Title: Bipolar memory cell
IPC: H01L21/8229
Filed: 1989-01-10
Abstract: A switched load bipolar memory diode cell comprises first and 
second multi-emitter NPN transistors (72, 82) having bases 
cross coupled to the other's collectors in latch fashion. A PN 
diode (210, 200) is provided for each multi-emitter transistor 
(72, 82) having an anode coupled to a select line (102) through 
a load resistor (116, 100) and a cathode coupled to the 
collector of the associated multi-emitter transistor (72, 82). 
A parasitic lateral PNP transistor (104, 94) associated with 
the PN diode (210, 200) is provided for each multi-emitter 
transistor (72, 82) having an emitter coupled to the select 
line (102) through the associated load resistor (116, 100) and 
a collector connected to the base of the associated 
multi-emitter transistor (72, 82). In the standby mode, with 
only standby current flowing in either emitter, the product of 
the betas of the emitters of each multi-emitter transistor is 
much more than 1. Therefore, with low standby current, the 
cell acts just like a PNP loaded cell, but when the cell is 
being sensed, the cell effectively becomes a resistor with 
diode loaded cell.

Filed: 1989-04-24
Abstract: An active noise control system for controlling noise 
propagated through a duct (1) comprises a first microphone (5) located 
to receive the propagated noise at a point in a plane perpendicular to 
the length of the duct. A loudspeaker (6) is located substantially 
at that plane for introducing sound into the duct. An analog first 
control circuit (8,9,10,11) is operative in response to the noise 
received by the first microphone to feed a signal to the loudspeaker 
such that the sound introduced thereby destructively interferes with 
the noise at that point. A second microphone (13) is located 
further downstream to receive residual noise propagated along the duct 
despite the destructive interference. A second control circuit (14, 
15,16,17), responsive to the residual noise received by the second 
microphone, controls parameters of the analog first control circuit so 
as to minimise the residual noise. In particular,the first control 
circuit includes an integrator (9) which has a transfer function which 
is electrically controlled by the second control circuit.

Abstract: A branch device for use in an optical multiplex system
allows three stations to be interconnected by a relatively small
number of optical fibers. The branch device has WDM couplers
each having a port A connected to a port C through a through
path and to a port D through a cross path, and a port B connected
to the port C through a cross path and to the port D through
a through path. A signal light having a wavelength λ AB  in a
through-path wavelength band, inputted from a cable end A, is
transmitted through a through path in one of the WDM couplers
to a cable end B. A signal light having a wavelength λ AC  in a
cross-path wavelength band, inputted from the cable end A, is
transmitted through a cross path in the WDM coupler to the B
port thereof, and then transmitted through a cross path in
another WDM coupler to a cable end C. Similarly, signal lights
inputted from the other cable ends B, C are divided and
transmitted through paths depending on their wavelengths.
Stations can be connected to the branch device by transmission
cables each comprising a single pair of optical fibers for
bidirectional transmission of signal lights between the
stations through the branch device. A repeater on each of the
transmission cables may be of a single-system configuration for
upstream and downstream transmission.

Inventor: DEN BOER WILLEM
IPC: H01L21/336
Filed: 1996-05-15
Abstract: A liquid crystal display including an array of thin
film transistors. Each thin film device in the array
includes gate, source and drain electrodes. At least one
of the source and drain electrodes include first and
second metal layers offset with respect to one another so
as to reduce the channel length of the transistors.
Because of the reduced TFT channel length, the TFT
channel width can also be reduced while maintaining the
same ON current. Thus, the gate-source capacitance is
reduced which in turn reduces pixel flickering and image
retention and improves gray level uniformity. The first
and second source-drain metal layers are of different
materials so that the etchant for the second metal does
not etch the first metal layer deposited. The TFT may be
either a linear TFT or a ring-shaped TFT according to
different embodiments of this invention.

Abstract: An inflammatory cytokine is disclosed which has been isolated
from cells that have been incubated with a stimulator material.
The inflammatory cytokine comprises a protein that is capable of
binding to heparin, inducing localized inflammation characterized
by polymorphonuclear cell infiltration when administered
subcutaneously and inducing in vitro polymorphonuclear cell
chemokinesis, while lacking the ability to suppress the activity
of the anabolic enzyme lipoprotein lipase, cause the cytotoxicity
of cachectin/TNF-sensitive cells, stimulate the blastogenesis of
endotoxin-resistant C3H/HeJ thymocytes, or induce the production
of cachectin/TNF by primary thioglycollate-elicited mouse
macrophage cells. A particular inflammatory cytokine MIP-1 has
been isolated and has been found to comprise a peptide doublet
of similar molecular weights of about 8,000 daltons, and to show
a pI of about 4.6. The doublet has been resolved into its
component peptides, MIP-1α and MIP-1β for which distinct cDNA's
have been cloned and sequenced.
