Title: Surface treating apparatus and method using vapor
IPC: H01L21/306
Filed: 1990-04-24
Abstract: A surface treating apparatus using vapor includes a 
container (1) for holding a mixture (2) of two liquids, 
e.g., hydrogen fluoride and water, which exhibits an 
azeotropic phenomenon under predetermined conditions, 
and an azeotropic condition establishing device (15) for 
conditioning the container (1) to satisfy the 
predetermined azeotropic conditions. Under the 
azeotropic conditions, a vapour mixture (3) having the 
composition of the liquid mixture is produced in the

IPC: H01L39/24
Filed: 1990-01-24
Abstract: Disclosed is a process for forming a 
superconducting film, in which multi-layer metal film 
(buffer film) is formed at a specific temperature on a 
ceramic substrate and a superconducting film is formed 
at a specific temperature on the multi-layer metal 
film. According to this process, a superconducting 
film having a high critical temperature can be formed 
over the ceramic substrate while controlling or 
suppressing the occurrence of a chemical reaction 
between the substrate and the superconducting film, and 
required superconducting performances can be 
manifested.
Patent EP-0384601-A3 (EP)
IPC: H05K5/03
Filed: 1990-02-05
Abstract: A conformable electromagnetic radiation 
suppression cover comprising one or more absorbing 
material(s) and a sealant. The cover conforms to the 
shape of a reflecting structure due to forces internal to 
the absorbing material(s) when the cover is subjected to 
an agent external to the cover. The absorber comprises 
dissipative particles bound in a conformable polymeric 
binder. The sealant is positioned to seal the conformed 
cover to the reflecting structure, and provides 
environmental protection to the structure and preferably 
better adhesion between the cover and the structure. In a 
preferred embodiment, the volume of the cover is varied 
before shrinkage to produce a cover thickness in the 
direction of incident radiation, as measured after 
shrinkage, which produces a preselected resonant frequency 
for the cover. The cover may include a conductive 
surface, such as a metallic foil. Impedance matching 
materials are preferred but not required.

Patent EP-0400833-A3 (EP)
Title: Transmit and receive diplexer for circular polarization
IPC: H01P1/165
Filed: 1990-05-14
Abstract: A diplexer for processing polarized energy at separate transmit and 
receive frequencies. The nature of the polarization may be circular, 
linear or elliptical, depending upon the phasing associated therewith. 
The diplexer comprises a waveguide having first and second ports (13,14) 
disposed at opposite ends thereof. A symmetrical bandpass resonator 
arrangement (15) is disposed around the periphery of the waveguide and 
couples energy at the receive frequency out of the waveguide. A 
symmetrical bandstop resonator arrangement (30,40) is also disposed 
around the periphery of the waveguide and filters energy at the receive 
frequency to prevent coupling of received energy to the second port. 
The bandpass resonators of each of the resonator arrangements generally 
include tuning members (23) that control the amount of energy 
coupled from the waveguide and that adjust and balance the polarization 
components of the energy to maintain the polarization state thereof. 
A plurality of tuning rings (50,51,52) may be disposed adjacent to the 
first port that compensate for the impedance mismatch caused by external 
components coupled to the waveguide. A tuning ring (53) may also 
be provided at the second port that compensates for impedance mismatch 
caused by the resonator arrangements. The diplexer is generally an 
overmoded structure that permits the propagation of higher order 
modes in the received energy. The symmetry provided in the bandpass 
resonator arrangement inhibits or prevents the excitation of these 
higher order modes and hence received energy not coupled out of the 
diplexer through the second port. Similarly, the symmetrical nature 
of the bandstop resonator arrangement also inhibits scattering of higher 
order modes and hence improves the performance of the diplexer.

Title: Method of implementing error corrected memory
IPC: G06F11/10
Filed: 1990-05-18
Abstract: A method of storing and retrieving a word (60) 
of digital information in a computer random access 
memory (124, 126) which includes generating a plurality 
of subwords (68, 69) from the word, storing the subwords 
in memory, reading the subwords from memory, and 
reconstructing the word from the subwords. Each 
generated subword (68, 69) contains a segment of digital 
information from the word (66, 67) and an error detec­
tion value capable of detecting an error in the subword. 
The generated subwords (68, 69) contain enough digital 
information to reconstruct the word at least once. Each 
generated subword is then stored in at least one 
location in memory (78, 79). A plurality of subwords 
containing enough digital information to reconstruct the 
word (60) are read from memory. The subwords so read 
are checked for errors. If a subword is found to 
contain an error, at least one replacement subword may 
be read from memory. The word of digital information is 
then reconstructed from the read subwords not containing 
an error.

Title: Interrupter switch with coordination of disconnect and interrupter linkage
IPC: H01H33/12
Filed: 1991-09-24
Abstract: An arrangement is provided that includes a coordinating input (e.g., via 62 to 64 to 54) for a mechanism (18) of an interrupter switch (10); the coordinating input being derived from sensed movement of an element (e.g., 32) away from a first position (FIGS. 3 and 4) and toward a second position (direction 67). The coordinating input is utilized to trip the interrupters if they are closed. In a specific arrangement, a stored-energy mechanism (18) is tripped to provide opening and closing of the interrupters via a high-speed interrupter drive train (20). The tripping arrangement (34) is operable via a first input (at 56 via 58,60) to cause movement of a latch member (40) to release the stored-energy mechanism (18) to operate the interrupter drive train (20). The first input may be actuated via open or close instructions, including both local and remote capabilities. The latch (40) for the stored-energy mechanism ( 18) is reset after each actuation. An output shaft (19) of the mechanism is connected to drive the interrupter drive train (20). Both opening and closing are accomplished via rotation of the output shaft (19) in the same direction. An open/close sensing input for the interrupter drive train (20) is derived from the position of the output shaft (19). In a specific embodiment, the sensed movement of the element (32) corresponds to the movement of a disconnect linkage (22) away from a closed position. <IMAGE>

diamond, a portion forming a head face consists 
essentially of high-purity diamond, and another portion 
supporting the head face consists essentially of low-purity 
diamond. The head face has high rigidity, while 
the portion supporting the head face has high toughness. 
In order to provide a bonding head portion which is mainly 
made of vapor-deposited diamond with electrical 
conductivity, a portion forming a head face consists 
essentially of polycrystalline diamond containing a 
relatively small amount of dopant, and another portion 
supporting this portion contains a large amount of dopant. 
The head portion having electrical conductivity can be 
heated by energization. In a tool employing a coating 
containing vapor-deposited diamond as a bonding head 
portion, the coating is formed by a complex of a metal or 
ceramics and vapor-deposited diamond, in order to improve 
strength of the coating and adhesion to a tool substrate. 
The metal or ceramics is closer in thermal expansion 
coefficient to the tool substrate than the diamond.
