Title: Saw filter and mobile telephone using same
IPC: H03H9/145
Filed: 1990-06-05
Abstract: A plurality of interdigital transducers (IDTs) (2.1-2.7; 4.1-4-6) of a 
surface acoustic wave bandpass filter (1), each of which has a 
plurality of electrode fingers arranged in a direction 
perpendicular to a propagating direction of surface acoustic 
wave, are connected alternatively to an input terminal (3) and 
an output terminal (5) of said filter. The IDTs are different in 
number of electrode fingers and in average value of inter-finger 
distance from each other and distance between 
adjacent IDTs are different. At least one of the outermost 
IDTs has a minimum number of electrode fingers and a maximum 
average value of inter-finger distance, compared with those

Title: Process for producing quality-improved water-absorbent polymers and products
IPC: C08J3/03
Filed: 1990-02-15
Abstract: This invention relates to a process for producing a 
quality-improved water-absorbent polymer in which the 
aqueous liquid ( I ), which is obtained by mixing in an 
aqueous medium at least one kind of a water-soluble salt ( A 
) selected from a group of halogenated compounds, sulfates, 
acetates, and nitrates, which are derived from at least one 
kind of a polyvalent metal selected from a group of 
aluminum, calcium, and magnesium, with at least one kind of 
a water-soluble salt ( B ) selected from a group of 
monovalent metal salts and ammonium salts, which are 
derived from at least one kind of an oxyacid selected from a 
group of sulfurous acid and thiosulfuric acid, is mixed 
with a water-absorbent polymer ( II ) in a proportion of 
that the water-soluble salt of the polyvalent metal ( A ) is 
in a range of 0.1 ∼ 10 parts by weight against 100 parts 
by weight of the water-absorbent polymer ( II ) and the 
water-soluble salt of the oxyacid ( B ) is in a range of 0.­
1 ∼ 10 parts by weight against 100 parts by weight of the 
water-absorbent polymer ( II ). The mixture which is 
obtained by mixing the aqueous liquid ( I ) with the water-­
absorbent polymer ( II ) has relatively-improved capacities 
 
 
in the fluidity and the amount of residual monomers. This 
invention displays a more sufficient effect by compulsorily 
bringing the mixture into contact with an oxygen-containing 
gas.

Abstract: A circuit for repairing a defective memory cell is 
provided between a row or column decoder and a memory cell 
array. When the decoder has n output lines, the memory 
cell array includes at least (n + 1) row or column lines, 
where n is an integer. The repair circuit includes 
connection circuit for connecting the output lines of the 
decoder to the row or column lines, and a circuit for 
defining the connection of the connection circuit. The 
connection circuit includes n switching elements each of 
which is operable to connect one output line of the 
decoder to at least two row or column lines. The defining 
circuit defines the connection path of each switching 
element such that the output lines of the decoder is

located row or column lines excluding a row or column line 
connecting a defective memory cell. The defining circuit 
includes a series of laser programmable fuse elements 
provided between an operation voltage supply and a ground 
line. The repair circuit occupies a reduced area of a 
chip because of no spare decoder and no program circuit 
and it carries out a reliable and fast memory repair 
because of the, reduced number of the fuse elements to be 
blown.

Title: Shell document with variable document commands
IPC: G06F17/24
Filed: 1990-03-13
Abstract: An improved technique for inserting variable text or 
images into shell documents (150) to produce complex 
reports and form letters. This technique greatly simpli­
fies the control structure used to insert the variable 
data and makes the maintenance and updating of shell 
documents much easier. To accomplish this, shell documents 
have common text (20, 24) and at least one variable docu­
ment command (152). Variable document commands are per­
mitted to have variable fields (154, 156, 158). In this 
way, variable text or images may be inserted based upon 
reference to variables stored in variable fields without 
the need to use conditional instructions in the shell 
document.

Title: A method for recovering a gaseous boron trifluoride and the use of the product formed in the method
IPC: B01J31/22
Filed: 1991-12-20
Abstract: The invention relates to a method for removing boron trifluoride from the exhaust gases of a vacuum pump, which gases have been obtained when polymerizing  alpha -olefines by using a BF3-alcohol complex as a catalyst.

Abstract: An orthogonal frequency division modulation (OFDM) method, is
provided in which a transmitter produces clock and a reference signal for
an accurate phase in modulation from a carrier, and a receiver reproduces
the reference signal having the accurate phase although a signal-to-noise
(S/N) ratio of the carrier is poor. The OFDM method includes the steps
of AM-modulating a group of a digital signal with a plurality of carriers, in
which a reference signal is FM-modulated at a symbol period, combining
the AM-modulated carrier and modulating the combined carrier into a main
carrier, detecting the main carrier by phase-locking the FM-modulated
reproduced reference signal with the transmitted reference signal and
fast-Fourier-transforming the combined carrier to demodulate the digital
signal.

foaming body having elastic property is used for the
semiconductive layer (27), and a diameter of foams in the
semiconductive layer (27) is controlled within the range of
between 200 µm and 400 µm. Alternatively, the average
micro-gap (which is obtained by equalization of a micro-gap
formed between the semiconductive layer (27) and the dielectric
layer) (28) may be controlled within the range of between 20 µm
and 50 µm. Consequently, a stable electrostatic attraction

unsatisfactory transfer of the toner image onto the
transfer paper (P) is prevented. The image forming apparatus
realizes an excellent image formation onto the transfer
paper, and the arrangement capable of reduction of the
