Title: A method of producing plastic tanks for washing machines and a tank thus obtained
IPC: D06F37/26
Filed: 1989-11-24
Abstract: A method of producing plastic tanks for washing machines, comprising a 
rigid structure (5) formed by the peripheral cylindrical band (6) and the 
circular bottom wall (7), and a separately realized circular front wall (8), 
and comprising a plurality of hollow radial arms (11) integral with the 
bottom wall (7) and adapted to contain air or gas.  
     The method comprises a first phase in which the plastic material is 
injected into the mold for forming the tank in a quantity so as to 
occupy partially the inside cavity of the mold , and a second 
phase in which air or gas is blown into the plastic material in such a 
way as to swell the mass and fill the entire cavity of the die, and 
also form the inside cavities (13) in the radial arms (11) in which the air 
or gas remains enclosed.  
     Tanks of this type are structurally resistant and realized with a low­
er consumption of material.

Title: Storage-stable transdermal patch
IPC: A61M37/00
Filed: 1989-11-07
Abstract: A shelf-stable device for transdermally administering an 
active pharmaceutical to a patient. The device includes a drug 
reservoir (16) that contains the drug formulation. In one preferred 
embodiment of the present invention, 
the drug reservoir (16) is sandwiched 
between an upper (18) and a lower (20) 
solvent barrier film that are made from 
a material such as a polyester that will not absorb the drug and/or 
skin permeating enhancing solvent, if any, contained within the 
reservoir. The drug reservoir and solvent barrier films are 
encapsulated within a hermetically-sealed compartment (22) that protects 
the drug formulation from common environmental factors such as water 
vapor, oxygen, and light which can adversely affect the stability and 
efficacy of the drug formulation. The hermetically-sealed (22) 
compartment also prevents the drug formulation from coming into 
contact with and possibly dissolving the adhesive used to secure the 
device to the patient's skin. In another particularly preferred 
embodiment of the present invention, the device's drug reservoir is 
encapsulated within a hermetically-sealed compartment that is made 
from (combined) solvent/environment barrier 
films (70) that serve the dual functions 
of preventing the device's components from absorbing the drug/solvent 
formulation from the reservoir, and protecting the drug/solvent 
formulation from common environmental factors.

Filed: 1989-07-31
Abstract: A method for recording and reproducing a colour 
video signal having a luminance signal and two difference 
chroma signals together with a key signal by using two video 
tape recorders which are synchronously driven comprises the 
steps of dividing the two difference chroma signals so as to 
obtain high frequency components and low frequency 
components of the two difference chroma signals, recording a 
first video signal having the luminance signal and the two 
difference chroma signals having the low frequency 
components, and a second video signal having the key signal 
and the two difference chroma signals having the high 
frequency components in a format of 4:2:2 digital video 
signal processing by using a 4:2:2 type video tape recorder 
respectively, reproducing the first and second video 
signals, and combining the reproduced first and second video 
signals so as to obtain the colour video signal and the key 
signal. In a variant, the first and second video signals 
may be recorded on the same tape, with the second video 
signals being recorded in the guard bands between the tracks 
in which the first video signals are recorded.

Title: High power laser with focusing mirror sets
IPC: H01S3/08
Filed: 1989-11-29
Abstract: A laser system employs mirror sets (30, 31; 32, 33; 34, 35; 36, 
37, 38, 39; 40, 41; 42, 43) having substantially astigmatism-free 
focusing power sufficient to maintain a desired laser beam diameter, 
to compensate for thermally-induced distributed lensing. The system 
is a high power gas laser system having a folded optical cavity with 
the mirror sets acting as a periodic intracavity refocusing means to 
compensate for distributed negative thermal lensing in the hot 
plasma that comprises the active medium, and thus maintain a 
substantially constant beam diameter throughout the optical cavity. 
Each corner mirror set includes at least one curved mirror and at 
least one other mirror at each corner of the folded optical cavity. 
In one example, each corner mirror set is a spherical mirror (31) 
and cylindrical mirror (30). In another example, each corner mirror 
set comprises three nirrors (including three spherical mirrors, or 
two spherical mirrors and a planar mirror). In another preferred 
example, the focusing mirror sets are not included within the 
optical cavity of a high power laser, but instead, one or more such 
focusing mirror sets are included within the output beam delivery 
optical components of a high power laser. For example, one of the 
focusing mirror sets may replace a conventional lens to direct the 
output beam of a high power laser system along a desired path and 
maintain a desired beam diameter.

Title: Magnetic resonance imaging system
IPC: G01R33/561
Filed: 1989-11-29
Abstract: A magnetic resonance imaging system collects all 
the data required for image reconstruction of a prede­
termined portion of an object (5) under examination by 
one excitation process in accordance with a pulse 
sequence in which, after excitation of spins within the 
predetermined portion by a radio frequency magnetic 
field and a gradient magnetic field, a predetermined 
readout gradient magnetic field is applied switched 
positive and negative at high speed to produce multi­
echoes on both sides of a spin echo center and a prede­
termined phase encoding gradient magnetic field is 
applied whose amount and sequence in encode steps are 
controlled so that multiecho data or its complex conju­
gate data may scan substantially the half of a Fourier 
data plane. By taking the complex conjugate of the 
magnetic resonance data collected in that way and then 
two-dimensional Fourier transforming the magnetic reso­
nance data and the complex conjugate data, a magnetic 
resonance image of the predetermined portion of the 
object (5) is obtained.

IPC: F02D41/14
Filed: 1995-08-14
Abstract: A fuel metering control system for an internal
combustion engine, having a feedback loop. In the
system, the quantity of fuel injection (Tim) to be supplied
to the engine (plant) is determined outside of the feedback
loop. A feedback correction coefficient (KSTR) is calculated
using an adaptive controller and a feedback control is
carried out by multiplying the quantity of fuel injection by
the coefficient in the feedback control region. In view of
the situation, once leaving the feedback control region due
to, for example, fuel cutoff, but soon returning to the
feedback control region shortly, internal variables of the
adaptive controller necessary for coefficient calculation
are held so as to make it unnecessary to determine the
variables and to keep the control continuity and to enhance
the controllability. On the other hand, if it takes a
longer time to return the region, the variables are set to
initial values.
