Patent EP-0810478-A2 (EP)
Inventor: TALIEH HOMAYOUN
IPC: H01L21/027
Filed: 1997-05-22
Abstract: A coater (10) having a controllable pressurized process chamber (12) for applying photoresist to a wafer (9) is provided. The controllable pressurized process chamber (12) reduces the evaporation of solvent in the photoresist during a spin-on process step. Reducing premature curing of the photoresist results in improved uniform planarization of the photoresist layer. Contaminants in the photoresist are also reduced by having an environmentally controllable process chamber. A housing having a upper and lower section (11,19) forms a process chamber (12) surrounding a wafer chuck (13). The upper housing section includes a solvent vapor opening (22) for introducing pressurized solvent vapor into the process chamber and the lower housing section includes an exhaust opening (16a). The upper housing section also includes an opening (23) for introducing photoresist onto a wafer. A control device (30) is coupled to the exhaust opening and a vacuum device (38) for controlling the pressure in the process chamber. A sealed recycling photoresist container (31) and recycling apparatus (34) is also coupled to the exhaust opening to store unused photoresist. The unused photoresist may be used in subsequent spin-on process steps, thereby reducing processing costs.

Abstract: In a system for providing low cost data connections directly to a long
distance switch (240) in order to connect a plurality of ISDN-based data connections
to a data network such as the Internet (56) a line card (250) of this invention
connects directly to a time slot interchange unit (232) of a digital switch (240),
receives ISDN data and control information, extracts the control information and sets
up channels through to the data network (56), and provides ATM segmentation
reassembly and header routing information in both directions. This system also
provides policing and traffic shaping control for each ISDN connection and traffic
control so that a particular ISDN connection does not overload the resources of the
line card. The line card of this invention also provides ATM physical layer
processing SONET encapsulation, and SONET optical interfaces to a router on the
Internet. In this manner, numerous ISDN connections may be made inexpensively
by using fewer ISDN modems and channel banks, and lessen the load on local
switching systems.

Abstract: Described herein is a method for processing an input image including a plurality of input
pixels each having a first number of possible input levels of optical density to form an output image
including a plurality of separations each including a plurality of output pixels each having a second
number of possible output levels of optical density. The method includes the steps of generating a

corresponding pixels each being selected from one of the plurality of separations, modifying a
current one of the plurality of input pixels in a current one of the plurality of separations in
accordance with an error signal derived by processing previous ones of pixels in the current one of
the plurality of separations, generating a second threshold reference signal according to the output
levels of optical density of previously processed pixels in the current one of the plurality of
separations, and forming one of the output pixels by comparing the modified current one of the
plurality of input pixels to the generated first threshold reference signal and the generated second
threshold reference signal.

Title: Simplified interface to a TDM communications system
Inventor: PETTY NORMAN W
IPC: H04Q11/04
Filed: 1997-09-30
Abstract: A processor (100) that executes applications (99) which require
access to time slots of a time-division multiplexed (TDM) communications medium
(110) uses spare processing capacity and/or spare hardware of the processor to
interface to the TDM medium and to implement a time-slot interchange (TSI)
function in a simple and low-cost manner. The processor has a control store (104)
that stores a bit map of the time slots of the TDM medium. The bit
map is either examined by the processor during each time slot to determine,
or is used by external circuitry or spare internal circuitry of the
processor to generate interrupts or DMA requests that indicate to the processor
or to a host interface of the processor, which time slots to access. The
processor has a read buffer (105) and a write buffer (106) for effecting data
transfers between the TDM medium and the applications. The applications have
random access to the buffers, thereby effecting a time-slot-interchange function.

Abstract: A receiver system (12) automatically adaptively tunes
to broadcast signals that are variable in the number of channels
that are transmitted, their signal coding type and their modulation
format. A system receives (15) a digital bitstream representing
video information encoded in one of a plurality of different
formats, and transmitted on one of a plurality of transmission
channels. In the system, a method for acquiring data transmitted
on a transmission channel involves selecting (17) a transmission
channel from the plurality of channels and selecting (17) a
modulation format (25). The method also involves tuning (20) to
receive the modulation format and determining (50) whether
valid data is being received on the selected transmission channel.
The method steps are repeated until valid data is received. The
method may also involve selecting (17) a coding type (30,40), and
tuning to receive the coding type. In addition, the method of
acquiring data may involve capturing program guide information
and re-tuning to receive a transmission channel in response to the
program guide information.

indirect bilirubin reaction inhibitor selected from a
thiocyanate ion, a hydrazide, reduced nicotinamide
adenine dinucleotide, reduced nicotinamide adenine
dinucleotide phosphate and a potassium ion of 100 mM to
800 mM. By completely avoiding interference of indirect
bilirubin, direct bilirubin is selectively and precisely
determined using a reagent kit in the form of solution.
The method and reagent of the invention are safe and free

Abstract: In a control apparatus for use in an internal
combustion engine (8) which has an exhaust gas sensor
(20) adapted to detect exhaust gas components and provide
an output signal conforming to an air-fuel ratio of
mixture and which performs stratified charge combustion,
signals (A/F, IGN) for controlling the air-fuel ratio of
mixture and the fuel injection timing are generated on
the basis of the output of the exhaust gas sensor (20).
When an optimal air-fuel ratio responsible for combustion
stability is changed as a result of execution of EGR and
evaporative fuel purging, a change of the air-fuel ratio
is determined by using the output of the exhaust gas
sensor. When the influence of the EGR or the evaporative
fuel purging upon the air-fuel ratio is great, the air-fuel
ratio is corrected and the fuel injection timing or
the ignition timing is corrected.

Abstract: Electrical filter circuits 4 are tested by connecting
to the filter inputs without the need to connect to the
filter outputs or to disconnect the outputs from a load 5. A
signal generator 2 of known source resistance applies a.c.
signals successively over a range of frequencies to the
filter inputs, and a voltmeter 3 monitors the voltage across
the filter inputs. Different types of filter have different
characteristic shapes for the voltage/frequency curve, and
processing is applied to the measured results in a computer
to determine the location of inflections in the curve and
other characteristics of the curve. Methods are disclosed for
determining the values of the individual sub-components of
the filter. Where the filter is an L-C filter, an
interactive process is applied to successively improve the
accuracy of the component value determinations. Using the
techniques described enables the insertion loss of the filter
also to be readily calculated by the computer.
