Abstract: A method is provided for forming a fully planarized trench isolated region in a semiconductor substrate for an integrated circuit, for example, a trench isolated field oxide region, or a trench isolated semiconductor region in which thin film semiconductor devices are formed.  Planarization is accomplished by a chemical mechanical polishing process in which coplanar layers of a chemical mechanical polish resistant material are provided in a centre region of wide trenches as well as on the semiconductor substrate surface adjacent the trenches.  The chemical mechanical polish resistant layer in the centre region of a wide trench forms an etch stop to prevent dishing of layers filling the trench during overall wafer planarization by chemical mechanical polishing.  The method is compatible with CMOS, Bipolar and Bipolar CMOS processes for submicron VLSI and ULSI integrated circuit structures.

Abstract: A hybrid former in a paper machine including a lower-wire loop in which there is an initial single-wire portion of a forming zone.          In this initial portion, there are draining elements inside the lower-wire loop and thereafter wire-guide and draining elements.          The former includes an upper-wire unit in which an upper wire is guided by guide rolls and by a breast roll onto a pulp layer formed on the single-wire portion of the lower wire.   In a subsequent twin-wire portion following the single-wire portion, there is a draining and forming unit which includes at least one pressure-loaded press unit and at least one draining-chamber and support unit, which units are arranged inside opposite wire loops. In the units, there are sets of ribs which are pressure-loaded against each other.  At the beginning of the twin-wire portion, inside the lower-wire loop, there is a revolving guide and forming roll which is in tangential contact with the lower wire or curves the twin-wire portion at a small angle which is in a range from about 0~ to about 5~.  The guide and forming roll is substantially immediately followed by the draining and forming unit which includes the sets of ribs.  In the area of the draining and forming unit, water is drained primarily through the upper wire while aided by the negative pressures in the draining chamber or chambers in the unit.
Patent CA-2149578-A1 (CA)
Title: Turbomachinery with variable angle fluid guiding devices
Inventor: HARADA HIDEOMI
IPC: F04D27/02
Filed: 1995-05-17
Abstract: A turbomachinery is presented to provide stable operation at fluid flow rates much lower than the design flow rate without introducing surge in the device.  This is achieved by providing a diffuser with variable angle vanes.        The vane angle at low flow rates is adjusted so as to minimize the diffuser loss of the exiting fluid stream from the impeller.  Since the flow angle of the exit flow of the impeller is a function only of the non-dimensional flow rates, and does not depend on the flow angle at the inlet the impeller, therefore, the vane angles can be regulated to achieve a stable operation of the impeller without producing surge of the turbomachinery at flow rates lower than the design flow rate.  To optimize the performance of the turbomachinery, in addition to the variable angle vanes, an inlet guide vane having variable vane angle is provided so that the turbomachinery can be operated at the required flow rate and head pressure.  The concept is demonstrated in a turbomachinery provided with variable diffuser vanes and an inlet guide vane.
