Patent EP-0325186-A3 (EP)
IPC: A61M39/28
Filed: 1989-01-16
Abstract: The invention relates to an air trap for closing synthetic tubes, especially infusion tubes, which air trap, for example in blood transfusion, reliably provides for an automatic closing-off of the blood supply if air bubbles appear in the infusion tube. For this purpose, the air trap for closing synthetic tubes, especially infusion tubes, has a flat head which, under the action of a spring, on the one hand bears against the membrane (Teflon membrane) of a pressure chamber while, on the other hand, it engages with its guide rod around a tube passage in such a way that, when there is a gas pressure in the chamber, the tube passage is cleared and, when the chamber is free of pressure, the tube passage is closed off with engagement by the guide rod under the action of a spring.

Filed: 1990-02-09
Abstract: To connect the individual bars (2) and supports (3), if any are present, of a framework structure, connectors having in a customary manner connector openings (4) and connector projections (5) are provided. In order that the connection process and also the detachment of the connection can be carried out as simply and quickly as possible and nevertheless a secure and firm connection can be obtained, retaining pins (6) which can be laterally deflected counter to a restoring force are provided inside the particular connector opening (4), within the clear cross-section thereof. The connector projection (5) which fits into the connector opening (4) has a sloping face (7) or tip which, on insertion, impinges on and moves apart these retaining pins (6) and, adjoining said oblique face or tip, an aperture (8) which recedes radially with respect to the largest cross-section of the connector projection (5) and into which the retaining pins (6) can thus spring back again, with the result that the first loose connection is already made. Adjacent to this aperture (8) in the circumferential direction there are provided regions (9) which, on relative rotation of the connector projection (5), deflect the retaining pins (6) in turn radially as far as the outer dimension of the connector projection (5), so that the connector projection (5) can be very easily drawn out of the opening (4) again or, conversely, the opening (4) can be very easily withdrawn from the projection (5). To secure the play-endowed connection, there is furthermore provided in the region of the connector projection (5) a sliding or screw sleeve (11) which, in the connected position, can be adjusted and locked relative to the surface region adjacent to the connector joint, with the result that the connector projection (5) and especially the radial boundary (8a) of its aperture (8) is clamped against the retaining pin (6) counter to the insertion direction.

IPC: H01L27/108
Filed: 1990-05-10
Abstract: The described embodiments of the present invention provide a 
memory cell and method for fabricating that memory cell and 
memory array including the cell. The memory cell is a trench 
capacitor type having a transistor (1-1-2) formed on the surface 
of a major face of a substrate (16) and having a capacitor 
(2-1-2) formed in the substrate around the periphery of a trench. 
The capacitor and transistor are connected by a buried, heavily 
doped region (26) having the opposite conductivity type from the 
substrate. A doped storage area (24) having the same doping type 
as the buried doped region surrounds the trench. A field plate 
(30) is formed in the trench separated from the storage region by 
a dielectric layer (32). The field plate extends onto the 
isolation areas between memory cells thus providing isolation 
between cells using a minimum of surface area. A self-aligned 
process is used to form the source (14) and drain (12) for the 
pass gate transistor and automatic connection between the source 
of the transistor and the buried doping layer is made by the 
buried N+ layer. A sidewall silicon nitride passivation filament 
(38) is formed to protect the sidewalls of the interlevel 
insulator region between the first (30) and second (3-3, 3-4) 
polycrystalline silicon layers.

Title: A neutron source monitor for an accelerator neutron source
IPC: G01T1/16
Filed: 1986-06-05
Abstract: In the illustrative embodiments of the invention disclosed, a neutron porosity well logging tool includes a D-T neutron accelerator and a fast-neutron monitor for monitoring accelerator output. The monitor comprises an organic scintillator having a characteristic dimension that is small relative to the average range of gamma ray-induced electrons that would produce high pulses of magnitudes comparable to those resulting from recoil protons produced by source neutrons, while it is large relative to the average range of such recoil protons. The scintillator is coupled via a photomultiplier to a pulse height discriminator circuit that passes pulses in the higher-energy flat portion of the spectrum. Consequently, the neutron source monitor produces a signal that is proportional to the intensity of the neutron source. <IMAGE>
