  • Patent number: 7489499
    Abstract: A captured offset linear guide system for a lighting control device includes a faceplate having an elongated slot, a knob, an offset member, and a linear potentiometer. The offset member allows the linear potentiometer to be offset from the elongated slot of the faceplate to prevent dirt and dust from collecting on the potentiometer. Also, the offset linear guide system prevents insertion of an object into the internal structure of the lighting control device where it might come into contact with energized electrical components. The faceplate includes two guide rails, which hold the offset member close to the faceplate and allow for easy assembly of the faceplate to the lighting control device. Further, the faceplate includes an alignment rail, which prevents the offset member from rotating and further constrains the offset member to move in a straight line within the slot.

  • Publication number: 20080164970
    Abstract: A contactless potentiometer is described wherein the conductive and resistive traces of the potentiometer are contained within a sealed channel formed of non-conductive material. The electrical gap between the conductive and resistive traces is bridged by a magnetically reactive contactless tap. A magnetic force is applied to the tap through the surface of the channel holding the conductive and resistive traces. This provides a drawing magnetic force to the tap which pulls the tap against the traces and allows for changing the resistance of the potentiometer by laterally moving the tap along the traces as the tap moves to follow the motion of the external force.

    Abstract: A thin-thickness variable resistor is provided, which is capable of stabilizing electrical connection between metallic terminals and a resistor by increasing the holding strength for a second terminal by a substrate while preventing the bending strain during the bending work from spreading to a conductive portion conductive to the resistor. A variable resistor comprises a substrate, metallic terminals formed in the substrate by insert-molding, and a slider sliding on a resistor formed on the substrate, wherein the slider is rotatably attached by crimping an eyelet formed in a first metallic terminal. External-connecting portions of the metallic terminals are extended from the bottom portion of the substrate to be bent upwardly along sides of the substrate.

  • Patent number: 6392529
    Abstract: An electrical contactor or wiper that uses an elastomer near the tip to reduce flexing and improve electrical signal accuracy. The contactor includes an elongated beam having a U-shaped end. Several carbon fibers form a bundle attached to the beam. The fibers have ends and tips. The ends are compressively held inside the U-shaped end and the tips emanate from the U-shaped end. An elastomer is disposed over the carbon fibers where they emanate from the U-shaped end. The elastomer reduces flexing of the carbon fibers. The elastomer is located between the beam and adjacent to the tips with the tips being exposed. A laser is used to trim the carbon fibers and elastomer to form the tips.

  • Patent number: 6369690
    Abstract: A resistor card for a potentiometer to measure the fuel in a fuel tank consists of a non-conductive substrate with a plurality of elongate conductive contacts deposited thereon. The contacts have an elevation above the surface of the substrate and the contacts are oriented in parallel relationship to each other to form a wiper track across which a wiper is moveable. To reduce the rate at which the upper surfaces of the contacts are worn away by movement of the wiper, an insulating or highly resistive filler material is deposited between the conductive materials which form the lands.

  • Patent number: 6359545
    Abstract: The invention relates to an adjustable resistor comprising a strip of resistance material arranged on an insulating carrier and a slider made of conductive material guidable along the strip and contacting the strip, wherein the slider is manufactured from elastomeric material. A slider manufactured from an elastomeric material will, as a result of its flexibility, make contact with the resistance strip over a relatively large part of the width of the resistance strip so flat the problems of an uneven current distribution associated with one-point contact are avoided. The use of an elastomeric material further provides the option of dimensioning and shaping the slider such that it can be handled easily by means of a positioning machine, and the problems of the usually elongate rigid sliders on the production line are avoided. The slider is preferably manufactured from conductive rubber or a conductive plastic.

  • Publication number: 20020024415
    Abstract: A resistive element includes a resistive film disposed on an insulating film, a current collector disposed apart from the resistive film at a given space, and an electrode conductive to the resistive film and the collector respectively. The insulating board is punched to form slits which split the electrode. The slits allow the resistive element to maintain creepage distances between the electrode. The resistive element accommodates downsizing requirement while restraining silver migration for eliminating shorts between the electrodes. As a result, a highly reliable resistive element is obtainable.

  • Patent number: 6292090
    Abstract: A switch circuit including voltage dividing elements for dividing a reference voltage inputted from an external source through a reference voltage input terminal, a fixed contact having metallic patterns formed on a board, and a movable contact coming in contact with the metallic patterns so as to slide thereon. The switch circuit not only divides the reference voltage at a voltage dividing ratio corresponding to a currently selected position of an object whose position is to be detected, but also outputs the divided voltage as an analog signal. Some of the voltage dividing elements that serve to switch the voltage dividing ratios are connected in parallel to one another through the fixed contact and the movable contact.

  • Patent number: 6285276
    Abstract: A control device is provided for an industrial truck, in particular the towbar of a towbar-guided industrial truck, having a circuit element to generate a multi-stage electrical control signal. The invention teaches that the switching element has at least one contact membrane (6) which can be electrically connected by a pressure force exerted on the contact membrane (6) with at least one of a plurality of contact points (2) that correspond to the contact membrane (6). The contact points (2) are connected by electrical resistors (R1-8). The electrical resistors (R1-8) are preferably connected in series, whereby the connecting line between each two resistors is connected to a contact point (2). There are two sliders (8a, b), each of which exerts a pressure force on the contact membrane (6), as a result of which a contact point (2) can be connected to a contact area (3).

  • Publication number: 20010003435
    Abstract: An angle sensor in which, when a biasing member is used, a biasing force in the &bgr;2 direction acts on a driving gear, and a biasing force in the &bgr;1 direction acts on an auxiliary gear. This prevents backlash from occurring between a rotary member and the driving member, making it possible to reduce rattling between the rotary member and the driving member. A fitting member is provided at the free end side of a resilient supporting member in order to resiliently press a screw shaft in the Z1 direction. Therefore, internal threads of inside surfaces of corresponding fitting portions of the fitting member and thread grooves of the screw shaft can be made to uniformly closely contact each other, making it possible reduce rattling caused by backlash therebetween. Consequently, the angle of rotation of a steering wheel which is mounted to the rotary member is detected with high precision.
