Patent CA-2016190-A1 (CA)
Title: Current-based computer logic architecture
Inventor: POPPELBAUM WOLFGANG J
IPC: H03K17/76
Filed: 1990-05-07
Abstract: ABSTRACT          Disclosed are basic forms of logic cells which can be readily provided and interconnected to perform many types of functions as desired.  In accordance with the invention, a current-based logic cell includes one or more sections each of which may be a quite simple circuit and which in one embodiment may consist essentially of two diodes, a current source and connecting wires.          In other embodiments a transistor and other components may be added.  In each embodiment, a circuit is provided which includes an input wire to which a plurality of input signals may be applied, each input signal being in the form of a current, and processing circuitry which responds to the net current flow in the input wire to control development of an output signal.  High switching speeds are achieved by using very small voltage swings, avoiding satura-tion and minimizing the effects of capacitances.  Preferably, the circuit includes an output wire in which a current is developed which corresponds to the net current flow in the input wire of the section and which forms the output signal of the section.  As a result, the input wire of a section may be directly connected to output wires of two or more other sections of the same or similar form, simplifying the interconnection of cells and reducing the length and shunt capacitances of connections between cells, to minimize propagation delays.

Title: Method of manufacturing semiconductor devices
Inventor: BULAT EMEL S
IPC: H01L21/335
Filed: 1990-08-14
Abstract: METHOD OF MANUFACTURING SEMICONDUCTOR DEVICES            ABSTRACT    In fabricating a junction field effect transistor, specifically a static induction transistor, an epitaxial layer of high resistivity N-type silicon is grown on a substrate of low resistivity silicon.  The surface of the epitaxial layer is marked in a pattern to expose a plurality of elongated surface areas.  The wafer is subjected to reactive ion etchings in SiCl4 and Cl2 and subsequently in Cl2 to form parallel grooves with rounded intersection between the side walls and bottoms of the grooves.  Ridges of silicon are interposed between grooves.  A layer of silicon oxide is grown on all the silicon surfaces.  The grooves are filled with deposited silicon oxide and silicon oxide is removed to form a planar surface with the upper surfaces of the ridges. P-type conductivity imparting material is ion implanted into alternate ridges and diffused to form gate regions which extend laterally beneath the silicon dioxide in the adjacent grooves, N-type conductivity imparting material is ion implanted in the top of the intervening (source) ridges.  Metal contacts are applied to the gate ridges, source ridges, and the bottom of the substrate.

Abstract: A  service  network  has  several  computer  systems connected together.   A computer  system  can  either be  a "Service Requestor"  (SR),  a "Service Provider"  (SP), or a hybrid of the two,  a "Service Provider/Requestor"  (SP/R). The  computer  systems  in  the  service  network  have  the capability to perform or request problem prevention.  A SP (or SP/R acting as a SP) can check to see if it has any solutions to problems that one or more of the SRs (or SP/R acting as an SR) it supports has but has not discovered or reported  yet.    If   so,   it   can  distribute   solution information, accompanied by one or more software components, microcode components, hardware parts order,  and/or textual instructions, to the SRs.  In addition, a SR (or SP/R acting as an SR) can request any known fixes to problems for a list of supported components from an SP (or SP/R acting as an SP). The SP sends any fixes to problems associated with the list of supported components to the requesting SR.

Abstract: ABSTRACT       A machine for production of finished lath packs for venetian blinds, which have holes at the ends for draw cords and ladders (3)  consisting of bands or strings, every cross band of which carries a lath, and where two neighbouring cross bands of a ladder are placed on each side of the draw cord passed through the holes (8), which machine has a mechanism which inserts laths (2) one by one over a cross hand in the suspended ladders (3) and at each ladder a mechanism (1) which lifts the inserted lath and the ladders (3) as well as devices to retain the raised lath.   Each lifting mechanism has a carrier (1) with a slit through which the ladder (3) stretches and, on both sides of the slit, carrier faces (5) sloping away from each other for an inserted lath (2).  The carrier can tilt in such a way that the carrier faces support the laths alternately.  The carriers are tilted synchronously with the movement of the feed mechanism.  The carrier (1) is thus  used  also  for  positioning  the  ladder  with  the consecutive cross bands placed on one and the other side alternately of the draw cord.

Abstract: ABSTRACT A shaping-material or filler for textiles such as bedspreads, garments or the like is disclosed consisting of a large number of fiber aggregates of a maximum length of 50 mm each. The fiber aggregates are smaller and softer than down in nature and essentially all the fibers are crimped with the fibers of the individual fiber aggregates being arranged randomly inside each aggregate. A filler is created thereby which is especially suitable for textiles such as bedspreads, or garments such as jackets, coats or the like, the filler being enclosed in an envelope. This filler can be made to vary in thickness with surface distribution, in the manner known for fiber balls and down. However, the filler has little shift, even if the textile is vigorously shaken, and nevertheless, is very soft.            A method for manufacturing the textile is also described.
