Patent EP-0389721-A3 (EP)
Title: Flash eprom cell and method of making such cell
IPC: H01L29/792
Filed: 1989-12-22
Abstract: A flash EPROM cell is fabricated using a two 
polysilicon enhancement mode n-channel transistor process. 
An active transistor region is formed in a silicon substrate 
(14) by growing a field oxide (16) around the region. A 
first polysilicon layer is deposited, etched, and oxidised 
to form an insulated control gate electrode (18). A second 
polysilicon layer is deposited over the active transistor 
region and the control gate electrode (18) and then 
anisotropically etched to remove all of the second 
polysilicon material except for a filament (20) adjacent to 
the control gate electrode (18), which forms a floating gate 
electrode (20). Source and drain regions (10, 12) are 
formed in the active transistor region with the control gate 
electrode (18) and the floating gate electrode (20) 
positioned over the channel region interconnecting the 
source and drain regions. The cell is programmed by hot 
electron channel current injection by proper voltage biasing 
of the control gate electrode (18) and drain (12). The cell 
can be either symmetrical or asymmetrical depending on the 
configuration of the floating gate filament electrode (20).

Title: Device for bringing together a plurality of infusions and/or injections
IPC: A61M39/00
Filed: 1990-12-22
Abstract: The invention relates to a device for bringing together a plurality of infusions and/or injections, with a housing (1) through which the infusion/injection fluid flows, and with a plurality of accesses (2) which are arranged in a radiating pattern and can be closed off separately in each case, and with an outlet (3) for the liquid brought together. 
<??>In order to ensure a reliable activation-free sealing of the individual accesses by simple constructional means, while maintaining a simple production of the device, the invention proposes that the housing consist of a first housing part (1a), which has the accesses, and a second housing part (1b), between which parts an elastic sealing element (11), which extends at least over the radiating angle of the accesses, is held in the outer area of the circumference. Each access opens into a sealing element opening space (18) connected to the outlet, and the sealing element section (11a) allocated to the respective opening space is pre-tensioned towards the access.

Title: High speed numerical processor
IPC: G06F7/535
Filed: 1990-04-05
Abstract: Division and square root calculations are 
performed using an operand routing circuit (16) for 
receiving an operand N, and operand D and a seed value S 
and directing the operands and seed value to a multiplier 
(38). Single multiplier (38) is configured into two 
arrays for calculating partial products of N and S and D 
and S. The results of multiplier (38) are transmitted 
through switching circuitry (20) or registers (48)(50)

depending on a convergence algorithm. The final result is 
rounded.

Title: Method and apparatus for surface marking
IPC: B24B19/02
Filed: 1990-05-17
Abstract: The invention provides for the marking of 
surfaces, for example, those of glass laboratory vials, 
which are marked by removing surface material 
therefrom. The vial (24) is moved relative to material 
removal means, for example a grinding wheel (10), under 
the control of a computer (50) so as to grind a desired 
bar code or alphanumeric symbols into the vial surface 
24B. The ground portion of the vial surface 24B 
scatters light while the unground portion of the 
surface transmits light, the ground pattern can thus be 
read by optical reading means, for example bar code 
reading means. The process may be automated and 
performed by a robot as part of an analyzing or 
processing system.

Title: Piston zeroing device for flowable material dispenser
IPC: G01F11/04
Filed: 1990-08-29
Abstract: An adjustable dose dispenser having a measuring chamber of constant cross-section defined in a housing wherein an end of the chamber is selectively placed in communication with a reservoir containing flowable material to fill the chamber and with a passage to discharge material from the dispenser, and including a piston movably mounted in the housing and having an end face located in the measuring chamber so as to define the measuring volume between the piston end face and the end of the chamber. A manually operable drive mechanism is movably carried by the housing and has formations thereon operatively engaging formations on the piston so that upon movement of the drive mechanism the piston end face is moved along the measuring chamber to vary the volume thereof and so that dimensional control of the volume of the measuring chamber is determined by tolerance associated with misalignment of the formations on the piston and drive mechanism. The formations preferably are fine pitch gear teeth, and the piston and drive mechanism are installed in the dispenser in a manner such that the total tolerance associated with the volume of the measuring chamber is defined as the circular pitch of the gear tooth, i.e., the maximum misalignment between the gear teeth on the piston and on the drive mechanism.

Patent EP-0563765-A3 (EP)
Title: Circuit for producing an electrical voltage reference value depending on an electrical control voltage
IPC: G05F1/46
Filed: 1993-03-24
Abstract: An RC section (12, 13) connected between feed lines (+, 0) is connected to the first input of a comparator (9). The second input of the comparator (9) is connected to a fixed voltage divider (10, 11). The output of the comparator (9) is connected to the first input via another resistor (16). The capacitor (13) of the RC section is charged up via the resistor (12) of the RC section until the voltage at the first input reaches the fixed voltage at the second input. The output of the comparator (9) then discharges the capacitor (13) via the further resistor (16) whereupon the capacitor (13) is charged up again. The periodic exponential capacitor voltage is supplied to the first input of a further comparator (7), at the second input of which the adjustable control voltage is present. When the voltages are equal, a voltage change occurs at the output of the comparator (7) which is transferred to a switching transistor (23) via an optocoupler (19). The signal present at its output and smoothed forms a voltage reference value which quasi-logarithmically depends on the settings of the control voltage and can be used, for example, for controlling the brightness of low-voltage gas discharge lamps. <IMAGE>

Inventor: KOIVUKUNNAS PEKKA
IPC: D21G1/00
Filed: 1995-10-06
Abstract: In a method and apparatus for calendering a surface of a moist paper or
board web (W), a temperature difference is created between the web surfaces so that the surface to
be calendered is cooler than the opposite surface. In addition, moisture within the web is
transferred using the so-called heat pipe effect toward the cooler surface while substantially
preventing evaporation of moisture from the web so as to create a predetermined moisture
profile transversely through the web and decrease the glass transition temperature of the web at
the relatively cooler surface to be calendered. Finally, the web having the predetermined
moisture profile is advanced into the calendering nip (N1) so that the relatively cooler and moister
surface of the web is pressed against the heated roll (4 1 ) of the nip (N1) to
thereby calender that web surface.
