Patent EP-0029502-A1 (EP)
Inventor: LEE ROBERT POON-LUN
IPC: H04L12/56
Filed: 1980-10-15
Abstract: A communication system for data packets comprises a multiplicity of nodal units inter-connected in an inverted tree hierarchy by a network of duplex data channels. Each unit (1, 20 or 22) comprises an up-port (33') connected to another unit at a higher level or, in the case of the root nodal unit, via a loop line (3) back on itself. Each unit further comprises a plurality of down-ports connected to other nodal units (e.g. node 5) at lower levels or to terminal transceiver devices (e.g. port 40). The system operated for transmission up the hierarchy on a demand assignment basis whereby the demand detect logic (63, 65 or 67) which is first to detect incoming data, produces the first request signal RQ. This first request signal causes its own access control unit (57, 59 or 61) to provide a gating signal to its associated gate (51, 53 or 55) and an inhibit signal to the other access control unit. Data is broadcast downwardly, data arriving from a higher level is routed to all the next lower level nodes (2, 3 and 4).

Abstract: Semiconductor crystals for use, for example, in the manufacture of integrated circuits are required to be inspected for crystal lattice perfection before any subsequent circuit processing. This can be done by X-ray diffraction in which the crystal (1) is curved so that a divergent beam irradiates all points of the crystal surface at the same angle and simultaneously. The difficulty is however, in holding the crystal (1) in the appropriately curved form while at the same time not obstructing the passage of X-rays from the front or back of the crystal and so enable topographs to be obtained by both reflection and transmission. According to the invention, in such a system the crystal (1) is attached to a flat, X-ray transparent plate (6) by pneumatic X-ray transparent means, and the plate (6) is deformed to the required curvature, carrying the crystal (1) with it.

Abstract: A flow line 14 has weight elements 42 connected thereto for making the combination negatively buoyant. At rates of speed above a threshold level, the weight means creates an upward lifting force as the flow line is towed through a body of water 6. The flow line also has depressor elements 44 connected thereto to apply a downward force to the flow line to offset the lifting force created by the weight elements. The depressor elements are located adjacent the weight elements to prevent an oscillating or "snaking" motion from being imparted to the flow line as it is towed through the body of water above the threshold level.
