Patent EP-0312016-A3 (EP)
Title: Linear differential amplifier
IPC: H03F3/45
Filed: 1988-10-12
Abstract: A differential amplifier with improved linearity is 
disclosed. The amplifier includes a circuit comprised 
of two emitter-coupled pairs (10,20), each pair (10,20) 
being formed by two transistors (Q₁,Q₂;Q₃ Q₄), 
with connections between corresponding collectors 
(11,13;12,14), and constant voltage sources (E₁,E₂) 
for producing offsets between corresponding bases 
(1,3;2,4) of the emitter-coupled pairs (10,20). The 
improved linearity is achieved by obtaining outputs as 
sums of collector currents with offsets. The emitter 
areas of the transistors can be of the minimum size 
available. This feature, when combined with the use of 
emitter-followers as the constant voltage sources 
(E₁,E₂), enable the differential amplifier to 
achieve a high S/N ratio, a good high-frequency 
characteristic, a high direct current gain, and a 
high-speed operation capability along with the improved 
linearity.

Abstract: There is provided a functional ZnSe:H deposited film 
composed of zinc atoms, selenium atoms, and at least 
hydrogen atoms, with the content of hydrogen atoms being 1 
to 4 atomic% and the ratio of crystal grains per unit 
volume being 65 to 85 vol%. It is capable of efficient 
doping and is stable to irradiation. It can be made into 
a high conductivity p-type of n-type ZnSe:H:M film by 
doping. It can be efficiently deposited on a non-single 
crystal substrate such as metal, glass, and synthetic 
resin which was incapable of efficient depositing. Thus 
the invention makes it possible to form a high-functional 
device such as a photovoltaic element of ZnSe film on a 
non-single crystal substrate.

Title: Tamperproof snap-on closure
IPC: B65D41/48
Filed: 1988-12-20
Abstract: The tamper-proof snap-on closure (1) is particularly suitable for bottles with beaded edges on the bottle neck. The tamper-proof safeguard is effected by a shear-off element (4) which consists of a push piece (9) and is bounded on both sides by weak points (5, 6). The shear-off element (4) forms part of the shell. In order that the shear-off element (4) does not tear further than is desired, the weak points (5, 6), running in the axial direction of the closure, extend only into the region of an annular bead (2) arranged on the inside surface of the shell. The shear-off element (4) itself, which has at least one rib (11), is connected to the shell via a film hinge and can be swivelled through 90 DEG , thus destroying the weak points.

Title: Apparatus for preventing undesired fluid flow past a flow control location
IPC: B41F33/00
Filed: 1989-11-17
Abstract: An apparatus is disclosed for controlling fluid flow at 
a flow control location between first and second rollers (12, 16). 
Each roller is rotatable about its longitudinal central 
axis. The two rollers (12, 16) are disposed adjacent to each other 
so as to form a flow control location or nip (18) between the 
rollers. The nip (18) has an entrance side (11) and an exit side (13). 
As the rollers (12, 16) rotate, fluid from a fluid pan (14) is carried on 
the outer surface of the first roller (12) to the entrance side (11) 
of the nip (18). Some of the fluid at the nip (18) is transferred 
onto the outer surface of the second roller (16). As the 
rollers (12, 16) continue to rotate, the fluid flows out of the nip 
at the exit side (13) of the nip (18). An excess fluid condition 
occurs at the nip (18) when the amount of fluid flow to the 
entrance side (11) of the nip (18) exceeds the amount of fluid flow 
from the exit side (17) of the nip (18). A brass collar (30) is connected 
at one end of the first roller (12). Another brass collar (35) is 
connected at the other end of the first roller (12). The two 
brass collars (30, 35) rotate with the first roller (12) and cooperate to 
prevent excess fluid at the entrance side (11) of the nip (18) from 
flowing around the opposite axial ends of the nip (18) onto the 
second roller (16). This is accomplished by the two brass 
collars (30, 35) picking up excess fluid at the entrance side (11) of the 
nip (18) and subsequently transferring the excess fluid back to 
the fluid pan (14).

prevent buildup of potential differences between the circuits. In 
one embodiment, the capacitive elements are reference cells 
consisting of liquid crystal display cells formed by two mutually 
opposed electrodes between which is sealed a liquid crystal 
material.
