere is monitored and an 
appropriate amount of force is applied in response 
to the monitored property. The monitored property 
is related to the furnace flow bias by an algorithm, 
so that the flow bias can be controlled by 
controlling the at least one chemical or physical 
property monitored.
