摘要： A conductive polymer device includes an active element comprising a conductive polymeric layer laminated between a pair of electrodes to which terminal leads are attached. The active element is enclosed in an insulative package. Each of the electrodes may be formed integrally with its associated terminal lead in a single lead frame, with a layer of conductive polymeric material laminated between two such lead frames. Alternatively, a conductive polymeric layer may be laminated between two electrodes, with a terminal lead then being soldered to each electrode. The insulative package for the active element may be either an over-molded housing encasing the active element, or a pre-molded housing having a cavity into which the active element is installed, and which is then hermetically sealed with a suitable sealant material.

摘要： A ratcheting mechanism for a multiturn variable resistance device, of the worm screw-actuated type, has mutually engageable stopping members on the rotor and in the housing, limiting rotor travel beyond first and second limits. The stopping member in the housing has an inclined surface on one side which pivotally lifts the rotor against the force of the electrical contact spring (carried on one side of the rotor in contact with a resistive element), when the rotor reaches the first limit of travel. The pivoting action compresses the contact spring while allowing the spur gears on the rotor momentarily to disengage from the worm gear. This disengagement releases the spring, which then urges the rotor back into a gear-engaging position. The rotor is provided with at least one axially-shortened spur gear tooth positioned so as to be engageable with the worm gear when the rotor is at the second limit of travel. The further rotation of the rotor beyond the second limit of travel being inhibited by the engagement of the stopping member, the engagement of the shortened tooth with the worm gear pivotally lifts the rotor, thereby compressing the spring and momentarily disengaging the spur and worm gears. Following the momentary disengagement, the spring is released, thereby urging the rotor back into a gear-engaging position.
摘要翻译：用于蜗杆螺杆致动型的多圈可变电阻装置的棘轮机构在转子和壳体中具有相互接合的止动构件，限制转子超过第一和第二极限。壳体中的止动构件在一侧具有倾斜表面，该转动体抵抗抗接触弹簧（在与电阻元件接触的转子的一侧上承载）的力而转动，当转子达到第一极限旅行。枢转动作压缩接触弹簧，同时使转子上的正齿轮瞬间脱离蜗轮。这种脱离释放弹簧，弹簧然后将转子推回到齿轮啮合位置。转子设置有至少一个轴向缩短的正齿轮齿，其定位成当转子处于第二行驶极限时可与蜗轮啮合。转子超过第二限制行程的进一步转动被止动件接合所阻止，缩短的齿与蜗轮的啮合可以转动地提升转子，从而压缩弹簧并暂时脱开正齿轮和蜗轮。在瞬间脱离之后，释放弹簧，从而将转子推回到齿轮啮合位置。
