Title: Apparatus for coating substrates
IPC: C23C14/56
Filed: 1988-04-22
Abstract: An apparatus for coating substrates in a vacuum chamber has a cathode system, which is preceded and followed by evacuable isolating chambers. The individual chambers can be separated from one another by locks, and the apparatus has a conduit leading into the coating chamber for feeding one or more process gases. Transport frames carry the substrates through the individual chambers on rails and/or wheels. In such an apparatus one or more bypass lines are provided which connect the coating chamber to the isolating chambers preceding or following it, and a shutoff or valve is inserted into each bypass line and brings about an equalization of pressure between the chambers. By means of a pressure equalization performed in this manner, the constancy of the gas concentrations which is essential in a reactive process to the stability of the process and to uniform coating properties, is automatically assured.

Patent EP-0315792-A3 (EP)
Title: Interconnection system for integrated circuit chips
IPC: H05K3/34
Filed: 1988-10-14
Abstract: A novel packaging system for VLSI circuits allows low-cost 
construction and maintenance of complex high density high-­
performance devices with low power requirements. The devices can 
be individually created by software means from a small selection of 
standardizable IC chips by disposing a plurality of chips in leadless 
chip carriers in a mosaic on a substrate, and configuring them by 
software to selectively communicate with other chips of the mosaic 
or even to individually change their operating function. The 
immediate juxtaposition of the chip carries in the mosaic eliminates 
transmission line data skew, and also allows considerable savings in 
chip space and power requirements by dispensing with 
interconnection drivers, receivers and bonding pads. The chip carrier 
mosaics may be assembled into modules suitable for plug-in 
connection to an interconnecting backplane to create even larger 
devices, and individual modules can be dynamically tested in their 
high-performance mode by configuring one or more modules as test 
modules and either plugging them into modules to be tested or 
making them a permanent part of the device's module array.
Patent EP-0317984-A3 (EP)
Title: Nonvolatile memory
IPC: H03K17/687
Filed: 1988-11-23
Abstract: In a nonvolatile memory of the present invention, 
a write circuit (10) is connected between bit lines 
(BL) and a write-enable voltage terminal (V pp ) and has 
at least two write MOS transistors (11, 12) connected 
to each other in a serial manner. Since at least two 
write MOS transistors (11, 12) are connected in a serial 
manner, a punch-through effect is reduced even if noises 
occur in a write voltage system. Even in the case where 
a punch-through effect occurs due to the presence of a 
power source and transistors (11, 12), a voltage on the 
bit line (BL) is reduced, thus preventing a write error 
from occurring relative to the memory cell transistors 
(MC).

Title: Dual rail processors with error checking on i/o reads
IPC: G06F11/16
Filed: 1988-09-05
Abstract: A dual processor data processing system having inter­
processor error checking includes a first central processing unit 
executing a series of instructions. A second central processing 
unit executes the same series of instructions independently of 
and in synchronism with the first central processing unit. 
A first data bus is coupled to the first central processing unit for 
receiving data to be input to the first central processing unit 
and a second data bus is coupled to the second central processing 
unit for receiving data to be input to the second central pro­
cessing unit. Error checking devices are coupled to the first 
and second data busses for checking data transmitted over the 
first and second data busses and for detecting errors on I/O 
reads prior to delivery of the data to the first and second cen­
tral processing units. The error checking devices include com­
parison means for indicating an error when the data on the first 
and second data busses are unequal. Error isolation devices are 
responsive to an error detected from the error checking means for 
analyzing the cause of error while maintaining system synchroni­
zation.

Patent EP-0354463-A3 (EP)
IPC: C23F4/00
Filed: 1989-08-02
Abstract: A dry etching method for refractory metal or its compound uses 
a mixed gas of an etchant gas for etching said refractory metal 
and a deposit gas for depositing said refractory metal. Halide 
of the etched refractory metal is used as the deposit gas. By 
using such a mixed gas, the refractory metal is etched at a 
portion where ion assist is strong, while the refractory metal 
is deposited at a portion where the ion assist is weak. In the 
dry etching, the ion (15) mostly hits the surface of the object 
facing against the anode (9) and hence the ion assist is 
strong, while the ion assist is weak at the side wall. 
Accordingly, the refractory metal is etched at the bottom 
surface (18) of an etched groove. but at the side wall of the 
groove the refractory metal is deposited. This deposited 
metal (19) protects the side wall from side etching. Therefore 
a fine pattern having a high aspect ratio etching is achieved.

Title: Reproduction and enlarging imaging system and method
IPC: B41J2/215
Filed: 1990-02-21
Abstract: A system for copying images onto a long sheet of paper (4) or vinyl 
while. A flow of constant-pressure air is pulse-width modulated in 
accordance with the control signals and passed over an ink meniscus 
maintained on the end of a small nozzle (38). The pulse-modulated air 
flowing across the meniscus causes the ink to be sprayed onto the 
recording medium. The dot size on the image remains constant and the 
pulse width within each pixel is varied to produce the desired density 
of color. Pressure surges in the ink supply system (34,36), produced for 
example by vibration or acceleration of the ink, are suppressed by a 
second meniscus (54) in the ink-supply system, formed by a gas bubble or 
interface near the nozzle meniscus. The second meniscus (54) should have 
a surface area at least as large as that of the jet meniscus. At the end 
of each pixel, the ink flow is interrupted for a period of about 100 
microseconds to restore system equilibrium. A second and continuous 
air flow around the air nozzle (42) supplies air to the turbulent flow 
across the ink jet and reduces recirculation of atomized ink (44) and 
minimizes contamination of the nozzle (38) and adjacent surfaces. The 
supply roll (2) is mounted at each end on independently movable 
arms (102,102a).
