Filed: 1984-04-20
Abstract: A composite structural element has a main steel beam having a web and at least two flanges extending therefrom, having oppositely directed outer faces, having outer edges generally defining a plane and defining with the web a recess open away from the web between the outer edges. A mass of concrete fills the recess substantially to the plane, the outer flange faces being exposed and substantially free of concrete. Another profiled steel beam is fixed to the web of the main beam and wholly imbedded in and covered by the concrete mass. Typically the main beam is an H- or I-beam and has two such channels provided with such other beams and filled with respective such masses. The other beams can be of T-section or each other beam can be an I- or H-beam. In addition it is possible to provide longitudinally extending steel reinforcing bars imbedded in the concrete mass. Steel fibers can also be imbedded as reinforcement in the concrete mass, and this mass can be at least partially of colloid concrete.

Patent EP-0173148-A3 (EP)
IPC: H03K17/60
Filed: 1985-08-09
Abstract: The present invention relates to a logic circuit which 
reduces occurrence of breakdown of a pull-down transistor 
(T₃) and a pull-up transistor (T₄; T₈) in the output stage when 
a high voltage is applied to the power supply line and 
ensures high voltage resistance. The logic circuit of the 
present invention controls the pull-up transistor (T₄; T₈) 
provided between a first power supply (V cc ) and an output 
terminal (OUT) for ON and OFF with a collector voltage of 
a phase splitter transistor (T₂) and controls the pull-down 
transistor (T₃) provided between the second power supply 
(GND) and the output terminal (OUT) with an emitter voltage. 
Breakdown of said pull-down and pull-up transistors (T₃; T₄; 
T₈) can be reduced and a high voltage resistance is ensured 
by providing a protection circuit (P) which discharges the 
base of pull-down transistor (T₃) and turns OFF said pull­
down transistor (T₃) by detecting a voltage difference be­
tween the first power supply (V cc ) and the second power 
supply (GND) when it exceeds the specified value.

Title: Organic nonlinear optical material
IPC: C07D319/18
Filed: 1987-05-20
Abstract: The present invention provides an organic nonlinear optical material comprising a benzylidene-aniline derivative having an electron-donating substituent introduced at the 4-position and an electron-accepting substituent introduced at the 4'-position, by following two contrivances: (l) selecting as the conjugated  pi electronic system a benzylidene-aniline derivative having a large molecular hyperpolarizability and yet a dipole moment as small as those of benzene derivatives, and (2) introducing a molecular alignment-regulating substituent. The centrosymmetry in the bulk state of the material, for example, in the crystal state, is destroyed and the molecular alignment is regulated to such a bulk structure in that the optical nonlinearity possessed by the molecule is effectively utilized. The material shows even a large optical nonlinearity never attained by the conventional techniques. The intermolecular cohesive force due to the  pi electron interaction between the molecules in the present invention is larger than that between benzene derivatives. Consequently, the material has, comparatively, a high melting point, a low subliming property, and a low water-absorbing property. In conclusion, a practically invaluable nonlinear optical material having a high durability in the bulk state and an excellent resistance to laser damage can be provided.

IPC: H01L29/06
Filed: 1987-10-30
Abstract: A PN junction having an enhanced breakdown voltage 
is made by forming a silicon dioxide or other 
insulating layer (56) over the PN junction of the 
diode. The silicon dioxide layer is then implanted 
with ions. Depending on the species implanted into the 
silicon dioxide layer, the silicon dioxide layer 
becomes resistive. The metallization (58,60) 
contacting the anode of the diode and the cathode of 
the diode also contacts the doped silicon dioxide 
layer. Electrical fields caused by current flowing 
through the doped silicon dioxide layer (56) alter the 
radius of curvature of the depletion region between the 
anode and cathode, thereby enhancing the diode 
breakdown voltage.

zone is 75 to 105° and the angel (β) between the sorting zone and the 
centre-line (8) of the shaft of the rotor (2) is 75 to 105°, and that 
the defibrating zone and the sorting zone are located in the same pulp 
space (5).

Patent EP-0300663-A3 (EP)
IPC: G01S7/491
Filed: 1988-07-12
Abstract: There is disclosed an optical ranging system adapted for use with 
widely varying return signal levels. Automatic signal level control is achieved in 
two parts, a passive optical part and an active electronic AGC part. The optical 
part is based on the coaxial arrangement of transmitting and receiving elements in 
which the shielded transmitting element is mounted in front of the receiving 
element, which includes a Fresnel lens which comprises a plastic casting. The 
electronic AGC portion of the system includes means for providing a voltage 
drive (with low internal impedance) for the final AGC transistor when it would 
tend to be slow, so little phase shift in the control results from changes in the 
signal levels. Thereby, the determination of distance (the ranging) by phase shift 
measurement is kept reliable as signal level changes. This optical ranging system 
is especially adapted for mounting on autonomously guided vehicles (robot carts), 
which are important for material handling and inventory control in manufacturing 
system in factory environments.
