Abstract:
The present invention relates to a stepwise adjustable attenuator especially for use in volume control of audio-signals in amplifier systems and generally for attenuation of electrical signals in other appliances. The new solution provided according to the present invention consists of the electric resistors being surface-mounted devices (SMD resistors) which are mounted quite close to the wafer terminals. Hereby the series-inductance, the stray capacitance, the distortion, the length of the signal-path and the interference of electric fields from noise sources are decreased and as a result of this the attenuator's bandwidth for the electrical signal frequencies is increased and the compact design is advantageous in new designs as well as for upgrading existing appliances.

Abstract:
The invention relates to an electrical resistor (1) comprising an electrically conductive stack (10), which comprises a plurality of metal first layers (12) and second layers (14). The stack 10 allows to produce a highly anisotropic resistor (1), in which the resistance in the direction perpendicular to the layers (12, 14) is much higher than in the plane of the layers (12, 14). The anisotropy allows the current flowing through the stack (10) to be made homogenous, i.e. to be distributed over the entire stack surface, even if the current is input into the stack (10) in an inhomogenous manner.

An electronic device (100), e.g . a trimmable resistor, includes a plurality of fused resistors having progressively larger resistance values. Optionally the resistance values form an exponential progression. Each fused resistor includes one or more doped resistive regions (410) formed in a semiconductor substrate, the doped resistive regions optionally being thermistors.

First (125) and second (130) interconnection buses are located over the substrate, with the first interconnection bus connected to a second terminal of each of the fused resistors, and the second interconnection bus connected to a second terminal of each of the fusible links.

Abstract:
Sistema de control remoto de la posición eléctrica de un potenciómetro que, insertado en las conexiones de sus extremos al sistema de control original, ofrece entradas de control que permiten que un sistema de control secundario o remoto modifique eventualmente el balance de resistencias a ambos lados del cursor del potenciómetro, y con ello su posición eléctrica, manteniendo invariable la resistencia vista por el sistema de control original cuando se activan sus entradas de control, gracias a un circuito base que realiza la inserción de una resistencia en serie con uno de los extremos del potenciómetro, y conecta una resistencia en paralelo que permite compensar la variación de resistencia equivalente, y con unos algoritmos de cálculo que permiten obtener y ajustar con facilidad los valores adecuados de los componentes para una amplia gama de aplicaciones, valores de potenciómetros y márgenes de control.
Abstract:
An arrangement of a heating element into divided zones of intermingled groups is provided. The heating element arranged circumferentially about an exterior of a heating zone of a furnace, in combination with a fault tolerant circuit that provides for the same power characteristics to an assembly of electrical resistive elements wired in parallel as to the assembly as wired in series is also provided. Redundancy and fault tolerance is provided to a heating process using the combination because the circuitry permits remaining load elements to continue to operate should one or more load elements fail and the intermingled arrangement maintains a balanced application of heat.

A multi-directional input device, wherein, when an elastic driving body (13) is tilted, an elastic pressing part (13B) presses the upper surface of a flexible insulation substrate (15) to bring a circular ring-shaped upper resistance layer (16) on the lower surface of the flexible insulation substrate (15) into contact with a lower conductive layer (17) opposed to the upper resistance layer and, in this state, a calculation device (not shown) recognizes the tilted direction and tilted angle of the elastic driving body (13) based on the information from the lead-through parts of the upper resistance layer (16) and the lower conductive layer (17).
