Title: Matched quadrature coils for mri with minimized intercoil coupling
IPC: G01R33/36
Filed: 1987-02-09
Abstract: First and second co-located axially and circumferentially extending RF coils (10) are displaced spatially with respect to one another by 90 degrees so as to produce a pair of RF signals from the enclosed generally cylindrical volume which are in phase quadrature. Each of the coils includes four spaced-apart and generally parallel leg sections (L, to L<sub>4</sub>; L'<sub>1</sub> to L'<sub>4</sub>). The same coils (10) or one of them may also be utilized for transmitting NMR RF signals into the same volume. The coils have a common open-end through which objects to be imaged may be inserted and a common "closed" end for convenient location of RF coupling and feeding structures. Each of the coils (10) has an RF feedline structure (14, 16) which extends across a diameter of common closed end and the two feedline structures are disposed substantially perpendicular with respect to one another so as to minimize cross coupling. The feedlines are also spatially configured to faciliate mounting of associated tuning (Cp, C<sub>f</sub>) and coupling (C<sub>1</sub>, C<sub>2</sub>, C<sub>a</sub>, C<sub>b</sub>) capacitors. A fixed coupling "paddle" provides cancellation coupling between the coils and a movably mounted coupling paddle is arranged to provide variable amounts of cancellation coupling between the orthogonal feedline structures. The phase guadrature RF signals emanating from the pair of coils are preferably amplified before being combined in a 90° RF hybrid circuit.

Title: Conductive structures in polymers
IPC: H01B1/12
Filed: 1988-04-08
Abstract: Conductive structures in polymers are obtained by a method in which poly(organylheteroacetylenes) of formula I   <IMAGE>   or a mixture of poly(organylheteroacetylenes) of formula I and other polymers are exposed to radiation of high energy density, preferably laser radiation. At relatively low temperatures of 100 DEG  C. to 600 DEG C., the polymer structure is effected so that electrically conductive structures result. The products are employed in electrical engineering, electronics and microelectronics, preferably as printed conductors. The invention makes it possible to inscribe long-term stable, conductive structures in an insulating polymer matrix in a one-step method, it being possible to use modern computer techniques (computer graphics)and to produce computer-aided conductor structures directly. The polymers can be used without supports or applied on rigid or flexible materials.

Title: High speed parallel multiplier circuit
IPC: G06F7/508
Filed: 1988-11-21
Abstract: The binary multiplier circuit for obtaining a product of a 
M-bit multiplier and a N-bit multiplicand includes a multiplier 
circuit which produces a matrix of original summand bits having M 
rows and M+N columns and a matrix reduction circuit. In the ma­
trix reduction circuit, for every column of the matrix having 
three or more original summand bits, groups of three bits are 
input into full adder circuits which output a sum bit for that 
column and a carry bit for the column in the next most signifi­
cant bit position. For every column having three or fewer origi­
nal summand bits, and having the least significant column posi­
tion that is not yet reduced to two or fewer bits, groups of two 
bits are input into a half adder circuit which outputs a sum bit 
for that column and carry bit for a column in the next most sig­
nificant bit position. Iterative reductions are performed for 
each column by using full adder circuits for every group of three 
bits in a column and by using a half adder circuit for any re­
maining group of two bits in a column. The reduction continues 
until each column of the matrix is reduced to two or fewer bits. 
The remaining two rows of bits can be input to a carry-propaga­
ting adder circuit to output a sum equal to the product.

Title: Drive apparatus for liquid crystal display device
IPC: G09G3/36
Filed: 1988-12-29
Abstract: The invention relates to a drive apparatus for a 
liquid crystal display device. The voltage to be applied 
to longitudinally and latitudinally arranged liquid crystal 
cells of the liquid crystal display device is altered in 
polarity from field to field and from frame to frame, 
whereby the occurrence of flicker is prevented.  
     A field discriminating device counts the numbers 
of lines in first and second fields by synchronizing a 
vertical synchronizing signal at a leading point of time 
in a field time, whereby the difference in the number of 
lines between the first and second fields is detected, 
the field times being thereby discriminated.  
     When a video signal is erroneous, the field 
discriminating device provides a field discriminating 
signal, the level of which is changed alternately from 
field time to field time.

Abstract: A system and method for controlling an 
ignition timing for a vehicular internal combustion, are 
dislosed in which a basic ignition timing is determined 
on the basis of engine operating conditions, i.e., an 
engine revolution speed and pulsewidth of a fuel 
injection signal supplied to an injection valve for each 
engine cylinder. A first correction quantity to correct 
the basic ignition timing is determined on the basis of 
a change rate of the engine revolution speed. A second 
correction quantity to correct the basic ignition timing 
is determined on the basis of an engine load. A final 
ignition timing is determined on the basis of the basic 
ignition timing and/or first and second correction 
quantities when the engine falls into a transient 
operating condition, any one of shift gear positions is 
detected, the gear shift positions including a position 
in which no engine driving force is transmitted to a 
vehicular power train. The final ignition timing is 
determined according to the gear shift range postion. In 
addition, when the gear shift is placed in the position 
in which no engine driving force is transmitted to the 
power train and the change in the engine revolution 
speed occurs, the basic ignition timing is determined to 
be the final ignition timing.

Abstract: A method for forming an electrically conductive line 
between two layers of insulating material and method 
for connecting the line through both layers of the 
insulating material to the opposite surfaces is 
provided. In the method, first, second and third layers 
(10, 20, 28) of insulating material are provided 
wherein said first and third layers are separated by 
said second layer of insulating material which is 
different in etch rate from the first and third layers. 
The edge portion of all three layers is exposed and the 
insulating layer of the second material is selectively 
etched to remove the revealed edge portion and provide 
a slot (36) between the first (10) and third (28) 
layers of insulating material. Also openings (38) are 
provided in both the first and third layers of 
insulating material which communicate with the slot and 
extend respectively through the layers of the first and 
third insulating material. Thereafter, a conductive 
material such as tungsten is deposited in the slot and 
the openings and also on the face of the stacked 
insulating material. Finally, the excess tungsten is 
removed from the faces of the insulating material of 
the first and third layers leaving a conductive line 
sandwiched between the first and third insulating 
layers of the material; also metal remains in the 
openings formed to thereby form conductive studs 
extending from the line to the opposite surfaces of the 
insulating material sandwich so formed.
