Abstract: A resistance substrate contains a substrate and a resistance part that is formed on an upper surface of the substrate by printing. The resistance part is formed into an arc shape (a C shape) so that a width of the resistance part continually changes. The resistance part is formed so that a part having a narrow width becomes thick and a part having a narrow width becomes thin.

Abstract: A strip conductor comprises a first layer with at least one curved section. At least one region of the curved section provided with an additional layer having a smaller resistivity than the first layer. The at least one region is constructed such that resistance on tracks of different radii of curvature is approximately equalized.

Abstract: A chip-type variable resistor is provided which includes an insulating substrate formed with a resistor strip which is arcuate at least partially and has both ends electrically connected to respective extremity electrode terminals, an intermediate terminal member mounted to the substrate, and a contact member electrically connected to the intermediate terminal member and rotatably mounted to the substrate in slidable contact with the resistor strip. The resistor strip includes at least one portion having a lower area resistivity (defined as a resistance per unit surface area) and at least another portion having a higher area resistivity.

Abstract: An electric potentiometer including a wiper lever having brush wipers, which upon a rotational movement about a pivot shaft sweep over electrically conductive layers applied to a carrier plate. A resistor layer is joined at one end to a connection layer and at the other to a grounded connection layer. The layer is joined at one end to a pickup connection layer and at the other, via a supplementary layer resistor, to the connection layer. A sliding layer of electrically non-conductive paste material is disposed between the carrier plate and the resistor layer, the latter of which is formed from a paste material provided with carbon particles. The sliding layer is wider than the width of the wiper and the resistor layer.

Abstract: An electric potentiometer is proposed which serves to convert a mechanical movement into an electrical value. The potentiometer includes a pickup embodied as a wiper and a resistor pad which has a plurality of connections for parallel resistors distributed over the displacement range of the pickup and serving as support points. With these parallel resistors, the partial resistance established by the pickup can be varied to a predetermined course. The support points extend crosswise to the contact track of the pickup on the resistor pad and are embodied as only so long that they terminate before reaching the contact track.

Abstract: An electrically heated window is disclosed which achieves a more uniform current density at the interface between the resistive heating layer and the current-bearing electrodes to which it is connected. In one embodiment this may be achieved by forming the edge of the electrode in an undulating shape. It may also be done by increasing the surface resistance of the electrode near its edge by, for example, forming the edge so that it is wedge-shaped in cross-section. More uniform current density may also be achieved by using an electrode which has a resistivity that is greater than that of the resistive heating layer. It may also be achieved by use of a high resistivity layer located between the electrode and the resistive heating layer.

Abstract: In a variable resistor of the type wherein there is formed on an insulating substrate a resistive member having wide portions and narrow portions in the sliding direction of a slide member and ends thereof wired respectively to a ground terminal and an input terminal. A plurality of contact elements formed on said slide member are brought into sliding contact with said resistive member and a high resistance film allowing the passage of electrostatic charges therethrough is formed at portions of said insulating substrate lying within the sliding passage of said contact elements so that a part of said contact elements comes into contact therewith when it comes off from said resistive member.

Abstract: A resistance disk that is so constructed that as the disk is rotated between a pair of fixed contact members, there is produced between the contacts a varying and random like resistance pattern of a character unobtainable with any other form of resistance apparatus and further including the feature whereby the varying resistance pattern may be selectively altered by radial movement of one of the contact members across the face of the disk.

Abstract: An electrical resistance element for use in variable resistance devices such as trimmers and potentiometers, having two or more resistance materials on a non-conducting base. The resistance materials are aligned along a path of travel of a movable wiper or contact to provide a series of variable linear resistances or a non-linear resistance. The interface between the resistance materials is arranged so that individual contact elements of the wiper traverse the interface at different times.

Abstract: This invention relates generally to electrical resistors and particularly to a resistor disk and contact assembly wherein by reason of the structure of the disk, the radial resistance of the disk is randomly varied to produce a random-like resistance pattern of a predetermined configuration as the disk is rotated between fixed engaging contacts.

Abstract: A variable-resistance attenuator having first and second resistive layers deposited upon an insulating substrate. Input and output terminals are electrically connected at spaced intervals to one of the resistive layers and a common terminal is electrically connected to the remaining one of the resistive layers. A pair of contacts are adapted to make slidable electrical engagement, each with an associated one of the resistive layers. Conductive bridging means mechanically and electrically connect the sliding contacts. Mechanical means are provided for simultaneous movement of the sliding contacts to change the resistance in a smooth and continuous fashion.
