Abstract: In order to reduce the thermal stress on surface-mounted (SMD) components (6 - 8), such as miniature resistors, capacitors and integrated circuits, during soldering of their edge-side metallic solder terminal elements (6a - 8a) to printed-circuit board metal terminal surfaces (4a) on the component side (2) of a printed-circuit board (1), at least one solder hole (15) is arranged underneath each solder terminal element. Before flow or wave soldering from the solder side (3) of the printed-circuit board (1), the components (6 - 8) are fixed in their desired position by means of spots of adhesive (13). The soldering process is particularly suitable for the mixed furnishing of the printed-circuit board (1) with wired and wireless components, it also being possible to arrange less temperature- sensitive, surface-mounted components in the conventional manner on the solder side (3) of the printed-circuit board (1). <IMAGE>

Abstract: A crossbar converter to format 32 bit raster formatted I/O data into 5 X 4 patch formatted eight bit pixel data enables a 160 bit wide pixel data bus to be used so as to attain a high bandwidth for I/0 devices. By using the wide pixel data bus and patch format for I/O, the facilities of the an screen memory and an arbitrary shape clipper can be made available to process a real time video window on a high resolution, bit mapped display monitor. The crossbar converter can be used to convert the parallel input of standard I/0 devices into patch format, (five by four by eight, for example). The thus converted I/O data may be used by an off screen memory and an arbitrary shape clipper at high transfer rates.

Abstract: A memory element of the present invention is split to minimize the magnitude of electrical current flowing therethrough as the split memory element is being heated to its transitional temperature, thereby permitting the cross-sectional area of the lead wires used to conduct an electric current to the memory element to be minimized. The split memory element includes a tip member and first and second strip members aligned in side-by-side relation. Each of the tip member, first strip member, and second strip member are made of a shape-memory alloy and have a characteristic internal structure. Each strip member includes a shape-memory portion coupled to the tip member, a lead-attachment portion, and partition means for interconnecting the shape-memory and lead-attachment portions. Each partition means has an internal structure which is dissimilar to the characteristic internal structure of the tip member and the first and second strip members so that certain ions originating in the electrically conductive wire lead coupled to the lead-attachment portions are substantially isolated or otherwise contained in the lead-attachment portions to prevent contamination of the shape-memory portions.

Abstract: Method and device in a machine for the manufacture of paper or board for heating the outer face (10′) of such a cylinder or roll (10) as is in direct contact with the web (W) to be pressed against said roll face. The cylinder or roll face (10′) is heated from outside inductively by using a magnetic field, by means of which a heating effect based on eddy currents is produced in the outer layer (3) of the roll. As the cylinder or roll face (10′), a relatively thin outer layer (3) of an electrically conductive ceramic material is used, in which the resistive heating effect is concentrated. The depth of penetration of the heating effect in the radial direction of the roll to be heated is restricted to a sufficiently low depth by means of the choice of the thickness of the ceramic outer layer (3) and/or of the electric frequency (f) of the induction heating. Besides on the basis of its electric properties, the ceramic material of the outer layer (3) is chosen so that the cylinder or roll face (10′) is given the necessary properties of strength, also in view of the thermal shock of the heating effect.

Abstract: A packet network routing method and system based on geographic coordinate identifiers is described. Each node in a network is uniquely identified by absolute geographical coordinates or by a code indicating absolute location in an external coordinate-based reference system (node coordinates), and such absolute geographical coordinates or the equivalent are employed as part of a packet identifier for each packet generated for use in making routing decisions. The node coordinates of a local node and its neighboring nodes and the packet coordinates are used by means at each node through which a packet is routed for determining a desired forwarding route of a data packet. The routing may be prioritized according to preselected criteria, preferably achieving maximum forward progress using the least amount of power. The packet routing protocol according to the invention requires no routing directory or table to perform data routing.
