Abstract: A method for efficiently manufacturing chip resistors is provided. A method for efficiently manufacturing chip resistors includes the steps of preparing at least three conductive elongated boards made of an electrically conductive material and a resistive member made of a resistive material, arranging the at least three conductive elongated boards apart from each other along a width direction crossing a longitudinal direction in which one of the at least three conductive elongated boards is elongated, forming a resistor aggregate by bonding the resistive member to the at least three conductive elongated boards, and collectively dividing the resistor aggregate into a plurality of chip resistors by punching so that each of the chip resistors includes two electrodes and a resistor portion bonded to the two electrodes.

Abstract: A shunt strip that includes a plurality of shunts arranged in a grid with each of the shunts spaced from an adjacent shunt by a shunt-gap. A plurality of tabs connect the plurality of shunts and at least one tab is positioned within each shunt-gap. Also, a shunt with a generally parallelepiped shaped body has severed tab portions extending outwardly and downwardly from the body.

Abstract: A zipper system includes a zipper mechanism having interlocking teeth, the teeth, when interlocked, closing a signal circuit to an audio playback circuit, the audio playback circuit. The audio playback circuit includes a microprocessor. The microprocessor includes an audio track storage and control instructions that, when executed by the microprocessor, cause playback of an audio track from the audio track storage. The audio playback circuit further includes a speaker device coupled to the microprocessor that broadcasts the audio track.

Abstract: A shunt resistor includes a resistive body and a pair of electrodes each bonded to the resistive body. The resistive body has an obverse surface and a reverse surface that face in mutually opposite directions. The two electrodes are separate from each other in a first direction perpendicular to the thickness direction of the resistive body. The resistive body has two ends separate from each other in the first direction. The obverse surface of the resistive body includes a pair of intentionally curved portions that are located at the two ends of the resistive body.

Abstract: A current shunt for converting a current to a voltage. The current shunt of the invention is made from a conductive material such as a high performance resistance alloy in sheet form which is sheared, punched, and bent to produce a highly stable current shunt with respect to time and temperature. Contact pins of current and potential connections are welded to the material using a fusion welding process, and techniques are also provided for isolating the potential contacts from the current contacts so as to improve stability. Trimming slits of the type used for thin film or foil resistors are also extended to bulk materials in accordance with the invention such that highly accurate resistances may be obtained. An integral heat sink and strain relief mechanism is also provided so as to minimize the adverse effects of temperature on the resistance of the material. The resulting current shunt has an extremely stable resistance value with respect to time and temperature at a minimal cost.

Abstract: A current shunt device has main and auxiliary windings which are located in substantially the same position and are connected in series.

Abstract: A sensor is disclosed for detecting the position of a movable part in a motor vehicle with a common drive for several position pickups and several paths. The individual paths are traversed at least partly consecutively over the total range so that a position signal with different resolution depending on the path can be made available. This is accomplished by means of individual paths corresponding to different places in the total range. The paths are in the form of resistance paths. The signals picked up can then be associated with electrically different paths for further processing. Paths having the same resolution are also possible.

Abstract: A variable attenuator comprises a generally horseshoe-shaped main resistance element, a sliding member movable thereover, and a bypass provided around that portion of the main resistance element adjacent the end portion of the path of said sliding member. The bypass is made of a conductive element or conductive element and a resistance element, the amount of current flowing through said bypass being thereby increased to enable a maximum attenuation.

Abstract: A variable resistance control employing a support plate and a resistance element having a pair of spaced resistance paths applied on a base and rotatably mounted on the support plate. A pair of terminals with integral contacts are secured to the support plate and are disposed intermediate the base and the support plate. The pair of resistive paths are concentrically disposed on a surface of the base and electrically connected to each other. Each of the contacts engages a respective one of the resistive paths. In the assembly of the control, terminals are initially joined by a bridging member and, after the terminals are secured to the support plate, the bridging member is severed from the terminals providing a pair of separate terminals with integral contacts.

Abstract: A solid state dimmer for fluorescent lights with standard (non-dimming) ballasts. Dimming is adjusted by changing the resistance in a capacitor charging circuit. Features include a trimming adjustment for eliminating flicker, a voltage regulator compensating for line voltage change, a sequential switch which allows the lamp to heat up before being dimmed, and a diode varistor, zener thyrector or the like in the charging circuit which supply additional charging current as the dimming is increased. The dimmer mounts in the same outlet box as a conventional toggle switch and can be substituted for the switch in an existing installation without changing the ballast. The dimmer is also useful for other loads requiring a variable voltage.
