Patent EP-0385548-A1 (EP)
Inventor: VAN VAALS JOHANNES JACOBUS
IPC: A61B5/055
Filed: 1990-02-26
Abstract: The method includes a critical time shift of a refocusing pulse between two (90 o ) excitation pulses which produce multiple quantum coherence signals and which are followed by a (90 o ) read pulse (using a critical timing a refocusing pulse serving the same purpose can also be applied between the second excitation pulse and the read pulse). With respect to the centre of the time path between the excitation pulses or between the excitation pulse and the read pulse the time shift is chosen to be such that given resonances do not occur positively or negatively in the spectrum whereas other resonances do occur therein (i.e. at substantially maximum strength). The MRI method can be combined with the use of spatially selective gradients in order to obtain localised spectra or images.

The keyboard is constructed employing a plurality of keys aligned in registration with the key switch portions (26), each key having a shorting bar (104) for causing electrical connection across the key switch portion when the key is depressed. The top case (13) of the apparatus has an aperture for viewing the display device and a plurality of apertures for the keys. The keyboard may alternatively be constructed of a flexible membrane (12) in which pressure on a key switch position (163) causes electrical contact with a conductive ink (153) disposed in a depression (152) in the case (150) of the apparatus. In an alternative embodiment, the top case also includes an aperture enabling light to shine on a photovoltic power cell (19) employed to generate the electric power needed to operate the apparatus.

Patent EP-0401174-A1 (EP)
Inventor: GUALANDRIS FABIO
IPC: H01L29/78
Filed: 1990-04-24
Abstract: A surface field effect integrated transistor has the sur­face of the silicon in the source and drain areas (4, 4', 7, 7') lowered by 50-500 nm in respect to the surface of the silicon (2) underneath the gate electrode (1) by etching the silicon substrate before forming the source and drain junctions. 
     The transistor is sturdy and reliable because of the backing-off of the multiplication zone of the charge carriers from the gate oxide by a distance greater than several times the mean free path of hot carriers, thus markedly reducing the number of hot carriers available for injection in the gate oxide. 
     The modified fabrication steps are readily integrable in a normal CMOS fabrication process.

Title: Low pressure recirculation valve.
Inventor: LOOS GEORGE
IPC: F16K17/04
Filed: 1990-05-21
Abstract: A low pressure recirculation valve for cooling a centrifugal pump. The invention comprises a unitary valve casing divided into a first valve chamber and a second valve chamber, the casing having a first port for introducing fluids into said first chamber, and a second port for expelling fluids out of said second chamber, the first chamber having a recirculation port for redirecting fluids back to said centrifugal pump. A multiple piece check valve member situated between said first chamber and second chambers permits the flow of fluid from said first chamber to the second chamber and prevents the flow of fluid from said second chamber to said first chamber. A slidable valve stem coupled to said check valve member and extending through the first chamber moves the check valve member from an open to closed position. Means coupled to said valve stem biases the slidable valve stem and check valve means toward the closed position. A recirculation valve means operatively coupled to said valve stem opens and closes said recirculation port, said recirculation valve means opening when said check valve means is closed and closing when said check valve means is open.

Abstract: The internal combustion piston engine for operation with gaseous or liquid fuels is equipped with a fuel metering system for compression of the fuel, which for each working cylinder (11, 11') has a piston compressor (20, 20') assigned to this on the cylinder head side with a compressor cylinder and a stepped piston (22, 22') axially movable inside this. The larger surface of the stepped piston (22, 22') is acted upon by the pressure of the combustion chamber of the assigned working cylinder (11, 11'), whilst the smaller surface of the stepped piston (22, 22') compresses the fuel when the pressure increases in the combustion chamber of the working cylinder. At least one overflow duct, which has an outlet into the combustion chamber lying in the slideway of the stepped piston and can be shut off or opened by a control edge of this piston, extends in each case between a compression chamber of the piston compressor (20, 20') and the combustion chamber of the assigned working cylinder. In each case two working cylinders (11, 11') with working pistons movable in opposition are assigned to one another and the stepped pistons of the piston compressors (20, 20') are positively coupled in opposition. …<IMAGE>…

Abstract: An axially magnetized linear force motor employs an exteriorly faced armature (4) having a first exterior face (14) and a second exterior face (16), wherein said first face (14) is acted upon by a first axial magnetic field established by a first annular, axially polarized, permanent magnet (22) and said second face (16) is acted upon by a second axial, magnetically opposing, magnetic field established by a second annular, axially polarized, permanent magnet (26). Actuation of a coil (32) affects the first and second fields oppositely causing an imbalance of net magnetic forces. The force imbalance causes the armature (4) to displace to a point where the net magnetic force equals a counter force established by a spring (10). Positionable ferromagnetic slugs (36, 37) alter the ratio of displacement of the armature (4) to the magnitude of a signal used to actuate the coil (32).
