Title: Improvements in barrier seal systems
IPC: F16J15/34
Filed: 1991-03-08
Abstract: This invention relates to barrier seal systems (10) for sealing the 
annular space between a housing (14) and a rotating shaft (12) which 
extends through a bore (16) in the housing (14). The seal system (10) 
has inboard (66) and outboard (46) mechanical end face seals. The 
inboard seal (66) faces have spiral grooves (98) for pumping a buffer 
fluid from a buffer chamber (68) between the two seals (46-66) toward 
the high pressure side of the inboard seal (66). The primary ring 
(76) of the inboard seal (66) may be double balanced. For high 
pressure applications, the buffer fluid may be pressurized and a 
pumping ring may be included in the outboard seal to circulate buffer 
fluid. High pressure applications also require two hard seal rings 
and optimum dam (100) and face widths. Buffer fluid can be supplied 
to the seal system by a reservoir (30) connected by a gravity feed 
line (108-112). A buffer fluid containment device may be attached to 
the high pressure side of the seal (10) to prevent process fluid from 
contaminating the seal faces or secondary seals.

Title: Method and circuit arrangement for determination of a control information for the quadrature phase in a qam receiver
IPC: H04L27/06
Filed: 1991-12-19
Abstract: 2.1 In a QAM receiver, a control information is to be generated by means of which the quadrature phase in the receiver can be very rapidly corrected with the least possible deviation to the quadrature phase of the respective received QAM signal value. 2.2 The parameter tuples Li = (ai, bi,  delta i,  epsilon i) belonging to every possible signal component pair ai and bi are determined. Then the deviation of each signal component pair (âi and @i) calculated from the associated parameter tuple Li are determined by threshold decision from the pair of received signal components (â and @) present in each case at the discriminator of the QAM receiver and in the case of a deviation lying below a predetermined threshold, a control information <IMAGE> is derived from the quadrature errors  delta i and  epsilon i of the parameter tuple leading to this slight deviation. <IMAGE>

Title: Contactless sheet resistance measurement method and apparatus
Inventor: VERKUIL ROGER LEONARD
IPC: G01R27/26
Filed: 1995-05-19
Abstract: The appts. comprises a device for establishing an amount of junction capacitance of the junction between the desired layer and the underlying substrate, and providing a signal indicative of the junction capacitance. A device generates a point location alternating current (AC) photovoltage between the desired layer and the underlying substrate. The photovoltage has a sinusoidal magnitude and frequency and is propagated radially outward from a point location along the desired layer by a resistive nature of the desired layer at an attenuation and phase shift. The generating device further provides a signal indicative of the AC sinusoidal frequency. A device monitors the attenuation and phase shift of the propagated AC photovoltage as a function of radial distance remote from the point location. The attenuation and phase shift monitoring device provides first and second output signals indicative of a first and a second monitored magnitude and phase at first and second radial distances, respectively. A device is responsive to the junction capacitance signal, the AC sinusoidal frequency signal, and the first and second attenuation and phase shift signals for generating an output signal indicative of a sheet resistance RS of the desired layer according to a prescribed sheet resistance model.

Abstract: A received signal is output to an echo path and, at the
same time, it is divided into a plurality of subbands to
generate subband received signals, which are applied to
estimated echo paths in the respective subbands to produce
echo replicas. The echo having propagated over the echo
path is divided into a plurality of subbands to generate
subband echoes, from which the corresponding echo replicas
are subtracted to produce misalignment signals. Based on

Abstract: In the present invention, a U-turn path G is
formed by facing an outer guide surface 2a of a guide
member 2 to an outer peripheral surface 1a of a convey
roller 1. A terminal edge 2A of the outer guide
surface 2a forming a part of an outlet Gb of the U-turn
path G is configured not to coincide with a straight
line but is tapered to be convex at a central portion.
When a thick sheet is conveyed through the U-turn path
G, a trail end of the thick sheet is shifted to the
terminal edge 2A while rubbing the outer guide surface
2a. Then, the trail end of the sheet leaves the
terminal edge 2A. Since the terminal edge 2A has the
tapered configuration, the trail end of the sheet is
gradually disengaged from the terminal edge, thereby
preventing the snapping restoring action of the trail
end to weaken shock.
