Abstract:
In various embodiments of the present invention, tunable resistors (1102) are introduced at the interconnect layer of the integrated circuits (102) in order to provide a means for adjusting internal voltage and/or current levels within the integrated circuit to repair defective components or to configure the integrated circuit following manufacture. For example, when certain internal components, such as transistors, do not have specified electronics characteristics due to manufacturing defects, adjustment of the variable resistances of the tunable resistors (1102) included in the interconnect layer of integrated circuits according to embodiments of the present invention can be used to adjust internal voltage and/or levels in order to ameliorate the defective components. In other cases, the tunable resistors may be used as switches to configure integrated circuit components, including individual transistors and logic gates as well as larger, hierarchically structured functional modules and domains. In some cases, components and modules may be turned off, while, in other cases, components and modules may be turned on.

8146. Stewart, D., and Wishart, T. April 20. Switches.-Relates to electrically-actuated centrifugal machines of the self-balancing type. To facilitate the starting and stopping of the machine, the motor is controlled by a switch, Fig. 3, in which; upon turning the arm m in one direction, current is first directed through the armature c, one set of the coils h of the field magnets, resistances, and the other set of magnet coils, in series ; the resistances are gradually cut out ; then one set of the field-magnet coils is cut out ; next the two sets of magnets are placed in parallel for the steady running of the machine, and the resistance cut out. By moving the arm back beyond the central position, the current in the armature is reversed, which quickly brings the machine to rest.

19,362. Stewart, D. Oct. 30. Refining sugar.-An apparatus for separating liquids from solids may, according to the Provisional Specification, be used for the separation of sugar crystals from their syrups. The material to be treated is fed upon an endless band B, which consists of wire gauze attached to brackets C', Fig. 8, carrying chains C, and supporting, if necessary, a sheet of fabric which is held in place by clips C'. The faces C' of the clips are connected by flexible bent leather strips, so as to form edges which retain the material on the band. The band passes over vacuum boxes L' and under washing-pipes M and rakes M , and then over heating-boxes or coils P, which dry the solid matter to enable it to be removed by the scraper Q and brush R. The band is finally cleaned by washing-appliances U', and then dried. According to the Provisional Specification, strips of material, or " deckles," may be used instead of the retaining- edges of the band described above.

2510. Stewart, D. Feb. 8. Printing fabrics.-An apparatus for driving calico-printing, bleaching, washing, dyeing, finishing, and like machinery comprises a turbine A, having brackets B driven by means of three jets of water issuing from nozzles N. P, Q, respectively, carried by pipes R, S, T, which converge to a valve-box V. A valve V is mounted on a spindle W, and is actuated by means of a handle. The shaft D of the turbine carries a worm gearing with a wheel mounted on a shaft which transmits motion to the calico-printing or other machine through toothed gearing.
