Patent EP-0276968-A3 (EP)
IPC: G01N33/543
Filed: 1988-01-25
Abstract: A process for manufacturing a biograting 
for use in a light diffraction immunoassay is disclosed. 
The process comprises adhering a uniform layer of 
binding reagent on a smooth, solid surface and exposing the surface 
to UV radiation through a shadow mask with diffraction grating 
lines to selectively deactivate the binding reagent leaving a 
biological diffraction grating design of lines of active binding 
reagent. The method comprises applying the binding reagent to 
a surface selected from the group consisting of polysilicon and 
single crystalline silicon surfaces having on said surface, a 
biological diffraction grating design of lines of active binding 
reagent, and casting a precise focused shadow on the binding 
reagent layer without physically contacting the binding reagent 
layer with the shadow mask. With the biograting of this 
invention, the binding reagent is preferably chosen to bind 
selectively the organic analyte such as a microbe or fragment of a 
bacteria, virus, Mycoplasmatales, spore, parasite, yeast, enzyme, 
carbohydrate, antigenic protein such as an immunoglobulin, or 
organic compounds and substances having lower molecular weights.  
     A diffraction binding assay method for determining the presence 
or quantity of an analyte in an aqueous sample comprises contacting 
a diffraction binding assay surface with the sample for a time 
sufficient to permit conjugation of binding reagent and analyte, 
the diffraction binding assay surface being selected from the group 
consisting of polysilicon and single crystalline silicon surfaces 
having on said surface, a light disturbing design of substantially 
non-light disturbing binding reagent thereon, the binding reagent 
being selected to bind selectively with the analyte; separating the 
surface from the sample; and illuminating the diffraction binding 
assay surface with light from a light source, and determining the 
light diffracted by the diffraction binding assay surface.

Title: A force storage mechanism in an on-load tap changer
IPC: H01H9/00
Filed: 1989-08-23
Abstract: An operation frame (26) with two flanges (29, 30) and 
a drive frame (27) with a single flange (33) disposed 
between the two flanges (29, 30) are provided for forth and 
back movement, relative to a base frame (20), guided by a 
guide bar (24). Two coil spring elements (36, 37) are 
passed through by the guide bar (24) and are interposed 
between adjacent two of the flanges (29, 33; 30, 33). When 
the drive frame (27) is transferred to be deviated relative 
to the operation frame (26) held at a first operation 
point, one of the spring elements (36, 37) is compressed 
and the other (37, 36) tensioned. When the drive frame (27) 
is transferred to a prescribed position, the holding action 
on the operation frame (26) is released by a release piece 
(49) secured on the drive frame (27) and the operation 
frame (26) is swiftly transferred to a second position by 
the biasing forces stored in the spring elements (36, 37), 
operating a switch (5) in an on-load tap changer. If the 
drive frame (27) is actuated in the reverse direction on 
the next occasion, the operation frame (26) is transferred 
from the second to the first operation point similarly by 
the biasing forces stored in the spring elements (36, 37).

Title: Combined deemphasis circuit and noise blanker
IPC: H04H20/88
Filed: 1989-12-07
Abstract: An FM stereo radio circuit has an 
ultrasonic noise detector (66) and an amplitude noise 
detector (67) each for detecting impulse noise by 
developing an average noise signal and comparing the 
average noise signal with an attenuated value of the 
instantaneous noise signal to generate a noise flag. 
A dual mode circuit (62) normally operates as a low 
pass filter for a deemphasis function and is switched 
by the noise flag to operate as a sample and hold 
circuit which blanks the noise pulse. The dual mode 
circuit uses a switched capacitance design and is 
driven by clock signals to serve as a filter. The 
clock signals are stopped by the noise flag to effect 
the sample and hold function.

Title: Method for finding a preferred spot for a laser beam of a laser beam interferometer and laser interferometer apparatus
IPC: H01L21/302
Filed: 1989-07-11
Abstract: The disclosure relates to a method for endpoint detection in a semiconductor wafer etching ysstem characterised in the steps of: 1) scanning a semiconductor wafer (10) with a narrowly focussed laser beam (24); 2) analyzing a reflected portion of the beam to determine a preferred parking spot (P) on a preferred flat area (#8) of the wafer; 3) parking the beams at the preferred spot; and 4) analyzing the reflected portion of the beam to determine when the preferred flat area has been etched through. The beam spot (18) of the laser beam (24) is amller than the width of the preferred flat area to eliminate noise generated at the transition boundaries of the flat area. Preferably, the wafer is scanned several times along the same beam path to permit the comparison of several scans to determine the preferred parking spot. The apparatus includes a beam forming assembled (62, 64, 66); a scanning assembly which causes the laser beam to scan across the wafer; a detection assembly (76) responsive to a portion of the laser beam which is reflected off the wafer; and a controller (78) which operates the laser and the scanning assembly and which is responsive to an output of the detection assembly. When output of the detection assembly indicates a cessation of the characteristic etching curve, the controller develops an endpoint detection signal which can automatically shut down the etching system. <IMAGE>   <IMAGE>

Abstract: Bei der Übertragung hochfrequenter Signale über eine Leitung zu
einer integrierten Schaltung ist die Leitung möglichst nahe an
ihrem Ende angepaßt abzuschließen. Jedes Leitungsstück ohne
angepaßten Abschlußwiderstand und jede Leitungsverzweigung erzeugt
störende Reflexionen des Signals. Bei modernen Gehäusen
hochintegrierter Schaltungen haben die Anschlüsse nur noch einen
Abstand von 0,5 mm, und es wird zunehmend schwieriger, die
Signalleitungen möglichst dicht am Anschluß der integrierten
Schaltung mit einem Widerstand zu beschalten. Erfindungsgemäß wird
ein als Abschlußwiderstand wirkender Feldeffekttransistor (T R )
innerhalb der integrierten Schaltung angeordnet. Der durch den
Kanalwiderstand bestimmte Widerstandswert wird durch eine geregelte
Steuerspannung so eingestellt, daß Einflüsse der
Betriebstemperatur, Änderungen der Vorsorgungsspannung und
herstellungsprozeßbedingte Abweichungen der integrierten Schaltung
keine Auswirkungen auf den für die Leitungsanpassung erforderlichen
Widerstandswert haben.

Abstract: A method for generating, in a switching power supply, an
output voltage from an input voltage (302). The method
includes the step of closing a switch (304) in the
switching power supply to permit current from the input
source to flow through the inductor (310) and the capacitor
(312) of the switching power supply, thereby building up an
inductor current (I LX ) through the inductor (310) and
increasing the output voltage across the capacitor (312).
If a combination of the output voltage and inductor current
(I LX ) is satisfactory at the start of an off-time of the
oscillator signal (400), the method opens the switch (304).
If a combination of the output voltage and inductor current
(I LX ) is unsatisfactory at the start of an off-time of the
oscillator signal (400), the inventive method preferably
keeps the switch (304) closed past the off-time of the
oscillator signal (400) to continue building up the
inductor current (I LX ) through the inductor (310) and
increasing the output voltage across the capacitor (312).
